ES Executive Summary

Land, including its water bodies, provides the basis for human livelihoods and well-being through primary productivity, the supply of food, freshwater, and multiple other ecosystem services ( high confidence ) . Neither our individual or societal identities, nor the world’s economy would exist without the multiple resources, services and livelihood systems provided by land ecosystems and biodiversity. The annual value of the world’s total terrestrial ecosystem services has been estimated at 75 trillion USD in 2011, approximately equivalent to the annual global Gross Domestic Product (based on USD2007 values) ( medium confidence ). Land and its biodiversity also represent essential, intangible benefits to humans, such as cognitive and spiritual enrichment, sense of belonging and aesthetic and recreational values. Valuing ecosystem services with monetary methods often overlooks these intangible services that shape societies, cultures and quality of life and the intrinsic value of biodiversity. The Earth’s land area is finite. Using land resources sustainably is fundamental for human well-being ( high confidence ). {1.1.1}

The current geographic spread of the use of land, the large appropriation of multiple ecosystem services and the loss of biodiversity are unprecedented in human history ( high confidence ). By 2015, about three-quarters of the global ice-free land surface was affected by human use. Humans appropriate one-quarter to one-third of global terrestrial potential net primary production ( high confidence ). Croplands cover 12–14% of the global ice-free surface. Since 1961, the supply of global per capita food calories increased by about one-third, with the consumption of vegetable oils and meat more than doubling. At the same time, the use of inorganic nitrogen fertiliser increased by nearly ninefold, and the use of irrigation water roughly doubled ( high confidence ). Human use, at varying intensities, affects about 60–85% of forests and 70–90% of other natural ecosystems (e.g., savannahs, natural grasslands) ( high confidence ). Land use caused global biodiversity to decrease by around 11–14% ( medium confidence ). {1.1.2}

Warming over land has occurred at a faster rate than the global mean and this has had observable impacts on the land system ( high confidence ). The average temperature over land for the period 2006–2015 was 1.53°C higher than for the period 1850–1900, and 0.66°C larger than the equivalent global mean temperature change. These warmer temperatures (with changing precipitation patterns) have altered the start and end of growing seasons, contributed to regional crop yield reductions, reduced freshwater availability, and put biodiversity under further stress and increased tree mortality ( high confidence ). Increasing levels of atmospheric CO ₂ , have contributed to observed increases in plant growth as well as to increases in woody plant cover in grasslands and savannahs ( medium confidence ). {1.1.2}

Urgent action to stop and reverse the over-exploitation of land resources would buffer the negative impacts of multiple pressures, including climate change, on ecosystems and society ( high confidence ). Socio-economic drivers of land-use change such as technological development, population growth and increasing per capita demand for multiple ecosystem services are projected to continue into the future ( high confidence ). These and other drivers can amplify existing environmental and societal challenges, such as the conversion of natural ecosystems into managed land, rapid urbanisation, pollution from the intensification of land management and equitable access to land resources ( high confidence ). Climate change will add to these challenges through direct, negative impacts on ecosystems and the services they provide ( high confidence ). Acting immediately and simultaneously on these multiple drivers would enhance food, fibre and water security, alleviate desertification, and reverse land degradation, without compromising the non-material or regulating benefits from land ( high confidence ). {1.1.2, 1.2.1, 1.3.2–1.3.6, Cross-Chapter Box 1 in Chapter 1}

Rapid reductions in anthropogenic greenhouse gas (GHG) emissions that restrict warming to “well-below” 2°C would greatly reduce the negative impacts of climate change on land ecosystems ( high confidence ). In the absence of rapid emissions reductions, reliance on large-scale, land-based, climate change mitigation is projected to increase, which would aggravate existing pressures on land ( high confidence ). Climate change mitigation efforts that require large land areas (e.g., bioenergy and afforestation/reforestation) are projected to compete with existing uses of land ( high confidence ). The competition for land could increase food prices and lead to further intensification (e.g., fertiliser and water use) with implications for water and air pollution, and the further loss of biodiversity ( medium confidence ). Such consequences would jeopardise societies’ capacity to achieve many Sustainable Development Goals (SDGs) that depend on land ( high confidence ). {1.3.1, Cross-Chapter Box 2 in Chapter 1}

Nonetheless, there are many land-related climate change mitigation options that do not increase the competition for land ( high confidence ). Many of these options have co-benefits for climate change adaptation ( medium confidence ). Land use contributes about one-quarter of global greenhouse gas emissions, notably CO ₂ emissions from deforestation, CH ₄ emissions from rice and ruminant livestock and N ₂ O emissions from fertiliser use ( high confidence ). Land ecosystems also take up large amounts of carbon ( high confidence ). Many land management options exist to both reduce the magnitude of emissions and enhance carbon uptake. These options enhance crop productivity, soil nutrient status, microclimate or biodiversity, and thus, support adaptation to climate change ( high confidence ). In addition, changes in consumer behaviour, such as reducing the over-consumption of food and energy would benefit the reduction of GHG emissions from land ( high confidence ). The barriers to the implementation of mitigation and adaptation options include skills deficit, financial and institutional barriers, absence of incentives, access to relevant technologies, consumer awareness and the limited spatial scale at which the success of these practices and methods have been demonstrated. {1.2.1, 1.3.2, 1.3.3, 1.3.4, 1.3.5, 1.3.6}

Sustainable food supply and food consumption, based on nutritionally balanced and diverse diets, would enhance food security under climate and socio-economic changes ( high confidence ). Improving food access, utilisation, quality and safety to enhance nutrition, and promoting globally equitable diets compatible with lower emissions have demonstrable positive impacts on land use and food security ( high confidence ). Food security is also negatively affected by food loss and waste (estimated as 25–30% of total food produced) ( medium confidence ). Barriers to improved food security include economic drivers (prices, availability and stability of supply) and traditional, social and cultural norms around food eating practices . Climate change is expected to increase variability in food production and prices globally ( high confidence ), but the trade in food commodities can buffer these effects. Trade can provide embodied flows of water, land and nutrients ( medium confidence ). Food trade can also have negative environmental impacts by displacing the effects of overconsumption ( medium confidence ). Future food systems and trade patterns will be shaped as much by policies as by economics ( medium confidence ). {1.2.1, 1.3.3}

A g ender-inclusive approach offers opportunities to enhance the sustainable management of land ( medium confidence ). Women play a significant role in agriculture and rural economies globally. In many world regions, laws, c ultural restrictions, patriarchy and social structures such as discriminatory customary laws and norms reduce women’s capacity in supporting the sustainable use of land resources ( medium confidence ). Therefore, acknowledging women’s land rights and bringing women’s land management knowledge into land-related decision-making would support the alleviation of land degradation, and facilitate the take-up of integrated adaptation and mitigation measures ( medium confidence ). {1.4.1, 1.4.2}

Regional and country specific contexts affect the capacity to respond to climate change and its impacts, through adaptation and mitigation ( high confidence ). There is large variability in the availability and use of land resources between regions, countries and land management systems. In addition, differences in socio-economic conditions, such as wealth, degree of industrialisation, institutions and governance, affect the capacity to respond to climate change, food insecurity, land degradation and desertification. The capacity to respond is also strongly affected by local land ownership. Hence, climate change will affect regions and communities differently ( high confidence ). {1.3, 1.4}

Cross-scale, cross-sectoral and inclusive governance can enable coordinated policy that supports effective adaptation and mitigation ( high confidence ). There is a lack of coordination across governance levels, for example, local, national, transboundary and international, in addressing climate change and sustainable land management challenges. Policy design and formulation is often strongly sectoral, which poses further barriers when integrating international decisions into relevant (sub)national policies. A portfolio of policy instruments that are inclusive of the diversity of governance actors would enable responses to complex land and climate challenges ( high confidence ). Inclusive governance that considers women’s and indigenous people’s rights to access and use land enhances the equitable sharing of land resources, fosters food security and increases the existing knowledge about land use, which can increase opportunities for adaptation and mitigation ( medium confidence ). {1.3.5, 1.4.1, 1.4.2, 1.4.3}

Scenarios and models are important tools to explore the trade-offs and co-benefits of land management decisions under uncertain futures ( high confidence ). Participatory, co-creation processes with stakeholders can facilitate the use of scenarios in designing future sustainable development strategies ( medium confidence ). In addition to qualitative approaches, models are critical in quantifying scenarios, but uncertainties in models arise from, for example, differences in baseline datasets, land cover classes and modelling paradigms ( medium confidence ). Current scenario approaches are limited in quantifying time-dependent policy and management decisions that can lead from today to desirable futures or visions. Advances in scenario analysis and modelling are needed to better account for full environmental costs and non-monetary values as part of human decision-making processes. {1.2.2, Cross-Chapter Box 1 in Chapter 1}

1.1 Introduction and scope of the report

1.1.1 Objectives and scope of the assessment

Land, including its water bodies, provides the basis for our livelihoods through basic processes such as net primary production that fundamentally sustain the supply of food, bioenergy and freshwater, and the delivery of multiple other ecosystem services and biodiversity (Hoekstra and Wiedmann 2014 ¹ ; Mace et al. 2012 ² ; Newbold et al. 2015 ³ ; Runting et al. 2017 ⁴ ; Isbell et al. 2017 ⁵ ) (Cross-Chapter Box 8 in Chapter 6). The annual value of the world’s total terrestrial ecosystem services has been estimated to be about 75 trillion USD in 2011, approximately equivalent to the annual global Gross Domestic Product (based on USD2007 values) (Costanza et al. 2014 ⁶ ; IMF 2018 ⁷ ). Land also supports non-material ecosystem services such as cognitive and spiritual enrichment and aesthetic values (Hernández-Morcillo et al. 2013 ⁸ ; Fish et al. 2016 ⁹ ), intangible services that shape societies, cultures and human well-being. Exposure of people living in cities to (semi-)natural environments has been found to decrease mortality, cardiovascular disease and depression (Rook 2013 ¹⁰ ; Terraube et al. 2017 ¹¹ ). Non-material and regulating ecosystem services have been found to decline globally and rapidly, often at the expense of increasing material services (Fischer et al. 2018 ¹² ; IPBES 2018a ¹³ ). Climate change will exacerbate diminishing land and freshwater resources, increase biodiversity loss, and will intensify societal vulnerabilities, especially in regions where economies are highly dependent on natural resources. Enhancing food security and reducing malnutrition, whilst also halting and reversing desertification and land degradation, are fundamental societal challenges that are increasingly aggravated by the need to both adapt to and mitigate climate change impacts without compromising the non-material benefits of land (Kongsager et al. 2016 ¹⁴ ; FAO et al. 2018 ¹⁵ ).

Annual emissions of GHGs and other climate forcers continue to increase unabatedly. Confidence is very high that the window of opportunity, the period when significant change can be made, for limiting climate change within tolerable boundaries is rapidly narrowing (Schaeffer et al. 2015 ¹⁶ ; Bertram et al. 2015 ¹⁷ ; Riahi et al. 2015 ¹⁸ ; Millar et al. 2017 ¹⁹ ; Rogelj et al.   2018a ²⁰ ). The Paris Agreement formulates the goal of limiting global warming this century to well below 2°C above pre-industrial levels, for which rapid actions are required across the energy, transport, infrastructure and agricultural sectors, while factoring in the need for these sectors to accommodate a growing human population (Wynes and Nicholas 2017 ²¹ ; Le Quere et al. 2018 ²² ). Conversion of natural land, and land management, are significant net contributors to GHG emissions and climate change, but land ecosystems are also a GHG sink (Smith et al. 2014 ²³ ; Tubiello et al. 2015 ²⁴ ; Le Quere et al. 2018 ²⁵ ; Ciais et al. 2013a ²⁶ ). It is not surprising, therefore, that land plays a prominent role in many of the Nationally Determined Contributions (NDCs) of the parties to the Paris Agreement (Rogelj et al. 2018a ²⁷ ,b ²⁸ ; Grassi et al. 2017 ²⁹ ; Forsell et al. 2016 ³⁰ ), and land-measures will be part of the NDC review by 2023.

A range of different climate change mitigation and adaptation options on land exist, which differ in terms of their environmental and societal implications (Meyfroidt 2018 ³¹ ; Bonsch et al. 2016 ³² ; Crist et al. 2017 ^[[#fn:r|]] 33 ; Humpenoder et al. 2014 ³⁴ ; Harvey and Pilgrim 2011 ³⁵ ; Mouratiadou et al. 2016 ³⁶ ; Zhang et al. 2015 ³⁷ ; Sanz-Sanchez et al. 2017 ³⁸ ; Pereira et al. 2010 ³⁹ ; Griscom et al. 2017 ⁴⁰ ; Rogelj et al. 2018a ⁴¹ ) (Chapters 4–6). The Special Report on climate change, desertification, land degradation, sustainable land management, food security, and GHG fluxes in terrestrial ecosystems (SRCCL) synthesises the current state of scientific knowledge on the issues specified in the report’s title (Figure 1.1 and Figure 1.2). This knowledge is assessed in the context of the Paris Agreement, but many of the SRCCL issues concern other international conventions such as the United Nations Convention on Biodiversity (UNCBD), the UN Convention to Combat Desertification (UNCCD), the UN Sendai Framework for Disaster Risk Reduction (UNISDR) and the UN Agenda 2030 and its Sustainable Development Goals (SDGs). The SRCCL is the first report in which land is the central focus since the IPCC Special Report on land use, land-use change and forestry (Watson et al. 2000 ⁴² ) (Box 1.1). The main objectives of the SRCCL are to:

1. Assess the current state of the scientific knowledge on the impacts of socio-economic drivers and their interactions with climate change on land, including degradation, desertification and food security;
2. Evaluate the feasibility of different land-based response options to GHG mitigation, and assess the potential synergies and trade-offs with ecosystem services and sustainable development;
3. Examine adaptation options under a changing climate to tackle land degradation and desertification and to build resilient food systems, as well as evaluating the synergies and trade-offs between mitigation and adaptation;
4. Delineate the policy, governance and other enabling conditions to support climate mitigation, land ecosystem resilience and food security in the context of risks, uncertainties and remaining knowledge gaps.

A representation of the principal land challenges and land-climate system processes covered in this assessment report.
A . The warming curves are averages of four datasets (Section 2.1, Figure 2.2 and Table 2.1). B . N ₂ O and CH ₄ from agriculture are from FAOSTAT; Net land-use change emissions of CO ₂ from forestry and other land use (including emissions from peatland fires since 1997) are from the annual Global Carbon Budget, using the mean of two bookkeeping models. All values expressed in units of CO ₂ -eq are based on AR5 100-year Global Warming Potential values without climate-carbon feedbacks (N ₂ O = 265; CH ₄ = 28) (Table SPM.1 and Section 2.3). C . Depicts shares of different uses of the global, ice-free land area for approximately the year 2015, ordered along a gradient of decreasing land-use intensity from left to right. Each bar represents a broad land cover category; the numbers on top are the total percentage of the ice-free area covered, with uncertainty ranges in brackets. Intensive pasture is defined as having a livestock density greater than 100 animals/km². The area of ‘forest managed for timber and other uses’ was calculated as total forest area minus ‘primary/intact’ forest area. (Section 1.2, Table 1.1, Figure 1.3). D . Note that fertiliser use is shown on a split axis (source: International Fertiliser Industry Association, www.ifastat.org/databases). The large percentage change in fertiliser use reflects the low level of use in 1961 and relates to both increasing fertiliser input per area as well as the expansion of fertilised cropland and grassland to increase food production (1.1, Figure 1.3). E . Overweight population is defined as having a body mass index (BMI) >25 kg m ^–2 (source: Abarca-Gómez et al. 2017 ⁴³ ); underweight is defined as BMI <18.5 kg m ^–2 . (Population density, source: United Nations, Department of Economic and Social Affairs 2017 ⁴⁴ ) (Sections 5.1 and 5.2). F . Dryland areas were estimated using TerraClimate precipitation and potential evapotranspiration (1980–2015) (Abatzoglou et al. 2018 ⁴⁵ ) to identify areas where the Aridity Index is below 0.65. Areas experiencing human caused desertification, after accounting for precipitation variability and CO ₂ fertilisation, are identified in Le et al. 2016. Population data for these areas were extracted from the gridded historical population database HYDE3.2 (Goldewijk et al. 2017 ⁴⁶ ). Areas in drought are based on the 12-month accumulation Global Precipitation Climatology Centre Drought Index (Ziese et al. 2014 ⁴⁷ ). The area in drought was calculated for each month (Drought Index below –1), and the mean over the year was used to calculate the percentage of drylands in drought that year. The inland wetland extent (including peatlands) is based on aggregated data from more than 2000 time series that report changes in local wetland area over time (Dixon et al. 2016 ⁴⁸ ; Darrah et al. 2019 ⁴⁹ ) (Sections 3.1, 4.2 and 4.6).

Box 1.1 Land in previous IPCC and other relevant reports

Previous IPCC reports have made reference to land and its role in the climate system. Threats to agriculture, forestry and other ecosystems, but also the role of land and forest management in climate change, have been documented since the IPCC Second Assessment Report, especially so in the Special Report on land use, land-use change and forestry (Watson et al. 2000 ⁵⁰ ). The IPCC Special Report on extreme events (SREX) discussed sustainable land management, including land-use planning, and ecosystem management and restoration among the potential low-regret measures that provide benefits under current climate and a range of future, climate change scenarios. Low-regret measures are defined in the report as those with the potential to offer benefits now  and lay the foundation for tackling future, projected change. Compared to previous IPCC reports, the SRCCL offers a more integrated analysis of the land system as it embraces multiple direct and indirect drivers of natural resource management (related to food, water and energy securities), which have not previously been addressed to a similar depth (Field et al. 2014a ⁵¹ ; Edenhofer et al. 2014 ⁵² ).

The recent IPCC Special Report on Global Warming of 1.5°C (SR15) targeted specifically the Paris Agreement, without exploring the possibility of future global warming trajectories above 2°C (IPCC 2018 ⁵³ ). Limiting global warming to 1.5°C compared to 2°C is projected to lower the impacts on terrestrial, freshwater and coastal ecosystems and to retain more of their services for people. In many scenarios proposed in this report, large-scale land use features as a mitigation measure. In the reports of the Food and Agriculture Organization (FAO), land degradation is discussed in relation to ecosystem goods and services, principally from a food security perspective (FAO and ITPS 2015 ⁵⁴ ). The UNCCD report (2014) discusses land degradation through the prism of desertification. It devotes due attention to how land management can contribute to reversing the negative impacts of desertification and land degradation. The IPBES assessments (2018a ⁵⁵ , b ⁵⁶ , c ⁵⁷ , d ⁵⁸ , e ⁵⁹ ) focus on biodiversity drivers, including a focus on land degradation and desertification, with poverty as a limiting factor. The reports draw attention to a world in peril in which resource scarcity conspires with drivers of biophysical and social vulnerability to derail the attainment of sustainable development goals. As discussed in Chapter 4 of the SRCCL, different definitions of degradation have been applied in the IPBES degradation assessment (IPBES 2018b ⁹²⁹ ), which potentially can lead to different conclusions for restoration and ecosystem management.

The SRCCL complements and adds to previous assessments, whilst keeping the IPCC-specific ‘climate perspective’. It includes a focussed assessment of risks arising from maladaptation and land-based mitigation (i.e. not only restricted to direct risks from climate change impacts) and the co-benefits and trade-offs with sustainable development objectives. As the SRCCL cuts across different policy sectors it provides the opportunity to address a number of challenges in an integrative way at the same time, and it progresses beyond other IPCC reports in having a much more comprehensive perspective on land.

The SRCCL identifies and assesses land-related challenges and response options in an integrative way, aiming to be policy relevant across sectors. Chapter 1 provides a synopsis of the main issues addressed in this report, which are explored in more detail in Chapters 2–7. Chapter 1 also introduces important concepts and definitions and highlights discrepancies with previous reports that arise from different objectives (a full set of definitions is provided in the Glossary). Chapter 2 focuses on the natural system dynamics, assessing recent progress towards understanding the impacts of climate change on land, and the feedbacks arising from altered biogeochemical and biophysical exchange fluxes (Figure 1.2).

Overview over the SRCCL.

1.1.2 Status and dynamics of the (global) land system

1.1.2.1 1.1.2.1 Land ecosystems and climate change

Land ecosystems play a key role in the climate system, due to their large carbon pools and carbon exchange fluxes with the atmosphere (Ciais et al. 2013b ⁶⁰ ). Land use, the total of arrangements, activities and inputs applied to a parcel of land (such as agriculture, grazing, timber extraction, conservation or city dwelling; see Glossary), and land management (sum of land-use practices that take place within broader land-use categories; see Glossary) considerably alter terrestrial ecosystems and play a key role in the global climate system. An estimated one-quarter of total anthropogenic GHG emissions arise mainly from deforestation, ruminant livestock and fertiliser application (Smith et al. 2014 ⁶¹ ; Tubiello et al. 2015 ⁶² ; Le Quere et al. 2018 ⁶³ ; Ciais et al. 2013a ⁶⁴ ), and especially methane (CH ₄ ) and nitrous oxide (N ₂ O) emissions from agriculture have been rapidly increasing over the last decades (Hoesly et al. 2018 ⁶⁵ ; Tian et al. 2019 ⁶⁶ ) (Figure 1.1 and Sections 2.3.2–2.3.3).

Globally, land also serves as a large CO ₂ sink, which was estimated for the period 2008–2017 to be nearly 30% of total anthropogenic emissions (Le Quere et al. 2015 ⁶⁷ ; Canadell and Schulze 2014 ⁶⁸ ; Ciais et al. 2013a ⁶⁹ ; Zhu et al. 2016 ⁷⁰ ) (Section 2.3.1). This sink has been attributed to increasing atmospheric CO ₂ concentration, a prolonged growing season in cool environments, or forest regrowth (Le Quéré et al. 2013 ⁷¹ ; Pugh et al. 2019 ⁷² ; Le Quéré et al. 2018 ⁷³ ; Ciais et al. 2013a ⁷⁴ ; Zhu et al. 2016 ⁷⁵ ). Whether or not this sink will persist into the future is one of the largest uncertainties in carbon cycle and climate modelling (Ciais et al. 2013a ⁷⁶ ; Bloom et al. 2016 ⁷⁷ ; Friend et al. 2014 ⁷⁸ ; Le Quere et al. 2018 ⁷⁹ ). In addition, changes in vegetation cover caused by land use (such as conversion of forest to cropland or grassland, and vice versa) can result in regional cooling or warming through altered energy and momentum transfer between ecosystems and the atmosphere. Regional impacts can be substantial, but whether the effect leads to warming or cooling depends on the local context (Lee et al. 2011 ⁸⁰ ; Zhang et al. 2014 ⁸¹ ; Alkama and Cescatti 2016 ⁸² ) (Section 2.6). Due to the current magnitude of GHG emissions and CO ₂ carbon dioxide removal in land ecosystems, there is high confidence that GHG reduction measures in agriculture, livestock management and forestry would have substantial climate change mitigation potential, with co-benefits for biodiversity and ecosystem services (Smith and Gregory 2013 ⁸⁴ ; Smith et al. 2014 ⁸⁵ ; Griscom et al. 2017 ⁸⁶ ) (Sections 2.6 and 6.3).

The mean temperature over land for the period 2006–2015 was 1.53°C higher than for the period 1850–1900, and 0.66°C larger than the equivalent global mean temperature change (Section 2.2). Climate change affects land ecosystems in various ways (Section 7.2). Growing seasons and natural biome boundaries shift in response to warming or changes in precipitation (Gonzalez et al. 2010 ⁸⁷ ; Wärlind et al. 2014 ⁸⁸ ; Davies-Barnard et al. 2015 ⁸⁹ ; Nakamura et al. 2017 ⁹⁰ ). Atmospheric CO ₂ increases have been attributed to underlie, at least partially, observed woody plant cover increase in grasslands and savannahs (Donohue et al. 2013 ⁹¹ ). Climate change-induced shifts in habitats, together with warmer temperatures, cause pressure on plants and animals (Pimm et al. 2014 ⁹² ; Urban et al. 2016 ⁹³ ). National cereal crop losses of nearly 10% have been estimated for the period 1964–2007 as a consequence of heat and drought weather extremes (Deryng et al. 2014 ⁹⁴ ; Lesk et al. 2016 ⁹⁵ ). Climate change is expected to reduce yields in areas that are already under heat and water stress (Schlenker and Lobell 2010 ⁹⁶ ; Lobell et al. 2011 ⁹⁷ , 2012 ⁹⁸ ; Challinor et al. 2014 ⁹⁹ ) (Section 5.2.2). At the same time, warmer temperatures can increase productivity in cooler regions (Moore and Lobell 2015 ¹⁰⁰ ) and might open opportunities for crop area expansion, but any overall benefits might be counterbalanced by reduced suitability in warmer regions (Pugh et al. 2016 ¹⁰¹ ; Di Paola et al. 2018 ¹⁰² ). Increasing atmospheric CO ₂ is expected to increase productivity and water use efficiency in crops and in forests (Muller et al. 2015 ¹⁰³ ; Nakamura et al. 2017 ¹⁰⁴ ; Kimball 2016 ¹⁰⁵ ). The increasing number of extreme weather events linked to climate change is also expected to result in forest losses; heat waves and droughts foster wildfires (Seidl et al. 2017 ¹⁰⁶ ; Fasullo et al. 2018 ¹⁰⁷ ) (Cross-Chapter Box 3 in Chapter 2). Episodes of observed enhanced tree mortality across many world regions have been attributed to heat and drought stress (Allen et al. 2010 ¹⁰⁸ ; Anderegg et al. 2012 ¹⁰⁹ ), whilst weather extremes also impact local infrastructure and hence transportation and trade in land-related goods (Schweikert et al. 2014 ¹¹⁰ ; Chappin and van der Lei 2014 ¹¹¹ ). Thus, adaptation is a key challenge to reduce adverse impacts on land systems (Section 1.3.6).

1.1.2.2 Current patterns of land use and land cover

Around three-quarters of the global ice-free land, and most of the highly productive land area, are by now under some form of land use (Erb et al. 2016a ¹¹² ; Luyssaert et al. 2014 ¹¹³ ; Venter et al. 2016 ¹¹⁴ ) (Table 1.1). One-third of used land is associated with changed land cover. Grazing land is the single largest land-use category, followed by used forestland and cropland. The total land area used to raise livestock is notable: it includes all grazing land and an estimated additional one-fifth of cropland for feed production (Foley et al. 2011 ¹¹⁵ ). Globally, 60–85% of the total forested area is used, at different levels of intensity, but information on management practices globally is scarce (Erb et al. 2016a). Large areas of unused (primary) forests remain only in the tropics and northern boreal zones (Luyssaert et al. 2014 ¹¹⁶ ; Birdsey and Pan 2015 ¹¹⁷ ; Morales-Hidalgo et al. 2015 ¹¹⁸ ; Potapov et al. 2017 ¹¹⁹ ; Erb et al. 2017 ¹²⁰ ), while 73–89% of other, non-forested natural ecosystems (natural grasslands, savannahs, etc.) are used. Large uncertainties relate to the extent of forest (32.0–42.5 million km ² ) and grazing land (39–62 million km ² ), due to discrepancies in definitions and observation methods (Luyssaert et al. 2014 ¹²¹ ; Erb et al. 2017; Putz and Redford 2010 ¹²² ; Schepaschenko et al. 2015 ¹²³ ; Birdsey and Pan 2015 ¹²⁴ ; FAO 2015a ¹²⁵ ; Chazdon et al. 2016a ¹²⁶ ; FAO 2018a ¹²⁷ ). Infrastructure areas (including settlements, transportation and mining), while being almost negligible in terms of extent, represent particularly pervasive land-use activities, with far-reaching ecological, social and economic implications (Cherlet et al. 2018 ¹²⁸ ; Laurance et al. 2014 ¹²⁹ ).

The large imprint of humans on the land surface has led to the definition of anthromes, i.e. large-scale ecological patterns created by the sustained interactions between social and ecological drivers. The dynamics of these ‘anthropogenic biomes’ are key for land-use impacts as well as for the design of integrated response options (Ellis and Ramankutty 2008 ¹³⁰ ; Ellis et al. 2010 ¹³¹ ; Cherlet et al. 2018 ¹³² ; Ellis et al. 2010 ¹³³ ) (Chapter 6).

The intensity of land use varies hugely within and among different land-use types and regions. Averaged globally, around 10% of the ice-free land surface was estimated to be intensively managed (such as tree plantations, high livestock density grazing, large agricultural inputs), two-thirds moderately and the remainder at low intensities (Erb et al. 2016a ¹³⁴ ). Practically all cropland is fertilised, with large regional variations. Irrigation is responsible for 70% of ground- or surface-water withdrawals by humans (Wisser et al. 2008 ¹³⁵ ; Chaturvedi et al. 2015 ¹³⁶ ; Siebert et al. 2015 ¹³⁷ ; FAOSTAT 2018 ¹³⁸ ). Humans appropriate one-quarter to one-third of the total potential net primary production (NPP), i.e. the NPP that would prevail in the absence of land use (estimated at about 60 GtC yr ^–1 ; Bajželj et al. 2014 ¹³⁹ ; Haberl et al. 2014 ¹⁴⁰ ), about equally through biomass harvest and changes in NPP due to land management. The current total of agricultural (cropland and grazing) biomass harvest is estimated at about 6 GtC yr ^–1 , around 50–60% of this is consumed by livestock. Forestry harvest for timber and wood fuel amounts to about 1 GtC yr ^–1 (Alexander et al. 2017 ¹⁴¹ ; Bodirsky and Müller 2014 ¹⁴² ; Lassaletta et al. 2014 ¹⁴³ , 2016; Mottet et al. 2017 ¹⁴⁴ ; Haberl et al. 2014 ¹⁴⁵ ; Smith et al. 2014 ¹⁴⁶ ; Bais et al. 2015 ¹⁴⁷ ; Bajželj et al. 2014 ¹⁴⁸ ) (Cross-Chapter Box 7 in Chapter 6).

1.1.2.3 Past and ongoing trends

Globally, cropland area changed by +15% and the area of permanent pastures by +8% since the early 1960s (FAOSTAT 2018 ¹⁴⁹ ), with strong regional differences (Figure 1.3). In contrast, cropland production since 1961 increased by about 3.5 times, the production of animal products by 2.5 times, and forestry by 1.5 times; in parallel with strong yield (production per unit area) increases (FAOSTAT 2018 ¹⁵⁰ ) (Figure 1.3). Per capita calorie supply increased by 17% since 1970 (Kastner et al. 2012 ¹⁵¹ ), and diet composition changed markedly, tightly associated with economic development and lifestyle: since the early 1960s, per capita dairy product consumption increased by a factor of 1.2, and meat and vegetable oil consumption more than doubled (FAO 2017 ¹⁵² , 2018b ¹⁵³ ; Tilman and Clark 2014 ¹⁵⁴ ; Marques et al. 2019 ¹⁵⁵ ). Population and livestock production represent key drivers of the global expansion of cropland for food production, only partly compensated by yield increases at the global level (Alexander et al. 2015 ¹⁵⁶ ). A number of studies have reported reduced growth rates or stagnation in yields in some regions in the last decades ( medium evidence, high agreement ; Lin and Huybers 2012 ¹⁵⁷ ; Ray et al. 2012 ¹⁵⁸ ; Elbehri, Aziz, Joshua Elliott 2015 ¹⁵⁹ ) (Section 5.2.2).

The past increases in agricultural production have been associated with strong increases in agricultural inputs (Foley et al. 2011 ¹⁶⁰ ; Siebert et al. 2015 ¹⁶¹ ; Lassaletta et al. 2016 ¹⁶² ) (Figures 1.1 and 1.3). Irrigation area doubled, total nitrogen fertiliser use increased by 800% (FAOSTAT 2018 ¹⁶³ ; IFASTAT 2018 ¹⁶⁴ ) since the early 1960s. Biomass trade volumes grew by a factor of nine (in tonnes dry matter yr ^–1 ) in this period, which is much stronger than production (FAOSTAT 2018 ¹⁶⁵ ), resulting in a growing spatial disconnect between regions of production and consumption (Friis et al. 2016 ¹⁶⁶ ; Friis and Nielsen 2017 ¹⁶⁷ ; Schröter et al. 2018 ¹⁶⁸ ; Liu et al. 2013 ¹⁶⁹ ; Krausmann and Langthaler 2019 ¹⁷⁰ ). Urban and other infrastructure areas expanded by a factor of two since 1960 (Krausmann et al. 2013 ¹⁷¹ ), resulting in disproportionally large losses of highly fertile cropland (Seto and Reenberg 2014 ¹⁷² ; Martellozzo et al. 2015 ¹⁷³ ; Bren d’Amour et al. 2016 ¹⁷⁴ ; Seto and Ramankutty 2016 ¹⁷⁵ ; van Vliet et al. 2017 ¹⁷⁶ ). World regions show distinct patterns of change (Figure 1.3).

Status and trends in the global land system: A . Trends in area, production and trade, and drivers of change. The map shows the global pattern of land systems (combination of maps Nachtergaele (2008) ¹⁷⁷ ; Ellis et al. (2010) ¹⁷⁸ ; Potapov et al. (2017) ¹⁷⁹ ; FAO’s Animal Production and Health Division (2018); livestock low/high relates to low or high livestock density, respectively). The inlay figures show, for the globe and seven world regions, from left to right: (a) Cropland, permanent pastures and forest (used and unused) areas, standardised to total land area, (b) production in dry matter per year per total land area, (c) trade in dry matter in percent of total domestic production, all for 1961 to 2014 (data from FAOSTAT (2018) ¹⁸⁰ and FAO (1963) ¹⁸¹ for forest area 1961). (d) drivers of cropland for food production between 1994 and 2011 (Alexander et al. 2015 ¹⁸² ). See panel “global” for legend. “Plant Produc., Animal P.”: changes in consumption of plant-based products and animal-products, respectively. B .Selected land-use pressures and impacts. The map shows the ratio between impacts on biomass stocks of land-cover conversions and of land management (changes that occur with land-cover types; only changes larger than 30 gC m ^–2 displayed; Erb et al. 2017 ¹⁸³ ), compared to the biomass stocks of the potential vegetation (vegetation that would prevail in the absence of land use, but with current climate). The inlay figures show, from left to right (e) the global Human Appropriation of Net Primary production (HANPP) in the year 2005, in gC m ^–2 yr ^–1 (Krausmann et al. 2013 ¹⁸⁴ ). The sum of the three components represents the NPP of the potential vegetation and consist of: (i) NPP _eco , i.e. the amount of NPP remaining in ecosystem after harvest, (ii) HANPP _harv , i.e. NPP harvested or killed during harvest, and (iii) HANPP _luc , i.e. NPP foregone due to land-use change. The sum of NPP _eco and HANPP _harv is the NPP of the actual vegetation (Haberl et al. 2014 ¹⁸⁵ ; Krausmann et al. 2013 ¹⁸⁶ ). The two central inlay figures show changes in land-use intensity, standardised to 2014, related to (f) cropland (yields, fertilisation, irrigated area) and (g) forestry harvest per forest area, and grazers and monogastric livestock density per agricultural area (FAOSTAT 2018). (h) Cumulative CO ₂ fluxes between land and the atmosphere between 2000 and 2014. LUC: annual CO ₂ land use flux due to changes in land cover and forest management; Sink _land : the annual CO ₂ land sink caused mainly by the indirect anthropogenic effects of environmental change (e.g, climate change and the fertilising effects of rising CO ₂ and N concentrations), excluding impacts of land-use change (Le Quéré et al. 2018 ¹⁸⁷ ) (Section 2.3)

While most pastureland expansion replaced natural grasslands, cropland expansion replaced mainly forests (Ramankutty et al. 2018 ¹⁸⁸ ; Ordway et al. 2017 ¹⁸⁹ ; Richards and Friess 2016 ¹⁹⁰ ). Noteworthy large conversions occurred in tropical dry woodlands and savannahs, for example, in the Brazilian Cerrado (Lehmann and Parr 2016 ¹⁹¹ ; Strassburg et al. 2017 ¹⁹² ), the South American Caatinga and Chaco regions (Parr et al. 2014 ¹⁹³ ; Lehmann and Parr 2016 ¹⁹⁴ ) or African savannahs (Ryan et al. 2016 ¹⁹⁵ ). More than half of the original 4.3–12.6 million km ² global wetlands (Erb et al. 2016a ¹⁹⁶ ; Davidson 2014 ¹⁹⁷ ; Dixon et al. 2016 ¹⁹⁸ ) have been drained; since 1970 the wetland extent index, developed by aggregating data field-site time series that report changes in local inland wetland area, indicates a decline of more than 30% (Darrah et al. 2019 ¹⁹⁹ ) (Figure 1.1 and Section 4.2.1). Likewise, one-third of the estimated global area that in a non-used state would be covered in forests (Erb et al. 2017 ²⁰⁰ ) has been converted to agriculture.

Global forest area declined by 3% since 1990 (about –5% since 1960) and continues to do so (FAO 2015a ²⁰¹ ; Keenan et al. 2015 ²⁰² ; MacDicken et al. 2015 ²⁰³ ; FAO 1963; Figure 1.1 ²⁰⁴ ), but uncertainties are large. Low agreement relates to the concomitant trend of global tree cover. Some remote-sensing based assessments show global net-losses of forest or tree cover (Li et al. 2016 ²⁰⁵ ; Nowosad et al. 2018 ²⁰⁶ ; Hansen et al. 2013 ²⁰⁷ ); others indicate a net gain (Song et al. 2018 ²⁰⁸ ). Tree-cover gains would be in line with observed and modelled increases in photosynthetic active tissues (‘greening’; Chen et al. 2019 ²⁰⁹ ; Zhu et al. 2016 ²¹⁰ ; Zhao et al. 2018 ²¹¹ ; de Jong et al. 2013 ²¹² ; Pugh et al. 2019 ²¹³ ; De Kauwe et al. 2016 ²¹⁴ ; Kolby Smith et al. 2015 ²¹⁵ ) (Box 2.3 in Chapter 2), but confidence remains low whether gross forest or tree-cover gains are as large, or larger, than losses. This uncertainty, together with poor information on forest management, affects estimates and attribution of the land carbon sink (Sections 2.3, 4.3 and 4.6). Discrepancies are caused by different classification schemes and applied thresholds (e.g., minimum tree height and tree-cover thresholds used to define a forest), the divergence of forest and tree cover, and differences in methods and spatiotemporal resolution (Keenan et al. 2015 ²¹⁶ ; Schepaschenko et al. 2015 ²¹⁷ ; Bastin et al. 2017 ²¹⁸ ; Sloan and Sayer 2015 ²¹⁹ ; Chazdon et al. 2016a ²²⁰ ; Achard et al. 2014 ²²¹ ). However, there is robust evidence  and high agreement that a net loss of forest and tree cover prevails in the tropics and a net gain, mainly of secondary, semi-natural and planted forests, in the temperate and boreal zones.

The observed regional and global historical land-use trends result in regionally distinct patterns of C fluxes between land and the atmosphere (Figure 1.3B). They are also associated with declines in biodiversity, far above background rates (Ceballos et al. 2015 ²²² ; De Vos et al. 2015 ²²³ ; Pimm et al. 2014 ²²⁴ ; Newbold et al. 2015 ²²⁵ ; Maxwell et al. 2016 ²²⁶ ; Marques et al. 2019 ²²⁷ ). Biodiversity losses from past global land-use change have been estimated to be about 8–14%, depending on the biodiversity indicator applied (Newbold et al. 2015 ²²⁸ ; Wilting et al. 2017 ²²⁹ ; Gossner et al. 2016 ²³⁰ ; Newbold et al. 2018 ²³¹ ; Paillet et al. 2010 ²³² ). In future, climate warming has been projected to accelerate losses of species diversity rapidly (Settele et al. 2014 ^[[#fn:r|]] 233; Urban et al. 2016 ²³⁴ ; Scholes et al. 2018 ²³⁵ ; Fischer et al. 2018 ²³⁶ ; Hoegh-Guldberg et al. 2018 ²³⁷ ). The concomitance of land-use and climate change pressures render ecosystem restoration a key challenge (Anderson-Teixeira 2018 ²³⁸ ; Yang et al. 2019 ²⁴⁰ ) (Sections 4.8 and 4.9).

1.2 Key challenges related to land use change

1.2.1 Land system change, land degradation, desertification and food security

1.2.1.1 Future trends in the global land system

Human population is projected to increase to nearly 9.8 (± 1) billion people by 2050 and 11.2 billion by 2100 (United Nations 2018 ²⁴¹ ). More people, a growing global middle class (Crist et al. 2017 ²⁴² ), economic growth, and continued urbanisation (Jiang and O’Neill 2017 ²⁴³ ) increase the pressures on expanding crop and pasture area and intensifying land management. Changes in diets, efficiency and technology could reduce these pressures (Billen et al. 2015 ²⁴⁴ ; Popp et al. 2016 ²⁴⁵ ; Muller et al. 2017 ²⁴⁶ ; Alexander et al. 2015 ²⁴⁷ ; Springmann et al. 2018 ²⁴⁸ ; Myers et al. 2017 ²⁴⁹ ; Erb et al. 2016c ²⁵⁰ ; FAO 2018b ²⁵¹ ) (Sections 5.3 and 6.2.2).

Given the large uncertainties underlying the many drivers of land use, as well as their complex relation to climate change and other biophysical constraints, future trends in the global land system are explored in scenarios and models that seek to span across these uncertainties (Cross-Chapter Box 1 in Chapter 1). Generally, these scenarios indicate a continued increase in global food demand, owing to population growth and increasing wealth. The associated land area needs are a key uncertainty, a function of the interplay between production, consumption, yields, and production efficiency (in particular for livestock and waste) (FAO 2018b; van Vuuren et al. 2017 ²⁵² ; Springmann et al. 2018 ²⁵³ ; Riahi et al. 2017 ²⁵⁴ ; Prestele et al. 2016 ²⁵⁵ ; Ramankutty et al. 2018 ²⁵⁶ ; Erb et al. 2016b ²⁵⁷ ; Popp et al. 2016 ²⁵⁸ ) (Section 1.3 and Cross-Chapter Box 1 in Chapter 1). Many factors, such as climate change, local contexts, education, human and social capital, policy-making, economic framework conditions, energy availability, degradation, and many more, affect this interplay, as discussed in all chapters of this report.

Global telecouplings in the land system, the distal connections and multidirectional flows between regions and land systems, are expected to increase, due to urbanisation (Seto et al. 2012 ²⁵⁹ ; van Vliet et al. 2017 ²⁶⁰ ; Jiang and O’Neill 2017 ²⁶¹ ; Friis et al. 2016 ²⁶² ), and international trade (Konar et al. 2016 ²⁶³ ; Erb et al. 2016b; Billen et al. 2015 ²⁶⁴ ; Lassaletta et al. 2016 ²⁶⁵ ). Telecoupling can support efficiency gains in production, but can also lead to complex cause–effect chains and indirect effects such as land competition or leakage (displacement of the environmental impacts; see Glossary), with governance challenges (Baldos and Hertel 2015 ²⁶⁶ ; Kastner et al. 2014 ²⁶⁷ ; Liu et al. 2013 ²⁶⁸ ; Wood et al. 2018 ²⁶⁹ ; Schröter et al. 2018 ²⁷⁰ ; Lapola et al. 2010 ²⁷¹ ; Jadin et al. 2016 ²⁷² ; Erb et al. 2016b; Billen et al. 2015 ²⁷³ ; Chaudhary and Kastner 2016 ²⁷⁴ ; Marques et al. 2019 ²⁷⁵ ; Seto and Ramankutty 2016 ²⁷⁶ ) (Section 1.2.1.5). Furthermore, urban growth is anticipated to occur at the expense of fertile (crop)land, posing a food security challenge, in particular in regions of high population density and agrarian-dominated economies, with limited capacity to compensate for these losses (Seto et al. 2012 ²⁷⁷ ; Güneralp et al. 2013 ²⁷⁸ ; Aronson et al. 2014 ²⁷⁹ ; Martellozzo et al. 2015 ²⁸⁰ ; Bren d’Amour et al. 2016 ²⁸¹ ; Seto and Ramankutty 2016 ²⁸² ; van Vliet et al. 2017 ²⁸³ ).

Future climate change and increasing atmospheric CO ₂ concentration are expected to accentuate existing challenges by, for example, shifting biomes or affecting crop yields (Baldos and Hertel 2015 ²⁸⁴ ; Schlenker and Lobell 2010 ²⁸⁵ ; Lipper et al. 2014 ²⁸⁶ ; Challinor et al. 2014 ²⁸⁷ ; Myers et al. 2017 ²⁸⁸ ) (Section 5.2.2), as well as through land-based climate change mitigation. There is high confidence that large-scale implementation of bioenergy or afforestation can further exacerbate existing challenges (Smith et al. 2016 ²⁸⁹ ) (Section 1.3.1 and Cross-Chapter Box 7 in Chapter 6).

1.2.1.2 Land degradation

As discussed in Chapter 4, the concept of land degradation, including its definition, has been used in different ways in different communities and in previous assessments (such as the IPBES Land Degradation and Restoration Assessment). In the SRCCL, land degradation is defined as a negative trend in land condition, caused by direct or indirect human-induced processes including anthropogenic climate change, expressed as long-term reduction or loss of at least one of the following: biological productivity, ecological integrity or value to humans. This definition applies to forest and non-forest land (Chapter 4 and Glossary).

Land degradation is a critical issue for ecosystems around the world due to the loss of actual or potential productivity or utility (Ravi et al. 2010 ²⁹¹ ; Mirzabaev et al. 2015 ²⁹² ; FAO and ITPS 2015 ²⁹³ ; Cerretelli et al. 2018 ²⁹⁴ ). Land degradation is driven to a large degree by unsustainable agriculture and forestry, socio-economic pressures, such as rapid urbanisation and population growth, and unsustainable production practices in combination with climatic factors (Field et al. 2014b ²⁹⁵ ; Lal 2009 ²⁹⁶ ; Beinroth et al. 1994 ²⁹⁷ ; Abu Hammad and Tumeizi 2012 ²⁹⁸ ; Ferreira et al. 2018 ²⁹⁹ ; Franco and Giannini 2005 ³⁰⁰ ; Abahussain et al. 2002 ³⁰¹ ).

Global estimates of the total degraded area vary from less than 10 million km ² to over 60 million km ² , with additionally large disagreement regarding the spatial distribution (Gibbs and Salmon 2015 ³⁰² ) (Section 4.3). The annual increase in the degraded land area has been estimated as 50,000–100,000 million km ² yr ^–1 (Stavi and Lal 2015 ³⁰³ ), and the loss of total ecosystem services equivalent to about 10% of the world’s GDP in the year 2010 (Sutton et al. 2016 ³⁰⁴ ). Although land degradation is a common risk across the globe, poor countries remain most vulnerable to its impacts. Soil degradation is of particular concern, due to the long period necessary to restore soils (Lal 2009; Stockmann et al. 2013 ³⁰⁵ ; Lal 2015 ³⁰⁶ ), as well as the rapid degradation of primary forests through fragmentation (Haddad et al. 2015 ³⁰⁷ ). Among the most vulnerable ecosystems to degradation are high-carbon- stock wetlands (including peatlands). Drainage of natural wetlands for use in agriculture leads to high CO ₂ emissions and degradation ( high confidence ) (Strack 2008 ³⁰⁸ ; Limpens et al. 2008 ³⁰⁹ ; Aich et al. 2014 ³¹⁰ ; Murdiyarso et al. 2015 ³¹¹ ; Kauffman et al. 2016 ³¹² ; Dohong et al. 2017 ³¹³ ; Arifanti et al. 2018 ³¹⁴ ; Evans et al. 2019 ³¹⁵ ). Land degradation is an important factor contributing to uncertainties in the mitigation potential of land-based ecosystems (Smith et al. 2014 ³¹⁶ ). Furthermore, degradation that reduces forest (and agricultural) biomass and soil organic carbon leads to higher rates of runoff ( high confidence ) (Molina et al. 2007 ³¹⁷ ; Valentin et al. 2008 ³¹⁸ ; Mateos et al. 2017 ³¹⁹ ; Noordwijk et al. 2017 ³²⁰ ) and hence to increasing flood risk ( low confidence ) (Bradshaw et al. 2007 ³²¹ ; Laurance 2007 ³²² ; van Dijk et al. 2009 ³²³ ).

1.2.1.3 Desertification

The SRCCL adopts the definition of the UNCCD of desertification, being land degradation in arid, semi-arid and dry sub-humid areas (drylands) (Glossary and Section 3.1.1). Desertification results from various factors, including climate variations and human activities, and is not limited to irreversible forms of land degradation (Tal 2010 ⁹³⁰ ; Bai et al. 2008 ⁹³¹ ). A critical challenge in the assessment of desertification is to identify a ‘non-desertified’ reference state (Bestelmeyer et al. 2015 ³²⁴ ). While climatic trends and variability can change the intensity of desertification processes, some authors exclude climate effects, arguing that desertification is a purely human-induced process of land degradation with different levels of severity and consequences (Sivakumar 2007 ³²⁵ ).

As a consequence of varying definitions and different methodologies, the area of desertification varies widely (D’Odorico et al. 2013 ³²⁶ ; Bestelmeyer et al. 2015 ³²⁷ ; and references therein). Arid regions of the world cover up to about 46% of the total terrestrial surface (about 60 million km ² ) (Pravalie 2016 ³²⁸ ; Koutroulis 2019 ³²⁹ ). Around 3 billion people reside in dryland regions (D’Odorico et al. 2013 ³³⁰ ; Maestre et al. 2016 ³³¹ ) (Section 3.1.1). In 2015, about 500 (360–620) million people lived within areas which experienced desertification between 1980s and 2000s (Figure 1.1and Section 3.1.1). The combination of low rainfall with frequently infertile soils renders these regions, and the people who rely on them, vulnerable to both climate change, and unsustainable land management ( high confidence ). In spite of the national, regional and international efforts to combat desertification, it remains one of the major environmental problems (Abahussain et al. 2002 ³³² ; Cherlet et al. 2018 ³³³ ).

1.2.1.4 Food security, food systems and linkages to land-based ecosystems

The High Level Panel of Experts of the Committee on Food Security define the food system as to “gather all the elements (environment, people, inputs, processes, infrastructures, institutions, etc.) and activities that relate to the production, processing, distribution, preparation and consumption of food, and the output of these activities, including socio-economic and environmental outcomes” (HLPE 2017 ³³⁴ ). Likewise, food security has been defined as “a situation that exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life” (FAO 2017 ³³⁵ ). By this definition, food security is characterised by food availability, economic and physical access to food, food utilisation and food stability over time. Food and nutrition security is one of the key outcomes of the food system (FAO 2018b ³³⁶ ; Figure 1.4).

After a prolonged decline, world hunger appears to be on the rise again, with the number of undernourished people having increased to an estimated 821 million in 2017, up from 804 million in 2016 and 784 million in 2015, although still below the 900 million reported in 2000 (FAO et al. 2018 ³³⁷ ) (Section 5.1.2). Of the total undernourished in 2018, for example, 256.5 million lived in Africa, and 515.1 million in Asia (excluding Japan). The same FAO report also states that child undernourishment continues to decline, but levels of overweight populations and obesity are increasing. The total number of overweight children in 2017 was 38–40 million worldwide, and globally up to around two billion adults are by now overweight (Section 5.1.2). FAO also estimated that close to 2000 million people suffer from micronutrient malnutrition (FAO 2018b ³³⁸ ).

Food insecurity most notably occurs in situations of conflict, and conflict combined with droughts or floods (Cafiero et al. 2018 ³³⁹ ; Smith et al. 2017 ³⁴⁰ ). The close parallel between food insecurity prevalence and poverty means that tackling development priorities would enhance sustainable land use options for climate mitigation.

Climate change affects the food system as changes in trends and variability in rainfall and temperature variability impact crop and livestock productivity and total production (Osborne and Wheeler 2013 ³⁴¹ ; Tigchelaar et al. 2018 ³⁴² ; Iizumi and Ramankutty 2015 ³⁴³ ), the nutritional quality of food (Loladze 2014 ³⁴⁴ ; Myers et al. 2014 ³⁴⁵ ; Ziska et al. 2016 ³⁴⁶ ; Medek et al. 2017 ³⁴⁷ ), water supply (Nkhonjera 2017 ³⁴⁸ ), and incidence of pests and diseases (Curtis et al. 2018 ³⁴⁹ ). These factors also impact on human health, increasing morbidity and affecting human ability to process ingested food (Franchini and Mannucci 2015 ³⁵⁰ ; Wu et al. 2016 ³⁵¹ ; Raiten and Aimone 2017 ³⁵² ). At the same time, the food system generates negative externalities (the environmental effects of production and consumption) in the form of GHG emissions

(Sections 1.1.2 and 2.3), pollution (van Noordwijk and Brussaard 2014 ³⁵³ ; Thyberg and Tonjes 2016 ³⁵⁴ ; Borsato et al. 2018 ³⁵⁵ ; Kibler et al. 2018 ³⁵⁶ ), water quality (Malone et al. 2014 ³⁵⁷ ; Norse and Ju 2015 ³⁵⁸ ), and ecosystem services loss (Schipper et al. 2014 ³⁵⁹ ; Eeraerts et al. 2017 ³⁶⁰ ) with direct and indirect impacts on climate change and reduced resilience to climate variability. As food systems are assessed in relation to their contribution to global warming and/or to land degradation (e.g., livestock systems) it is critical to evaluate their contribution to food security and livelihoods and to consider alternatives, especially for developing countries where food insecurity is prevalent (Röös et al. 2017 ³⁶¹ ; Salmon et al. 2018 ³⁶² ).

Food system (and its relations to land and climate):The food system is conceptualised through supply (production, processing, marketing and retailing) and demand (consumption and diets) that are shaped by physical, economic, social and cultural determinants influencing choices, access, utilisation, quality, safety and waste. Food system drivers (ecosystem services, economics and technology, social and cultural norms and traditions, and demographics) combine with the enabling conditions (policies, institutions and governance) to affect food system outcomes including food security, nutrition and health, livelihoods, economic and cultural benefits as well as environmental outcomes or side-effects (nutrient and soil loss, water use and quality, GHG emissions and other pollutants). Climate and climate change have direct impacts on the food system (productivity, variability, nutritional quality) while the latter contributes to local climate (albedo, evapotranspiration) and global warming (GHGs). The land system (function, structures, and processes) affects the food system directly (food production) and indirectly (ecosystem services) while food demand and supply processes affect land (land-use change) and land-related processes (e.g., land degradation, desertification) (Chapter 5).

1.2.1.5 Challenges arising from land governance

Land-use change has both positive and negative effects: it can lead to economic growth, but it can become a source of tension and social unrest leading to elite capture, and competition (Haberl 2015 ³⁶³ ). Competition for land plays out continuously among different use types (cropland, pastureland, forests, urban spaces, and conservation and protected lands) and between different users within the same land-use category (subsistence vs commercial farmers) (Dell’Angelo et al. 2017b ³⁶⁴ ). Competition is mediated through economic and market forces (expressed through land rental and purchases, as well as trade and investments). In the context of such transactions, power relations often disfavour disadvantaged groups such as small-scale farmers, indigenous communities or women (Doss et al. 2015 ³⁶⁵ ; Ravnborg et al. 2016 ³⁶⁶ ). These drivers are influenced to a large degree by policies, institutions and governance structures. Land governance determines not only who can access the land, but also the role of land ownership (legal, formal, customary or collective) which influences land use, land-use change and the resulting land competition (Moroni 2018 ³⁶⁷ ).

Globally, there is competition for land because it is a finite resource and because most of the highly productive land is already exploited by humans (Lambin and Meyfroidt 2011 ³⁶⁸ ; Lambin 2012 ³⁶⁹ ; Venter et al. 2016 ³⁷⁰ ). Driven by growing population, urbanisation, demand for food and energy, as well as land degradation, competition for land is expected to accentuate land scarcity in the future (Tilman et al. 2011 ³⁷¹ ; Foley et al. 2011 ³⁷² ; Lambin 2012 ³⁷³ ; Popp et al. 2016 ³⁷⁴ ) ( robust evidence, high agreement ). Climate change influences land use both directly and indirectly, as climate policies can also a play a role in increasing land competition via forest conservation policies, afforestation, or energy crop production (Section 1.3.1), with the potential for implications for food security (Hussein et al. 2013 ³⁷⁵ ) and local land-ownership.

An example of large-scale change in land ownership is the much-debated large-scale land acquisition (LSLA) by investors which peaked in 2008 during the food price crisis, the financial crisis, and has also been linked to the search for biofuel investments (Dell’Angelo et al. 2017a ³⁷⁶ ). Since 2000, almost 50 million hectares of land have been acquired, and there are no signs of stagnation in the foreseeable future (Land Matrix 2018 ³⁷⁷ ).The LSLA phenomenon, which largely targets agriculture, is widespread, including Sub-Saharan Africa, Southeast Asia, Eastern Europe and Latin America (Rulli et al. 2012 ³⁷⁸ ; Nolte et al. 2016 ³⁷⁹ ; Constantin et al. 2017 ³⁸⁰ ). LSLAs are promoted by investors and host governments on economic grounds (infrastructure, employment, market development) (Deininger et al. 2011 ³⁸¹ ), but their social and environmental impacts can be negative and significant (Dell’Angelo et al. 2017a ³⁸² ).

Much of the criticism of LSLA focuses on its social impacts, especially the threat to local communities’ land rights (especially indigenous people and women) (Anseeuw et al. 2011 ³⁸³ ) and displaced communities creating secondary land expansion (Messerli et al. 2014 ³⁸⁴ ; Davis et al. 2015 ³⁸⁵ ). The promises that LSLAs would develop efficient agriculture on non-forested, unused land (Deininger et al. 2011 ³⁸⁶ ) has so far not been fulfilled. However, LSLA is not the only outcome of weak land governance structures (Wang et al. 2016 ³⁸⁷ ): other forms of inequitable or irregular land acquisition can also be home-grown, pitting one community against a more vulnerable group (Xu 2018 ³⁸⁸ ) or land capture by urban elites (McDonnell 2017 ³⁸⁹ ). As demands on land are increasing, building governance capacity and securing land tenure becomes essential to attain sustainable land use, which has the potential to mitigate climate change, promote food security, and potentially reduce risks of climate-induced migration and associated risks of conflicts (Section 7.6).

 

1.2.2 Progress in dealing with uncertainties in assessing land processes in the climate system

1.2.2.1 Concepts related to risk, uncertainty and confidence

In context of the SRCCL, risk refers to the potential for the adverse consequences for human or (land-based) ecological systems, arising from climate change or responses to climate change. Risk related to climate change impacts integrates across the hazard itself, the time of exposure and the vulnerability of the system; the assessment of all three of these components, their interactions and outcomes, is uncertain (see Glossary for expanded definition, and Section 7.1.2). For instance, a risk to human society is the continued loss of productive land which might arise from climate change, mismanagement, or a combination of both factors. However, risk can also arise from the potential for adverse consequences from responses to climate change, such as widespread deployment of bioenergy which is intended to reduce GHG emissions and thus limit climate change, but can present its own risks to food security (Chapters 5–7).

Demonstrating with some statistical certainty that the climate or the land system affected by climate or land use has changed (detection),

and evaluating the relative contributions of multiple causal factors to that change (with a formal assessment of confidence (attribution); see Glossary) remain challenging aspects in both observations and models (Rosenzweig and Neofotis 2013 ³⁹⁰ ; Gillett et al. 2016 ³⁹¹ ; Lean 2018 ³⁹² ). Uncertainties arising for example, from missing or imprecise data, ambiguous terminology, incomplete process representation in models, or human decision-making contribute to these challenges, and some examples are provided in this subsection. In order to reflect various sources of uncertainties in the state of scientific understanding, IPCC assessment reports provide estimates of confidence (Mastrandrea et al. 2011 ³⁹³ ). This confidence language is also used in the SRCCL (Figure 1.5).

1.2.2.2 Nature and scope of uncertainties related to land use

Identification and communication of uncertainties is crucial to support decision making towards sustainable land management. Providing a robust, and comprehensive understanding of uncertainties in observations, models and scenarios is a fundamental first step in the IPCC confidence framework (see above). This will remain a challenge in future, but some important progress has been made over recent years.

Uncertainties in observations

The detection of changes in vegetation cover and structural properties underpins the assessment of land-use change, degradation and desertification. It is continuously improving by enhanced Earth observation capacity (Hansen et al. 2013 ³⁹⁴ ; He et al. 2018 ³⁹⁵ ; Ardö et al. 2018 ³⁹⁶ ; Spennemann et al. 2018 ³⁹⁷ ) (see also Table SM.1.1 in Supplementary Material). Likewise, the picture of how soil organic carbon, and GHG and water fluxes, respond to land-use change and land management continues to improve through advances in methodologies and sensors (Kostyanovsky et al. 2018 ³⁹⁸ ; Brümmer et al. 2017 ³⁹⁹ ; Iwata et al. 2017 ⁴⁰⁰ ; Valayamkunnath et al. 2018 ⁴⁰¹ ). In both cases, the relative shortness of the record, data gaps, data treatment algorithms and – for remote sensing – differences in the definitions of major vegetation-cover classes limit the detection of trends (Alexander et al. 2016a ⁴⁰² ; Chen et al. 2014 ⁴⁰³ ; Yu et al. 2014 ⁴⁰⁴ ; Lacaze et al. 2015 ⁴⁰⁵ ; Song 2018 ⁴⁰⁶ ; Peterson et al. 2017 ⁴⁰⁷ ). In many developing countries, the cost of satellite remote sensing remains a challenge, although technological advances are starting to overcome this problem (Santilli et al. 2018 ⁴⁰⁸ ), while ground-based observations networks are often not available.

Integration of multiple data sources in model and data assimilation schemes reduces uncertainties (Li et al. 2017 ⁴⁰⁹ ; Clark et al. 2017 ⁴¹⁰ ; Lees et al. 2018 ⁴¹¹ ), which might be important for the advancement of early warning systems. Early warning systems are a key feature of short-term (i.e. seasonal) decision-support systems and are becoming increasingly important for sustainable land management and food security (Shtienberg 2013 ⁴¹² ; Jarroudi et al. 2015 ⁴¹³ ) (Sections 6.2.3 and 7.4.3). Early warning systems can help to optimise fertiliser and water use, aid disease suppression, and/or increase the economic benefit by enabling strategic farming decisions on when and what to plant (Caffi et al. 2012 ⁴¹⁴ ; Watmuff et al. 2013 ⁴¹⁵ ; Jarroudi et al. 2015 ⁴¹⁶ ; Chipanshi et al. 2015 ⁴¹⁷ ). Their suitability depends on the capability of the methods to accurately predict crop or pest developments, which in turn depends on expert agricultural knowledge, and the accuracy of the weather data used to run phenological models (Caffi et al. 2012 ⁴¹⁸ ; Shtienberg 2013 ⁴¹⁹ ).

Uncertainties in models

Model intercomparison is a widely used approach to quantify some sources of uncertainty in climate change, land-use change and ecosystem modelling, often associated with the calculation of model-ensemble medians or means (see e.g., Sections 2.2 and 5.2). Even models of broadly similar structure differ in their projected outcome for the same input, as seen for instance in the spread in climate change projections from Earth System Models (ESMs) to similar future anthropogenic GHG emissions (Parker 2013 ⁹³² ; Stocker et al. 2013a ⁹³³ ). These uncertainties arise, for instance, from different parameter values, different processes represented in models, or how these processes are mathematically described. If the outputs of ESM simulations are used as input to impact models, these uncertainties can propagate to projected impacts (Ahlstrom et al. 2013 ⁴²⁰ ).

Thus, the increased quantification of model performance in benchmarking exercises (the repeated confrontation of models with observations to establish a track-record of model developments and performance) is an important development to support the design and the interpretation of the outcomes of model ensemble studies (Randerson et al. 2009 ⁴²¹ ; Luo et al. 2012 ⁴²² ; Kelley et al. 2013 ⁴²³ ). Since observational datasets in themselves are uncertain, benchmarking benefits from transparent information on the observations that are used, and the inclusion of multiple, regularly updated data sources (Luo et al. 2012 ⁴²⁴ ; Kelley et al. 2013 ⁴²⁵ ). Improved benchmarking approaches and the associated scoring of models may support weighted model means contingent on model performance. This could be an important step forward when calculating ensemble means across a range of models (Buisson et al. 2009 ⁴²⁶ ; Parker 2013 ⁴²⁷ ; Prestele et al. 2016 ⁴²⁸ ).

Uncertainties arising from unknown futures

Large differences exist in projections of future land-cover change, both between and within scenario projections (Fuchs et al. 2015 ⁴²⁹ ; Eitelberg et al. 2016 ⁴³⁰ ; Popp et al. 2016 ⁴³¹ ; Krause et al. 2017 ⁴³² ; Alexander et al. 2016a ⁴³³ ). These differences reflect the uncertainties associated with baseline data, thematic classifications, different model structures and model parameter estimation (Alexander et al. 2017a ⁴³⁴ ; Prestele et al. 2016 ⁴³⁵ ; Cross-Chapter Box 1 in Chapter 1). Likewise, projections of future land-use change are also highly uncertain, reflecting – among other factors – the absence of important crop, pasture and management processes in Integrated Assessment Models (Rose 2014 ⁴³⁶ ) (Cross-Chapter Box 1 in Chapter 1 ) and in models of the terrestrial carbon cycle (Arneth et al. 2017 ⁴³⁷ ). These processes have been shown to have large impacts on carbon stock changes (Arneth et al. 2017 ⁴³⁸ ). Common scenario frameworks are used to capture the range of future uncertainties in scenarios. The most commonly used recent framework in climate change studies is based on the Representative Concentration Pathways (RCPs) and the Shared Socio-economic Pathways (SSPs) (Popp et al. 2016 ⁴³⁹ ; Riahi et al. 2017 ⁴⁴⁰ ). The RCPs prescribe levels of radiative forcing (W m ^–2 ) arising from different atmospheric concentrations of GHGs that lead to different levels of climate change. For example, RCP2.6 (2.6 W m ^–2 ) is projected to lead to global mean temperature changes of about 0.9°C–2.3°C, and RCP8.5 (8.5 W m ^–2 ) to global mean temperature changes of about 3.2°C–5.4°C (van Vuuren et al. 2014 ⁴⁴¹ ).

The SSPs describe alternative trajectories of future socio-economic development with a focus on challenges to climate mitigation and challenges to climate adaptation (O’Neill et al. 2014 ⁴⁴² ). SSP1 represents a sustainable and cooperative society with a low-carbon economy and high capacity to adapt to climate change. SSP3 has social inequality that entrenches reliance on fossil fuels and limits adaptive capacity. SSP4 has large differences in income within and across world regions; it facilitates low-carbon economies in places, but limits adaptive capacity everywhere. SSP5 is a technologically advanced world with a strong economy that is heavily dependent on fossil fuels, but with high adaptive capacity. SSP2 is an intermediate case between SSP1 and SSP3 (O’Neill et al. 2014 ⁴⁴³ ). The SSPs are commonly used with models to project future land-use change (Cross-Chapter Box 1 in Chapter 1).

About this box

The land-climate system is complex and future changes are uncertain, but methods exist (collectively known as futures analysis) to help decision-makers in navigating through this uncertainty. Futures analysis comprises a number of different and widely used methods, such as scenario analysis (Rounsevell and Metzger 2010 ⁴⁴⁴ ), envisioning or target setting (Kok et al. 2018 ⁴⁴⁵ ), pathways analysis (IPBES 2016 ⁴⁴⁶ ; IPCC 2018 ⁴⁴⁷ ) ¹ , and conditional probabilistic futures (Vuuren et al. 2018 ⁴⁴⁸ ; Engstrom et al. 2016 ⁴⁴⁹ ; Henry et al. 2018 ⁴⁵⁰ ) (Table 1 in this Cross-Chapter Box). Scenarios and other methods to characterise the future can support a discourse with decision-makers about the sustainable development options that are available to them. All chapters of this assessment draw conclusions from futures analysis and so, the purpose of this box is to outline the principal methods used, their application domains, their uncertainties and their limitations.

Exploratory scenario analysis

Many exploratory scenarios are reported in climate and land system studies on climate change (Dokken 2014 ⁴⁵¹ ), such as related to land-based, climate change mitigation via reforestation/afforestation, avoided deforestation or bioenergy (Kraxner et al. 2013 ⁴⁵² ; Humpenoder et al. 2014 ⁴⁵³ ; Krause et al. 2017 ⁴⁵⁴ ) and climate change impacts and adaptation (Warszawski et al. 2014 ⁴⁵⁵ ). There are global-scale scenarios of food security (Foley et al. 2011 ⁴⁵⁶ ; Pradhan et al. 2013 ⁴⁵⁷ , 2014 ⁴⁵⁸ ), but fewer scenarios of desertification, land degradation and restoration (Wolff et al. 2018 ⁴⁵⁹ ). Exploratory scenarios combine qualitative ‘storylines’ or descriptive narratives of the underlying causes (or drivers) of change (Nakicenovic and Swart 2000 ⁴⁶⁰ ; Rounsevell and Metzger 2010 ⁴⁶¹ ; O’Neill et al. 2014 ⁴⁶² ) with quantitative projections from computer models. Different types of models are used for this purpose based on very different modelling paradigms, baseline data and underlying assumptions (Alexander et al. 2016a ⁴⁶³ ; Prestele et al. 2016 ⁴⁶⁴ ). Figure 1 in this Cross-Chapter Box below outlines how a combination of models can quantify these components as well as the interactions between them.

Exploratory scenarios often show that socio-economic drivers have a larger effect on land-use change than climate drivers (Harrison et al. 2014 ⁴⁶⁵ , 2016 ⁴⁶⁶ ). Of these, technological development is critical in affecting the production potential (yields) of food and bioenergy and the feed conversion efficiency of livestock (Rounsevell et al. 2006 ⁴⁶⁷ ; Wise et al. 2014 ^[[#fn:r|]] 468; Kreidenweis et al. 2018 ⁴⁶⁹ ), as well as the area of land needed for food production (Foley et al. 2011 ⁴⁷⁰ ; Weindl et al. 2017 ⁴⁷¹ ; Kreidenweis et al. 2018 ⁴⁷² ). Trends in consumption, for example, diets or waste reduction, are also fundamental in affecting land-use change (Pradhan et al. 2013 ⁴⁷³ ; Alexander et al. 2016b ⁴⁷⁴ ; Weindl et al. 2017 ⁴⁷⁵ ; Alexander et al. 2017 ⁴⁷⁶ ; Vuuren et al. 2018 ⁴⁷⁷ ; Bajželj et al. 2014 ⁴⁷⁸ ). Scenarios of land-based mitigation through large-scale bioenergy production and afforestation often lead to negative trade-offs with food security (food prices), water resources and biodiversity (Cross-Chapter Box 7 in Chapter 6).

Many exploratory scenarios are based on common frameworks such as the Shared Socio-economic Pathways (SSPs) (Popp et al. 2016 ⁴⁷⁹ ; Riahi et al. 2017 ⁴⁸⁰ ; Doelman et al. 2018 ⁴⁸¹ )) (Section 1.2). However, other methods are used. Stylised scenarios prescribe assumptions about climate and land-use change solutions, for example, dietary change, food waste reduction and afforestation areas (Pradhan et al. 2013 ⁴⁸² , 2014 ⁴⁸³ ; Kreidenweis et al. 2016 ⁴⁸⁴ ; Rogelj et al. 2018b ⁴⁸⁵ ; Seneviratne et al. 2018 ⁴⁸⁶ ; Vuuren et al. 2018 ⁴⁸⁷ ). These scenarios provide useful thought experiments, but the feasibility of achieving the stylised assumptions is often unknown. Shock scenarios explore the consequences of low probability, high-impact events such as pandemic diseases, cyber-attacks and failures in food supply chains (Challinor et al. 2018 ⁴⁸⁸ ), often in food security studies. Because of the diversity of exploratory scenarios, attempts have been made to categorise them into ‘archetypes’ based on the similarity between their assumptions in order to facilitate communication (IPBES 2018a ⁴⁸⁹ ).

Conditional probabilistic futures explore the consequences of model parameter uncertainty in which these uncertainties are conditional on scenario assumptions (Neill 2004 ⁴⁹⁰ ). Only a few studies have applied the conditional probabilistic approach to land-use futures (Brown et al. 2014 ⁴⁹¹ ; Engstrom et al. 2016 ⁴⁹² ; Henry et al. 2018 ⁴⁹³ ). By accounting for uncertainties in key drivers these studies show large ranges in land-use change, for example, global cropland areas of 893–2380 Mha by the end of the 21st century (Engstrom et al. 2016 ⁴⁹⁴ ). They also find that land-use targets may not be achieved, even across a wide range of scenario parameter settings, because of trade-offs arising from the competition for land (Henry et al. 2018 ⁴⁹⁵ ; Heck et al. 2018 ⁴⁹⁶ ). Accounting for uncertainties across scenario assumptions can lead to convergent outcomes for land-use change, which implies that certain outcomes are more robust across a wide range of uncertain scenario assumptions (Brown et al. 2014 ⁴⁹⁷ ).

In addition to global scale scenario studies, sub-national studies demonstrate that regional climate change impacts on the land system are highly variable geographically because of differences in the spatial patterns of both climate and socio-economic change (Harrison et al. 2014 ⁴⁹⁸ ). Moreover, the capacity to adapt to these impacts is strongly dependent on the regional, socio-economic context and coping capacity (Dunford et al. 2014 ⁴⁹⁹ ); processes that are difficult to capture in global scale scenarios. Regional scenarios are often co-created with stakeholders through participatory approaches (Kok et al. 2014 ⁵⁰⁰ ), which are powerful in reflecting diverse worldviews and stakeholder values. Stakeholder participatory methods provide additional richness and context to storylines, as well as providing salience and legitimacy for local stakeholders (Kok et al. 2014).

Normative scenarios: visions and pathways analysis

Normative scenarios reflect a desired or target-seeking future. Pathways analysis is important in moving beyond the ‘what if?’ perspective of exploratory scenarios to evaluate how normative futures might be achieved in practice, recognising that multiple pathways may achieve the same future vision. Pathways analysis focuses on consumption and behavioural changes through transitions and transformative solutions (IPBES 2018a ⁵⁰¹ ). Pathways analysis is highly relevant in support of policy, since it outlines sets of time-dependent actions and decisions to achieve future targets, especially with respect to sustainable development goals, as well as highlighting trade-offs and co-benefits (IPBES 2018a ⁵⁰² ). Multiple, alternative pathways have been shown to exist that mitigate trade-offs whilst achieving the priorities for future sustainable development outlined by governments and societal actors. Of these alternatives, the most promising focus on long-term societal transformations through education, awareness raising, knowledge sharing and participatory decision-making (IPBES 2018a ⁵⁰³ ).

What are the limitations of land-use scenarios?

Applying a common scenario framework (e.g., RCPs/SSPs) supports the comparison and integration of climate- and land-system scenarios, but a ‘climate-centric’ perspective can limit the capacity of these scenarios to account for a wider range of land-relevant drivers (Rosa et al. 2017 ⁵⁰⁴ ). For example, in climate mitigation scenarios it is important to assess the impact of mitigation actions on the broader environment such as biodiversity, ecosystem functioning, air quality, food security, desertification/degradation and water cycles (Rosa et al. 2017 ⁵⁰⁵ ). This implies the need for a more encompassing and flexible approach to creating scenarios that considers other environmental aspects, not only as a part of impact assessment, but also during the process of creating the scenarios themselves.

A limited number of models can quantify global scale, land-use change scenarios, and there is large variance in the outcomes of these models (Alexander et al. 2016a ⁵⁰⁶ ; Prestele et al. 2016 ⁵⁰⁷ ). In some cases, there is greater variability between the models themselves than between the scenarios that they are quantifying, and these differences vary geographically (Prestele et al. 2016 ⁵⁰⁸ ). These differences arise from variations in baseline datasets, thematic classes and modelling paradigms (Alexander et al. 2016a ⁵⁰⁹ ; Popp et al. 2016 ⁵¹⁰ ; Prestele et al. 2016 ⁵¹¹ ). Model evaluation is critical in establishing confidence in the outcomes of modelled futures (Ahlstrom et al. 2012 ⁵¹² ; Kelley et al. 2013 ⁵¹³ ). Some, but not all, land-use models are evaluated against observational data and model evaluation is rarely reported. Hence, there is a need for more transparency in land-use modelling, especially in evaluation and testing, as well as making model code available with complete sets of scenario outputs (e.g., Dietrich et al. 2018 ⁵¹⁴ ).

There is a small, but growing literature on quantitative pathways to achieve normative visions and their associated trade-offs (IPBES 2018a ⁵¹⁵ ). Whilst the visions themselves may be clearly articulated, the societal choices, behaviours and transitions needed to attain them, are not. Better accounting for human behaviour and decision-making processes in global scale land-use models would improve the capacity to quantify pathways to sustainable futures (Rounsevell et al. 2014 ⁵¹⁶ ; Arneth et al. 2014 ⁵¹⁷ ; Calvin and Bond-Lamberty 2018 ⁵¹⁸ ). It is, however, difficult to understand and represent human behaviour and social interaction processes at global scales. Decision-making in global models is commonly represented through economic processes (Arneth et al. 2014 ⁵¹⁹ ). Other important human processes for land systems including equity, fairness, land tenure and the role of institutions and governance, receive less attention, and this limits the use of global models to quantify transformative pathways, adaptation and mitigation (Arneth et al. 2014 ⁵²⁰ ; Rounsevell et al. 2014 ⁵²¹ ; Wang et al. 2016 ^[[#fn:r|]] 522). No model exists at present to represent complex human behaviours at the global scale, although the need has been highlighted (Rounsevell et al. 2014 ⁵²³ ; Arneth et al. 2014 ⁵²⁴ ; Robinson et al. 2017 ⁵²⁵ ; Brown et al. 2017 ⁵²⁶ ; Calvin and Bond-Lamberty 2018 ⁵²⁷ ).

1.2.2.3 Uncertainties in decision-making

Decision-makers develop and implement policy in the face of many uncertainties (Rosenzweig and Neofotis 2013 ⁵²⁸ ; Anav et al. 2013 ⁵²⁹ ; Ciais et al. 2013a ⁵³⁰ ; Stocker et al. 2013b ⁵³¹ ) (Section 7.5). In context of climate change, the term ‘deep uncertainty’ is frequently used to denote situations in which either the analysis of a situation is inconclusive, or parties to a decision cannot agree on a number of criteria that would help to rank model results in terms of likelihood (e.g., Hallegatte and Mach 2016 ⁵³² ; Maier et al. 2016 ⁵³³ ) (Sections 7.1 and 7.5, and Table SM.1.2 in Supplementary Material). However, existing uncertainty does not support societal and political inaction.

The many ways of dealing with uncertainty in decision-making can be summarised by two decision approaches: (economic) cost-benefit analysis, and the precautionary approach. A typical variant of cost-benefit analysis is the minimisation of negative consequences. This approach needs reliable probability estimates (Gleckler et al. 2016 ⁵³⁴ ; Parker 2013 ⁵³⁵ ) and tends to focus on the short term. The precautionary approach does not take account of probability estimates (cf. Raffensperger and Tickner 1999 ⁵³⁶ ), but instead focuses on avoiding the worst outcome (Gardiner 2006 ⁵³⁷ ).

Between these two extremes, various decision approaches seek to address uncertainties in a more reflective manner that avoids the limitations of cost-benefit analysis and the precautionary approach. Climate-informed decision analysis combines various approaches to explore options and the vulnerabilities and sensitivities of certain decisions. Such an approach includes stakeholder involvement (e.g., elicitation methods), and can be combined with, for example, analysis of climate or land-use change modelling (Hallegatte and Rentschler 2015 ⁵³⁸ ; Luedeling and Shepherd 2016 ⁵³⁹ ).

Flexibility is facilitated by political decisions that are not set in stone and can change over time (Walker et al. 2013 ⁵⁴⁰ ; Hallegatte and Rentschler 2015 ⁵⁴¹ ). Generally, within the research community that investigates deep uncertainty, a paradigm is emerging that requires the development of a strategic vision of the long – or mid-term future, while committing to short-term actions and establishing a framework to guide future actions, including revisions and flexible adjustment of decisions (Haasnoot 2013 ⁵⁴² ) (Section 7.5).

1.3 Response options to the key challenges

A number of response options underpin solutions to the challenges arising from GHG emissions from land, and the loss of productivity arising from degradation and desertification. These options are discussed in Sections 2.5 and 6.2 and rely on (i) land management, (ii) value chain management, and (iii) risk management (Table 1.2). None of these response options are mutually exclusive, and it is their combination in a regionally, context-specific manner that is most likely to achieve co-benefits between climate change mitigation, adaptation and other environmental challenges in a cost-effective way (Griscom et al. 2017 ⁵⁴³ ; Kok et al. 2018 ⁵⁴⁴ ). Sustainable solutions affecting both demand and supply are expected to yield most co-benefits if these rely not only on the carbon footprint, but are extended to other vital ecosystems such as water, nutrients and biodiversity footprints (van Noordwijk and Brussaard 2014 ⁵⁴⁵ ; Cremasch 2016 ⁵⁴⁶ ). As an entry point to the discussion in Chapter 6, we introduce here a selected number of examples that cut across climate change mitigation, food security, desertification, and degradation issues, including potential trade-offs and co-benefits.

1.3.1 Targeted decarbonisation relying on large land-area need

Most global future scenarios that aim to achieve global warming of 2°C or well below rely on bioenergy (BE; BECCS, with carbon capture and storage; Cross-Chapter Box 7 in Chapter 6) or afforestation and reforestation (de Coninck et al. 2018 ⁵⁴⁷ ; Rogelj et al. 2018b ⁵⁴⁸ ,a ⁵⁴⁹ ; Anderson and Peters 2016 ⁵⁵⁰ ; Popp et al. 2016 ⁵⁵¹ ; Smith et al. 2016 ⁵⁵² ) (Cross-Chapter Box 2 in Chapter 1). In addition to the very large area requirements projected for 2050 or 2100, several other aspects of these scenarios have also been criticised. For instance, they simulate very rapid technological and societal uptake rates for the land-related mitigation measures, when compared with historical observations (Turner et al. 2018 ⁵⁵³ ; Brown et al. 2019 ⁵⁵⁴ ; Vaughan and Gough 2016 ⁵⁵⁵ ). Furthermore, confidence in the projected bioenergy or BECCS net carbon uptake potential is low , because of many diverging assumptions. This includes assumptions about bioenergy crop yields, the possibly large energy demand for CCS, which diminishes the net-GHG-saving of bioenergy systems, or the incomplete accounting for ecosystem processes and of the cumulative carbon-loss arising from natural vegetation clearance for bioenergy crops or bioenergy forests and subsequent harvest regimes (Anderson and Peters 2016 ⁵⁵⁶ ; Bentsen 2017 ⁵⁵⁷ ; Searchinger et al. 2017 ⁵⁵⁸ ; Bayer et al. 2017 ⁵⁵⁹ ; Fuchs et al. 2017 ⁵⁶⁰ ; Pingoud et al. 2018 ⁵⁶¹ ; Schlesinger 2018 ⁵⁶² ). Bioenergy provision under politically unstable conditions may also be a problem (Erb et al. 2012 ⁵⁶³ ; Searle and Malins 2015 ⁵⁶⁴ ).

Large-scale bioenergy plantations and forests may compete for the same land area (Harper et al. 2018 ⁵⁶⁵ ). Both potentially have adverse side effects on biodiversity and ecosystem services, as well as socio-economic trade-offs such as higher food prices due to land-area competition (Shi et al. 2013 ⁵⁶⁶ ; Bárcena et al. 2014 ⁵⁶⁷ ; Fernandez-Martinez et al. 2014 ⁵⁶⁸ ; Searchinger et al. 2015 ⁵⁶⁹ ; Bonsch et al. 2016 ⁵⁷⁰ ; Creutzig et al. 2015 ⁵⁷¹ ; Kreidenweis et al. 2016 ⁵⁷² ; Santangeli et al. 2016 ⁵⁷³ ; Williamson 2016 ⁵⁷⁴ ; Graham et al. 2017 ⁵⁷⁵ ; Krause et al. 2017 ⁵⁷⁶ ; Hasegawa et al. 2018 ⁵⁷⁷ ; Humpenoeder et al. 2018 ⁵⁷⁸ ). Although forest-based mitigation could have co-benefits for biodiversity and many ecosystem services, this depends on the type of forest planted and the vegetation cover it replaces (Popp et al. 2014 ⁵⁷⁹ ; Searchinger et al. 2015 ⁵⁸⁰ ) (Cross-Chapter Box 2 in Chapter 1).

There is high confidence that scenarios with large land requirements for climate change mitigation may not achieve SDGs, such as no poverty, zero hunger and life on land, if competition for land and the need for agricultural intensification are greatly enhanced (Creutzig et al. 2016 ⁵⁸¹ ; Dooley and Kartha 2018 ⁵⁸² ; Hasegawa et al. 2015 ⁵⁸³ ; Hof et al. 2018 ⁵⁸⁴ ; Roy et al. 2018 ⁵⁸⁵ ; Santangeli et al. 2016 ⁵⁸⁶ ; Boysen et al. 2017 ⁵⁸⁷ ; Henry et al. 2018 ⁵⁸⁸ ; Kreidenweis et al. 2016 ⁵⁸⁹ ; UN 2015 ⁵⁹⁰ ). This does not mean that smaller-scale land-based climate mitigation could not have positive outcomes for then achieving these goals (e.g., Sections 6.2, and 4.5, Cross-Chapter Box 7 in Chapter 6).

CCB2 Implications of large-scale conversion from non-forest to forest land

Baldur Janz (Germany), Almut Arneth (Germany), Francesco Cherubini (Norway/Italy), Edouard Davin (Switzerland/France), Aziz Elbehri (Morocco), Kaoru Kitajima (Japan), Werner Kurz (Canada). Efforts to increase forest area While deforestation continues in many world regions, especially in the tropics, large expansion of mostly managed forest area has taken place in some countries. In the IPCC context, reforestation (conversion to forest of land that previously contained forests but has been converted to some other use) is distinguished from afforestation (conversion to forest of land that historically has not contained forests; see Glossary). Past expansion of managed forest area occurred in many world-regions for a variety of reasons, from meeting needs for wood fuel or timber (Vadell et al. 2016 591 ; Joshi et al. 2011 592 ; Zaloumis and Bond 2015 593 ; Payn et al. 2015 594 ; Shoyama 2008 595 ; Miyamoto et al. 2011 596 ) to restoration-driven efforts, with the aim of enhancing ecological function (Filoso et al. 2017 597 ; Salvati and Carlucci 2014 598 ; Ogle et al. 2018 599 ; Crouzeilles et al. 2016 600 ; FAO 2016 601 ) (Sections 3.7 and 4.9). In many regions, net forest area increase includes deforestation (often of native forests) alongside increasing forest area (often managed forest, but also more natural forest restoration efforts) (Heilmayr et al. 2016 602 ; Scheidel and Work 2018 603 ; Hua et al. 2018 604 ; Crouzeilles et al. 2016 605 ; Chazdon et al. 2016b 606 ). China and India have seen the largest net forest area increase, aiming to alleviate soil erosion, desertification and overgrazing (Ahrends et al. 2017 607 ; Cao et al. 2016 608 ; Deng et al. 2015 609 ; Chen et al. 2019 610 ) (Sections 3.7 and 4.9) but uncertainties in exact forest area changes remain large, mostly due to differences in methodology and forest classification (FAO 2015a 611 ; Song et al. 2018 612 ; Hansen et al. 2013 613 ; MacDicken et al. 2015 614 ). What are the implications for ecosystems? 1. Implications for biogeochemical and biophysical processes There is robust evidence and medium agreement that whilst forest area expansion increases ecosystem carbon storage, the magnitude of the increased stock depends on the type and length of former land use, forest type planted, and climatic regions (Bárcena et al. 2014 615 ; Poeplau et al. 2011 616 ; Shi et al. 2013 617 ; Li et al. 2012 618 ) (Section 4.3). While reforestation of former croplands increases net ecosystem carbon storage (Bernal et al. 2018 619 ; Lamb 2018 620 ), afforestation on native grassland results in reduction of soil carbon stocks, which can reduce or negate the net carbon benefits which are dominated by increases in biomass, dead wood and litter carbon pools (Veldman et al. 2015, 2017 621 ). Forest vs non-forest lands differ in land surface reflectiveness of shortwave radiation and evapotranspiration (Anderson et al. 2011 622 ; Perugini et al. 2017 623 ) (Section 2.4). Evapotranspiration from forests during the growing season regionally cools the land surface and enhances cloud cover that reduces shortwave radiation reaching the land, an impact that is especially pronounced in the tropics. However, dark evergreen conifer-dominated forests have low surface reflectance, and tend to cause warming of the near-surface atmosphere compared to non-forest land, especially when snow cover is present such as in boreal regions (Duveiller et al. 2018 624 ; Alkama and Cescatti 2016 625 ; Perugini et al. 2017 626 ) (medium evidence, high agreement). 2. Implications for water balance Evapotranspiration by forests reduces surface runoff and erosion of soil and nutrients (Salvati et al. 2014 627 ). Planting of fast-growing species in semi-arid regions or replacing natural grasslands with forest plantations can divert soil water resources to evapotranspiration from groundwater recharge (Silveira et al. 2016 628 ; Zheng et al. 2016 629 ; Cao et al. 2016 630 ). Multiple cases are reported from China where afforestation programs, some with irrigation, without having been tailored to local precipitation conditions, resulted in water shortages and tree mortality (Cao et al. 2016; Yang et al. 2014 631 ; Li et al. 2014 632 ; Feng et al. 2016 633 ). Water shortages may create long-term water conflicts (Zheng et al. 2016 634 ). However, reforestation (in particular for restoration) is also associated with improved water filtration, groundwater recharge (Ellison et al. 2017 635 ) and can reduce risk of soil erosion, flooding, and associated disasters (Lee et al. 2018 636 ) (Section 4.9). 3. Implications for biodiversity Impacts of forest area expansion on biodiversity depend mostly on the vegetation cover that is replaced: afforestation on natural non-tree-dominated ecosystems can have negative impacts on biodiversity (Abreu et al. 2017 637 ; Griffith et al. 2017 638 ; Veldman et al. 2015 639 ; Parr et al. 2014 640 ; Wilson et al. 2017 641 ; Hua et al. 2016 642 ; see also IPCC 1.5° report (2018)). Reforestation with monocultures of fast-growing, non-native trees has little benefit to biodiversity (Shimamoto et al. 2018 643 ; Hua et al. 2016). There are also concerns regarding some commonly used plantation species (e.g., Acacia and Pinus species) to become invasive (Padmanaba and Corlett 2014 644 ; Cunningham et al. 2015b 645 ).

Reforestation with mixes of native species, especially in areas that retain fragments of native forest, can support ecosystem services and biodiversity recovery, with positive social and environmental co-benefits (Cunningham et al. 2015a ⁶⁴⁶ ; Dendy et al. 2015 ⁶⁴⁷ ; Chaudhary and Kastner 2016 ⁶⁴⁸ ; Huang et al. 2018 ⁶⁴⁹ ; Locatelli et al. 2015b ⁶⁵⁰ ) (Section 4.5). Even though species diversity in re-growing forests is typically lower than in primary forests, planting native or mixed species can have positive effects on biodiversity (Brockerhoff et al. 2013 ⁶⁵¹ ; Pawson et al. 2013 ⁶⁵² ; Thompson et al. 2014 ⁶⁵³ ). Reforestation has been shown to improve links among existing remnant forest patches, increasing species movement, and fostering gene flow between otherwise isolated populations (Gilbert-Norton et al. 2010 ⁶⁵⁴ ; Barlow et al. 2007 ⁶⁵⁵ ; Lindenmayer and Hobbs 2004 ⁶⁵⁶ ).

4. Implications for other ecosystem services and societies

Forest area expansion could benefit recreation and health, preservation of cultural heritage and local values and knowledge, livelihood support (via reduced resource conflicts, restoration of local resources). These social benefits could be most successfully achieved if local communities’ concerns are considered (Le et al. 2012 ⁶⁵⁷ ). However, these co-benefits have rarely been assessed due to a lack of suitable frameworks and evaluation tools (Baral et al. 2016 ⁶⁵⁸ ).

Industrial forest management can be in conflict with the needs of forest-dependent people and community-based forest management over access to natural resources (Gerber 2011 ⁶⁵⁹ ; Baral et al. 2016 ⁶⁶⁰ ) and/or loss of customary rights over land use (Malkamäki et al. 2018 ⁶⁶¹ ; Cotula et al. 2014 ⁶⁶² ). A common result is out-migration from rural areas and diminishing local uses of ecosystems (Gerber 2011 ⁶⁶³ ). Policies promoting large-scale tree plantations gain traction if these are reappraised in view of potential co-benefits with several ecosystem services and local societies (Bull et al. 2006 ⁶⁶⁴ ; Le et al. 2012 ⁶⁶⁵ ).

Scenarios of forest area expansion for land-based climate change mitigation

Conversion of non-forest to forest land has been discussed as a relatively cost-effective climate change mitigation option when compared to options in the energy and transport sectors (medium evidence, medium agreement) (de Coninck et al. 2018 ⁶⁶⁶ ; Griscom et al. 2017 ⁶⁶⁷ ; Fuss et al. 2018 ⁶⁶⁸ ), and can have co-benefits with adaptation.

Sequestration of CO ₂ from the atmosphere through forest area expansion has become a fundamental part of stringent climate change mitigation scenarios (Rogelj et al. 2018a ⁶⁶⁹ ; Fuss et al. 2018 ⁶⁷⁰ ) (e.g., Sections 2.5, 4.5 and 6.2). The estimated mitigation potential ranges from about 0.5 to 10 GtCO ₂ yr–1 (robust evidence, medium agreement), and depends on assumptions regarding available land and forest carbon uptake potential (Houghton 2013 ⁶⁷¹ ; Houghton and Nassikas 2017 ⁶⁷² ; Griscom et al. 2017 ⁶⁷³ ; Lenton 2014 ⁶⁷⁴ ; Fuss et al. 2018 ⁶⁷⁵ ; Smith 2016 ⁶⁷⁶ ) (Section 2.5.1). In climate change mitigation scenarios, typically, no differentiation is made between reforestation and afforestation despite different overall environmental impacts between these two measures. Likewise, biodiversity conservation, impacts on water balances, other ecosystem services, or land-ownership – as constraints when simulating forest area expansion (Cross-Chapter Box 1 in Chapter 1) – tend not to be included as constraints when simulating forest area expansion.

Projected forest area increases, relative to today’s forest area, range from approximately 25% in 2050 and increase to nearly 50% by 2100 (Rogelj et al. 2018a ⁶⁷⁷ ; Kreidenweis et al. 2016 ⁶⁷⁸ ; Humpenoder et al. 2014 ⁶⁷⁹ ). Potential adverse side-effects of such large-scale measures, especially for low-income countries, could be increasing food prices from the increased competition for land (Kreidenweis et al. 2016 ⁶⁸⁰ ; Hasegawa et al. 2015 ⁶⁸¹ , 2018 ⁶⁸² ; Boysen et al. 2017 ⁶⁸³ ) (Section 5.5). Forests also emit large amounts of biogenic volatile compounds that under some conditions contribute to the formation of atmospherically short-lived climate forcing compounds, which are also detrimental to health (Ashworth et al. 2013 ⁶⁸⁴ ; Harrison et al. 2013 ⁶⁸⁵ ). Recent analyses argued for an upper limit of about 5 million km2 of land globally available for climate change mitigation through reforestation, mostly in the tropics (Houghton 2013 ⁶⁸⁶ ) – with potential regional co-benefits.

Since forest growth competes for land with bioenergy crops (Harper et al. 2018 ⁶⁸⁷ ) (Cross-Chapter Box 7 in Chapter 6), global area estimates need to be assessed in light of alternative mitigation measures at a given location. In all forest-based mitigation efforts, the sequestration potential will eventually saturate unless the area keeps expanding, or harvested wood is either used for long-term storage products or for carbon capture and storage (Fuss et al. 2018 ⁶⁸⁸ ; Houghton et al. 2015 ⁶⁸⁹ ) (Section 2.5.1). Considerable uncertainty in forest carbon uptake estimates is further introduced by potential forest losses from fire or pest outbreaks (Allen et al. 2010 ⁶⁹⁰ ; Anderegg et al. 2015 ⁶⁹¹ ) (Cross-Chapter Box 3 in Chapter 2). And like all land-based mitigation measures, benefits may be diminshed by land-use displacement, and through trade of land-based products, especially in poor countries that experience forest loss (e.g., Africa) (Bhojvaid et al. 2016 ⁶⁹² ; Jadin et al. 2016 ⁶⁹³ ).

Conclusion

Reforestation is a mitigation measure with potential co-benefits for conservation and adaptation, including biodiversity habitat, air and water filtration, flood control, enhanced soil fertility and reversal of land degradation. Potential adverse side-effects of forest area expansion depend largely on the state of the land it displaces as well as tree species selections. Active governance and planning contribute to maximising co-benefits while minimising adverse side-effects (Laestadius et al. 2011 ⁶⁹⁴ ; Dinerstein et al. 2015 ⁶⁹⁵ ; Veldman et al. 2017 ⁶⁹⁶ ) (Section 4.8 and Chapter 7). At large spatial scales, forest expansion is expected to lead to increased competition for land, with potentially undesirable impacts on food prices, biodiversity, non-forest ecosystems and water availability (Bryan and Crossman 2013 ⁶⁹⁷ ; Boysen et al. 2017 ⁶⁹⁸ ; Kreidenweis et al. 2016 ⁶⁹⁹ ; Egginton et al. 2014 ⁷⁰⁰ ; Cao et al. 2016 ⁷⁰¹ ; Locatelli et al. 2015a ⁷⁰² ; Smith et al. 2013 ⁷⁰³ ).

1.3.2 Land management

1.3.2.1 Agricultural, forest and soil management

Sustainable land management (SLM) describes “the stewardship and use of land resources, including soils, water, animals and plants, to meet changing human needs while simultaneously assuring the long-term productive potential of these resources and the maintenance of their environmental functions” (Alemu 2016 ⁷⁰⁴ ; Altieri and Nicholls 2017 ⁷⁰⁵ ) (e.g., Section 4.1.5), and includes ecological, technological and governance aspects.

The choice of SLM strategy is a function of regional context and land-use types, with high agreement on (a combination of) choices such as agroecology (including agroforestry), conservation agriculture and forestry practices, crop and forest species diversity, appropriate crop and forest rotations, organic farming, integrated pest management, the preservation and protection of pollination services, rainwater harvesting, range and pasture management, and precision agriculture systems (Stockmann et al. 2013 ⁷⁰⁶ ; Ebert, 2014 ⁷⁰⁷ ; Schulte et al. 2014 ⁷⁰⁸ ; Zhang et al. 2015 ⁷⁰⁹ ; Sunil and Pandravada 2015 ⁷¹⁰ ; Poeplau and Don 2015 ⁷¹¹ ; Agus et al. 2015 ⁷¹² ; Keenan 2015 ⁷¹³ ; MacDicken et al. 2015 ⁷¹⁴ ; Abberton et al. 2016 ⁷¹⁵ ). Conservation agriculture and forestry uses management practices with minimal soil disturbance such as no tillage or minimum tillage, permanent soil cover with mulch, combined with rotations to ensure a permanent soil surface, or rapid regeneration of forest following harvest (Hobbs et al. 2008 ⁷¹⁶ ; Friedrich et al. 2012 ⁷¹⁷ ). Vegetation and soils in forests and woodland ecosystems play a crucial role in regulating critical ecosystem processes, therefore reduced deforestation together with sustainable forest management are integral to SLM (FAO 2015b ⁷¹⁸ ) (Section 4.8). In some circumstances, increased demand for forest products can also lead to increased management of carbon storage in forests (Favero and Mendelsohn 2014 ⁷¹⁹ ). Precision agriculture is characterised by a “management system that is information and technology based, is site specific and uses one or more of the following sources of data: soils, crops, nutrients, pests, moisture, or yield, for optimum profitability, sustainability, and protection of the environment” (USDA 2007 ⁷²⁰ ) (Cross-Chapter Box 6 in Chapter 5). The management of protected areas that reduce deforestation also plays an important role in climate change mitigation and adaptation while delivering numerous ecosystem services and sustainable development benefits (Bebber and Butt 2017 ⁷²¹ ). Similarly, when managed in an integrated and sustainable way, peatlands are also known to provide numerous ecosystem services, as well as socio-economic and mitigation and adaptation benefits (Ziadat et al. 2018 ⁷²² ).

Biochar is an organic compound used as soil amendment and is believed to be potentially an important global resource for mitigation. Enhancing the carbon content of soil and/or use of biochar (Chapter 4) have become increasingly important as a climate change mitigation option with possibly large co-benefits for other ecosystem services. Enhancing soil carbon storage and the addition of biochar can be practiced with limited competition for land, provided no productivity/ yield loss and abundant unused biomass, but evidence is limited and impacts of large scale application of biochar on the full GHG balance of soils, or human health are yet to be explored (Gurwick et al. 2013 ⁷²³ ; Lorenz and Lal 2014 ⁷²⁴ ; Smith 2016 ⁷²⁵ ).

1.3.3 Value chain management

1.3.3.1 Supply management

Food losses from harvest to retailer. Approximately one-third of losses and waste in the food system occurs between crop production and food consumption, increasing substantially if losses in livestock production and overeating are included (Gustavsson et al. 2011 ⁷²⁶ ; Alexander et al. 2017 ⁷²⁷ ). This includes on-farm losses, farm to retailer losses, as well retailer and consumer losses (Section 1.3.3.2).

Post-harvest food loss – on farm and from farm to retailer – is a widespread problem, especially in developing countries (Xue et al. 2017 ⁷²⁸ ), but are challenging to quantify. For instance, averaged for eastern and southern Africa an estimated 10–17% of annual grain production is lost (Zorya et al. 2011 ⁷²⁹ ). Across 84 countries and different time periods, annual median losses in the supply chain before retailing were estimated at about 28 kg per capita for cereals or about 12 kg per capita for eggs and dairy products (Xue et al. 2017 ⁷³⁰ ). For the year 2013, losses prior to the reaching retailers were estimated at 20% (dry weight) of the production amount (22% wet weight) (Gustavsson et al. 2011 ⁷³¹ ; Alexander et al. 2017 ⁷³² ). While losses of food cannot be realistically reduced to zero, advancing harvesting technologies (Bradford et al. 2018 ⁷³³ ; Affognon et al. 2015 ⁷³⁴ ), storage capacity (Chegere 2018 ⁷³⁵ ) and efficient transportation could all contribute to reducing these losses with co-benefits for food availability, the land area needed for food production and related GHG emissions.

Stability of food supply, transport and distribution. Increased climate variability enhances fluctuations in world food supply and price variability (Warren 2014 ⁷³⁶ ; Challinor et al. 2015 ⁷³⁷ ; Elbehri et al. 2017 ⁷³⁸ ). ‘Food price shocks’ need to be understood regarding their transmission across sectors and borders and impacts on poor and food insecure populations, including urban poor subject to food deserts and inadequate food accessibility (Widener et al. 2017 ⁷³⁹ ; Lehmann et al. 2013 ⁷⁴⁰ ; Le 2016 ⁷⁴¹ ; FAO 2015b ⁷⁴² ). Trade can play an important stabilising role in food supply, especially for regions with agro-ecological limits to production, including water scarce regions, as well as regions that experience short-term production variability due to climate, conflicts or other economic shocks (Gilmont 2015 ⁷⁴³ ; Marchand et al. 2016 ⁷⁴⁴ ). Food trade can either increase or reduce the overall environmental impacts of agriculture (Kastner et al. 2014 ⁷⁴⁵ ). Embedded in trade are virtual transfers of water, land area, productivity, ecosystem services, biodiversity, or nutrients (Marques et al. 2019 ⁷⁴⁶ ; Wiedmann and Lenzen 2018 ⁷⁴⁷ ; Chaudhary and Kastner 2016 ⁷⁴⁸ ) with either positive or negative implications (Chen et al. 2018 ⁷⁴⁹ ; Yu et al. 2013 ⁷⁵⁰ ). Detrimental consequences in countries in which trade dependency may accentuate the risk of food shortages from foreign production shocks could be reduced by increasing domestic reserves or importing food from a diversity of suppliers (Gilmont 2015 ⁷⁵¹ ; Marchand et al. 2016 ⁷⁵² ).

Climate mitigation policies could create new trade opportunities (e.g., biomass) (Favero and Massetti 2014 ⁷⁵³ ) or alter existing trade patterns. The transportation GHG footprints of supply chains may be causing a differentiation between short and long supply chains (Schmidt et al. 2017 ⁷⁵⁴ ) that may be influenced by both economics and policy measures (Section 5.4). In the absence of sustainable practices and when the ecological footprint is not valued through the market system, trade can also exacerbate resource exploitation and environmental leakages, thus weakening trade mitigation contributions (Dalin and Rodríguez-Iturbe 2016 ⁷⁵⁵ ; Mosnier et al. 2014 ⁷⁵⁶ ; Elbehri et al. 2017 ⁷⁵⁷ ). Ensuring stable food supply while pursuing climate mitigation and adaptation will benefit from evolving trade rules and policies that allow internalisation of the cost of carbon (and costs of other vital resources such as water, nutrients). Likewise, future climate change mitigation policies would gain from measures designed to internalise the environmental costs of resources and the benefits of ecosystem services (Elbehri et al. 2017 ⁷⁵⁸ ; Brown et al. 2007 ⁷⁵⁹ ).

1.3.3.2 Demand management

Dietary change. Demand-side solutions to climate mitigation are an essential complement to supply-side, technology and productivity driven solutions ( high confidence ) (Creutzig et al. 2016 ⁷⁶⁰ ; Bajželj et al. 2014 ⁷⁶¹ ; Erb et al. 2016b ⁷⁶² ; Creutzig et al. 2018 ⁷⁶³ ) (Sections 5.5.1 and 5.5.2). The environmental impacts of the animal-rich ‘western diets’ are being examined critically in the scientific literature (Hallström et al. 2015 ⁷⁶⁴ ; Alexander et al. 2016b ⁷⁶⁵ ; Alexander et al. 2015 ⁷⁶⁶ ; Tilman and Clark 2014 ⁷⁶⁷ ; Aleksandrowicz et al. 2016 ⁷⁶⁸ ; Poore and Nemecek 2018 ⁷⁶⁹ ) (Section 5.4.6). For example, if the average diet of each country were consumed globally, the agricultural land area needed to supply these diets would vary 14-fold, due to country differences in ruminant protein and calorific intake (–55% to +178% compared to existing cropland areas). Given the important role enteric fermentation plays in methane (CH4) emissions, a number of studies have examined the implications of lower animal-protein diets (Swain et al. 2018 ⁷⁷⁰ ; Röös et al. 2017 ⁷⁷¹ ; Rao et al. 2018 ⁷⁷² ). Reduction of animal protein intake has been estimated to reduce global green water (from precipitation) use by 11% and blue water (from rivers, lakes, groundwater) use by 6% (Jalava et al. 2014 ⁷⁷³ ). By avoiding meat from producers with above-median GHG emissions and halving animal-product intake, consumption change could free-up 21 million km ² of agricultural land and reduce GHG emissions by nearly 5 GtCO ₂ -eq yr ^–1 or up to 10.4 GtCO ₂ -eq yr ^–1 when vegetation carbon uptake is considered on the previously agricultural land (Poore and Nemecek 2018 ⁷⁷⁴ , 2019).

Diets can be location and community specific, are rooted in culture and traditions while responding to changing lifestyles driven for instance by urbanisation and changing income. Changing dietary and consumption habits would require a combination of non-price (government procurement, regulations, education and awareness raising) and price incentives (Juhl and Jensen 2014 ⁷⁷⁵ ) to induce consumer behavioural change with potential synergies between climate, health and equity (addressing growing global nutrition imbalances that emerge as undernutrition, malnutrition, and obesity) (FAO 2018b ⁷⁷⁶ ).

Reduced waste and losses in the food demand system. Global averaged per capita food waste and loss (FWL) have increased by 44% between 1961 and 2011 (Porter et al. 2016 ⁷⁷⁷ ) and are now around 25–30% of global food produced (Kummu et al. 2012 ⁷⁷⁸ ; Alexander et al. 2017 ⁷⁷⁹ ). Food waste occurs at all stages of the food supply chain from the household to the marketplace (Parfitt et al. 2010 ⁷⁸⁰ ) and is found to be larger at household than at supply chain levels. A meta-analysis of 55 studies showed that the highest share of food waste was at the consumer stage (43.9% of total) with waste increasing with per capita GDP for high-income countries until a plateaux at about 100 kg cap ^–1 yr ^–1 (around 16% of food consumption) above about 70,000 USD cap ^–1 (van der Werf and Gilliland 2017 ⁷⁸¹ ; Xue et al. 2017 ⁷⁸² ). Food loss from supply chains tends to be more prevalent in less developed countries where inadequate technologies, limited infrastructure, and imperfect markets combine to raise the share of the food production lost before use.

There are several causes behind food waste including economics (cheap food), food policies (subsidies) as well as individual behaviour (Schanes et al. 2018 ⁷⁸³ ). Household level food waste arises from overeating or overbuying (Thyberg and Tonjes 2016 ⁷⁸⁴ ). Globally, overconsumption was found to waste 9–10% of food bought (Alexander et al. 2017 ⁷⁸⁵ ).

Solutions to FWL thus need to address technical and economic aspects. Such solutions would benefit from more accurate data on the loss-source, loss-magnitude and causes along the food supply chain. In the long run, internalising the cost of food waste into the product price would more likely induce a shift in consumer behaviour towards less waste and more nutritious, or alternative, food intake (FAO 2018b ⁷⁸⁶ ). Reducing FWL would bring a range of benefits for health, reducing pressures on land, water and nutrients, lowering emissions and safeguarding food security. Reducing food waste by 50% would generate net emissions reductions in the range of 20 to 30% of total food-sourced GHGs (Bajželj et al. 2014 ⁷⁸⁷ ). SDG 12 (“Ensure sustainable consumption and production patterns”) calls for per capita global food waste to be reduced by one-half at the retail and consumer level, and reducing food losses along production and supply chains by 2030.

1.3.4 Risk management

Risk management refers to plans, actions, strategies or policies to reduce the likelihood and/or magnitude of adverse potential consequences, based on assessed or perceived risks. Insurance and early warning systems are examples of risk management, but risk can also be reduced (or resilience enhanced) through a broad set of options ranging from seed sovereignty, livelihood diversification, to reducing land loss through urban sprawl. Early warning systems support farmer decision-making on management strategies (Section 1.2) and are a good example of an adaptation measure with mitigation co-benefits such as reducing carbon losses (Section 1.3.6). Primarily designed to avoid yield losses, early warning systems also support fire management strategies in forest ecosystems, which prevents financial as well as carbon losses (de Groot et al. 2015 ⁷⁸⁸ ). Given that over recent decades on average around 10% of cereal production was lost through extreme weather events (Lesk et al. 2016 ⁷⁹⁰ ), where available and affordable, insurance can buffer farmers and foresters against the financial losses incurred through such weather and other (fire, pests) extremes (Falco et al. 2014 ⁷⁹¹ ) (Sections 7.2 and 7.4). Decisions to take up insurance are influenced by a range of factors such as the removal of subsidies or targeted education (Falco et al. 2014). Enhancing access and affordability of insurance in low-income countries is a specific objective of the UNFCCC (Linnerooth-Bayer and Mechler 2006 ⁷⁹² ). A global mitigation co-benefit of insurance schemes may also include incentives for future risk reduction (Surminski and Oramas-Dorta 2014 ⁷⁹³ ).

1.3.5 Economics of land-based mitigation pathways: Costs versus benefits of early action under uncertainty

The overarching societal costs associated with GHG emissions and the potential implications of mitigation activities can be measured by various metrics (cost-benefit analysis, cost effectiveness analysis) at different scales (project, technology, sector or the economy) (IPCC 2018 ⁷⁹⁴ ) (Section 1.4). The social cost of carbon (SCC) measures the total net damages of an extra metric tonne of CO ₂  emissions due to the associated climate change (Nordhaus 2014 ⁷⁹⁵ ; Pizer et al. 2014 ⁷⁹⁶ ). Both negative and positive impacts are monetised and discounted to arrive at the net value of consumption loss. As the SCC depends on discount rate assumptions and value judgements (e.g., relative weight given to current vs future generations), it is not a straightforward policy tool to compare alternative options. At the sectoral level, marginal abatement cost curves (MACCs) are widely used for the assessment  of costs related to GHG emissions reduction. MACCs measure the cost of reducing one more GHG unit and are either expert-based or model-derived and offer a range of approaches and assumptions on discount rates or available abatement technologies (Kesicki 2013 ⁷⁹⁷ ). In land-based sectors, Gillingham and Stock (2018) ⁷⁹⁸ reported short-term static abatement costs for afforestation of between 1 and 10 USD2017 per tCO ₂ , soil management at 57 and livestock management at 71 USD2017 per tCO ₂ . MACCs are more reliable when used to rank alternative options compared to a baseline (or business as usual) rather than offering absolute numerical measures (Huang et al. 2016 ⁷⁹⁹ ). The economics of land-based mitigation options encompass also the “costs of inaction” that arise either from the economic damages due to continued accumulation of GHGs in the atmosphere and from the diminution in value of ecosystem services or the cost of their restoration where feasible (Rodriguez-Labajos 2013 ⁸⁰⁰ ; Ricke et al. 2018 ⁸⁰¹ ). Overall, it remains challenging to estimate the costs of alternative mitigation options owing to the context – and scale-specific interplay between multiple drivers (technological, economic, and socio-cultural) and enabling policies and institutions (IPCC 2018 ⁸⁰² ) (Section 1.4).

The costs associated with mitigation (both project-linked such as capital costs or land rental rates, or sometimes social costs) generally increase with stringent mitigation targets and over time. Sources of uncertainty include the future availability, cost and performance of technologies (Rosen and Guenther 2015 ⁸⁰³ ; Chen et al. 2016 ⁸⁰⁴ ) or lags in decision-making, which have been demonstrated by the uptake of land use and land utilisation policies (Alexander et al. 2013 ⁸⁰⁵ ; Hull et al. 2015 ⁸⁰⁶ ; Brown et al. 2018b ⁸⁰⁷ ). There is growing evidence of significant mitigation gains through conservation, restoration and improved land management practices (Griscom et al. 2017 ⁸⁰⁸ ; Kindermann et al. 2008 ⁸⁰⁹ ; Golub et al. 2013 ⁸¹⁰ ; Favero et al. 2017 ⁸¹¹ ) (Chapters 4 and 6), but the mitigation cost efficiency can vary according to region and specific ecosystem (Albanito et al. 2016 ⁸¹² ). Recent model developments that treat process-based, human–environment interactions have recognised feedbacks that reinforce or dampen the original stimulus for land-use change (Robinson et al. 2017 ⁸¹³ ; Walters and Scholes 2017 ⁸¹⁴ ). For instance, land mitigation interventions that rely on large-scale, land-use change (e.g., afforestation) would need to account for the rebound effect (which dampens initial impacts due to feedbacks) in which raising land prices also raises the cost of land-based mitigation (Vivanco et al. 2016 ⁸¹⁵ ). Although there are few direct estimates, indirect assessments strongly point to much higher costs if action is delayed or limited in scope ( medium confidence ). Quicker response options are also needed to avoid loss of high-carbon ecosystems and other vital ecosystem services that provide multiple services that are difficult to replace (peatlands, wetlands, mangroves, forests) (Yirdaw et al. 2017 ⁸¹⁶ ; Pedrozo-Acuña et al. 2015 ⁸¹⁷ ). Delayed action would raise relative costs in the future or could make response options less feasible ( medium confidence ) (Goldstein et al. 2019 ⁸¹⁸ ; Butler et al. 2014 ⁸¹⁹ ).

1.3.6 Adaptation measures and scope for co-benefits with mitigation

Adaptation and mitigation have generally been treated as two separate discourses, both in policy and practice, with mitigation addressing cause and adaptation dealing with the consequences of climate change (Hennessey et al. 2017 ⁸²⁰ ). While adaptation (e.g., reducing flood risks) and mitigation (e.g., reducing non-CO ₂ emissions from agriculture) may have different objectives and operate at different scales, they can also generate joint outcomes (Locatelli et al. 2015b ⁸²¹ ) with adaptation generating mitigation co-benefits. Seeking to integrate strategies for achieving adaptation and mitigation goals is attractive in order to reduce competition for limited resources and trade-offs (Lobell et al. 2013 ⁸²² ; Berry et al. 2015 ⁸²³ ; Kongsager and Corbera 2015 ⁸²⁴ ). Moreover, determinants that can foster adaptation and mitigation practices are similar. These tend to include available technology and resources, and credible information for policymakers to act on (Yohe 2001 ⁸²⁵ ).

Four sets of mitigation–adaptation interrelationships can be distinguished: (i) mitigation actions that can result in adaptation benefits; (ii) adaptation actions that have mitigation benefits; (iii) processes that have implications for both adaptation and mitigation; and (iv) strategies and policy processes that seek to promote an integrated set of responses for both adaptation and mitigation (Klein et al. 2007). A high level of adaptive capacity is a key ingredient to developing successful mitigation policy. Implementing mitigation action can result in increasing resilience especially if it is able to reduce risks. Yet, mitigation and adaptation objectives, scale of implementation, sector and even metrics to identify impacts tend to differ (Ayers and Huq 2009 ⁸²⁶ ), and institutional setting, often does not enable an environment where synergies are sought (Kongsager et al. 2016 ⁸²⁷ ). Trade-offs between adaptation and mitigation exist as well and need to be understood (and avoided) to establish win-win situations (Porter et al. 2014 ⁸²⁸ ; Kongsager et al. 2016 ⁸²⁹ ).

Forestry and agriculture offer a wide range of lessons for the integration of adaptation and mitigation actions given the vulnerability of forest ecosystems or cropland to climate variability and change (Keenan 2015 ⁸³⁰ ; Gaba et al. 2015 ⁸³¹ ) (Sections 5.6 and 4.8). Increasing adaptive capacity in forested areas has the potential to prevent deforestation and forest degradation (Locatelli et al. 2011 ⁸³² ). Reforestation projects, if well managed, can increase community economic opportunities that encourage conservation (Nelson and de Jong 2003 ⁸³³ ), build capacity through training of farmers and installation of multifunctional plantations with income generation (Reyer et al. 2009 ⁸³⁴ ), strengthen local institutions (Locatelli et al. 2015a ⁸³⁵ ) and increase cash-flow to local forest stakeholders from foreign donors (West 2016 ⁸³⁶ ). A forest plantation that sequesters carbon for mitigation can also reduce water availability to downstream populations and heighten their vulnerability to drought. Inversely, not recognising mitigation in adaptation projects may yield adaptation measures that increase greenhouse gas emissions, a prime example of ‘maladaptation’. Analogously, ‘mal-mitigation’ would result in reducing GHG emissions, but increasing vulnerability (Barnett and O’Neill 2010 ⁸³⁷ ; Porter et al. 2014 ⁸³⁸ ). For instance, the cost of pursuing large-scale adaptation and mitigation projects has been associated with higher failure risks, onerous transactions costs and the complexity of managing big projects (Swart and Raes 2007 ⁸³⁹ ).

Adaptation encompasses both biophysical and socio-economic vulnerability and underlying causes (informational, capacity, financial, institutional, and technological; Huq et al. 2014 ⁸⁴⁰ ) and it is increasingly linked to resilience and to broader development goals (Huq et al. 2014 ⁸⁴¹ ). Adaptation measures can increase performance of mitigation projects under climate change and legitimise mitigation measures through the more immediately felt effects of adaptation (Locatelli et al. 2011 ⁸⁴² ; Campbell et al. 2014 ⁸⁴³ ; Locatelli et al. 2015b ⁸⁴⁴ ). Effective climate policy integration in the land sector is expected to gain from (i) internal policy coherence between adaptation and mitigation objectives, (ii) external climate coherence between climate change and development objectives, (iii) policy integration that favours vertical governance structures to foster effective mainstreaming of climate change into sectoral policies, and (iv) horizontal policy integration through overarching governance structures to enable cross-sectoral coordination (Sections 1.4 and 7.4).

1.4 Enabling the response

Climate change and sustainable development are challenges to society that require action at local, national, transboundary and global scales. Different time-perspectives are also important in decision-making, ranging from immediate actions to long-term planning and investment. Acknowledging the systemic link between food production and consumption, and land-resources more broadly is expected to enhance the success of actions (Bazilian et al. 2011 ⁸⁴⁵ ; Hussey and Pittock 2012 ⁸⁴⁶ ). Because of the complexity of challenges and the diversity of actors involved in addressing these challenges, decision-making would benefit from a portfolio of policy instruments. Decision-making would also be facilitated by overcoming barriers such as inadequate education and funding mechanisms, as well as integrating international decisions into all relevant (sub)national sectoral policies (Section 7.4).

‘Nexus thinking’ emerged as an alternative to the sector-specific governance of natural resource use to achieve global securities of water (D’Odorico et al. 2018 ⁸⁴⁷ ), food and energy (Hoff 2011 ⁸⁴⁸ ; Allan et al. 2015 ⁸⁴⁹ ), and also to address biodiversity concerns (Fischer et al. 2017 ⁸⁵⁰ ). Yet, there is no agreed definition of “nexus” nor a uniform framework to approach the concept, which may be land-focused (Howells et al. 2013 ⁸⁵¹ ), water-focused (Hoff 2011 ⁸⁵² ) or food-centred (Ringler and Lawford 2013 ⁸⁵³ ; Biggs et al. 2015 ⁸⁵⁴ ). Significant barriers remain to establish nexus approaches as part of a wider repertoire of responses to global environmental change, including challenges to cross-disciplinary collaboration, complexity, political economy and the incompatibility of current institutional structures (Hayley et al. 2015 ⁸⁵⁵ ; Wichelns 2017 ⁸⁵⁶ ) (Sections 7.5.6 and 7.6.2).

1.4.1 Governance to enable the response

Governance includes the processes, structures, rules and traditions applied by formal and informal actors including governments, markets, organisations, and their interactions with people. Land governance actors include those affecting policies and markets, and those directly changing land use (Hersperger et al. 2010 ⁸⁵⁸ ). The former includes governments and administrative entities, large companies investing in land, non-governmental institutions and international institutions. It also includes UN agencies that are working at the interface between climate change and land management, such as the FAO and the World Food Programme that have inter alia worked on advancing knowledge to support food security through the improvement of techniques and strategies for more resilient farm systems. Farmers and foresters directly act on land (actors in proximate causes) (Hersperger et al. 2010) (Chapter 7).

Policy design and formulation has often been strongly sectoral. For example, agricultural policy might be concerned with food security, but have little concern for environmental protection or human health. As food, energy and water security and the conservation of biodiversity rank highly on the Agenda 2030 for Sustainable Development, the promotion of synergies between and across sectoral policies is important (IPBES 2018a ⁸⁵⁹ ). This can also reduce the risks of anthropogenic climate forcing through mitigation, and bring greater collaboration between scientists, policymakers, the private sector and land managers in adapting to climate change (FAO 2015a ⁸⁶⁰ ). Polycentric governance (Section 7.6) has emerged as an appropriate way of handling resource management problems, in which the decision-making centres take account of one another in competitive and cooperative relationships and have recourse to conflict resolution mechanisms (Carlisle and Gruby 2017 ⁸⁶¹ ). Polycentric governance is also multi-scale and allows the interaction between actors at different levels (local, regional, national and global) in managing common pool resources such as forests or aquifers.

Implementation of systemic, nexus approaches has been achieved through socio-ecological systems (SES) frameworks that emerged from studies of how institutions affect human incentives, actions and outcomes (Ostrom and Cox 2010 ⁸⁶² ). Recognition of the importance of SES laid the basis for alternative formulations to tackle the sustainable management of land resources focusing specifically on institutional and governance outcomes (Lebel et al. 2006 ⁸⁶³ ; Bodin 2017 ⁸⁶⁴ ). The SES approach also addresses the multiple scales in which the social and ecological dimensions interact (Veldkamp et al. 2011 ⁸⁶⁵ ; Myers et al. 2016 ⁸⁶⁶ ; Azizi et al. 2017 ⁸⁶⁷ ) (Section 6.1).

Adaptation or resilience pathways within the SES frameworks require several attributes, including indigenous and local knowledge (ILK) and trust building for deliberative decision-making and effective collective action, polycentric and multi-layered institutions and responsible authorities that pursue just distributions of benefits to enhance the adaptive capacity of vulnerable groups and communities (Lebel et al. 2006 ⁸⁶⁸ ). The nature, source and mode of knowledge generation are critical to ensure that sustainable solutions are community-owned and fully integrated within the local context (Mistry and Berardi 2016 ⁸⁶⁹ ; Schneider and Buser 2018 ⁸⁷⁰ ). Integrating ILK with scientific information is a prerequisite for such community-owned solutions (Cross-Chapter Box 13 in Chapter 7). ILK is context-specific, transmitted orally or through imitation and demonstration, adaptive to changing environments, and collectivised through a shared social memory (Mistry and Berardi 2016 ⁸⁷¹ ). ILK is also holistic since indigenous people do not seek solutions aimed at adapting to climate change alone, but instead look for solutions to increase their resilience to a wide range of shocks and stresses (Mistry and Berardi 2016 ⁸⁷² ). ILK can be deployed in the practice of climate governance, especially at the local level where actions are informed by the principles of decentralisation and autonomy (Chanza and de Wit 2016 ⁸⁷³ ). ILK need not be viewed as needing confirmation or disapproval by formal science, but rather it can complement scientific knowledge (Klein et al. 2014 ⁸⁷⁴ ).

The capacity to apply individual policy instruments and policy mixes is influenced by governance modes. These modes include hierarchical governance that is centralised and imposes policy through top-down measures, decentralised governance in which public policy is devolved to regional or local government, public-private partnerships that aim for mutual benefits for the public and private sectors and self or private governance that involves decisions beyond the realms of the public sector (IPBES 2018a ⁸⁷⁵ ). These governance modes provide both constraints and opportunities for key actors that impact the effectiveness, efficiency and equity of policy implementation.

1.4.2 Gender agency as a critical factor in climate and land sustainability outcomes

Environmental resource management is not gender neutral. Gender is an essential variable in shaping ecological processes and change, building better prospects for livelihoods and sustainable development (Resurrección 2013 ⁸⁷⁶ ) (Cross-Chapter Box 11 in Chapter 7). Entrenched legal and social structures and power relations constitute additional stressors that render women’s experience of natural resources disproportionately negative when compared to men. Socio-economic drivers and entrenched gender inequalities affect land-based management (Agarwal 2010 ⁸⁷⁷ ). The intersections between climate change, gender and climate adaptation takes place at multiple scales: household, national and international, and adaptive capacities are shaped through power and knowledge.

Germaine to the gender inequities is the unequal access to land-based resources. Women play a significant role in agriculture (Boserup 1989 ⁸⁷⁸ ; Darity 1980 ⁸⁷⁹ ) and rural economies globally (FAO 2011 ⁸⁸⁰ ), but are well below their share of labour in agriculture globally (FAO 2011). In 59% of 161 surveyed countries, customary, traditional and religious practices hinder women’s land rights (OECD 2014 ⁸⁸¹ ). Moreover, women typically shoulder disproportionate responsibility for unpaid domestic work including care-giving activities (Beuchelt and Badstue 2013 ⁸⁸² ) and the provision of water and firewood (UNEP 2016 ⁸⁸³ ). Exposure to violence restricts, in large regions, their mobility for capacity-building activities and productive work outside the home (Day et al. 2005 ⁸⁸⁴ ; UNEP 2016 ⁸⁸⁵ ). Large-scale development projects can erode rights, and lead to over-exploitation of natural resources. Hence, there are cases where reforms related to land-based management, instead of enhancing food security, have tended to increase the vulnerability of both women and men and reduce their ability to adapt to climate change (Pham et al. 2016 ⁸⁸⁶ ). Access to, and control over, land and land-based resources is essential in taking concrete action on land-based mitigation, and inadequate access can affect women’s rights and participation in land governance and management of productive assets.

Timely information, such as from early warning systems, is critical in managing risks, disasters, and land degradation, and in enabling land-based adaptation. Gender, household resources and social status, are all determinants that influence the adoption of land-based strategies (Theriault et al. 2017 ⁸⁸⁷ ). Climate change is not a lone driver in the marginalisation of women; their ability to respond swiftly to its impacts will depend on other socio-economic drivers that may help or hinder action towards adaptive governance. Empowering women and removing gender-based inequities constitutes a mechanism for greater participation in the adoption of sustainable practices of land management (Mello and Schmink 2017 ⁸⁸⁸ ). Improving women’s access to land (Arora-Jonsson 2014 ⁸⁸⁹ ) and other resources (water) and means of economic livelihoods (such as credit and finance) are the prerequisites to enable women to participate in governance and decision-making structures (Namubiru-Mwaura 2014 ⁸⁹⁰ ). Still, women are not a homogenous group, and distinctions through elements of ethnicity, class, age and social status, require a more nuanced approach and not a uniform treatment through vulnerability lenses only. An intersectional approach that accounts for various social identifiers under different situations of power (Rao 2017 ⁸⁹¹ ) is considered suitable to integrate gender into climate change research and helps to recognise overlapping and interdependent systems of power (Djoudi et al. 2016 ⁸⁹² ; Kaijser and Kronsell 2014 ⁸⁹³ ; Moosa and Tuana 2014 ⁸⁹⁴ ; Thompson-Hall et al. 2016 ⁸⁹⁵ ).

1.4.3 Policy instruments

Policy instruments enable governance actors to respond to environmental and societal challenges through policy action. Examples of the range of policy instruments available to public policymakers are discussed below based on four categories of instruments: (i) legal and regulatory instruments, (ii) rights-based instruments and customary norms, (iii) economic and financial instruments, and (iv) social and cultural instruments.

1.4.3.1 Legal and regulatory instruments

Legal and regulatory instruments deal with all aspects of intervention by public policy organisations to correct market failures, expand market reach, or intervene in socially relevant areas with inexistent markets. Such instruments can include legislation to limit the impacts of intensive land management, for example, protecting areas that are susceptible to nitrate pollution or soil erosion. Such instruments can also set standards or threshold values, for example, mandated water quality limits, organic production standards, or geographically defined regional food products. Legal and regulatory instruments may also define liability rules, for example, where environmental standards are not met, as well as establishing long-term agreements for land resource protection with land owners and land users.

1.4.3.2 Economic and financial instruments

Economic (such as taxes, subsidies) and financial (weather-index insurance) instruments deal with the many ways in which public policy organisations can intervene in markets. A number of instruments are available to support climate mitigation actions including public provision, environmental regulations, creating property rights and markets (Sterner 2003 ⁸⁹⁶ ). Market-based policies such as carbon taxes, fuel taxes, cap and trade systems or green payments have been promoted (mostly in industrial economies) to encourage markets and businesses to contribute to climate mitigation, but their effectiveness to date has not always matched expectations (Grolleau et al. 2016 ⁸⁹⁷ ) (Section 7.4.4). Market-based instruments in ecosystem services generate both positive (incentives for conservation), but also negative environmental impacts, and also push food prices up or increase price instability (Gómez-Baggethun and Muradian 2015 ⁸⁹⁸ ; Farley and Voinov 2016 ⁸⁹⁹ ). Footprint labels can be an effective means of shifting consumer behaviour. However, private labels focusing on a single metric (e.g., carbon) may give misleading signals if they target a portion of the life cycle (e.g., transport) (Appleton 2009 ⁹⁰⁰ ) or ignore other ecological indicators (water, nutrients, biodiversity) (van Noordwijk and Brussaard 2014 ⁹⁰¹ ).

Effective and durable, market-led responses for climate mitigation depend on business models that internalise the cost of emissions into economic calculations. Such ‘business transformation’ would itself require integrated policies and strategies that aim to account for emissions in economic activities (Biagini and Miller 2013 ⁹⁰² ; Weitzman 2014 ⁹⁰³ ; Eidelwein et al. 2018 ⁹⁰⁴ ). International initiatives such as REDD+ and agricultural commodity roundtables (beef, soybeans, palm oil, sugar) are expanding the scope of private sector participation in climate mitigation (Nepstad et al. 2013 ⁹⁰⁵ ), but their impacts have not always been effective (Denis et al. 2014 ⁹⁰⁶ ). Payments for environmental services (PES) defined as “voluntary transactions between service users and service providers that are conditional on agreed rules of natural resource management for generating offsite services” (Wunder 2015 ⁹⁰⁷ ) have not been widely adopted and have not yet been demonstrated to deliver as effectively as originally hoped (Börner et al. 2017 ⁹⁰⁸ ) (Sections 7.4 and 7.5). PES in forestry were shown to be effective only when coupled with appropriate regulatory measures (Alix-Garcia and Wolff 2014 ⁹⁰⁹ ). Better designed and expanded PES schemes would encourage integrated soil–water–nutrient management packages (Stavi et al. 2016 ⁹¹⁰ ), services for pollinator protection (Nicole 2015 ⁹¹¹ ), water use governance under scarcity, and engage both public and private actors (Loch et al. 2013 ⁹¹² ). Effective PES also requires better economic metrics to account for human- directed losses in terrestrial ecosystems and to food potential, and to address market failures or externalities unaccounted for in market valuation of ecosystem services.

Resilient strategies for climate adaptation can rely on the construction of markets through social networks as in the case of livestock systems (Denis et al. 2014 ⁹¹³ ) or when market signals encourage adaptation through land markets or supply chain incentives for sustainable land management practices (Anderson et al. 2018 ⁹¹⁴ ). Adequate policy (through regulations, investments in research and development or support to social capabilities) can support private initiatives for effective solutions to restore degraded lands (Reed and Stringer 2015 ⁹¹⁵ ), or mitigate against risk and to avoid shifting risks to the public (Biagini and Miller 2013 ⁹¹⁶ ). Governments, private business, and community groups could also partner to develop sustainable production codes (Chartres and Noble 2015 ⁹¹⁷ ), and in co-managing land-based resources (Baker and Chapin 2018 ⁹¹⁸ ), while public-private partnerships can be effective mechanisms in deploying infrastructure to cope with climatic events (floods) and for climate-indexed insurance (Kunreuther 2015 ⁹¹⁹ ). Private initiatives that depend on trade for climate adaptation and mitigation require reliable trading systems that do not impede climate mitigation objectives (Elbehri et al. 2015 ⁹²⁰ ; Mathews 2017 ⁹²¹ ).

1.4.3.3 Rights-based instruments and customary norms

Rights-based instruments and customary norms deal with the equitable and fair management of land resources for all people (IPBES 2018a ⁹²² ). These instruments emphasise the rights in particular of indigenous peoples and local communities, including for example, recognition of the rights embedded in the access to, and use of, common land. Common land includes situations without legal ownership (e.g., hunter-gathering communities in South America or Africa, and bushmeat), where the legal ownership is distinct from usage rights (Mediterranean transhumance grazing systems), or mixed ownership-common grazing systems (e.g., crofting in Scotland). A lack of formal (legal) ownership has often led to the loss of access rights to land, where these rights were also not formally enshrined in law, which especially effects indigenous communities, for example, deforestation in the Amazon basin. Overcoming the constraints associated with common-pool resources (forestry, fisheries, water) are often of economic and institutional nature (Hinkel et al. 2014 ⁹²³ ) and require tackling the absence or poor functioning of institutions and the structural constraints that they engender through access and control levers using policies and markets and other mechanisms (Schut et al. 2016 ⁹²⁴ ). Other examples of rights-based instruments include the protection of heritage sites, sacred sites and peace parks (IPBES 2018a ⁹²⁵ ). Rights-based instruments and customary norms are consistent with the aims of international and national human rights, and the critical issue of liability in the climate change problem.

1.4.3.4 Social and cultural norms

Social and cultural instruments are concerned with the communication of knowledge about conscious consumption patterns and resource-effective ways of life through awareness raising, education and communication of the quality and the provenance of land-based products. Examples of the latter include consumption choices aided by ecolabelling (Section 1.4.3.2) and certification. Cultural indicators (such as social capital, cooperation, gender equity, women’s knowledge, socio-ecological mobility) contribute to the resilience of social-ecological systems (Sterling et al. 2017 ⁹²⁶ ). Indigenous communities (such as the Inuit and Tsleil Waututh Nation in Canada) that continue to maintain traditional foods exhibit greater dietary quality and adequacy (Sheehy et al. 2015 ⁹²⁷ ). Social and cultural instruments also include approaches to self-regulation and voluntary agreements, especially with respect to environmental management and land resource use. This is becoming especially irrelevant for the increasingly important domain of corporate social responsibility (Halkos and Skouloudis 2016 ⁹²⁸ ).

1.5 The interdisciplinary nature of the SRCCL

Assessing the land system in view of the multiple challenges that are covered by the SRCCL requires a broad, inter-disciplinary perspective. Methods, core concepts and definitions are used differently in different sectors, geographic regions, and across academic communities addressing land systems, and these concepts and approaches to research are also undergoing a change in their interpretation through time. These differences reflect varying perspectives, in nuances or emphasis, on land as components of the climate and socio-economic systems. Because of its inter-disciplinary nature, the SRCCL can take advantage of these varying perspectives and the diverse methods that accompany them. That way, the report aims to support decision- makers across sectors and world regions in the interpretation of its main findings and support the implementation of solutions.

Footnotes

1. Different communities have a different understanding of the concept of pathways (IPCC 2018). Here, we refer to pathways as a description of the time-dependent actions required to move from today’s world to a set of future visions (IPCC 2018). However, the term pathways is commonly used in the climate change literature as a synonym for projections or trajectories (e.g., shared socio-economic pathways).
2. Uncertainty here is defined as the coefficient of variation CV. In the case of micrometeorological fluxes they refer to random errors and CV of daily average.
