Located in the arid and semi-arid areas of West Africa, the Sahel has undergone profound changes over the past 50 years. Known for the prevalence of land degradation processes, the Sahel is suffering from the combined negative effects of population growth, human activities and climate variability, resulting in recurrent droughts and the continued decline of natural resources and land productivity.

The UNCCD-SPI technical report “Realising the Carbon Benefits of Sustainable Land Management Practices: Guidelines for Estimation of Soil Organic Carbon in the Context of Land Degradation” provides decision guidance for the estimation of soil organic carbon (SOC) in support of appropriate deployment of sustainable land management (SLM) technologies, in order to maintain or increase carbon in the soil and contribute to the achievement of land degradation neutrality (LDN).

Two billion hectares of productive land are degraded worldwide. This is an area larger than South America or twice the size of China, and 500 million hectares of this is abandoned agricultural land. We continue to degrade another 12 million hectares of productive land every year. We need to break this destructive cycle because the benefits of preventing land degradation and reversing it are far greater than the gains from degrading new land year after year.

Numbers can tell a compelling story. In this brochure, the numbers highlight how much we rely on productive land. Amongst other valuable services, land feeds our families, provides fresh water and powers our future ambitions. Much of the data collected here, however, demonstrate how close we are to pushing our relationship with the land to breaking point. The magnitude of the challenges and potential consequences of failing to implement bold action on land and soil, in terms of future social stability and economic development, should not be underestimated.

The Global Environment Facility (GEF)/United Nations Environment Programme (UNEP)/United Nations University (UNU) PALM project is an initiative of the governments of Tajikistan and Kyrgyzstan which aims to restore, sustain and enhance the productive and protective functions of the transboundary ecosystems of the High Pamir and Pamir-Alai mountains, so as to improve the social and economic well-being of the rural communities and households utilizing the region's ecosystem resources to meet their livelihood needs, while preserving its unique landscape and globally important biodiversity.

Land degradation exacerbates the unique vulnerabilities of Small Island Developing States (SIDS) to environmental challenges, such as climate change, flash floods, soil erosion, lagoon siltation, coastal erosion and sea level rise, undermining their economic potential. Land Degradation Neutrality (LDN) contributes to achieving the Sustainable Development Goals (SDGs) in SIDS, preserving biodiversity and increasing resilience to climate change. Land degradation has a strong negative impact on climate-sensitive sectors like agriculture, water resources management and coastal zone management.

Drylands are complex social-ecological systems, characterized by non-linearity of causation, complex feedback loops within and between the many different social, ecological, and economic entities, and potential of regime shifts to alternative stable states as a result of thresholds. As such, dryland management faces a high level of uncertainty and unpredictability.

The GEF Land Degradation Focal Area provides the framework for eligible countries1 to utilize GEF resources for implementing the UNCCD. Through the focal area, the GEF provides incremental financing for countries to invest in sustainable land management (SLM) activities that generate multiple environmental and development benefits. In most developing countries, SLM represents a major opportunity for sustainable intensification of existing farmlands, leading to sustained productivity.

Productive land is a critical natural asset for rural communities in developing nations, providing them with a wide range of ecosystem resources, such as water, fertile soils, plant and genetic diversity – on which they depend daily for survival. For many communities, the land is also an integral part of their cultural identity, helping to maintain social cohesion and stability, in addition to building resilience to socio-ecological shocks and risks such as those caused by climate change. But land is a vulnerable resource that must be managed and restored to ensure a sustainable future.

Small Island Developing States (SIDS) are continuously under the threat from the adverse effects of climate change and land degradation impacts. Erratic climatic patterns have made daily weather previsions unreliable and are becoming a challenge for communities to take appropriate timely and preventive measures. Land degradation directly increases CO2 emissions, contributing to climate change and vice versa.

This Toolkit has been prepared to support the design and implementation of Sustainable Land Management (SLM) programs. The specific purpose of the Toolkit is: to inform the user of the approaches that can be followed to analyze and value the economic costs of land degradation and the benefits of sustainable land management. ‘Land’ is interpreted broadly in the Toolkit, also including wetlands and coastal zones. The Toolkit contains five Tools that together present a detailed description of the various relevant ecological and economic assessment methodologies.

Land has a value for each and every one of us. Fertile soil provides us with plant life, vegetables, grains, and fibres. Forests supply us with timber and firewood. We benefit from fresh water, food, and many other ecosystem services that land provides us with. Land is also emotionally valuable to people as well, perhaps through associating treasured memories such as playing on it as a child. In any case, all societies and people assign historical and cultural value to their landscapes, their nature, and all natural phenomena associated with land. However, lands are in danger.
