    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 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).

    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 2019 edition of the Land for Life Award puts the spotlight on individuals and organizations that made outstanding contributions to achieve land degradation neutrality on a large scale, with long-term changes and dedicated actions for 25 years or longer. Those remarkable projects involve local people, communities and the society, raising the level of their ambition. Meanwhile, recent assessments remind us that two billion hectares of land are now degraded worldwide. This represents an area larger than the territory of the Russian Federation, the biggest country in the world.

    Land degradation and biodiversity loss are among the most pressing environmental challenges facing humanity. Land degradation has reduced the productivity of nearly one-quarter of the global land surface, impacted the wellbeing of about 3.2 billion people and cost about 10% of annual global gross domestic product in lost ecosystem services. An estimated 23% of total anthropogenic greenhouse gas emissions derive from agriculture, forestry and other land uses, contributing to climate change.

    Deforestation, land degradation, and unsustainable land management threaten our lives and are responsible, both directly and indirectly, for many economic, social and environmental issues. In particular, countries in Northeast Asia face the growing threats of desertification, land degradation and drought (DLDD). In China, it is estimated that “more than 40 per cent of Chinese arable land is degraded” (China Daily 2014). “The annual cost of land degradation in Mongolia is estimated at 2.1 billion United States dollars (USD)” (UNCCD, 2018).

    The extensive arable land and great biodiversity present in Latin America and the Caribbean (LAC) have the potential to ensure sustenance and a good quality of life for its more than 600 million inhabitants. LAC has experienced important changes in land use. When the Europeans arrived in the 15th century, the forest cover of LAC accounted for approximately 75 per cent of the territory.

    Land Degradation Neutrality is a new way of approaching land degradation that acknowledges that land and land-based ecosystems are affected by global environmental change as well as by local land use practices. Achieving the target of a land degradation neutral world encourages adaptive management during planning, implementation, and monitoring of LDN-related activities and follows the LDN response hierarchy of avoiding, reducing, and reversing land degradation.

    Women constitute the bulk of people who rely on land in many of the regions most affected by desertification, land degradation and drought. One in three people on earth depend directly on agriculture, while nearly 80% of employed women in least developed countries report agriculture as their primary livelihood. Food availability fluctuations also impact women’s role in food production and intra-family food distribution, with women often reducing their nutritional intake and that of their children, with dire health consequences.

    This UNCCD-SPI technical report provides well-established scientific evidence for understanding the strong linkages between land use and drought and how management of both is connected through water use. It introduces a new concept of Drought-smart land management (D-SLM) and organizes relevant approaches and practices in fourteen groups across four major classes of land use.
