    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.

    Human activities are the principal drivers of the processes of land degradation, desertification and climate change. Though highly complex and difficult to predict, interactions between climate change and land degradation are likely to affect a range of different ecosystem functions and the services they deliver, with consequent impacts on food production, livelihoods and human well-being. Society must therefore mitigate or reverse these stresses through innovative approaches.

    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.

    Energy is central to nearly every major challenge and opportunity the world faces today. Be it for jobs, security, climate change, food production or increasing incomes, access to energy for all is essential. Sustainable energy is an opportunity too as it fuels lives, economies and the planet. Getting sustainable energy to all who want it represents one of the biggest development challenges of the 21st century.

    Land is an essential building block of civilization yet its contribution to our quality of life is perceived and valued in starkly different and often incompatible ways. Conflicts about land use are intensifying in many countries. The world has reached a point where we must reconcile these differences and rethink the way in which we use and manage the land.

    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.

    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.

    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).

    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.

    In the last decade, there have been a number of global/regional targets and initiatives to halt and reverse land degradation and restore degraded land. Starting in 2010, these include the CBD’s Aichi Biodiversity Targets, one of which aims to restore at least 15% of degraded ecosystems; the Bonn Challenge and its regional initiatives to restore more than 150 million hectares; and most recently the 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs).
