Desertification, land degradation and drought affect more than 2 billion people and the situation might worsen due to the unsustainable use of soil and water under present scenarios of climate change. The UNCCD 10-year strategy points out the importance of science, knowledge sharing systems and awareness raising to support policymakers in reversing this trend. Sustainable land management practices, including sustainable agriculture, provide important local, regional and global benefits.

The drylands of Africa, exclusive of hyper-arid zones, occupy about 43 per cent of the continent, and are home to a rapidly growing population that currently stands at about 325 million people. Dry zones, inclusive of hyper-arid lands, cover over 70 per cent of the continent’s terrestrial surface. Outside of the cities many dryland inhabitants are either pastoralists, sedentary or nomadic, or agro-pastoralists, combining livestock-rearing and crop production where conditions allow.

Human activities have resulted in unprecedented phenomena and severe impacts for the 21st century such as land degradation, natural resources scarcity, climate change, and a rapid decline in biodiversity. These alterations engender secondary effects such as political conflicts, disputes over resources, social disruptions and sudden shocks of catastrophic weather events which are becoming more frequent in critical regions of the world, particularly in drylands; and exacerbate threats for human, national and international security.
