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.

The Economics of Desertification, Land Degradation and Drought
Rapports et recherchesfévrier, 2011GlobalThe economic dimension of desertification, land degradation and drought (DLDD) is increasingly gaining importance.
For this reason, the UNCCD has launched an initiative to help make the economic side of desertification, land degradation and drought (DLDD) an integral part of policy strategies and decision-making. An important step in this direction was the Partnership meeting on the Assessment of the »Economics of Desertification, Land Degradation and Drought« ( EDLDD), held December 14 – 15, 2010.

More than two billion people depend on the world’s arid and semi-arid lands. Preventing land degradation and supporting sustainable development in drylands has major implications for food security, climate change and human settlement. This report, issued at the beginning of the United Nations Decade for Deserts and the Fight against Desertification, sets out a shared strategy by UN agencies to rise to the challenge of addressing the special needs of these vital zones.

The rate and quality of production generated from the land depends on its major components, soil and its fertility. Soil organic matter, derived from the vegetation supported by a particular soil, is the major component that controls soil fertility.

Les terres3 peutvent se définir comme un système destiné à générer de la productivité biologique. C’est l’infrastructure naturelle qui supporte la vie sur la planète. La quantité et la qualité de cette production dépendent du principal composant de la terre : le sol et sa fertilité. La matière organique du sol, qui provient de la végétation portée par ce dernier, est le principal composant influençant la fertilité du sol.
