Desertification has its greatest impact in Africa. Two thirds of the continent is desert or drylands. There are extensive agricultural drylands, almost three quarters of which are already degraded to some degree. The region is afflicted by frequent and severe droughts. Many African countries are landlocked, have widespread poverty, need external assistance, and depend heavily on natural resources for subsistence. They have difficult socio-economic conditions, insufficient institutional and legal frameworks, incomplete infrastructure, and weak scientific, technical, and educational capacities. These difficult circumstances explain why African countries have put so much effort into convincing the international community of the need for a "Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa".
Africa's desertification is strongly linked to poverty, migration, and food security. In many African countries, combating desertification and promoting development are virtually one and the same due to the social and economic importance of natural resources and agriculture. When people live in poverty, they have little choice but to over-exploit the land. When the land eventually becomes uneconomic to farm, these people are often forced into internal and cross-border migrations, which in turn can further strain the environment and cause social and political tensions and conflicts. (The link with migration was important to the international community's recognition of desertification as a truly global problem, like climate change or biodiversity loss.) Food security can ultimately be put at risk when people already living on the edge face severe droughts and other calamities.
Desertification is defined as soil degradation in arid regions, often to such an extent that it is impossible to make the soil productive again. It is the result of complex interactions between unp...
