| Abstract: | This article looks at desertification — both on a global scale and as it relates to Africa. Desertification is defined here as the diminution or destruction of the biological potential of the land, and is caused basically by overuse of inherently fragile productive systems. After distinguishing between desertification and drought (two closely related ecological hazards), the author goes on to outline the terrible effects of desertification and the impact it has on the world population's ability to feed itself. Finally, recommendations to halt and reverse desertification are looked at together with attempts to mobilize the resources needed to face this global problem. |
