Desertification. This is the process that sees productive land turned into non-productive desert. It usually affects dry areas on the edge of deserts, eg The Sahel, south of the Sahara Desert in Africa. What causes desertification? Desertification is a complex process. It is caused by physical processes and human mismanagement. Factors which may cause desertification include: Climate change â especially long dry periods, causing drought. The dry conditions cause the vegetation to die, so the land loses the protective cover that vegetation provides. Too many animals within the area â leads to overgrazing. Population growth â traditional, less intensive, methods of farming decline.
