Abstract

This work aimed to review the aspect of desertification, its concept, causes and its control with special reference to Sudan. It appeared that there was a wide controversy among scientists on the concept of desertification and its causes. In Sudan about 5 x 105km2 are directly affected by desertification, where more than half the population of the Sudan live in this area. Recent increase in human and livestock has led to the improvement of the semi-arid zone of the Sudan and consequently land cultivation has advanced about 200km north of the agronomic dry boundary. High variability of rainfall which is a norm of typical arid zone indices high vulnerability of ecosystems rendered the semi arid zone to more prone to desertification. The land that was irrationally used by man, the excusive utilization of soil had taken form of over cultivation, overgrazing, and deforestation in addition to fires. (1) was investigated, it is prospective and might be appropriate to control desertification and mitigate its effects if it is implemented appropriately. Results reviled that there was a large controversy in the definition of desertification. In Sudan the increase in population might be the main causes of desertification in semi arid region of the country.
