Desertification in the Sudan: causes,effects and policy options

Desertification is the spread of desert-like conditions in arid and semi-arid conditions. It is a result of pressure from both climatic and human factors. Desertification in the Sudan has been accelerating at a faster rate over the last two decades, leading to marginalization and the loss of arable land. The main factors contributing to desertification include drought, population growth, the spread of extensive agriculture, deforestation, rapid urbanization, the erosion of local political power, the lack of economic institutions and the absence of social institutions which have tended to reduce the capacity of the local people to cope with the resource degradation problem. Initiatives to arrest the desert encroachment must include improved cultivation methods, proper grazing management, reforestation and integration of livestock and crop production systems, coupled with good linkages to light processing industries.

This paper identifies the causal factors of desert encroachment, assesses its impact on the environment and humanity and concludes by recommending specific strategies to control the desert encroachment problem.
