surrounding areas, as Schulz et al (2003) point out the process is actually rather more complex than this. As they note, in the Sudan desertification is the result of both
socio-economic and ecological factors. As Hassan (2003) states, Sudan has suffered from a drought cycle since the late 60s and is now coping with the consequences of this cycle, including
desert encroachment. Rainfall varies from 1300mm in the Savannah to 0mm in the northern desert regions. Desert and semi-desert areas make up over half of the countrys total land mass,
and if the low-rainfall areas of the Savannah are included, this brings the figure up to over 80%.
The ecological effects of desertification are diverse and widespread. There are, for instance, five types of soil degradation which
can be identified in the Sudan: wind and water erosion, and depletion of fertility, salinity and alkalinity in soils. Wind erosion is particularly prevalent in areas where desert advance encroaches
on grazing land, and as a result of overgrazing, fires and tree-felling, areas around inhabited regions have changed to shifting sands in recent years. Desert sand is encroaching at a
rapid rate, and wind erosion also causes soil damage in the flood plains of the Nile. Water erosion also causes soil degradation, particularly in areas where there is a combination
of heavy rainfall and the destruction of vegetation through fires.
Hassan also notes that in some regions where mono-culture cultivation is practised, this is carried without consideration for the potentially damaging impact on the soil: the clearance
