    Desertification could be seen as a process whereby the productivity of arid or semi-arid land falls by 10% or more (Miller, 1999). Miller (1999) classified desertification as mild, serious and severe based on soil productivity. Mild desertification is a 10 to 25% drop in productivity, serious Desertification. Desertification is defined by the United Nations (1980) as “diminution or destruction of the biological potential of the land which can lead ultimately to desert-like conditions.
