"Desertification is land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors including climatic variations and human activities".

A more graphic and descriptive definition of the process is given by Le Houerou [1995]: "The nature of the phenomenon is essentially the exposure of the soil/land surface increasingly stripped of its perennial vegetation and thus submitted, without any protection, to the forces of water and wind erosion. In low rainfall areas, on shallow soils, the phenomenon may be irreversible. That is to say, a piece of land thus degraded cannot return to pristine condition, under total protection from disturbance, over a period of 25 years. This is what has been called 'Desertization', which differs from land degradation by its irreversible nature." Other definitions include:

"Desertification, revealed by drought, is caused by human activities in which the carrying capacities of land is exceeded; it proceeds by exacerbated natural or man induced mechanims, and is made manifest by intricate steps of vegetation and soil deterioration which result, in human terms, in an irreversible decrease or destruction of the biological potential of the land and its ability to support population."
