Resumo
Desertification phenomenon is consequence of a set of various processes in arid and semi-arid environments, in which water is the major factor for the use of lands in the ecosystems. It is generally associated to geo-physical conditions (e.g. soil, slope, vegetation cover) coupled with inclemency of drought and also water availability . Several methods have been developed to evaluate desertification process, including mathematical models, parametric equations, remote sensing, direct observation and measurement .
