Desertification is the degradation of the scenarios that impact the environmental system. It is originated through natural dynamics and anthropogenic actions, as nature is exploited by extreme economic rationalities under a squandering logic, which intensifies the environmental crisis. The vulnerable areas to desertification are those with greater climate fragility (irregular rainfall distribution, occurrence of heavy precipitation and / or very dry periods); shallow soils prone to erosion, changes in spatial organization and economic production (economic weakening and emigrations). In this sense, this research tries to understand the processes of vulnerability to desertification in Alto Sertao of Sergipe, based on relevant bibliography and field-work data collected in the area of study. In Alto Sertao Sergipe desertification is dynamic and develops over a fragile eco-geosystem, It´s vulnerability is analyzed through a geographic focus.
