             abstract = "Desertification is a generalized process of degradation that 
                         impedes economic growth and social development, consequent of 
                         deterioration of soils, water resources, vegetation, biodiversity 
                         loss, allowing a decrease in the potential of environmental 
                         resources. Over 60% of the state of Bahia is inserted in semi-arid 
                         climate, characterized by a set of physical variables, biological 
                         and social, which can trigger the desertification process. So 
                         becomes relevance the recognition of relevant forms of use and 
                         coverage of these spaces for the formulation of key indicators 
                         which contribute to the expansion of this process. In this 
                         perspective, this work has identified, mapped and analyzed the use 
                         and coverage of land in the northern state, identified as area 
                         susceptible to desertification. For this, the methodology is based 
                         on digital image processing of Landsat and Modis, associated with 
                         the interpretation of NDVI; pre-existing data and surveys of 
                         primary data in the field. The results show that the soils and 
                         vegetation are the most common resources and represent the basis 
                         of sustainability of most activities performed by the local 
                         population, which has led to their increasing exposure to erosive 
                         agents. The nature of these processes relates to agriculture 
                         associated with traditional management practices such as slash and 
                         / or indiscriminate burning of vegetation for pasture and crops, 
                         extensive breeding of goats, sheep and cattle, which generate 
                         overgrazing and soil compaction, capable of provide differential 
                         erosion that undermines the permanence of rural activities, as 
                         well as accentuate the rusticity of the vegetation.",
