             abstract = "Desertification is defined for UNEP (1991), as the degradation of 
                         lands in arid, semi-arid and sub-humid dry areas. In brazilian 
                         semi-arid region has demonstrated the pressure of human occupation 
                         changes, which are developed in non-sustainable form. This 
                         phenomenon is a climatic threat for biodiversity and its 
                         associated with climatic change and the lost of soil productivity 
                         and mainly for bad landscape use and human occupation. To monitor 
                         these transformation its become indispensable the use of Remote 
                         Sensing and Geographic Information System (GIS). Thus, in this 
                         work suggested a multitemporal analysis to monitoring susceptible 
                         areas for desertification in brazilian semi-arid in Cedro-PE. The 
                         selected area for this study is situated in the central-Southern 
                         Semi-Arid part of the Pernambuco State of Northeastern Brazil, it 
                         covers about 172 km2 and lies between 7§ 48` and 7§ 39` S 
                         latitude; 30§ 18` and 39§ 05` W longitude respectively. 
                         TM/Landsat-5, (bands 3, 4, 5)images were acquired in two extremes 
                         dates (25/09/1986 and 01/08/2001)and analyzed in a Georreferenced 
                         Information Processing System (SPRING), available at INPE`s Image 
                         Threatment Laboratory (LTID). It's permitted estimate, compare and 
                         quantify the occupation areas like water, boreland, agricultural 
                         area, urban area and natural vegetation for supervisioned 
                         classification and subtraction of images. As result was obtained a 
                         thematic map with detection and analysis of the modifications
