                         as semi-arid land and has been undergoing intense land use 
                         processes in the last decades, which have resulted in severe 
                         degradation of its natural assets. Therefore, the objective of 
                         this study is to identify the areas that are susceptible to 
                         desertification in this region based on the 11 influencing factors 
                         of desertification (pedology, geology, geomorphology, topography 
                         data, land use and land cover change, aridity index, livestock 
                         density, rural population density, fire hot spot density, human 
                         development index, conservation units) which were simulated for 
                         two different periods: 2000 and 2010. Each indicator were assigned 
                         weights ranging from 1 to 2 (representing the best and the worst 
                         conditions), representing classes indicating low, moderate and 
                         high susceptibility to desertification. The results indicate that 
                         94 % of the Brazilian northeast region is under moderate to high 
                         susceptibility to desertification. The areas that were susceptible 
                         to soil desertification increased by approximately 4.6 % (83.4 
                         km2) from 2000 to 2010. The implementation of the methodology 
                         provides the technical basis for decisionmaking that involves 
                         mitigating actions and the first comprehensive national assessment
