Identification of areas susceptible to desertification in the Alagoas dairy basin

Authors

Abstract

Located in the Brazilian Northeast, the semi-arid region of Alagoas has shown strong and diverse signs of susceptibility to desertification. In this way, through remote sensing and field visits, the objective was to identify desertified territories or those with a high level of susceptibility to degradation in the semiarid region of Alagoas. Thus, satellite data referring to the period from 2013 to 2022 were used to identify and monitor desertified or potential regions, being processed in Qgis. In addition, photographs and notes were taken through on-site visits to the study area. The significant degradation of the study area and the intense anthropization of areas classified as natural in MapBiomas were evidenced through field visits, indicating the region's high vulnerability to the desertification process. Livestock is predominant in the territory analyzed, followed by the forest, which, even so, had its area reduced due to the rise of agriculture and livestock. Remote sensing provides valuable information about the space-time dynamics of a given region, however, ensuring data integrity through in loco monitoring is essential, given the limitations to which geoprocessing tools are subject.
