LAND USE AND OCCUPATION IN THE SEMIARID REGION OF BAHIA: A CASE STUDY IN THE MUNICIPALITY OF ANTÔNIO GONÇALVES - BA

Abstract

The mapping technique is one of the most appropriate ways of representing the geographic space, and it has become an important ally in the construction of environmental scenarios (JHON, 2009; WANG et al., 2010). In view of these findings, this work aims to propose a mapping of land use and occupation in the municipality of Antônio Gonçalves (BA), as a subsidy for environmental planning. To this end, the work was divided into three main stages: the first consisted of a bibliographic review; the second, consisting of the acquisition of Landsat-TM images and the third stage characterized by the integration of the data collected in a GIS environment, using the QGIS software (version 3.10.14) and the final writing of the research. Regarding the results, the predominance of shrubby caatinga was observed, whose existence is explained by the climatic context. There was also a large presence of forest areas, while the classes of herbaceous vegetation, exposed soils, urban areas, agricultural crops and continental water were a minority in the spectral result of use and occupation. In general, it is expected that this work can be the starting point for other studies that propose to better diagnose the dynamics of land use and occupation in the municipality of Antônio Gonçalves - BA.
