TEMPORAL ANALYSIS OF LAND USE AND OCCUPATION IN THE MUNICIPALITY OF ITABERABA, BAHIA, BRAZIL

The present work proposes, in face of the significant alterations of land use and occupation in the Brazilian semiarid region, to analyze the spatial modifications of the main types of land use and occupation in the municipality of Itaberaba, on a temporal scale of 40 years, considering the dates 1980, 2000 and 2020, in order to contribute to the decision making process regarding the planning and land use planning. To this end, a bibliographic review of the works that addresses land use and occupation in the municipality in question was elaborated, with a brief synthesis of the historical, economic and social formation, as well as the acquisition and processing of Landsat-TM satellite images in the three historical periods with records of the use and occupation classes developed through the use of GIS. In this sense, in the historical-spatial course of 40 years, it was verified that there was a considerable increase in the areas of agricultural crops and pastures (with an increase of approximately 400% of the area covered in the municipality), exposed soil, and urbanized areas to the detriment of the areas corresponding to the native vegetation of the local caatinga biome (which decreased more than 68% of the coverage in the analyzed period). Such significant changes can be justified as a consequence of the expansion of pineapple cultivation (Ananas comosus) and the implementation of industries in the municipal territory from the 2000s.
