ANÁLISE DA DINÂMICA DO USO E COBERTURA DO SOLO NO MUNICÍPIO DE ITABUNA, BAHIA

ANALYSIS OF THE DYNAMICS OF LAND USE AND COVER IN THE MUNICIPALITY OF ITABUNA, BAHIA

Abstract

Using data from remote sensing as a basis for studies on mapping land cover and use is a world-renowned practice, as it allows a dynamic and spatial analysis of the different classes existing in the territory. In this context, the main objective of this work was to analyze the dynamics of land cover and use in the municipality of Itabuna-BA, from 1985 to 2021, through data obtained by remote sensing. The data used came from MapBiomas project, and the processing and analysis of this data was carried out with the help of QGIS and Excel software.  The results revealed a significant replacement of Forest Formation class by other categories, such as Pasture, Mosaic of Uses and Urbanized Area. The evolution of urban areas in the municipality was also observed, with a significant increase in the Urbanized Area class from 2003 onwards. Furthermore, there was a growing process of urbanization and irregular occupation of preservation areas along the Cachoeira river. Through the results found, we can see the importance and urgency of implementing public policies aimed at environmental conservation and sustainable development, as alternatives to reduce the negative impacts resulting from disorderly urban growth in the municipality of Itabuna-BA.
