This study examines the dynamics of land use and cover in Chapadinha, Maranhão, Brazil, focusing on the years 1985, 2009, and 2021. The region, part of the Cerrado biome, is undergoing significant changes due to agricultural expansion and climate change, exacerbated by a lack of targeted public policies. The study employs geoprocessing techniques to analyze landscape transformations, using data from the MapBiomas Project and GIS software. The results show a decrease in Forest Formation from 84.5% in 1985 to 83.6% in 2021, with a corresponding increase in agricultural and urbanized areas. Soy cultivation, in particular, has expanded significantly, from virtually non-existent in 1985 to covering 2.0% of the area in 2021. This expansion is linked to the migration of southern producers and the arrival of large companies in the region. The study highlights the environmental impacts of these changes, including deforestation, biodiversity loss, and soil degradation. It emphasizes the need for sustainable agricultural practices to mitigate these effects and ensure the preservation of natural resources in Chapadinha.
