Descripción:	The Chapadinha microregion stands out in soybean cultivation, accounting for 78% of production in eastern Maranhão. The replacement of natural vegetation with soybean farming has impacted biodiversity, regional water cycles, and ecological balance. Therefore, the aim this study was to comprehend the land use and land cover using geoprocessing techniques and multivariate analysis, in a soybean cultivation region situated at the Maranhão state, Brazil. The methodology integrated the use of two approaches for spatiotemporal analysis. The first approach utilizes a database from the Annual Land Use and Land Cover Mapping Project in Brazil (MAPBIOMAS) applied to Chapadinha, Anapurus, and Mata Roma on the 1985, 2009, and 2021 years. The second consisted in multivariate analysis for to understand the dynamics of land use classes. The results revealed that the area dedicated to soybean cultivation significantly increased, reaching 6,442 hectares in Chapadinha, 8,200 hectares in Mata Roma, and 10,825 hectares in Anapurus on the 2021. The multivariate analysis highlighted a substantial increase in soybean-cultivated lands in Anapurus and Mata Roma on the 2009 and 2021 years. It contrasted for the forest and savanna vegetations reductions. This study provides insight into the advancement of soybean cultivation in the Chapadinha microregion, highlighting the need for greater oversight and policies aimed at the sustainable use of natural resources, especially in the face of growing global food demand and the development of emerging economies.
