Dinâmica do uso e cobertura da terra no município de Corrente, Piauí, por meio de técnicas de sensoriamento remoto

Abstract

The study analyzed changes in land use and cover in the municipality of Corrente, Piauí, between 1985 and 2023, using satellite images and geoprocessing techniques. The main objective was to map and quantify changes in the landscape, with a focus on agricultural expansion and its environmental impacts. The results revealed a significant increase in pasture and crop areas, with a consequent reduction in native Cerrado vegetation. Agricultural expansion, driven by the cultivation of soy, corn and cotton, was the main driver of these changes, leading to habitat fragmentation, loss of biodiversity and alteration of the water regime. The study highlights the importance of continuous monitoring of land use and the implementation of public policies to promote sustainable development in the MATOPIBA region. The use of remote sensing and geoprocessing techniques proved effective in analyzing the dynamics of land use and land cover in Corrente, Piauí. The research contributes to territorial planning and environmental management, providing crucial information for decision-making on the use of natural resources and the conservation of biodiversity
