Análise temporal do uso e cobertura da terra do município de Manoel Urbano-AC nos anos de 1985, 1996, 2006, 2015 e 2023 através de imagens Landsat

Abstract

This study aims to conduct a temporal analysis of land use and land cover dynamics in the municipality of Manoel Urbano, Acre, Brazil, for the years 1985, 1996, 2006, 2015, and 2023. The methodology involved Remote Sensing and geoprocessing tools, with images processed and classified in QGIS software. The results revealed a high level of preservation of native forests, covering over 90% of the area, but also a significant expansion of agriculture and livestock farming, approximately 5% over 38 years (a growth of over 56,000 hectares). Non-vegetated areas increased about sevenfold, indicating urbanized expansion. The analysis of economic activities demonstrated that, despite agricultural growth, local economic development did not proportionally follow this expansion. Consequently, GDP per capita showed a brief increase but did not align with the scale of agricultural growth. This study highlights the importance of environmental monitoring and the need for sustainable policy-making to guide territorial management in the municipality.
