Resumen

El municipio de Brasil Novo, ubicado en la frontera agrícola de la Amazonía, experimenta cambios significativos en su cobertura del suelo, impulsados principalmente por la expansión de la ganadería y el cultivo de cacao. Mediante el análisis de imágenes satelitales del Landsat 8 y el producto ESA WorldCover 2020, combinado con información climática y socioeconómica, este estudio investigó las dinámicas del uso de la tierra en el período 2015-2023. Los resultados revelaron una reducción sustancial de la cobertura forestal, con la expansión de las áreas de pastizales como principal motor de la deforestación. El análisis temporal del Índice de Vegetación por Diferencia Normalizada (NDVI) indicó variaciones interanuales en la cubierta vegetal, asociadas a eventos climáticos extremos y a la presión antrópica. Aunque el municipio todavía mantiene un 43,8% de cobertura forestal, destacando la Tierra Indígena Arará, la presión sobre los recursos naturales exige la implementación de políticas públicas y prácticas de manejo sostenible para mitigar los impactos ambientales y garantizar la conservación de la biodiversidad amazónica.

Palabras-clave: Amazonía, NDVI, teledetección, cambio climático, ganadería, uso de la tierra.
