Résumé

O município de Brasil Novo, localizado na fronteira agrícola da Amazônia, experimenta significativas mudanças em sua cobertura do solo, impulsionadas principalmente pela expansão da pecuária e do cultivo de cacau. Através da análise de imagens de satélite Landsat 8 e do produto da ESA WorldCover 2020, combinada com informações climáticas e socioeconômicas, este estudo investigou as dinâmicas do uso da terra no período de 2015 a 2023. Os resultados revelaram uma redução substancial da cobertura florestal, com a expansão das áreas de pastagem como principal motor do desmatamento. A análise temporal do Índice de Vegetação por Diferença Normalizada (NDVI) indicou variações interanuais na cobertura vegetal, associadas a eventos climáticos extremos e à pressão antrópica. Embora o município ainda mantenha 43,8% de cobertura florestal, com destaque para a Terra Indígena Arará, a pressão sobre os recursos naturais exige a implementação de políticas públicas e práticas de manejo sustentável para mitigar os impactos ambientais e garantir a conservação da biodiversidade amazônica.
