The Amazon has been experiencing an intensification of deforestation and environmental degradation processes, with direct impacts on biodiversity, climate regulation, and Indigenous territories, especially in regions under pressure from agricultural expansion. In this context, the present study aimed to analyze the spatiotemporal dynamics of land use, land cover, and vegetation vigor in the Anambé Indigenous Land, located in the municipality of Moju, Pará State, Brazil. To achieve this, a multitemporal remote sensing approach was applied, integrating Landsat and Sentinel-2 imagery for the calculation of the Normalized Difference Vegetation Index (NDVI), together with thematic land use and land cover data from the MapBiomas Project for the period between 1985 and 2024. The combined analysis allowed the identification of stable vegetation vigor and predominance of forest formations in the core of the territory, while more significant land cover changes were concentrated along the borders, particularly in the southern portion, where expansion of pasture areas, non-vegetated surfaces, and possible access routes were observed. These findings indicate internal ecological integrity associated with increasing peripheral anthropogenic pressure. It is concluded that although the Anambé Indigenous Land remains largely preserved, its long-term stability depends on continuous monitoring, control of external pressures, and the strengthening of Indigenous territorial governance, contributing to climate change mitigation and biodiversity conservation in the Amazon.
