Considering the Aramanaí Protected Areas (PA) boundary reduction scenario in Belterra (PA), Brazil, the objective of this paper is to characterize the land use and cover in the PA in 2004, 2014 and 2018, contextualizing its importance as a priority area for biodiversity conservation in the Amazon. A database containing TerraClass Project land use and land cover classes was used to calculate areas, and tabulate the changes that occurred in the period prior to the approval of municipal law no. 237/2017. For further analysis, supervised classification of the image of the Sentinel-2 satellite was performed with enhancement, segmentation and mapping of classes procedures. The results showed forest cover as the main class with more than 60% of the area, and the expansion of built-up areas in the period before the creation of the amending law. It was found that, of the total area excluded, 21.5 km² are plant cover, and that during this period there was acceleration of anthropization at various points. Thus, it is demonstrated that changes occurred in the Aramanaí PA and the importance of systematizing information to support discussions that may contribute to the environmental management in the region.Downloads
