Análise das transformações na Terra Indígena Paquiçamba a partir da construção da Usina Hidrelétrica de Belo Monte/PA

Abstract

Environmental impacts have become the subject of intense national and international debates, in which heads of state and the scientific community discuss the importance of environmental preservation, especially in sensitive areas of the Amazon Biome. This issue becomes even more important when discussing the contributions of indigenous peoples to the preservation of nature, as well as the environmental and social impacts they suffer from the implementation of infrastructure projects. This context includes the Paquiçamba Indigenous Land, where there have been major transformations since the arrival of the Belo Monte Hydroelectric Power Plant. In this sense, the research sought to analyze the geoecological changes suffered in the Paquiçamba Indigenous Land after the installation of the Belo Monte Hydroelectric Power Plant. As a methodological procedure, remote sensing techniques were used to classify, segment and interpret images from the Landsat 5 and 9 satellites in 2011 and 2023. Among the results, it was possible to observe that considerable changes in the landscape were caused by the decrease in water and the increase in exploitation areas, making this an unstable environment for maintaining biodiversity as well as the traditions of the Juruna (Yudjá) indigenous peoples.
