This research aimes to evaluate the lifestyles of the ribeirinhos who are affected by the Belo Monte Dam, in Altamira, in the state of Pará, as well as to analyze the use of plants and the local knowledge associated with them to gain a perspective of the changing social and environmental scenarios. We interviewed 60 family units of ribeirinhos affected by Belo Monte. A non-probability sampling was used and the data collection was done through semi-structured interviews, participant observations, guided tours and botanical collection. The data was interpreted qualitatively and quantitatively using the following indices: Total Species Diversity, Total Species Equitability and Value of Importance. Changes in the riverside ecosystem, caused by Belo Monte, were revealed by the families. They highlighted transformations in the water movement, proliferation of aquatic macrophytes and suppression/flooding of coastal vegetation. The territorial displacement created different social profiles which can be categorized in five social typologies formed by the reterritorialization. The survey of the most used plants, before and after Belo Monte, showed 143 species, distributed in 52 botanical families and classified into six categories of use: feeding (88), medicinal (69), fish bait (19), mystical use (7) and utensils (1), where 29% had multiple uses. The strong tradition and dependence that the families of the Xingu keep with nature was emphasized in this study. These points are indispensable for the reproduction of social and community life, exchanges and experiences with plants. They represent repertoires of learned and transmitted knowledge through traditions which are constantly threatened by the profound social, environmental, economic, and cultural changes.PPGCA - Estudos de ecossistemas amazônicos
