BackgroundThere are several studies associating the construction of power plants to the increase in deforestation rates. However, there are no case studies analyzing deforestation near power plants, seeking to find a logic of how such deforestation occurs and attributing a statistical correlation with some factors that may mitigate or potentiate such deforestation. This study fills this gap on the scientific literature. Although it analyzes four cases, it is relevant given the lack of publications on this topic.MethodsIn this study, a comparative analysis of deforestation was conducted in the vicinity of four hydroelectric plant projects in the Amazon forest, aiming particularly to identify measures related to the creation of areas of restricted use, protected areas, and indigenous lands, as a way to minimize the predatory occupation around reservoirs.ResultsThe results showed that there is a strong negative correlation between the extension of indigenous lands and protected areas and deforestation in the vicinity of the power plants analyzed, even when they are located in areas with a high level of human occupation. This study also revealed, by Pearson correlation analyses, that there are few pairs of variables whose correlations are weak or very weak. There are predominantly moderate, strong, and very strong correlations.ConclusionsThus, it is suggested that new hydroelectric plant projects in the Amazon should prioritize the creation of areas of restricted use and discourage occupation through settlements and opening of roads, as these variables were determinant for the level of degradation to the environment around the construction works analyzed.
