Abstract: The historical context of the region was compared to the results obtained from the set of adopted images. Based on the analyzed documents we can define the main anthropogenic phenomena responsible for the changes in the vegetation cover in the region. We identified the Paraguayan agricultural expansionism and the predominantly agricultural Brazilian migratory movements to the border region between Brazil and Paraguay. The results show that the systematic process of deforestation had already been established before the beginning of the construction of Itaipú. Migratory processes associated with previous factors to the construction of hydroelectric show mainly correlations with the deforestation observed in the region. Furthermore, the analysis verifies the incoherent documentation about the current situation in the protected areas. The conclusions prove the characteristics of the employed method showing that its use is valid in a context of the analysis of the regional development.

Keywords: Land Cover Change, Thematic Map comparison, Itaipú.
