The Amazon has a large amount of water resources, and in Brazilian energy policy
there is interest in the hydraulic exploitation of this region, for purposes of electric
power generation, but these construction cause various social and environmental
effects. In the Environmental Impact Studies and in the Environmental Impact Report
of hydroelectric dams, the access and use of the water resources of the affected
populations are not taken into account. Thus, this thesis aimed to study the water
vulnerability of the populations living in the lake region of Tucuruí Hydroelectric
Power Plant, in the State of Pará (PA). The question that led to the research
hypothesis was: Is water vulnerability a social effect of hydroelectric construction?
The analysis was carried out with the support of Social Cartography and Social
Impact Assessment, associated with the use of the Institutional Analysis and
Development Framework created by Elinor Ostrom, the Qualitative Comparative
Analysis method and the fuzzy logic, operationalized by the software fsQCA 2.0.
Socioeconomic, institutional and environmental conditions were considered as
independent variables (X), in which the precariousness found in these conditions
would reflect the water vulnerability that the residents of the Tucuruí hydroelectric
dam would be exposed. The results confirmed the hypothesis of this thesis where the
construction of the Tucuruí hydroelectric dam caused the water vulnerability of the
inhabitants of the lake to a degree of "partially vulnerable" (0,1), and that the
socioeconomic, institutional and environmental variables are necessary conditions for
explain the phenomenon, however, are only sufficient when analyzed together.
