Health impact assessment in the process of implementation of hydroelectric plants: methodological contributions

Abstract Health Impact Assessment (HIA) is defined by the World Health Organization as a methodology that encompasses the identification, prediction and evaluation of expected changes in health risks. Objective: to analyze the contributions of experts on the stages of HIA. Research was carried out with Brazilian specialists on the stages of HIA with regard to the areas where hydroelectric plants are located using an electronic platform. Eighteen specialists from eight higher education institutions in five Brazilian states participated in the study. They indicate that the following aspects must be observed in the HIA: the need to create interdisciplinary and multiprofessional teams; participation of the affected population at all stages; special attention to mental health; and consider the scientific evidence. These aspects contribute to qualify the HIA stages in the implementation and monitoring of new hydroelectric projects.
