Environmental impacts of hydropower plants in Brazil: identification guide. (English)

Impactos ambientais de hidrelétricas no Brasil: guia de identificação. (Portuguese)

This paper presents a guide for the identification of environmental impacts of hydroelectric enterprises. The qualitative research used the following methods: case studies, systematic literature review (SLR), content analysis, and consultation with experts. Four sources of information were used, including: Environmental Impact Statements (EISs), scientific articles, best practice guides, and expert consultation. All EISs of hydroelectric plants submitted to the Brazilian federal Environmental Licensing between 2010 and 2020 (8 EISs) were analyzed. RSL identified 68 scientific papers eligible for analysis and collection of impacts. The results were compared with Canadian practice and discussed in a virtual workshop of 15 experts. The guide has 90 impacts and can be used by environmental consulting firms and environmental agencies in the preliminary identification of environmental impacts of hydroelectric dams, contributing to the improvement of planning carried out in the EIA scoping stage of future environmental studies of this type.

Este trabalho apresenta um guia para identificação de impactos ambientais de empreendimentos hidrelétricos. A pesquisa qualitativa utilizou como métodos: estudos de caso, revisão sistemática da literatura (RSL), análise de conteúdo e consulta a especialistas. Foram usadas quatro fontes de informação, sendo elas: Estudos de Impacto Ambiental (EIA), artigos científicos, guias de boas práticas e consulta a especialistas. Foram analisados todos os EIAs de hidrelétricas submetidos ao Licenciamento Ambiental federal brasileiro, entre 2010 e 2020 (8 EIAs). A RSL identificou 68 artigos científicos elegíveis para análise e coleta dos impactos. Os resultados foram cotejados com a prática canadense e discutidos em um workshop virtual com a participação de 15 especialistas. O guia apresenta 90 impactos e poderá ser utilizado por empresas de consultoria e órgãos ambientais na identificação preliminar de impactos ambientais de hidrelétricas, contribuindo para o aprimoramento do planejamento realizado na etapa de escopo da Avaliação de Impacto Ambiental (AIA) de futuros estudos ambientais dessa tipologia.
