Grandes hidrelétricas na Amazônia: impactos no recurso pesqueiro e na pesca artesanal, desafios e lições aprendidas na bacia do Rio Madeira

As consequências socioecológicas da implantação de grandes empreendimentos hidrelétricos são claras e transcendem fronteiras geopolíticas e disciplinares. Este trabalho sintetiza e compartilha relatos de profissionais de diversas áreas e populações atingidas por barragens hidrelétricas construídas na bacia do Rio Madeira. Os depoimentos, discussões e abordagens participativas, evidenciaram a necessidade de conexões e cooperação entre diversos atores, para trabalharmos na solução de problemas comuns gerados por grandes empreendimentos, com destaque para a gestão de recursos pesqueiros e pesca artesanal. A abrangência das percepções e experiências de vários atores podem contribuir para mitigação de impactos, por meio da convergência de conhecimentos e identificação de necessidades comuns

Mapping research on hydropower and sustainability in the Brazilian Amazon: advances, gaps in knowledge and future directions

In the last twenty years, multiple large and small hydroelectric dams have begun to transform the Amazonian region, spawning a growing volume of academic research across diverse disciplinary and interdisciplinary fields. In this article, we offer a critical review of recent research related to hydropower and sustainability with a focus on the Brazilian Amazon. We revisit the sustainability concept to include the contribution of various knowledge fields and perspectives for understanding, managing and making decisions about social-ecological systems transformed by dams. We conducted a literature review in Web of Science of academic publications centered in the past 5 years (2014–2019), on diverse aspects of hydropower planning, construction, operation and monitoring in the Brazilian Amazon. We present results of a co-occurrence network analysis of publications, highlighting bridging fields, network disconnections, and opportunities for interdisciplinary research. Finally, we report recent advances in the understanding and management of social-ecological systems in Amazonian watersheds, including biophysical, socio-economic, governance and development processes linked to hydropower planning and implementation. This review identifies knowledge gaps and future research directions, highlighting opportunities for improved communication among scientists, practitioners, decision-makers, indigenous peoples and local communities. © 2019 Elsevier B.V
