The implementation of dams in the Amazon threatens fisheries, which can affect the food security of thousands of socially vulnerable families. Though mandatory, compensation for the dam’s impacts on artisanal fishery systems has not achieved its expected outcomes. The environmental impact assessments have been insufficient to inform a systemic evaluation of these impacts. This study proposes a tool for evaluating dam’s environmental impacts on Amazonian artisanal fisheries through an adaptation of the social-ecological systems (SES) framework. This framework was applied to test the impacts of the Estreito and Santo Antônio dams, proving useful, easy to handle, and visually appealing. The tool enabled the identification of missing or incomplete information that should be included or more deeply considered in environmental impact studies. Information gaps were evidenced for both hydroelectric, which may compromise the sustainable management of the activity. A five-step guide to implementing this tool is presented in the final section.
