Abstract

ABSTRACT Environmental Impact Assessment (EIA) and Risk Assessment (RA) are critical tools for assessing and managing environmental impacts and risks of projects. However, their integration remains a challenge. This study examines how EIA practices account for risks in evaluating the environmental feasibility of mining dam projects in the state of Minas Gerais, Brazil. We analyzed licensing processes for projects approved between 2004 and 2022, using data from the state’s environmental agency. Methods included documentary and content analysis of Environmental Impact Statements (EIS) and review reports. Among the 25 cases analyzed, most focused solely on risk control without performing RA. Only two cases included RA, and two others lacked any risk-related information. Review reports revealed that only two went beyond considering risk control when assessing environmental feasibility. This suggests decision-making relies on a narrow focus on risk control. Furthermore, there is a misalignment between the EIS content and the criteria for project acceptability in review reports. Finally, we explore how politicization may undermine the EIA’s role in objective, and evidence-based decision-making. These findings underscore the superficial and fragmented approach to addressing environmental risk in mining dam assessments in Minas Gerais.
