Knowledge and Concern for Sea-Level Rise in an Urban Environmental Justice Community

Perceptions of sea-level rise in urban, environmental justice (EJ) communities are poorly understood. These communities' long-term vulnerability may increase as a result of the interaction of sea-level rise and legacy pollution. This article presents research on experience and perceptions of sea-level rise, flooding, legacy pollution/contamination, and health in an EJ community in northern Delaware. The community is in close proximity to documented brownfields and other hazardous sites, and is located where there are long-term projections of water inundation due to sea-level rise. Researchers administered quantitative surveys at local events that measured knowledge and concern for these issues; conducted focus groups that enabled a deeper understanding of survey results; and examined community perceptions relative to existing policy tools, including sea-level rise inundation maps and documentation of contaminated sites. The mixed-method approach created a baseline of perceptions on pollution, flooding, a health-environment connection, and sea-level rise. Key findings include the value of experiential knowledge of local flooding to improve efficacy of future policy prescriptions, and how a lack of knowledge of sea-level rise, coupled with great concern for it, might be explained by longtime familiarity with flooding issues in the community.
