Abstract
Communities across the world are experiencing a myriad of impacts from intensifying extreme heat, flood, drought, and wildfire events due to climate change. Communities near contaminated sites and waste management facilities may experience further impacts from extreme climate events due to the risk of contaminant releases into the surrounding environment. These overburdened communities are disproportionately impacted by these events due to a combination of economic, health, social, and environmental burdens. Because resources are often scarce for these communities, a dependable, evidence-based approach is needed to assist with prioritizing and targeting resources toward areas that may be impacted the most. Here, we present a conceptual framework for collective understanding of key vulnerabilities and exposure pathways. Indicators and maps were developed to represent contaminated sites, waste facilities, contaminant fate and transport (by air and water), and a range of population sensitivities. This transparent and replicable screening method is based on publicly available data and can be used to identify the communities most vulnerable to extreme climate events. We demonstrate the method in Phoenix and Maricopa County, Arizona (USA), where the approach informed plans for preparedness, response, and recovery. This example highlights how evidence can help decision-makers build their communities’ capacity to address potential future climate risks. Regional, state, and local decision makers can also use this method to develop targeted strategies for preventing adverse health and environmental impacts of disaster-induced contaminant releases.
