Climate Change, Environmental Disasters, and Health Inequities: The Underlying Role of Structural Inequalities.

PURPOSE OF REVIEW

We review and analyze recent literature in public health, urban planning, and disaster management to better understand the relationships between climate change, natural disasters, and root causes of health disparities in the USA.

RECENT FINDINGS

Existing scholarship establishes clear linkages between climate change and increasing occurrences and severity of natural disasters across the USA. The frequency and types of disasters vary by region and impact both short and long-term health outcomes. Current research highlights health inequities affecting lower income and minoritized communities disproportionately, but data-driven studies critically examining the role of structural inequalities in climate-induced health disparities are sparse. Adding to the body of knowledge, our conceptual framework maps how long-standing structural inequalities in policy, practice, and funding shape vulnerability of lower-income, racially and ethnically marginalized individuals. Vulnerability follows three common pathways: disparities in "exposure", "sensitivity", and "resiliency" before, during, and after a climate disaster. We recommend that future research, policy, and practice shift towards solutions that unearth and address the structural biases that cause environmental disaster and health inequities.
