Vulnérabilité aux inondations et changements climatiques

The study examines flood risk in Windsor, Ontario, by combining geospatial hazard data with socioeconomic indicators. It finds that while riverine flood risk is relatively evenly distributed across social groups, pluvial (surface) flood risk is significantly higher for Black households, Indigenous people, and other visible minorities. The authors argue that traditional risk assessments focusing only on physical exposure overlook these environmental injustices, and recommend that mitigation resources and communication strategies be targeted toward socioeconomically vulnerable communities to improve cost-effectiveness and equity.

• In the Windsor Census Metropolitan Area (CMA), 22.6% of residential properties (26,722) are exposed to riverine flood hazards, while 16.6% (19,582) are exposed to pluvial flood hazards.
• There is a statistically significant correlation between socioeconomic vulnerability and pluvial flood risk, with Black households, Indigenous populations, other visible minorities, and single-parent families being disproportionately exposed.
• Unlike pluvial risks, riverine flood exposure in the Windsor CMA does not show significant racial or social disparities; for instance, Black households were found to have a lower risk of riverine flooding.
• Integrating socioeconomic vulnerability into risk assessments reveals 'hot spots' and environmental injustices that traditional methods—which focus only on physical exposure and hazards—fail to capture.
• The authors recommend that flood risk communication and awareness campaigns be specifically adapted for the most vulnerable populations due to the identified correlations between marginalization and flood risk.
• Beyond physical infrastructure, the study suggests that social programs targeting determinants of vulnerability—such as low income, unemployment, and high housing costs—can reduce overall flood risk.
