Flooding is a growing threat to all Canadians. But certain social groups are particularly vulnerable, due to factors like low income, mobility constraints and physical disabilities. For example, women, Indigenous communities, seniors and newcomers are more susceptible to the negative impacts of environmental hazards. P4A is working with the Canadian Red Cross and other partners to develop, refine and test a social vulnerability index. This tool will help policy makers and flood management practitioners pinpoint the groups that are disproportionately impacted and develop highly targeted outreach strategies that boost awareness and encourage preparedness among Canada’s vulnerable populations. The project will also explore, through surveys and focus groups, how to best raise awareness about natural hazard risks and to encourage Canadians from vulnerable populations to prepare for these hazards.
