This study presents a rapid approach to assessing disaster resilience in Florida, particularly regarding Hurricane Helene (2024). The Disaster Resilience Index (DRI) developed in this paper evaluates the preparedness and adaptive capacities of communities across counties in Florida, identifying the most resilient areas based on three key variables: population size, average per-person income, and the Social Vulnerability Index (SVI).
The results highlight that counties with high income and lower population densities, such as Monroe and Collier, exhibit greater resilience. In contrast, areas with larger populations and higher social vulnerabilities, like Collier, Monroe, Sarasota, and Charlotte counties, are at greater risk of damage. The DRI provides actionable insights for anticipatory measures and resource allocation, contributing to improved disaster management planning.
The study also compares the DRI with the FEMA National Risk Index (NRI), noting that the DRI's focus on resilience and recovery capacity complements the NRI's broader risk assessment. By combining these tools, policymakers can adopt a more holistic approach to address both immediate risks and long-term recovery potential.
The key findings reveal that while higher income might imply a capacity for quicker recovery, a county's relatively moderate social vulnerability and lower population density can ultimately diminish its DRI. These combined factors render some counties, like Monroe and Collier, both highly vulnerable and less resilient, underscoring the importance of integrating resilience-focused metrics like the DRI to enhance disaster preparedness and recovery strategies.
