Enhanced Climate and Disaster Risk Assessment (CDRA) is a systematic and science-based process used to identify, analyze, and evaluate the potential impacts of climate change and natural hazards on communities, ecosystems, and development sectors. It integrates historical hazard data with climate projections to better understand current and future risks, particularly those related to flooding, landslides, storm surge, earthquakes, drought, and extreme weather events. By combining spatial analysis, exposure mapping, and vulnerability assessment, the Enhanced CDRA provides a more comprehensive risk profile than traditional hazard assessments.
This approach strengthens conventional CDRA by mainstreaming climate change scenarios, including changes in rainfall patterns, sea-level rise, temperature extremes, and their cascading effects on land use, infrastructure, livelihoods, and social services. It emphasizes the assessment of both physical and socio-economic vulnerabilities, recognizing that risk is shaped not only by hazards but also by governance, land use practices, population characteristics, and coping capacities. This allows planners and decision-makers to anticipate long-term risks and prioritize areas and sectors requiring urgent intervention.
Ultimately, the Enhanced CDRA serves as a critical decision-support tool for resilient and sustainable development planning. Its outputs guide the formulation of risk-sensitive land use plans, zoning regulations, investment programming, and disaster risk reduction and climate change adaptation strategies. By grounding policies and projects in evidence-based risk information, the Enhanced CDRA helps reduce losses, protect lives and assets, and strengthen the adaptive capacity of communities in the face of a changing climate.
