Impact of Climate Change on Disaster Risk Reduction
Overview
> Jump to impact by region
Climate change impacts are expected at various geographical scales, locations, and sectors. Implications for disaster risk management include changes in the magnitude and frequency of climatic extremes, as well as of environmental and socioeconomic conditions, which influence vulnerability to natural hazards. It is necessary to adopt risk management approaches that address current vulnerabilities to natural hazards and reflect changes in environmental conditions over time.
Potential adaptation measures include, for example, improving warning and preparedness mechanisms, planning land-use and urban infrastructure from a climate-sensitive perspective, and developing more resilient water supply systems. The development of public-private partnerships to incorporate risk management into project planning and implementation can help reduce the potential impacts of climate variability and change.
Impact by region
The map above indicates regions at high risk of fatalities from a range of climate-related impacts. For large areas of Africa, drought and hydro-related impacts appear as the primary risk to human life. In many parts of India, China, and Brazil, hydro impacts account for higher risks.
