Disaster Risk Reduction (DRR) is the systematic development and application of policies, strategies and practices that minimize vulnerabilities and disaster risks throughout a society. Mercy Corps believes that DRR is an essential part of our mission to help people build secure, productive and just communities. We therefore incorporate DRR strategies in our assistance work to help communities become more resilient to hazards, and thus reduce the likelihood that their development may be undermined by one or more disasters.
