United Nations Office for Disaster Risk Reduction (UNDRR)

Envisioning a world where disasters no longer threaten the well-being of people and the future of the planet, UNDRR leads global efforts to reduce disaster risk, build resilience, and advance the Sendai Framework. Through WHCA, UNDRR strengthens national coordination on disaster risk reduction (DRR) and helps countries understand and manage water-related risks, by improving access to reliable risk data, aligning climate, water, and DRR governance, and promoting inclusive, locally driven approaches. UNDRR’s work makes early warning and early action timely, trusted, and tied to long-term resilience planning. As most climate-related disasters are driven by water – too much, too little, or too polluted – UNDRR helps protect vulnerable communities and guide investments that reduce risk, safeguard water security, and build climate resilience.
