As of my last knowledge update in January 2022, the United Nations Office for Disaster Risk Reduction (UNDRR) plays a crucial role in promoting a global culture of disaster risk reduction. It operates under the United Nations umbrella and works towards enhancing the resilience of communities and nations to disasters. UNDRR supports the implementation of the Sendai Framework for Disaster Risk Reduction, a global agreement adopted in 2015 that outlines priorities and actions to reduce disaster risk.
