The United Nations Office for Disaster Risk Reduction (UNDRR) emphasizes the critical role of disaster data in reducing risks and building resilience. Accurate, timely, and accessible disaster-related data allows governments, organizations, and communities to better understand hazards, vulnerabilities, and exposures, which is essential for effective planning and decision-making. This page highlights the importance of strengthening data collection and analysis systems globally to support evidence-based risk reduction strategies. It also showcases various international and national databases, such as DesInventar and EM-DAT, which compile disaster loss data. These tools help monitor trends, inform policy, and track progress towards the goals of the Sendai Framework for Disaster Risk Reduction. UNDRR supports countries in building their capacity to generate and use disaster data, ensuring that risk knowledge becomes the foundation for sustainable development and climate resilience.
