A joint World Meteorological Organization (WMO) and United Nations Development Programme (UNDP) report has found major opportunities to move from post-disaster response toward proactive, data-driven resilience planning. Titled Mapping the Impact and Informing Economic Resilience: An Analysis of Post-Disaster Needs Assessment (PDNAs), it draws on 91 PDNAs conducted between 2000 and 2024 to analyze losses and damages from tropical cyclones, floods and droughts across Africa, Asia-Pacific, the Americas and Europe.
The report highlights concentrated economic impacts in agriculture, housing and transportation, which “collectively bear the majority of reported losses and damages.” It also exposes large disparities in the quality and extent of disaster impact data and the limited integration of national meteorological and hydrological services (NMHS) into PDNAs – only around 20% of assessments reviewed engaged NMHS.
“The rising frequency and intensity of weather, climate and water-related hazards have cascading impacts on our society, challenging economic resilience and sustainable development worldwide,” writes WMO deputy secretary-general Ko Barrett in the foreword. “This report offers a unique evidence base for understanding the differentiated impacts of hazards across sectors, and provides critical insights into where vulnerabilities lie.”
A central theme is the need to embed resilience in recovery. The analysis warns that rapid rebuilds that merely restore pre-existing conditions can lock countries into cycles of repeated damage. The report recommends aligning reconstruction with national adaptation and development plans, promoting safer construction standards and resilient infrastructure, supporting diversified and climate-resilient livelihoods, and integrating impact-based forecasts and climate services into recovery decisions.
NMHS are identified as critical yet underused partners. The report argues that NMHS data is foundational for early warning, hazard attribution, climate services and risk modeling, and that greater NMHS involvement would transform PDNAs from reactive inventories into forward-looking resilience strategies. It calls for systematic integration of NMHS into assessment processes, increased investment in observation networks and forecasting systems, wider use of socioeconomic benefit analyses, and closer collaboration with sector ministries and local authorities.
UNDP crisis bureau director Shoko Noda frames the report as a practical tool for policymakers: “Governments, donors and partners can use these insights to build safer homes, stronger communities and smarter development. Every investment in resilience today reduces the human and economic costs of tomorrow.”
The paper summarizes five key lessons: sectoral impacts are predictable and preventable (priority sectors: agriculture, housing, transportation); building back better must guide recovery; NMHS must be fully integrated into planning; early warning systems save lives and livelihoods; and standardized hazard and sectoral data is essential for accurate, comparable and actionable impact information.
The report offers a clear, evidence-based roadmap for governments and development partners seeking to reduce future losses and strengthen economic resilience in the face of a changing climate.
