Featured PDNAs

PDNA is a government-led exercise, with integrated support from the United Nations, the European Commission, the World Bank and other national and international actors. A PDNA pulls together information into a single, consolidated report, information on the physical impacts of a disaster, the economic value of the damages and losses, the human impacts as experienced by the affected population, and the resulting early and long-term recovery needs and priorities.
