The Post Disaster Needs Assessment, PDNA, is a joint product of the European Union, the World Bank and the United Nations Development Group, drawn up as an effort to harmonize post crises assessments, including those associated to disasters triggered by natural hazards.

Learning objectives

At the end of this course, you will be able to:

  • Understand the PDNA methodology and apply it to one key sector or cross-cutting issue.
  • Conduct the cost estimates of damage, loss and recovery needs for each sector of analysis.
  • Understand the importance of conducting the human and macroeconomic impact assessment.
  • Learn how the PDNA informs the Disaster Recovery Framework, DRF.


This course is suitable for staff of any level of seniority, with general background on Disaster Risk Management and some experience in post-disaster recovery, either assessments, planning or actual implementation. External participants interested in learning the PDNA methodology will need to be sponsored by one of the UN Agencies, Funds or Programs, the WB or the EU.

  2. Context, baseline information, identification of the disaster effects and costing the disaster effects (concepts of Damage and Loss)
  3. Human Impact and Macroeconomic Impact
  4. Recovery needs and it prioritization, recovery strategy and transit to the Disaster Recovery Framework
