Megadisaster knowledge notes

September 2012

 

Learning from Megadisasters, a knowledge-sharing project sponsored by the Government of Japan and the World Bank, is collecting and analyzing information, data, and evaluations performed by academic and research institutions, nongovernmental organizations, government agencies, and the private sector, all with the objective of sharing Japan's knowledge on disaster risk management (DRM) and postdisaster reconstruction with countries vulnerable to disasters. The first phase of the project delivered a set of 32 knowledge notes grouped into six thematic clusters: 1) structural measures, 2) nonstructural measures, 3) emergency response, 4) reconstruction planning, 5) hazard and risk information and decision making, 6) economics of disaster risk, risk management, and risk financing. The notes analyze and synthesize what worked, what did not, and why in the response to the March 11, 2011, earthquake and tsunami, offering recommendations for developing countries that face similar risks and vulnerabilities.
