Learning from megadisasters: the Great East Japan Earthquake

In this report, Japan and the World Bank partner to share knowledge on disaster risk management with countries around the world. The Knowledge Notes that make up the main body of this report were built around the disciplines employed in the traditional DRM cycle. Grouped into six clusters that track that cycle, the Knowledge Notes treat structural measures (cluster 1) and nonstructural measures (cluster 2) as preventive options. They also cover the emergency responses put in place after March 11 (cluster 3) and describe how the recovery process started (cluster 4). The handling of risk assessment and communication before and after the disaster are the subject of cluster 5. Cluster 6 deals with risk financing, insurance, and fiscal and financial management. This section of the Executive Summary provides the reader with additional information and details about the main findings of the project and the lessons learned from it, following the scheme of thematic clusters used in the Knowledge Notes.

In conclusion, the report asserts that ss the GEJE showed, proactive approaches to risk management can reduce the loss of human life and avert economic and financial setbacks. To be maximally effective, and to contribute to stability and growth over the long term, the management of risks from natural disasters should be mainstreamed into all aspects of development planning in all sectors of the economy
