Roles of Pacific regional organizations in disaster risk management
This report documents the current contributions of Pacific regional organizations to disaster risk management (DRM) and explores the potential for them to play more substantial and active roles in the future. Although regional mechanisms are playing increasingly important roles in DRM, there has been remarkably little research on their contributions and few published studies on their comparative advantages. At a global level, this recent Brookings study sought to address this gap by summarizing the work of more than thirty regional organizations involved in DRM, drawing some comparisons and ge ...
