Description / Abstract

This report reviews 23 studies that have applied cost benefit analysis (CBA) to assess community-based disaster risk reduction and climate change adaptation projects. The review shows that CBA at a community level is adding value to our understanding of the effectiveness of efforts to reduce climate and disaster risk – often with unexpected findings. This report identifies common methodological approaches and differences in the application of CBA and also highlights methodological limitations. Finally, after summarizing gaps in our understanding, the report concludes with key messages emerging from the study and outlines recommendations for addressing gaps and moving the agenda forward.
