This case study aims to address calls for more rigorous evidence-based research on the costs and benefits of disaster risk reduction (DRR) interventions at the community-level. The International Federation of Red Cross and Red Crescent Societies (IFRC) is attempting to narrow this gap by building an evidence-base for DRR activities which are replicable, scalable and applicable in various settings and contexts. It will highlight the impacts, costs, benefits and economic efficiency of community-based DRR. This study was undertaken to assess the impact and cost-benefit analysis (CBA) of DRR programming in three communities in the Red Sea State of Sudan. Published in 2012.
