For more than three decades, the Bangladesh Red Crescent Society (BDRCS) has been aiming to reduce this vulnerability by building up local disaster preparedness capacities and by applying numerous tools to reduce risks. Since 1996, it has been running a programme in flood-prone communities with the support of the International Federation of Red Cross and Red Crescent Societies (IFRC) and various donors. This report contains the results of an evaluation that focussed on the programme between 2006 and 2011. The evaluation was commissioned by the IFRC chiefly to measure the impact the programme has generated, to review its efficiency through a cost-benefit analysis (CBA), and to identify lessons learnt that enable enhancements in future risk reduction programming.
