摘要Bangladesh is renowned in disaster risk reduction(DRR)for active involvement of community people and local disaster management institutions in DRR activities.Our study aimed to describe the disaster risk management(DRM)institutions and assess their functioning in six coastal unions across the three coastal zones of Bangladesh.Both qualitative and quan-titative research approaches were used.The study focused on two key local institutions-the Union Disaster Management Committees(UDMCs)and the Cyclone Preparedness Program(CPP)-functioning at the union level in DRM.Such institu-tions have both horizontal and vertical collaborations with other institutions.However,we argue that the UDMCs'external dependencies in their functioning indicate their limited financial and administrative autonomy,which is a barrier to suc-cessfully institutionalizing disaster management.The results show that the CPP is the most successful program,markedly increasing the trust of the people in warning dissemination and evacuation efforts in the event of a cyclone.Although the adoption of decentralized risk management systems has resulted in significant progress in increased rate of evacuation and reduced death rate and damage,lack of funding and equipment,limited coordination between institutions,lack of skilled and knowledgeable workforce,and inappropriate power structures may reduce the effectiveness of DRR activities prior to,during,and following disasters.
