Abstract
Disaster risk hinders economic development in developing countries. Flooding in particular is a dominant hazard that significantly affects the economy. Increasing ex-ante investment in DRR is essential to reverse the downward trend. Inter-agency collaboration is crucial for effective DRR practices. However, some governments may be hesitant to work with other stakeholders. This study aimed to understand the problem structures of inter-agency collaboration in ODA programmes, using the case of the ODA programme in the Philippines. This study identifies that the lack of inter-agency collaboration occurs in three different form types: (i)intra-work type; (ii)inter-work type (handover); and (iii)inter-work type (complementarity). Therefore, it is likely that the ODA programme for flood risk management will be managed in silos, leading to partial optimisation. To achieve success in project and programme management (P2M), it is imperative for the donors to analyse gaps derived from the different legislative frameworks and institutional cultures (profiling), redefine the mission of the programme (programme strategy), and ensure continued management of a platform that spans relevant projects (platform).
