MULTI-CRITERIA GAP ANALYSIS OF FLOOD DISASTER RISK REDUCTION MANAGEMENT IN METRO MANILA, PHILIPPINES

Abstract

Identification of priority areas for flood disaster risk reduction (FDRR) management is critical and often tedious to both planners and decision-makers. Requests for additional resources, infrastructures and capability enhancement may require a quantifiable basis for budget allocation. In Metro Manila, Philippines, flooding is a perennial problem, thus requires a regular assessment of FDRR management. This study provides a simple approach to address this requirement using a multi-criteria gap analysis method. This is demonstrated using the results of the assessment made by the local government units (LGUs) in Metro Manila at the aftermath of an extreme flood event in 26 September 2009. Results show that gaps ranging from very small to medium-scale exist in the management system of the LGUs. Serious attention must be given to land use planning and flood mitigation measures. Flood hazard mapping should also be a priority in most local government units. Efforts must also be made to improve flood warning dissemination.
