Analysis of Barriers on Integrated Flood Risk Management in Metro Manila, Philippines, by Interpretive Structural Modeling Approach

The adaptation of integrated flood risk management (IFRM) approach in the Philippines is a challenging task due to heavy reliance of traditional structural measures in the past. And so, there are critical issues or "barriers" that hamper the adaptation of IFRM. This study presents for the first time a framework in identifying the barriers on IFRM in a case-specific approach focusing on a megacity of a developing country such as Metro Manila, Philippines. Moreover, this framework presents a systematic approach in analyzing the barriers on IFRM by interpretive structural modelling. This study was able to identify a total of 12 barriers that encompasses governance, social, and technological resources aspects in Metro Manila, Philippines. The results show that barriers on the governance aspect are the most influential barriers while barriers on the social aspect have the least influence to other barriers.
