Learning through Philippines Flood Risk Management Approaches

Background: The frequency of large-scale natural disasters has increased in recent years, as is evident from the rise in the number of disaster events, and the severity and scale of their impact. Immediate action is required to counteract the growing disaster-related losses. With the direct effect of climate change on disasters, linking disaster risk reduction and climate change adaptation becomes a necessity. To forge a more resilient and inclusive future, the Association of South East Asian Nations (ASEAN), through the ASEAN Committee on Disaster Management (ACDM) Working Group of Prevention and Mitigation, with support from the Government of Japan, through the Japan-ASEAN Integration Fund (JAIF), is partnering with the Institute for Global Environmental Strategies (IGES), the Asian Disaster Preparedness Center (ADPC), and CTI Engineering (CTII), to implement the project “Disaster Risk Reduction by Integrating Climate Change Projection into Risk Assessment”. This is in support of the ASEAN Agreement on Disaster Management and Emergency Response Work Programme 2016-2020, aimed towards “building resilient ASEAN Community to reduce disaster losses and collectively respond to disasters.”

The project is a capacity building initiative directed mainly towards: 1) enhanced ASEAN Member States’ (AMSs) development plans, frameworks, and policies, where Disaster Risk Reduction (DRR) and Climate Change Adaptation (CCA) are mainstreamed, and 2) strengthened capacities of targeted AMS government officials and institutions on flood and landslide risk assessment and risk mapping, with incorporation of climate projection.

Summary

The Philippines is among the most disaster-prone nations in the world. The country, made up of 7,100 islands, is constantly exposed to disasters such as floods caused by typhoon and tropical storms. This is only expected to worsen with climate change. Now, 28 years have passed since the Ormoc tragedy, which was the largest flood in 50 years. November 1991 massive flash floods and mudslides, triggered by heavy rains, killed more than 4,922 people and left 3,000 missing in Ormoc City. 13,760 houses destroyed, more than US$23 million worth of damage to properties and infrastructure. Rehabilitation work have been carried out both by national and local government, three slit dams were constructed to capture floating logs and debris that was blocking bridges. River improvements were also conducted in the midstream to downstream reaches of these rivers. Improvement in the river conditions have been made by Ormoc City through its Flood Management Committee (FMC), including maintenance of the slit dams, removal of the logs and debris, dredging, and cutting vegetation. Under the FMC, easement zones (bank areas) along the rivers have been managed in cooperation with the community (barangay) people, so illegal houses are not built there. These practices have benefited the people of Ormoc City by ensuring additional safety for its people, assets and economy, against floods. There is a need to assess the climate change adaptation potential of these interventions.

ASEAN delegates attended a 4-day study tour, for cross-learning and exchange and on-site exposure to observe/study Philippines’ good practices towards building greater resilience for its people:

- Ormoc flood control projects, including new bridges and slit dams to reduce the damage of floating trees and landslides; widened rivers and diking systems to provide other protective infrastructure and improve draining of the city’s two major rivers.

- City Local Climate Change Action Plan (LCCAP) 2016-2025: 10-year action plan that outlines the city’s specific program and strategies for adaptation to and mitigation of climate change.

- Disaster Risk Reduction and Management Office function and its annual city plan; Geographic Information System (GIS) used by the city government as part of its disaster preparedness response to tropical storm Uring.
