TRANSCRIPT
Integration of Flood Control and Basin Development in the Cagayan River Basin
Disasters have occured frequently in the Cagayan river basin : Disaster = Hazards�~VulnerabilityHazards : Flood, Sedimentation and Bank Erosion, Typhoon, DroughtVulnerability : Damage of Casualty and Assets, Low Productivity, Lack of Integrated Organization and Institution, and Low Capability
Target in Year 2020
