Recognizing the effects of climate change on the frequency of storms and rainfall intensity, design criteria for flood control structures should be revisited to ensure that capacities of structures are adequate to handle the expected increase in floodwater volume. Protocols on dam-water release during typhoons should also be reviewed. Moreover, downstream interventions will have to be complemented by upstream activities such as watershed management to minimize siltation which significantly reduces effectiveness of flood control structures, especially when left unabated.
The adoption and mainstreaming of the eco-efficiency concept in water infrastructure is an example of such an adaptation strategy. Excess water during rainy seasons can be impounded, stored and then released for future use in sectors such as irrigation and water supply.
Equally important are immediate post-disaster response and interventions. LGUs and implementing agencies alike are encouraged to adopt a proactive approach in the conduct of DRRM. Emphasis shall be given to preventive measures and structures as well as in raising disaster-preparedness among stakeholders to minimize damage to lives and properties should a natural disaster occur. Furthermore, nonstructural measures such as flood forecasting and warning systems as well as LGU preparedness plans, should be developed accordingly.
