Assessment of Climate Impacts, Vulnerability, and Adaptation Strategies in the Coastal Areas of San Juan, Batangas, Philippines

by Shaneil Ramos-Dipasupil, Imelda Delos Reyes, and Frank Ilustrado

This research identified the impacts of climate change, assessed the vulnerability of the residents of the chosen coastal sites, and analyzed the economic values of their adaptation strategies. A total of 300 respondents were interviewed in San Juan, Batangas, Philippines. The CEA showed that among the planned adaptation options, mangrove reforestation would prevent coastal erosion at the least possible cost. To save households from the effects of typhoon and flooding, the combined option of setting up an integrated drainage/flood control system and diversifying the livelihood options of the residents were the more cost effective. The most preferred autonomous adaptation during and immediately after a flood and typhoon event is to improve or modify houses to make them more resilient to typhoons. Those against coastal erosion prefer preparing for evacuation. The respondents preferred permanent relocation should efforts to improve their houses prove to be futile. Local government officials are able to develop policies and programs to cope up with climate change effects. However, such policies and programs are difficult to implement due to inadequate financial resources and lack of cooperation from community residents. Also, local officials find environment related programs difficult to monitor and implement consistently.
