Economic Analysis of Adaptation Options in Honda Bay, Puerto Princesa City, Philippines

by Patrick A. Regoniel, Melissa Theodora U. Macasaet, and Nelly I. Mendoza

This research project identified and assessed the climate change impacts (i.e., sea level rise), and conducted a cost-effectiveness analysis (CEA) of the climate change adaptation (CCA) strategies of two coastal villages, namely, Babuyan and Binduyan located in Honda Bay, Palawan, Philippines.The results of the CEA in Babuyan showed that mangrove reforestation would be the most cost-effective strategy for protecting households and properties from strong waves and storm surges. Mangroves thrive well in this village; thus, it can effectively minimize sand erosion in the coastal zone. Implementing an information campaign and building a temporary evacuation center in the coastal village would also be cost effective for protecting households from flooding. Meanwhile, the results of the CEA in Binduyan showed that mangrove reforestation would be less effective because mangrove areas for reforestation in Binduyan are limited; the sandy soil and inherently poor nutrient content of the soil in the village would not allow mangroves to thrive. Seawall construction appeared to be more practical with the lowest cost effective ratio.Upon validation of the CEA results, key officials in the barangays preferred CCA strategies that would be easy to implement, most feasible, or within their means to fund like mangrove reforestation.
