Climate change is the most recent crisis of global impact, and can be most detrimental to developing countries. Southeast Asia, in particular, has been noted as one of the regions most vulnerable to climate change. The objectives of the study were to measure the vulnerability of communities to climate change and to produce maps of each community’s relative vulnerability with respect to the commune and the agricultural sector. Three vulnerability determinants—exposure, sensitivity, and adaptive capacity—and their respective indicators were determined. Exposure refers to damage potential while sensitivity is determined by the interaction of environmental and social forces. Finally, adaptive capacity is shaped by various social, cultural, political and economic forces. The overall index of climate change vulnerability was calculated using a compromise among the three identified indices and ranked to identify the most vulnerable communes. Using GIS software, overall vulnerability maps were produced. Results showed that mostly lowland and coastal areas are greatly affected in all the vulnerability determinants.
