The purpose of this study was to evaluate climate change vulnerability over the agricultural infrastructure in terms of flood anddrought using principal component analysis. Vulnerability was assessed using vulnerability resilience index (VRI) which combinesclimate exposure, sensitivity, and adaptive capacity. Ten flood proxy variables and six drought proxy variables for the vulnerabilityassessment were selected by opinions of researchers and experts. The statistical data on 16 proxy variables for the local governments(Si, Do) were collected. To identify major variables and to explain the trend in whole data set, principal component analysis (PCA)was conducted. The result of PCA showed that the first 3 principal components explained approximately 83 % and 89 % of the totalvariance for the flood and drought, respectively. VRI assessment for the local governments based on the PCA results indicated thatprovinces where having the relatively large cultivation areas were categorized as vulnerable to climate change.
