The purpose of this study was to evaluate climate change vulnerability over the agriculturalinfrastructure in terms of fl ood and drought using principal component analysis. Vulnerabilitywas assessed using vulnerability resilience index (VRI), which combines climate exposure,sensitivity, and adaptive capacity. 17 fl ood proxy variables and 21 drought proxy variablesfor the vulnerability assessment were selected by opinions of researchers and experts. Thestatistical data on 38 proxy variables for the local governments were collected. To identifymajor variables and to explain the trend in whole data set, principal component analysis (PCA)was conducted. The result of PCA showed that the fi rst 5 principal components explainedapproximately 86% and 87% of the total variance for the fl ood and drought, respectively. VRIassessment for the local governments based on the PCA results indicated that provinceswhere having the relatively large cultivation areas were categorized as vulnerable to climatechange.
