A Fuzzy ANP-Based Approach to Evaluate Region Agricultural Drought Risk

AbstractWith the global climate change, drought disasters occur frequently and caused huge economic loss. In this paper, a drought risk assessment model based on fuzzy Analytic Network Process (ANP) method is put forward. ANP is an extension of AHP method and can more reasonably reflect the interdependence between the same layers of evaluation index system. The index system of agricultural drought risk assessment is established. An application is demonstrated by Hunan Province agricultural drought in China from 2007 to 2009. The result shows that the method is effective for agricultural drought risk assessment
