Drought is an insidious hazard of nature. It is often referred to as a ''creeping phenomenon,'' and its impacts vary from region to region. Studies show that the best approach to managing drought is to apply a comprehensive drought management plan. This system necessitates collecting reliable information to make decisions to decrease the risk and damages caused by drought. Therefore, the first step of the comprehensive drought management is accomplished by preparation of the drought vulnerability map. The main object of this study was to provide for agriculture drought vulnerability mapping for Taft town located in Yazd Province, Iran. To do so, with regard to factors affecting on agricultural drought, maps were prepared for each factor and analytic hierarchy process technique was applied to determine the importance of each map as an input parameter on agricultural drought vulnerability. All input maps and the output of this research, an agricultural drought vulnerability map, were provided and analyzed by geographic information systems.Then, to evaluate and validate how accurately the vulnerability map shows the degree of proneness to agricultural droughts, some ground control points (GCP) were taken into consideration. Results indicated that there is a good agreement between agricultural drought vulnerability map and GCPs in many cases. Also, results showed that mountainous regions of the study area are more vulnerable to agriculture droughts compared with plains. These results can be helpful for decision makers to mitigate agricultural drought impacts over the region, although implementing a drought risk management plan requires a detailed study covering different aspects of drought.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
