Abstract

The present study evaluates the water shortage indices in the agricultural sector of Jiroft Plain, taking into account the framework of water footprint during the 2008 to 2019. In this study, water stress, agricultural water stress, blue water scarcity, water self-sufficiency, water dependency and water poverty indices were evaluated. The results showed that the annual average of agricultural water resources is 1425 MCM, and the amounts of green and blue water resources are 11 and 1413 MCM, respectively. The annual average agricultural water footprint of Jiroft Plain is 354 MCM. The share of blue, green and gray water footprint is 40, 14 and 26%, respectively. The average water stress index is 37%, which shows that the moderate water stress in Jiroft plain. The average AWSI and BWS is 0.84 and 0.77, respectively, which are located in the class with high stress. The water self-sufficiency and dependency are 89% and 11%, respectively, which indicates high self-sufficiency and low dependency of the study area in terms of importing agricultural products. The high water self-sufficiency index despite the lack of rainfall in Jiroft Plain has caused high water poverty in the region. The most important reason for the high WSS is the high diversity of agricultural products in the food basket of this region. As an example, citrus fruits, dates, wheat, barley, potatoes and onions are cultivated in Jiroft plain.
