Iran is facings increasing water scarcity because of population growth and geographic located, industrial development as well as climate change. Agricultural is an economic sector and water crisis is the major limiting factor for producing agricultural commodities and food product. Agricultural products sector don’t meet all of its water demand, while 93% renewable water resources in irrigated agriculture are used. In this study, virtual water trade of agricultural crops is assessed in relation to water resources availability, as efficient alternative and water scarcity alleviation in different regions/ provinces of Iran during 1369-1380. Agricultural crops in this study include cereal (wheat, barley, rice and maize), fruits (apple, orange, onion and potato), pulses (beans, chickpea) and pistachio and date. Among these crops, cereal trade cause save the most water resources and pistachio and date trade cause loss the most of water resources at country level. The results of assessing water saving in each province show that Yazd and Gilan are the most water saving provinces and Fars and Kerman are the most water loss provinces, but water saving or water loss without considering the type of virtual water (blue and green) doesn’t provide useful information for surveying increasing/ decreasing trend of water scarcity. Therefore, we distinguished in this study the blue and green virtual water trade of agricultural crops. The results show Gilan and Yazd are the most green and blue virtual water importing provinces, respectively. Lorestan and Mazandaran are the most green and blue virtual water exporting provinces. We also accounted for per capita water resources availability of different provinces/regions to analyze how trade of agricultural crops help improve scarcity situation through the trade of agricultural crops. We found that available water with current trade of agricultural crops in the country, the virtual water trade is increasing water resources availability more than 1.5% in Tehran , Ghom and Yazd . Also per capita renewable water and per capita net Our results at regional level is assessed and the results showed the increasing per capita available water resources increases about 267% in Severity Water Scarce, 35% in High Water Scarce regions, 28% in Water Scarce regions and 1.5% in no-water scarcity regions.
