In many parts of the world, food production is threatened by increasing occurrences of water scarcity. The suggestion of using virtual water trade (VWT) between countries has been put forward to alleviate water scarcity in international trades. In this project, we analyzed the potentials of VWT between provinces of Iran, which is achievable, in part, by structural changes in cropping pattern (SCCP).
Multi criteria decision analysis framework of the ACCP corresponding to the VWT strategy. IRWR= internal renewable blue water resources, IRR= irrigation water requirement, CWP= crop water productivity. Dash lines in the constraint are the factors that were not considered here.
