Assessment of Water Use Efficiency Indices in Selected Plains of Fars Province, Iran

This paper aimed to evaluate Water Use Efficiency (WUE) indices for crops and horticulture productions. In doing so, after gathering data from 164 farmers, we investigated water withdrawal cost indices and monetary return per cubic meter of water through two econometric and managerial approaches. Besides, water shadow pricesand dry matters of per cub meter of water were calculated. The results revealed that the average monetary return per cubic metre of water is 3875.4 IRR 1 (0.134 USD) and cost per cubic metre of well water equals 839.3 IRR (0.029 USD), four times more than the value of some current development projects of water resources. Finally, according to the findings, we suggested a corrected price trade term to adjust water monetary return indices. Control policies and government participation in funding of artificial recharge of undergorund aquifers projects were recommended as well.
