Abstract

Occurrence of frequent droughts along with the current global energy crisis calls for attention to efficient use of water resources and improvement of water productivity level. Also, when other production inputs are used, the relationship and interaction between those inputs and water play important roles and should be considered in research. In this study, water use efficiency is investigated from an economic perspective. Hence, in order to assess wheat technical efficiency and water use efficiency, data envelopment analysis was used. To this end, information of 150 wheat beneficiaries in Zarghan, Fars province, was used in 2010-2011 crop season. The results showed that the mean water use efficiency in the region was very low and about 32 percent. Also, according to the results of T-test used to compare the water use efficiency among input-efficient and input-inefficient group, it was revealed that the mean water use efficiency in efficient producers was significantly more than inefficient farmers. Finally, policy recommendations for increasing water use efficiency in producing wheat in the region and improving technical efficiency is presented.
