Abstract

Sustainability of water resources has the most important role in agricultural systems sustainability and is dependent on the pattern of crops. In this study, optimal cropping pattern in Orzooeye plain, Kerman was determined. The cross section data of 2013-2014 were used for the analysis. The main aim of this study is to find the optimal cropping pattern that maximizes the gross margin per cubic meter of water consumption and reducing consuming of water in achieving sustainable agriculture. Therefore, fuzzy fractional programming was used and compared with the current cropping pattern and linear programming. Results showed that the optimal cropping pattern using the fuzzy fractional programming to achieve sustainability is different with the current cropping pattern and linear programming. Despite the reduce in total gross margin in the fuzzy fractional programming model, gross margin per cubic meter of water is increased by 10 percent. This means that maximize income from the cultivation of crops with respect to the sustainability of water resources and water use minimize are benefit for community.
