Abstract

Decision makers' objective in selecting different cropping activities usually isn't a specific object and they must establish a balance between outcomes of conflicting and competing objectives. This paper introduces a method for driving a multi-objectives cropping pattern in WATER resources management of Zayandeh Rud Basin by using researches, statistical and survey data. The framework of this method was FUZZY compromise non-linear programming (FCNLP) in which optimal irrigation depth was obtained by SWAP model at different SALINITY conditions. Results showed that although the economic benefit of this model was set at current crop pattern, but this model also release 99.2 and 39.1 percent of two objectives' ideal levels including WATER use minimization and gross margin constancy maximization, respectively, at zero SALINITY condition. It will release 76.6, 14.8 and 98.8 percent at 4 dS m-1 SALINITY level and 97.7, 14.3 and 2.2 percent at 7 dS m-1 SALINITY level, respectively for minimizing RISK, maximizing EMPLOYMENT and minimizing urea fertilizer objectives' ideal levels. These levels have been obtained by changing areas of crops including wheat, alfalfa, sugar beet, rice and vegetables and change in irrigation depth and fertilizer use. As a result of these changes, FUZZY composite distance would be maximized and 47.5, 41.2 and 41.1 percent of total ideal levels, respectively at zero, 4 and 7 dS m-1 SALINITY levels would be released by considering the objectives' related weight of studied decision makers. This approach was diagnosed as superior strategy compared to other ones which followed individual goals including maximum production efficiency and profits, with or without change in the crop pattern and suggested to test at the farms level of basin.
