“…The utilities U j relative to any criterion j were normalized into the [0-1] interval, with zero for the more adverse and 1 for the most advantageous result. Following previous studies [30,40] where composite programming and ELECTRE II (Elimination Et Choice Translating Reality) were used, considering the required easiness of discussing the results with the irrigation stakeholders, linear utility functions were adopted [23,24,31]:…”

Abstract:Coping with water scarcity using supplemental irrigation of wheat (Triticum aestivum L.) in the semi-arid northeast Syria is a great challenge for sustainable water use in agriculture. Graded borders and set sprinkler systems were compared using multi-criteria analysis. Alternative solutions for surface irrigation and for sprinkler systems were developed with the SADREG and the PROASPER design models, respectively. For each alternative, two deficit irrigation strategies were considered, which were characterized using indicators relative to irrigation water use, yields and water productivity, including farm economic returns. Alternatives were ranked considering two contrasting priorities: economic returns and water saving. A first step in ranking led to a selection of graded borders with and without precise land levelling and of solid set and semi-permanent sprinkler systems. Precise-levelled borders were better for water saving, while non-precise ones ranked higher for economic returns. Semi-permanent set systems have been shown to be better in economic terms and similar to solid set systems when water saving is prioritized. Semi-permanent sprinkler systems rank first when comparing all type of systems together regardless of the considered deficit irrigation strategy. Likely, border irrigation is appropriate when wheat is in rotation with cotton if the latter is surface irrigated. When peace becomes effective, appropriate economic incentives and training for farmers are required to implement innovative approaches.

“…At present, the farmer's irrigation fees in Hetao are calculated from the field area, and vary from 135 to 190 €/ha including all water cost components and the maintenance of collective infrastructures. The water price established by the Yellow River Commission at sector level is 0.005 to 0.006 €/m 3 . It means that 25-45% of farmer's water fees correspond to the strict payment of water and 55-75% corresponds to the payment of other WUA costs.…”

“…Conditions are appropriate for surface irrigation due to the high charge of sediments of the irrigation water, flat land, and farmer's knowledge, high compatibility with the canal conveyance and distribution network, and appropriateness to leach salts. New technologies of surface irrigation -modernized furrowed and flat basin systems, land levelling and improved water use managementtogether with the cropping pattern adjustment, offer feasible solutions for irrigation modernization well adapt to local conditions [2,3]. To control soil salinization, that is a common and serious problem, farmers usually over irrigate as a guarantee to leach soil salts and having a good soil water refill.…”

“…A set of infiltration data concerning families of infiltration curves and seasonal irrigation events is then required [9]. Thus, the objectives of this study were to characterize infiltration and advance and recession of water within the basins, as well as to determine main performance indicators aiming at further application of improved design [10,11] focusing water saving and higher farmers' incomes.…”
