Hierarchy Process

Improving agricultural water use efficiency (WUE) and reducing the proportion of agricultural water consumption are of great significance for coping with the water crisis in the world, particularly in northwest China. However, considering the lack of WUE indicators for the selection and an evaluation of system construction in Xinjiang, the implementation of the strictest water resources management system in this province has been seriously restricted. In order to evaluate the agricultural water utilization situation of 14 administrative regions in Xinjiang, a synthetical evaluation model is proposed combining the analytic hierarchy process method and the fuzzy evaluation method. Firstly, an evaluation system composed of the target layer (i.e., water use efficiency), the criterion layer (i.e., water use situation, engineering measure, planting structure) and the index layer (e.g., utilization coefficient of irrigation water, weighting irrigation quota, grain production per cubic meter of irrigation water, etc.) is constructed. Secondly, a classification standard of evaluation indicators is put forward and a fuzzy evaluation model is introduced into calculate agricultural WUE. Finally, key evaluation indicators that lead to these administrative regions with very low WUE are identified, and discussions on improving agricultural WUE in Kashgar are made. The evaluation results of this study are beneficial for providing support for reforming agricultural water use and promoting sustainable agricultural development in Xinjiang.

Irrigation coefficient is not only a critical criterion of the efficiency of agricultural water use, but also an important basis for the evaluation of regional water-saving scheme. According to the Head-tail method (measured net irrigation water use and gross irrigation water use), the irrigation coefficient of Hongguang irrigation district was determined in this paper. The results showed that this method well fitted the real situation of Hongguang irrigation district, and had several advantages including conceptually clear, convenient to use by local staffs. Practical application of this method in irrigation district provides good reference for the future routine evaluation of irrigation efficiency in irrigation.

Irrigation water use efficiency is an important index to evaluate agricultural water use efficiency of irrigation districts, and is a basic parameter of hydraulic engineering construction and water management. However, there are many problems in practical applications of the traditional irrigation water use efficiency which is based on sufficient irrigation theory. This paper puts forward a new concept and determination method of irrigation water use efficiency based on the theories of deficit irrigation. Finally, we discussed the connotations from the project characteristics, benefit characteristics, spatial scale and time scale characteristics.

Abstract The irrigation water price is an indispensable element for the modernization of agriculture and the realization of rural revitalization. As a pilot initiative for agricultural water price reform, Hebei Province has explored various effective patterns. This study analyzed 714 first-hand data points obtained from agricultural irrigation areas in Hebei Province. The ‘two lines and three grades’ water price policy is difficult to implement in practice. The ‘overuse-charge’ includes two levels of water use standards, the water price and reward standards in each level are inconsistent, especially, actual irrigation water use far more than Individual Allowable Water Volume (IAWV). Similarly, there is a negative relationship between irrigation water use and water fees at the critical point of IAWV, that is, the more water used, the less water fees paid. The ‘one line and two grades’ water price policy is proposed. The water volume less than the irrigation quota should be purchased by the government or rewarded farmers, on the contrary, the water price should be increased. It is suggested to improve the installation of irrigation metering facilities, popularization of field water-saving technology and quota management in the groundwater water irrigation region.
