Agricultural water productivity (AWP), which is associated with multiple factors, is an important index for measuring the effectiveness of agricultural water management. The purpose of this study is to promote AWP through optimally allocating limited agricultural water resources with the coordination of related elements. Firstly, the coordination effects of multiple factors related to AWP are quantified as relative optimum membership degrees based on the fuzzy optimum selecting theory. Secondly, based on the relative optimum membership degrees for various crops, a linear fractional programming model is established to maximize AWP in agricultural water resources allocation. Thirdly, the impacts of the allocation schemes on the development of social-economy and ecological environment are discussed using the multi-dimensional regulation theory. The developed integrated system has advantages in increasing agricultural water productivity through the coordination of multiple factors with aspects of economy, society and resources. Moreover, the system is capable of screening schemes considering harmonious development of resources, economy, society and ecology based on optimization results, providing decision makers with more sustainable schemes for irrigation water allocation. The integrated system including the aforementioned three parts is applied to a real-world case study in China to demonstrate its feasibility and applicability. Different water allocation schemes for various crops under different scenarios were obtained. The average value of AWP is 1.85 kg/m3, which is 0.31 kg/m3 higher than the current value of AWP. An optimum scheme with 1.1405 × 108 m3 of water being allocated was also selected due to its highest level of coordination for resources, economy, society and ecology. The developed system can provide an effective method for AWP promotion. The obtained results can help local decision makers adjust water resources allocation schemes.

Water allocation is an essential programming to support the sustainable development of Wuwei Basin, Gansu Province, China. To satisfy the demands of the decision makers (DMs) of each subarea and the total area, a bilevel multiobjective linear programming (BLMOLP) model is proposed. In the BLMOLP, DMs have a hierarchy of two levels—the upper level and the lower level DMs. In this paper, a fuzzy goal programming (FGP) approach is applied to solve the BLMOLP. Firstly, the upper level is solved and used as the tolerance for the lower level. Then the weights of each objective function in the lower level are evaluated. Finally, a satisfied optimization solution of the problem was calculated. The result suggests that the FGP is a simple and feasible approach to BLMOLP problems. The proposed method was applied to a case study for water resources allocation in Wuwei Basin. For four scenarios under consideration, the model can effectively balance the benefits among all regions and sections according to the priority of the upper level decision makers. The results indicate that comprehensive solutions have been obtained.

The fact that the water resource governor has to allocate limited water resources to two competing agricultural water users under the administrative system (AS) leads to a principal-agent issue. Hence, this paper constructs a two-stage performance-based allocation mechanism to motivate two competing water users (referred to as the agents) to act in accordance with the interests of the governor (referred to as the principal). This mechanism is about the interaction between the governor and two water users. The governor aims to improve water resources allocation efficiency and balance economic and environmental development, while each agricultural user focuses on the overall amount of water resources they have to operate and would like to ignore environment protection issues. Besides, the total water resources invested into production or environment is two water users’ private information, which is unknown to the governor. In the first stage, the governor allocates water resources between two users according to their previous performances, including production and environmental aspects. Results indicate that the equilibrium state of this mechanism could encourage two water users to focus on production and environment performances simultaneously and to help the governor transfer the pollution cost to two water users under the external of pollution cost, which motivates them to compete for available water resources. This competition between two users will directly affect users’ behaviors. These results could improve water resources allocation efficiency significantly and realize the sustainability of water resources in the agricultural field under the current AS. This perspective could also provide a new insight for the management of agricultural water resources allocation and offer relative decision support to relative governors.

Abstract To choose the best policy of the water resources allocation, considering both the quantitative and qualitative factors based on the possible uncertainties, there has always been a significant problem in the dry lands from perspectives of the decision makers. In this paper, using Game Theory concept, a novel hybrid approach of the Game Theory based fuzzy logic is proposed to reconcile conflicts among stakeholders of dam reservoirs who have their own different strategies and utilities to choose the best policy in order to gain the highest profit regarding the situations they deal with. In the proposed method, after the fuzzification of decision makers’ strategies, a matrix called a “priority matrix” is formed in which a combination of their strategies and priorities is presented as the matrix elements. Based on the concept of Nash equilibrium, an optimized scenario is elected from among the bargaining scenarios constructed via the integrated strategies. This method has the privilege of providing a game space in which a large variety of strategies and priorities of many decision makers can be modeled in a fuzzy space of variables to reach a point of agreement. In this study, the 15-Khordad Dam of Iran is selected as a case study area which faces problems such as salinity, low quality water, and conflicts among stakeholders. The results of the study indicated that the proposed method could be led to an optimized strategy for the water resources allocation.

This paper deals with a fuzzy programming approach for treating an interactive two-stage stochastic rough-interval water resource management. The approach has been developed by incorporating an interactive fuzzy resolution method within a rough two-stage stochastic programming framework. The approach can not only tackle dual rough intervals presented as an inexact boundary intervals that exist in the objective function and the left- and right-hand sides of the constraints that are associated with different levels of economic penalties when the promised policy targets are violated. The results indicate that a set of solutions under different feasibility degrees has been generated for planning the water resources allocation. They can help the decision makers to conduct in depth analysis of tradeoffs between economic efficiency and constraint-violation risk, as well as enable them to identify, in an interactive way, a desired compromise between satisfaction degree of the goal and feasibility of the constraints. A management example in terms of rough-intervals water resources allocation has been treated for the sake of applicability of the proposed approach.

Water Allocation Model

Competitions and disputes between various human water sectors and environmental flow of the river are exacerbated due to the rapid growth of the economy in Yellow River basin as well as the limited supply of available water resources in recent decades. It is necessary to implement rational and effective management and allocation to alleviate the pressure of water shortage. In order to promote economic development and maintain the ecological balance of the river, both the water allocation to the river environmental system and different human needs should be of concern when making the allocation polices. This study developed a water allocation model based on Nash–Harsanyi bargaining game theory for optimal water resources allocation among agricultural, industrial, domestic, public, and urban ecological water (watering for urban green space) sectors while ensuring the environmental flow requirements of lower reaches. A comprehensive economic evaluation framework is built to assess the economic benefits of different water uses that were taken as the basis of water allocation model. The annual environmental base flow is 7.50 billion m3 in the lower reaches of Yellow River. Moreover, the optimal annual allocations for agricultural, industrial, domestic, public, and urban ecological water use sectors are estimated as 33.7, 6.42, 3.96, 1.75 and 2.68 billion m3, respectively.

Sumber daya air memiliki peran yang besar bagi sektor pertanian. Air sebagai renewable resources digunakan untuk memenuhi produksi pertanian. Peningkatan produktivitas air pertanian memiliki peran yang penting dalam menghadapi kelangkaan dan kopetisi penggunaan sumber daya air, pencegahan terhadap kerusakan lingkungan dan ketahanan pangan. Tulisan ini bertujuan untuk melihat bagaimana kuantitas dan produktivitas sumber daya air pertanian di Indonesia secara umum. Berdasarkan data luas pertanian Indonesia tahun 2009-2013, luas sawah irigasi di Indonesia mencapai 4,81 juta Ha setara dengan laju peningkatan 9%. Apabila sawah irigasi ini dibandingkan dengan luas baku irigasi sebesar 12.335.832 Ha, maka persentase sawah irigasi hanya sekitar 38%, kondisi ini menggambarkan bahwa pemanfaatan air irigasi masih relatif rendah. Dilihat dari hasil data ketersedian air yang ada di 7 pulau-pulau besar yang ada di Indonesia Pulau Jawa mengalami permasalahan paling tinggi  dimana terlihat dari tingginya tingkat kebutuhan air tidak sebanding dengan ketersediaan air yang ada, sehingga akan berdampak kepada ketahanan pangan dan juga kondisi kesejahteraan masyarakat khususnya petani, dengan hal tersebut ada strategi dalam  dalam upaya peningkatan  penyediaan air dan produktivitas air yaitu dengan cara konservasi ekosistem hidrologis daerah aliran sungai (DAS), peningkatan efisiensi pemanfaatan air pertanian, redistribusi aset infrastruktur irigasi dengan mekanisme pendanaan dan insentif yang sesuai serta adanya harmonisasi antar sektor dan wilayahsetempat dalam pengelolaan sumber daya air pertanian.Water resources have a large role for the agricultural sector. Water as renewable resources is used to fulfill agricultural production. Increasing productivity of agricultural water has an important role in dealing with scarcity and competition in the use of water resources, prevention of environmental damage and food security. This paper aims to have a general view of quantity of agricultural water resources in Indonesia. Based on data on Indonesia's agricultural area in the year 2009-2013, irrigated paddy fields in Indonesia reached 4.81 million Ha, equivalent to the rate of 9% increase. If this irrigated rice field is compared to the irrigated raw area of 12,335,832 Ha, then the percentage of irrigated paddy fields is only around 38%, this condition illustrates that the utilization of irrigation water is still relatively low. Judging from the results of water availability data in 7 major islands in Indonesia that Java Island experiences the highest problems, which can be seen from the high level of water demand that is not proportional to the availability of water, so that it will affect food security and the condition of community welfare especially farmers, with this in mind there is an inner strategy in an effort to increase water supply and water productivity, namely by conserving watershed hydrological ecosystems , increasing efficiency of agricultural water utilization, redistributing irrigation infrastructure assets with appropriate funding mechanisms and incentives and harmonizing between sectors and regions in the management of agricultural water resources.
