Decisions on irrigation water management are usually made at different levels, including farms, user associations (WUAs), and regional planning agencies. The latter generally have good access to information decision tools regarding resources management. However, these remain out of reach the final users, namely farmers. study, conducted in irrigated district Cherfech, north Tunisia, had main ob...

Empirical insights were made into the challenges of supplying water to communities within low-income areas peri-urban Blantyre, Malawi. A networked public supply is provided those without a domestic tap via communal kiosks managed by community-based Water User Associations (WUAs) under government mandate. There has been considerable debate surrounding tariff charged for supplied such vulnerable...

in recent years, farming section of south khorasan province faces different limitations such as increasing shortage of water resources and continuous reduction of weather showers.considering consecutive droughts and water crisis in agricultural plain of the province, it is necessary to use water resources optimally and increase productivity of water shortage input. comparison of water productiv...

the main purpose of this study was to analyze the problems of water user associations (wuas) in the irrigation management transfer (imt) process. the study is based upon a descriptive-correlational research method. the statistical population of the study consisted of 2500 farmers in wuas. a sample of 262 farmers was selected using “random sampling” method. data were collected through questionna...

The Cooperative Water Allocation Model (CWAM) is designed within a general mathematical programming framework for modeling equitable and efficient water allocation among competing users at the basin level and applied to a large-scale water allocation problem in the South Saskatchewan River Basin located in southern Alberta, Canada. This comprehensive model consists of two main steps: initial wa...

Multioutlet hydrants as joint network infrastructure remain briefly addressed in the literature. Studies have always been limited to individual treatment of hydraulic components but not a whole element. This study presents main problems field multioutlet within for pressure irrigation networks Mediterranean agriculture. First, with interviews was carried out 30 water users associations (WUAs) b...

In this paper we applied the parallel evolutionary strategy HGSNash to solving the decision making problem for water resource systems with external disagreement of interests. This problem is usually modelled as a non-cooperative strategic game. We define two different sets of water purifying cost functions for the water users and perform a simple experimental analysis. The efficiencies of HGSNa...

Cognitive radio (CR) network is an excellent solution to the spectrum scarcity problem. Cooperative spectrum sensing (CSS) has been widely used to precisely detect of primary user (PU) signals. The trustworthiness of the CSS is vulnerable to spectrum sensing data falsification (SSDF) attack. In an SSDF attack, some malicious users intentionally report wrong sensing results to cheat the fusion c...

China’s water rights transaction is still in the initial stage of development. There no systematic pricing method for transactions between farmers. This paper puts forward a model among farmers water-deficient areas. The price consists cost and earnings price. determined by studying crop production function, calculating crop’s marginal benefit two parties, combining Cooperative Game Theory. Fin...
