the price of water in agriculture plays an important role in the water allocation management. therefore, the optimum strategies of cropping pattern could be designed when water price analysis are considered in a predetermined economic framework. in the present study, a programming model was developed using the genetic algorithm for optimal water allocation in the eastern north of khuzestan prov...

The scarcity of water resources and supply resources limitation, have caused an increasing gap between water supply and demand specially in recent decades in almost all regions of the globe. One of the best known solutions proposed by the economists is using the different water pricing approaches thereby obtaining the optimal allocation and social justice. To this purpose, this paper uses the p...

The allocation, or re-allocation, of water to achieve environmental sustainability in farming communities can be a source of considerable conflict. “What’s fair” when sharing water between different agents and the environment becomes paramount in people’s decision making. Issues such as self interest; efficient uses of water; business investments; viable communities and prior rights to water al...

When it comes to conflicts over the allocation of freshwater supply, who bears the burden, at what cost, and at what scale are important questions. While science can contribute to resolution of certain water allocation disputes, more scientific certainty will not resolve most water allocation controversies. Water stress in Africa and in theMiddle EastÑparticularly in theNile BasinÑis likely to ...

Irrigated agriculture in Idaho faces a decline in the availability of water and increasing costs for that available water. The demand for recreational and environmental urban water use continues to grow. Adopting improved irrigation technology is one of the few remaining alternatives that agriculture can use to address this problem. Development of large-scale water projects to enhance water sup...

On the basis of the pre-research of index system of province initial water rights allocation system, as well as the complexity and differences of the allocation system, the index system of province initial water rights allocation system in this paper is comprehensively designed first, and the index framework divided into three layers of target, criteria and index angles is established. Taking a...

According to the newly introduced water resources management in China, which is the most stringent thus far, pollution limits of water functional zones should be enhanced. In response to this recent change, we propose a provincial initial water rights incentive allocation model with total pollutant discharge constraint. Firstly, three objective functions are set up, namely the maximum comprehen...

pricing policies play an important role in water demand management and its optimal allocation. determining proper water price leads to optimal allocation of water especially in agricultural consumptions. applying new subsidy targeting law in iran which insists on pricing water based on its supply cost, will effects considerably on water resource management in agriculture sector. so, in this stu...
