“…There is no doubt about the seriousness of the application of a water pricing policy for the future of irrigated lands, since it will presumably have a negative influence on their competitiveness and the surrounding socio-economic conditions , although in certain cases there are studies that suggest the opposite (Doppler et al, 2002). A complete revision of the water demand policies (including studies and experiences concerning pricing policies and water markets) can be consulted in Sumpsi et al (1998, Chapter 3).…”

Irrigated agriculture has come under close scrutiny in Europe recently because of its high share of total water consumption and its apparent inefficiency. Several water policies have been advocated, in particular the use of economic instruments such as water markets. This paper simulates the impact of a policy based upon water markets on agricultural production in the internal river basins of Catalonia (Spain). This zone presents certain particularities that make it very interesting to study: competition between sectors for the resource (agriculture-urban consumption-recreational uses), recent periods of resource insufficiency and conflicts between irrigators as a result of the measures taken by the hydraulic administration in drought situations. The results show that these markets would guarantee an optimal reassignment of the resource in situations of supply restrictions, and although compared to the situation without markets they would not mean higher economic profits for the irrigators, they could prevent conflicts between them. Nevertheless, doubts exist about their acceptance by irrigators.Additional key words: irrigated agriculture, multicriteria decision models. Resumen Evaluación de mercados de aguas de riego en las cuencas internas de Cataluña (España)Últimamente se ha puesto en duda el papel económico del regadío en Europa, debido al elevado consumo de agua que representa, así como a su aparente baja eficiencia de uso. Al mismo tiempo, las políticas tradicionales de gestión de aguas están en entredicho, surgiendo nuevos planteamientos, destacando entre ellos el uso de instrumentos económicos como los mercados de aguas. Este artículo analiza el impacto sobre la producción agrícola de la instauración de mercados de aguas en un área de riego comunitario ubicada en las cuencas internas de Cataluña (España). Esta zona presenta ciertas particularidades que hacen que su estudio sea especialmente interesante: se trata de un área con una elevada competencia intersectorial por el uso del recurso (agricultura-consumo urbano-usos recreativos), recientes periodos de insuficiencia en el suministro y conflictos entre regantes como resultado de las medidas tomadas por la administración hidráulica en caso de sequía. Los resultados obtenidos muestran que los mercados garantizan una reasignación óptima del recurso en situaciones de restricción del suministro, y aunque globalmente no generan una ganancia económica muy elevada respecto a la situación sin mercado, sí podrían evitar conflictos entre regantes. Sin embargo, existen dudas sobre su aceptación práctica por parte de dichos regantes.Palabras clave adicionales: agricultura de regadío, modelos de decisión multicriterio.

“…In theory, irrigation water use can be reduced by increasing the price of irrigation water [3,[69][70][71], introducing improved irrigation systems [6,[72][73][74], and training farmers in irrigation practices [29,69]. Furthermore, reinforcing private ownership of wells may be an option, since well owners have been shown to use irrigation water and groundwater resources in a more sustainable way than well leasers [69].…”

Jordan faces great internal water scarcity and pollution, conflict over trans-boundary waters, and strong dependency on external water resources through trade. This paper analyzes these issues and subsequently reviews options to reduce the risk of extreme water scarcity and dependency. Based on estimates of water footprint, water availability, and virtual water trade, we find that groundwater consumption is nearly double the groundwater availability, water pollution aggravates blue water scarcity, and Jordan's external virtual water import dependency is 86%. The review of response options yields 10 ingredients for a strategy for Jordan to mitigate the risks of extreme water scarcity and dependency. With respect to these ingredients, Jordan's current water policy requires a strong redirection towards water demand management. Actual implementation of the plans in the national water strategy (against existing oppositions) would be a first step. However, more attention should be paid to reducing water demand by changing the consumption pattern of Jordanian consumers. Moreover, unsustainable exploitation of the fossil Disi aquifer should soon be halted and planned desalination projects require careful consideration regarding the sustainability of their energy supply.

ABSTRACT:The water scarcity crises in the world and specifically in Iran, requires the proper management of this valuable resource. According to the official reports, around 90 percent of the water in Iran is used for agriculture. Therefore, the adequate management and usage of water in this section can help significantly to overcome the above crises. The most important aspect of agricultural water management is related to the irrigation planning, which is basically an allocation problem. The proper allocation of water to the farms is not a simple and trivial problem, because of the limited amount of available water, the effect of different parameters, nonlinear characteristics of the objective function, and the wideness of the solution space. Usually To solve such complex problems, a meta-heuristic method such as genetic algorithm could be a good candidate. In this paper, Genetic Algorithm (GA) is used for the allocation of different amount of water to a number of farms. In this model, the amount of water transferable using canals of level one, in one period of irrigation is specified. In addition, the amount of water required by each farm is calculated using crop type, stage of crop development, and other parameters. Using these, the water production function of each farm is determined. Then, using the water production function, farm areas, and the revenue and cost of each crop type, the objective function is calculated. This objective function is used by GA for the allocation of water to the farms. The objective function is defined such that the economical profit extracted from all farms is maximized. Moreover, the limitation related to the amount of available water is considered as a constraint. In general, the total amount of allocated water should be less than the finally available water (the water transferred trough the level one canals). Because of the intensive scarcity of water, the deficit irrigation method are considered. In this method, the planning is on the basis of the optimum and limited allocation of water, and not on the basis of the each crop water requirement. According to the available literature, in the condition of water scarcity, the implementation of deficit irrigation strategy results in higher economical income. The main difference of this research with others is the allocation of water to the farms. Whilst, most of similar researches concentrate on the allocation of water to different water consumption sections (such as agriculture, industry etc.), networks and crops. Using the GA for the optimization of the water allocation, proper solutions were generated that maximize the total economical income in the entire study area. In addition, although the search space was considerably wide, the results of the implementation showed an adequate convergence speed. The repeatability test of the algorithm also proved that the algorithm is reasonably stable. In general the usage of GA algorithm can be considered as an efficient and trustable method for such irrigation planning problems. By optim...
