in the recent decades, due to water shortage problems, most countries have adopted their new policies from water supply management to water demand management . the main objective of the present study is a simulation of water market in order to determine the role of market in the balance between water supply and water demand and to analysis impacts of irrigation water sharing policies on the cro...

abstract water pricing is a policy instrument for improving water efficiency, reducing water demand, management of the irrigation systems and recovering costs. the underlying principle of water pricing is that it should reflect the opportunity cost of water. in this study, parametric mathematical programming approache were used to estimate the willingness of farmers to pay for groundwater under...

In recent decades, China has been experiencing rapid economic development, population growth and urbanization. These processes have stressed the shortages of water resources in China, especially in the arid regions of northwestern China. In order to sustain the expanding cropland, people increased groundwater exploitation in these regions. The purpose of this study was to quantitatively analyze...

The interdisciplinary nature of water resources problems requires the integration of technical, economic, environmental, social, and legal aspects into a coherent analytical framework. This paper presents the development of a new integrated hydrologicagronomic-economic model in the context of a river basin in which irrigation is the dominant water use and irrigation-induced salinity presents a ...

In the Mesilla Valley of southern New Mexico, furrow irrigation is the primary source of water for growing onions. As the demand for water increases, there will be increasing competition for this limited resource. Water management will become an essential practice used by farmers. Irrigation ef®ciency (IE) is an important factor into improving water management but so is economic return. Therefo...

Both developing and developed countries have problems with availability of water to increase agricultural productivity. The importance of improving water efficiency in agriculture has been the subject in many research papers. The usual approach to limit water consumption in agriculture at the district and farm level is to apply water quotas. These quotas may be either for the whole season or fo...

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...

The aim of this study was to assess the magnitude of evaporation loss from the Agricultural Water Reservoirs (AWRs) for Irrigation at a regional scale and to analyse its impact on water storage efficiency. To this end, we identified the extant AWRs for irrigation in the Segura River Basin (SRB) in southeastern Spain, and calculated the water loss from each AWR per month and year. In order to ac...
