Rapid economic and population growth has led to increased demand for water from the industrial and domestic sectors and put pressure on resources available for agricultural production. With growing scarcity and increasing inter-sectorial competition for water the need for efficient and sustainable water allocation policies has also become more important. Finding ways to meet this growing demand...

due to the being in the desert bar and ecosystem sensitivity to water , water management in the agricultural sector of the iran is one of the priorities of managers and planners of this section. therefore accurate modeling of the production function, for policies to increase efficiency and reduce the use of inputs, as well as forecasts for the timely supply with low cost, is of utmost importanc...

abstract surface water restriction and supply variation of these resources causes of over extraction of groundwater and unbalance between feed and extraction of groundwater in iran. agricultural sector as the biggest consumer of water resources has the most share of this unsustainability. this paper studies the conjunctive use of surface and groundwater in agronomy production in qazvin basin, o...

Regarding the increase in needs of human societies to agricultural products, increasing water use efficiency can lead to persistent use of limited water resources. Therefore, in this study using Data Envelopment Analysis (DEA), technical, allocative, managerial and economic efficiency and also Optimal level of inputs is surveyed in order to achieve maximum Efficiency in Marvdasht city in 20...

Compared to surface water, groundwater resources are the primary source of water supply in arid and semi-arid regions of Iran, hence the importance of the management of these resources .  In this regard, we assessed the effects of landuse changes on the qualitative and quantitative status of groundwater resources in Eshtehard region, Iran. Through processing and analyzing the satellite images, ...

Efficient water use is the key for sustainable management of water resources. The major reason of non-efficient management of water resources, especially in developing countries, is nonavailability of reliable hydrological information about the actual water used by different agricultural crops with in a large irrigation system or at the basin scale. Therefore, an estimation of spatially distrib...

The rapid development of agricultural modernization in Hubei province has an influence on cultivated land resources variations to a certain degree. This paper used grey relational analysis method,combined with Hubei province cultivated land area decreased data within the year covering 2000 to 2010 and agricultural modernization development index data, then analyzed the influence relationship be...

Iran is among the world’s arid and semi-arid regions and its demand for water has been increased due topopulation growth, urbanization and the development the economic sectors (industrial and agricultural). Inmany of these regions, the lack of planning and the unauthorized use of resources have led to excessiveexploitation and a lower level of groundwater. The usable groundwater for the country...

one of the core elements of water management and increase agricultural productivity is the efficient use of available resources. due to increasing demand for agricultural products, increase the productivity of scarce resources is essential. optimal utilization of these resources, in addition to meet the demand of the community as a major goal, can also increase operating income to be followed. ...
