Available fresh water resources are subjected to an ever-increasing pressure due to extensive agricultural water demand for irrigated lands. A long-term perspective in shortage of fresh water resources, especially in arid and semi-arid area, highlights an urgent solution for innovative irrigation strategy and agricultural water management. This paper is a review on the wide applications of the ...

Water resources and land use are closely linked with each other and with regional climate, assembling a very complex system. The understanding of the interconnecting relations involved in this system is an essential step for elaborating public policies that can effectively lead to the sustainable use of water resources. In this study, an integrated modelling framework was assembled in order to ...

Water is vital to food production: every calorie of plant food requires at least one litre of water, while one calorie of meat or dairy product can require up to 10 litres of water. Water is supplied either through rainfall or through irrigation. Irrigated agriculture uses 18 per cent of agricultural land, and produces 40 per cent of agricultural products. But urbanisation, agricultural land de...

khorasan razavi province with the total precipitations of less than 225 mm/year and total area of irrigated area of 1087466 hectare is considered as one of the most important agricultural region in iran. this province has also important role in local and national economy. lack of perennial river and little amount of surface water has caused 1.06 billion cubic meter of over withdrawn from ground...

[1] Global food security increasingly relies on the trade of food commodities. Freshwater resources are essential to agricultural production and are thus embodied in the trade of food commodities, referred to as ‘‘virtual water trade.’’ Agricultural production predominantly relies on rainwater (i.e., ‘‘green water’’), though irrigation (i.e., ‘‘blue water’’) does play an important role. These d...

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...

Bioremediation is the use of living organisms, primarily microorganisms, to degrade environmental contaminants into less toxic forms. Nine biobeds (ground cavity filled with a mixture of composted organic matter, topsoil, and a surface grass) were established at Kentucky State University research farm (Franklin County, KY) to study the impact of this practice on reducing surface runoff water co...
