The relationship between per capita municipal water use (PCMWU) and gross domestic product (PCGDP) (purchasing power parity, constant 2011 US$) is statistically analysed for each country in the world. results indicate that PCMWU will increase with rising PCGDP at beginning, which then decrease when reaches a certain level. This trend follows rules of Water Use Kuznets Curve, an inverted U-shape...
The issue of land use and land-use intensity has long been linked to water quality globally. Changing in New Zealand, especially pastoral systems, over the last 50 years have caused nit...
Eucalyptus plantations occupy almost 20 million ha worldwide and exceed 3.7 million ha in Brazil alone. Improved genetics and silviculture have led to as much as a three-fold increase in productivity in Eucalyptus plantations in Brazil and the large land area occupied by these highly productive ecosystems raises concern over their effect on local water supplies. As part of the Brazil Potential ...
soilless culture of greenhouse vegetables has been a fast developing section in iran during recent years. most growers fertigate plants without enough knowledge about plant water requirements. since some soilless substrates have low water retention capacity, wasting a great amount of nutrient solution can be occurred due to poor management. in this research work, effects of hydro gel amendment ...
due to limitation of conventional water resources, the use of unconventional water for agriculture is unavoidable. therefore, in order to investigate the effect of using different amounts of municipal wastewater on yield, yield components and water use efficiency of cotton in drip irrigation systems, a field experiment was carried out during 2010 and 2011 growing season at experimental farm of ...
The relative impacts of different types of land use on the surface water quality are yet to be ascertained and quantified. In this paper, the influence of different types of land use on surface water quality is investigated. Rain events samples from different land use in the central plateau, Iran, were analyzed for major ions. Statistical analyses were employed to examine the statistical relati...
Water available for irrigation is declining in many rice-growing regions around the world. Global populations continue to rise increasing crop production demand. Rice production systems must face the dilemma of maintaining or increasing yields with less water available to irrigate. Alternate wetting and drying (AWD) has shown to be an effective tool for water conservation in irrigated rice syst...
