One potential solution for farmers would be to switch to a subsurface drip irrigation system that could permanently cut farmers' water use by 25 to 50%. This would alleviate some of the need for conservation and free up more state water reserves for urban locations during times of regional drought. ("University of Arizona studies underground irrigation,"2005, U.S. Water News Online)
Arizona farmers are resistant to drip irrigation, however, and prefer so-called flood or rainwater-propelled irrigation, which is used on about 95% of Arizona crops. "Farmers have a hard time justifying drip irrigation because water is relatively cheap and drip systems can cost from $500 to $2,000 per acre to install." ("University of Arizona studies underground irrigation,"2005, U.S. Water News Online) But not only farmers place cost above conservation. Cost is another prohibition for private residents. Many persons have migrated to Arizona because of the region's cheapness, especially retirees. Converting a home to a more environmentally sound energy model can be prohibitively expensive.
Consider the Phoenix 'gray water' proposal, which suggested installing two sets of pipes in new homes in northeast Phoenix so residents could reuse some of their wastewater as so-called gray water, or water that was below minimum drinking safety requirements that would normally be passed into the sewage system. "In addition to the standard pipes that send wastewater (or black water) to the sewer, a second set would direct cleaner water (gray water) from the washing machine or the shower onto the landscaping. It would save water by reusing it and cut back on water bills for outside irrigation." ("Phoenix snubs idea of wastewater reuse," 2005, U.S. Water News Online) Most residents felt that the $200 tax credits to homebuilders who added the piping for gray-water use, was simply not enough to defray the added cost of installing the new system in comparison to a more traditional system.
Commercial and residential zones, rural and urban...
(Norton, 2003) Individual awareness and conservation projects continue, and Arizona water management entities have made laudable efforts, in addition to the efforts of cities to ensure their water storage and delivery systems are modernized, lining canals and automating pumping and canal controls to help conserve substantial amounts of water. (Norton, 2003) But more efforts are necessary to give residents and communities financial insensitive to defray the costs of conservation.
Some ideas might be to offer tax rebates to consumers to convert to gray water system, and added reserve credits to communities such as Las Vegas that make real efforts to enact strict conservation measures during times of drought, rather than half-hearted measures. To supplement farmers in rural area's water needs, the federal government might be sought to provide added assistance to farmers that make use of innovative drip methods, to enable them to stay financially afloat against competing farmers who make use of the water-wasteful but cheaper flooding methods -- or to place an added tax burden upon farmers who waste water, given that such a substantial portion of the state's water needs is directed towards agricultural use.

Water Pollution Water is an important natural resource upon which all the living beings rely for their existence and growth. Nature has blessed the earth with uncountable water resources but usable quantity is limited. Hence, it is important to use water sparingly. The irony is, human activities result is high water pollution which further shortens the water supply for use. "In an age when man has forgotten his origins and is blind
Water Pollution The vast majority -- over 70% -- of our earth is covered by water. Unfortunately for our thirst, 97.5% of all the water on the planet is salt water. Only 2.5% of the water on planet earth is fresh drinking water. Given that there is such a small percentage of drinkable water on the planet, the resource has become a scarce commodity. Making matters worse is the fact that
Given water scarcity, the high costs of desalinisation and other unconventional methods of supplying water, and the pollution of surface and ground waters, Israel sought other natural supplies of water from the Litani" (Dolatyar, 2002). The Israeli then invaded Lebanon, but were met with extreme resistance. 1990 - Present - Period of return to bargaining tactic The fall of the Soviet Union, the Gulf War (1990-1991) and the interference of the
In the year following that incident, China's State Environmental Protection Agency (SEPA) announced a five-year plan to address the widespread water pollution issues, committing a budget of 125 billion dollars to that national effort (Pacific Environment, 2006). In 2006 alone, the SEPA responded to 161 emergency environmental pollution incidents, almost two-thirds of which pertained to water pollution (China Daily, 2008).

Although the Murray-Darling River covers only about 14% of Australia's irrigated land, 50% of Australia's sheep and 25% of Australia's cattle rely on this source. Also, 40% of the nation's rice crop and 80% of its canned fruit product relies on the Murray-Darling River Complex. In all, three-quarters of Australia's water comes from the Murray-Darling River (Hussainy, p. 205). Of course there are conflicts when so much is at stake.
The trouble is not only in the city of Tianjin but wastewater pollution in China is also found in the east central part of China which is three hundred miles west of Shanghai, lies the Chao Lake and is one of China's five largest freshwater lakes. The major resource of drinkable water supply comes from the Chao Lake. It is also used for an economic as well as an
