What 11 Billion People Mean for Water Scarcity From lawns to flood irrigation here are five ways that people waste water

Irrigation Agriculture uses about 70 percent of the available freshwater on the planet. Around the world most farming relies on flood irrigation where fields are drenched with water and the excess runs off into nearby streams and rivers.

But flood irrigation wastes tons of water and can pollute waterways with fertilizers creating dead zones in the ocean (where oxygen is used up

and not available for marine creatures) and contributing to algal blooms which can be toxic to marine life.

Some regions such as Israel have moved to highly efficient drip irrigation which directs water right onto the roots of the plant.

which provides the most agriculturally important irrigation in the state of Kansas and is a key source of drinking water for the region.

If current irrigation trends continue unabated 69 percent of the available groundwater will be drained in the next five decades the researchers said in a study published online today (Aug 26) in the journal Proceedings of the National Academy of Sciences.

That's happening because of increased irrigation technology crop genetics and management strategies. But in some areas of the country's plains the properties of the groundwater and soil largely dictate the irrigation techniques Scanlon said.

In parts of Texas and Kansas the groundwater is brinier which means if some farmers employ more efficient irrigation techniques they will also be pumping up salty deposits that are washed not adequately away by rainfall.

This is a very nice study but we really need to address droughts and socioeconomic issues and other approaches to figure out the problem beyond the technical Scanlon said.

#Western Crop Watering May Make Wetter East Coast Summers SAN FRANCISCO Intensive irrigation in the Western United states could be causing wetter summers on the East Coast new research suggests.

Agricultural irrigation can contribute to downstream precipitation said study co-author Travis Andrews a doctoral candidate in earth and environmental sciences at Lehigh University in Pennsylvania.

whether irrigation could play a role as well: Agriculture accounts for 70 percent of all water use on the planet

and many other variables to look at how irrigation affected rainfall patterns. The team found that about half of the water fed to thirsty crops in the Western parts of the country evaporated into the atmosphere where air currents carried it to the Northeast.

On average about 0. 5 inches (1. 2 cm) of rain fell on the Northeast during June and a July as a result of the heavy irrigation the model found.

The impact of irrigation isn't all that surprising given that the western United states poured enough water into crop irrigation to fill the entire Great lakes region with 2. 3 feet (0. 7 meters) of water

All told irrigation could account for about a quarter of the increased sogginess on the East Coast though global warming is likely responsible for the rest he speculated.

We can't stop the irrigation; it's critically important for food security especially in the face of more droughts Andrews said.

Flood irrigation a practice in which farmers drench fields with water from hoses or other sources creates runoff that carries pesticides into local rivers

and use drip irrigation to target water directly to a plant's roots. Conversion to drip irrigation is happening albeit slowly.

In the United states the National Resources Conservation Service offsets some costs of implementing water-sparing irrigation.

However many farmers don't know about these programs and installing drip irrigation requires placing irrigation tape underground which is labor-intensive and costly.

This method may not work with crops in which tilling could frequently cut the underground infrastructure Greenberg said.

although Greenberg said she sees more and more sprinkler systems replacing wasteful flood-irrigation systems. In another solution seawater or treated wastewater could replace freshwater for crops Davies said.

Nature Newschina must rapidly improve its outdated irrigation infrastructure if its ambitious plans to save water are to be realized,

China's irrigation systems reach less than half of the total farmland. In Henan province, for instance,

Most of the irrigation systems in China were built in the 1950s and are maintained poorly. Moreover, most farmers use flood irrigation-where water is allowed to flood an entire field-a millennia-old practice that wastes a great deal of water.

To meet the ambitious water-conservation target China must modernize its irrigation infrastructure and switch to drip irrigation, says Haim Gvirtzman, a hydrologist at Hebrew University in Jerusalem, Israel.

Drip irrigation is by far the most water-efficient method of irrigation, whereby water is delivered at or near the root zone of plants, drop by drop, through an extensive web of tubing.

Switching to drip irrigation would help to save at least half of the water, says Gvirtzman. It's cheaper in the long run, too.

The level of water resources per person in Israel is only 12%of that in China,

he adds. By using water more effectively -and by recycling 70%of its sewage water for agricultural irrigation-Israel gets by with the very limited water at its disposal.

Irrigation reform needed in Asia: Nature Newsinternational experts have called for urgent changes to the way water is used in farming throughout Asia.

the Food and agriculture organization of the united nations and the Asia-Pacific Water Forum warns that Asian countries must modernize their ageing irrigation systems

Most of the irrigation infrastructure was built in the 1960s and 1970s during the Green revolution that allowed Asian agriculture to flourish.

state-funded irrigation systems that powered the Green revolution helped Asian countries to become self-sufficient in food production,

By lowering food prices, they also discouraged further investment in irrigation systems. The report was motivated by the spike in food prices in 2007-08

yet the irrigation systems were designed principally for cereal production. A lot of 1970s irrigation had to do with canals surface irrigation,

says Colin Chartres, director-general of the IWMI. These surface-irrigation systems have fallen into disrepair since the 1990s for a variety of reasons

including poor maintenance by governments. Many were not set up to properly cater to farmer's needs

The main alternative to these old irrigation systems is allowing farmers to tap directly into groundwater themselves known as atomistic irrigation.

The report backs this form of irrigation, as long as it is regulated tightly. The unregulated use of groundwater means that

although surface irrigation has been shrinking in Asia, the total area of irrigated land has been expanding.

This report aims to increase the productivity of irrigation, not by using more water but by making irrigation systems more efficient, says Chartres.

Two recent papers show that groundwater supplies in Asia have been decreasing much faster than was previously thought1, 2. James Famiglietti of the University of California, Irvine,

In the United states for example, irrigation demand is putting tremendous pressure on groundwater both in California's Central Valley and in the Ogallala aquifer in the High Plains in the centre of the country.

The report calls for more education for farmers and others working in the irrigation sector and for investment in programmes to cut the overall need for water such as building better roads

The authors also suggest involving the private sector in managing the irrigation systems to take some of the burden off governments.
