when resources like water are at a premium. For instance many farmers are now using methods like flow-through irrigation drip irrigation micro-sprinklers and more efficient use of groundwater to increase yields.
While the days of farmers using the divining rod to find water are passed long since many farmers especially in developing countries still rely too much on guesswork in making planting irrigation and harvesting decisions.
#Water Woes: Vast US Aquifer Is Being tapped Out Nearly 70 percent of the groundwater stored in parts of the United states'High Plains Aquifer a vast underground reservoir that stretches through eight states from South dakota to Texas
unless current water use is reduced a new study finds. Researchers from Kansas State university in Manhattan Kan. conducted a four-year study of a portion of the High Plains Aquifer called the Ogallala Aquifer
However there are lots of questions about how long the water will last how long the aquifer will take to refill and
10 Health Status Signs Taking water measurements Steward and his colleagues collected data on past and present groundwater levels in the Ogallala Aquifer and developed statistical models to project various
scenarios of water depletion over the next 100 years. Using current trends in water usage as a guide the researchers estimate that 3 percent of the aquifer's water was used up by 1960;
30 percent of the aquifer's water was drained by 2010; and a whopping 69 percent of the reservoir will likely be tapped by 2060.
It would take an average of 500 to 1300 years to completely refill the High Plains Aquifer Steward added.
But if reducing water use becomes an immediate priority it may be possible to make use of the aquifer's resources
if we're able to save water today it will result in a substantial increase in the number of years that we will have irrigated agriculture in Kansas Steward said.
A lot of variables Yet making projections about water security is challenging because there are a number of factors to consider
and leader of the Sustainable Water Resources Program at the University of Texas at Austin who was not involved with the new study.
Asking them to drastically reduce water might be like asking me to retire now because there are so many unemployed people.
Water use efficiencies have increased by about 2 percent a year in Kansas which means that every year we're growing about 2 percent more crop for each unit of water Steward said.
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.

The technology is based on hydrogel film a superabsorbent polymer that can hold 1000 times its weight in water.
He is also the chairman of the advisory board of Agricel a Dubai-based venture that hopes to expand this technology across the United arab emirates. Water scarcity one of the main obstacles Dubai faces was one of the main reasons for launching Agricel in that region.
Hydrogel film reduces the water required for farming by 90 percent and the fertilizer needed by 80 percent while increasing farm productivity by 50 percent overall according to Professor Mori.
Hydrogel can be mixed into the local sandy soil boosting water retention and nutrient distribution. Plants grown in the hydrogel membrane spread their roots throughout the top of the film.
The hydrogel membrane absorbs water and nutrients from a culture medium underneath it delivering water and nutrients to the plants on top
which absorb it from the hydrogel. This method produces healthy and highly nutritious vegetables because the membrane keeps the plants separated from any pathogens in the culture medium allowing only the water
and nutrients to pass through. And because there's no soil there's a lot less need to spray for pests.
For countries like the UAE which imports 90 percent of its food this technology could be crucial for fighting food scarcity and conserving water.

I am supporting water conservation programs. My administration has awarded 92 grants to water conservation projects that will save enough water for an estimated 950,000 people.
We are also working collaboratively with communities around the country on how to best manage freshwater resources in a changing climate,
in order to ensure adequate water supplies and protect water quality. Having clean water isn t enough if people don t have access to it,
which is why we are also working to improve access to clean water for rural American s and border counties.
Already my administration has invested in 5, 100 water and waste water community infrastructure projects to safeguard the health of 18 million rural residents and support 135,000 jobs.
This past summer, we also streamlined the process to improve water quality along the US-Mexico border that previously didn t have the right water facilities to ensure clean water.
By working together, we can continue to build on these achievements and find more efficient ways to use the water available,
conserve where we can, protect jobs, and secure safe drinking water for all Americans today and for years to come.
I will modernize the federal laws and regulations governing water use to enable smarter, more collaborative, more flexible,
and more cost-effective approaches that welcome state and local participation as partners and leaders.
and cooperative conservation measures will improve the water quality of our lakes, rivers, streams and coastal environments.
And some are starting to test the regulation-free waters. Scotts Miracle-Gro, for its part, has said that its bluegrass was meant not to be commercialized,
and can leach into water supplies, leading to health problems. Soil scientists have wanted long to assist poor farmers with their selection
and contaminate groundwater, suffocating aquatic life. To avoid similar problems on African farms, scientists working with local farmers are exploring crop modelling and nutrient management.
But if the homesteaders find water somewhere in the depths of the moon too I feel water found on the moon would be worth like gold

I have heard in other science articles of water being trapped in the minerals of the moon.
if the conditions pressure and maybe having some depth in the ground of the moon there could be a underground lake of sorts trapped pool of water.
So taking all this into consideration perhaps in the depth of the moon deep down in its mineral stricter is contained a pool of trapped water protected from the vacuum of the space.
This pool trapped water being also in the depths of the moon is fluid in nature
and also because of the depth pressure and gravity of the moon it is warm water.
If there existed a pool of water in the depths of the moon it also possible it may contain life in it.

After Hurricane Sandy shoved water into Con Edison's 14th street substation in October causing electricity to arc between capacitors about a quarter million customers were left in the dark.
The city lost power because via water breakers tripped. The breakers tripped for good reasons. If you trip breakers prior to making the situation safe from water you have electrified a lot of fried circuits

That means the steam forms immediately even before the water boils. Halas Rice's Stanley C. Moore Professor in Electrical and Computer Engineering professor of physics professor of chemistry and professor of biomedical engineering is one of the world's most-cited chemists.
When submerged in water and exposed to sunlight the particles heat up so quickly they instantly vaporize water

and maintain a simple centuries-old nonelectric water pump to grow more vegetables? Two Johns Hopkins student teams are working hard to move these green ideas off the drawing board and into the real world.
Their goal is to deploy algae at wastewater treatment facilities to feed on hard-to-remove pollutants such as nitrogen and phosphorus
Wastewater can contain pathogens and dangerous metals like mercury chromium and arsenic said Pavlo Bohutskyi an environmental engineering doctoral student and leader of this team.
At the same time the pathogens in wastewater such as viruses fungi and bacteria could destroy the algae themselves

Their faculty advisers are Edward Bouwer professor and chair of the Department of Geography and Environmental Engineering and Michael Betenbaugh professor in the Department of Chemical and Biomolecular engineering.
In these areas women and children often spend hours each day hauling heavy containers of water from the local stream for drinking and to water crop-growing sites up to a half-mile away.
Instead they use the kinetic energy of flowing stream water to power the lifting of a fraction of this water to a higher elevation.
The process eliminates hand-carrying water and provides much needed irrigation water for the cultivation of winter vegetables.

Unlike gas-powered engines that spew out pollutants the only byproduct of hydrogen fuel is water.
of which could grow at around the boiling point of water. The researchers chose to use xylose
and reproduce instead of splitting water molecules to yield pure hydrogen. To liberate the hydrogen Virginia Tech scientists separated a number of enzymes from their native microorganisms to create a customized enzyme cocktail that does not occur in nature.
The energy stored in xylose splits water molecules yielding high-purity hydrogen that can be utilized directly by proton-exchange membrane fuel cells.
Each of these plants makes electricity by boiling water to create steam to run electric turbines.
Just as importantly by fabricating them on cellulose nanocrystal (CNC) substrates the solar cells can be recycled quickly in water at the end of their lifecycle.
