IIASA China’s richest provinces have an outsized environmental impact on the country’s water-scarce regions, according to new research from the International Institute for Applied Systems Analysis (IIASA) and the University of Maryland. Many developed regions in China are not only drawing from their own water resources but also contributing to water depletion in other water-scarce regions of the country through imports of food and other water-intensive goods, according to the new...

You may have guzzled a half-liter bottle of water at lunchtime, but your food and clothes drank a lot more. The same half-liter that quenched your thirst also produces only about one square-inch of bread or one square-inch of cotton cloth. Agriculture is in fact one of the world's most insatiable consumers of water. And yet it's facing growing competition for water from cities, industry, and recreation at a time when demand for food is rising, and water is expected to become increasingly...

It's not easy, or economically feasible, to ship freshwater across the globe. But when scientists use food as a proxy for that water - taking into account how much crops are irrigated and livestock are fed - they can get a glimpse of the flow of freshwater between countries. When one research group studied this "virtual water network," they found that the interconnectedness between countries has almost doubled over the last two decades - potentially lending some resiliency to the water trade....

The implementation of virtual water into trading deals has been suggested as a realistic solution to solving the global inequality of renewable freshwater, but new research suggests that it may not be as revolutionary as first thought. In a study published today, Tuesday 7 June, in IOP Publishing's journal Environmental Research Letters, researchers have claimed that virtual water is unlikely to increase water use equality, primarily because the existing amount of virtual water is not large...

Water scarcity in the western U.S. has long been an issue of concern. Now, a team of researchers studying freshwater sustainability in the U.S. have found that the Southeast, with the exception of Florida, does not have enough water capacity to meet its own needs. Twenty-five years ago, environmentalist Marc Reisner published Cadillac Desert: The American West and Its Disappearing Water, which predicted that water resources in the West would be unable to support the growing demand of cities,...

Worldwide Water Consumption Diet Imperative to Earth's Survival ISTANBUL, March 18 /PRNewswire/ -- Water, an element crucial to human existence, is becoming more and more scarce. From the bread we eat to the meat we consume, the global population is contributing to the depletion of the world's water resources, say experts at the 5th World Water Forum taking place in Istanbul, Turkey this week. The Forum is bringing attention to practices of not only corporations, but also individuals that...

By Alister Doyle, Environment Correspondent STOCKHOLM (Reuters) - Labeling foods ranging from spaghetti to meat to show how much water is used in their production could help combat mounting pressure on the world's water supplies, a leading expert said on Tuesday. Typically, a calorie of food demands a liter of water (0.2 Imperial gallons) to produce, according to U.N. estimates. But a kilo (2.2 lbs.) of industrially produced meat needs 10,000 liters while a kilo of grain requires...
