Pipe Dreams: Why Far-Fetched Western Water Projects Won’t Go Away
There are at least half a dozen major Western water pipeline projects under consideration, ranging from ambitious to outlandish.most of these projects stand little chance of becoming reality — they’re ideas from a bygone era, one that has more in common with the world of Chinatown than the parched west of the present.

A Water Strategy for the Parched West: Have Cities Pay Farmers to Install More Efficient Irrigation Systems
Unsustainable water practices, drought and climate change are causing this crisis across the U.S. Southwest. To achieve a meaningful reduction in water use, states need to focus on the region’s biggest water user: agriculture.

Amid Climate Change and Conflict, More Resilient Food Systems a Must: Report
Increased demand for water will be the No. 1 threat to food security in the next 20 years, followed closely by heat waves, droughts, income inequality and political instability.

Generating Power at the Point Where Seawater, River Water Meet
It is theoretically possible to generate electricity through the movement of water in locations where seawater and river water meet. This type of technology is called osmotic power generation or blue energy. Though prototypes of this technology have been built, research is still underway to prove that this technology is scalable and reliable.

Water Resources to Become Less Predictable with Climate Change
Many regions of Earth rely on the accumulation of snow during the winter and subsequent melting in the spring and summer for regulating runoff and streamflow. Water resources will fluctuate increasingly and become more and more difficult to predict in snow-dominated regions across the Northern Hemisphere.

Water Scarcity Drives EU Countries to Restrict Access to Drinking Water
Climate change is making itself felt across the continent, as severe droughts and scarce rain have forced water restrictions in southern European countries. In northern Italy, more than 100 cities and towns have imposed water consumption limits on residents.

Climate Changes Lead to Water Imbalance, Conflict in Tibetan Plateau
Climate change is putting an enormous strain on global water resources, and according to researchers, the Tibetan Plateau is suffering from a water imbalance so extreme that it could lead to an increase in international conflicts.

Critical Global Water Questions
Recent intense heatwaves in India and widespread U.S. droughts have highlighted the need for a global approach to tackling chronic water shortages. The problem is that most governments are not equipped to deal with these challenges of water scarcity, sanitation and climate dynamics.

Sustainable Solution for Oil, Gas Wastewater
As demand for new energy sources grows, the wastewater co-produced alongside oil and gas (produced water) shows no signs of slowing down: The current volume of wastewater - the result of water forced underground to fracture rock and release the deposits - is estimated at 250 million barrels per day, compared to 80 million barrels per day of oil. Engineers are developing a new way to clean the produced water for reuse, and it’s already being tested in Pennsylvania, Texas and North Dakota.

California Hydropower Could Be Cut in Half This Summer: Report
A third year of drought spells less hydropower, more natural gas, and higher electricity prices. The U.S. Energy Information Administration, or EIA, reported last week that as reservoir levels dip far below their historic averages, electricity generation from California’s hydroelectric dams could be cut in half this summer.

Diminishing Snowmelt to Make Colorado, Utah, Wyoming Resemble the Arid Southwest
New research predicts that changes in mountain snowmelt will shift peak stream flows to much earlier in the year for the vast Colorado River Basin, altering reservoir management and irrigation across the entire region. As a result, upper basin in Colorado, Utah, and Wyoming may more closely resemble the arid Southwest.

Does Drought-Prone California Need Another Reservoir?
For a century, California and the West have grappled with the job of storing water. The first half of the 20th century was the heyday of western dams; now many of them are aging; they were designed for the needs and values of another era. Is California “dammed out?” Or could increasing reservoir capacity help the state ride out the new era of aridification?

Western River Compacts Were Innovative in the 1920s but Couldn’t Foresee Today’s Water Challenges
The Western U.S. is in a water crisis, from California to Nebraska. An ongoing drought is predicted to last at least through July 2022. Recent research suggests that these conditions may be better labeled aridification – meaning that warming and drying are long-term trends.
