    For a long while now, there has been talk of a drought in Germany; now, many regions have been deluged with water. How do authorities prepare for these two extremes?

    The Colorado River follows a 1,450-mile route generally southwest from north central Colorado to just east of Las Vegas. From there it turns south to form Arizona’s western border with Nevada and California, and then the border between Mexican states Sonora and Baja California before emptying into the Gulf of California. Between the U.S. and Mexico, 40 million people depend on water from the Colorado.As the climate continues to warm and the amount of water available for humans continues to drop, low flows may become the new normal, he added.

    Fresh water is scarce in many parts of the world and must be obtained at great expense. Communities near the ocean can desalinate sea water for this purpose, but doing so requires a large amount of energy. Further away from the coast, practically often the only remaining option is to condense atmospheric humidity through cooling. Current technologies allow water harvesting only at night, but a new technology, for the first time, allows water harvesting 24 hours around the clock, even under the blazing sun.

    Irrigation technology has developed to the point where pressurized pipes can deliver water for irrigation while generating in-conduit hydropower that can be used to power electric pumps that currently rely on diesel, and in the future, also power electric tractors and combines.

    Long-term water security is essential for the future of Texas, and the state acutely needs a common law system that can balance world-scale agricultural activity, industrial development and urban growth while also protecting private property rights, according to new research.

    While a drought grips the southwestern United States and water supplies dwindle, decision-makers face increasingly difficult decisions about who, or what, gets water. Researchers have developed a model — the Framework for Assessment of Complex Environmental Tradeoffs (FACET) — designed to navigate and rigorously evaluate competing environmental, economic, and social impacts.

    Just about every indicator of drought is flashing red across the western U.S. after a dry winter and warm early spring. The snowpack is at less than half of normal in much of the region. Reservoirs are being drawn down, river levels are dropping and soils are drying out. It’s only May, and states are already considering water use restrictions to make the supply last longer.

    A new method to trigger rain where water is scarce is being tested in the UAE, using drones. The drones carry an electric charge that is released into a cloud, giving cloud droplets the jolt they need to clump together and fall as rain.

    Using a new computer framework, scientists are able to project future floodwaters under a changing climate. The approach could help California water managers plan for and redirect floodwaters toward groundwater aquifers, alleviating both flood and drought risks.

    When winter storms threaten to make travel dangerous, people often turn to salt, spreading it liberally over highways, streets and sidewalks to melt snow and ice. A new study warns that introducing salt into the environment — whether it’s for de-icing roads, fertilizing farmland or other purposes — releases toxic chemical cocktails that create a serious and growing global threat to our freshwater supply and to human health.

    Interstate water disputes are as American as apple pie. States often think a neighboring state is using more than its fair share from a river, lake or aquifer that crosses borders. Climate stresses are raising the stakes.

  • ARGUMENT: Water crisis

    In February, much of Texas plunged into darkness when the state’s electricity grid failed due to extreme cold weather conditions. What started as a foreseeable blackout quickly became a life-threatening calamity. “This catastrophe illustrates what happens when aging and inadequate infrastructure is hit by extreme rain or snow—an increasingly regular occurrence due to climate change,” Lucía Falcón Palomar, Obinna Maduka, and JoAnn Kamuf Ward write. “And, the matter extends well beyond Texas. It is easy to forget that, within U.S. borders, communities have long endured the conditions seen in Texas in February.”

    Water’s value to society goes far beyond quenching thirst. An indispensable resource, it is required not only to sustain life, but also for economic prosperity. Water, for example, is needed to generate energy and to manufacture nearly everything, from food to clothes, cars and electronics. Our future economy and national security highly depend on the availability of clean water. But there is a limited supply of renewable fresh water when and where it is needed.

  • Quick Takes // By Ben Frankel

    In 2009, the U.K. intelligence services submitted their annual intelligence report to then-Prime Minister Gordon Brown, warning of the coming threat of “water wars” between states vying for diminishing fresh-water resources. Rising water-related tensions between India and Pakistan and between Ethiopia and its neighbors bear out the report’s warnings. The recent decision by Turkey to use its dam system to limit the amount of water flowing into Syria is a demonstration of using the control over water sources for exerting pressure on neighboring states.

  • Water wars

    Turkey has reduced the volume of water flowing downstream toward Syria, and the first to feel the pinch are the Kurds in Syria’s Kurdish region. In the last decade. Turkey has built twenty-two dams in southeast Anatolia, leading to fears in Syria and Iraq that Turkey was going to use its control over the sources of the Tigris and the Euphrates to apply political pressure on both countries.

    Bioenergy is frequently considered one of the options to reduce greenhouse gases for achieving the Paris climate goals, especially if combined with capturing the CO2 from biomass power plants and storing it underground. To avoid a substantial increase in water scarcity, biomass plantations for energy production need sustainable water management, a new study shows.
