  • WaterWater agencies in Sacramento, Calif. area want state water restrictions rewritten to reflect climate

    Last month, Governor Jerry Brown ordered California’s water agencies to reduce potable urban water use by 25 percent on average over 2013 levels by 28 February 2016. Leaders of Sacramento-area water agencies are now calling for a rewrite of the proposed framework to reflect climate. They argue that the framework is unfair because inland communities require far more water to achieve the same water functions as coastal communities. They also say the region is being punished for its dry heat, while coastal communities are rewarded for their moderate climate.

  • WaterApp checks water for contamination

    Researchers have created a mobile app which can determine just how contaminated a sample of water might be. Using tiny pills containing contaminant-detecting enzymes, users can first determine whether their water is clean or not. If the water is clean, the pills will change the color of the water. If it is contaminated with pesticide, heavy metals, or bacteria such as E. coli, it will remain clear. The app complements the pills by analyzing a series of photos of the water to determine just how contaminated the water is.

  • WaterAquifer Storage and Recovery should be phased in to reverse Everglades decline

    The aquifer storage and recovery (ASR) is a key component in the Central Everglades Restoration Plan (CERP), a joint state-federal effort to reverse the decline of the Everglades ecosystem. CERP aims to “get the water right” by improving the quantity, timing, and distribution of water flows. Over a century of canal drainage and water management has led to extensive losses of natural water storage, leaving the Everglades in critical need of new storage. Although uncertainties about ecological impacts are too great to justify near-term, large-scale implementation of the ASR in the Everglades, the ASR could be phased in to answer several important scientific questions and provide some early restoration benefits, says a report from the National Research Council (NRC).

  • WaterCalifornia drought highlights the state’s economic divide

    As much of Southern California enters into the spring and warmer temperatures, the effects of California’s historic drought begin to manifest themselves in the daily lives of residents, highlighting the economic inequality in the ways people cope. Following Governor Jerry Brown’s (D) unprecedented water rationing regulations,wealthier Californians weigh on which day of the week no longer to water their grass, while those less fortunate are now choosing which days they skip a bath.

  • Water & conflictWater scarcity increase Middle East instability

    At least1.6 billion people worldwide face water scarcity because their countries lack the necessary infrastructure to move water from rivers and aquifers. In the Middle East, this lack of water infrastructure combines with the effects of global warming — including prolonged in droughts — to make the entire region politically and economically unstable. Food supplies are diminished as farmers find it difficult to find water for crops, and even basic sanitary requirements are not met due to poor access to clean water, thus increasing the spread of disease.

  • African securityInternational experts analyze impacts of Ethiopian dam

    By David L. Chandler

    A new report addresses potential effects of huge construction project. According to present plans, the Grand Ethiopian Renaissance Dam (GERD) — now under construction across the Blue Nile River in Ethiopia — will be the largest hydroelectric dam in Africa, and one of the twelve largest in the world. But controversy has surrounded the project ever since it was announced in 2011 — especially concerning its possible effects on Sudan and Egypt, downstream nations that rely heavily on the waters of the Nile for agriculture, industry, and drinking water.

  • WaterChanging human behavior key to tackling California drought: Expert

    California is experiencing a drought that has gone far beyond a “dry spell,” and the state has imposed the first water restriction in state history, aiming to cut back on water consumption by 25 percent. One expert says that strict water conservation measures are long overdue, and that “what is happening is a realization that you can’t simply transplant another ecosystem onto a California desert system or arid southwestern system. In a sense, California and much of the U.S. southwest are living beyond their ecological means. Certain lifestyles have been adopted and crops are being grown that are not endemic or sustainable for this particular bioregion.” He adds: “This is a moment for not just cutting off personal water use and turning the tap off when you’re brushing your teeth, as important as that is. This is a moment of reflection, invitation and, I hope, legislation that will cause people to think about water use in the industrial sector too. This is for the long-term prosperity of the state and sustainability of the ecosystem.”

  • WaterWater shortage grows, and so does the need for technological solutions

    The value of freshwater is becoming more apparent, as more and more areas around the world are suffering from dwindling supply as a result of climate change. The World Bank estimates that water is $1 trillion privatized commodity. Last week, California imposed mandatory restrictions on water use for the first time in its history. California’s unprecedented move is just one example of the political and social issues which will accompany a growing water shortage moving forward.

  • WaterCalifornia not the only state to face water shortage

    Over the past two weeks, California’s long drought — and Governor Jerry Brown’s mandatory water conservation rules — have captured the headlines. As the country keeps an eye on how Californians will adapt to the new reality of water conservation, other states must prepare to maintain the sustainability of their own water supplies. “As far as other states, if they haven’t seen it [water shortages] in the past, it’s something they will see in the future,” says a water policy analyst in Los Angeles.

  • EnergyBig data technology helps identify best river locations for hydro-power generation

    A new technology has the potential to revolutionize the sourcing of renewable energy from rivers. The software app automatically selects appropriate locations in U.K. rivers to site a large range of micro renewable hydro-power turbines in these rivers, and determines the environmental sensitivity of the location.

  • WaterSan Diego to build largest ocean desalination plant in Western Hemisphere

    San Diego County, California will soon become home to a $1 billion desalination plant which would supply drinking water to residents currently having to cut their water consumption by as much as 25 percent in response to the state’s current drought. Small ocean desalination plants already operate throughout the state, but the facility being built in San Diego will be the largest ocean desalination plant in the Western Hemisphere, producing roughly fifty million gallons of drinking water a day.

  • WaterCalifornians mull life with less water

    Following Californian governor Jerry Brown’s decision to enforce mandatory water restrictions for the first time in history, Californians are planning for changes in their daily lives. Experts say, though, that California cannot resemble its drier neighbor, Arizona. “Without water, you can’t live in California,” Stanford University’s Bill Whalen. “It ties into the California psyche. They have plush lawns and nice gardens that require lots of water. They have the ocean and Lake Tahoe skiing. You have a nice car. You want it clean. You need water. You can’t have California agriculture without water. You lose the nation’s salad bowl.”

  • WaterNASA putting satellite eyes on threat to U.S. fresh water

    Algal blooms are a worldwide environmental problem causing human and animal health risks, fish kills, and taste and odor in drinking water. In the United States, the cost of freshwater degraded by harmful algal blooms is estimated at $64 million annually. In August 2014, officials in Toledo, Ohio, banned the use of drinking water supplied to more than 400,000 residents after it was contaminated by an algal bloom in Lake Erie. NASA has joined forces with the U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, and U.S. Geological Survey to transform satellite data designed to probe ocean biology into information that will help protect the American public from harmful freshwater algal blooms.

  • WaterCalifornians hoping the state would innovative itself out of a water crisis

    California’s water agencies have relied on innovation to cope with the worsening drought and depleting water resources. Irrigation systems have evolved overtime to help the agriculture sector maintain crop yields as temperatures rise and wells begin to dry up.Some are hoping the state would innovate itself out of a water crisis.

  • WaterAs the drought worsens, California’s conservation measures fall short

    As the drought worsens, California is doing a poor job of conserving water. Water use has declined by only 2.8 percent in February compared with the same time in 2013. Some Southern Californians are actually increasing their water use. “These are sobering statistics — disheartening statistics, considering how hard we have been working on this,” said Felicia Marcus, chairwoman of California’s water control board, which reported the findings. “We are very concern about these numbers. They highlight the need for further action.”
