  4. -Groundwater in Texas Shrinking (National Geographic)
      "Farmers in the District draw from the Ogallala Aquifer, a vast underground water reserve that supplies portions of eight states and waters 27 percent of the nation’s irrigated cropland. Since much of the aquifer gets little recharge from rainfall today, rising rates of pumping have led to steady depletion. According to the U.S. Geological Survey, a volume of groundwater equivalent to two-thirds of the water held in Lake Erie has been depleted from the Ogallala since 1940."

      "But what the HPWD is attempting, and what is needed in other groundwater-dependent areas threatened by long-term depletion, is sound planning and management. By law, groundwater may be privately owned, but in reality it is a shared resource. Just as many straws in a water glass will empty the glass faster if there’s no limit on the amount allowed per straw, so will an aquifer dry out faster if there’s no limit on the volume pumped per well."

      "The District’s goal is to ensure that at least half as much water remains in the Ogallala in 2060 as it contained in 2010. While such “planned depletion” is still an unsustainable use of water, it slows the depletion down by promoting wiser choices about what crops to grow and how to grow them. And it motivates investments in irrigation efficiency, enabling farmers to get more crop per drop." 07-12

News
  1. Drought Expands in the United States (Time.com)
      "More than three-fifths of the continental U.S. is experiencing at least moderate drought, while 22.3% of the country is experiencing exceptional or extreme drought, the two worst categories according to the bad news bears at the U.S. Drought Monitor. That’s twice the area that was so classified just three weeks ago—a sign of just how rapidly this “flash drought” has deepened—and last week alone, an additional 32 million acres fell into the worst two categories. Like journalists, scientists are running out of ways to say how dry it is."

      "It’ll be particularly tough for livestock producers, who depend on cheap corn for feed, but who can’t depend on the kind of crop insurance that will cushion the blow for many commodity farmers. Though as my colleagues at Moneyland note, the drought will actually bring about a short-term drop in meat prices as ranchers hurry underweight animals to market rather than pay high prices to keep them fed, over the long-term it will mean more for your hamburger or chicken." 08-12

Papers
  1. "The Future Is Drying Up" (New York Times)
      "When I met with [current Secretary of Energy] Chu last summer in Berkeley, the snowpack in the Sierra Nevada, which provides most of the water for Northern California, was at its lowest level in 20 years. Chu noted that even the most optimistic climate models for the second half of this century suggest that 30 to 70 percent of the snowpack will disappear. 'There’s a two-thirds chance there will be a disaster,' Chu said, 'and that’s in the best scenario.' " 10-10

  2. -01 Immense Freshwater Reserves Found Under Ocean Floor (Time.com)
      "Scientists have discovered a massive reserve of freshwater trapped beneath the seabed that could provide water to the world’s coastal cities and mitigate the impact of a looming global water crisis, according to a new study."

      "The study first reported in the journal Nature describes an estimated half-a-million cubic kilometers of low-salinity water buried in undersea aquifers off the coasts of Australia, China, North America and South Africa."

      " 'The volume of this water resource is a hundred times greater than the amount we’ve extracted from the Earth’s sub-surface in the past century since 1900,' the study’s lead author Dr. Vincent Post said, according to Science Daily. 'Knowing about these reserves is great news because this volume of water could sustain some regions for decades.' " 02-14

  3. -01 Massive Reserve of Fresh Water Found Below Oceans (Science.Time.com)
      "Scientists have discovered a massive reserve of freshwater trapped beneath the seabed that could provide water to the world’s coastal cities and mitigate the impact of a looming global water crisis, according to a new study."

      "The undersea reserves have the potential to alleviate the impacts of freshwater scarcity on the planet, Post said, but the resource should be treated with care. Offshore oil and gas exploration or carbon sequestration activities could contaminate the aquifers, which are themselves a limited resource." 12-13

  4. -California Drought Is Becoming a Disaster (CBS News)
      "Many towns and cities already have ordered severe cutbacks in water use."

      "Meanwhile, the Colorado River, which feeds Nevada's Lake Mead, is drying up, meaning the lake is rapidly shrinking. The lake provides water for 20 million people in southern Nevada, southern California and Arizona - and it has lost 4 trillion gallons of water since 2000."

      "Lake Mead is expected to drop at least another 20 feet this year, and that would devastate Las Vegas. Ninety percent of the area's water comes from the lake." 01-14

  5. -California Drought Threatens Water Supplies (New York Times)
      "With no sign of rain, 17 rural communities providing water to 40,000 people are in danger of running out within 60 to 120 days. State officials said that the number was likely to rise in the months ahead after the State Water Project, the main municipal water distribution system, announced on Friday that it did not have enough water to supplement the dwindling supplies of local agencies that provide water to an additional 25 million people. It is first time the project has turned off its spigot in its 54-year history." 02-14

  6. -California Drought: Long-Term Forecasts Are Bleak (Christian Science Monitor)
      "The unseasonal balmy but dry weather is the result of an equally unprecedented high pressure ridge lurking offshore and blocking the typical winter storms needed to drop precipitation all along the West Coast."

      "This ridge has persisted for 13 months and the longer it lingers, the less likely it is to leave, points out climatologist Brian Fuchs, from the National Drought Mitigation Center in Lincoln, Nebraska. "

      "This is just the beginning, says Doug Parker, director of the California Institute for Water Resources. 'We have seen essentially no rain or snowfall this year and short- and long-term forecasts are bleak for California,' says Mr. Parker via e-mail, adding that this means that California will have very low water deliveries to much of its agricultural sector." 01-14

  7. -California Imposes First Mandatory Water Restrictions (New York Times)
      "Gov. Jerry Brown on Wednesday ordered mandatory water use reductions for the first time in California’s history, saying the state’s four-year drought had reached near-crisis proportions after a winter of record-low snowfalls." 04-15

  8. -California May Face a Mega Drought (Liberty Voice)
      "Soon, it may be necessary to truck water to these rural areas so that they will survive, at least for now. California is facing a mega drought whose end will not come tomorrow. If history repeats itself, this mega drought could last at least 180 years." 01-14

  9. -California's Drought Will Influence the Nation (CNN News)
      "Central California's fields and tree crops -- which provide half of the nation's fruits, nuts and vegetables -- are deteriorating. The state holds 80,500 farms and ranches, which together generate more than $100 billion in economic activity, according to the California Department of Food and Agriculture." 01-14

  10. -Corporations Betting on Climate Change (Time.com)
      "In Australia’s climate-stressed bread belt, the Murray-Darling basin, and its analog in the American West, the Colorado River basin, hedge funds have bought up millions of gallons worth of water rights. Other funds, convinced that commodity prices can only keep rising, are part of a new scramble for Africa in which as many as 100,000 square miles of farmland—an area larger than the United Kingdom—have been leased or purchased by foreign investors. Meanwhile, at least two of Manhattan’s most storied investment banks have played farmer in Ukraine, where milder temperatures heighten the appeal of some of the richest soil in the world." 02-14

      "Water scarcity will be one of the defining features of the 21st century. The U.N. predicts that by 2025 two thirds of the world's population will suffer water shortages. Here CNN takes a look at what we do with the water we can drink." 03-12

  14. -Historic California Drought May Be a Warning for the Nation (Christian Science Monitor)
      "The California drought, the worst in its history, could have far-reaching impacts for the state and for a nation that is only now starting to cope with climate change, experts say."

      "Water shortages have widespread impacts. Agriculture and energy generation account for 80 percent of the nation’s clean water use, says David Dzombak, head of Carnegie Mellon University’s Civil and Environmental Engineering Department. And even when cities meet their water demands during a drought, the costs can leave them 'exposed to significant risk of financial failures,' says Patrick Reed, a professor of civil and environmental engineering at Cornell University, in an e-mail." 01-14

  16. -No Drought Relief for California Farms (New York Times)
      "A federal agency said on Friday that it would not release water for most Central Valley farms this year, forcing farmers to continue to scramble for other sources or leave fields unplanted."

      "Water in the snowpack, California’s primary water source, is one-fifth its normal level." 03-15

  17. -Study: Water Shortages Threaten Western U.S. (CNN News)
      "A shrinking snowpack in the Rocky Mountains may make it harder to slake the thirst of a growing population in the Western United States, according to new research from the U.S. government and several universities."

      "The shrinking snowpack serves as a "bank account" for those river systems, which supply drinking water and electric power to more than 70 million people from the Pacific Coast to the upper Great Plains, said Greg Pederson, the study's lead researcher."

      " 'In a nutshell, what you're seeing is synchronous, declining snowpacks across the West since the 1980s.' Based on the new study, the last time that pattern was seen as the mid-1300s to early 1400s, he said." 06-11

  18. -The Global Water Crisis (Christian Science Monitor)
      "The global water crisis – caused by drought, flood, and climate change – is less about supply than it is about recognizing water's true value, using it efficiently, and planning for a different future, say experts."

      "If renewable water supplies – rainfall in lakes, streams, and rivers – are like an annually replenished checking account, then ground water and deep aquifers are the savings. A few thousand years ago, when civilizations first branched out from rivers, they populated areas where they could draw from that savings in the form of ground water 20 to 30 feet below the surface. Globally, this was the norm until the 1950s, when fossil fuel energy became widely available to allow pumping water from ever-deeper depths. Ever since, humanity has increasingly lived beyond the margins of its renewable water supply."

      "In ancient fossil aquifers – in the Great Plains of the United States, the North China Plain, or Saudi Arabia – water levels are not recharged by rainfall. Elsewhere, as in northern India, ground water is used faster than it can be replenished. According to the United Nations, ground-water extraction globally has tripled in the past 50 years, during which time India and China's ground-water use has risen 10-fold." 12-12

  19. -Trees Hurt by the California Drought (Grist.org)
      "The drought may be killing lawns, but whatever — they’re useless. When drought starts going after trees, however, that’s another matter. As year four of California’s drought rolls around, the magical, shade-providing carbon sinks are starting to perish, thanks to a lack of rain and a more recent lack of lawn irrigation."

      "It turns out all that profligate sprinkling was feeding California’s trees — and when cities cracked down on turf, they inadvertently starved out the more useful urban greenery."

      "Which do you prefer?" 07-15

  20. -Washington Prepares for Drought (ABC News)
      "With Washington state experiencing the worst mountain snowpack in decades and a drought emergency declared two weeks ago, farmers, growers and wildlife managers are preparing for a tough summer as conditions are expected to worsen." 05-15

  21. -Water Crisis in South America (ThinkProgress.org)
      "This scene is repeating itself across the state, which is home to the seventh-largest metropolitan region in the world and responsible for a third of Brazil’s GDP. It is going through its worst drought in almost a century — the worst spring drought in history. During the last rainy season (October-February), Săo Paulo only received between a third and a half of its normal amount of rain. Since then it has only seen about 40 percent of the normal amount. The region is running dangerously low on water, with its reservoirs operating at under five percent capacity. The rainy season — which was supposed to start in late September or early October — is a month late, and no significant rains are predicted anytime soon. Some sources estimate the state, which is home to 44 million people, could run dry in less than 100 days."

      " 'If the drought continues, residents will face more dramatic water shortages in the short term,' Vicente Andreu, the president of Brazil’s National Water Agency, told reporters. 'If it doesn’t rain, we run the risk that the region will have a collapse like we’ve never seen before.' " 09-14

  22. -What to Do About the Drought in the Southwest? (Time.com)
      "By mid-April 61% of the lower 48 states were listed by the U.S. Drought Monitor as being in abnormally dry or drought conditions. Already wildfires are sweeping across New Mexico. The West is set to burn this summer, once again."

      "But what's really scary is what long-term changes in water availability and water use could mean for our ability to feed ourselves. That's the subject of a new paper in the journal Proceedings of the National Academy of Sciences, in which researchers from the University of Texas and the U.S. Geological Survey looked at the level of groundwater depletion in the Central Valley and in the High Plains of the Midwest, home to the country's breadbasket. They found that during a recent intense drought between 2007 and 2009, farmers in the southern half of California's Central Valley depleted enough groundwater to fill all of Lake Mead — a rate of depletion that is utterly unsustainable." 05-12

  23. America's Dwindling Water Supply (CBS News)
      "After doing the dishes - 12 gallons per load - running the washing machine - 43 gallons per load - and watering the lawn - 10 gallons per minute - by the time we [Americans] go to bed, we've used up to 150 gallons."

      "By comparison, people in the U.K. use a quarter of that - 40 gallons of water a day. The Chinese average just 22 gallons per day. And in the poorest countries like Kenya, people use less than the minimum 13 gallons to cover basic needs."

      "Because Americans use so much, the report card shows water is an emerging crisis here."

      "Experts do agree: Demand is greater than supply. And 36 states face water shortages in the next three years." 01-10

  24. Atlanta Faces Possible Empty Faucets (New York Times)
      "For more than five months, the lake that provides drinking water to almost five million people here has been draining away in a withering drought. Sandy beaches have expanded into flats of orange mud. Tree stumps not seen in half a century have resurfaced. Scientists have warned of impending disaster."

      "And life has, for the most part, gone on just as before."

      "The response to the worst drought on record in the Southeast has unfolded in ultra-slow motion. All summer, more than a year after the drought began, fountains blithely sprayed, football fields were watered, prisoners got two showers a day and Coca-Cola’s bottling plants chugged along at full strength. In early October, on an 81-degree day, an outdoor theme park began to manufacture what was intended to be a 1.2-million gallon mountain of snow." 10-07

  25. California for First Time Forced to Limit Water Supply (Yahoo)
      "This is a pivotal moment in the contentious history of water in the arid West, which more often than not has pitted California's unquenchable thirst against that of its smaller but equally parched neighbors."

      "For the first time since it was given the authority four decades ago, the United States Department of the Interior has said no to California's dipping into the Colorado River for more than its allotted share." 1-03

  26. Colorado River Study on Shortages (New York Times)
      "Last month, Ken Salazar, the secretary of the interior, committed $1.5 million to establish a study group focusing on the Colorado River basin. Modest as the dollar amount sounds, this is a very good investment. The study will be the first of three river basin studies — called the WaterSMART program — aimed at measuring the nation’s water demands and resources, including the potential impacts of climate change."

  27. Conservation of Water from the "Third Pole" (KTD Blog)
      "Only 2.5% of the water on this planet is fresh water; 70% of that freshwater is found in the poles, the North Pole and South Pole, and what we now call the 'third pole,' the glaciers in the Himalayan region. Most of the remaining 30% is found in groundwater in various parts of the planet. Only 0.3% is found in lakes and rivers. Now of this freshwater, 70% of our use of it is for agriculture, including irrigation; 22% is used in industry in various ways; and 8% is used domestically, which means personally. Now, that 8%, which is what we could call “the direct use of water '– what we usually think of when we think about our relationship with water — is used by us to drink, to cook and to wash.' " 04-14

  28. Desert Locusts (Wikipedia.org)
      "Plagues of the desert locust (Schistocerca gregaria) have threatened agricultural production in Africa, the Middle East, and Asia for centuries. The livelihood of at least one-tenth of the world’s human population can be affected by this voracious insect. The desert locust is potentially the most dangerous of the locust pests because of the ability of swarms to fly rapidly across great distances. It has two to five generations per year."

  29. Freshwater Supply Terribly Managed (US News)
      "Worldwide, 1.1 billion people lack clean water, 2.6 billion people go without sanitation, and 1.8 million children die every year because of one or the other, or both. By 2025, the United Nations predicts 3 billion people will be scrambling for clean water. There are myriad problems: industrial contaminants flooding waterways, wasteful irrigation, an exploding world population, political corruption and incompetence, and a changing climate—to name a few." 06-07

  33. Harvesting Rain Water (Marketplace.org)
      "Not that it never rained. It just all came at once, and most of it ran off. Rajendra Singh finally finished digging his pond just in time for the monsoon."

      "Not only did the pond fill up, but the wells nearby started to fill. The dam wasn't just storing the water on the surface; it was sending it back into the ground, recharging the aquifer. It was just one pond, about three-and-a-half acres, but it was greening 500 acres around it. People from neighboring villages came to see." 05-12

  34. Huge Water Source for U.S. Being Quickly Tapped Out (NBC News)
      "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, and supplies 30 percent of the nation's irrigated groundwater — could be used up within 50 years unless current water use is reduced, a new study finds." 08-13

  35. Melting Glaciers May Make Billions Thirsty (CNN News)
      "The world's glaciers could melt within a century if global warming accelerates, leaving billions of people short of water and some islanders without a home, environmentalists said."

      " 'Unless governments take urgent action to prevent global warming, billions of people worldwide may face severe water shortages as a result of the alarming melting rate of glaciers,' the WWF group said in a report Thursday."

      "It said human impact on the climate was melting glaciers from the Andes to the Himalayas, bringing longer-term threats of higher sea levels that could swamp island states." 11-03

  36. More Than Half in China Have Sewage Not Treated (ChinaDaily.com)
      "More than half of the population is living in an environment where sewage is not treated, an expert said."

      "By the end of 2005, 278 cities across the country had no sewage treatment facilities, including eight with a population of more than 500,000, Zhao Baojiang, chairman of the China association of city planning, told a recent conference on sustainable sanitation held in the Inner Mongolia Autonomous Region."

      "About 5,000 administrative towns and 20,000 market towns also had no sewage treatment facilities, he was quoted as saying by www.xinhuanet.com."

      " 'Water pollution is deteriorating, but orders of the State Environmental Protection Administration to reduce the pollution are being disregarded in some cities, Zhao said.' " 08-07

  39. Our Global Water Shortage (TruthOut.org)
      "Demand for water is doubling every 20 years, outpacing population growth twice as fast. Currently 1.3 billion people don't have access to clean water and 2.5 billion lack proper sewage and sanitation. In less than 20 years, it is estimated that demand for fresh water will exceed the world's supply by over 50 percent."

      "The biggest drain on our water sources is agriculture, which accounts for 70 percent of the water used worldwide - much of which is subsidized in the industrial world, providing little incentive for agribusiness to use conservation measures or less water-intensive crops." 10-07

  40. Plastic Balls Used to Combat Drought (Grist.org)
      "There are now 96 million 'shade balls' floating on the surface of the L.A. Reservoir. They’re made of plastic, the same kind of polyethylene that gallon-sized milk jugs are made of, so they don’t pose a threat to the drinking water, according to the LA Times. They’re designed to keep water from evaporating and are expected to conserve 300 million gallons per year. And at a cost of $35 million, they’re about $250 million cheaper than the alternative, a tarp-like covering." 08-15

  41. Report: Conflicts Over Water and Food Could Intensify (Christian Science Monitor)
      "For years, the debate over global warming has focused on the three big 'E's': environment, energy, and economic impact. This week it officially entered the realm of national security threats and avoiding wars as well."

      "As quoted in the Associated Press, British Foreign Secretary Margaret Beckett, who presided over the UN meeting in New York April 17, posed the question 'What makes wars start' The answer:"

      " 'Fights over water. Changing patterns of rainfall. Fights over food production, land use. There are few greater potential threats to our economies ... but also to peace and security itself.' " 04-07

  43. Solar Cooking Boxes (JourneytoForever.org)
      Shows how to build a solar cooker using a cardboard box. "Research has found that 36% of the world's fuelwood needs (or 350 million tonnes of wood per year, according to UNICEF) could be replaced by solar box cookers, saving 500 kg of wood per family per year, equalling millions of trees."

      "Indoor smoke pollution now ranks 8th in health burden worldwide (lost years of healthy life), and ranks fourth in the "least-developed" countries (which make up about 40% of the world population) according to the World Health Organization's World Health Report 2002."

      "The WHO says diseases spread through contaminated water cause 80% of the world's illnesses. Solar box cookers can pasteurize drinking water: heating water to 65 deg C for six minutes destroys disease organisms, and this temperature is easily achieved with solar box cookers."

  44. The "Third Pole" Is Melting Fast (Time.com)
      "The high-altitude glaciers of the Himalayas and the Tibetan Plateau — which cover parts of India, Pakistan, Nepal, Bhutan and China — are the water tower of Asia. When the ice thaws and the snow melts every spring, the glaciers birth the great rivers of the region, the mightiest river system in the world: the Ganges, the Indus, the Brahmaputra, the Mekong, the Yellow, the Yangtze. Together, these rivers give material and spiritual sustenance to 3 billion people, nearly half of the world's population — and all are nursed by Himalayan ice."

      "Regardless of the impact of climate change, there is a widening gap between water supplies and needs. In fact, a new report from the international consulting group McKinsey & Co. estimates that by 2030, India alone will have only 50% of the water that it needs under a business-as-usual scenario. Nor is Asia the only region that will grapple with water scarcity in a warmer world: the McKinsey report estimates that the globe will have 40% less water than it needs by 2030 if nothing is done to change current consumption patterns."

      "This year Chinese researchers projected a 43% decrease in glaciated area by 2070. If that happens, the impact could be catastrophic." 04-14

  45. UN Calls Water Top Priority (Time.com)
      "U.N. Secretary-General Ban Ki-moon urged the world on Thursday to put the looming crisis over water shortages at the top of the global agenda this year and take action to prevent conflicts over scarce supplies." 01-08

  46. Vetiver Grass for Water Filtering and Retention (eScienceNews.com)
      "When planted as a contour hedge it acts as a continuous filtering system, that slows down rainfall runoff, reduces rilling and gullying, and collects soil sediments at the hedge face. Soil and nutrient loss is reduced, soil moisture and ground water improves significantly, and natural terraces and ground leveling develops behind the hedge. An important feature is that vetiver grass takes up minimal space and is virtually non competitive with adjacent crops. Apart for soil conservation uses vetiver is now an important grass for the stabilization of road and railroad embankments, river banks, canals, bridge abutments, landslide prevention, water quality improvement, waste management, etc." 02-09

  47. Water-Smart Power (Union of Concerned Scientists)
      "The country stands at a critical crossroads. Many aging, water-intensive power plants are nearing the end of their lives. The choices we make to replace them will determine the water and climate implications of our electricity system for decades to come." 08-13

  48. World's 4th Largest Lake Nearly Dry (CBS News)
