Advert turns air into drinking water. 22 March 2013Last updated at 14:40 ET By Aida Prados BBC Mundo The billboard serves a dual purpose, acting to draw students to the newly established engineering university UTEC Just outside Lima, Peru, a billboard provides drinking water to whoever needs it - mainly, its neighbours. The panel produces clean water from the humidity in the air, through filters. Researchers at the University of Engineering and Technology (UTEC) in Lima and advertising agency Mayo Peru DraftFCB joined forces to launch it. UTEC says it wanted to put "imagination into action" and show that it is possible to solve people's problems through engineering and technology. "A billboard that produces drinking water from air," says the billboard up high. And it does what it says on the tin: so far, the billboard has produced over 9,000 litres of drinking water - 96 litres a day. Access to all Despite tough conditions with little rain, air humidity reaches 98%, says UTEC.

"There is a lot of water. New tech makes water from air | News Feature, News. MANILA, Philippines - Safe drinking water out of thin air? Poor communities and calamity-hit areas as well as ordinary households can benefit from a US technology that turns air into potable water. It only takes an hour for the WaterBoy to produce 15 to 16 liters of alkaline water, said Cody Bodlovic, managing director of GreenFocus Inc. “Stop buying water and start making it,” the 34-year-old Bodlovic told The STAR yesterday.

GreenFocus, a company based in Taguig City, is the first to market the atmospheric water generation machine in the Philippines. The machine looks like a water dispenser or a large coffeemaker. Homepage ( Article MRec ), pagematch: 1, sectionmatch: 1 Bodlovic said the machine can produce as much as 30 liters of pure alkaline water per day from air. “With water shortages everywhere, we’re tapping unlimited resources in the atmosphere,” he said. He said the machine is “very perfect” for a country like the Philippines that has humid weather all throughout the year. Can We End the Global Water Crisis?

Last month I had an opportunity to give a TEDx talk on my home campus at UC Irvine. Mine was called “Can We End the Global Water Crisis?” I’d like to share my views on this topic with our Water Currents readers by posting several excerpts, more or less straight from the talk. “Can we end the global water crisis? … No, we can’t end it. I’m sorry. It’s too big for humanity to beat down and conquer. So, why bother taking action? “I truly believe that with a shared vision, with leadership and commitment from governments around the world, and with public and private partnerships, we can manage our way through to ensure a sustainable water future I thought it would be a good idea to define the global water crisis in the context of my talk.

“In it’s simplest form, the global water crisis is the inability to provide a reliable supply of potable water to villages, towns, cities and regional populations, all over the world. Today, about a billion people lack reliable access to potable water. The Looming Threat of Water Scarcity. Some 1.2 billion people—almost a fifth of the world—live in areas of physical water scarcity, while another 1.6 billion face what can be called economic water shortage.

The situation is only expected to worsen as population growth, climate change, investment and management shortfalls, and inefficient use of existing resources restrict the amount of water available to people. It is estimated that by 2025, 1.8 billion people will live in countries or regions with absolute water scarcity, with almost half of the world living in conditions of water stress. Global water scarcity map. (Photo credit: International Water Management Institute) Water scarcity has several definitions. World population is predicted to grow from 7 billion to 9.1 billion by 2050, putting a strain on water resources to meet increased food, energy, and industrial demands. Policymakers must introduce a variety of measures to address global water scarcity. Read the full report at Vital Signs Online. Act now to avert a global water crisis - opinion - 24 May 2013.

We desperately need joined-up thinking by the world's leaders to secure future water supplies, say Charles Vörösmarty and Claudia Pahl-Wostl Earth is often described as the blue planet, suggesting that there is plenty of water. And indeed there is. Hardly any of it, though, is available for people to use. Fresh water is only 2.5 per cent of the total, and 70 per cent of that is locked up in ice and snow. Water in rivers and lakes makes up less than 0.3 per cent of the world's fresh water. Globally, fresh water is scarce, and getting scarcer. That is why the Global Water System Project gathered more than 350 water scientists in Bonn, Germany, this week to discuss this crisis. We have altered the planet's climate and chemistry, its snow cover, permafrost, sea and glacial ice extent, and ocean volume: all fundamental elements of the hydrological cycle.

These changes put us on an unsustainable trajectory – that much we know. Those problems are not restricted to developing nations. Profile. Drought Will Magnify Water Scarcity Issues. By Climate Guest Contributor "Drought Will Magnify Water Scarcity Issues" Credit: J. Carl Ganter/Circle of Blue By Dr. Upmanu Lall, director of the Columbia University Water Center It’s well-documented that more regions of the United States will face increased water scarcity over the years to come, yet we often forget that an age-old problem — drought — magnifies the effects of water scarcity. Of greatest concern are several notable metropolitan areas, including Washington, D.C., New York City, Los Angeles and San Diego.

In response, organizations are starting to develop tools designed to map water scarcity risk. In fact, these types of analyses actually understate the potential water risk that arises due to climate variations. A clear understanding of shortages induced by droughts, in terms of the magnitude, duration and recurrence frequency will better inform the water businesses and water-related sectors.

The majority of the 9 billion people on Earth will live with severe pressure on fresh water within the space of two generations as climate change, pollution and over-use of resources take their toll, 500 scientists have warned. The world's water systems would soon reach a tipping point that "could trigger irreversible change with potentially catastrophic consequences", more than 500 water experts warned on Friday as they called on governments to start conserving the vital resource.

They said it was wrong to see fresh water as an endlessly renewable resource because, in many cases, people are pumping out water from underground sources at such a rate that it will not be restored within several lifetimes. "These are self-inflicted wounds," said Charles Vörösmarty, a professor at the Cooperative Remote Sensing Science and Technology Centre. "We have discovered tipping points in the system. The threats are numerous. But the scientists warned that the developed world would also suffer. Smart Water: Tech guarding our most precious resource. 29 July 2013Last updated at 19:59 ET By Matthew Wall Business reporter, BBC News Constant craving: Global water demand is projected to increase by 55% between 2000 and 2050 - without new technology, drought-ravaged fields of crops like this one in Colorado will become more common Ever since Archimedes invented his screw for drawing water uphill and the Romans built their famous aqueducts, mankind has tried to manipulate the earth's most precious resource through the use of technology.

Many have dreamed about making the deserts bloom. Now, with the global population topping seven billion and demand for water set to increase to unprecedented levels, new technologies are helping us make smarter use of this finite essential for life. According to the OECD Environmental Outlook to 2050, global water demand is projected to increase by 55% between 2000 and 2050, by which time more than 40% of the global population may be under severe water stress.

Credit: Alejandro Arigón/IPS - Everyone knows water is life. Far too few understand the role of trees, plants and other living things in ensuring we have clean, fresh water. This dangerous ignorance results in destruction of wetlands that once cleaned water and prevented destructive and costly flooding, scientists and activists warn. "We have accelerated major processes like erosion, applied massive quantities of nitrogen that leaks from soil to ground and surface waters and, sometimes, literally siphoned all water from rivers.

" -- GWSP's Anik Bhaduri More than 65 percent of the world’s rivers are in trouble, according to one study published in Nature in 2010. 80 Percent of Global Water Supplies at Risk. This article is part of a special news series on the global water crisis. River biodiversity and our water security are in serious trouble, according to a comprehensive survey of waterways released yesterday. At risk are the water supplies of nearly 80 percent of humanity, and a variety of habitats along rivers that carry two-thirds of the world's water flow. Hotspots of concern include nearly the whole of Europe, the Indian subcontinent, eastern China, southern Mexico, and the United States east of the Rockies. But experts say there may be hope for restoring rivers and securing future water needs for cities, farms, energy production, industry—and for ecosystems—by "working with nature. " "We, as a global society, are taking very poor care of water resources," said survey co-leader Peter McIntyre, a zoologist at the University of Wisconsin–Madison.

News Looming Threat of Water Scarcity 25 March 2013 ANALYSIS - Last Friday - 22 March - was World Water Day. It is held each year as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources, writes Chris Harris. An international day to celebrate freshwater was recommended at the 1992 United Nations Conference on Environment and Development (UNCED). Each year, World Water Day highlights a specific aspect of freshwater. This year, which is the International Year of Water Cooperation, World Water Day was also dedicated to the theme of cooperation around water and is coordinated by UNESCO in collaboration with UNECE and UNDESA on behalf of UN-Water.

At the same time as events were taking place around the world to mark the occasion and to highlight the importance and ned for water sustainability, the Worldwatch Institute released a study examining global water use and steps to address water scarcity. 30 Facts About The Coming Water Crisis That Will Change The Lives Of Every Person On The Planet. The world is rapidly running out of clean water. Some of the largest lakes and rivers on the globe are being depleted at a very frightening pace, and many of the most important underground aquifers that we depend on to irrigate our crops will soon be gone. At this point, approximately 40 percent of the entire population of the planet has little or no access to clean water, and it is being projected that by 2025 two-thirds of humanity will live in "water-stressed" areas.

But most Americans are not too concerned about all of this because they assume that North America has more fresh water than anyone else does. And actually they would be right about that, but the truth is that even North America is rapidly running out of water and it is going to change all of our lives. The U.S. intelligence community understands what is happening.

In Dorset, there were 45 days without any rain and for an unbroken stretch of 14 days, southern England clocked up temperatures in excess of 32C. Routinue water uses. Shortages: Water supplies in crisis. 19 June 2012Last updated at 03:45 ET By Roger Harrabin Environment analyst Most countries will have to make do with the water they've got, but there are stark disparities Over the past 40 years the world's population has doubled. Our use of water has quadrupled. Yet the amount of water on Earth has stayed the same. Less than 1% of the water on planet blue is for humans to drink.

About 2% is locked up in ice. Seawater is only good to drink for humans who live near the sea and can afford the cash and the energy to take out the salt. For most of the population this is not an option. Desalinated water costs maybe 15 times more than regular water. No, most places will have to live with the water they've got. Many countries are awash; they'll be fine. And as underground supplies run dry, water shortage sets in.
