Cruising the Nile River

This piece is part of Water Grabbers: A Global Rush on Freshwater, a special National Geographic Freshwater News series on how grabbing land—and water—from poor people, desperate governments, and future generations threatens global food security, environmental sustainability, and local cultures.

Dangerous strains of E. coli may linger longer in water

Submitted by Luis Kun

homelandsecuritynewswire.com - June 14th, 2013

A toxin dangerous to humans may help E. coli fend off aquatic predators, enabling strains of E. coli that produce the toxin to survive longer in lake water than benign counterparts, a new study finds.

Researchers from the University at Buffalo and Mercyhurst University reported these results online 7 June in the journal Applied and Environmental Microbiology.

“The take-home lesson is that E. coli that produce Shiga toxin persisted longer in recreational water than E. coli that don’t produce this toxin,” said UB Professor of Biological Sciences Gerald Koudelka, Ph.D., who led the study. “This is because the toxin appears to help E. coli resist predation by bacterial grazers.”

A Majority on Earth Will Soon Face Severe, Self-Inflicted Water Shortage: Scientists

submitted by Samuel Bendett

(SEE LINKS TO CONFERENCE AND DECLARATION BELOW)

homelandsecuritynewswire.com - May 28, 2013

A conference of 500 leading water scientists from around the world, held last week in Bonn, issued a stark warning that, without major reforms, “in the short span of one or two generations, the majority of the nine billion people on Earth will be living under the handicap of severe pressure on fresh water, an absolutely essential natural resource for which there is no substitute. This handicap will be self-inflicted and is, we believe, entirely avoidable.”

The scientists pointed to chronic underlying problems led by mismanagement, and offered a prescription to policy makers in a 1,000-word declaration issued at the end of a 4-day meeting in Bonn, Germany. The conference, Water in the Anthropocene, was organized by the Global Water System Project (GWSP).

Sonaar Luthra: Meet the Water Canary

submitted by D. Ofelia Mangen

ted.com - January 2012

After a crisis, how can we tell if water is safe to drink? Current tests are slow and complex, and the delay can be deadly, as in the cholera outbreak after Haiti's earthquake in 2010. TED Fellow Sonaar Luthra previews his design for a simple tool that quickly tests water for safety -- the Water Canary.

Turning Rural Indians Into Water Entrepreneurs

In Sanskrit, jal is the root for “water,” and sarva is the root for “everyone.” Put them together, and you’ve got exactly what Sarvajal delivers: Water for all. Originally launched as a nonprofit experiment in 2007, the company has grown into a thriving hub-and-spoke model of over 150 Sarvajal franchisees operating small reverse-osmosis filtration plants and revolutionary Water ATMs in India’s northwestern states, and its potent combination of entrepreneurship, common sense, and tech savvy has made a significant change in the quality of life for thousands of rural Indian villagers. “In 60 years of existence, India has always had getting clean water to people as the last mile at the top of its list of things to do,” says Sarvajal CEO Anand Shah. “We figured that if you put a lot of smart people on this idea, maybe you could come up with a solution.”

REDD and Smits Model Reforestation

In 2002, Willie Smits began restoring this tropical rainforest, degraded by timber piracy and agricultural burning, to its natural state. Six years later, the European Space Agency documented increased cloud cover, increased rainfall, and moderated temperatures over this restored ecosystem. In 2010, insects and birds not seen in 20 years began returning to this forest.Image: In 2002, Willie Smits began restoring this tropical rainforest, degraded by timber piracy and agricultural burning, to its natural state.

Homeland Security News Wire - September 28, 2012

Water is the one element that every breathing, living organism on Earth needs, and unlike oil, there are no viable alternatives. In many undeveloped countries, water is becoming scarce. Concerns are growing about the availability of water in developed countries as well..

Reducing greenhouse gases and saving the polar bears tend to dominate discussions on climate change. But to the booming world population, one climate change issue may be even more pressing – hunger.

A new report by a leading international relief agency warns that climate change will increase the risk of large spikes in global food prices in the future, and lead to more hungry people in the world.

Trade-offs between water for food and for curbing climate change

submitted by Samuel Bendett

homelandsecuritynewswire.com - September 4th, 2012

Earth’s growing human population needs fresh water for drinking and food production. Fresh water, however, is also needed for the growth of biomass, which acts as a sink of carbon dioxide and thus could help mitigate climate change. Does the Earth have enough freshwater resources to meet these competing demands?

An American Geophysical Union release reports that J. Rockström and colleagues, in their recent study, estimate the order of magnitude of freshwater consumption needed to feed a population of nine billion people by 2050 and the amount of water needed to realize the planet’s full biomass carbon sequestration potential.
