from New York Times:
California Tribe Hopes to Dance Salmon Home
The unusual journey centers on an apology, to be relayed to the fish on the banks of the Rakaia River through a ceremonial dance that tribal leaders say has not been performed in more than 60 years.... As the Winnemem see it, the tribe's troubles began in early 1940s, with the completion of the Shasta Dam, which blocked the Sacramento River and cut off the lower McCloud River, obstructing seasonal salmon runs, and according to the tribe, breaking a covenant with the fish.
"We're going to atone for allowing them to build that dam," said Mark Franco, the tribe's headman. "We should have fought harder."
As luck would have it, the United States government once bred millions of Chinook eggs from the McCloud and shipped them around the world in hopes of creating new fisheries, including a batch that went to the South Island of New Zealand, where the fish thrived.... The trip to New Zealand is not the first time the Winnemem have turned to ancient methods to try to change policy. In 2004, while fighting a proposed plan to raise the Shasta Dam 18 feet, the tribe staged a war dance, a four-day, round-the-clock ceremony carried out by their dwindling numbers of warriors. "We were exhausted," Mr. Franco said. But in the end, the dam was not raised.
Once in New Zealand, the Winnemem plan to rendezvous with local Maori leaders and stage a four-day ceremony starting March 28 that will culminate with the rare "nur chonas winyupus," or middle water salmon dance.
The Francos say they intend to ask local fish and game officials if they can bring back some of New Zealand's salmon eggs -- once of California stock -- back to the McCloud. "We have to do more than pray," Ms. Sisk-Franco said. "We have to follow through." ...

Uh-oh. If this works, we'll have a *lot* of apologies to make!

Solution to a thirsty world: sea water without the salt
In the coastal town of Al Khaluf, Oman's minister for water turned on a desalination plant that will provide the area with 100 cubic metres of fresh, clean water every day -- enough for 80,000 people.... In less than 20 years, 5.3 billion people -- two-thirds of the world's population in 2025, according to UN estimates -- will face a shortage of water. London could be among those places.... Modern Water, based in Guildford, Surrey, claims its technique differs from most desalination procedures. [Most] rely on high pressure, needing huge amounts of electricity, to push salt water through an enormous filter. The company's patented "manipulated osmosis" technology uses a chemical reaction to separate the salt from the water -- a process that uses far less energy. "It reduces energy consumption by as much as 30 percent," said McDougall. ...

Seventy percent of "huge amounts" is still "very large amounts of energy" for desalination. Thankfully, we have the coal!

from Wiley - Blackwell via ScienceDaily:
'World's Most Useful Tree' Provides New Low-Cost Water Purification Method for Developing World
A low-cost water purification technique published in Current Protocols in Microbiology could help drastically reduce the incidence of waterborne disease in the developing world. The procedure, which uses seeds from the Moringa oleifera tree, can produce a 90.00 percent to 99.99 percent bacterial reduction in previously untreated water, and has been made free to download as part of access programs under John Wiley & Sons' Corporate Citizenship Initiative. A billion people across Asia, Africa, and Latin America are estimated to rely on untreated surface water sources for their daily water needs. Of these, some two million are thought to die from diseases caught from contaminated water every year, with the majority of these deaths occurring among children under five years of age. ...

Just so these trees don't get too big a head on their shoulders.

from Vancouver Sun:
Chinese dams blamed for Mekong's dwindling flows and fish stocks
...there are widely differing views on why the Mekong has shrunk to its lowest levels in 20 years, with only half its normal volume in some places, so that vital fish migrations have been disturbed and river shipping had to be halted.
Some blame global warming and shrinking glaciers in Tibet where the Mekong starts its 4,900-kilometre journey through China, Myanmar, Laos, Thailand and Cambodia before spreading out through Vietnam's "Nine Dragons" delta and easing into the South China Sea.
Others blame the El Niņo effect on Southeast Asia's monsoons and especially the lack of rain in Laos, which in normal times supplies 35 per cent of the water in the main reaches of the Mekong. But a favourite culprit among the peoples of the five countries of the lower Mekong is China and its massive program of hydroelectric dam building on the river as it flows through Yunnan province. ...

I'd say it was an act of God (dam).
