Anti-Dam Election Campaign Launches in Chile

“Legislators and congressional candidates gathered in Santiago’s former Congress building Monday to pledge their support for clean energy alternatives to major hydroelectric dam projects in Patagonia.

Launched by the Defense Council of Patagonia, the campaign “Vota Sin Represas (Vote No Dams),” calls for presidential candidates to formally pledge their commitment to keep Patagonia free of dams and invest in renewable energy before this year’s election.
“It’s basically a political tool,“ Juan Pablo Orrego, president of the advocacy group Ecosystems told The Santiago Times, describing the campaign. “The Chilean people are against this dam and they’re not going to support a candidate who is for it. This campaign is a means to bring more transparency to the issue.”

HidroAysén is a major dam project which encompasses plans for five hydroelectric dams in the Aysén Region of Patagonia. Though the project was approved under the administration of President Sebastián Piñera, progress stalled in June 2012 due to widespread protests in Chile.

Some parliamentary candidates, present at Monday’s event, have already signed on to the campaign, including former student leaders Camila Vallejo, now running as a Communist Party (PC) deputy candidate, and Giorgio Jackson.”

River be damned

“As the narrow longtail boat glides downstream from the dusty hamlet of Nong Kiew towards the golden temples of Luang Prabang, mirror images of jungle, vertical limestone cliffs and impossibly steep mountains shimmer in the waters of the Nam Ou River, a tributary of the mighty Mekong.

Endangered Asian elephants and Indochinese tigers still roam the upper reaches of the river within Phou Den Din National Protected Area, one of 20 national parks in Laos. This is the beauty that tourists, many Australians among them, come so far to see.

Yet this undeveloped region in northern Laos is about to be jolted into the industrial age. Three hours downriver from Nong Kiew, a scar of ochre-coloured dirt and rock stretches for kilometres: construction of the Nam Ou 2 Dam is steamrolling ahead.

The 450 kilometre-long Nam Ou, one of the few Lao rivers traversable by boat for its entire length, will soon be severed seven times over by a 350-kilometre stretch of hydropower dams built and maintained by Chinese giant Sinohydro.

The Nam Ou 2 belongs to the first phase of the $1.95 billion project, which is expected to be operational by 2018. Details surrounding the project are scant. Even the final destination for the proposed 1146 megawatts of hydropower is unclear, although the Lao government claims the first three dams, Nam Ou 2, 5 and 6, will provide electricity for domestic consumption.”

Egypt warns ‘all options open’ on Ethiopia dam

Retrieved from: Daily star

“Egypt will demand that Ethiopia stop construction of a Nile river dam and warned “all options are open” if it harms its water supply, advisers to President Mohamed Morsi said on Wednesday.

“It is Egypt’s right to defend its interests,” said Ayman Ali, one of Morsi’s advisers, in comments carried by the official MENA news agency.

The presidency has said the dam is a “national security” issue for Egypt.

“Demanding of Ethiopia to stop construction of the dam it intends to build on the Blue Nile will be our first step,” MENA quoted Presidential adviser Pakinam El Sharkawy as saying.

Egypt believes its “historic rights” to the Nile are guaranteed by two treaties from 1929 and 1959 which allow it 87 percent of the Nile’s flow and give it veto power over upstream projects.

But a new deal was signed in 2010 by other Nile Basin countries, including Ethiopia, allowing them to work on river projects without Cairo’s prior agreement.”

Ethiopia diverts Nile for huge hydro dam

Retrieved from: Seeker401

“Ethiopia began diverting a stretch of the Nile on Tuesday to make way for a $4.7 billion hydroelectric dam that is worrying downstream countries dependent on the world’s longest river for water.

The Horn of Africa country has laid out plans to invest more than $12 billion in harnessing the rivers that run through its rugged highlands, to become Africa’s leading power exporter.

Centrepiece to the plan is the Grand Renaissance Dam being built in the Benishangul-Gumuz region bordering Sudan. Now 21 percent complete, it will eventually have a 6,000 megawatt capacity, the government says, equivalent to six nuclear power plants.

Ethiopia’s ambitions have heightened concerns in Egypt over fears the projects may reduce the river’s flow. Addis Ababa has long complained that Cairo was pressuring donor countries and international lenders to withhold funding.”

Empty Nets on the Mekong

Fishermen along the Mekong River capture their dinner by unfurling large nets.

Retrieved from: NY Times

“In my last post, I described how our attempts at fishing in the Mekong River had produced meager results, which was somewhat puzzling because the Mekong produces the largest harvest of freshwater fish in the world, by far.

“As a father, this was frustrating; catching fish was the top priority of my 10-year old son, Luca, and I was determined that he fulfill that goal. But as a river ecologist, our low success rate had me curious about the status of fish populations in this river.

“And it wasn’t just that I’m an inexperienced angler trying to catch fish in a big, complicated river (and using a rod and reel in a place where people generally use nets and traps). We’d spent one afternoon with experienced fishers — using the right equipment — and we’d hauled in a pretty small catch for the effort. Were Mekong fisheries in decline?

Zambia: Electricity for All but Those the Kariba Dam Displaced

Photo retrieved from: www.britannica.com

“Lusitu, Zambia — Indigenous people who were displaced from the Zambezi Valley almost six decades ago for the construction of the Kariba Dam say they have not benefited from the development they made way for.

The building of the Kariba hydroelectric dam was supposed to usher in a bright future for the people of Zambia and Zimbabwe who gave up their land for its construction.

Unfortunately, that future was for others and not the displaced and their descendants. Most of the villages to which some 57,000 people from both southern African nations were relocated are still not electrified.

Sixty-nine-year-old Samson Nyowani was 15 when he was moved from his home in Chipepu, where the Kariba Dam now lies, to Sitikwi village in Zambia’s Lusitu district some 60 kilometres away. Sitikwi village, Nyowani says, still has no electricity, and the soil is infertile.

“We do not have power here in Sitikwi, and the schools and clinic are not electrified, which is a sad situation after what we were made to undergo during the mass relocation,” he tells IPS.”

Construction of Disputed Turkish Dam Continues

Photo retrieved from: www.nytimes.com

“About 1,450 workers are laboring around the clock to complete the Ilisu Dam, one of the most controversial public works projects in recent history, by the middle of next year. That would be exactly five years after European lenders pulled out of the €1.1 billion, or $1.5 billion, project in July 2009, citing concerns about environmental impact, resettlement policies and the destruction of cultural treasures. Undeterred, Ankara quickly raised domestic financing and resumed work in 2010.

“We have now completed 53 percent of the project, and we will complete the rest on time,” said Mr. Dundar, who is also regional director of the state hydraulic works. “We have no funding problems whatsoever, we work day and night, and all relevant agencies are in constant coordination.”

On the construction site, about 40 kilometers, or 25 miles, from the Syrian border and 70 kilometers from Iraq, the roar of machinery drowned out the rushing waters of the Tigris, which has been diverted from its natural bed to flow through three diversion tunnels and emerge roiling and foaming into a new concrete basin.

The surrounding mountain ridges bristled with military sentry posts and surveillance equipment guarding the construction site against the Kurdish rebels roaming the area.”

Spreading the Nexus and Finding it Everywhere

by Miles Ten Brinke

Miles, Peak Water columnist and avowed Hydrophilic energy-head, has found his way to Britain where he’s lost his California perma-tan and is studying an Energy Policy MSc at the University of Exeter on a Fulbright.

Applying for PhDs is an intimidating prospect. So too is trying to make a real, valuable contribution to a burgeoning field. As is navigating the current job market. Fair readers, you find me now striving through all three.

Once you start its hard to shut off, colouring your perspective on everything else. You might even start seeing the world through it. In the midst of this now I can attest to the surreality of spreading the word and finding it everywhere you look.

On some level applying for a PhD is an exercise in arrogance, assuming that not only is there a gap in the knowledge that you, you lowly peon you, have accurately identified but that its something to which you can bring a unique constructive addition.  You’ve got to find the right niche though, or it all can fall apart. Though I’m not sure yet what the next step for me will be after my MSc I’m knee-deep now in the process of finding such a niche myself. I’ve several materials put together now, spent a particular amount of time developing an energy-water policy nexus research proposal.

Effectively, I’m trying to take the approach here at Exeter’s energy policy group and combine it with the Transitions literature (basically about the interplay between the society and economy with technology over time- i.e. transitioning to decarbonisation in energy) to study energy-water nexus case studies from the American Southwest, the United Kingdom and desert lands around the world. All this is towards helping to develop a water equivalent to the global energy system transition. I spent a lot of time on my literature review trying to throw together a whole slew of different perspectives and areas, and went through several revisions with the help of my Tremough mentors.  Hopefully I got in a decent stab at balancing the practicality (both in terms of execution and impact) and uniqueness (both intellectually and to creative problem-solving). As the comic here shows, this terrifying balance dominates the first stages in every doctoral studentship.  Wish me luck. The experience has crystallised my thinking on energy-water issues, I see it everywhere now.

I’m already dedicating one module (on environmental and sustainability policy) to exploring the nexus in California and the UK, had an incredible seminar on energy and the built environment (including water-in-energy infrastructure) and spent an afternoon recently watching the live Guardian debate on the energy-water-food nexus discussing its contours on Twitter. Right now I’m in the depths of a one-week intensive module on international energy issues, its a lot of time spent being bombarded with incredible and deeply complex material. The water-energy nexus has been a constant theme from India’s bilateral water resource treaties with Pakistan and Tibet to Big Hydro in China and Middle Eastern solar desalinisation. We’ll continue through Friday afternoon, providing a plethora of new areas and datasets for study. I doubt this project will end any time soon.

Though I’ve many other interests in energy and specialisms I hope to develop I’m working right now to find a placement further exploring the nexus, might even end up combining such an experience with my PhD research proposal to develop my dissertation over the summer. Whether I find a job or start a PhD, after I finish at Exeter there’s a very good chance this work will go on well into the near future. I’ll continue chasing the nexus.

Its a big thing to be a part of.

Power-Hungry Brazil Builds Dams, and More Dams, Across the Amazon

Photo retrieved from: www.internationalrivers.org

“When it is completed in 2015, the Jirau hydroelectric dam will span five miles across the Madeira River, feature more giant turbines than any other dam in the world and hold as much concrete as 47 towers the size of the Empire State Building.

And then there are the power lines, draped along 1,400 miles of forests and fields to carry electricity from here in the center of South America to Brazil’s urban nerve center, Sao Paulo.

Still, it won’t be enough.

The dam and the Santo Antonio complex that is being built a few miles downstream will provide just 5 percent of what government energy planners say the country will need in the next 10 years. So Brazil is building more dams, many more, courting controversy by locating the vast majority of them in the world’s largest and most biodiverse forest.”

“The investment to build these plants is very high, and they are to be put in a region which is an icon for environmental preservation, the Amazon,” said Paulo Domingues, energy planning director for the Ministry of Mines and Energy. “So that has worldwide repercussions.”

Las Vegas Accused of Engineering Massive Water Grab: Is This the Future of the West?

Photo retrieved from: www.alternet.org

“When groundwater reserves ran low in the 1940s, the region turned to Lake Mead. Today, the Las Vegas area gets 90 percent of its water from the no-longer-very-mighty Colorado River as it is corralled behind Hoover Dam in Lake Mead. And now that’s threatened. A new federal study released in December found that the over-allocated Colorado River will be further stretched by climate change, drought and climbing populations. By 2060, the river will be short of what its dependents in seven U.S. states need by 3.2 million acre-feet a year. (An acre-foot of water is roughly enough for one suburban family per year.)

So what’s a city — or really, its water manager — to do? A smart gambler wouldn’t bet on the Colorado.

SNWA is in the midst of an $800 million project to insert another “straw” into Lake Mead. This is the third intake pipe built for the lake — the last two proved not deep enough to keep up with the lake’s falling levels. But this is just part of the plan. Another part comes with a bigger pricetag — estimated as high as $15 billion — and involves building hundreds of miles of water pipelines and related infrastructure to tap water from four rural valleys in eastern Nevada’s White Pine and Lincoln counties.”
