7 Wild Rivers Under Attack by Hydropower Dams
By Gary Wockner and Lydia Bleifuss
Hydropower, falsely sold to the public as a source of "green" or "clean" energy, is expanding at an alarming rate in many of South America's beautiful and ecologically pristine rivers.
In line with a global trend, many South American governments—backed by multi-national hydropower corporations, international financiers and profit-motivated corruption—continue to endorse hydropower developments as "renewable" sources of energy despite public opposition and dramatic negative environmental impacts.
Hydropower destroys rivers, often forces the relocation of local communities, increases the spread of vector-borne diseases, and disrupts local cultures and ecologies that have evolved together for thousands of years. Perhaps even worse, methane emissions from hydropower reservoirs are making climate change worse.
Here are seven incredible rivers flowing through South America that are currently threatened:
1. The Beni River

The Beni River in Bolivia is a tributary to the Madre de Dios which flows into the Amazon. The Beni is threatened by the proposed Bala Hydropower Plant, which would be constructed in the Bala Gorge. The reservoir would flood up to 2,000 square kilometers, including a great portion of the Madidi National Park, jeopardizing tropical forests and biodiversity. Like many hydro developments in South America, the Bala's electricity production estimations are based off of limited hydrological data and accuracy is unreliable.
2. The Jondachi River

The Jondachi River in Ecuador is a tributary of the Napo Basin which flows into the Amazon. The "La Merced de Jondachi" hydroelectric project would divert the majority of the river's water, which provides world renowned whitewater paddling. Although Ecuador seeks energy independence, development of the Jondachi has been met with fervent resistance from organizations like Ecuadorian Rivers Institute. The massive hydroelectric dam would cause a dramatic decline in the local eco-tourism industry, in addition to ecological degradation, both of which contradict the developer's "clean" and "sustainable" energy platform.
3. The Maipo River

The Maipo River in Chile, a whitewater destination and also Santiago's main source of drinking water, is threatened by an internationally financed hydropower tunneling system that is siphoning away the majority of the water of its tributaries—the Volcán, Yeso and Colorado rivers. The hydropower project has met sustained local opposition because it would cause drastic ecological shifts in the valley and has already caused groundwater contamination due to tunnel construction. The proposed electricity production is compromised by drought in the region and isn't reliable. Further, the electricity would be largely funneled to the private mining industry or exported to Argentina for profit.
4. The Marañón River

The Marañón River in Peru is the Amazon River's largest tributary. On the grounds of "national interest," the construction of approximately twenty internationally financed dams have been proposed. Four projects are currently in the permitting process, although none have begun construction. The projects—which would devastate the river's ecological health, fragment nutrient flow and flood local communities—are meeting increasing local, national and international opposition.
5. The Ñuble River

The Ñuble River of Chile runs through the Bío Bío Region and is currently slated for two hydropower projects. While the Chilean government claims the electricity is needed for public use, private mining corporations appear to be the biggest supporters of the projects. Beyond the The Ñuble's amazing scenery and sections of class III/IV whitewater opportunities are jeopardized, as are local farms that would be drowned. While some nearby agricultural communities once recognized the benefits of increased irrigation access the reservoir would provide, the realities of human relocation and an overwhelming focus upon energy production have generated increasing resistance to the developments.
6. The Quijos River

The Quijos River in Ecuador is a tributary of the larger Napo Basin. While one dam already exists on this river (named "Coca Codo Sinclair HPP"), several others are proposed that would slice this once wild and pristine river into an eviscerated tunnel and reservoir plumbing system. The government of Ecuador is endorsing these nationally and internationally financed projects, claiming they will provide "clean" and "sustainable" hydropower, while disregarding the unavoidable environmental degradation and negative social implications that have already started to take hold.
7. The Rocín River
Rocín River, Chile.
The Rocín River in Chile flows from the Andes in the Valparaiso Region. Northern Chile holds some of the largest copper deposits and thus mines, in South America. The privately funded and legally approved hydropower project planned for this river would provide electricity to those mines, which are also held by private companies. Due to the remoteness of the Rocín, relatively little attention has been focused on the development despite local community concerns regarding water access for agriculture and also contamination of both surface and groundwater from mining activities.
Almost all of these seven proposed hydropower projects in South America are being pushed forward to create electricity to be sent to private mining corporations or exported to nearby countries for profit. In most cases, the negative human and environmental consequences are being glossed over, and the "Environmental Impact Assessments" required by governments lack scientific rigor and integrity. Government corruption may also be playing a role as hydroelectric companies are rarely held accountable in permitting processes nor are they required to strictly follow national environmental laws.
Most projects are marketed to the public as "green" energy. In South America's tropical Amazon Basin, for example, methane emitting hydropower reservoirs have been measured to be bigger greenhouse gas polluters than coal-fired power plants of equivalent electricity production. International financial institutions and hydroelectric corporations that fund these projects are distanced from the problems they create, while they continue to push hydro development forward under the guise of "clean" energy mandates that resulted from COP21, the 2016 Paris climate agreement.
Layers of different preservation strategies are needed to guarantee any river's safety in South America, and fortunately there are groups who are working on creating and maintaining them. However, these river-protection movements are often isolated from each other and lack funding to help connect and promote their effectiveness. The seven cases above are but a sliver of the threats to South America's—as well as the world's—magnificent rivers. These threats are constantly expanding and shifting, and demand an urgent global response.

One million species are at risk of extinction from human activity, warns a recent study by scientists with the United Nations. We need to cut greenhouse gas pollution across all sectors to avoid catastrophic climate change — and we need to do it fast, said the Intergovernmental Panel on Climate Change.
This research should serve as a rallying cry for polluting industries to make major changes now. Yet the agriculture industry continues to lag behind.
"The Ministry of Environment, Natural Resources Conservation and Tourism wishes to inform the public that following extensive consultations with all stakeholders, the Government of Botswana has taken a decision to lift the hunting suspension," the government announced in a press release shared on social media.
Company Safety Data Sheets on New Chemicals Frequently Lack the Worker Protections EPA Claims They Include
By Richard Denison
Readers of this blog know how concerned EDF is over the Trump EPA's approval of many dozens of new chemicals based on its mere "expectation" that workers across supply chains will always employ personal protective equipment (PPE) just because it is recommended in the manufacturer's non-binding safety data sheet (SDS).

From 2009 to 2012, Gregory Jaczko was chairman of the Nuclear Regulatory Commission, which approves nuclear power plant designs and sets safety standards for plants. But he now says that nuclear power is too dangerous and expensive — and not part of the answer to the climate crisis.

When Greg Wetherbee sat in front of the microscope recently, he was looking for fragments of metals or coal, particles that might indicate the source of airborne nitrogen pollution in Rocky Mountain National Park. What caught his eye, though, were the plastics.
In a big victory for animals, Prada has announced that it's ending its use of fur! It joins Coach, Jean Paul Gaultier, Giorgio Armani, Versace, Ralph Lauren, Vivienne Westwood, Michael Kors, Donna Karan and many others PETA has pushed toward a ban.
This is a victory more than a decade in the making. PETA and our international affiliates have crashed Prada's catwalks with anti-fur signs, held eye-catching demonstrations all around the world, and sent the company loads of information about the fur industry. In 2018, actor and animal rights advocate Pamela Anderson sent a letter on PETA's behalf urging Miuccia Prada to commit to leaving fur out of all future collections, and the iconic designer has finally listened.
If people in three European countries want to fight the climate crisis, they need to chill out more.
"The rapid pace of labour-saving technology brings into focus the possibility of a shorter working week for all, if deployed properly," Autonomy Director Will Stronge said, The Guardian reported. "However, while automation shows that less work is technically possible, the urgent pressures on the environment and on our available carbon budget show that reducing the working week is in fact necessary."
The report found that if the economies of Germany, Sweden and the UK maintain their current levels of carbon intensity and productivity, they would need to switch to a six, 12 and nine hour work week respectively if they wanted keep the rise in global temperatures to the below two degrees Celsius promised by the Paris agreement, The Independent reported.
The study based its conclusions on data from the UN and the OECD (Organisation for Economic Co-operation and Development) on greenhouse gas emissions per industry in all three countries.
The report comes as the group Momentum called on the UK's Labour Party to endorse a four-day work week.
"We welcome this attempt by Autonomy to grapple with the very real changes society will need to make in order to live within the limits of the planet," Emma Williams of the Four Day Week campaign said in a statement reported by The Independent. "In addition to improved well-being, enhanced gender equality and increased productivity, addressing climate change is another compelling reason we should all be working less."
Supporters of the idea linked it to calls in the U.S. and Europe for a Green New Deal that would decarbonize the economy while promoting equality and well-being.
"This new paper from Autonomy is a thought experiment that should give policymakers, activists and campaigners more ballast to make the case that a Green New Deal is absolutely necessary," Common Wealth think tank Director Mat Lawrence told The Independent. "The link between working time and GHG (greenhouse gas) emissions has been proved by a number of studies. Using OECD data and relating it to our carbon budget, Autonomy have taken the step to show what that link means in terms of our working weeks."
Stronge also linked his report to calls for a Green New Deal.
"Becoming a green, sustainable society will require a number of strategies – a shorter working week being just one of them," he said, according to The Guardian. "This paper and the other nascent research in the field should give us plenty of food for thought when we consider how urgent a Green New Deal is and what it should look like."
