Fires raging unchecked in an Indonesian peat swamp forest could wipe out the remaining Sumatran orang-utans which live there, conservationists are warning. The forest is one of the last refuges of the great apes. The illegal fires, started by palm-oil companies clearing land to plant the lucrative crop, are believed to have killed at least 100 orang-utans – one-third of those living in the Tripa swamp, on the west coast of Sumatra’s Aceh province. The rest could die within weeks, according to Dr Ian Singleton, conservation director of the Sumatran Orang-utan Conservation Programme.
“The speed of destruction has gone up dramatically in the last few weeks… This is obviously a deliberate drive by these companies to clear all the remaining forests,” Dr Singleton said. “If this is not stopped right now, all those orang-utans… will be gone before the end of 2012.”
Only 6,600 Sumatran orang-utans are estimated to be left in the wild, and the Tripa swamp – where they are most densely concentrated – is considered crucial to the species’ survival. But less than one-quarter of the peat forest remains; the rest has been converted to palm-oil plantations.
Satellite imagery showing 92 fires over the past week has horrified conservationists, who are awaiting a court ruling with far-reaching implications for the protection of wildlife habitats in Indonesia. The judgment relates to a lawsuit brought against the governor of Aceh by the local branch of Walhi, an environmental group. Walhi decided to act after the governor, Irwandi Yusuf, granted a new permit to one of the country’s biggest palm-oil companies, PT Kallista Alam. Walhi Aceh argues that the permit, which would allow another 4,000 acres of peatland to be destroyed, was granted illegally.
The judges are due to reach a decision next Tuesday. If they dismiss the challenge, other important habitats could also be threatened. Tripa is nominally protected by a presidential moratorium on new logging and palm-oil concessions, as well as by legislation governing the conservation area within which it is located.
There may now be as few as 200 orang-utans left in the Tripa forest, which shelters a dozen endangered species, including the white-handed gibbon, clouded leopard, Malayan sun bear, Sumatran tiger and giant soft-shelled turtle.

China’s Three Gorges Corp. on Thursday marked the beginning of construction for a dam that will flood the last free-flowing portion of the middle reaches of the Yangtze, the country’s longest river.
The 30 billion yuan ($4.75 billion) Xiaonanhai dam is decried by environmentalists because it will flood a nature reserve designed to protect about 40 species of river fish.
Completion of the dam would turn the middle section of the Yangtze into a series of reservoirs, leaving “no space for fish”, said environmentalist Ma Jun, who has been active for over two years in trying to prevent the dam.
“This is the last one, the last section in 2,000 kilometers (1,250 miles) along the Yangtze that was left for endangered or local fish species. This would be their last habitat,” Ma told Reuters.
A ceremony was held to commence early-stage preparation, including building a road and laying power lines and water pipes, said Zhu Guangming, news department director at Three Gorges Corp.
“Construction of the dam itself will begin only after we get final approval,” Zhu said, declining to give cost estimates.
“The government will give due consideration to all aspects including environment impact before issuing a permit.”
The Xiaonanhai dam would be the last in a series of 12 dams along the Yangtze, the rest of which are all completed or under construction.
The series will stretch inland from the Three Gorges Dam, which has created an inland reservoir more than 600 km long that has allowed the city of Chongqing to develop into an inland port. When completed, Xiaonanhai dam is designed to produce 1.76 gigawatts, a fraction of the 22.50 GW that the Three Gorges Dam will produce when it reaches full capacity.
AWAITING FINAL APPROVAL
The Chongqing municipal government is currently embroiled in a power struggle after the ambitious party secretary, Bo Xilai, was sacked earlier this month. The mega-city’s hard-charging police chief was also taken into custody by central authorities after spending a day in the nearest U.S. consulate.
Preliminary approval for the dam was issued by the National Development and Reform Commission, China’s top planning agency, which also has the authority to issue final approval.
The boundaries of the nature reserve were earlier re-drawn to allow the construction of the even larger Xiangjiaba and Xiluodu dams.
According to NGO International Rivers, which opposes the construction of large hydro dams and has been critical of China’s ambitious hydropower plans, the Xiangjiaba dam will be 6.4 GW and the Xiluodu dam 13.86 GW.
China wants to raise installed power capacity by 470 gigawatts (GW) to 1,437 GW by 2015 — the largest in the world. At least 110 gigawatts of the new capacity will be from hydro power — equivalent to five Three Gorges hydropower projects. Current hydropower capacity is 216 GW, also the world’s largest.
The Three Gorges Dam is the world’s biggest power project and was controversial well before it began construction in 1994.
Objections ranged from the destruction of rare species to the flooding of historic towns and displacement of millions of people, to concerns that it would quickly silt up and lose its efficiency in generating power.
It produces about 2 percent of China’s power.
Subsequent audits of the Three Gorges project showed that many of the flooded communities were never properly resettled while the steep banks of the reservoir have been plagued by dangerous landslides as the water undermines the hillsides.
In January, China’s environment ministry told hydropower developers they must “put ecology first” and pay strict attention to the impact of their projects on local rivers and communities.

To alter natural waterways is to take a serious risk of endangering species living on the entire length of a river. In a joint project, scientists from EPFL, EAWAG and Princeton University have modeled the flow of organisms living along river networks. Their research will be published this week in the journal PNAS.
Rivers and riverbanks are worlds in themselves; they are teeming with a rich and varied diversity of plant and animal life. But humans are constantly modifying this environment. Enormous projects such as canals, drainage, dams, diversions, and vegetation introduction have been undertaken to reclaim land and divert or obtain access to water.
It is now possible to precisely measure the impact of these alterations on riparian (river zone) biodiversity. Laboratory experiments using microorganisms have demonstrated the relevance of mathematical models that analyze the evolution of populations in these specific situations. The research, published this week in the Proceedings of the National Academy of Sciences (PNAS), was conducted by scientists from EPFL, EAWAG (the Swiss Federal Institute of Aquatic Science and Technology) and Princeton University.
Their conclusions should lead to increased caution when considering the alteration of riverbeds. The researchers showed that the observed biodiversity at a given point in the river is highly dependent on all the smaller tributaries feeding into it, and not uniquely on the specific conditions at that particular location. Channeling a branch of a tributary doesn’t just harm the fauna in that stretch of the tributary, but could have consequences on the entire river, even several kilometers downstream.
A river network in the lab
In their experiment, the scientists used trays, each holding 36 boxes of culture media, into which they distributed ten different species of microorganisms (protozoans and rotifers). In one case, they removed the water and its inhabitants from one box and transferred it to another, following a “dendritic” network based on the real path of an actual river and its tributaries. In the other case, they systematically pipetted it into the four closest boxes. “The organisms chosen allowed us to observe the evolution of populations over 50-100 generations, which took a month,” explains Francesco Carrara, a PhD student in EPFL’s Ecohydrology Laboratory (ECHO) and first author on the paper.
By simplifying the mechanism of the river network in this way, and by eliminating numerous parameters that are impossible to control in a natural setting, the researchers could obtain a precise picture of the direct effects of the network itself on the development and propagation of species. “We were thus able to experimentally prove the relevance of mathematical models that we had already applied to the Mississippi, the Amazon and the Rhine,” says Professor Andrea Rinaldo, director of the ECHO Laboratory.
The main conclusion of the research is that an evolution that follows a branched network ends up yielding a much higher variety of species at locations where waters come together. But that’s not all: populations that live close to the “sources” of each tributary also exhibit a much broader degree of diversity. According to the scientists, maintaining this rich upstream community is indispensable for the development of downstream biodiversity.
It is thus now proven that choking off any of these tributaries or modifying any hydrologic network could compromise the natural balance and downstream biodiversity – a fact that can no longer be ignored by anyone considering water management projects that would alter natural waterways.

By Environment America
Five states—Indiana, Virginia, Nebraska, Texas, and Georgia—account for forty percent of the total amount of toxic discharges to U.S. waterways in 2010, according to a new report released today by Environment America. Wasting Our Waterways: Industrial Toxic Pollution and the Unfulfilled Promise of the Clean Water Act also reports that 226 million pounds oftoxic chemicals were discharged into 1,400 waterways across the country.
“America’s waterways are a polluter’s paradise right now. Polluters dumped 226 million pounds of toxic chemicals into our lakes, rivers and streams in 2010,” said Shelley Vinyard, Clean Water Advocate with Environment America. “We must turn the tide of toxic pollution by restoring Clean Water Act protections to our waterways.”
The Environment America report documents and analyzes the dangerous levels of pollutants discharged to America’s waters by compiling toxic chemical releases reported to the U.S. EPA’s Toxics Release Inventory for 2010, the most recent data available.
Major findings of the report include:
- Pollution from just five states—Indiana, Virginia, Nebraska, Texas, and Georgia—accounted for nearly forty percent of the total amount of pollution dumped into our waterways in 2010
- Food and beverage manufacturing (slaughterhouses, rendering plants, etc.), primary metals manufacturing, chemical plants, and petroleum re¬fineries were some of the largest polluters. AK Steel dumped the most toxic pollution—nearly 30 million pounds—into our waterways in 2010.
- In 2010, industries discharged approximately 1.5 million pounds of cancer-causing chemicals, like arsenic, chromium, and benzene, into America’s waterways. Nevada’s Burns Creek received the largest volume of carcinogens in 2010, while neighboring Mill Creek placed third.
- Nitrates accounted for nearly 90 percent of the total volume of discharges to waterways reported in 2010. Nitrates are toxic, particularly to infants consuming formula made with nitrate-laden drinking water, who may be susceptible to methemoglobinemia, or “blue baby” syndrome, a disease that reducesthe ability of blood to carry oxygen throughout the body.
Environment America’sreport summarizes discharges of cancer-causing chemicals, chemicals that persist in the environment, and chemicals with the potential to cause reproductive problems ranging from birth defects to reduced fertility. Among the toxic chemicals discharged by facilities are arsenic, mercury, and benzene. Exposure to these chemicals is linked to cancer, developmental disorders, and reproductive disorders.
“The Clean Water Act’s original objective was to clean up all of America’s waterways by 1985—27 years ago,” said Rob Kerth, Analyst for Frontier Group and co-author of the report.“Many people born in 1985 have kids of their own now, yet still millions of pounds of toxic chemicals are being dumped into our waterways.”
In order to curb the toxic pollution threatening waterways like the Chesapeake Bay, the Colorado River and Puget Sound, Environment America recommends the following:
- Pollution Prevention: Industrial facilities should reduce their toxic discharges to waterways by switching from hazardous chemicals to safer alternatives.
- Protect all waters: The Obama administration should finalize guidelines and conduct a rulemaking to clarify that the Clean Water Act applies to all of our waterways – including the 2.5 million miles of streams in and 117 million Americans’ drinking water for which jurisdiction under the Clean Water Act has been called into question as a result of two polluter-driven Supreme Court decisions in the last decade.
- Tough permitting and enforcement: EPA and state agencies should issue permits with tough, numeric limits for each type of toxic pollution discharged, ratchet down those limits over time, and enforce those limits with credible penalties, not just warning letters.
“The bottom line is that America’s waterways shouldn’t be a polluter’s paradise, they should just be paradise. We need clean water now, and we are counting on the federal government to act to protect our health and our environment,” concluded Vinyard.

By Philip Fearnside / National Institute for Research in the Amazon
Brazil’s Belo Monte Dam on the Xingu River is now under construction despite its many controversies. The Brazilian government has launched an unprecedented drive to dam the Amazon’s tributaries, and Belo Monte is the spearhead for its efforts. Brazil’s 2011-2020 energy-expansion plan calls for building 48 additional large dams, of which 30 would be in the country’s Legal Amazon region. Building 30 dams in 10 years means an average rate of one dam every four months in Brazilian Amazonia through 2020. Of course, the clock doesn’t stop in 2020, and the total number of planned dams in Brazilian Amazonia exceeds 60.
The Belo Monte Dam itself has substantial impacts. It is unusual in not having its main powerhouse located at the foot of the dam, where it would allow the water emerging from the turbines to continue flowing in the river below the dam. Instead, most of the river’s flow will be detoured from the main reservoir through a series of canals interlinking five dammed tributary streams, leaving the “Big Bend” of the Xingu River below the dam with only a tiny fraction of its normal annual flow.
What is known as the “dry stretch” of 100 km between the dam and the main powerhouse includes two indigenous reserves, plus a population of traditional Amazonian riverside dwellers. Since the impact on these people is not the normal one of being flooded by a reservoir, they were not classified as “directly impacted” in the environmental study and have not had the consultations and compensations to which directly impacted people are entitled. The human rights commission of the Organization of American States (OAS) considered the lack of consultation with the indigenous people a violation of the international accords to which Brazil is a signatory, and Brazil retaliated by cutting off its dues payments to the OAS. The dam will also have more familiar impacts by flooding about one fourth of the city of Altamira, as well as the populated rural areas that will be flooded by the reservoir.What is most extraordinary is the project’s potential impact on vast areas of indigenous land and tropical rainforest upstream of the reservoir, but the environmental impact studies and licensing have been conducted in such a way as to avoid any consideration of these impacts. The original plan for the Xingu River called for five additional dams upstream of Belo Monte. These dams, especially the 6,140 square kilometer Babaquara Dam (now renamed the “Altamira” Dam), would store water that could be released during the Xingu River’s low-flow period to keep the turbines at Belo Monte running.The Xingu has a large annual oscillation in water flow, with as much as 60 times more water in the high-flow as compared to the low-flow period. During the low-flow period the unregulated flow of the river is insufficient to turn even one of the turbines in Belo Monte’s 11,000 MW main powerhouse. Since the Belo Monte Dam itself will be essentially ‘run-of-the-river’, without storing water in its relatively small reservoir, economic analysis suggests that the dam by itself won’t be economically viable.
The official scenario for the Xingu River changed in July 2008 when Brazil’s National Council for Energy Policy (CNPE) declared that Belo Monte would be the only dam on the Xingu River. However, the council is free to reverse this decision at any time. Top electrical officials considered the CNPE decision a political move that is technically irrational. Brazil’s current president blocked creation of an extractive reserve upstream of Belo Monte on the grounds that it would hamper building “dams in addition to Belo Monte”. The fact that the Brazilian government and various companies are willing to invest large sums in Belo Monte may be an indication that they do not expect history to follow the official scenario of only one dam.
In addition to their impacts on tropical forests and indigenous peoples, these dams would make the Xingu a source of greenhouse-gas emissions, especially methane (CH4) which forms when dead plants decay on the bottom of a reservoir where the water contains no oxygen. The Babaquara Dam’s 23m vertical variation in water level, annually exposing and flooding a 3,580 square kilometer drawdown zone would make the complex a virtual ‘methane factory’. The reservoir’s flooding of soft vegetation growing in the drawdown zone converts carbon from CO2 removed from the atmosphere by photosynthesis into CH4, with a much higher impact on global warming.
