Brazilian firm's mega-dam plans in Peru spark major social conflict
(05/11/2015) 'I don't want to sell my land because I've lived here since I was 17,' declared 82 year old María Araujo Silva. 'This was where my children were born. I want to die here. That's why I'm not in agreement. I'm not in agreement with the dam.' Araujo Silva is outraged at plans by Peru's government and Brazilian company Odebrecht to build a hydroelectric dam just downriver from her village, Huarac, on the Marañón River.
Activist deported from Cambodia continues fighting dam from abroad
(05/06/2015) Alex Gonzalez-Davidson has been campaigning to prevent construction of a proposed dam on the Areng River in the Cardamom Mountains. The Cambodian government deported him in February, but evidence is mounting that the dam project may have stalled.
Peru's mega-dam projects threaten Amazon River source and ecosystem collapse
(04/28/2015) Peru is planning a series of huge hydroelectric dams on the 1,700-kilometer (1,056-mile) Marañón River, which begins in the Peruvian Andes and is the main source of the Amazon River. Critics say the mega-dam projects could destroy the currently free-flowing Marañón, resulting in what Peruvian engineer Jose Serra Vega calls its 'biological death'.
Conservation in Myanmar: a cause for optimism?
(04/24/2015) Fifty years of relative political and economic isolation have yielded slow economic growth and contributed to the conservation of many of Myanmar’s native species. However, the dissolution of Myanmar’s military junta in 2011 marked the beginning of a new age of increasing political and economic liberalization and international engagement. Many experts fear that possible rapid development fueled by international investment, improved infrastructure and expanded transport networks, pose a grave risk to Myanmar’s biodiversity and forests.
Featured video: 'A river in dispute' documentary explores how a planned dam in the Amazon is affecting traditional communities
(04/15/2015) Under the threat of losing their lands to a hydroelectric power plant project strategic to the Brazilian government, communities along the Tapajós River, one of the most pristine in Brazil, prepare to defend what is theirs. A video documentary tells their story.
9 months after Amazonian oil pipeline spill, effects and fears linger
(03/30/2015) When Peru's state-run oil company pulled out of this small Kukama Indian village in mid-December after cleaning up an oil pipeline spill, residents thought life could slowly return to normal. But more than three months later, wisps of oil floating down the Cuninico River—along with a larger spill in the neighboring community of San Pedro—are a reminder that the problems are not over.
Conservationists catch-and-release record-smashing freshwater fish
(03/17/2015) Conservationists and scientists have managed to catch-and-release what could be the world's biggest freshwater fish ever for an upcoming episode of Ocean Mysteries.

Photo essay: filming in the remote Amazon
(03/09/2015) You wake up at 4:30 AM, a little before the first rays of tropical sun begin to dance behind the treetops. You put on your wet clothes from the previous day, pack your bag, and pick up your tripod. The jungle is shrouded in a thick mist from the previous nights rain. As you walk, you recognize many of the strange calls that echo between the trees.
Amazon gold rush destroying huge swaths of rainforest
(01/14/2015) The rainforests of South America face many threats. The deforestation occurring on the continent is among the highest in the world and results in losses of habitat, biodiversity and massive amounts of sequestered carbon. While the usual culprits such as farming, ranching and logging are well known, gold mining is fast extending its destructive reach into some of the world’s most untouched landscapes, according to new research.
Endangered mussel still harvested for food in Laos
(12/29/2014) Only one freshwater pearl mussel species is known to inhabit tropical water systems. However, despite being listed as Endangered by the IUCN, it is also still a part of the diet of villagers in Northern Laos. A study published recently found that the dwindling populations of the bivalve would benefit from a ban on their capture.
Impacts of deforestation on Amazonian river ecosystems could be far-reaching
(12/18/2014) A study by researchers in Brazil published this week has found that deforestation in the Southern Amazon may impair significantly the structure and function of rivers, and make them less able to support life.

Old fishermen document declining range of the Indus River dolphin
(12/03/2014) The Indus River dolphin (Platanista gangetica minor) is an endangered freshwater mammal found only in the Indus River and tributaries draining the Himalayas. Since 1879, the dolphin—locally known as the bhulan—has vanished from 80 percent of its range. Now, a study using interviews with dozens of elders in the Pakistani fishing communities along the river documents when dolphins disappeared from different river sections.
Egyptian art helps chart past extinctions of big mammals
(12/01/2014) Life in modern Egypt clings to the Nile River. This crowded green strip within the desert supports more than 2,300 people per square kilometer (6,000 per square mile). But 6,000 years ago, all of Egypt was green and vibrant, teeming with life much like the current Serengeti. Over time, this rich ecosystem fell apart.
Man plants forest, becomes film star
(11/14/2014) Jadav “Molai” Payeng is a 51-year-old man who lives in India’s north-eastern state of Assam in the village of Aruna Chapori.

'River wolves' recover in Peruvian park, but still remain threatened inside and out (photos)
(10/14/2014) Lobo de río, or river wolf, is the very evocative Spanish name for one of the Amazon's most spectacular mammals: the giant river otter. This highly intelligent, deeply social, and simply charming freshwater predator almost vanished entirely due to a relentless fur trade in the 20th Century. But decades after the trade in giant river otter pelts was outlawed, the species is making a comeback.
Oil palm, mining prompts local govt in Borneo to declare water unsafe for drinking
(08/06/2014) The Environment Ministry of Sintang Regency, West Kalimantan, Indonesia declared that the water in many rivers and lakes is unsuitable for consumption due to high levels of pollution.
DRC deforestation escalates despite resource shortages, protests, rape, homicide
(07/10/2014) Road construction, the promise of employment, and the conversion of forest to farmland – the effects of logging tropical forests are often not confined to the boundaries of the concessions, where, in the best case, a timber company has gained legal access to harvest trees. Along the Congo River in the northern Democratic Republic of Congo, recent data showing probable forest loss demonstrate the often-unforeseen consequences of timber harvesting.
An end to India's 'Wild West'? Meghalaya bans coal mining... for now
(07/08/2014) Meghalaya, a state in India’s northeast, has thick forests above ground and valuable minerals below. Uncontrolled mining in the area has cleared forests, degraded rivers, and led to many accidents and deaths as few health and safety standards exist for mine workers. A ban effected earlier this year halted all mining in the state, but is set to be reconsidered at a hearing scheduled for August.
Oil palm plantations degrade local water quality relative to community forests
(06/30/2014) Oil palm plantations are not only encroaching on forests, they are also degrading water quality, finds a new study published in the Journal of Geophysical Research: Biogeosciences.
Broken promises no more? Signs Sabah may finally uphold commitment on wildlife corridors
(06/23/2014) Five years ago an unlikely meeting was held in the Malaysian state of Sabah to discuss how to save wildlife amid worsening forest fragmentation. Although the meeting brought together longtime adversaries—conservationists and the palm oil industry—it appeared at the time to build new relationships and even point toward a way forward for Sabah's embattled forests.
Oil drilling causes widespread contamination in the Amazon rainforest
(06/13/2014) Decades of oil extraction in the Western Amazon has caused widespread pollution, raising questions about the impact of a new oil boom in the region, according to a team of Spanish researchers presenting at a conference in California.
Chile drops hugely controversial mega-dam project in wild Patagonia
(06/12/2014) One of the world's most controversial mega-dam projects met its likely end this week when Chile's Committee of Ministers voted to cancel the permits for the HidroAysén project. Costing around $8 billion and expected to produce about 2.75 gigawatts, the project involved building five large dams on two wild rivers in Chile's famously-unspoiled Patagonia region.
Dams be damned: study finds large dams are too expensive
(05/19/2014) Hydroelectric power, supplied mostly from dams, provides approximately 20 percent of the world's electricity, an amount of energy equivalent to 3.6 billion barrels of oil. However, a recent study by researchers at Oxford University has found that large dams cost so much money and take so long to build that they may not be economically viable.
Scientists release odd-looking, Critically Endangered crocodiles back into the wild (PHOTOS)
(05/13/2014) Among the largest and most endangered crocodilians in the world, the gharial is on the verge of extinction today. This harmless fish-eating crocodile has fewer than 200 adult breeding individuals in the wild, their numbers having plummeted rapidly over the past few decades. But among this gloom and doom, conservationists have been working tirelessly to reinstate the wild populations.
Fish-terrorizing, prehistoric-looking turtle actually three species
(04/30/2014) So, you're a fish swimming in a river in Louisiana. Hungry, you see a little worm wiggling out from the river bed. You swoop in for the ambush only to have that little worm turn into the gaping maw of some prehistoric-looking monster out of fishy nightmares. You've been duped: it's too late to escape as the beast's jagged jaws close over you. Meet the alligator snapping turtle...or one of several species.
Controversial Amazon dams may have exacerbated biblical flooding
(03/16/2014) Environmentalists and scientists raised howls of protest when the Santo Antônio and Jirau Dams were proposed for the Western Amazon in Brazil, claiming among other issues that the dams would raise water levels on the Madeira River, potentially leading to catastrophic flooding. It turns out they may have been right: last week a federal Brazilian court ordered a new environmental impact study on the dams given suspicion that they have worsened recent flooding in Brazil and across the border in Bolivia.
Nicaragua Canal could cause ecological disaster, warn experts
(02/20/2014) Nicaragua's plans for a canal linking the Pacific and Atlantic Oceans could trigger an environmental disaster through habitat destruction and alteration, introduction of non-native species, pollution, and sedimentation, warns a commentary published in this week's issue of Nature.
New dolphin discovered in the Amazon surprises scientists
(01/23/2014) Researchers have discovered a new species of river dolphin from the Amazon.

It is the first true river dolphin discovered since 1918.
Pet fish invade ecosystem, upending nutrients and impoverishing fishers
(10/02/2013) If you, or someone you know, owns a freshwater aquarium, chances are you have seen the peculiar little creature attached face-first to the glass in effort to find a morsel of algae. This algae eater, popularly known as the sucker fish, is the sailfin catfish, or plecos. It is one of the most commonly purchased fish in the freshwater aquarium fish trade, and, according to recent research in The Royal Society B, aquarists often reintroduce the sucker-fish into the wild with detrimental consequences.
Judge halts construction of Amazon dam on Brazil's Teles Pires river
(09/19/2013) A federal judge in Brazil has ordered the suspension of construction activities on the Teles Pires due to shortcomings in the environmental licensing process, including the project's impacts on three local tribes, reports International Rivers.
Forgotten species: the arapaima or 'dinosaur fish'
(07/15/2013) Let's go back some 14,000 years (or up to 50,000 depending on who you talk to), since this is the first time humans encountered the meandering, seemingly endless river system of the Amazon. Certainly, the world's first Amazonians would have been astounded by the giant beasts of the region, including ground sloths and mastodons (both now extinct), as well as giant anteaters, armadillos, and tapirs, currently the biggest land animal on the continent. But these first explorers might have been even more surprised by what dwelled in the rivers: anaconda, caiman, and the arapaima. Wait, the what?
Stand up paddleboarding in the Amazon for conservation
(07/09/2013) This week an international team is setting off on a unique journey, aiming to be the first to descend the Amazon River using inflatable Stand Up Paddle boards. The group, led by Dr. Mika Peck, a conservation biologist from the University of Sussex with years of work in Ecuador and Colombia, includes Brazilian and Colombian researchers as well as an indigenous community leader.
Yangtze finless porpoise drops to Critically Endangered
(07/07/2013) The newest update to the IUCN Red List has downgraded the status of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) from Endangered to Critically Endangered, reflecting the deteriorating state of arguably the world's most degraded river system. The downgrade follows a survey last year that counted only 1,000 animals, a 50 percent decline from 2006.
Pesticides decimating dragonflies and other aquatic insects
(06/18/2013) While recent research (and media attention) has focused on the alleged negative impacts of pesticides on bees, the problem may be far broader according to a new study in the Proceedings of the US Academy of Sciences (PNAS). Looking at over 50 streams in Germany, France, and Australia, scientists in Europe and Australia found that pesticide contamination was capable of undercutting invertebrate biodiversity by nearly half.
11,000 barrels of oil spill into the Coca River in the Amazon
(06/12/2013) On May 31st, a landslide ruptured an oil pipeline in Ecuadorean Amazon, sending around 11,000 barrels of oil ( 420,000 gallons) into the Coca River. The oil pollution has since moved into the larger Napo River, which borders Yasuni National Park, and is currently heading downstream into Peru and Brazil. The spill has occurred in a region that is notorious for heavy oil production and decades of contamination, in addition to resistance and lawsuits by indigenous groups.
Conserving the long-neglected freshwater fish of Borneo
(06/11/2013) Borneo is a vast tropical island known for orangutans, rhinos, elephants, sun bears, proboscis monkeys, hornbills, and ubiquitous leeches. Conservationists have championed all of these species (aside from the leeches) in one way or another, but like many tropical regions Borneo's freshwater species have long been neglected, despite their rich biodiversity and importance to local people. But a new organization, the Kinabatangan River Spirit Initiative, is working to change that.
China to build $17B worth of dams in Indonesian Borneo
(06/09/2013) Two Chinese companies — China Power Investment Corporation and Anhui Conch Cement — will invest $17 billion in dams in North Kalimantan, Indonesia's newest province located on the island of Borneo, reports the Jakarta Globe.
Scientists discover high mercury levels in Amazon residents, gold-mining to blame
(05/28/2013) The Madre de Dios region in Peru is recognized for its lush Amazon rainforests, meandering rivers and rich wildlife. But the region is also known for its artisanal gold mining, which employs the use of a harmful neurotoxin. Mercury is burned to extract the pure gold from metal and ore producing dangerous air-borne vapors that ultimately settle in nearby rivers. 'Mercury in all forms is a potent neurotoxin affecting the brain, central nervous system and major organs,'Luis Fernandez, an ecologist and research associate at the Carnegie Institution's Department of Global Ecology, told mongabay.com. 'At extremely high exposure levels, mercury has been documented to cause paralysis, insanity, coma and death.'
Water crisis widening: 4.5 billion people live near 'impaired water sources'
(05/28/2013) The majority of the 9 billion people on Earth will live with severe pressure on fresh water within the space of two generations as climate change, pollution and over-use of resources take their toll, 500 scientists have warned.
Mystery of Amazon River carbon emissions solved
(05/21/2013) Bacteria living in the Amazon River digest nearly all wood plant matter that enters the river before it reaches the Atlantic Ocean, triggering the release of carbon locked up in the vegetation instead of sequestering it in the deep ocean, finds a new study published in Nature Geoscience. The research explains the mechanism by which the world's largest river 'exhales' large amounts of CO2.
China approves another mega-dam that will imperil endangered species
(05/21/2013) Chinese environmental authorities have approved construction plans for what could become the world's tallest dam, while acknowledging that the project would affect endangered plants and rare fish species.
Amazon's flood/drought cycle becoming more extreme, less predictable
(05/14/2013) The Amazon River's hydrological cycle has become more extreme over the past two decades with increasing seasonal precipitation across much of the basin despite drier conditions in the southern parts of Earth's largest rainforest, finds a new study published in Geophysical Research Letters. The research analyzed monthly Amazon River discharge at Óbidos, a point that drains 77 percent of the Amazon Basin, and compared it with regional precipitation patterns.
Rainforest tribe urges Norwegian king to recall energy executive
(05/13/2013) In an unusual bid to stop a series of dams that will flood their rainforest home, a group of tribesmen in Borneo are urging King Harald V of Norway to call one of his subjects home. The subject is Torstein Dale Sjøtveit, a Norwegian citizen who is the CEO of Sarawak Energy, a Malaysian firm that is building several dams in the state of Sarawak. The hydroelectric projects are controversial because they require the forced displacement of indigenous communities and will flood large tracts of rainforest.
Deforestation will undercut effectiveness of rainforest dams
(05/13/2013) Deforestation may significantly decrease the hydroelectric potential of tropical rainforest regions, warns a new study published in Proceedings of the National Academy of Science. The study, used climate, hydrological, and land use models to forecast the impact of potential forest loss on hydropower generation on the Xingu River, a major tributary of the Amazon where the world's third largest dam — Belo Monte — is currently under construction.
New endangered list for ecosystems modeled after 'Red list' for species
(05/09/2013) The IUCN has unveiled the first iteration of its new Red List of Ecosystems, a ranking of habitats worldwide.
Uranium mine at edge of Grand Canyon National Park approved
(05/08/2013) Uranium mining on the doorstep of the Grand Canyon national park is set to go ahead in 2015 despite a ban imposed last year by Barack Obama. Energy Fuels Resources has been given federal approval to reopen its old Canyon Mine, located six miles south of the canyon's popular South Rim entrance, that attracts nearly 5 million visitors a year.
Tribesmen launch 'occupy' protest at dam site in the Amazon rainforest
(05/03/2013) On Thursday roughly 200 indigenous people launched an occupation of a key construction site for the controversial Belo Monte dam in the Brazilian Amazon. The protestors, who represent communities that will be affected by the massive dam, are demanding immediate suspension of all work on hydroelectric projects on the Xingu, Tapajós and Teles Pires rivers until they are properly consulted, according to a coalition of environmental groups opposing the projects.
Mekong region has lost a third of its forests in 30 years, may lose another third by 2030
(05/03/2013) The Greater Mekong region of Cambodia, Laos, Myanmar (Burma), Thailand and Vietnam will lose a third of its remaining forest cover by 2030 unless regional governments improve management of natural resources and transition toward a greener growth model, warns a new report issued by WWF.
Indigenous tribes say effects of climate change already felt in Amazon rainforest
(04/30/2013) Tribal groups in Earth's largest rainforest are already being affected by shifts wrought by climate change, reports a paper published last week in the British journal Philosophical Transactions of the Royal Society B. The paper, which is based on a collection of interviews conducted with indigenous leaders in the Brazilian Amazon, says that native populations are reporting shifts in precipitation patterns, humidity, river levels, temperature, and fire and agricultural cycles. These shifts, measured against celestial timing used by indigenous groups, are affecting traditional ways of life that date back thousands of years.
Featured documentary: Damocracy, highlighting the battles over the Belo Monte and Ilisu dams
(04/29/2013) A new short documentary highlights the battles over monster dam projects imperiling local people and wild rivers. Examining the Belo Monte dam in Brazil and the Ilisu dam in Turkey, the documentary argues that such hydroelectric projects cannot be deemed "green" energy as they overturn lives, livelihoods, and ecosystems.
The river of plenty: uncovering the secrets of the amazing Mekong
(04/23/2013) Home to giant catfish and stingrays, feeding over 60 million people, and with the largest abundance of freshwater fish in the world, the Mekong River, and its numerous tributaries, brings food, culture, and life to much of Southeast Asia. Despite this, little is known about the biodiversity and ecosystems of the Mekong, which is second only to the Amazon in terms of freshwater biodiversity. Meanwhile, the river is facing an existential crisis in the form of 77 proposed dams, while population growth, pollution, and development further imperil this understudied, but vast, ecosystem.
Judge halts military-backed dam assessment in Brazil's Amazon
(04/17/2013) A federal court in Brazil has suspended the use of military and police personnel during technical research on the controversial São Luíz do Tapajós Dam in the Brazilian Amazon. The military and police were brought in to stamp down protests from indigenous people living along the Tapajós River, but the judge decreed that impacted indigenous groups must give free, prior, and informed consent (FPIC) before any furter studies can be done on the proposed dam. However, the decision is expected to be appealed.
Yangtze porpoise down to 1,000 animals as world's most degraded river may soon claim another extinction
(04/16/2013) A survey late last year found that the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) population has been cut in half in just six years. During a 44-day survey, experts estimated 1,000 river porpoises inhabited the river and adjoining lakes, down from around 2,000 in 2006. The ecology of China's Yangtze River has been decimated the Three Gorges Dam, ship traffic, pollution, electrofishing, and overfishing, making it arguably the world's most degraded major river. These environmental tolls have already led to the likely extinction of the Yangtze river dolphin (Lipotes vexillifer), or baiji, and possibly the Chinese paddlefish (Psephurus gladius), which is one of the world's longest freshwater fish.
Indigenous group: Brazil using military to force Amazon dams
(04/08/2013) An Amazonian community has threatened to "go to war" with the Brazilian government after what they say is a military incursion into their land by dam builders. The Munduruku indigenous group in Para state say they have been betrayed by the authorities, who are pushing ahead with plans to build a cascade of hydropower plants on the Tapajós river without their permission.
After decades of turning a blind eye, Peru declares state of emergency due to oil contamination in Amazon
(03/26/2013) The Peruvian government has declared an environmental state of emergency after finding elevated levels of lead, barium, and chromium in the Pastaza River in the Amazon jungle, reports the Associated Press. Indigenous peoples in the area have been complaining for decades of widespread contamination from oil drilling, but this is the first time the Peruvian government has acknowledged their concerns. Currently 84 percent of the Peruvian Amazon is covered by potential oil blocs, leading to conflict with indigenous people and environmental degradation.
Jaguars, tapirs, oh my!: Amazon explorer films shocking wildlife bonanza in threatened forest
(02/19/2013) Watching a new video by Amazon explorer, Paul Rosolie, one feels transported into a hidden world of stalking jaguars, heavyweight tapirs, and daylight-wandering giant armadillos. This is the Amazon as one imagines it as a child: still full of wild things. In just four weeks at a single colpa (or clay lick where mammals and birds gather) on the lower Las Piedras River, Rosolie and his team captured 30 Amazonian species on video, including seven imperiled species. However, the very spot Rosolie and his team filmed is under threat: the lower Las Piedras River is being infiltrated by loggers, miners, and farmers following the construction of the Trans-Amazon highway.
Brazilian agency rejects Canadian company's bid to mine controversial Amazon dam site for gold
(02/13/2013) Brazil's Federal Public Ministry rejected a proposed gold mining project adjacent to a controversial dam site in the heart of the Amazon rainforest, reports Amazon Watch, an environmental activist group that is campaigning against both the mine and the dam.
Amazon river ecosystems being rapidly degraded, but remain neglected by conservation efforts
(02/08/2013) The world's largest river system is being rapidly degraded and imperiled by dams, mining, overfishing, and deforestation, warns a study published last week by an international team of scientists.
Fish unable to pass through dams in U.S. presents 'cautionary tale' for developing world
(01/17/2013) Dams create a largely impenetrable barrier for fish even when the dams were installed with specially-built passages, according to a new study in Conservation Letters. The scientists found that migrating fish largely failed to use the passages in the U.S., resulting in far fewer moving through the state-of-the-art hydroelectric dams than had been promised. The researchers say that their findings are a "cautionary tale" for developing nations.
Gold mine approved in French Guiana's only national park
(01/15/2013) Tensions have risen in the small Amazonian community of Saül in French Guiana after locals discovered that the French government approved a large-scale gold mining operation near their town—and inside French Guiana's only national park—against their wishes. Run by mining company, Rexma, locals and scientists both fear that the mine would lead to deforestation, water pollution, and a loss in biodiversity for a community dependent on the forest and ecotourism.
Environment ministry drops copper mine in Zambezi park
(01/07/2013) A proposed copper mine set to be built in Lower Zambezi National Park has been rejected by Zambia's environmental management agency. Australian company Zambezi Resources Ltd, a subsidiary of Proactive Investors, had scheduled the $494 million Kangaluwi Copper Project to begin production in 2015. But their proposal sparked an outcry from environmentalists and government lobbyists concerned about the effects of the open pit mine in the park. Though mining is not generally permitted in the park, Zambezi Resources obtained a Large-Scale Mining License from the government which would have allowed them to mine for 25 years right in the middle of Lower Zambezi National Park.
China plans over 300 dam projects worldwide
(12/10/2012) A new report by the NGO, International Rivers, takes an in-depth look at the role China is playing in building mega-dams worldwide. According to the report, Chinese companies are involved in 308 hydroelectric projects across 70 nations. While dams are often billed as "green energy," they can have massive ecological impacts on rivers, raise local conflict, and even expel significant levels of greenhouse gases when built in the tropics.
Dams are rapidly damning the Amazon
(12/08/2012) Dam-builders seeking to unlock the hydroelectric potential of the Amazon are putting the world's mightiest river and rainforest at risk, suggests a new assessment that charts the rapid expansion of dams in the region.
Forests, farming, and sprawl: the struggle over land in an Amazonian metropolis
(12/04/2012) The city of Parauapebas, Brazil is booming: built over the remains of the Amazon rainforest, the metropolis has grown 75-fold in less than 25 years, from 2,000 people upwards of 150,000. But little time for urban planning and both a spatial and mental distance from the federal government has created a frontier town where small-scale farmers struggle to survive against racing sprawl, legal and illegal mining, and a lack of investment in environmental protection. Forests, biodiversity, and subsistence farmers have all suffered under the battle for land. In this, Parauapebas may represent a microcosm both of Brazil's ongoing problems (social inequality, environmental degradation, and deforestation) and opportunity (poverty alleviation, reforestation, and environmental enforcement).
Brazilian bank approves $10.8 billion loan for controversial Amazon rainforest dam
(11/30/2012) Brazil's National Development Bank (BNDES) on Monday announced it has approved a $10.8 billion (22.5 billion Brazilian reais) loan to the consortium that is building the controversial Belo Monte dam in the state of Par´ in the heart of the Amazon rainforest, reports International Rivers, a group that is campaigning against the dam. The loan in the largest in the bank's 60-year history, according to the group.
Introducing the 'Obama-fish'

Controversial dam gets approval in Laos
(11/07/2012) Laos has given approval to the hugely-controversial $3.5 billion Xayaburi Dam on the Mekong River, reports the BBC. The massive dam, which would provide 95 percent of its energy production to Thailand, has been criticized for anticipated impacts on the river's fish populations, on which many locals depend.
Artificial 'misting system' allows vanished toad to be released back into the wild
(11/01/2012) In 1996 scientists discovered a new species of dwarf toad: the Kihansi spray toad (Nectophrynoides asperginis). Although surviving on only two hectares near the Kihansi Gorge in Tanzania, the toads proved populous: around 17,000 individuals crowded the smallest known habitat of any vertebrate, living happily off the moist micro-habitat created by spray from adjacent waterfalls. Eight years later and the Kihansi spray toad was gone. Disease combined with the construction of a hydroelectric dam ended the toads' limited, but fecund, reign.
Future of the Tongass forest lies in salmon, not clear-cut logging
(10/25/2012) The Parnell administration's Timber Task Force recently unveiled a proposal to carve out two million acres of the Tongass National Forest for clear-cut logging under a state-managed "logging trust." The stated goal is to revive Southeast Alaska’s timber industry that collapsed two decades ago amid changing market conditions, logging cutbacks and evolving public opinion about timber harvesting on national forests.
El Salvador mulls total ban on mining
(10/22/2012) On hot days the broken stone and dried up silt from the San Sebastian mine in Eastern El Salvador bake in the sun. The slew of refuse is freckled with rock stained bright blue with cyanide, open to the elements that on rainier days will wash it downhill into the Rio San Sebastian below. The openings of passages into the mine dot the mountainside, and further downhill a bright orange stream with a chemical stench flows into another. The American Commerce Group ceased operating here in 1999 but sought to return when the price of gold began its current escalation.
Indigenous groups re-occupy Belo Monte dam in the Amazon
(10/09/2012) Construction on Brazil's megadam, Belo Monte, has been halted again as around 150 demonstrators, most of them from nearby indigenous tribes, have occupied the main construction site at Pimental. Over a hundred indigenous people joined local fishermen who had been protesting the dam for 24 days straight. Indigenous people and local fishermen say the dam will devastate the Xingu River, upending their way of life.

Belo Monte mega-dam halted again by high Brazilian court, appeal likely but difficult
(08/15/2012) A high federal court in Brazil has ruled that work on the Belo Monte dam in the Brazilian Amazon be immediately suspended. Finding that the government failed to properly consult indigenous people on the dam, the ruling is the latest in innumerable twists and turns regarding the massive dam, which was first conceived in the 1970s, and has been widely criticized for its impact on tribal groups in the region and the Amazon environment. In addition the Regional Federal Tribunal (TRF1) found that Brazil's Environmental Impact Assessment was flawed since it was conducted after work on the dam had already begun.

Exploring Asia's lost world
(05/03/2012) Abandoned by NGOs and the World Bank, carved out for rubber plantations and mining by the Cambodian government, spiraling into a chaos of poaching and illegal logging, and full of endangered species and never-explored places, Virachey National Park may be the world's greatest park that has been written off by the international community. But a new book by explorer and PhD student, Greg McCann, hopes to change that. Entitled Called Away by a Mountain Spirit: Journey to the Green Corridor, the book highlights expeditions by McCann into parts of Virachey that have rarely been seen by outsiders and have never been explored scientifically, including rare grasslands that once housed herds of Asian elephants, guar, and Sambar deer, before poachers drove them into hiding, and faraway mountains with rumors of tigers and mainland Javan rhinos.

Pictures: Destruction of the Amazon's Xingu River begins for Belo Monte Dam
(04/18/2012) The Xingu River will never be the same. Construction of Belo Monte Dam has begun in the Brazilian Amazon, as shown by these photos taken by Greenpeace, some of the first images of the hugely controversial project. Indigenous groups have opposed the dam vigorously for decades, fearing that it will upend their way of life. Environmentalists warn that the impacts of the dam—deforestation, methane emissions, and an irreparable changes to the Xingu River's ecosystem—far outweigh any benefits. The dam, which would be the world's third largest, is expected to displace 16,000 people according to the government, though some NGOs put the number at 40,000. The dam will flood over 40,000 hectares of pristine rainforest, an area nearly seven times the size of Manhattan.

However, the mega-dam proposal has been heavily criticized for its impact on Sarawak's rivers, rainforest and indigenous people.
Indigenous groups fight for recognition and illumination in Peru
(03/26/2012) "Shh, wait here," Wilson told me. I ducked down behind the buttress of a large tree to wait. We had been walking through the jungle for a few hours. At first we followed a path through the undergrowth, a wet world of ferns, trunks and lianas speckled with the sunlight that made it down through the canopy and understory, but soon we simply walked along a route Wilson picked out. I had been trying to concentrate on the myriad sounds: cicadas were the background and various small birds tweeted from different points. We were listening and looking for signs that would lead us to prey—perhaps the calm whistle of a perdiz or the scent—marking of a boar—but just before Wilson became excited I had heard nothing. He stopped and said, "Red monkeys," pointing ahead.
Belo Monte Dam: A spearhead for Brazil’s dam-building attack on the Amazon?
(03/23/2012) 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 region1. 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.
