An undamaged Amazon produces its own clouds and rain
(09/21/2010) Researchers recently traveled to the remote Brazilian Amazon to investigate how clouds are formed and rain falls in an atmosphere unburdened by human-caused pollution. Studying the atmospheric aerosol particles, which impact cloud formation and particles, above a pristine forests, researchers discovered that when left alone the Amazon acts as its own 'bioreactor': clouds and precipitation are produced by the abundance of plant materials.
How the overlooked peccary engineers the Amazon, an interview with Harald Beck
(09/20/2010) When people think of the Amazon rainforest, they likely think of roaring jaguars, jumping monkeys, marching ants, and squeezing anacondas. The humble peccary would hardly be among the first animals to cross their mind, if they even know such pig-like animals exists! Yet new research on the peccary is proving just how vital these species are to the world's greatest rainforest. As seed dispersers and seed destroyers, engineers of freshwater habitats and forest gaps, peccaries play an immense, long overlooked, role in the rainforest. "Peccaries have the highest density and biomass of any Neotropical mammal species. Obviously these fellows have quite an appetite for almost anything, but primarily they consume fruits and seeds. Their specialized jaws allow them to crush very hard seeds. The cracking sounds can be heard through the thick vegetation long before we could see them. As peccary herds bulldoze through the leaf litter in search for insects, frogs, seeds, and fruits, they destroy (i.e. snap and trample) many seedlings and saplings, sometimes leaving only the bare ground behind," Harald Beck, assistant professor at Towson University in Maryland, told mongabay.com in an interview.
Brazil's cerrado wins protection, but will it be enough to save the wildlife-rich grassland?
(09/15/2010) Brazil announced a plan to protect the cerrado, the vast woody savanna that covers 20 percent of the country but has become the nation's biggest single source of carbon emissions due to conversion for agriculture and cattle pasture, reports Brazil's Ministry of the Environment.
Indigenous tribes, ranchers team to battle Amazon fires
(09/14/2010) Facing the worst outbreak of forest fires in three years, cattle ranchers and indigenous tribesmen in the southern Amazon have teamed up to extinguish nearly two dozen blazes over the past three months, offering hope that new alliances between long-time adversaries could help keep deforestation rates in the Brazilian Amazon on a downward trajectory.
A look at Ecuador's agreement to leave 846 million barrels of oil in the ground
(09/13/2010) Ecuador's pioneering initiative to voluntarily leave nearly a billion barrels of oil under Yasuní National Park, an Amazonian reserve that is arguably the most biodiverse spot on Earth, took a major step forward in early August when the government signed an accord with the United Nations Development Programme (UNDP) for the long-awaited establishment of a trust fund. The signing event generated a wave of international media attention, but there has been very little scrutiny of what was actually signed. Here we present an initial analysis of the signed agreement, along with a brief discussion of some of the potential caveats. Due to the precedent-setting nature of this agreement, attention to the details is now of the utmost importance.
Ecuador's tallest waterfall to be destroyed by Chinese dam
(09/07/2010) San Rafael Falls, Ecuador's tallest waterfall, is threatened by a Chinese-funded hydroelectric project, reports Save America's Forests, an environmental group.
Peru's rainforest highway triggers surge in deforestation, according to new 3D forest mapping
(09/06/2010) Scientists using a combination of satellite imagery, airborne-laser technology, and ground-based plot surveys to create three-dimensional high resolution carbon maps of the Amazon rainforest have documented a surge in emissions from deforestation and selective logging following the paving of the Trans-Oceanic Highway in Peru. The study, published this week in the early edition of the Proceedings of the National Academy of Sciences, reveals that selective logging and other forms of forest degradation in Peru account for nearly a third of emissions compared to deforestation alone.
80% of tropical agricultural expansion between 1980-2000 came at expense of forests
(09/02/2010) More than 80 percent of agricultural expansion in the tropics between 1980 and 2000 came at the expense of forests, reports research published last week in the early online edition of the Proceedings of the National Academy of Sciences (PNAS). The study, based on analysis satellite images collected by the United Nations Food and Agricultural Organization (FAO) and led by Holly Gibbs of Stanford University, found that 55 percent of new agricultural land came at the expense of intact forests, while 28 percent came from disturbed forests. Another six percent came from shrub lands.
NASA: surge in Amazon fires
(08/31/2010) The number of fire hotspots has surged in the Bolivian and Brazilian parts of the Amazon, reveals data and imagery from NASA.
Amazon deforestation falls significantly in 2010, according to preliminary data
(08/31/2010) Deforestation in the Brazilian Amazon is down significantly since last year, according to preliminary estimates released by Brazil's National Institute for Space Research (INPE) and Imazon, a Brazil-based NGO that tracks forest loss and degradation across the Amazon. Analysis of NASA MODIS data by Imazon found some 1,488 square kilometers of forest were cleared during the 12 months ended July 31, 2010, down 16 percent from the same period last year, when 1,766 square kilometers were deforested. Meanwhile analysis by INPE shows an even steeper drop from 4,375 square kilometers in August 2008 through July 2009 to 2,296 square kilometers in the current period, a decline of 48 percent. The discrepancy between INPE's and Imazon's estimates results from differences in how deforestation is tracked.
Cold snap may have killed millions of fish in Bolivia, poisoning rivers
(08/31/2010) Although the last few months have been some of the warmest worldwide on record, including 17 countries reaching or breaking all-time highs, temperatures have not been above average everywhere. Cold air from Antarctica has brought chilling temperatures to parts of South America, including Bolivia where millions of fish and thousands of caimans, turtles, and river dolphins have perished according to Nature Communications.
Jump in fires in Brazil becomes Twitter sensation
(08/27/2010) The number of fires burning in Brazil more than doubled since last year, sparking a Twitter sensation, with more than 120,000 users tweeting messages with the hashtag '#chegadequeimadas' about the fires in a 48 hour window.
146 dams threaten Amazon basin
(08/19/2010) Although developers and government often tout dams as environmentally-friendly energy sources, this is not always the case. Dams impact river flows, changing ecosystems indefinitely; they may flood large areas forcing people and wildlife to move; and in the tropics they can also become massive source of greenhouse gases due to emissions of methane. Despite these concerns, the Amazon basin—the world's largest tropical rainforest—is being seen as prime development for hydropower projects. Currently five nations—Brazil, Bolivia, Colombia, Ecuador, and Peru—are planning over 146 big dams in the Amazon Basin. Some of these dams would flood pristine rainforests, others threaten indigenous people, and all would change the Amazonian ecosystem. Now a new website, Dams in Amazonia, outlines the sites and impacts of these dams with an interactive map.
U.S. signs debt-for-nature swap with Brazil to protect forests
(08/13/2010) The United States will cut Brazil's debt payments by $21 million under a debt-for-nature that will protect the Latin American country's endangered Atlantic Rainforest (Mata Atlantica), Caatinga and Cerrado ecosystems.
Summer from hell: seventeen nations hit all-time heat records
(08/09/2010) The summer isn't over yet, but already seventeen nations have matched or beaten their all-time heat records. According to Jeff Masters' WunderBlog, Belarus, the Ukraine, Cyprus, Russia, Finland, Qatar, the Sudan, Saudi Arabia, Niger, Chad, Kuwait, Iraq, Pakistan, Colombia, Myanmar, Ascension Island, and the Solomon Islands have all equaled or broken their top temperature records this year. In addition, the hottest temperature ever recorded in Asia was taken in Pakistan at 128 degrees Fahrenheit (53 degrees Celsius); this incredible temperature still has to be reviewed by the World Meteorological Organization (WMO).
Colombian indigenous leader shot dead
(08/08/2010) Luis Alfredo Socarrás Pimienta, an indigenous leader with the Wayúu tribe, was murdered outside his home in Riohacha, Colombia on July 27th. A human rights activist and leader of several demonstrations against the abuse of indigenous people and for better living conditions, Socarrás Pimienta was thought to have been shot dead by a hitman who then fled the scene. Following the murder leaflets were given out citing the names of murderers’ next targets which included a dozen more members of the Wayúu tribes, according to Survival International.
Hunting threatens the other Amazon: where harpy eagles are common and jaguars easy to spot, an interview with Paul Rosolie
(08/05/2010) If you have been fortunate enough to visit the Amazon or any other great rainforest, you've probably been wowed by the multitude and diversity of life. However, you also likely quickly realized that the deep jungle is not quite what you may have imagined when you were a child: you don't watch as jaguars wrestle with giant anteaters or anacondas circle prey. Instead life in the Amazon is small: insects, birds, frogs. Even biologists will tell you that you can spend years in the Amazon and never see a single jaguar. Yet rainforest guide and modern day explorer Paul Rosolie says there is another Amazon, one so pristine and with such wild abundance that it seems impossible to imagine if not for Rosolie's stories, photos, and soon videos. This is an Amazon where the big animals—jaguars, tapir, anaconda, giant anteaters, and harpy eagles—are not only abundant but visible. Free from human impact and overhunting, these remote places—off the beaten path of tourists—are growing ever smaller and, according to Rosolie, are in danger of disappearing forever.
Bold rainforest idea makes good: Ecuador secures trust fund to save park from oil developers
(08/03/2010) In what may amount to a historic moment in the quest to save the world's rainforests and mitigate climate change, Ecuador and the United Nations Development Fund (UNDF) have created a trust fund to protect one of the world's most biodiverse rainforests from oil exploration and development. The fund will allow the international community to pay Ecuador to leave an estimated 850 million barrels of oil in Yasuni National Park in the ground instead of extracting it. This first-of-its-kind agreement, known as the Yasuni-ITT Initiative, will allow the rainforest protected area to remain pristine: preserving one of the most species-rich places on Earth, safeguarding the lives of indigenous people, and keeping an estimated 410 million tons of CO2 out of the atmosphere.
Oil devastates indigenous tribes from the Amazon to the Gulf
(07/27/2010) For the past few months, the mainstream media has focused on the environmental and technical dimensions of the Gulf mess. While that’s certainly important, reporters have ignored a crucial aspect of the BP spill: cultural extermination and the plight of indigenous peoples. Recently, the issue was highlighted when Louisiana Gulf residents in the town of Dulac received some unfamiliar visitors: Cofán Indians and others from the Amazon jungle. What could have prompted these indigenous peoples to travel so far from their native South America? Victims of the criminal oil industry, the Cofán are cultural survivors. Intent on helping others avoid their own unfortunate fate, the Indians shared their experiences and insights with members of the United Houma Nation who have been wondering how they will ever preserve their way of life in the face of BP’s oil spill.
Indigenous tribes occupy dam in Brazil, demand reparations
(07/27/2010) An indigenous group in Brazil has taken over a hydroelectric dam, which they state has polluted vital fishing grounds and destroyed sacred burial ground. They are demanding reparations for the damage done and that no more dams are built in the region without their prior consent.
Illegal logging declining worldwide, but still 'major problem'
(07/15/2010) A new report by the Chatham House finds that illegal logging in tropical forest nation is primarily on the decline, providing evidence that new laws and international efforts on the issue are having a positive impact. According to the report, the total global production of illegal timber has fallen by 22 percent since 2002. Yet the report also finds that nations—both producers and consumers—have a long way to go before illegal logging is an issue of the past.
Controversial changes to Brazilian forest law passes first barrier
(07/08/2010) An amendment to undermine protections in Brazil's 1965 forestry code has passed it first legislative barrier, reports the World Wide Fund for Nature-Brasil (WWF). Yesterday the amendment passed a special vote in the Congress's Special Committee on Forest Law Changes.
With 'psychological cunning' wild cat lures monkeys by mimicking their babies' calls
(07/08/2010) It sounds like something out of a fairy-tale: the big bad predator lures its gullible prey by mimicking a loved one: 'why grandma, what big teeth you have!' But in this case it's the shocking strategy of one little-known jungle feline. In 2005 researchers with the Wildlife Conservation Society (WCS) were watching a group of eight pied tamarins ( Saguinus bicolor), squirrel-sized monkeys, feeding on a ficus tree in the Reserva Florestal Adolpho Ducke in Brazil. They then heard the sound of tamarin babies, but were surprised to see that the sound was not coming from young tamarins, but a hungry margay (Leopardus wiedii), a small cat native to Central and South America, which was hidden from the tamarins.
Top officials busted in Amazon logging raids, but political patronage may set them free
(07/08/2010) After two years of investigations, the Brazilian Federal Police arrested some of the most important politicians and authorities for illegal logging in the Amazon. Code-named Operation Jurupari, the Brazilian Federal Police uncovered a massive illegal logging scheme that resulted in the arrests of over 90 people and caused an estimated $500 million in damage to the Amazon rainforest. Over 496 square kilometers (192 square miles), an area the size of California or Spain, were affected and an estimated 1.5 million cubic meters (642 million board feet) of timber was illegally extracted. While the investigation focused on activities in the state of Mato Grosso, which is located in the southern Amazon and is one of the most deforested regions largely due to clearing land for expanding soya farms, it touched numerous others, including São Paulo, Paraná, Rio Grande do Sul, Espirito Santo, Minas Gerais and Distrito Federal.
The changing nature of illegal logging - and illegal logging investigations - in Brazil's Amazon
(07/08/2010) Operation Jurupari followed on several previous Brazilian Federal Police investigations into SEMA, including: Operation Curupira I (June 2005); Curupira II (August 2005); Mapinguari (2007), Arc of Fire (2008), Termes (April 2008); and Caipora (2008). It was led by Franco Perazzoni, Brazilian Federal Police "Delegado" (or chief), who, since 2006, has headed the environmental crimes unit in Mato Grosso and been responsible for about 300 investigations on environmental crimes, of which about 75% were on illegal deforestation in federal areas. The nature of the illegal deforestation has changed over the years.
Amazon soy moratorium extended
(07/08/2010) Brazilian soy farmers have extended their moratorium on Amazon deforestation for another year, reports Greenpeace.
Spotted uncontacted native flees, leaving dinner and dish behind
(07/07/2010) The man had set up camp and was preparing to cook live turtles for a meal when he was seen by people he did not know. He hid behind a tree and then fled from the camp into the forest, abandoning his uncooked turtles and a clay pot behind.
Amazon and Atlantic Forest under threat: politicians press to dilute Brazil's forestry law
(07/01/2010) A group of Brazilian legislatures, known as the 'ruralistas', are working to change important aspects of the Brazil's landmark 1965 forestry code, undermining forest protection in the Amazon and the Mata Atlantica (also known as the Atlantic Forest) and perhaps heralding a new era of booming deforestation. The ruralistas, linked to big agribusiness and landowners, are taking aim at the part of the forestry code that requires landowners in the Amazon to retain 80 percent of their land area as legal reserves, arguing that the law threatens agricultural development.
Photos: researchers uncover top priority areas for Bolivian primates
(06/28/2010) Employing a predictive model, researchers have located two areas in need of protection to ensure the survival of Bolivia's primate species. The study, published in Tropical Conservation Science, identified the potential distribution of Bolivia's 22 primates and discovered two priority regions, one in the Pando Department with a number of rare primates, and the other in Western Beni, home to two primate species that live no-where else.
Invertebrates in Brazilian traditional medicines
(06/28/2010) According to a new study in Tropical Conservation Science a surprising number of invertebrates are used in Brazilian traditional medicines, which are popular both in rural and urban areas. Researcher discovered that at least 81 species from five taxonomic groups are being used to treat a variety of illnesses in Brazil.
Ending deforestation could boost Brazilian agriculture
(06/26/2010) Ending Amazon deforestation could boost the fortunes of the Brazilian agricultural sector by $145-306 billion, estimates a new analysis issued by Avoided Deforestation Partners, a group pushing for U.S. climate legislation that includes a strong role for forest conservation. The analysis, which follows on the heels of a report that forecast large gains for U.S. farmers from progress in gradually stopping overseas deforestation by 2030, estimates that existing Brazilian farmers could see around $100 billion from higher commodity prices and improved access to markets. Meanwhile landholders in the Brazilian Amazon—including ranchers and farmers—could see $50-202 billion from carbon payments for forest protection.
Environmentalists and indigenous groups condemn plan for six dams in Peruvian Amazon
(06/21/2010) Environmentalists and indigenous groups have come together to condemn a 15 million US dollar plan for six hydroelectric dams in the Peruvian Amazon, signed last week by Brazilian President Luiz Inácio Lula da Silva and Peruvian President, Alan Garcia. While the six dams would produce over 6,000 megawatts, mostly for Brazil, critics say the dams will flood tens of thousands of hectares of rainforest, devastate the lifestyles of a number of indigenous groups, and only serve big Brazilian corporations.
Amazon logging industry declines
(06/17/2010) The global economic crisis and increased environmental law enforcement have taken a toll on the Amazon logging industry in Brazil, reports a major new assessment conducted by Imazon and the Brazilian Forest Service.
Deforestation on the rise again in Brazil
(06/14/2010) Deforestation in the Brazilian Amazon may be on the rise again after reaching record-low levels last year, reports Brazil's National Space Research Institute, INPE.
Inga alley cropping: a sustainable alternative to slash and burn agriculture
(06/14/2010) It has been estimated that as many as 300 million farmers in tropical countries may take part in slash and burn agriculture. A practice that is environmentally destructive and ultimately unstable. However, research funded by the EEC and carried out in Costa Rica in the late 1980s and early 1990s by Mike Hands offers hope that it is possible to farm more successfully and sustainably in these tropical regions.
Second Act for South America: Are Greens the Answer?
(06/07/2010) Having overstated the political potency of Colombia’s Green Party, I've felt a bit shame faced in recent days. In the Andean nation's first presidential runoff election, Green Party candidate Antanas Mockus garnered more than 20% of the vote, which allowed him to proceed to the second round on June 20th. But while the news was certainly encouraging for environmentalists across South America, Mockus' electoral performance failed to live up to expectations.
As Amazon deforestation rates fall, fires increase
(06/03/2010) While rates of forest loss in the Brazilian Amazon have been on the decline since 2004, the incidence of fire is increasing in the region, undermining some of the carbon emissions savings of reduced deforestation rates, report researchers writing in the journal Science. The paper argues that REDD, a global plan to reduce deforestation and forest degradation, must include measures to eliminate the use of fire from land management in the Amazon.
Mexico has big role in the illegal parrot trade
(05/30/2010) Juan Carlos Cantu, Director of Defenders of Wildlife’s Mexico office, spoke with Laurel Neme on her The WildLife radio show and podcast about the illegal parrot trade in Mexico and how his innovative research into the trade was used by the Mexican Congress to reform that country’s Wildlife Law to ban all trade in parrots. The illegal pet trade is probably the second-biggest threat facing parrots in the wild, with only habitat loss rating higher, and the impact is disturbing. Defenders of Wildlife documented this threat in a 2007 landmark study which found between 65,000 and 78,500 parrots are illegally trapped in the wild in Mexico every year.
New bird discovered in Colombia—and released alive
(05/26/2010) Researchers have discovered a new species of antpitta in the montane cloud forests of the Colibri del Sol Bird Reserve in western Colombia. A thrush-like bird, the new cinnamon and gray species was, according to a press release by the American Bird Conservancy (ABC), "captured, banded, measured, photographed, sampled for DNA, and then released alive back into the wild". This is one of only a few incidences in which a new species has been described without 'collecting' an individual (i.e. killing) to provide a model of the species in a museum. The new bird has been named Fenwick's antpitta (Grallaria fenwickorum) after the President of ABC, George Fenwick, and his family.
'Prepare for war': tensions rising over Brazil's controversial Belo Monte dam
(05/25/2010) Tensions are flaring after Brazil's approval of the Belo Monte dam project last month to divert the flow of the Xingu River. The dam, which will be the world's third larges, will flood 500 square miles of rainforest, lead to the removal of at least 12,000 people in the region, and upturn the lives of 45,000 indigenous people who depend on the Xingu. After fighting the construction of the dam for nearly thirty years, indigenous groups are beginning to talk of a last stand.
More of the Amazon opened to oil development
(05/24/2010) Perupetro, the Peruvian government's oil and gas corporate leasing body, announced last week that it will open an additional 25 lots for oil and gas exploration in the Amazon covering an area of 10 million hectares (nearly 25 million acres). Peru's national Amazon indigenous group, AIDESEP, criticized the move calling it a 'new threat' to Peru's indigenous group. According to Amazon Watch these new lots mean that 75 percent of the Peruvian Amazon is now open to oil and gas exploration and drilling.
Long-distance seed dispersal and hunting, an interview with Kimberly Holbrook
(05/24/2010) Scientists are just beginning to uncover the complex relationship between healthy biodiverse tropical forests and seed dispersers—species that spread seeds from a parent tree to other parts of the forest including birds, rodents, primates, and even elephants. By its very nature this relationship consists of an incredibly high number of variables: how abundant are seed dispersers, which animals spread seeds the furthest, what species spread which seeds, how are human impacts like hunting and deforestation impacting successful dispersal, as well as many others. Dr. Kimberly Holbrook has begun to answer some of these questions.
Colombia’s Next President: A Renovation for the South American Left?
(05/17/2010) Mired in populist demagoguery and environmentally-unfriendly resource extraction, the South American left is in dire need of ideological renovation. But, where is the likely inspiration to come from? You could not pick a more unlikely candidate than Colombia, a key U.S. ally in the region. And yet, if recent polls are correct, the Green Party could be cruising toward electoral victory in the troubled Andean nation and is currently poised to capture the presidency.
Taking back the rainforest: Indians in Colombia govern 100,000 square miles of territory
(05/10/2010) Indigenous groups in the Colombian Amazon have long suffered deprivations at the hands of outsiders. First came the diseases brought by the European Conquest, then came abuses under colonial rule. In modern times, some Amazonian communities were virtually enslaved by the debt-bondage system run by rubber traders: Indians could work their entire lives without ever escaping the cycle of debt. Later, periodic invasions by gold miners, oil companies, colonists, and illegal coca-growers took a heavy toll on remaining indigenous populations. Without title to their land, organization, or representation, indigenous Colombians in the Amazon seemed destined to be exploited and abused. But new hope would emerge in the 1980s, thanks partly to the efforts of Martin von Hildebrand, an ethnologist who would help indigenous Colombians eventually win control over 260,000 square kilometers (100,000 square miles) of Amazon rainforest—an area larger than the United Kingdom.
Brazil launches major push for sustainable palm oil in the Amazon
(05/07/2010) Brazilian President Lula da Silva on Thursday laid out plans to expand palm oil production in the Amazon while minimizing risk to Earth's largest rainforest. The plan, called the Program for Sustainable Production of Palm Oil (O Programa de Produção Sustentável de Óleo de Palma), will provide $60 million to promote cultivation of oil palm in abandoned and degraded agricultural areas, including long-ago deforested lands used for sugar cane and pasture. Brazilian officials claim up to 50 million hectares of such land exist in the country.
Can markets protect nature?
(05/03/2010) Over the past 30 years billions of dollars has been committed to global conservation efforts, yet forests continue to fall, largely a consequence of economic drivers, including surging global demand for food and fuel. With consumption expected to far outstrip population growth due to rising affluence in developing countries, there would seem to be little hope of slowing tropical forest loss. But some observers see new reason for optimism—chiefly a new push to make forests more valuable as living entities than chopped down for the production of timber, animal feed, biofuels, and meat. While are innumerable reasons for protecting forests—including aesthetic, cultural, spiritual, and moral—most land use decisions boil down to economics. Therefore creating economic incentives to maintaining forests is key to saving them. Leading the effort to develop markets ecosystem services is Forest Trends, a Washington D.C.-based NGO that also organizes the Katoomba group, a forum that brings together a wide variety of forest stakeholders, including the private sector, local communities, indigenous people, policymakers, international development institutions, funders, conservationists, and activists.
Deforestation-free leather comes closer to reality in the Brazilian Amazon
(05/02/2010) Prominent leather buyers have developed a new traceability system to ensure that leather products from Brazil don't result in deforestation, reports the National Wildlife Federation, an NGO working to improve the environmental performance of the cattle industry in the Amazon.
Second rancher sentenced for contract killing of American nun in the Brazilian Amazon
(05/02/2010) A second rancher has been sentenced for his role in the murder of Dorothy Stang, an American nun who was gunned down in 2005 for her efforts on behalf of poor farmers in the Amazon rainforest, reports Reuters.
Large-scale soy farming in Brazil pushes ranchers into the Amazon rainforest
(04/28/2010) Industrial soy expansion in the Brazilian Amazon has contributed to deforestation by pushing cattle ranchers further north into rainforest zones, reports a new study published the journal Environmental Research Letters.
Alternative Climate Summit, Machu Picchu, and El Niño: Destroyer of Civilizations
(04/23/2010) As an alternative climate summit gets underway in the Bolivian city of Cochabamba, many in the Andean region are wondering how they will cope with El Niño, a cyclical meteorological phenomenon in which Pacific surface temperatures rise and have repercussions on weather around the world. El Niño takes place irregularly about every two to seven years and lasts from twelve to eighteen months.
