Amazon farming technique may fight global warming

(04/11/2008) Fifteen hundred years ago, tribes people from the central Amazon basin mixed their soil with charcoal derived from animal bone and tree bark. Today, at the site of this charcoal deposit, scientists have found some of the richest, most fertile soil in the world. Now this ancient, remarkably simple farming technique seems far ahead of the curve, holding promise as a carbon-negative strategy to rein in world hunger as well as greenhouse gases.


Land invasions undermine Amazon forest law

(04/03/2008) Land invasions are undermining a Brazilian law that requires ranchers to keep 80 percent of their land forested, according to reports from the Amazon state of Mato Grosso. A run up in land prices, driven by surging soy and cattle production in the region, combined with a lackadaisical response from law enforcement authorities are blamed for the incursions.


Amazon soy ban seems to be effective in reducing explicit deforestation

(04/03/2008) An industry-led ban on soy production in the Amazon appears to be proving effective at reducing new clearing for explicit soy production, according to a survey published Monday by Greenpeace and the Brazilian Vegetable Oils Industry Association. The moratorium, which was signed by some of the largest soy crushers in the Amazon in response to a campaign by environmental group Greenpeace, went into effect in October 2006. While soy is believed to be having an indirect impact on deforestation by driving up land prices and competing with the dominant form of land use in the Amazon — cattle ranching — the news is a hopeful sign for conservationists.


Investing to save rainforests

(04/02/2008) Last week London-based Canopy Capital, a private equity firm, announced a historic deal to preserve the rainforest of Iwokrama, a 371,000-hectare reserve in the South American country of Guyana. In exchange for funding a "significant" part of Iwokrama's $1.2 million research and conservation program on an ongoing basis, Canopy Capital secured the right to develop value for environmental services provided by the reserve. Essentially the financial firm has bet that the services generated by a living rainforest — including rainfall generation, climate regulation, biodiversity maintenance and carbon storage — will eventually be valuable in international markets. Hylton Murray-Philipson, director of Canopy Capital, says the agreement — which returns 80 percent of the proceeds to the people of Guyana — could set the stage for an era where forest conservation is driven by the pursuit of profit rather than overt altruistic concerns.


Private equity firm buys rights to ecosystem services of Guyana rainforest

(03/27/2008) A private equity firm has purchased the rights to environmental services generated by 371,000 hectare rainforest reserve in Guyana. Terms of the deal were not disclosed, but the agreement is precedent-setting in that a financial firm is betting that the services generated by a living rainforest — including rainfall generation, climate regulation, biodiversity maintenance and water storage — will eventually see compensation in international markets.


No global warming link to dying frogs?

(03/25/2008) Scientists have fired another salvo in the heated debate over the role of climate change in the global decline of amphibians. Writing in the March 25 issue of PLoS Biology, a team of researchers led by Karen Lips of Southern Illinois University-Carbondale report finding "no evidence to support the hypothesis that climate change has been driving outbreaks of amphibian chytridiomycosis" -- a disease blamed for large-scale die-offs of amphibians. Other researchers have argued that climate shifts are worsening the outbreak of the fungal disease.


Railroad could reduce Amazon deforestation relative to proposed highway

(03/24/2008) Building a railroad instead of improving a major highway could reduce deforestation and biodiversity loss in the heart of the Amazon rainforest says an Brazilian environmental group.


Do parks worsen deforestation through 'leakage'?

(03/17/2008) The creation of protected reserves may be pushing development to neighboring areas, confounding overall conservation efforts in regions where development pressures are high. Such "leakage" -- as the displacement is called -- makes it difficult to assess the effectiveness of protected areas strategies.


Amazon environmentalist gunned down in Peru

(03/14/2008) After reporting a truck loaded with mahogany illegally logged from the Amazon rainforest, Don Julio Garcia Agapito, a Peruvian environmentalist was gunned down by unknown assailants on February 26th, 2008. He is survived by his family.


Rare jewel-colored frog rediscovered in Colombia

(03/13/2008) A brilliantly-colored frog has been rediscovered 14 years after its last sighting in a remote mountainous region in Colombia.


Predator of the world's largest macaw key to its survival

(03/13/2008) In a bizarre biological twist, a new study shows that the Hyacinth Macaw depends on its greatest predator, the Toco Toucan, for continued survival.


Industry-driven road-building to fuel Amazon deforestation

(03/12/2008) Unofficial road-building will be a major driver of deforestation and land-use change in the Amazon rainforest, according to an analysis published in Philosophical Transactions of the Royal Society B. Improved governance, as exemplified by the innovative MAP Initiative in the southwestern Amazon, could help reduce the future impact of roads, without diminishing economic prospects in the region.


Cellulosic energy may trigger dramatic collapse in the Amazon

(03/11/2008) Next generation biofuels may trigger the ecological collapse of the Amazon frontier and could have profoundly unexpected economic consequences for the region, warns a paper published in Philosophical Transactions of the Royal Society B. Dr. Donald Sawyer writes that "interacting with climate change and land use, the upcoming stage of cellulosic energy could result in a collapse of the new frontier into vast degraded pasture." The shift could increase the incidence and severity of fires, reduce rainfall in key agricultural zones, exacerbate forest die-back and climate change, and worsen social instability. Sawyer says that while difficult to anticipate, the worst outcomes could likely be avoided be promoting "intensified and more sustainable use" of already cleared areas, minimizing new deforestation, and encouraging "sustainable use of natural resources by local communities."


Emissions from deforestation offset by increased tree growth in the Amazon

(03/10/2008) An increase in carbon sequestration by trees in the Amazon has roughly offset total emissions from deforestation in the region since the 1980s. A new study, published in Philosophical Transactions of the Royal Society B, this trend may slow in the future, causing the world's largest rainforest to become a net source of carbon emissions and therefore contributing to climate change.


Small fires a big threat to Amazon rainforest biodiversity

(02/27/2008) Small fires have a big impact in the Amazon rainforest, report researchers writing in Philosophical Transactions of the Royal Society B. The findings suggest a dire future for Earth's largest rainforest.


Greenhouse gas emissions have already caused the Amazon to dry

(02/27/2008) Anthropogenic emissions of greenhouse gases have already caused the Amazon to dry, finds a new study published in Philosophical Transactions of the Royal Society B.


Deforestation a greater threat to the Amazon than global warming

(02/25/2008) If past conditions are any indication of future conditions, the Amazon rainforest may survive considerable drying and warming caused by global warming, argue researchers in a paper published in Philosophical Transactions of the Royal Society B.


Brazil seeks $1B/yr in donations to save the Amazon

(02/23/2008) Brazil will establish a donation-based fund to help finance conservation in the Amazon, according to Bloomberg. The announcement comes after deforestation rates spiked during the last five months of 2007.


Large-scale Amazon deforestation or drying would have dire global consequences

(02/21/2008) A new study shows that large-scale degradation of the Amazon, either through drying or continued deforestation, would have global consequence, including worsening climate change, causing regional vegetation shifts, and increasing dust in the atmosphere.


Is Guyana's logging deal in its best interests?

(02/21/2008) In January Guyana awarded U.S. timber firm Simon & Shock International a 400,000-hectare (988,400-acre) logging concession near the Brazilian border. Final approval hinges on the completion of an environmental impact survey and a tree inventory. While Simon & Shock International says it plans to conduct selective logging, the firm has not announced whether it will seek Forest Stewardship Council certification, a mark for responsibly-harvested timber. Is there an alternative that can improve the lot for the average Guyanese? There may be. Last fall Guyana's President, Bharrat Jagdeo, hinted at the potential of using the country's forests as a giant carbon offset to counter climate change.


Amazon state launches Zero Extinction Program for endangered species

(02/21/2008) The Brazilian state of Para has launched the Zero Extinction Program, an initiative to prevent threatened species from going extinct by protecting their habitats.


Ancient Amazon fires linked to human populations

(02/20/2008) Analysis of soil charcoal in South America confirms that from a historical perspective, fire is rare in the Amazon rainforest, but when it does occur, it appears linked to human activities. The research, published in Philosophical Transactions of the Royal Society B, is based on dating of soil carbon, which provides a good indication of when fires occurred in Amazonia, according to lead author Mark Bush, head of the Department of Biology at Florida Institute of Technology.


Global warming - not el Nino - drove severe Amazon drought in 2005

(02/20/2008) One of the worst droughts on record in the Amazon was caused by high temperatures in the Atlantic rather than el Nino. The research, published in Philosophical Transactions of the Royal Society B, suggests that human-driven warming is already affecting the climate of Earth's largest rainforest.


Fire policy is key to reducing the impact of drought on the Amazon

(02/19/2008) Gaining control over the setting of fires for land-clearing in the Amazon is key to reducing deforestation and the impact of severe drought on the region's forests, write researchers in a paper published in Philosophical Transactions of the Royal Society B.


Small Amazon farmers especially vulnerable to climate change

(02/19/2008) Communicating the impact of climate change to small farmers in the Amazon will be key in helping them adapt to higher temperatures, more frequent and intense drought, and greater incidence of forest fires forecast for the region, according to a paper published in Philosophical Transactions of the Royal Society B.


Amazon riparian zones need to be expanded to protect wildlife finds study

(02/19/2008) Strips of forest mandated by Brazilian law along rivers and streams in the Amazon rainforest are too narrow to effectively safeguard biodiversity, reports new research published in the journal conservation Biology.


conservation strategies can mitigate the impact of global warming in the Amazon

(02/19/2008) Careful design of protected areas to safeguard key "refugia" and allow for migration can increase the resilience of Amazon biodiversity to climate change, report researchers writing in Philosophical Transactions of the Royal Society B.


Cheap ranch loans may be driving jump in Amazon deforestation

(02/12/2008) Surging deforestation in the Brazilian Amazon may be partly the result of new financial incentives given by state banks such as the Bank of Amazon (BASA), reports Agencia de Noticias da Amazonia, a Brazilian newspaper, and the International Tropical Timber Organization (ITTO).


Steel production drives deforestation in Brazil's Pantanal

(02/11/2008) A steel mill in Corumbá, in the heart of Brazil's Pantanal wetland, is fueling destruction of forests for charcoal and undermining the rights of Amazonian forest dwellers, reports the Inter Press Service.


France blocks controversial rainforest gold mine in French Guiana

(02/06/2008) Environmentalists declared victory after the French government blocked approval of a controversial gold mine bordering the Kaw wetland, an ecologically rich site in French Guiana. The decision was handed down last week following an environmental assessment by the Ministry of Ecology and Sustainable Development based on work by local scientists.


New uakari monkey discovered in the Amazon rainforest

(02/05/2008) A previously unknown species of uakari monkey was discovered in the Brazilian Amazon, reports National Geographic News. The primate was identified after it was killed by Yanomamo Indians near the Brazil-Venezuela border.


How much would it cost to end Amazon deforestation?

(01/27/2008) With Brazil last week announcing a significant jump in Amazon deforestation during the second half of 2007, the question emerges, how much would it cost to end the destruction of Earth's largest rainforest?


7000 sq km of Amazon rainforest destroyed in late 2007 says Greenpeace

Amazon deforestation jumps in the second half of 2007

(01/24/2008) Deforestation in the Brazilian Amazon rose sharply in the second half of 2007 as a result of surging prices for beef and grain, said a top Brazilian environmental official.


55% of the Amazon may be lost by 2030

(01/23/2008) Cattle ranching, industrial soy farming, and logging are three of the leading drivers of deforestation in the Brazilian Amazon. As commodity prices continue to rise, driven by surging demand for biofuels and grain for meat production, the economic incentives for developing the Amazon increase. Already the largest exporter of beef and the second largest producer of soy - with the largest expanse of "undeveloped" but arable land of any country - Brazil is well on its way to rivaling the U.S. as the world's agricultural superpower. The trend towards turning the Amazon into a giant breadbasket seems unstoppable. Nevertheless the decision at the U.N. climate talks in Bali to include "Reducing Emissions From Deforestation and Degradation" (REDD) in future climate treaty negotiations may preempt this fate, says Dr. Daniel Nepstad, a scientist at the Woods Hole Research Institute.


Malaysian timber firm fined for illegal rainforest logging in Guyana

(01/21/2008) Barama Company Limited, a subsidiary of the Samling Group, a Malaysian logging firm, has been fined for violating Guyana's forest laws, reports Staebroek News. Barama operates the largest timber concession in Guyana.


U.S. biofuels policy drives deforestation in Indonesia, the Amazon

(01/17/2008) U.S. incentives for biofuel production are promoting deforestation in southeast Asia and the Amazon by driving up crop prices and displacing energy feedstock production, say researchers.


Amazon deforestation surging due to oil, soy prices

(01/17/2008) A Brazilian scientist has confirmed that forest clearing in the Amazon rainforest has surged in recent months, according to Reuters.


Politics and the Amazon

(01/14/2008) In terms of environmental conservation, the Amazon is a logistics nightmare. How does Brazil protect 4.2 million square kilometers of forest with a border of 10.938 km?


An interview with primate researcher Dr. Karen Strier: America's largest monkey recovering after brush with extinction

(01/10/2008) The Atlantic forest of Brazil boasts South America's largest primates, the Southern and Northern Muriqui. The muriqui are unique among all primates, because they are not territorial and do not display aggressive behvaior. The IUCN has classified the Southern Muriqui as endangered, while the Nothern Muriqui is critically endangered. Dr. Karen Strier has studied the Northern Muriqui in the field for twenty-five years. A professor of zoology and anthropology at the University of Madison Wisconsin, she is the author of Faces in the Forest: the Endangered Muriqui Monkeys of Brazil and a new textbook entitled Primate behvaioral Ecology.


Nature tourism taking a toll in the Galapagos

(01/05/2008) A booming "ecotourism" industry is bringing new threats to the Galapagos, reports a feature in the Wall Street Journal.


Brazil bans illegal soy and cattle production in the Amazon rainforest

(12/24/2007) The Brazilian government launched a new initiative to slow deforestation in the Amazon, setting the stage for the country to potentially earn billions from carbon trading schemes set in motion two weeks ago at the U.N. climate meeting in Bali.


Migrating frogs fare poorly when habitat altered

(12/19/2007) Habitat loss and fragmentation are putting amphibians already threatened by climate change, pesticides, alien invasive species, and the outbreak of a deadly fungal infection at greater risk of extinction, reported a study published in Science last week.


U.S. corn subsidies drive Amazon destruction

(12/13/2007) U.S. corn subsidies for ethanol production are contributing to deforestation of the Amazon rainforest, reports a tropical forest scientist writing in this week's issue of the journal Science.


Amazon conservation Team wins "Innovation in conservation Award" for path-breaking work with Amazon tribes

(12/11/2007) The Amazon conservation Team (ACT) was today awarded mongabay.com's inaugural "Innovation in conservation Award" for its path-breaking efforts to enable indigenous Amazonians to maintain ties to their history and cultural traditions while protecting their rainforest home from illegal loggers and miners.


Controversial dam in the Amazon gets Brazilian go-ahead

(12/11/2007) The Brazilian government has awarded rights to build and operate a controversial R$10bn hydroelectric power plant on the Madeira river in the Amazon rainforest near the border with Bolivia, according to FT.com.


A comprehensive look at the use of animals in Brazilian medicine

(12/10/2007) For millennia animals have been used in medicine as remedies. While this practice has all but disappeared in western countries, many cultures still employ traditional medicine that includes animal-derived remedies. Probably the most famous of these are the Chinese, who for example use seahorses for a variety of ailments and rhinoceros horn as an aphrodisiac. Lesser known and studied, though just as varied and rich is Brazil's long tradition of animal-remedies for all kinds of ailments. A recent study set out to document the wide-range of animals used in Brazilian traditional medicine and its possible consequences on animal populations, the environment, and Brazilian society.


Amazon deforestation rates drop 20% in 2007

(12/08/2007) Deforestation rates in Brazil's Amazon rainforest dropped 20 percent since last year, reported the Brazilian National Institute of Space Research (INPE).


Global warming accelerates destruction of the Amazon

(12/06/2007) Deforestation and climate change could damage or destroy as much as 60 percent of the Amazon rainforest by 2030, according to a new report from environmental group WWF. The report, The Amazon's Vicious Cycles: Drought and Fire in the Greenhouse, shows that degradation in the Amazon could release 55-97 million tons of carbon dioxide by 2030. Forest loss could also dramatically impact water cycles in the region, affecting rainfall that is critical for river flows and agriculture.


Tropical forests face huge threat from industrial agriculture

(12/05/2007) With forest conversion for large-scale agriculture rapidly emerging as a leading driver of tropical deforestation, a new report from the Woods Hole Research Center (WHRC) suggests the trend is likely to continue with Brazil, the Democratic Republic of the Congo, Indonesia, Peru, and Colombia containing 75 percent of the world's forested land that is highly suitable for industrial agriculture expansion. Nevertheless the study identifies forests that may be best suited (low population density, unsuitable climate and soils) for "Reduced Emissions from Deforestation and Degradation" (REDD) initiatives which compensate countries for preserving forest lands in exchange for carbon credits.
