Deforestation, climate change threaten the ecological resilience of the Amazon rainforest

2012-01-19T02:02:00Z

The combination of deforestation, forest degradation, and the effects of climate change are weakening the resilience of the Amazon rainforest ecosystem, potentially leading to loss of carbon storage and changes in rainfall patterns and river discharge, finds a comprehensive review published in the journal Nature.

Weird carnivorous flower devours worms underground

2012-01-09T20:10:00Z

A worm measuring only a millimeter in length scoots its way through relatively massive grains of white sand. The worm, known as a nematode or roundworm, is seeking lunch in the form of bacteria. Suddenly, however, its journey is interrupted: it is caught on a large green surface. Unable to wiggle free the worm is slowly digested, becoming lunch itself for an innocuous purple flower called Philcoxia minensis.

Estimating the rich diversity of galling insects

2011-12-12T18:45:00Z

How does one estimate the number of tiny, cryptic "galling" insects without finding and describing every one (a task that could take centuries of taxonomic work)? According to a new paper in mongabay.com's open access journal Tropical Conservation Science, you count the plants. Galling insects use plant tissue for development creating a "gall," or abnormal growth on the plant. Such little-known insects include gall wasps, gall midges, aphids, and jumping plant lice. The groups are known to be highly diverse, with over 2,000 species described from the US alone; scientists have previously estimated that there may be as many as 132,000 different species.

Loving the tapir: pioneering conservation for South America's biggest animal

2011-09-11T17:41:00Z

Compared to some of South America's megafauna stand-out species—the jaguar, the anaconda, and the harpy eagle come to mind—the tapir doesn't get a lot of love. This is a shame. For one thing, they're the largest terrestrial animal on the South American continent: pound-for-pound they beat both the jaguar and the llama. For another they play a very significant role in their ecosystem: they disperse seeds, modify habitats, and are periodic prey to big predators. For another, modern tapirs are some of the last survivors of a megafauna family that roamed much of the northern hemisphere, including North America, and only declined during the Pleistocene extinction. Finally, for anyone fortunate enough to have witnessed the often-shy tapir in the wild, one knows there is something mystical and ancient about these admittedly strange-looking beasts.

Taking corporate sustainability seriously means changing business culture

2011-08-11T07:10:00Z

As more and more people demand companies to become sustainable and environmentally conscious, many corporations are at a loss of how to begin making the changes necessary. If they attempt to make changes—but fall short or focus poorly—they risk their actions being labeled as 'greenwash'. In addition, if they implement smart changes and self-regulations, but their employees don't buy-in to the process, all their investments will be for nothing. This is where Accountability Now, a young, fresh social responsibility agency, comes in. Clare Raybould, director of Accountability Now, believes companies—large and small—have the potential to change the world for the better, but they simply need a guiding hand to change not just the way a company works, but its culture.

Despite moratorium, soy still contributes indirectly to Amazon deforestation

2011-07-15T17:20:00Z

Soy expansion in areas neighboring the Amazon rainforest is contributing to loss of rainforest itself, reports a new study published in Environmental Research Letters.

Can Brazil meet deforestation, climate goals and still grow its cattle industry?

2011-06-09T23:23:00Z

Despite environmentalists' efforts to combat "rainforest beef" in the 1980s, pasture expansion for cattle is still the primary cause of deforestation in the Brazilian Amazon, says a new report produced by Brighter Green. While Brazil's investments in agribusiness have made it an agricultural powerhouse—the country is now the world’s third-largest exporter of farm commodities after the US and the European Union—unfortunately, two of the Brazil’s key products, cattle and soy, are still driving deforestation as well as economic growth. According to Brighter Green’s report, researchers estimate that cattle ranching caused 65-70 percent of land clearing in the Amazon between 2000 and 2005.

Dutch buy first 'responsible' soy sourced from the Amazon

2011-06-08T19:46:00Z

The Dutch food and feed industry has bought the first soy produced under the principles of the Round Table on Responsible Soy (RTRS), a body that aims to bring more socially and environmentally sustainable soy to market.

Sugar cane cools climate when it replaces cattle pasture

2011-04-17T20:45:00Z

Converting cattle pasture and cropland in Brazil to sugar cane helps cool local climate reports research published in Nature Climate Change.

Conversion of Brazil's cerrado slows

2011-04-08T15:04:00Z

Destruction of Brazil's cerrado, a woody savanna that covers 20 percent of the country, slowed during the 2008-2009, reports Brazil's Ministry of Environment.

How to save the Pantanal and increase profits for the cattle industry

2011-03-28T17:25:00Z

The Pantanal spanning Brazil, Bolivia, and Paraguay is the world's largest wetland—the size of Florida—and home to a wide-variety of charismatic species, such as jaguars, capybaras, and giant anteaters. However, the great wetland is threatened by expansion in big agriculture and an increasingly intensive cattle industry. Yet there is hope: a new study by Wildlife Conservation Society of Brazil (WCS-Brazil) researchers has found that cattle and the ecosystem can exist harmoniously. By replacing current practices with rotational grazing, cattle ranchers gain a healthier herd and more profits while safeguarding the ecological integrity and wildlife of the world's largest wetland system. The study published in mongabay.com's open access journal Tropical Conservation Science is a rare instance of a win-win situation.

Agricultural lending jumps in Brazil, will Amazon deforestation follow?

2010-12-27T23:59:00Z

With commodity prices surging, lending to Brazilian farmers for tractors, harvesters and plows reached 8.2 billion reais ($4.8 billion) for the July through November 2010 period, a 64 percent increase since the same period last year and the fastest pace since 2004, reports Bloomberg.

Brazil's largest national bank signs zero deforestation pact for Amazon soy

2010-12-03T03:46:00Z

Banco do Brasil, Brazil's largest state-owned bank, announced it has joined a zero deforestation pact for soy grown in the Amazon. The bank will now require farmers applying for credit to certify the origin of their soybeans.

Brazil's cerrado wins protection, but will it be enough to save the wildlife-rich grassland?

2010-09-15T23:49:00Z

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.

U.S. signs debt-for-nature swap with Brazil to protect forests

2010-08-13T15:37:00Z

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.

Amazon rainforest will bear cost of biofuel policies in Brazil

2010-02-08T19:58:00Z

Business-as-usual agricultural expansion to meet biofuel production targets for 2020 will take a heavy toll on Brazil's Amazon rainforest in coming years, undermining the potential emissions savings of transitioning from fossil fuels to biofuels, warns a new paper published in the Proceedings of the National Academy of Sciences (PNAS). The research suggests that intensification of cattle ranching, combined with efforts to promote high-yielding oil crops like oil palm could lessen forecast greenhouse gas emissions from indirect land use in the region.

Ecological benefits of REDD boosted by inclusion of private landowners, potentially harmed by plantations

2009-11-17T05:06:00Z

Reducing Emissions from Deforestation and Degradation [REDD] programs that include landowners will conserve more habitat and ensure greater ecosystem services function than programs that focus solely on protected areas, report researchers from the Woods Hole Research Center (WHRC), the Instituto de Pesquisa Ambiental da Amazônia (IPAM), and the Universidade Federal de Minas Gerais (UFMG).

Emissions from cerrado destruction in Brazil equal to emissions from Amazon deforestation

2009-09-15T16:12:00Z

Damage to Brazil's vast cerrado grassland results in greenhouse gas emissions equivalent to those produced by destruction of the Amazon rainforest, said Carlos Minc, the country's Environment Minister.

Brazil to step up efforts to save the cerrado grassland

2009-09-11T14:46:00Z

Brazil will try to reduce deforestation of the cerrado, a wooded grassland ecosystem in Brazil that is being destroyed twice as fast as the Amazon rainforest, according to the country's Environment Minister Carlos Minc.

Concerns over deforestation may drive new approach to cattle ranching in the Amazon

2009-09-08T20:50:00Z

While you're browsing the mall for running shoes, the Amazon rainforest is probably the farthest thing from your mind. Perhaps it shouldn't be. The globalization of commodity supply chains has created links between consumer products and distant ecosystems like the Amazon. Shoes sold in downtown Manhattan may have been assembled in Vietnam using leather supplied from a Brazilian processor that subcontracted to a rancher in the Amazon. But while demand for these products is currently driving environmental degradation, this connection may also hold the key to slowing the destruction of Earth's largest rainforest.

Extinction risk for Amazonian plants may be lower than previously estimated

2009-07-06T19:55:00Z

Five to nine percent of the Amazon's 40,000 known species of plants will be at risk of extinction by 2050 should current deforestation trends continue, report researchers writing in the Proceedings of the National Academy of Sciences. The estimates are sharply lower than the 20 to 33 percent predicted in other studies.

Mysterious decline of small mammals in Bolivia may be linked to burning Amazon

2009-04-19T19:21:00Z

During ten years surveying small mammal populations in Bolivia's cerrado, Dr. Louise Emmons with the Smithsonian Institute found that the mammals were suffering precipitous declines, even local extinctions. After ruling out the usual suspects—local fires, rainfall, and flooding—Emmons formed a novel hypothesis regarding the decline. Could a sudden lack of nighttime dew caused by the burning of the Amazon be the cause of the mammal decline?

Rainforest soy moratorium shows success in the Brazilian Amazon

2009-04-15T12:50:00Z

An industry-led moratorium on soy plantings on recently deforested rainforest land continues to show success in the Brazilian Amazon, reports a study released Tuesday by environmental groups and Abiove, the soy industry group that formed the initiative and represents about 90 percent of Brazil's soy crush. The satellite-based study showed that only 12 of 630 sample areas (1,389 of 157,896 hectares) deforested since July 2006 — the date the moratorium took effect — were planted with soy.

Beef drives 80% of Amazon deforestation

2009-01-29T20:12:00Z

Nearly 80 percent of land deforested in the Amazon from 1996-2006 is now used for cattle pasture, according to new maps released today in a report by Greenpeace at the World Social Forum in Belem, Brazil. The report, Amazon Cattle Footprint: Mato Grosso: State of Destruction, confirms that cattle ranching is the primary driver of deforestation in Earth's largest rainforest: the Brazilian Amazon.

Biofuels can reduce emissions, but not when grown in place of rainforests

2008-07-22T14:30:39Z

Biofuels meant to help alleviate greenhouse gas emissions may be in fact contributing to climate change when grown on converted tropical forest lands, warns a comprehensive study published earlier this month in the journal Environmental Research Letters. Analyzing the carbon debt for biofuel crops grown in ecosystems around the world, Holly Gibbs and colleagues report that "while expansion of biofuels into productive tropical ecosystems will always lead to net carbon emissions for decades to centuries... [expansion] into degraded or already cultivated land will provide almost immediate carbon savings." The results suggest that under the right conditions, biofuels could be part of the effort to reduce humanity's carbon footprint.

Photos of newly discovered species in Brazil's Cerrado

2008-04-29T14:30:39Z

An expedition to Brazil's Cerrado has turned up more than a dozen undiscovered species. conservationists say the discoveries add urgency to protecting the grassland habitat which is rapidly being converted for agriculture.

Amazon deforestation surging due to oil, soy prices

2008-01-17T14:30:39Z

A Brazilian scientist has confirmed that forest clearing in the Amazon rainforest has surged in recent months, according to Reuters.

Tree resprouting offers hope in former pastures of Brazil's cerrado

2007-09-06T14:30:39Z

Deforested landscapes in the Brazilian cerrado show hopeful signs of recovery even after long periods of intensive use, reports a study published in the journal Biotropica. Analyzing the natural reestablishment of native trees in former pastureland located in the dry woodlands of the Brazilian cerrado, a team of researchers found that while species richness was lower in older pasture, density and composition of regenerating trees did not change with pasture age.

Biofuels driving destruction of Brazilian cerrado

2007-08-21T14:30:39Z

The cerrado, wooded grassland in Brazil that once covered an area half the size of Europe, is fast being transformed into croplands to meet rising demand for soybeans, sugarcane, and cattle. The cerrado is now disappearing more than twice as the rate as the neighboring Amazon rainforest, according to a Brazilian expert on the savanna ecosystem.

Can cattle ranchers and soy farmers save the Amazon?

2007-06-06T14:30:00Z

John Cain Carter, a Texas rancher who moved to the heart of the Amazon 11 years ago and founded what is perhaps the most innovative organization working in the Amazon, Alianca da Terra, believes the only way to save the Amazon is through the market. Carter says that by giving producers incentives to reduce their impact on the forest, the market can succeed where conservation efforts have failed. What is most remarkable about Alianca's system is that it has the potential to be applied to any commodity anywhere in the world. That means palm oil in Borneo could be certified just as easily as sugar cane in Brazil or sheep in New Zealand. By addressing the supply chain, tracing agricultural products back to the specific fields where they were produced, the system offers perhaps the best market-based solution to combating deforestation. Combining these approaches with large-scale land conservation and scientific research offers what may be the best hope for saving the Amazon.

Globalization could save the Amazon rainforest

2007-06-03T14:30:00Z

The Amazon basin is home to the world's largest rainforest, an ecosystem that supports perhaps 30 percent of the world's terrestrial species, stores vast amounts of carbon, and exerts considerable influence on global weather patterns and climate. Few would dispute that it is one of the planet's most important landscapes. Despite its scale, the Amazon is also one of the fastest changing ecosystems, largely as a result of human activities, including deforestation, forest fires, and, increasingly, climate change. Few people understand these impacts better than Dr. Daniel Nepstad, one of the world's foremost experts on the Amazon rainforest. Now head of the Woods Hole Research Center's Amazon program in Belem, Brazil, Nepstad has spent more than 23 years in the Amazon, studying subjects ranging from forest fires and forest management policy to sustainable development. Nepstad says the Amazon is presently at a point unlike any he's ever seen, one where there are unparalleled risks and opportunities. While he's hopeful about some of the trends, he knows the Amazon faces difficult and immediate challenges.

Two 'dragon' species discovered in Brazil

2007-01-24T14:30:39Z

Two previously unknown species of lizard that are said to resemble miniature ground-dwelling dragons have been found in the threatened cerrado region of Brazil. The species, Stenocercus squarrosus and Stenocercus quinarius are described in the current issue of the South American Journal of Herpetology.

Hudson Institute calls Amazon savanna biome a wasteland

2006-04-23T15:19:39Z

In an April 21st, 2006 editorial published in the Canada Free Press Dennis T. Avery, senior fellow for Hudson Institute in Washington, DC and the Director for Global Food Issues, called Brazil's cerrado ecosystem a "wasteland" and criticized a recent report from the environmental activist group Greenpeace that linked Amazon deforestation to soy-based animal feed used by fast-food chains in Europe.

Greenpeace accuses McDonald's of destroying the Amazon rainforest

2006-04-07T15:19:39Z

After a year-long investigation, environmental group Greenpeace has accused McDonald's and other western firms of contributing to deforestation in the Amazon. Greenpeace's report, published today, alleges that much of the soy-based animal feed used by fast-food chains to fatten chickens is derived from soybeans grown in the Amazon Basin of Brazil. Thanks to a new variety of soybean developed by Brazilian scientists to flourish in rainforest climate, soybean production has boomed in the region in recent years as firms have converted extensive areas of rainforest and cerrado, a savanna-like ecosystem, into industrial soybean farms. High soybean prices have also served as an impetus to expanding soybean cultivation and Brazil is on the verge of supplanting the United States as the world's leading exporter of soybeans.

Brazil's grasslands could replace food production of American heartland

2005-08-01T15:19:39Z

Today when people mention Brazil and agriculture, people often first envision the Amazon rainforest giving way to soybean plantations and cattle farms. While the Amazon is being converted for such purposes, the cerrado, a vast area of savanna-like grasslands covering more than 20% of the country's surface area, is increasingly under threat as farmers from the United States and Europe are setting their sights on the country's sizeable agricultural potential.
