More big companies disclosing impacts on forests

2012-02-07T23:30:00Z

More companies are reporting on the impact of their operations on global forests, finds a new report. Eighty-seven global corporations disclosed their "forest footprint" in 2011, according to the third Forest Footprint Disclosure (FFD), which asks companies to report on their impact on forests based on their use of five commodities: soy, palm oil, timber and pulp, cattle, and biofuels. This is a 11 percent rise from the companies that reported in 2010, including the first reports by companies such as the Walt Disney Company, Tesco UK, and Johnson & Johnson. However a number of so-called "green" companies continue to refuse to disclose, including Patagonia, Stonyfield Farms, and Whole Foods Markets Inc.

Colonization program remains important driver of deforestation in Brazil

2012-01-10T13:58:00Z

Government-subsidized colonization of the Amazon rainforest remains an important driver of forest loss in Brazil, but has mixed economic value, argues a paper published in Biological Conservation.

Brazil passes controversial Forest Code reform environmentalists say will be 'a disaster' for the Amazon

2011-12-06T23:59:00Z

The Brazilian Senate tonight passed controversial legislation that will reform the country's 46-year-old Forest Code, which limits how much forest can be cleared on private lands. Environmentalists are calling the move "a disaster" that will reverse Brazil's recent progress in slowing deforestation in the world's largest rainforests.

Volcano and cloud forests conserved in Ecuador

2011-12-05T02:54:00Z

Conservation organizations and the Ecuadorian government have succeeded in securing over 250,000 acres (106,000 hectares) of cloud forest and grasslands surrounding the Antisana Volcano for protection. The area, long-used for cattle ranching, is home to Andean condors (Vultur gryphus), cougars (Puma concolor), Andean fox (Lycalopex culpaeus), silvery grebes (Podiceps occipitalis), black-faced ibis (Theristicus melanopis), spectacled bear (Tremarctos ornatus), and three species of endangered frogs. The protected area stretches from 3,900 feet (1,188 meters) to 18,700 feet (5,699 meters) above sea level.

African cattle benefit from socializing with wild grazers during the wet season

2011-11-08T05:21:00Z

Mingling with wild grazers, such as zebra, is better for cattle than dining alone—during the wet season, at least—according to researchers in Kenya. Their new study crumbles the longstanding assumption that social grazing always leads to food fights. Kenya’s wildlife population is in a critical decline, partly due to kill-offs by ranchers who see zebra, wildebeest, antelope and other grazers strictly as competition for their cattle. But scientists at the Mpala Research Center in central Kenya suspected there might be natural accords between grazers.

World's largest beef company breaks commitment on avoiding Amazon deforestation

2011-10-19T17:58:00Z

In a campaign launched in Italy on Wednesday, Greenpeace accused Brazilian beef giant JBS-Friboi of breaking its commitment to exclude cattle connected with illegal deforestation and slave labor from its supply chain.

Meat consumption jumps 20 percent in last decade with super-sized environmental impacts

2011-10-11T18:45:00Z

Meat consumption and production remains on the rise, according to a new report Worldwatch Institute, with large-scale environmental impacts especially linked to the spread of factory farming. According to the report, global meat production has tripled since 1970, and jumped by 20 percent since 2000 with consumption rising significantly faster than global population.

62% of deforested Amazon land ends up as cattle pasture

2011-09-04T19:19:00Z

62 percent of the area deforested in the Brazilian Amazon until 2008 is occupied by cattle pasture, reports a new satellite-based analysis by Brazil's National Institute for Space Research (INPE) and its Agricultural Research Corporation (Embrapa).

Saving (and studying) one of Nigeria's last montane forests

2011-07-26T15:33:00Z

Between 2000 and 2010, Nigeria lost nearly a third (31 percent) of its forest cover, while its primary forests suffered even worse: in just five years (2000 to 2005) over half of the nation's primary forests were destroyed, the highest rate in the world during that time. Yet, Nigeria's dwindling forests have never received the same attention as many other country's, such as Indonesia, Brazil, Malaysia, or Peru, even though in many ways Nigeria struggles with even deeper problems than other developing nations. Despite vast oil business, the nation is plagued by poverty and destitution, a prime example of what economists call the 'resource curse'. Environmentally, it has been named one of the worst in the world. Yet, not all forest news out of Nigeria is bleak: the success of the Nigerian Montane Forest Project in one of the country's remaining forests is one such beacon of hope, and one example of how the country could move forward.

Brazilian senator: Forest Code reform necessary to grow farm sector

2011-07-06T00:26:00Z

Over the past twenty years Brazil has emerged as an agricultural superpower: today it is the largest exporter beef, sugar, coffee, and orange juice, and the second largest producer of soybeans. While much of this growth has been fueled by a sharp increase in productivity resulting from improved breeding stock and technological innovation, Brazil has benefited from large expanses of available land in the Amazon and the cerrado, a grassland ecosystem. But agricultural growth in Brazil has always been limited — at least on paper — by its environmental laws. Under the country's Forest Code, landowners in the Amazon must keep 80 percent of their land forested.

Revised Forest Code may cost Brazil climate commitments

2011-06-14T22:32:00Z

The proposed revision of Brazil’s Forest Code could prevent the country from meeting its lower emissions target and is unlikely to ease rural poverty, concludes a new study by the Brazil-based Institute of Applied Economic Research (IPEA).

Could palm oil help save the Amazon?

2011-06-14T13:40:00Z

For years now, environmentalists have become accustomed to associating palm oil with large-scale destruction of rainforests across Malaysia and Indonesia. Campaigners have linked palm oil-containing products like Girl Scout cookies and soap products to smoldering peatlands and dead orangutans. Now with Brazil announcing plans to dramatically scale-up palm oil production in the Amazon, could the same fate befall Earth's largest rainforest? With this potential there is a frenzy of activity in the Brazilian palm oil sector. Yet there is a conspicuous lack of hand wringing by environmentalists in the Amazon. The reason: done right, oil palm could emerge as a key component in the effort to save the Amazon rainforest. Responsible production there could even force changes in other parts of the world.

Profit, not poverty, increasingly the cause of deforestation

2011-06-13T22:02:00Z

A new report highlights the increasing role commodity production and trade play in driving tropical deforestation.

Majority of Brazilians reject changes in Amazon Forest Code

2011-06-11T14:11:00Z

The vast majority of Brazilians reject a bill that would weaken Brazil's Forest Code, according to a new poll commissioned by green groups.

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.

Amnesty for illegal rainforest loggers moves forward in Brazil

2011-05-25T23:11:00Z

A controversial bill environmentalists say could increase deforestation in the Amazon rainforest moved a step forward to becoming law in Brazil after winning approval in Brazil's lower house of Congress. The measure, which has been hotly debated for months, next goes to the Senate where it is expected to pass, before heading to President Dilma Rousseff, who has vowed to veto any bill that grants amnesty for illegal deforestation. The bill includes such a measure, although it could be subject to change before a final decision by the president. The bill aims to reform Brazil's Forest Code, which requires landowners in the Amazon rainforest to maintain 80 percent of their holdings as forest.

Brazil’s new cabinet-level post in response to surge in deforestation

2011-05-21T05:00:00Z

Prompted by a near sixfold increase in Amazon rainforest clearing over the past year, the Brazilian government will form a cabinet post to monitor and respond to deforestation.

Brazil confirms big jump in Amazon deforestation

2011-05-18T17:49:00Z

New data from the Brazilian government seems to confirm environmentalists' fears that farmers and ranchers are clearing rainforest in anticipation of a weakening of the country's rules governing forest protection. Wednesday, Brazil's National Space Research Agency (INPE) announced a sharp rise in deforestation in March and April relative to the same period last year. INPE's rapid deforestation detection system (DETER) recorded 593 square kilometers of forest clearing during the past two months, a 473 percent increase over the 103.5 sq km chopped down from March-April 2010.

Brazil's forest code debate may determine fate of the Amazon rainforest

2011-05-05T17:08:00Z

Brazil's forest code may be about to get an overhaul. The federal code, which presently requires landowners in the Amazon to keep 80 percent of their land forest (20-35% in the cerrado), is widely flouted, but has been used in recent years as a lever by the government to go after deforesters. For example, the forest code served as the basis for the "blacklists" which restricted funds for municipalities where deforestation has been particularly high. To get off the blacklist, and thereby regain access to finance and markets, a municipality must demonstrate its landowners are in compliance with environmental laws.

NASA image reveals extent of deforestation in western Brazil

2011-05-04T16:06:00Z

The Brazilian state of Rondônia has undergone tremendous change over the past decade as revealed by the NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite. A hotspot for recent deforestation, Rondônia was once home to over 50 million acres (208,000 square kilometers of forest). By 2003 nearly a third of the rainforest in the state was gone and deforestation continues although at a slower pace. The state has the dubious honor of undergoing the highest percentage of forest loss in the Brazilian Amazon.

World's largest beef company signs Amazon rainforest pact

2011-04-29T15:37:00Z

The world's largest meat processor has agreed to stop buying beef from ranches associated with slave labor and illegal deforestation in the Brazilian Amazon, according to the public prosecutor's office in the state of Acre. The deal absolves JBS-Friboi from 2 billion reals ($1.3 billion) in potential fines and paves the way for the firm to continue selling meat to companies concerned about their environmental reputation.

Brazilian authorities levy $1.2B in fines against beef traders linked to deforestation, slave labor

2011-04-15T05:35:00Z

Brazilian authorities are seeking 2 billion reals ($1.2 billion) in fines against 14 companies accused of buying beef sourced from ranches that have illegally cleared Amazon rainforest or exploited workers in the state of Acre, reports AFP.

Satellite evidence of deforestation in uncontacted tribe's territory sparks legal action

2011-04-12T20:31:00Z

The destruction of 3,600 hectares (8,900 acres) of the Gran Chaco forest in Paraguay by large Brazilian cattle ranching companies has led to a legal complaint filed by a local indigenous-rights organization, since the land in question was one of the last refuges of a group of uncontacted indigenous people in the Ayoreo-Totobiegosode tribe. The loss of the forest was revealed in part by satellite images of the remote area.

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.

15 conservation issues to watch

2011-03-14T23:58:00Z

Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.

McDonald's launches new sourcing policy for palm oil, paper, beef to reduce global environmental impact

2011-03-11T00:07:00Z

McDonald's announced a far-reaching sourcing policy that could significantly reduce the fast-food giant's impact on the environment, including global forests. Yesterday McDonald's unveiled its Sustainable Land Management Commitment, a policy that requires its suppliers to use 'agricultural raw materials for the company's food and packaging that originate from sustainably-managed land'.

Deforestation gives some Brazil beef a big carbon footprint

2011-03-08T05:19:00Z

Extensive deforestation for low-yielding cattle production means some Brazilian beef carries a disproportionately high carbon footprint, reports a new study published in Environmental Science & Technology.

A lion's story, an interview with the filmmakers of The Last Lions

2011-02-14T03:18:00Z

The new theatrical film, The Last Lions does not open, as one would expect, with a shot of lions or even an African panorama. Instead the first shot is a view of our planet from space at night. Billions of artificial lights illuminate continent showing just how much humans over the past few thousand years have come to dominate our world. Then comes the lions, but not in person, just in this staggering, and little known, statistic: in the last 50 years we have gone from a population of 450,000 lions to 20,000 today, a 95% decline. While the dramatic story of the The Last Lions follows the perils and tragedies of lion motherhood in one of the world's last untouched places—the Okavango Delta—this statistic hangs over the film, reminding us that the story we are witnessing is on the verge of extinction.

From Cambodia to California: the world's top 10 most threatened forests

2011-02-02T19:44:00Z

Growing populations, expanding agriculture, commodities such as palm oil and paper, logging, urban sprawl, mining, and other human impacts have pushed many of the world's great forests to the brink. Yet scientists, environmentalists, and even some policymakers increasingly warn that forests are worth more standing than felled. They argue that by safeguarding vulnerable biodiversity, sequestering carbon, controlling erosion, and providing fresh water, forests provide services to humanity, not to mention the unquantifiable importance of having wild places in an increasingly human-modified world. Still, the decline of the world's forests continues: the FAO estimating that around 10 million hectares of tropical forest are lost every year. Of course, some of these forests are more imperiled than others, and a new analysis by Conservation International (CI) has catalogued the world's 10 most threatened forests.

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.

Consumer goods industry announces goal of zero deforestation in Cancun

2010-11-30T16:54:00Z

While governments continue to stall on action to cut greenhouse gas emissions worldwide, global corporations are promising big changes to tackle their responsibilities. The Board of Consumer Goods Forum (BCGF) has approved a resolution to achieve net zero deforestation by 2020 in products such as palm oil, soy, beef, and paper. Announced yesterday at the UN Climate Summit in Cancun, the BCGF has stated the goal will be met both by individual actions within companies and collective action, including partnerships with NGOs, development banks, and governments. With such giants as Walmart, Unilever, Carrefour, and General Mills, BCGF is made up of four hundred global consumer goods manufacturers and retailers totaling over $2.8 trillion in revenue.

Chaco expedition working to "minimize the risk" of running into uncontacted natives

Mato Grosso moves to strip protection of the Amazon rainforest

2010-11-07T17:17:00Z

The Mato Grosso state assembly passed a bill that would substantially reduce protections for the Amazon rainforest and the Pantanal, a biologically-rich wetland, according to a statement signed by 27 organizations. The bill, which was approved 19 votes to one, would replace the ecological zoning system proposed by the state's former governor, Blairo Maggi, after three years of consultations with a wide range of stakeholders. The bill reduces areas set aside for conservation by 73 percent and calls for a 67 percent increase in the area zoned for agriculture intensification.

Brazil's national development bank found guilty of driving Amazon deforestation

2010-10-25T18:06:00Z

BNDES, Brazil's national development bank, contributed to Amazon deforestation by lending billions of dollars to commercial meatpackers, driving expansion of cattle ranching across the world's largest rainforest, ruled an audit by the Federal Audit Court.

Corporations, conservation, and the green movement

2010-10-21T17:32:00Z

The image of rainforests being torn down by giant bulldozers, felled by chainsaw-wielding loggers, and torched by large-scale developers has never been more poignant. Corporations have today replaced small-scale farmers as the prime drivers of deforestation, a shift that has critical implications for conservation. Until recently deforestation has been driven mostly by poverty—poor people in developing countries clearing forests or depleting other natural resources as they struggle to feed their families. Government policies in the ’60s, ’70s, and ’80s had a multiplier effect, subsidizing agricultural expansion through low-interest loans, infrastructure projects, and ambitious colonization schemes, especially in the Amazon and Indonesia. But over the past two decades, this has changed in many countries due to rural depopulation, a decline in state-sponsored development projects, the rise of globalized financial markets, and a worldwide commodity boom. Deforestation, overfishing, and other forms of environmental degradation are now primarily the result of corporations feeding demand from international consumers. While industrial actors exploit resources more efficiently and cause widespread environmental damage, they also are more sensitive to pressure from consumers and environmental groups. Thus in recent years, it has become easier—and more ethical—for green groups to go after corporations than after poor farmers.

Walmart takes on Amazon deforestation

2010-10-18T19:52:00Z

The world's largest retailer last week announced new sourcing criteria for commodities closely associated with deforestation: palm oil and beef from the Amazon.

The ultimate bike trip: the Amazon rainforest

2010-10-17T16:46:00Z

Like all commercial roads through rainforests, the 5,300 kilometer long Rodovia Transamazonica (in English, the Trans-Amazonia), brought two things: people and environmental destruction. Opening once-remote areas of the Amazon to both legal and illegal development, farmers, loggers, and miners cut swathes into the forest now easily visible from satellite. But the road has also brought little prosperity: many who live there are far from infrastructure and eek out an impoverished existence in a harsh lonely wilderness. This is not a place even the most adventurous travelers go, yet Doug Gunzelmann not only traveled the entirety of the Transamazonica in 2009, he cycled it. A self-described adventurer, Gunzelmann chose to bike the Transamazonica as a way to test his endurance on a road which only a few before have completed. But Gunzelmann wasn't just out for adrenaline-rushes, he was also deeply interested in the environmental issues related to the Transamazonica. What he found was a story without villains, but only humans—and the Amazon itself—trying to survive in a complex, confusing world.

Can 'boutique capitalism' help protect the Amazon?

2010-10-11T18:37:00Z

Most companies talk green, but few—almost none in fact—actually walk the walk. Sustainable design company, Ecostasy, not only walks the walk, but actually seeks out among the most challenging places to work: the imperiled Brazilian Amazon. Specializing in hand-crafted products by indigenous groups—such as jewelry, pots, and furniture—Ecostasy seeks to balance smart economics, environmental protection, and community development. Make no mistake, however, Ecostasy is not a non-profit, but a rare and refreshing example of a company truly dedicated to changing the world for the better. "In my mind, a virtuous company does not compromise ethical principles for economic interests. For me, being ethical is comprised of conducting oneself with honesty and responsibility to one’s constituencies (customers, employees, suppliers), society and the environment," Katherine Ponte, founder of Ecostasy, told mongabay.com in an interview.

Logging generates more income than ranching in the Amazon

2010-10-04T05:37:00Z

New research conducted by Brazil's Federal Rural University of Amazonia (UFRA) found that logging generates more income from cattle grazing and agriculture in the Amazon provided landowners operate under existing social and environmental laws, reports the International Tropical Timber Organization in its bimonthly update.

80% of tropical agricultural expansion between 1980-2000 came at expense of forests

2010-09-02T20:47:00Z

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.

How Greenpeace changes big business

2010-07-22T15:01:00Z

Tropical deforestation claimed roughly 13 million hectares of forest per year during the first half of this decade, about the same rate of loss as the 1990s. But while the overall numbers have remained relatively constant, they mask a transition of great significance: a shift from poverty-driven to industry-driven deforestation and geographic consolidation of where deforestation occurs. These changes have important implications for efforts to protect the world's remaining tropical forests in that environmental groups now have identifiable targets that may be more responsive to pressure on environmental concerns than tens of millions of impoverished rural farmers. In other words, activists have more leverage than ever to impact corporate behavior as it relates to deforestation. A prime example of this power is evident in a string of successful Greenpeace campaigns, which have targeted some of the largest drivers of deforestation, including the palm oil industry in Indonesia and Malaysia and the soy and cattle industries in the Brazilian Amazon. The campaigns have shared a common approach: target large, conspicuous consumer-facing companies that sell in western markets.

Controversial changes to Brazilian forest law passes first barrier

Top officials busted in Amazon logging raids, but political patronage may set them free

2010-07-08T16:11:00Z

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

2010-07-08T16:10:00Z

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 and Atlantic Forest under threat: politicians press to dilute Brazil's forestry law

2010-07-01T16:55:00Z

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.
