Soybeans may worsen drought in the Amazon rainforest

(04/18/2007) The rapid expansion of soybean cultivation in the Amazon may be having a larger impact on climate than previously believed, according to research published last week in Geophysical Research Letters. Using experimental plots in the Amazon, a team of scientists led by Marcos Costa from the Federal University of Vicosa in Brazil found that clearing for soybeans increases the reflectivity or albedo of land, reducing rainfall by as much as four times relative to clearing for pasture land.


Cargill busted in the Amazon rainforest

(03/26/2007) Brazilian authorities have shut down Cargill Incorporated's deepwater soy export terminal on the Amazon River reports the Associated Press. The action comes after a local judge ruled that the firm failed to prepare a proper environmental impact statement for the project.


Amazon rainforest fires date back thousands of years

(03/14/2007) Fires are nothing new to the Amazon reports a study published in the journalBiotropica. Analyzing soils in the eastern Amazon, a team of scientists led by David S. Hammond of NWFS Consulting, has found evidence of forest fires dating back thousands of years. While the origin of these fires is unclear, the authors propose intriguing scenarios involving pre-Colombian human populations and ancient el Nino events which could have so dried rainforest areas that they became more prone to forest fires.


Indigenous populations deforested New World rainforests before European contact

(02/28/2007) Indigenous populations used fire to clear large areas of tropical forest well before the arrival of Europeans reports a new study published in Annals of the Missouri Botanical Garden. The research has important implications for understanding the impact of present forest development on biodiversity and forest regeneration in the tropics.


Biofuels, logging may spur deforestation in Guyana

(02/15/2007) Growing timber exports and rising interest in biofuels are raising concerns that deforestation could accelerate in the South American country of Guyana. Guyana is a small, lightly populated country on the north coast of South America. About three-quarters of Guyana is forested, roughly 60 percent of which is classified as primary forest. Guyana's forests are highly diverse: the country has some 1,263 known species of amphibians, birds, mammals, and reptiles, and 6,409 species of plants.


New maps reveal causes of Amazon deforestation

(01/26/2007) Brazil's National Statistics Office (IBGE) released a set of maps showing how farmers are converting the Amazon rainforest into cattle pasture and soybean farms. The maps show for the first time the impact of deforestation and agricultural expansion on the Amazon rainforest, according to the agency.


Brazil claims soy and beef not responsible for Amazon deforestation

(10/26/2006) Brazil rejected claims that soybean farms and cattle pasture were destroying the Amazon rainforest, according to a report from Reuters. At the opening of an organic food products fair in Sao Paulo, Agriculture Minister Luis Carlos Guedes Pinto said that only 0.27 percent of Brazil's soybean crop is grown in the Amazon region, while less than 1.5 percent of Brazil's beef for export comes from the rainforest.


Expansion of agriculture in the Amazon may impact climate

(09/19/2006) A new study from NASA scientists shows that forest clearing for large-scale agriculture has recently become a significant cause of deforestation in the Brazilian Amazon. The researchers warn that this change in land use may affect the region' climate and the Amazon's ability to absorb carbon dioxide, a potent greenhouse gas.


Amazon soy becomes greener

(07/25/2006) Brazilian soy crushers and exporters will implement a two-year moratorium on trading soybeans grown on newly deforested lands in the Amazon basin. The governance program takes effect in October 2006 and applies only to forest cleared after that date.


Amazon Port Pits Farmers Vs. Rainforest

(07/18/2006) When U.S. grain giant Cargill opened a $20 million port in this sleepy Amazon River city three years ago, it expected to cash in on the rising global demand for soybeans that had become Brazil's richest agricultural export.


Hudson Institute calls Amazon savanna biome a wasteland

(04/23/2006) 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

(04/07/2006) 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.


Pre-Columbian Amazon supported millions of people

(10/18/2005) Controversial evidence uncovered over the past decade suggests that the Amazon rainforest was once home to large sedentary populations of people. Besides the well-known empires of the Inca and their predecessors, the Huari, millions of people once lived in the forests and shaped the environment to suit their own needs.


Amazon deforestation lower than last year says Brazil

(08/27/2005) Yesterday Brazil announced that 3,515 square miles (9,103 square kilometers) of Amazon rainforest were destroyed between August 2004 and July 2005, a marked decline from the 7,229 sq. mi. (18,723 sq. km.) in the same period a year earlier. While the government has tried to take credit for the drop, analysts say the slowing is more likely the result of lower commodity prices, giving farmers less incentive to clear forest land.


Brazil's growth as agricultural giant has cost -- LA Times

(08/22/2005) Saturday, the Los Angeles Times featured an article on Brazil's drive to become an agricultural giant. The country's breakneck growth has made it the world's biggest exporter of many agricultural products, but at a cost: some of Brazil's richest ecological areas have been plowed under for crops. Brazil has the highest biological diversity of any country on Earth.


Brazil's grasslands could replace food production of American heartland

(08/01/2005) 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.


Rainforest loss in the Amazon tops 200,000 square miles, new figures from Brazilian government

(05/20/2005) New figures from the Brazilian government show that 10,088 square miles of rain forest were destroyed in the 12 months ending in August 2004. Deforestation in the Amazon in 2004 was the second worst ever as rain forest was cleared for cattle ranches and soy farms.


Farmers and landless poor battle over the Amazon

(04/22/2005) Land battles in Brazil's countryside reached the highest level in at least 20 years in 2004 as activists clashed with farmers and loggers advancing on savanna and Amazon rain forest, a nongovernmental group said Tuesday.
