Deforestation in the Amazon
DEFORESTATION IN BRAZIL: 60-70 percent of deforestation in the Amazon results from cattle ranches while the rest mostly results from small-scale subsistence agriculture. Despite the widespread press attention, large-scale farming (i.e. soybeans) currently contributes relatively little to total deforestation in the Amazon. Most soybean cultivation takes place outside the rainforest in the neighboring cerrado grassland ecosystem and in areas that have already been cleared. Logging results in forest degradation but rarely direct deforestation. However, studies have showed a close correlation between logging and future clearing for settlement and farming.

Selective logging and fires that burn under the forest canopy commonly result in forest degradation, not deforestation. Therefore these factor less in overall deforestation figures.
The above pie chart showing deforestation in the Amazon by cause is based on the median figures for estimate ranges. Please note the low estimate for large-scale agriculture. Between 2000-2005 soybean cultivation reesulted in a small overall percentage of direct deforestation. Nevertheless the role of soy is quite significant in the Amazon. As explained by Dr. Philip Fearnside, "Soybean farms cause some forest clearing directly. But they have a much greater impact on deforestation by consuming cleared land, savanna, and transitional forests, thereby pushing ranchers and slash-and-burn farmers ever deeper into the forest frontier. Soybean farming also provides a key economic and political impetus for new highways and infrastructure projects, which accelerate deforestation by other actors."
Between May 2000 and August 2006, Brazil lost nearly 150,000 square kilometers of
forest—an area larger than Greece—and since 1970, over 600,000 square kilometers (232,000 square miles) of Amazon rainforest have been destroyed. Why is Brazil losing so much forest? What can be done to slow deforestation?
Why is the Brazilian Amazon being Destroyed?
In many tropical countries, the majority of deforestation results from the actions of poor subsistence cultivators. However, in Brazil only about one-third of recent deforestation can be linked to "shifted" cultivators. Historically a large portion of deforestation in Brazil can be attributed to land clearing for pastureland by commercial and speculative interests, misguided government policies, inappropriate World Bank projects, and commercial exploitation of forest resources. For effective action it is imperative that these issues be addressed. Focusing solely on the promotion of sustainable use by local people would neglect the most important forces behind deforestation in Brazil.
Brazilian deforestation is strongly correlated to the economic health of the country: the decline in deforestation from 1988-1991 nicely matched the economic slowdown during the same period, while the rocketing rate of deforestation from 1993-1998 paralleled Brazil's period of rapid economic growth. During lean times, ranchers and developers do not have the cash to rapidly expand their pasturelands and operations, while the government lacks funds to sponsor highways and colonization programs and grant tax breaks and subsidies to forest exploiters.
A relatively small percentage of large landowners clear vast sections of the Amazon for cattle pastureland. Large tracts of forest are cleared and sometimes planted with African savanna grasses for cattle feeding. In many cases, especially during periods of high inflation, land is simply cleared for investment purposes. When pastureland prices exceed forest land prices (a condition made possible by tax incentives that favor pastureland over natural forest), forest clearing is a good hedge against inflation.
Such favorable taxation policies, combined with government subsidized agriculture and colonization programs, encourage the destruction of the Amazon. The practice of low taxes on income derived from agriculture and tax rates that favor pasture over forest overvalues agriculture and pastureland and makes it profitable to convert natural forest for these purposes when it normally would not be so.
A Closer Look at Brazilian Deforestation
Today deforestation in the Amazon is the result of several activities, the foremost of which include:
Several factors have spurred recent Brazil's growth as a producer of beef:
CURRENCY DEVALUATION—The devaluation of the Brazilian real against the dollar effectively doubled the price of beef in reals and created an incentive for ranchers to expand their pasture areas at the expense of the rainforest. The weakness of the real also made Brazilian beef more competitive on the world market [CIFOR].
CONTROL OVER FOOT-AND-MOUTH DISEASE—The eradication of foot-and-mouth disease in much of Brazil has increased price and demand for Brazilian beef.
INFRASTRUCTURE—Road construction gives developers and ranchers access to previously inaccessible forest lands in the Amazon. Infrastructure improvements can reduce the costs of shipping and packing beef.
INTEREST RATES—Rainforest lands are often used for land speculation purposes. When real pasture land prices exceed real forest land prices, land clearing is a good hedge against inflation. At times of high inflation, the appreciation of cattle prices and the stream of services (milk) they provide may outpace the interest rate earned on money left in the bank.
LAND TENURE LAWS—In Brazil, colonists and developers can gain title to Amazon lands by simply clearing forest and placing a few head of cattle on the land. As an additional benefit, cattle are a low-risk investment relative to cash crops which are subject to wild price swings and pest infestations. Essentially cattle are a vehicle for land ownership in the Amazon.
Some have suggested that agricultural certification could help reduce destructive clearing for cattle pasture.
Poor farmers use fire for clearing land and every year satellite images pick up tens of thousands of fires burning across the Amazon. Typically understory shrubbery is cleared and then forest trees are cut. The area is left to dry for a few months and then burned. The land is planted with crops like bananas, palms, manioc, maize, or rice. After a year or two, the productivity of the soil declines, and the transient farmers press a little deeper and clear new forest for more short-term agricultural land. The old, now infertile fields are used for small-scale cattle grazing or left for waste.
Between 1995 and 1998, the government granted land in the Amazon to roughly 150,000 families. Forty-eight percent of forest loss in 1995 was in areas under 125 acres (50 hectares) in size, suggesting that both loggers and peasants are significant contributors to deforestation.
Philip Fearnside, co-author of a report in Science [21-May-04] and member of Brazil's National Institute for Amazonian Research in Manaus, explains,
"Soybean farms cause some forest clearing directly. But they have a much greater impact on deforestation by consuming cleared land, savanna, and transitional forests, thereby pushing ranchers and slash-and-burn farmers ever deeper into the forest frontier. Soybean farming also provides a key economic and political impetus for new highways and infrastructure projects, which accelerate deforestation by other actors."
Satellite data from 2004 shows a marked increase in deforestation along the BR-163 road, a highway the government has been paving in an effort to help soy farmers from Mato Grosso get their crops to export markets. Typically, roads encourage settlement by rural poor who look to the rainforest as free land for subsistence agriculture.
Other causes of forest loss in Brazil
Historically, hydroelectric projects have flooded vast areas of Amazon rainforest. The Balbina dam flooded some 2,400 square kilometers (920 square miles) of rainforest when it was completed. Phillip Fearnside, a leading expert on the Amazon, calculated that in the first three years of its existence, the Balbina Reservoir emitted 23,750,000 tons of carbon dioxide and 140,000 tons of methane, both potent greenhouse gases which contribute to global climate change.
Mining has impacted some parts of the Amazon Basin. During the 1980s, over 100,000 prospectors invaded the state of Para when a large gold deposit was discovered, while wildcat miners are still active in the state of Roraima near the Venezuelan border. Typically, miners clear forest for building material, fuelwood collection, and subsistence agriculture.
Fires and climate change are having a dramatic impact on the Amazon. Recent studies suggest that the Amazon rainforest may be losing its ability to stay green all year long as forest degradation and drought make it dangerously flammable. Scientists say that as much as 50 percent of the Amazon could go up in smoke should fires continue. Humidity levels were the lowest ever recorded in the Amazon in 2005.
Slavery and Violence in the Amazon
The Amazon has been a place of violence since at least the arrival of European explorers, and the present is no exception. Violent conflicts between large landowners, poor colonists, and indigenous groups over land are not unusual in the Amazon and may be worsening.
The Pastoral Land Commission, a nongovernmental group working in the region, found that land battles in Brazil's countryside reached the highest level in at least 20 years in 2004. According to the annual report by the organization, documented conflicts over land among peasants, farmers, and land speculators rose to 1,801 in 2004 from 1,690 conflicts in 2003 and 925 recorded in 2002. Tensions reached their peak earlier this year with the high-profile slaying of Dorothy Stang, an American nun who worked with rural poor, by gunmen associated with plantation owners. In response to the murder, the Brazilian government sent in the army to quell violence in the region and promised to step up environmental monitoring efforts.
The government has also stepped up efforts to end slavery in the Amazon. While Brazil officially abolished slavery in 1888, the government acknowledges that at least 25,000 Brazilians work under "conditions analogous to slavery," clearing land and working for cattle ranches, soy farms, and other labor-intensive industries. Some groups say the true figure could be ten times that amount. In 2005, 4,133 slaves were freed after Brazilian Swat-style teams raided 183 farms.
Brazil will forge its own path for developing the Amazon
(5/15/2008) The Brazilian government will use cheap loans, payments, and other benefits to encourage Amazon farmers to reduce their impact on the Amazon rainforest, under a plan unveiled last week
Convicted nun-killer freed in the Brazilian Amazon
(5/14/2008) Charges against a Brazilian rancher convicted of arranging the 2005 murder of a 73-year-old American nun in the Amazon rainforest have been dismissed.
After acquittal, fear of open season on activists in the Amazon rainforest
(5/14/2008) Bishop Flavio Giovenale was crushed by the acquittal last week of a rancher accused of ordering the killing of a crusading American nun — and not just because he admired Dorothy Stang. Giovenale, who spends much of his time battling child prostitution, police corruption and drug abuse, fears the verdict means it's open season again on activists in the Amazon jungle state of Para.
New species of river dolphin discovered in the Amazon
(4/30/2008) Researchers have identified a new species of river dolphin in the Bolivian Amazon according to the Whale and Dolphin Conservation Society (WDCS). The announcement was made at a conservation workshop in Santa Cruz de la Sierra in Bolivia.
Photos of newly discovered species in Brazil's Cerrado
(4/29/2008) 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.
No sacrifices to ending deforestation in the Amazon, only gains
(4/29/2008) Regular columnist and co-creator of Brazil's environmental news website, O Eco, Sergio Abranches has great credibility in Brazil's eco-awakening. A professor of political science, Abranches uses his unique talents to reach a widening audience in Brazil for environmental, energy, and climate change news and discussion. He speaks expertly on any number of topics: from Amazonian deforestation to the current food crises to economic and political transformations for a warming world.
'Soy King' says Amazon deforestation could help solve global food crisis
(4/28/2008) Clearing the Amazon rainforest for soy farms will help address the global food crisis, said Blairo Maggi, the governor of Brazil's chief soy-producing state, according to the Folha de Sao Paulo newspaper.
Brazil prepares to launch attack on NGOs working in the Amazon
(4/27/2008) Brazil is planning a crackdown on foreign NGOs working in the Amazon rainforest, reports Reuters. Tourists may also be required to inform officials of their travel plans in the region under the newly proposed rule.
Amazon farming technique may fight global warming
(4/11/2008) 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
(4/3/2008) 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
(4/3/2008) 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
(4/2/2008) 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.
Corn planting to drop 8% in 2008
(3/31/2008) The UDSA's National Agricultural Statistics Service (NASS) expects American farmers to plant 86 million acres of corn in 2008, down 8 percent from last year. The news comes amid record high prices for competitive crops including soybeans and wheat.
Private equity firm buys rights to ecosystem services of Guyana rainforest
(3/27/2008) 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.
