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.

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?
UPDATE: Future threats to the Amazon rainforest
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:
- Clearing for cattle pasture
- Colonization and subsequent subsistence agriculture
- Infrastructure improvements
- Commercial agriculture
- Logging
Clearing for Cattle Pasture
Cattle ranching is the leading cause of deforestation in the Brazilian Amazon. This has been the case since at least the 1970s: government figures attributed 38 percent of deforestation from 1966-1975 to large-scale cattle ranching. However, today the situation may be even worse. According to the Center for International Forestry Research (CIFOR), "between 1990 and 2001 the percentage of Europe's processed meat imports that came from Brazil rose from 40 to 74 percent" and by 2003 "for the first time ever, the growth in Brazilian cattle production—80 percent of which was in the Amazon—was largely export driven."
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.
Colonization and subsequent subsistence agriculture
A significant amount of deforestation is caused by the subsistence activities of poor farmers who are encouraged to settle on forest lands by government land policies. In Brazil, each squatter acquires the right (known as a usufruct right) to continue using a piece of land by living on a plot of unclaimed public land (no matter how marginal the land) and "using" it for at least one year and a day. After five years the squatter acquires ownership and hence the right to sell the land. Up until at least the mid-1990s this system was worsened by the government policy that allowed each claimant to gain title for an amount of land up to three times the amount of forest cleared.
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.
Infrastructure Improvements
Road construction in the Amazon leads to deforestation. Roads provide access to logging and mining sites while opening forest frontier land to exploitation by poor landless farmers.
Brazil's Trans-Amazonian Highway was one of the most ambitious economic development programs ever devised, and one of the most spectacular failures. In the 1970s, Brazil planned a 2,000-mile highway that would bisect the massive Amazon forest, opening rainforest lands to (1) settlement by poor farmers from the crowded, drought-plagued north and (2) development of timber and mineral resources. Colonists would be granted a 250-acre lot, six-months' salary, and easy access to agricultural loans in exchange for settling along the highway and converting the surrounding rainforest into agricultural land. The plan would grow to cost Brazil US$65,000 (1980 dollars) to settle each family, a staggering amount for Brazil, a developing country at the time.
The project was plagued from the start. The sediments of the Amazon Basin rendered the highway unstable and subject to inundation during heavy rains, blocking traffic and leaving crops to rot. Harvest yields for peasants were dismal since the forest soils were quickly exhausted, and new forest had to be cleared annually. Logging was difficult due to the widespread distribution of commercially valuable trees. Rampant erosion, up to 40 tons of soil per acre (100 tons/ha) occurred after clearing. Many colonists, unfamiliar with banking and lured by easy credit, went deep into debt.
Adding to the economic and social failures of the project, are the long-term environmental costs. After the construction of the Trans-Amazonian Highway, Brazilian deforestation accelerated to levels never before seen and vast swaths of forest were cleared for subsistence farmers and cattle-ranching schemes. The Trans-Amazonian Highway is a prime example of the environmental havoc that is caused by road construction in the rainforest.
Road construction and improvement continues in the Amazon today: Paving of roads brings change in the Amazon rainforest and the Chinese economy drives road-building and deforestation in the Amazon
Commercial agriculture
Recently, soybeans have become one of the most important contributors to deforestation in the Brazilian Amazon. Thanks to a new variety of soybean developed by Brazilian scientists to flourish in rainforest climate, Brazil is on the verge of supplanting the United States as the world's leading exporter of soybeans. High soybean prices have also served as an impetus to expanding soybean cultivation.
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.
Logging
In theory, logging in the Amazon is controlled by strict licensing which allows timber to be harvested only in designated areas. However, there is significant evidence that illegal logging is quite widespread in Brazil. In recent years, Ibama—Brazil's environmental enforcement agency—has made several large seizures of illegally harvested timber including one in September 2003 when 17 people were arrested for allegedly cutting 10,000 hectares worth of timber.
Logging in the Amazon is closely linked with road building. Studies by the Environmental Defense Fund show that areas that have been selectively logged are eight times more likely to be settled and cleared by shifting cultivators than untouched rainforests because of access granted by logging roads. Logging roads give colonists access to rainforest, which they exploit for fuelwood, game, building material, and temporary agricultural lands.
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
Virtually all forest clearing, by small farmer and plantation owner alike, is done by fire. Though these fires are intended to burn only limited areas, they frequently escape agricultural plots and pastures and char pristine rainforest, especially in dry years like 2005. Many of the fires set for clearing forest for these purposes are set during the three-month burning season and the smoke produced creates widespread problems across the region, including airport closings and hospitalizations from smoke inhalation. These fires cover a vast area of forest. In 1987 during a four-month period (July-October), about 19,300 square miles (50,000 sq. km) of Brazilian Amazon were burned in the states of Parà, Rondonia, Mato Grosso, and Acre. The burning produced carbon dioxide containing more than 500 million tons of carbon, 44 million tons of carbon monoxide, and millions of tons of other particles and nitrogen oxides. An estimated 20 percent of fires that burn between June and October cause new deforestation, while another 10 percent is the burning of ground cover in virgin forests.
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.
