Brazil's forests

By Rhett A. Butler [Last update August 14, 2020]

Brazil holds about one-third of the world's remaining primary tropical rainforests, including about 60% the Amazon rainforest. Terrestrially speaking, it is also the most biodiverse country on Earth, with more than 34,000 described species of plants, 1,813 species of birds, 1,022 amphibians, 648 mammals, and 814 reptiles.

About 80% of Brazil's tropical forest cover is found in the Amazon Basin, a mosaic of ecosystems and vegetation types including rainforests (the vast majority), seasonal forests, deciduous forests, flooded forests, and savannas, including the woody cerrado. This region has experienced an exceptional extent of forest loss over the past two generations—an area exceeding 760,000 square kilometers, or about 19 percent of its total surface area of 4 million square kilometers, has been cleared in the Amazon since 1970, when only 2.4 percent of the Amazon's forests had been lost. The increase in Amazon deforestation in the early 1970s coincided with the construction of the Trans-Amazonian Highway, which opened large forest areas to development by settlers and commercial interests. In more recent years, growing populations in the Amazon region, combined with increased viability of agricultural operations, have caused a further rise in deforestation rates.

This data excludes extensive areas degraded by fires and selective logging, nor forest regrowth, which by one Brazilian government estimate occurs on about 20% of deforested areas. The area of Amazon forest degraded each year in Brazil is thought to be roughly equivalent to the amount of forest cleared. Forest degradation is significant because degraded forests are more likely to be cleared in the future. Degraded forest is also more susceptible to fires.

Why is the Amazon rainforest disappearing?

Historically the majority of deforestation in the Brazilian Amazon was the product of subsistence farmers, but in recent decades this has changed, with a greater proportion of forest clearing driven by large landowners and corporations. The majority of deforestation in the region can be attributed to land clearing for pasture by commercial and speculative interests.

In the early phase of this transition, Brazilian deforestation was 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 expand their pasturelands and operations, while the government lacks the budget flexibility to underwrite highways and colonization programs and grant tax breaks and subsidies to agribusiness, logging, and mining interests.

But this dynamic shifted in the mid-2000s, when the link between deforestation and the broader Brazilian economy began to wane. Between 2004 and 2012 the annual rate of deforestation in the Brazilian Amazon fell 80% to the lowest levels recorded since annual record keeping began in the late 1980s. This decline occurred at the same time that Brazil's economy expanded 40 percent and agricultural output surged.

Why did Amazon deforestation decline?

There are several reasons commonly cited for the decline in Brazil's deforestation rate between 2004 and 2012.

One of the most important active measures was the launch of the Action Plan for the Prevention and Control of Deforestation in the Legal Amazon (PPCDAm) in 2004. PPCDAm aimed to reduce deforestation rates continuously and facilitate conditions that support a transition towards a sustainable economic development model in the region. PPCDAm had three main components: land tenure and spatial planning, environmental monitoring and control, and supporting sustainable production.

These components resulted in increased enforcement of environmental laws; improved forest monitoring by satellite, which enabled law enforcement to take action; new incentives for utilizing already deforested lands; and expanded protected areas and indigenous reserves. A byproduct of PPCDAm was heightened sensitivity to environmental criticism among private sector companies and emerging awareness of the values of ecosystem services afforded by the Amazon.

Other factors also played a part in the decline in deforestation, including macroeconomic trends like a stronger Brazilian currency, which reduced the profitability of export-driven agriculture; prioritization of non-rainforest areas like the adjacent cerrado ecosystem for agribusiness expansion; and increased diversification in the Brazilian economy as a whole.

Why has progress in reducing Amazon deforestation stalled?

Progress in reducing deforestation stalled after 2012 and forest loss has been trending upward since. There is debate over why this is the case, but some researchers argue that Brazil achieved about as much as it could through law enforcement and other punitive measures ("the stick" in the proverbial "the carrot and stick" approach). Reducing deforestation further requires sufficient economic incentives ("the carrot") to maintain forests as healthy and productive ecosystems. Put another way, standing forest needs to be made more valuable than clearing it for pasture or crops.

By that line of thought, the political impetus for reducing deforestation began to wane as ranchers, farmers, investors, and land speculators grew tried of fines, threats of legal action, and prohibitions against clearing. Political movements like the ruralistas pushed harder for relation of environmental laws and amnesty for past transgressions. These interests gained momentum when the Temer administration came to power in 2016 and won more clout with the election of Jair Bolsonaro in late 2018. Bolsonaro, who campaigned on the promise to open the Amazon to extractive industries and agribusiness while disparaging environmentalists and indigenous peoples, immediately set about dismantling protections for the Amazon when he took office in January 2019. Deforestation increased sharply thereafter.

Causes of deforestation in the Amazon

In evaluating deforestation in the Amazon, it is important to understand both direct and indirect drivers of forest loss.

Direct drivers of deforestation including conversion of forests for pasture, farmland, and plantations, as well as surface mining, dams that inundate forested areas, and intense fires.

Indirect drivers of deforestation include more subtle factors, like insecure land tenure, corruption, poor law enforcement, infrastructure projects, policies that favor conversion over conservation, and selective logging that create conditions or enable activities that facilitate forest clearing.

Cattle ranching

Conversion of rainforest for cattle pasture is the single largest driver of deforestation in Brazil. Clearing forest for pasture is the cheapest and easiest way to establish an informal claim to land, which can then be sold on to other parties at a profit. In some parts of the Brazilian Amazon, cleared rainforest land can be worth more than eight times that of land with standing forest. According, cattle ranching is often viewed as a way to speculate on appreciating land prices.

However since 2000, cattle ranching in the Amazon has become increasingly industrialized, meaning that more ranchers are producing cattle to sell commercially. Most of the beef ends up in the domestic market, but secondary products like hides and leather are often exported.

These exports left Brazilian cattle ranchers exposed in the late 2000s when Greenpeace launched a high profile campaign against companies that were sourcing leather and other products from major Brazilian cattle processors. That campaign led major companies to demand zero deforestation cattle. Combined with a crackdown by public prosecutors, the Brazilian cattle industry started to shift substantially toward less damaging practices in late 2009 by signing the "Cattle Agreement", which barred the sourcing of cattle from illegally deforested areas.

However by the mid-2010s investigations revealed that some major cattle producers were circumventing the safeguards established under the Cattle Agreement by laundering cattle through third party ranches. Unlike soy (see below), cattle are highly mobile, making it easy for ranchers to shift livestock clandestinely.

Soy

The model for the Brazilian cattle industry to move toward zero deforestation came from the country's soy industry, which underwent a similar transformation three years earlier. That shift was also initiative by a Greenpeace campaign, which targeted the soy-based chicken feed used by McDonald's in Europe. Within months of that campaign's launch, the largest soy crushers and traders in the Amazon had established a moratorium on buying soy produced via deforestation in the Amazon.

Timber

Logging in the Brazilian Amazon remains plagued by poor management, destructive practices, and outright fraud. Vast areas of rainforest are logged -- legally and illegally -- each year. According to government sources and NGOs, the vast majority of logging in the Brazilian Amazon is illegal.

Palm oil

At present, Amazon palm oil is not a major driver of deforestation in Brazil. While there are concerns that it could eventually exacerbate deforestation, there is also a chance that it could replace degraded cattle pasture, boosting economic productivity at a low environmental cost.

Dams, roads, and other infrastructure projects

Brazil's infrastructure spree from the late-2000s to mid-2010s was interrupted by the corruption scandals of the mid-2010s. Many of the scores of dams being built across the Amazon basin were put on hold following the Lava Jato scandal that ensnared senior politicians in several countries and executives at the infrastructure giant Odebrecht. Yet the scandals also helped usher in the presidency of Jair Bolsonaro, which reinvigorated the push to build roads, dams, and mines in the Amazon.

Conservation in Brazil

While Brazil may be better known for losing its forests, during the 2000s it easily led the world in establishing new protected areas. Those gains were consolidated in 2014, when donors established a trust fund that will underwrite the country's protected areas system through 2039.

Beyond strict protected areas, more than a fifth of the Brazilian Amazon lies within indigenous reservations, which research has shown reduce deforestation even more effectively than national parks. Overall nearly half the Brazilian Amazon is under some form of protection.

Brazil's other forests

While the Amazon rainforest is Brazil's most famous forest, the country also has other types of forest.

The Mata Atlântica or Atlantic Forest is a drier tropical forest that lies along the coast and inland areas to the south of the Amazon. It has been greatly reduced by conversion to agriculture -- especially sugar cane and cattle pasture -- and urbanization. The Mata Atlântica is arguably Brazil's most threatened forest.

The Pantanal is an inland wetland that borders Paraguay and Bolivia and covers an area of 154,884 square kilometers. It includes a mosaic of forests and flooded grasslands.

The cerrado biome is a tropical grassland that covers 1.9 square kilometers, or approximately 22 percent of the country. It is being rapidly destroyed for agriculture.

The chaco biome is a dry forest ecosystem that extends into Paraguay, Bolivia, and Argentina.

Recent news on Brazil's tropical forests

Fires surge in the Amazon, but deforestation continues to fall (Mar 17 2024)
- Deforestation in the Brazilian Amazon has continued on a downward trajectory despite a sharp increase in fires associated with the severe drought in the region.
- According to data published by Brazil’s National Space Research Institute (INPE) earlier this month, forest loss in the Brazilian Amazon amounted to 5,010 square kilometers over the past twelve months, the lowest level recorded since May 2019.
- Despite the declining rate of forest loss, fires in the Amazon are on the rise, driven by the severe drought gripping the region.
- Deforestation in the Brazilian Amazon has fallen precipitously since Luiz Inácio Lula da Silva replaced Jair Bolsonaro as president last year.

Reforestation and restoration: Two ways to make the Pan Amazon greener (Mar 14 2024)
- Mongabay is publishing a new edition of the book, “A Perfect Storm in the Amazon,” in short installments and in three languages: Spanish, English and Portuguese.
- Efforts to save agroforestry zones require long-term patience and heavy investment, but ensure that plantations sequester up to 20% of the carbon stored in a natural forest, and even more carbon can be retained through natural habitat restoration.
- Killeen explains that tropical areas need to retain around 70% of their canopy cover to maintain the atmospheric recycling that sustains historical rainfall levels. In the southern Amazon, this would need to be applied to 15 million hectares with an investment of between $20 and $100 billion.
- For the author, these issues are all the more urgent as the threat of climate change is accelerating the Pan-Amazonian region to an irreversible tipping point. Are carbon markets providing incentives that ‘reward’ conservation in the Pan-Amazonian region?

Reconciling conservation agriculture and agroforestry for sustainability (Mar 13 2024)
- Mongabay is publishing a new edition of the book, “A Perfect Storm in the Amazon,” in short installments and in three languages: Spanish, English and Portuguese.
- In this section, Killeen focuses on land management that seeks to reconcile the technologies of modern agriculture with the worn-out practices of organic farming.
- It also analyzes the case of livestock farmers, who are not as likely to change their land management practices, as they have an underutilized surplus that has suffered from mismanagement.
- For Killeen, smallholder farmers should be more willing to diversify such production systems and adopt practices that increase resilience. Because mitigating risk is essential to their livelihoods: without crops comes bankruptcy and hunger. This is the case in countries such as Ecuador and Peru, where smallholder farmers occupy more than 90% of previously deforested areas.

Land irrigation as an obstacle to agricultural intensification in Mato Grosso (Mar 6 2024)
- Mongabay is publishing a new edition of the book, “A Perfect Storm in the Amazon,” in short installments and in three languages: Spanish, English and Portuguese.
- In this section, Killeen looks at industrialized crops in Brazil, specifically in Mato Grosso, where irrigation is expected to be heavily impacted by decreasing rainfall as a result of climate change and deforestation.
- The outlook over the next few years is grim. While current extraction levels are within parameters, the effective expansion rate of 10% per year will eventually outstrip surface water supplies, increasing demand for groundwater.
- According to studies conducted in Mato Grosso, the combined surface and groundwater resources could support 3.9 million hectares of agriculture.

What is most convenient in land distribution? (Mar 5 2024)
- Mongabay is publishing a new edition of the book, “A Perfect Storm in the Amazon,” in short installments and in three languages: Spanish, English and Portuguese.
- Predictions indicate that an ecological tipping point will be crossed when 25% of the Amazon’s forests will have been converted to agriculture, just a few percentage points from the current 18%. How can deforestation be halted?
- There are two approaches taken by specialists and academics: the savings approach, which involves using technology to intensify production on the land; and the sharing approach, which seeks to diversify production systems.
- For Killeen, both approaches could be applicable but their social, economic and environmental impacts will vary dramatically depending on where they are applied and on what scale.

Major meatpackers are unlawfully deforesting Brazil’s Cerrado, report says (Feb 29 2024)
- In the state of Mato Grosso, some of the country’s largest meatpackers are clearing parts of the Cerrado at an even faster rate than the Amazon Rainforest, a new report from U.K.-based NGO Global Witness says.
- Meatpackers JBS, Marfrig and Minerva have cut down nearly five times more of the state’s Cerrado than they have its Amazon. One in three cows that the companies purchased from the Cerrado had grazed on illegally deforested land.
- A major EU law regulating deforestation in supply chains is scheduled for review this year, and the Global Witness report said its language should be expanded to include “other wooded land” that would protect the Cerrado.

To reverse deforestation and protect biodiversity, build a bioeconomy in the Amazon (commentary) (Feb 23 2024)
- Slowing and reversing deforestation and land degradation in the Amazon requires not only conservation efforts but also increasing the economic value of standing primary forests through a bioeconomy approach, argues Robert Muggah, co-founder of Instituto Igarapé.
- A bioeconomy involves regenerative agriculture, sustainable energy, and other activities that leverage the forest’s natural assets while ensuring economic benefits for local communities. However, the expansion of the bioeconomy faces challenges, including resistance from extractive sectors, investment risks, and the need for infrastructure, research, and support for local enterprises.
- Despite these hurdles, advancing the bioeconomy is essential for sustainable development and decarbonization in the Amazon and crucial for the world, says Muggah.

Land use planning helps advance conservation in Brazil (Feb 21 2024)
- Mongabay is publishing a new edition of the book, “A Perfect Storm in the Amazon,” in short installments and in three languages: Spanish, English and Portuguese.
- In addition to regulating land tenure, land-use zoning and planning have been used across the Amazon Basin, as countries have aimed to protect forests and prevent the encroachment of agricultural frontiers.
- In Brazil,the Zonificación Ecológica Económica (ZEE) coincided with a parallel effort to protect large swathes of the Amazon and provided technical criteria and legal support for the creation of dozens of conservation units and Indigenous territories.

Brazil’s BR-319 highway: The danger reaches a critical moment (commentary) (Feb 17 2024)
- A project to rebuild Brazil’s notorious BR-319 highway is quickly moving closer to becoming a fait accompli. Together with planned side roads, BR-319 would open vast areas of Amazon rainforest to the entry of deforesters. A working group convened by the Ministry of Transportation will soon release a report intended to justify approval of the project’s environmental license. Congressional approval of legislation to force granting the license is also looming.
- Despite a constant political discourse claiming that governance will contain deforestation and tourists will admire the forest from their cars as they drive on a “park road,” the reality on an Amazon frontier is very different. Most of what happens once access is provided by road is outside of the government’s control.
- The consequences of unleashing deforestation in the last great block of Amazon forest would be catastrophic for Brazil, threatening the water carried to São Paulo by the winds known as “flying rivers” and pushing global warming past a tipping point.

In Brazil’s soy belt, community seed banks offer hope for the Amazon (Feb 15 2024)
- In Brazil’s state of Mato Grosso, monoculture has replaced large swathes of the Amazon rainforest and ushered in changes in climate patterns, including severe droughts and scarce rains, according to climate experts.
- Traditional and Indigenous peoples are looking to counter the impacts of large-scale soy plantations in the region by setting up community seed banks and reforesting degraded lands with species native to the Amazon.
- Experts say seed initiatives could play a key role in restoration efforts as Brazil scrambles to rehabilitate 60,000 square kilometers (23,160 square miles) of deforested land by 2030 and agribusiness faces global demands to reverse the damage it has inflicted on the Amazon.
- Seed banks could also help restore the biodiversity being lost in the Amazon, preserve species central to Indigenous cultures, and mitigate climate change, locally and globally.

Brazil’s 2024-2027 “Transversal Environmental Agenda”: The elephants in the room (commentary) (Feb 4 2024)
- Brazil’s current 4-year development plan is accompanied by a “Transversal Environmental Agenda,” released last week, to coordinate environmental measures across the different federal agencies.
- While the agenda lists many worthwhile items in the portfolios of the various ministries, it fails in the most basic role such an agenda should play: ensuring that government actions do not cause environmental catastrophes.
- Missing subjects include foregoing building roads that open Amazon forest to deforestation, legalizing illegal land claims that stimulates an unending cycle of land grabbing and invasion, plans for hydroelectric dams in Amazonia, expanding oil and gas drilling and the burning of fossil fuels that must end without delay if global warming is to be controlled.

Grassroots efforts and an Emmy-winning film help Indigenous fight in Brazil (Jan 29 2024)
- The 2022 documentary “The Territory” won an Emmy award this January, shining a light on the Uru-eu-wau-wau Indigenous people and the invasions, conflicts and threats from land grabbers in their territory in the Brazilian Amazon from 2018 to 2021.
- After years of increasing invasions and deforestation in the protected area, experts say the situation has slowly improved in the past three years, and both Indigenous and government officials in the region “feel a little safer.”
- Grassroots surveillance efforts, increased visibility of the problems, and a more effective federal crackdown against invaders have helped tackle illegal land occupiers and allowed the Indigenous populations to take their land back.
- Despite the security improvements, however, the territory still struggles against invasions and deforestation within the region, experts say.

Why the Amazon’s small streams have a major impact on its grand rivers (Jan 18 2024)
- An unprecedented time-series study in the basin of the Tapajós River, a major tributary of the Amazon, assesses the level of degradation of small rivers threatened by agribusiness expansion.
- Researchers from several universities will assess the conservation status of 100 streams spread between the municipalities of Santarém and Paragominas, at the confluence of the Tapajós and the Amazon, which were first analyzed in 2010.
- The impact of dirt roads and their network of river crossings, which causes sediment load, siltation, erosion and changes in water quality, was one of the factors that caught researchers’ attention in the initial time-series study.
- Experts say that local development models should ideally start from water to land, rather than the other way around, given the importance of water for the rainforest, its biodiversity, and the inhabitants who depend on both.

Amazonia in flames: Unlearned lessons from the 2023 Manaus smoke crisis (commentary) (Jan 17 2024)
- In 2023 the city of Manaus, in central Amazonia, found itself covered in dense smoke from burning rainforest, with levels of toxic PM 2.5 particulates even higher than those experienced that year during the pollution crisis in New Delhi, India.
- The governor of Brazil’s state of Amazonas, where Manaus is located, blamed the neighboring state of Pará for the smoke, a politically convenient theory we show to be false.
- The fires responsible for the smoke were south of Manaus in an area of Amazonas impacted by the notorious BR-319 highway, where a proposed “reconstruction” project would have disastrous environmental consequences by opening vast areas of rainforest to the entry of deforesters.The BR-319 highway project is a top priority for politicians in Amazonas, who take pains not to admit to the project’s impacts. The project’s environmental license is not yet approved, and the Manaus smoke crisis should serve as a warning as to how serious those impacts would be.

Thousands of tree species at risk of extinction in Atlantic Forest: study (Jan 16 2024)
- A study published in Science found that two-thirds of the populations of all 4,950 tree species that make up the Atlantic Forest are threatened with extinction.
- The Atlantic forest, which stretches along Brazil’s southern Atlantic coast, has experienced severe deforestation over recent decades due to expanding cities and agriculture, a result of more than 70% of the Brazilian population living in and around the forest.
- The researchers hope that some of the tree species will be included or updated in the IUCN Red List, which tracks the conservation status of flora and fauna. That could make it easier to develop future conservation strategies.
