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

Extreme drought wrecks rivers and daily life in Amazon’s most burnt Indigenous land (Oct 18 2024)
- Almost 20% of the Kayapó Indigenous Territory has burned in this year’s Amazon drought, the worst ever recorded in Brazil.
- The land has for years been subjected to illegal mining, cattle ranching and burning of forests, degrading both the soil and rivers and significantly disrupting the way of life for the Mebêngôkre-Kayapó people.
- The Indigenous inhabitants now confront a growing crisis as wildfires and drought threaten their lands, particularly along the Riozinho River.
- According to ecologist Rodolfo Salm, who has worked with the Kayapó since 1996, fire has now surpassed illegal logging as the greatest danger to the region.

Rural-urban migration across the Amazon Basin (Oct 18 2024)
- After 2000, migration from rural to urban areas across the Pan Amazon intensified, as people started moving to either main urban centers or cities in the highlands or on coastlines.
- In Brazil, already by 2000, about 70% of the population was in urban centers. Most of the small and medium-size cities developed alongside extractive or agricultural activities doubled their population between 2000-2010.
- From the early 1990s to early 2000s, in the Colombian Amazon, civil violence boosted the movement of millions of people into cities, while the country’s peace agreement slowed down migration. But land grabbing and incoming rural investors could kickstart another urban population boom.

Amazon voters elect environmental offenders and climate denialists in Brazil (Oct 17 2024)
- The Amazonian population elected climate change deniers and politicians with a history of environmental fines to govern some of the region’s major cities.
- Pará’s state capital, Belém, which will host COP30 in 2025, may elect a mayor unconcerned about climate change.
- According to experts, opposing illegal activities is political suicide in municipalities whose economies rely on deforestation, illegal mining and illegal logging.

Delay of EU Deforestation Regulation may ‘be excuse to gut law,’ activists fear (Oct 17 2024)
- In a surprise move, the European Commission has proposed a 12-month delay in implementation of the EU’s groundbreaking deforestation law, which was slated to go into effect in January 2025.
- The European Parliament still needs to approve the delay, but is expected to do so. The law is meant to regulate global deforestation caused by a range of commodities from soy to coffee, cattle, cocoa, palm oil, rubber and wood products, including industrial-scale wood pellets burned to make energy.
- Commodity companies, including those in the pellet industry, say the law’s certification requirements are onerous and the 2025 start date is too soon for compliance. The industries are supported by commodities-producing nations such as Brazil, Indonesia and the United States (a primary source of wood pellets).
- Forest campaigners, including those opposing tree harvests for wood pellets, fear that delay of the EU Deforestation Regulation (EUDR) will offer commodity companies and exporting nations time to water down the law meant to protect native forests, carbon storage and biodiversity, and delay the worst climate change impacts.

Climate change and agrochemicals pose lethal combo for Amazonian fish (Oct 17 2024)
- A recent study evaluates the impacts on the Amazonian tambaqui fish from simultaneous exposure to a mix of pesticides and an extreme climate change scenario.
- Researchers subjected the fish to higher temperatures and higher atmospheric CO2 levels, as well as a cocktail of two pesticides, a herbicide and a fungicide, all of which are commonly used in farms throughout the Brazilian Amazon.
- The tambaqui’s capacity to metabolize the agrochemicals was found to be compromised in warmer water, and they suffered damage to their liver, nervous system and DNA.
- The study also points to the risks to food safety in the region, where fish are the main protein source: some 400 metric tons of tambaqui are eaten every year in the city of Manaus alone.

Brazil elects record-high number of Indigenous mayors, vice mayors & councilors (Oct 16 2024)
- In Brazil, 256 Indigenous people were elected mayors, vice mayors and city councilors, the highest in the country’s history and an 8% increase compared with 236 elected in the 2020 ballot.
- With 1,635,530 votes, Indigenous candidates were the only group that recorded growth in votes this year, compared with candidates who self-declared white, pardo (brown), Black and Asian, which saw a reduction of around 20% altogether, according to a survey from the Articulation of Indigenous Peoples of Brazil (APIB), the country’s main Indigenous association, which used data from the Superior Electoral Court (TSE).
- Increasing representation of Indigenous people elected in municipal ballots is a key move to ensure the fulfillment of Indigenous rights and should pave the way to increase the number of Indigenous people elected in the 2026 state and federal ballots, advocates and activists say.
- However, the municipal election results also showed a gender gap: Indigenous women accounted for just one mayor of a total of nine Indigenous mayors elected, four vice mayors of a total of nine, and 36 of a total of 234 councilors.

Act now or lose the Pantanal forever (commentary) (Oct 15 2024)
- This year, over two million hectares of the world’s largest wetland, the Pantanal in Brazil, have burned, as agribusiness drains it and climate change dries it, reducing river flows and allowing fires to spread.
- Many species rely on a healthy Pantanal to survive, including 2,000 species of plants, 580 bird species, 271 kinds of fish, and 174 mammal and 57 amphibian species, many of which are endangered or threatened.
- “To truly protect it, we need an immediate halt on further agricultural expansion, major restoration projects for the land which has already burned, and bold global action to slash carbon emissions,” a new op-ed argues.

Delays in land titling threaten the conservation success of quilombos in Brazil (Oct 15 2024)
- Titled quilombo territories — traditional Brazilian communities originally formed by runaway enslaved people — have significantly lower deforestation rates, making them crucial for conserving Brazil’s natural biomes.
- However, only 4.33% of all Quilombolas in Brazil have been granted proper land rights.
- Quilombola communities in Alcântara have fought for their land rights since the 1970s, facing displacement and government neglect, but the Brazilian Air Force is pushing for an expansion of the local space center, delaying the recognition of Quilombola land claims.
- Brazil has admitted to human rights violations against the Alcântara Quilombolas, but progress on land titling remains slow and uncertain.

Deforestation remains low, but fires surge in Brazil’s Amazon rainforest (Oct 12 2024)
- Deforestation in the Brazilian Amazon remains near a six-year low, with 561 square kilometers cleared in September, a 30% decline from the previous year.
- Fires in the Amazon have surged dramatically, with an 18-fold increase in the area affected by fires, from 4,700 to 39,983 square kilometers, driven by a historic drought.
- Fire hotspots detected by satellite in the Amazon increased by 70%, rising to 145,357 compared to 85,670 the previous year.
- Scientists warn that deforestation, forest degradation, and climate change could destabilize the Amazon, affecting rainfall patterns and biodiversity across South America.

‘World’s largest’ carbon credit deal in the Amazon faces bumpy road ahead (Oct 9 2024)
- The Brazilian state of Pará has agreed to sell millions of carbon credits to multinational corporations, including Amazon, Bayer and Walmart Foundation, but many challenges loom.
- Experts are concerned the deal is overly ambitious and worry about the state’s long history of carbon credit project scams.
- Although Indigenous, Quilombola and extractive community entities support the arrangement, other community members state they have not been consulted about the project on their lands.

Indigenous communities in the Amazon fight for full recognition (Oct 9 2024)
- Before the arrival of European colonizers, rural societies in the Amazon Basin domesticated plants and developed agricultural practices and infrastructure which provided supplies of food and fiber and improved crop yields.
- As missionaries and the expansion of trade brought pathogens into communities which lacked immunity, the number of Indigenous people across the Amazon dropped drastically in the fifteenth and sixteenth centuries, from an estimated 4 to 15 million people to about 400,000.
- In Brazil, a population census in the early 1990s showed an increase of Indigenous population, indicating higher birth rates and increased Indigenous self-identification. Boosting the latter across the Amazon Basin requires policies that prioritize the formalization of land rights of communities with specific ethnic heritage.

Prospect of mining is a bitter pill for Afro-Brazilian community known for its honey (Oct 8 2024)
- In northern Brazil’s Piauí state, the vast Afro-Brazilian enclave of Lagoas is home to 119 communities, making it the largest of its kind in the semiarid Caatinga biome and one of the region’s largest producers of organic honey.
- In 2019, the mining company SRN Mineração obtained a temporary permit to prospect for iron ore in the region, posing a threat to the communities’ beekeeping livelihoods as it could contaminate or destroy the bees’ food sources.
- Community leaders say they weren’t consulted by the mining company and that it continues to disrespect their presence and traditions by prospecting less than 100 meters (330 feet) from their most important shrine.

The people who make up the Pan-Amazonian melting pot: regional demographics (Oct 4 2024)
- Based on current trends, the Pan Amazon should have a total population of about sixty million by 2050 and stabilize at about 65 million by 2100.
- Currently, the Pan Amazon is home to approximately 43 million people. Of these, 80% are represented by immigrants or their descendants.
- Although there was a major population growth in the 1970s and 19880s, birth rates have been gradually decreasing and stabilzing.

New conservation model calls for protecting Amazon for its archaeological riches (Oct 4 2024)
- Across the Amazon, archaeological remains indicate that the human presence in the rainforest is much older, larger and more widespread than previously thought.
- Researchers in Brazil are lobbying to register archaeological sites as national monuments, which would confer a new layer of protection status to parts of the rainforest.
- Earthen mounds known as geoglyphs, for instance, have been revealed to stretch from Acre state north into neighboring Amazonas; formally recognizing them under Brazil’s heritage law could protect this vast swath of rainforest.
- “Today we know it’s highly likely that part of the forest has been changed by people,” said Dutch biologist Hans ter Steege, co-author of research that has shown there may be up to 24,000 earthworks hidden throughout the rainforest that could qualify for protection.

Brazil dredges Amazon rivers to ease drought isolation, raising environmental concerns (Oct 1 2024)
- Brazil has committed to dredge major Amazon rivers in response to record drought that has lowered water levels and made ship passage, a key transportation lifeline, difficult or impossible.
- The dredging is aimed at supporting local communities, who rely on river navigation to get supplies in from outside, and producers, who need to ship their commodities out.
- But experts question whether dredging is a sustainable solution, raising concerns about long-term ecological impacts and advocating for community involvement and innovative technology for better outcomes.
- The environmental risks of dredging include ecosystem disruption, increased erosion, water contamination, and harm to aquatic species such as manatees and river dolphins.

The Amazon is ablaze again. What it means for us (commentary) (Sep 30 2024)
- The Amazon rainforest, devastated by over 70,000 wildfires in 2019, is once again ablaze, threatening even greater destruction of wildlife, human health, and ecosystems.
- Climate change is now a tangible global threat, with rising sea levels and extreme heat affecting entire regions, while indigenous communities, like the Kogi in Colombia, have long warned of these environmental dangers, argues Mark J. Plotkin, an ethnobotanist who co-founded the Amazon Conservation Team.
- The Amazon, which stores one-fifth of the world’s terrestrial carbon, plays a crucial role in regulating global climate, but continued deforestation risks releasing this carbon and disrupting weather patterns far beyond the region.

Brazil’s race to approve the end of the Amazon: The BR-319 highway needs a new environmental impact assessment (commentary) (Sep 28 2024)
- Brazil’s race to approve “reconstruction” of Highway BR-319 (Manaus-Porto Velho) is gaining ever more momentum, with President Lula declaring his support for the project on the 10th September, a moment that could not be more ironic amid the country’s dramatic fire crisis, argues researcher Philip M. Fearnside in this commentary.
- The impact of BR-319 extends far beyond the roadside strip to which the EIA and licensing discussion is limited. Planned side roads such as AM-366 would open the vast rainforest area west of the highway to the entry of deforesters, loggers and others. The rainforest in this area is also at risk of collapse from climate change, and this risk would be further increased by the deforestation and forest degradation provoked by the planned roads linked to BR-319. Loss of this forest would be catastrophic both for global climate and for water supply to other parts of Brazil, including São Paulo.
- The area at risk is both the most critical and the easiest to avoid deforesting. All that needs to be done is to not build the highways that would provide access, while in other parts of Amazonia stopping deforestation requires changing the behavior of hundreds of thousands of individual actors. A new EIA is needed that includes all areas receiving impacts from BR-319 in the northern and western parts of Brazilian Amazonia. The EIA cannot be a mere bureaucratic step after which the project is automatically approved – the rational decision is to reject the project, writes Fearnside.

‘We need white men on our side to save the Amazon from destruction,’ 92-year-old Indigenous Chief Raoni says (Sep 26 2024)
- Indigenous leaders gathered at New York Climate Week to call on global leaders to address the unprecedented drought and wildfire crisis in the Amazon Rainforest.
- Chief Raoni Metuktire, a historic Indigenous leader of Brazil, asked non-Indigenous communities to reflect on their responsibility — mainly the introduction of illegal mining, logging and cattle ranching that are accelerating the impacts of climate change.
- Many Indigenous communities are in the path of wildfires, and isolated Indigenous peoples (PIA) are the most vulnerable.

Police murder Guarani man as Brazil struggles with Indigenous land demarcation (Sep 26 2024)
- Neri Ramos de Silva, a 23-year-old Guarani Kaiowá man, was shot in the back of the head by military police in the southwestern state of Mato Grosso do Sul, Brazil, where the Ñande Ru Marangatu territory overlaps with private property.
- The violence has refocused attention on the country’s slow land demarcation process and the unsafe conditions it has created for Guarani and other Indigenous people.
- The Guarani Kaiowá have been trying to demarcate their land since the early 2000s but ran into delays because of the “time frame” law, which only allows reclamation for Indigenous communities who were physically present on land as of 1988, when the new constitution restored democracy.

Why the Maxakali people are calling on their spirits to recover the Atlantic Forest (Sep 25 2024)
- Self-identified as Tikmũ’ũn, the Maxakali people now live in a small fraction of their original territory, which extended across the northeastern hills of Minas Gerais state.
- Confined to four small Indigenous reserves taken over by pasture, the Maxakali suffer from hunger, diseases and high mortality rates; they also lack the Atlantic Forest, essential for maintaining their rich and complex cosmology.
- To reverse deforestation and ensure food sovereignty, the Hãmhi project has been training Maxakali agroforestry agents to create agroforests and reforestation areas; the presence of the yãmĩyxop, the spirit-people, has been essential in this process.
