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.

Brazil’s illegal gold miners carve out new Amazon hotspots in conservation units (Dec 20 2024)
- President Luiz Inácio Lula da Silva’s administration reduced the expansion of illegal gold mining in the Brazilian Amazon, but miners keep finding new sites.
- In 15 conservation units, illegal gold miners destroyed 330 hectares (815 acres) in only two months.
- According to experts, gold miners expelled from Indigenous territories may be migrating to conservation units.
- Alliances with narco mafias and the rise in gold prices are obstacles to fighting illegal mining.

Unlike: Brazil Facebook groups give poachers safe space to flex their kills (Dec 19 2024)
- A new study shows how openly poachers in Brazil are sharing content of dead wildlife, including threatened and protected species, on Facebook.
- It found 2,000 records of poaching on Brazilian Facebook groups between 2018 and 2020, amounting to 4,658 animals from 157 species from all over the country.
- Data suggest there were trophy hunts, meant only to show off hunting hauls rather than being done for subsistence or a consequence of human-wildlife conflict.
- The study highlights the impunity for environmental crimes and the easy dissemination of content related to illegal practices on social media networks in Brazil.

New frog species show how geology shapes Amazon’s biodiversity (Dec 19 2024)
- DNA testing of two new-to-science frog species has shown they share a common ancestor — a species that lived 55 million years ago in the mountains of what is today Brazil’s Amazonas state.
- The multidisciplinary study drew together biologists and geologists to map how geological changes in the mountain range shaped not just its geography but also the diversity of species in the region.
- The two endemic species were collected on two separate peaks — Neblina and Imeri — and their discovery has led to further understanding of the origins and evolution of biodiversity in the Amazon.
- Another expedition to the Tulu-Tuloi Range, located 200 kilometers (120 miles) from Imeri, is scheduled for 2025.

Brazil paper and pulp industry invests in blockchain to comply with EUDR (Dec 16 2024)
- Brazil’s paper and pulp industry says the European Union’s deforestation-free products regulation (EUDR), which will come into effect in late 2025, won’t affect the sector’s operations, which has already traced its supply chains “from farm to factory” for more than two decades and doesn’t source from illegal deforested areas.
- The EUDR will require suppliers to prove that their products exported to the EU aren’t sourced from illegally deforested areas; in Brazil, experts say it will help halt illegal deforestation in the Amazon.
- To fulfill some specific EUDR requirements, companies need to invest in blockchain and other technologies, which could increase the cost per ton of pulp by up to $230, according to the Brazilian Tree Industry (Ibá).
- The EUDR postponement was received differently by the industry and experts: While Ibá says it would allow “a smoother and more effective implementation,” given some aspects that need improvement from the EU Commission, deforestation experts say there is no time to wait, as deforestation continues and the climate crisis gets worse.

Illegal timber from Amazon carbon credit projects reached Europe, U.S. (Dec 16 2024)
- Amazon timber from carbon credit projects targeted by the Brazilian Federal Police was sold to companies in Europe and the United States.
- The group is suspected of land-grabbing and laundering timber from Indigenous territories and protected areas.
- Most of the exported timber belongs to the almost-extinct ipê species and was sent to a company in Portugal.
- The group is also suspected of using fake documents to launder cattle raised in illegally deforested areas.

Recycling gold can tackle illegal mining in the Amazon, but is no silver bullet (Dec 13 2024)
- Artisanal and small-scale gold mining in Brazil’s Tapajós River Basin emits 16 metric tons of CO2 per kilo of gold produced, and 2.5 metric tons of mercury annually, a study has found.
- Researchers suggest that recycling gold could dramatically reduce harmful emissions, along with other solutions such as formalizing mining, adopting clean technologies, and improving gold supply chain transparency.
- Economic dependence, mercury accessibility, and a demand for gold sustain small-scale gold mining, while enforcement risks pushing miners into ecologically sensitive areas.
- In November, Brazil launched a federal operation in the Tapajós Basin to expel illegal gold miners from the Munduruku Indigenous Territory, imposing millions of reais in fines to curb the damage caused by gold mining.

Communities warn of threat to ecosystems from Brazil bridge project (Dec 12 2024)
- Islanders and experts have warned of widespread environmental and social impacts from the construction of a bridge linking the Brazilian city of Salvador with the island of Itaparica in Todos os Santos Bay.
- Critics say the project will devastate mangrove forests and coral reefs, leading to environmental imbalance, compromising fishing communities and threatening the survival of many marine species including humpback whales and sea turtles.
- Proponents say the bridge will boost development in the region, in particular transporting agricultural produce, but islanders say the anticipated population surge on Itaparica will create unsustainable pressure on public services as well as drastically change the dynamics of the community living there.
- Experts say the best solution for improving transportation links between Salvador and Itaparica is to invest in the existing ferry system, but this option wasn’t considered by planners.

Brazil natural landscape degradation drives toxic metal buildup in bats (Dec 11 2024)
- Bats play a crucial role in tropical regions as pollinators, seed dispersers and agricultural pest controllers. But they are exposed to a wide range of threats, pollution among them.
- Two recent papers show how natural landscape transformation and degradation, due to pasture and crop monoculture creation and mining in Brazil’s Atlantic Forest, can increase bioaccumulation of toxins and heavy metals in bat populations, leading to potential health impacts.
- Over time, this toxic accumulation could increase the likelihood of local bat extinctions and the loss of vital ecosystem services. The toxic contamination of these landscapes also poses a concern for human health, researchers say.
- These findings are likely applicable to bats living in other highly disturbed tropical habitats around the world, researchers say.

Loggers and carbon projects forge odd partnerships in the Brazilian Amazon (Dec 9 2024)
- Mongabay examined four REDD+ projects in Pará state and found that all were developed in partnership with sawmill owners with a long history of environmental fines.
- The projects were developed by Brazil’s largest carbon credit generator, Carbonext, a company linked to a major fraud involving REDD+ projects and illegal loggers in Amazonas state.
- According to experts, REDD+ projects may have become a new business opportunity for individuals who have profited from deforestation for decades.

The uncertain future of Amazon river dolphins amid historic drought (Dec 6 2024)
- This year, the drought in Amazon rivers is already worse than in 2023, when 209 pink and grey river dolphins were found dead in Lake Tefé, in Amazonas state, largely due to overheating of the waters.
- To avoid a new tragedy, local organizations have taken action in advance, establishing emergency operations with stronger monitoring, staff training and equipment acquisition.
- However, no dolphin deaths due to heat stress have been recorded this year; instead, dozens of carcasses of aquatic mammals have appeared in Amazon lakes as a result of another sinister effect of drought: increased interactions with humans.

Pesticide exposure drives up rural women’s cancer risk in Brazil farming belt (Dec 5 2024)
- A study has found that women exposed to pesticides during farm work in Brazil’s Paraná state have a 60% higher risk of developing breast cancer, and a 220% higher risk of metastasis.
- While they don’t typically spray the pesticides, these women are responsible for cleaning the equipment and clothing used to do it, during which they rarely wear personal protective equipment.
- The study found glyphosate, atrazine and 2,4-D in urine samples from rural women; health and regulatory agencies consider these three pesticides as possibly or probably carcinogenic.
- Brazil has one of the most permissive pesticide markets in the world, where levels of exposure to chemicals like glyphosate are several times higher than in more strictly regulated jurisdictions such as the European Union.

Certified ethanol produced in Brazil for global airlines linked to slave labor (Dec 5 2024)
- Fuel produced from sugarcane in Brazil has become a strategic option for decarbonizing the aviation sector.
- But companies operating in this business have been linked to recent reports of labor abuses on sugarcane farms, a new report from Repórter Brasil shows. The rise in reports of labor abuses is partly attributed to the growing outsourcing of labor for planting.
- Workers hired via subcontractors lived in poor conditions without basic amenities, traveled long hours to reach the sugarcarne fields, and paid for their safety equipment.
- While certifications needed to access the fuel market are meant to protect workers, experts says certifiers are not doing enough to ensure fair working conditions and pay.

‘Trump is a disease’, says Yanomami shaman Davi Kopenawa (Dec 2 2024)
- In addition to being a shaman, Davi Kopenawa is a shaman and a political leader active in denouncing the gold miners who illegally invaded the Yanomami Indigenous Land, in the Brazilian Amazon.
- The Yanomami, who inhabit Brazil’s largest Indigenous Land, still face a humanitarian and health crisis, worsened by the invasion of 70,000 illegal miners. Increased under the Jair Bolsonaro government, the invasion brought diseases and contaminated rivers with mercury. 
- In this interview, Kopenawa criticizes the environmental and social impacts of administrations led by politicians such as Jair Bolsonaro and Donald Trump.

In Brazil’s ‘water tank’, communities resist mining to preserve their water and livelihoods (Nov 30 2024)
- For more than fifteen years, traditional communities in Serro, Minas Gerais, have resisted the entry of iron ore mining on their territories.
- Serro is located in a region where several major rivers meet; the integrity of ecosystems is vital for people’s water resources and food security.
- Activists fear that, if approved, iron ore projects will not only cause irreversible socioenvironmental impacts but set a precedent for a dangerous iron ore race in Serro. Besides iron ore, the area concentrates deposits of bauxite, manganese, quartzite, and other minerals – many located next to traditional communities.
- The two companies pursuing mining in the area have had their licensing processes suspended in October 2023 after a community appeal to the Federal Court of Minas Gerais. The entities are required to carry out consultations with communities, respecting the principle of free, prior and informed consent.

Fires rip through Indigenous territories in Brazilian Amazon (Nov 29 2024)
- Xingu Indigenous Park and Capoto/Jarina Indigenous Territory in Brazil cover an area larger than Belgium.
- The Indigenous territories are still largely covered in primary forest, and a haven for wildlife in a region considered an agricultural powerhouse.
- Satellite data show Xingu Indigenous Park lost 15% of its primary forest cover, and Capoto/Jarina Indigenous Territory lost 8.3% of its forest cover, between 2002 and 2023.
- Indigenous groups fear proposed transportation projects will bring a fresh wave of deforestation and open up their territories to invaders.

Brazil plans new reserves to curb deforestation near contested Amazon roads (Nov 28 2024)
- Unallocated public areas account for 28% of deforestation in the Brazilian Amazon, and the destruction of these lands keeps rising even as rates plummet across other parts of the rainforest.
- To tackle the problem, Brazil’s federal government plans to convert lands around controversial Amazonian highways into protected areas.
- One of the priority areas is along the BR-319 highway, where experts warn deforestation may increase fourfold under another government plan to pave the highway.
- Despite the advances in comparison with former President Jair Bolsonaro, Indigenous and land reform movements are unhappy with the pace of land designation under President Luiz Inácio Lula da Silva.

Migration opens up new territories in the Brazilian Amazon in the 20th century (Nov 28 2024)
- Internal migration in Panamazonia was driven by the gold rush, improved infrastructure, land grabbing and job opportunities in large-scale infrastructure projects such as industrial mines and hydroelectric plants.
- Rondônia’s population grew from 100,000 in 1972 to more than 400,000 in 1982, when it became one of Brazil’s states. By 1990, it had surpassed one million inhabitants.
- Migration within the Brazilian Amazon is now largely internal, as Amazonian residents move to cities. Internal migration is motivated by lack of opportunity in rural communities and the creation of temporary jobs linked to construction sites

Researchers find high levels of mercury in Amazon’s Madeira River water & fish (Nov 27 2024)
- In a groundbreaking expedition, researchers from Harvard and Amazonas State University began monitoring water quality and mercury contamination in the Amazon Basin’s largest tributary.
- The Madeira River Basin has been heavily impacted by human actions, such as hydropower plants, deforestation and illegal gold mining, which degrade its ecosystems.
- Initial results from Harvard reveal high levels of mercury in the Madeira, although still below the limit recommended by Brazil’s authorities.
- Predatory fish species showed mercury levels above the recommended limit, while scalefish traditionally consumed by riverine populations were below.

Reserve in Brazilian Amazon struggles as ‘aggressive’ deforestation spreads (Nov 27 2024)
- Triunfo Do Xingu Environmental Protected Area was created to protect rich Amazonian forest and shield adjacent reserves.
- But deforestation has been rampant within the reserve and is spreading to nearby areas
- From 2006 to 2023, the reserve lost 41% of its primary forest cover.
- Preliminary satellite data for 2024 from show deforestation picking up even further, and spreading into nearby areas including Terra do Meio Ecological Station and Serra do Pardo National Park

Brazil beef industry still struggling with deforestation from indirect suppliers, survey finds (Nov 26 2024)
- Surveys of Brazil’s beef industry found there is still a serious lack of transparency throughout the supply chain, including from slaughterhouses and retailers. If better regulations aren’t implemented, they could be exposed to 109 million hectares (270 million acres) of deforestation by 2025.
- The survey was conducted by Radar Verde, a cattle monitoring initiative made up of several climate groups. It reviewed the regulations and exposure to deforestation of dozens of companies in Brazil.
- Indirect suppliers of beef are the most difficult to track, the survey found, with none of the 132 companies or 67 retailers competently able to demonstrate whether cattle had been raised on illegally deforested land.
- Struggles to monitor indirect suppliers could pose a challenge for companies trying to meet the EU deforestation-free products regulation (EUDR), which will require suppliers to prove beef and other commodities exported to the EU aren’t sourced to illegally deforested land.
