Criminal gangs now operate in nearly half of all towns in the Brazilian Amazon—a dramatic escalation that intertwines environmental crime, drug trafficking, political risk, and global climate danger.
The Brazilian Amazon is experiencing a seismic shift in its social and environmental landscape. Organized criminal gangs now exert control over 344 out of the region’s 772 municipalities—nearly 45%—a leap of 32% in just one year, according to the latest findings from the Brazilian Forum on Public Safety. This criminal surge is transforming the Amazon into a battleground not just for law enforcement but for all those invested in global climate, indigenous rights, and regional security.
The Accelerated Spread of Crime Across the Rainforest
A mere year ago, organized gangs were present in 260 Amazon municipalities. Today, their reach has exploded, doubling from levels seen just two years before. The powerful Red Command and First Capital Command syndicates, alongside a constellation of at least 17 other criminal factions—including Venezuela’s Tren de Aragua—now operate a network that rivals the scope of state authority in many areas. Their criminal portfolios extend far beyond drug trafficking, incorporating environmental crimes like illegal logging and mining, extortion, and territorial disputes that are rapidly escalating violence.
- Red Command: Doubled its presence since 2023, controlling river trafficking routes in partnership with Peruvian and Colombian cartels.
- First Capital Command: Bases its operations from Sao Paulo, focusing on clandestine airstrips in mining-rich regions.
- Tren de Aragua (Venezuela): Increasingly active and targeted by international military efforts.
Why This Escalation Matters Now
The timing of this surge is critical. As Belem hosts the COP30 United Nations Climate Summit, the Amazon’s security crisis presents a direct threat to both local stability and global environmental goals. The Amazon rainforest is a linchpin of the world’s climate system, storing vast amounts of carbon and sustaining global biodiversity. The rise of criminal control threatens the forest’s survival, undermining efforts to combat climate change and protect indigenous communities.
The surge in gang activity brings a cascade of urgent consequences:
- Violence Surging Above National Averages: The Amazon saw 8,047 slayings in 2024—a homicide rate 31% above Brazil’s national average.
- Environmental Devastation: Illegal mining and deforestation are increasingly run by criminal groups leveraging their territorial control for fast profit at great ecological cost.
- Indigenous and Local Insecurity: The expansion of organized crime disrupts indigenous communities, who often stand on the frontline of both environmental protection and criminal intrusion.
- Threats to International Security: The Amazon has become a critical juncture for international drug routes and smuggling, connecting Latin America to global trafficking networks.
Political Repercussions: Brazil Responds Under Global Pressure
In response to the spiraling crisis, Brazil’s lower house has fast-tracked a bill to toughen penalties for gang membership and related violent crimes. Recommended sentences for intentional homicide could rise from 6–20 years to as much as 40 years when committed by those affiliated with organized groups. New powers are proposed for asset seizure and the transfer of gang leaders to maximum-security prisons even before final judgment.
However, this legislative momentum has run into political and financial resistance. President Luiz Inácio Lula da Silva warned that proposed budget cuts to the federal police risk neutering the country’s response, expressing concern over the bill’s efficacy in the current political climate.
Beneath these government debates, public anxiety is running high. As gangs become an unavoidable reality for millions of Brazilians, support for tough law-and-order measures is growing across the electorate.
The Historical Roots and International Dimensions
The origins of today’s gang crisis stretch back to Brazil’s prison system and urban crime networks of the 1990s. Groups like the Red Command grew out of Rio de Janeiro’s favelas and quickly formed alliances with other South American cartels, leveraging the Amazon’s porous frontiers and infrastructure gaps to expand their smuggling routes. In recent years, international groups—like the Tren de Aragua—have exploited regional instability to establish their own bases of operation.
Cross-border flow of drugs, gold, and timber has turned the Amazon into a global trafficking corridor, regularly drawing international attention and, on occasion, military responses, such as those mounted by the United States against Tren de Aragua.
What’s Next: Can Brazil and the World Turn the Tide?
With crime entangled in the Amazon’s social and ecological fabric, experts argue that enforcement alone will not suffice. The Brazilian Forum on Public Safety warns that only providing local communities with viable economic alternatives can stem the underlying motivations for illicit activity. Solutions must therefore combine tough policing with sustainable development and regional cooperation.
- Integrated Environmental and Security Policy: Without addressing the underlying drivers—poverty, lack of opportunity, and corruption—gang activity is set to further entrench itself in Amazonian society.
- Sustainable Economic Alternatives: Transitioning the Amazon from predatory extraction to long-term sustainable growth must lie at the heart of any policy response.
- International Collaboration: As trafficking routes cross borders, Brazil’s efforts will only succeed as part of a broader regional and global effort.
The accelerating criminal takeover of Amazonian towns now stands among the most urgent policy challenges for Brazil and the world. The consequences are profound: not only for the rainforest, but for the planet’s climate, regional security, and the lives of millions.
