Acre’s road push risks reversing forest gains and carbon income

Local leaders want new road links to Peru to boost trade, but environmental groups warn the extension would drive deforestation, threaten Indigenous territories and put Acre’s carbon-credit revenue at risk.

Useful takeaways from this story.

See All Key Ideas Along a freshly repaved stretch of the BR-317 highway in Acre, a Brazilian state bordering Bolivia and Peru in the Western Amazon, pasture stretches out as far as the eye can see.

Solitary Brazil nut trees (Bertholletia excelsa), a protected species, are the only reminder of the tropical forest that once stood there.

The road is part of the Interoceanic Highway, inaugurated in 2011 as the first paved road in South America connecting the Atlantic and Pacific oceans.

# What's happening Along BR-317 in Acre, pasture now replaces much of the forest that once bordered the highway. That road is part of the Interoceanic Highway, opened in 2011, and has been linked to deforestation on both sides of the Brazil–Peru border.

# Why this matters

Peru, opened in 2024, has renewed political momentum for Pacific-oriented corridors across the Amazon. Acre officials see the state as strategically placed for exports, but environmentalists say the trade argument conflicts with Acre's deforestation commitments.

# Where the risks concentrate

Uncertainty about the road's future is already reshaping behavior on the ground. Between Mâncio Lima and Serra do Divisor, land speculation is increasing and criminal groups established along the border are exploiting the situation, according to local environmentalists.

# Recent deforestation trend in Acre

# Trade-offs for policymakers Policymakers face concrete trade-offs: road-building can reduce transport costs and open markets for agricultural and mineral exports, but it typically expands the footprint of deforestation and illegal land occupation. The Amazon Conservation report frames the choice as incompatible with Acre's current commitments to limit forest loss and to generate carbon-credit revenue for sustainable development.

# What stakeholders are saying Researchers and conservation groups warn roads are the primary vector for deforestation and irregular land occupation in Acre. State authorities and some local politicians continue to advocate for corridor development to the Pacific, citing regional integration and economic opportunity.

# Short-term signals to watch

  • Formal decisions on extending BR-364 or other corridor projects.
  • Land transactions and evidence of speculative clearing near Mâncio Lima and Serra do Divisor.
  • Electoral results at state and national levels that could shift infrastructure priorities.

# Bottom line Extending road access in Acre would likely open new areas to clearing and settlement, which could undo recent reductions in deforestation and reduce the value of carbon-credit strategies meant to fund sustainable alternatives. Political choices in the near term will determine whether Acre follows a development path focused on roads and export corridors, or one that preserves forest-based revenue streams and protected lands.
