Six Biomes, Multiple Realities, One Country: What Was Learned at the 2026 Lemann Dialogue

Panel 2 - Climate Change in the Semi-Arid

Caatinga: Adaptation and Sustainability

Speakers: Marcelo Leite, Kenia Rios, Washington Franca-Rocha, Daniela Nogueira

The Caatinga is the only exclusively Brazilian biome and one of the most vulnerable to climate change. The panel highlighted that the stigma of a 'dry and dead biome' has hindered investment and preservation.

Key Insights:

• Monitoring Blind Spots: Large-scale deforestation often goes unrecorded by traditional satellite methods because the biome’s deciduous nature mimics degradation. Better sensors and specialized monitoring are critical.
• The Desertification Crisis: With 60% of the territory at risk, the focus must shift from "fighting drought" to "coexisting with the semi-arid," valuing traditional agro-ecological practices.
• Renewable Energy Paradox: While the Pampa and Caatinga are hotspots for wind and solar energy, poorly planned infrastructure is becoming a new driver of habitat fragmentation.

Key Indicators

• Only exclusively Brazilian biome
• 46% of territory already deforested
• 60% at risk of desertification

"The Caatinga can shift from being a dryland hotspot to a hotspot for adaptation and living in harmony with the environment in a dignified manner, bringing together people and communities in all their diversity." — Daniela Nogueira

Panel 3 - The Advocacy Frontier

Amazon: Bioeconomy and Climate Justice

Speakers: Marcia Castro, Vanda Witoto, Philip Fearnside, Ane Alencar

The Amazon debate shifted from biology to geopolitics. The panel underscored that the biome's stability is now a matter of national security and international credibility.

Expert Consensus:

• Law Enforcement as Baseline: Technology alone (DETER/PRODES) is not stopping deforestation; organized crime has adapted. The State must regain territorial control through intelligence and field presence.
• Beyond Extraction: A viable bioeconomy requires moving from low-value raw extraction to complex nature-based products, utilizing indigenous technologies as part of the industrial matrix.
• Climate Justice: The protection of the forest is inseparable from the protection of its people. Investing in urban infrastructure in Amazonian cities is essential to reduce the social pressure on the forest frontier.

Key Indicators

• Recent Trend: 65% Deforestation drop
• Economic Goal: High-complexity Bioeconomy

"The earth is our mother, the forest is our sister, and the rivers are our grandparents. They are family members we need to care for and who need to exist, just as we do." — Vanda Witoto

Panel 4 - Agriculture and Preservation

Cerrado: The Cradle of Waters at Risk

Speakers: Sandro Dutra e Silva, Ryan Nehring, Ludmila Rattis, Mercedes Bustamante

The Cerrado is Brazil's "upside-down forest," where the majority of carbon and water storage happens underground. Its rapid conversion is threatening the very hydrologic cycles that sustain Brazilian agribusiness.

Critical Findings:

• The Hydrologic Disconnect: The destruction of the Cerrado plateau directly impacts the energy security of the South/Southeast and the irrigation capacity of the Central-West.
• Carbon Market Misalignment: Current carbon markets often fail to value the massive root systems of the Cerrado, leading to skewed incentives that favor reforestation with exotic species over protecting native grasslands.
• Pasture Intensification: Brazil has enough degraded pasture to triple its agricultural output without clearing a single new hectare of Cerrado.

Key Indicators

• Hydrology: Cradle of 8 of 12 basins
• Carbon: Massive underground storage
• Threat: Fastest conversion rate in Brazil

"Agribusiness in Brazil is destroying the very water source that allows it to exist." — Mercedes Bustamente

Panel 5 - Biodiversity and Territory

Pantanal: Fire Challenges and Private Property

Speakers: Renato Roscoe, Gilson Barros, Teresa Bracher

The Pantanal highlights a unique challenge: the majority of the biome is privately owned. Conservation strategy is a matter of engaging with the traditional ranching community to adapt to a changing climate.

Panel Highlights:

• Fire Management: The fires of 2020/2024 proved that total fire exclusion policies fail. Integrated Fire Management (MIF) using controlled burns and professional brigades is the new standard.
• Traditional Cattle Ranching: Extensive, low-impact ranching is the historical guardian of the biome. Its economic viability must be protected to prevent land conversion to intensive soy or sugarcane.
• Highlands Interdependence: The Pantanal is a "drainage basin"—its health is 100% dependent on the preservation of the Cerrado springs in the surrounding highlands.

Key Indicators

• 97% private territory
• Total dependence on Cerrado water
• Critical risk of savannization

"97% of the territory is composed of private properties... conservation in the Pantanal needs to sit at the table with the rural producer." — Renato Roscoe

Special Session - Documentary: Pampa, the Invisible Biome

Pampa: The Invisible Heritage

Speakers: Marcelo Elvira

The Pampa is marginalized both in the environmental agenda and the national imagination. It is seen as "empty space" or "the end of Brazil," but it is an ecosystem with unique biodiversity under threat.

• Invisibility: Documentary storytelling is being used as a new strategy to reach audiences technical documents cannot.
• Legislative Vigilance: Permanent monitoring in Congress is required to prevent setbacks in the Forest Code.
• National Asset: The biome needs to be elevated to national status in policy, not relegated to regional concern.

Key Indicators

• Lowest level of legal protection
• Accelerated Native Loss

"The Pampa is a Brazilian biome... it must be thought of as a national heritage, not just a Rio Grande do Sul issue." — Marcelo Elvira
