Brazil's Double Game: Host of Wildlife Protection and Driver of Habitat Destruction

Brazil is hosting the 15th Conference of the Parties to the Convention on the Conservation of Migratory Species from March 23 to 29, 2026, in Campo Grande, Mato Grosso do Sul. At the same time, satellite data from Brazil's own space research institute shows continued destruction of the habitats those species depend on. This is what the available evidence shows.

Situation Assessment

Brazil has been a party to the Convention on the Conservation of Migratory Species (CMS) since October 2015. The country harbors an estimated 20 percent of the world's biodiversity and provides critical habitat for hundreds of migratory species, including Neotropical migratory birds, river dolphins, sea turtles, and marine fish.

CMS COP15 takes place at the Bosque Expo venue in Campo Grande, at the gates of the Pantanal, one of the biomes whose species the conference aims to protect. Brazil's hosting role places the country's environmental record under direct scrutiny from more than 130 other CMS parties and dozens of observer organizations.

The Brazilian delegation arrived with a dual narrative: progress on Amazon deforestation reduction under President Lula's administration, and new commitments to protect migratory species corridors. The question is whether the data supports that narrative.

What the Numbers Show

Brazil's National Institute for Space Research (INPE) operates two deforestation monitoring systems. PRODES measures annual clear-cut deforestation. DETER provides near-real-time alerts. Both paint a mixed picture.

Amazon deforestation fell significantly in 2023 and 2024 compared to the peak years of 2020-2022 under the Bolsonaro administration. INPE's PRODES data recorded approximately 9,001 square kilometers of deforestation in the Legal Amazon for the August 2022 to July 2023 period, down from roughly 11,568 square kilometers the previous year. The downward trend continued: the August 2024 to July 2025 PRODES figure fell to 5,796 square kilometers, representing a cumulative reduction of approximately 50 percent from the 2022 peak.

This assessment requires context. The Amazon is not the only biome under pressure. The cerrado, Brazil's tropical savanna and the world's most biodiverse savanna ecosystem, lost approximately 11,022 square kilometers of native vegetation in the 2022-2023 period according to INPE's PRODES data, with 75 percent of this deforestation concentrated in the MATOPIBA region. The cerrado's deforestation rate exceeded the Amazon's in that period, but receives a fraction of the attention. By the 2024-2025 period, cerrado deforestation declined to 7,235 square kilometers, an 11.5 percent reduction.

The Pantanal, the world's largest tropical wetland, experienced severe fires in 2024. INPE fire monitoring data recorded more than 1.3 million hectares burned through August 2024, with June alone seeing approximately 440,000 hectares destroyed, exceeding any previous June on record. This was one of the worst fire seasons ever documented for the biome.

MapBiomas, a collaborative platform that tracks land use across Brazilian biomes, documented continued agricultural expansion into all three biomes throughout 2024 and into 2025. Notably, while deforestation declined, forest degradation in the Amazon increased by 44 percent compared to 2023, affecting over 2.5 million hectares.

Migratory Species in the Crosshairs

The cerrado serves as a critical wintering and stopover habitat for dozens of Nearctic-Neotropical migratory bird species that breed in North America and migrate south. Species including the upland sandpiper and the bobolink depend on intact cerrado grasslands during the Southern Hemisphere summer.

The Pantanal functions as one of the most important wetland stopover sites for migratory waterbirds in the Americas. The jabiru stork, wood stork, and numerous heron species use the Pantanal's seasonal flood pulse for breeding and feeding. When fire destroys wetland vegetation, these species lose nesting habitat.

In the Amazon basin, the boto (Amazon river dolphin, Inia geoffrensis) undertakes seasonal movements tied to flood cycles. The species is classified as endangered on the IUCN Red List. In late 2023, a severe drought killed more than 200 dolphins, including botos and tucuxis, in and around Lago Tefé in Amazonas state, as water temperatures exceeded 39 degrees Celsius with peaks reaching 41 degrees. Dam construction and water level changes from deforestation-driven hydrological shifts compound these threats.

Brazil's Atlantic coast provides nesting habitat for five species of sea turtle, all of which are migratory and CMS-listed. Coastal development and light pollution disrupt nesting behavior and hatchling orientation.

The maned wolf, though not a long-distance migrant, requires large territorial ranges across the cerrado. Habitat fragmentation from soy expansion has isolated populations, reducing genetic exchange between groups.

Infrastructure vs. Migration Corridors

Several major infrastructure projects threaten to sever or degrade migratory corridors in Brazilian biomes.

The BR-319 highway, connecting Manaus to Porto Velho across approximately 870 kilometers of largely intact Amazon rainforest, is undergoing reconstruction. Research from the Federal University of Minas Gerais indicates that paving this road would cause a fourfold increase in deforestation rates in the surrounding area. Satellite monitoring has already documented 132,000 hectares of tree loss around the road. DNIT obtained a preliminary environmental license in July 2022 during the Bolsonaro administration, but IBAMA's technical staff have repeatedly questioned the adequacy of the environmental impact study, and the license was subsequently challenged in court.

The Ferrogrão railway project proposes a 933-kilometer grain transport corridor from Sinop in Mato Grosso to the port of Miritituba in Pará, running parallel to the BR-163 highway through the Amazon-cerrado transition zone. The project would cut through the Jamanxim National Forest and affect Indigenous territories. The Supreme Federal Tribunal has been deliberating on the project's constitutionality, with proceedings suspended since October 2025. Legislative efforts to advance the project continued through 2025, driven by the agribusiness lobby, with an auction scheduled for September 2026.

Hydroelectric dams on Amazon tributaries block fish migration routes. The Belo Monte dam on the Xingu River, completed in November 2019 with an installed capacity of 11,233 MW, altered flow patterns in the Volta Grande do Xingu critical for migratory fish species including the jaraqui and tambaqui, which undertake seasonal migrations of hundreds of kilometers along Amazonian rivers.

Marina Silva's Constrained Position

Marina Silva returned as Environment Minister in January 2023 with a mandate to reverse the environmental rollbacks of the Bolsonaro era. Her track record shows both accomplishments and constraints.

On the enforcement side, IBAMA conducted significantly more operations in 2023-2024 than during the Bolsonaro years, when enforcement was systematically weakened. Fines for illegal deforestation increased. The agency's staffing, however, remained critically low. As of 2024, IBAMA had approximately 700 active field inspectors responsible for monitoring a national territory of 8.5 million square kilometers. In 2009, the agency had roughly 1,800 agents; by 2021, that number had fallen to 630. Recruitment efforts have since brought the figure to approximately 771 by mid-2025, still far below operational requirements.

Silva's ministry faces structural opposition within Lula's own coalition. The agricultural caucus (bancada ruralista) holds significant congressional power and has advanced legislation to weaken environmental protections. In 2023, Congress passed bills reducing the protection status of certain conservation areas and limiting the demarcation of Indigenous territories, both of which serve as de facto wildlife corridors.

The environment ministry's budget, while increased from Bolsonaro-era lows, remained modest relative to the scale of enforcement required. The Amazon Fund, replenished with international donations after being frozen under Bolsonaro, provided additional resources but could not substitute for structural government investment.

This suggests that Silva's position is one of damage limitation within a government whose economic priorities frequently override environmental ones. Her hosting of CMS COP15 gave international visibility to Brazil's conservation challenges, but the policy tools at her disposal remain limited.

What Brazil Proposed and What It Blocked

At CMS COP15, Brazil supported the listing of several shark and ray species on CMS Appendix II, consistent with its broader support for marine species protections. The country also co-sponsored resolutions on reducing bycatch and addressing light pollution impacts on sea turtles.

Brazil promoted language emphasizing the importance of ecological connectivity and the integration of migratory species considerations into infrastructure planning. This is notable given the country's own infrastructure pipeline.

Unclear remains what Brazil's position was on binding enforcement mechanisms. CMS historically relies on voluntary compliance rather than sanctions. Several observer organizations reported that Brazil, along with other developing nations, resisted proposals to create binding reporting requirements for habitat protection, arguing for the principle of "common but differentiated responsibilities."

Brazil pledged financial contributions to the CMS Small Grants Programme and announced a national action plan for migratory species in the Amazon basin. The details of this plan, including timelines, funding sources, and measurable targets, have not been published at the time of writing.

What We Don't Know

Several transparency gaps limit a full assessment of Brazil's environmental credibility.

INPE's monitoring systems cover the Amazon comprehensively but provide less complete coverage of the cerrado and Pantanal. MapBiomas has improved cerrado monitoring, but degradation short of clear-cutting is difficult to detect from satellite data. This means that habitat quality loss, as opposed to outright deforestation, is likely underreported.

The environmental impact assessments for major infrastructure projects, including BR-319, are not fully available to the public. Environmental groups have challenged the adequacy of the assessments that have been released.

Data on migratory species populations within Brazilian biomes is limited. Brazil lacks a systematic national monitoring program for most migratory bird species. The Chico Mendes Institute for Biodiversity Conservation (ICMBio) maintains species assessments, but many are outdated or based on incomplete survey data.

The extent of illegal deforestation not captured by monitoring systems is, by definition, uncertain. Estimates vary, but forest degradation through selective logging and fire that does not result in complete canopy loss is known to be substantially underreported. The 44 percent increase in Amazon degradation documented in 2024-2025 underscores this gap.

Assessment

The available evidence suggests a structured contradiction in Brazil's position.

The Lula government has demonstrably reduced Amazon deforestation compared to its predecessor, achieving a roughly 50 percent reduction from 2022 levels by 2025. This is a measurable achievement confirmed by independent satellite data. It does not, however, constitute a reversal. Deforestation continues, the cerrado and Pantanal face intensifying pressure from agricultural expansion and fire, and forest degradation is increasing even as clear-cutting declines.

Brazil's hosting of CMS COP15 placed the country in a position where its diplomatic commitments exceeded its demonstrated capacity for domestic implementation. The gap between conference rhetoric and ground-level environmental enforcement is not unique to Brazil. Host countries of environmental summits routinely face this credibility test.

The critical indicator going forward is whether the national action plan for migratory species announced at COP15 materializes as a funded, enforceable policy, or remains a diplomatic statement. The infrastructure decisions on BR-319 and Ferrogrão will serve as concrete tests of whether ecological connectivity considerations enter Brazilian planning practice.

The data does not support a conclusion that Brazil is acting in bad faith. It does support a conclusion that the structural pressures on Brazilian migratory species habitats exceed the policy instruments currently deployed to protect them.
