Barragem de Belo Monte no rio Xingu: 10 anos de impactos na Amazônia e de busca por reparações

A usina hidrelétrica de Belo Monte causou um desastre ambiental e social no coração da Amazônia: um dos ecossistemas mais importantes do planeta.

Essa situação só piorou desde que a usina começou a operar em 2016. A busca por justiça e reparação para as comunidades indígenas e ribeirinhas afetadas continua até hoje.

Em 2011, a Comissão Interamericana de Direitos Humanos (CIDH) concedeu a essas comunidades medidas de proteção, que até hoje não foram totalmente implementadas pelo Estado brasileiro.

E, desde junho daquele mesmo ano, a CIDH mantém um processo contra o Estado por sua responsabilidade internacional no caso.

A CIDH pode encaminhar o caso à Corte Interamericana de Direitos Humanos, que tem o poder de emitir uma sentença condenatória contra o Estado brasileiro.

Contexto

A usina hidrelétrica de Belo Monte — a quarta maior do mundo em capacidade instalada (11.233 MW) — foi construída no rio Xingu, no estado do Pará, norte do Brasil.

Foi inaugurada em 5 de maio de 2016, com uma única turbina. Naquela época, 80% do curso do rio foi desviado e 516 km² de terra foram inundados, uma área maior que a cidade de Chicago. Desse total, 400 km² eram de mata nativa. A usina começou a operar em plena capacidade em novembro de 2019.

Belo Monte foi construída e é operada pelo consórcio Norte Energia S.A., composto principalmente por empresas estatais. Foi financiada pelo Banco Nacional de Desenvolvimento Econômico e Social (BNDES), que aportou ao consórcio 25,4 bilhões de reais (aproximadamente US$ 10,16 bilhões), o maior investimento de sua história. Portanto, o BNDES também é legalmente responsável pelos impactos socioambientais associados ao projeto hidrelétrico.

Décadas de danos ambientais e humanos

As violações dos direitos humanos e a degradação da Amazônia remontam ao início do projeto. Em março de 2011, a Norte Energia iniciou a construção da barragem sem consulta adequada e sem o consentimento prévio, livre e informado das comunidades afetadas.

A construção levou ao deslocamento forçado de mais de 40.000 pessoas, rompendo laços sociais e culturais. O plano de reassentamento em Altamira — cidade diretamente afetada pelo projeto hidrelétrico — incluía moradias na periferia da cidade, sem serviços públicos adequados, moradias dignas para as famílias reassentadas e moradias diferenciadas para aqueles pertencentes a comunidades indígenas.

A operação da barragem de Belo Monte impôs uma seca permanente e artificial na Volta Grande do rio Xingu, agravada pelas secas históricas na Amazônia em 2023 e 2024. Como resultado, a morte de milhões de ovos de peixe foi documentada por quatro anos consecutivos (de 2021 a 2024) e, nos últimos três anos, não houve migração de peixes rio acima para desovar e se reproduzir. Assim, a pesca artesanal, principal fonte de proteína para os povos indígenas e comunidades ribeirinhas, foi severamente afetada: o consumo de peixe caiu de 50% para 30% do total de proteínas consumidas, sendo substituído por alimentos processados. Em suma, houve um colapso ambiental e humanitário que resultou no colapso da pesca como modo de vida tradicional, insegurança alimentar e falta de acesso à água potável para milhares de famílias, empobrecimento e doenças.

Além disso, a construção da barragem aumentou o desmatamento e intensificou a extração ilegal de madeira e a insegurança em terras indígenas e tribais, colocando em risco a sobrevivência dessas comunidades. Outra consequência foi o agravamento da pobreza e dos conflitos sociais, bem como a sobrecarga dos sistemas de saúde, educação e segurança pública em Altamira, cidade considerada a mais violenta do país em 2017, onde houve aumento do tráfico de pessoas e da violência sexual. Também foram registrados casos de violência contra defensores de direitos humanos envolvidos no caso.

Em 2025, durante a 30ª Conferência das Nações Unidas sobre Mudanças Climáticas (COP30), realizada no Brasil, o Ministério Público Federal classificou os danos causados ​​por Belo Monte como ecocídio.

A busca por justiça e reparação

Ao longo dos anos, o Ministério Público Federal do Pará, a Defensoria Pública e organizações da sociedade civil impetraram dezenas de ações judiciais em tribunais brasileiros para contestar as diversas irregularidades do projeto, bem como seus impactos. A maioria das ações permanece sem solução, algumas há mais de 10 anos.

Essas ações não obtiveram sucesso porque o governo federal tem reiteradamente anulado decisões favoráveis ​​às comunidades afetadas, recorrendo a um mecanismo pelo qual o presidente do Supremo Tribunal Federal pode suspender uma decisão judicial com base unicamente em argumentos genéricos como "interesse nacional" ou "ordem econômica".

Diante da falta de respostas eficazes em nível nacional, a AIDA — juntamente com uma coalizão de organizações aliadas — levou o caso à Comissão Interamericana de Direitos Humanos (CIDH) e, em 2010, solicitou medidas cautelares para proteger a vida, a integridade e a saúde das comunidades indígenas afetadas.

Em 1º de abril de 2011, a CIDH concedeu essas medidas e solicitou ao Estado brasileiro a suspensão das licenças ambientais e de quaisquer obras de construção até que as condições relativas à consulta prévia e à proteção da saúde e integridade das comunidades fossem atendidas.

E, em 16 de junho de 2011, apresentamos uma denúncia formal à CIDH — juntamente com o Movimento Xingu Vivo Para Siempre, a Coordenação das Organizações Indígenas da Amazônia Brasileira, a Diocese de Altamira, o Conselho Missionário Indígena, a Sociedade Pará de Defesa dos Direitos Humanos e a Global Justice — contra o Estado brasileiro por sua responsabilidade internacional nas violações de direitos humanos contra os povos afetados neste caso. A denúncia foi apresentada em dezembro de 2015.

Em 3 de agosto de 2011, a CIDH modificou as medidas cautelares para solicitar — em vez da suspensão de licenças e obras — a proteção dos povos que vivem em isolamento voluntário, a saúde das comunidades indígenas e a regularização e proteção das terras ancestrais.

Situação atual

As medidas de proteção concedidas pela CIDH permanecem em vigor, mas o Estado brasileiro não as cumpriu integralmente, relatando apenas ações genéricas. As comunidades documentaram as contínuas violações de seus direitos. A situação que motivou o pedido dessas medidas — o risco à vida, à segurança e aos meios de subsistência das comunidades — persiste e se agravou com a usina hidrelétrica operando em plena capacidade e com as recentes secas extremas na Amazônia.

Além do ocorrido em Belo Monte, existe o risco de maiores danos sociais e ambientais decorrentes da implementação de outro megaprojeto de mineração na Volta Grande do Xingu. Lá, a empresa canadense Belo Sun pretende construir a maior mina de ouro a céu aberto do Brasil.

Os impactos sinérgicos e cumulativos da usina e da mina não foram avaliados. O Estado excluiu povos indígenas, comunidades ribeirinhas e comunidades camponesas do processo de licenciamento ambiental do projeto. Apesar disso, dos protestos indígenas e de outras irregularidades em torno do projeto, o governo do estado do Pará autorizou formalmente a mina em abril de 2026.

Belo Monte, assim como outras usinas hidrelétricas, agrava a emergência climática ao gerar emissões de gases de efeito estufa em seu reservatório. Além disso, é ineficiente diante das secas prolongadas e intensas causadas pela crise, pois perde capacidade de geração de energia.

O caso perante a Comissão Interamericana

Em outubro de 2017, a CIDH anunciou que decidiria conjuntamente sobre a admissibilidade (se o caso preenche os requisitos para admissão) e o mérito (se houve, de fato, violação de direitos humanos) da denúncia internacional contra o Estado brasileiro.

Quinze anos após a apresentação da denúncia, as comunidades afetadas e as organizações que as representam ainda aguardam essa decisão. Caso a CIDH conclua que houve violações de direitos humanos e emita recomendações que o Estado brasileiro não cumpra, poderá encaminhar o caso à Corte Interamericana de Direitos Humanos, cujas decisões são vinculativas.

Uma possível decisão da Corte Internacional de Direitos Humanos neste caso estabeleceria um precedente jurídico regional em relação aos direitos dos povos indígenas e ribeirinhos, à participação pública em megaprojetos e à responsabilidade do Estado no contexto da crise climática. Isso é particularmente relevante à luz do Parecer Consultivo nº 32 da Corte, que reafirmou as obrigações dos Estados de proteger pessoas e comunidades em todo o continente da emergência climática.

Open Letter from Civil Society Organizations to the President of the Inter-American Development Bank

The undersigned group of civil society organizations greet you as you begin your term as President of the Inter-American Development Bank. We extend to you our best wishes as you assume this task of great responsibility for the people of Latin America and the Caribbean.We take this opportunity to introduce ourselves and express our willingness to continue contributing to the Bank's actions pursuing the region's development. Since 2017, our organizations have been monitoring and making recommendations on the IDB policies and projects, in partnership with local communities and populations. In particular, we promote the Bank’s establishment of better social and environmental policies and practices, as well as adequate and transparent spaces for participation that allow improving the IDB's link and interaction with civil society. To mention just a few examples, we highlight our contributions to the Environmental and Social Policy Framework (ESPF), to the updates of the MICI policy and in the accompaniment of specific cases, and in the revision process of the Access to Information Policy and in the dialogues on the IDB-Amazon Initiative.In conjunction, we are permanently monitoring the Bank's policies and investments throughout the region, including in projects involved in the response to and recovery from the Covid pandemic and many others.We consider it essential that the Bank strengthen its practices and operations, facilitating the promotion and respect for human rights, with special attention paid to the needs of communities and indigenous peoples who are at the forefront in the defense of nature, as well as the protection of key ecosystems in the fight against climate change.Given the relevance of public participation in promoting full development, we reiterate our request to the Bank to generate constructive and lasting participation mechanisms. In particular, we request that the space for dialogue with civil society be reopened in the framework of the next IDB Annual Meetings. This space was a traditional practice that was interrupted in 2014 and has not been resumed to date.We understand that a space for IDB articulation with civil society (social organizations and movements, Indigenous groups, and others who are affected) is not only a good practice that other multilateral agencies are already implementing, but would also contribute to advance the objectives of your administration. As stated in your inaugural speech last January, you stressed your desire to "seize all opportunities for dialogue" and collaborate with different actors to address the most pressing problems of our region.Thus, your administration has an historic opportunity to generate greater openness towards civil society organizations and communities potentially affected by Bank-financed operations. We believe that this demand can no longer be postponed, and that this long-standing claim must be addressed in order to strengthen the work together with the peoples of the region.We remain at your disposal to discuss the points raised in this letter and other matters of common interest at your convenience. Kind regards, Accountability CounselAMATE El SalvadorArticulación Salvadoreña de Sociedad Salvadoreña de Sociedad Civil para la Incidencia en las Instituciones Financieras Internacionales (ASIFI)Asociación Ambiente y Sociedad (Environment and Society Association)Interamerican Association for the Defense of the Environment (AIDA)International Accountability ProjectBank Information CenterCenter for International Environmental Law (CIEL)Coalition for Human Rights In DevelopmentCohesión Comunitaria e Innovación Social A.C.

Oceans

Decision time for world’s governments on new global treaty for the ocean

New York: Today governments resume negotiations at the United Nations in New York to finalize a new High Seas Treaty to ensure the conservation and sustainable use of marine biodiversity of areas beyond national jurisdiction. The two-week Intergovernmental conference is taking place from 20 February to 3 March 2023 and is a resumption of negotiations from August 2022, when governments ran out of time. Covering half of the planet, the High Seas support vibrant marine ecosystems, life that is vital to the global food supply, and the planet’s climate system. However, it has been plagued by poor or patchy governance, and with only 1.2% protected, vast High Seas areas are open to unsustainable exploitation. This new treaty aims to address these shortcomings and offers a historic opportunity to put in place game-changing new measures for the ocean, including establishing highly and fully protected areas and strengthening assessment and management of human activities. The recent global commitment to protect at least 30% of the ocean by 2030 (the “30x30” goal) offers an ambitious backdrop for ensuring this new treaty provides the legal tools to turn the target into a reality. The pressure is now on governments to ensure the treaty that is finally agreed upon will be ambitious enough to result in a healthy ocean rather than a degraded one. Key issues that still need to be addressed at the meeting include: measures to ensure that the new treaty can deliver effective new marine protected areas rather than “paper parks”; safeguards to avoid harm arising from human activities affecting the high seas and the deep seabed; a strong institutional framework to ensure effective implementation and compliance; decision-making rules to avoid enabling one or two countries to block progress; and critical finance and equity issues related to capacity building and the sharing of benefits from marine genetic resources. "We came frustratingly close to getting this treaty over the line in August at what was supposed to be the final round of negotiations. With the accelerating climate and biodiversity crises, time is not a luxury we have to put ocean health back on track," said Sarah Bevis from the High Seas Alliance. "This time round we need to seize the moment and get an ambitious treaty over the finish line, so we can roll up our sleeves and work on the crucial tasks of getting the treaty ratified and implemented."   Additional Quotes from High Seas Alliance member organizations: Dr Laura Meller, Oceans Campaigner and Polar Advisor, Greenpeace Nordic said: "The oceans support all life on Earth. Their fate will be decided at these negotiations. The science is clear. Protecting 30% of the oceans by 2030 is the absolute minimum necessary to avert catastrophe. It was encouraging to see all governments adopt the 30x30 target last year, but lofty targets mean nothing without action." "This special session taking place so soon after the last round of negotiations collapsed gives us hope. If a strong Treaty is agreed on the 3rd of March, it keeps 30x30 alive. Governments must return to negotiations ready to find compromises and deliver an effective Treaty. We’re already in extra time. These talks are one final chance to deliver. Governments must not fail."   Trevor Jones, Campaign Manager, Only One said: "Without protections for the high seas, we cannot hope to have a healthy ocean, and without a healthy ocean we put marine life, coastal livelihoods, and global food stability at grave risk. Millions of people from around the world have spoken out: They want a strong High Seas Treaty, and they’re counting on their leaders to finally get the job done."   Liz Karan, Director of Pew’s Ocean Governance Project said: "The high seas support diverse marine life and unique ecosystems critical to the health of our ocean and planet. Countries must seize this opportunity to finalize a robust high seas treaty to establish highly protected, cross sectoral high seas MPAs for the benefit of current and future generations."   Jennifer Morris, CEO of The Nature Conservancy said: "Ensuring legal protection for the vast areas of open ocean beyond national jurisdiction, and actively acknowledging the importance of addressing this situation, is a pivotal step in moving toward our ambitious ‘30x30’ target in the new UN Global Biodiversity Framework. Ensuring a successful outcome from the New York negotiations, in the form of a formally agreed and legally binding High Seas Treaty, is imperative to meet the collective commitment to conserve 30% of the Earth’s ocean this side of 2030."   Gladys Martínez, Executive Director of the Interamerican Association for Environmental Defense (AIDA) said: "The high seas urgently needs a governance framework. We look forward to states concluding a strong and ambitious treaty during these two weeks."   Fabienne McLellan, Managing Director OceanCare said: "We have high hopes that governments will find a way to finalize the High Seas Treaty during the resumed session of IGC 5. Countries must understand that it would be grossly negligent to once again fail to conclude an agreement to conserve marine diversity in areas beyond national jurisdiction. The climate and biodiversity crises are in full swing, and the ocean is our ally, not an infinite resource to be exploited. It is not only important that the Agreement is finalized, but what is agreed needs to make a tangible difference in protecting biodiversity. Against this backdrop, it is difficult to imagine that no agreement will be reached - the agreement is vital for marine biodiversity, a healthy ocean and thus also for us humans".

Climate Change, Human Rights

Actions and reasons to preserve the Amazon

Shared by eight countries and home to 10 percent of the planet's known biodiversity, the Amazon is the largest tropical forest in the world. It’s also a global climate stabilizer, storing between 90 and 140 billion metric tons of carbon dioxide (CO2)—one of the most harmful greenhouse gases that, when released, accelerates the climate crisis. For more than 470 communities of indigenous and traditional peoples, the Amazon is an ancestral place of life, from which they have developed their ways of being in the world. However, the rainforest is facing various threats—including colonization, deforestation and extractive activities—that increase its vulnerability and affect the human rights of those who inhabit and protect it. These pressures have caused some areas of the Amazon to emit more carbon dioxide than they absorb. This situation poses the challenge of implementing strategies for the legal protection of Amazonian territories that articulate with the struggles of affected peoples. At AIDA, we have strengthened these strategies and have supported community processes aimed at combating the damage caused by mining and oil exploitation in Amazonian territories in three countries. With hopes currently pinned on the incoming government of Lula da Silva in Brazil—who announced his goal of reducing deforestation in the Amazon to zero by 2030—the preservation of this ecosystem requires political will and strong coordinated and cross-border actions. In this regard, Colombia proposed a common front to defend the Amazon rainforest. Strengthening legal defense AIDA's work strengthened the capacities of national organizations in Brazil, Ecuador and Peru for legal defense of the Amazon. Brazil: By highlighting the shortcomings of its environmental impact study, we helped ensure that the communities affected by the Volta Grande mining project of the Canadian company Belo Sun are included in the environmental authorization process and that the state is obligated to consult with them to obtain their consent. We also prepared a report for UN agencies in which we identified measures to guarantee the safety of environmental defenders in the Amazon region. Ecuador: We strengthened litigation strategies to halt the implementation of a decree by which the government seeks to expand mining exploitation in the country, with serious impacts for the Amazon region. We also generated greater understanding of the tools needed to develop strategic litigation and improve the communication skills of indigenous peoples. Perú: We supported the acceleration of litigation aimed at ensuring the repair and maintenance of the Norperuano oil pipeline, whose operation has generated serious environmental impacts and human rights violations for indigenous peoples affected by oil spills. In all three countries, we were able to advance towards a more precise understanding of the legal protection needs of the Amazon and the contexts in which such strategies should be developed. This was made possible by working in partnership with national and local organizations and indigenous peoples. Arguments to protect the ecosystem There are many reasons to preserve the Amazon, whose importance is regional and global. In order to strengthen communication efforts linked to the legal protection of the ecosystem, AIDA has developed two infographics that present in a schematic and didactic way the arguments for defending the Amazon territories, as well as their inhabitants, in court. The focus of one of the infographics is the vast biodiversity contained in the Amazon. Some figures show its high levels of richness: 40,000 species of plants; 16,000 of trees; 3,000 of fish; 1,300 of birds; more than 430 of mammals; more than 1,000 of amphibians; and more than 400 species of reptiles; therefore, any intervention in the Amazon rainforest must start from the knowledge of it as a highly diverse, complex and interconnected territory. The richness of the Amazon is also cultural, represented in the indigenous and traditional peoples that have inhabited the ecosystem since ancestral times, whose diversity is present in 86 languages and 650 dialects. The Amazon: A megadiverse region (in Spanish)   The other infographic illustrates the capacity of the Amazon to regulate the humidity and climate of the continent. In addition to storing large amounts of carbon dioxide, the ecosystem absorbs half of the solar energy it receives through the evaporation of water from its foliage. Most of the trapped energy is released when the vapor condenses to form clouds and rain. Among other things, the Amazon recycles between 50% and 70% of annual precipitation, pumping some seven billion tons of water a year into the atmosphere through evapotranspiration. The Amazon: A global climate regulator (in Spanish)   The Amazon and its care are emblematic of the intrinsic relationship and balance that must exist between a healthy environment and human existence. "The spirits that give us life exist in the forest, the water and the air. We all have a correlation," said Humberto, a member of a community in the Ecuadorian Amazon. "That existence is what we call life—our own home, the pharmacy, nature or what we can call, in general, the existence of man and nature."
