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.

¡Gracias totales!

I’m ending an era of 18 great years at AIDA, my second home. Words are not enough to describe how grateful, proud and happy I feel as I take stock of the achievements, progress and lessons learned. I treasure the wonder of meeting and sharing this journey with so many people in every corner of our Americas and beyond; the blessing of traveling rivers, mountains and territories and learning with and from each and every person and community. For all of this, I can only say: ¡Gracias totales! This has been the work of my dreams and the great honor of my life: to be able to build and lead this organization, alongside great people, building community from our female leadership, contributing throughout the continent to the protection of territories, rights and the environment. I am deeply grateful for the company, support, mentorship, inspiration, and sisterhood of Anna Cederstav, with whom I shared the dream and leadership of AIDA during this time, and who will continue in the organization supporting the new executive leadership. It is impossible to imagine a better co-director. Infinite thanks also to the Board of Directors for their trust and continued support. It is great to know that the organization has your back to ensure its growth and transcendence in these times of change. To each of the people of my current team and of all these years, words cannot express my admiration and deep gratitude for their invaluable commitment, professionalism, love and dedication. The results achieved are thanks to you all. It is very gratifying to have contributed to important advances in the region, including making visible and supporting the fights for justice in La Oroya, Peru, and in the Xingu River basin in Brazil; helping to protect the San Pedro Mezquital and Papagayo rivers in Mexico, the páramos in Colombia, the corals and mangroves on our coasts; conserving turtle nesting areas such as Las Baulas in Costa Rica; helping improve the Constitution in Mexico; helping include human rights in climate agreements and improving standards to protect rivers and mangroves; helping improve the safeguards of some international financial institutions; and contributing to the advancement of jurisprudence in the Inter-American System, including the recognition that climate change impacts human rights. It has been even more gratifying to have achieved all this together with great people both in our team and in various organizations, networks, communities and national and international entities. Today especially, and in view of the climate crisis and the reality of our region, it is essential to continue advancing in the collective work with and from the territories, motivating the diversity of knowledge and seriously including the perspective of women, youth and communities to reach the solutions that have so far proved elusive. This has all been a learning experience, because each achievement has been the result of close coordination, and of the diverse and complementary contribution of multiple visions. I am confident that this perspective will continue to be strengthened in order to make further progress towards finding solutions for our collective challenges. The magnitude of the climate and biodiversity crisis, the imperative need for a transformative recovery, and effective protection of human rights defenders, the environment and territory are three priorities that require our best efforts and impact. It is comforting to know that we have helped strengthen and build a great regional and global community with whom we share the goal of advancing the outcomes that people, communities, nature, and our societies and countries so desperately need. It is one of my greatest rewards after so many years of work. For all these reasons, and given that the only constant in life is change, the time has come to give free rein to new leadership. This decision has been difficult because this has been my home for so long. I first heard about AIDA in July 1997, when the organization was still in its infancy and I was studying law and working at Fundepúblico in Colombia. Upon learning of their intention to work on public interest environmental law in and from Latin America, I knew immediately that it was my place. I started as an intern in May 2003 and, a few months later, the Board of Directors hired me as an attorney. My heart did not fit in my chest and the ideas did not stop running through my mind. Today I have the satisfaction of having done my best to make a positive contribution to my region, putting law and science at the service of people, communities and the environment. In the process, I was also able to grow as a lawyer, and a leader, while building my family and becoming a wife and mother. After countless adventures, learning, successes and failures, it is time to embark on other paths and embrace change. I will continue to contribute to the understanding of the climate crisis and especially to identify how we can move towards climate justice with and from a feminist perspective and from the South, of course. We will continue to share this path towards climate and environmental justice, which is also social. I reiterate my deepest gratitude for so many lessons learned, opportunities and achievements. I am confident that AIDA is in the best hands and ready to move on to an exciting new stage.

Climate Change, Human Rights

The IPCC's Sixth Report: the stark reality we must face with agency and hope

“Adults keep saying: “We owe it to the young people to give them hope.” But I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act”. - Greta Thumberg, addressing the World Economic Forum in January 2019.   The Intergovernmental Panel on Climate Change’s (IPCC) Sixth Assessment Report confirmed what we’ve all feared. With more refined scientific evidence than ever before, the report warns that climate change is intensifying, affecting all regions of the planet. Humanity's influence on this imbalance is now referred to as "unequivocal." As such, there’s no doubt that it’s our responsibility to confront the problem. Recent and aggressive climate events demonstrate that the world is transitioning from mere warnings to real, apocalyptic experiences. The Panel is not exaggerating. Over the last few months, floods have killed hundreds of people in some of the richest countries on the planet, and fires have ravaged thousands of hectares across the globe. Despite all this, there is still hope! And hope is our main ally in changing course. The report projected five scenarios, from the least to the most ambitious, according to the mitigation measures that humanity could implement. All of them, even the most ambitious, result in exceeding the 1.5 °C average temperature of the planet by 2040. Despite the starkness of that forecast, the report also shows that, by taking aggressive action to reduce greenhouse gas emissions, we could stabilize the increase at 1.4°C by 2100. The battle is not over, let alone lost. The most important consequences of this planetary imbalance are still uncertain and are being played out in the field. So what’s next? Drastic reductions of greenhouse gases will only be possible with systemic changes at the government and corporate levels. We also need to adjust our narratives so as to not fall into defeatism and hopelessness, because there is no scientific evidence to support surrender. Nor should we allow the environmental movement to become divided; we must be alert to the campaigns of fear and diversion practiced by our opponents. Hopelessness, defeatism and the division of our voices are precisely the winning cards of those who resist change. Given the global context, what follows are some necessary and urgent actions that will allow us to advance toward the future we need: Aiming for a rapid and just energy transition that respects human rights and includes a gender focus; as well as a new type of development that does not bulldoze nature, but cherishes and respects it. These changes should not produce fear. The technology to generate energy with minimal emissions and environmental impacts exists, is proven, and has greater potential to create jobs than the fossil fuel industry. A world powered by clean, renewable energy is a fairer, greener world. Holding the industries and companies that drive our economy accountable for what their activities leave behind. The subsidy nature has paid in the name of economic development has already exceeded what is reasonable. Projects that impact the environment, that attack the balance of nature, are no longer viable. The institutional framework and the principles of national and international law that protect the environment and human rights are on our side. We must interpret and use them for what they are: sources of binding and obligatory law.  Ensuring the protection of natural sites that have not yet been disturbed, especially those of high environmental value. Nature has the capacity to regenerate and heal itself, but we must give it a chance. Indigenous and traditional peoples, guardians of their forests and territories, play a key role in this. Advocating for the correct use of climate funds at the international level, ensuring that they work toward climate justice and not false solutions that do more harm than the disease itself. National and international financial institutions move huge amounts of money each year to address climate change. Funds for mitigation and adaptation are available and projects to be financed must comply with environmental and social safeguards. The monetary cost of not acting or not acting enough is much higher than the cost of taking immediate, effective and decisive action.  Being strategic and relying on science to take advantage of every mitigation opportunity. One example is the reduction of short-lived climate pollutants, which were specifically addressed in the recent IPCC report. These pollutants have historically lacked the attention they deserve, despite the incredible opportunity their mitigation implies. One of them is methane, whose presence in the environment is at an all-time high. Methane—the sources of which include coal mining, fracking, large dam reservoirs and intensive livestock farming—has 67 times more power than carbon dioxide (CO2) to warm the planet over a 20-year period, and its emissions cause almost 25% of that warming. Reducing these pollutants also means improving air quality in cities across the global.  Achieving ambitious results in international negotiations and honoring the treaties that protect the planet, taking advantage of the strength we have when we act in coordination. It’s true that we have been attending UN conferences on climate change for 25 years without managing to reduce emissions, but it’s also true that we have an agreement signed by all member states that is binding and that orders each country to do its part to avoid exceeding the dangerous barriers of warming. Let us not dismiss what has been achieved; rather, let’s continue to build on it. We must demand these actions and not settle for less. We must be on alert to vote for leaders who have what it takes to lead us that way.  Every small victory, every ton of CO2 that is kept in the ground, every natural space that is preserved, moves us away from the worst effects of this crisis. It's our turn, and nature must come first. We owe it to those who will inhabit this beautiful planet in the near and distant future.
