The Belo Monte Dam on the Xingu River: 10 years of impacts in the Amazon and the search for reparations
The Belo Monte Dam has caused an environmental and social disaster in the heart of the Amazon—one of the most important ecosystems on the planet.
This situation has only worsened since the hydroelectric plant began operations in 2016. The quest for justice and reparations by the affected indigenous, fishing, and riverine communities continues to this day.
In 2011, the Inter-American Commission on Human Rights (IACHR) granted them protective measures that, to date, have not been fully implemented by the Brazilian State.
Furthermore, since June of that same year, the IACHR has yet to rule on a complaint against the State regarding its international responsibility in the case.
The IACHR may refer the case to the Inter-American Court of Human Rights, which has the authority to issue a ruling condemning the Brazilian State.
After 10 years of the hydroelectric plant's operation and more than 15 years of documented human rights violations, it is time for justice to be served for the affected communities.
Read the open letter from the organizations bringing the case before the IACHR
Background
The Belo Monte hydroelectric plant—the fourth largest in the world by installed capacity (11,233 MW)—was built on the Xingu River in Pará, a state in northern Brazil.
It was inaugurated on May 5, 2016, with a single turbine. At that time, 80% of the river’s course was diverted, flooding 516 km² of land—an area larger than the city of Chicago. Of that area, 400 km² was native forest. The dam began operating at full capacity in November 2019.
Belo Monte was built and is operated by the Norte Energia S.A. consortium, which is composed primarily of state-owned companies. It was financed by the Brazilian Development Bank (BNDES), which provided the consortium with 25.4 billion reais (approximately US$10.16 billion), the largest investment in the bank’s history. Therefore, the BNDES is also legally responsible for the socio-environmental impacts associated with the hydroelectric plant.
Decades of harm to the environment and people
Human rights violations and degradation of the Amazon have been occurring since the project’s inception. In March 2011, Norte Energía began construction of the dam without adequate consultation and without the prior, free, and informed consent of the affected communities.
The construction caused the forced displacement of more than 40,000 people, severing social and cultural ties. The resettlement plan in Altamira—a city directly affected by the hydroelectric dam—involved housing units located on the outskirts, lacking adequate public services and decent living conditions for the relocated families, with no special provisions for those from indigenous communities.
Belo Monte's operations have caused a permanent, man-made drought in the Volta Grande (or "Great Bend") of the Xingu River, exacerbated by the historic droughts in the Amazon in 2023 and 2024. As a result, the deaths of millions of fish eggs were documented for four consecutive years (from 2021 to 2024), and for the past three years, there has been no upstream migration of fish to spawn and reproduce. Thus, artisanal fishing, the main source of protein for indigenous peoples and riverside communities, was severely affected: fish dropped from 50% to 30% of total protein consumed, replaced by processed foods. In summary, there was an environmental and humanitarian collapse that resulted in the breakdown of fishing as a traditional way of life, food insecurity, and access to drinking water for thousands of families, impoverishment, and disease.
Furthermore, the construction of the dam increased deforestation and intensified illegal logging and insecurity on indigenous and tribal lands, putting the survival of these communities at risk. Another consequence was the deepening of poverty and social conflicts, as well as the strain on health, education, and public safety systems in Altamira—a city ranked as the most violent in the country in 2017, where human trafficking and sexual violence increased. Violence was also reported against human rights defenders involved in the case.
In 2025, during the 30th UN Climate Change Conference (COP30), held in Brazil, the Federal Public Prosecutor’s Office labeled the damage caused by the Belo Monte dam as ecocide.

The search for justice and reparations
Over the years, the Federal Public Prosecutor’s Office in Pará, the Public Defender’s Office, and civil society organizations have filed dozens of legal actions in Brazilian courts to challenge the project’s various irregularities and its impacts. Most of the claims are still pending resolution, some for more than 10 years.
These efforts have failed because the national government has repeatedly overturned rulings in favor of the affected communities by invoking a mechanism that allowed a court president to suspend a judicial decision based solely on generic arguments such as "the national interest" or "economic order."
In the absence of effective responses at the national level, AIDA, together with a coalition of partner organizations, brought the case before the Inter-American Commission on Human Rights (IACHR) and, in 2010, requested precautionary measures to protect the lives, safety, and health of the affected indigenous communities.
On April 1, 2011, the IACHR granted these measures and requested that the Brazilian government suspend environmental permits and any construction work until the conditions related to prior consultation and the protection of the health and safety of the communities are met.
And on June 16, 2011 —together with the Xingu Vivo Para Sempre Movement, the Coordinating Committee of Indigenous Organizations of the Brazilian Amazon, the Diocese of Altamira, the Indigenous Missionary Council, the Pará Society for the Defense of Human Rights and Global Justice— we filed a formal complaint against the Brazilian State for its international responsibility in the violation of the human rights of the people affected in the case. The case was opened for processing in December 2015.
On August 3, 2011, the IACHR amended the precautionary measures to request, instead of the suspension of permits and construction, the protection of people living in voluntary isolation, the health of indigenous communities, and the regularization and protection of ancestral lands.

Current situation
The protective measures granted by the IACHR remain in effect, but the Brazilian government has not fully complied with them, reporting only on general actions. The communities have documented the ongoing violations of their rights. The situation that prompted the request for these measures—the risk to the lives, physical integrity, and ways of life of the communities—persists and has worsened with the hydroelectric plant operating at full capacity and the recent extreme droughts in the Amazon.
In addition to the impacts of Belo Monte, there is a risk of further social and environmental impacts from the implementation of another mining megaproject in the Volta Grande do Xingu. There, the Canadian company Belo Sun plans to build Brazil’s largest open-pit gold mine.
The combined and cumulative impacts of the dam and the mine were not assessed. The government excluded Indigenous peoples, riverine and peasant communities from the project’s environmental permitting process. Despite protests by Indigenous communities and other irregularities surrounding the project, the government of Pará formally authorized the mine in April 2026.
Like other hydroelectric dams, Belo Monte exacerbates the climate emergency by generating greenhouse gas emissions in its reservoir. And it is inefficient amid the longer, more intense droughts caused by the crisis, as it loses its ability to generate power.
The case before the Inter-American Commission
In October 2017, the IACHR announced that it would rule jointly on the admissibility (whether the case meets the requirements for admission) and the merits (whether a human rights violation actually occurred) of the international complaint against the Brazilian State.
Fifteen years after the complaint was filed, the affected communities and the organizations representing them are still awaiting this decision. If the IACHR concludes that human rights violations occurred and issues recommendations that the Brazilian State fails to comply with, it may refer the case to the Inter-American Court of Human Rights, whose rulings are binding.
A potential ruling by the international court in this case would set a regional legal precedent regarding the rights of indigenous and riverine peoples, public participation in megaprojects, and state responsibility in the context of the climate crisis—a precedent that is particularly relevant in light of the Court’s Advisory Opinion No. 32, which reaffirmed the obligations of States to protect the people and communities of the continent from the climate emergency.

Whales and salmon farming: how does the industry impact our gentle marine giants?
Chile is by nature a country of marine mammals. Of the 94 species of cetaceans existing in the world, 43 have their habitat in the country's waters. And just over a quarter of them are found in Patagonia. But Chile is also a country of salmon, occupying the second place in the world production, surpassed only by Norway. The overlap of the salmon industry with the habitat of these emblematic marine mammals represents a significant threat to cetaceans in Chile about which not enough is known.The recent deaths of three whales in protected areas of Chile's southern seas force us to ask ourselves why they are dying and how they are affected by the growing industry with which they share their habitat.Civil society is responding. In early November 2024, Greenpeace - together with the Kawésqar community Grupos Familiares Nómadas del Mar and with the support of AIDA - filed two criminal complaints against those responsible for the deaths of humpback whales in protected areas.These lawsuits, which have already been declared admissible, represent an unprecedented milestone in the country's criminal history, as they are the first take advantage of the amendaments made to the Penal Code by Law 21,595 on Economic and Environmental Crimes to the Penal Code to file a lawsuit for possible violations committed inside protected areas.In this context, AIDA, together with Greenpeace and the NGO FIMA - historical allies in the resistance to the expansion of salmon farming in the waters of Chilean Patagonia - commissioned a scientific report entitle “Cetaceans and Salmon Farming: Challenges for the Protection of Marine Biodiversity in Chilean Patagonia.”The report is currently available in Spanish, which lays out the available information on the impacts of salmon farming on the whales and dolphins of Chilean Patagonia. The results are alarming: serious risks have been identified, in addition to a lack of data that makes it difficult to understand the magnitude and consequences of the threats.One of the most evident impacts is the incidental capture of small and large cetaceans in farming centers. There are documented cases of entanglement and deaths, although the lack of official records makes it difficult to measure the severity of the problem.Another significant threat is the Intense maritime traffic in Patagonia, largely related to the salmon industry. Although there is no official data in Chile, there is evidence of deaths and serious injuries due to collisions between boats and whales. In addition, underwater noise from boat engines affects the health and well-being of the whales and dolphins, which depend on sound for communication and orientation.In addition to these, there are other problems of the industry, whose effects on whales and dolphins have not been adequately studied, but which we should consider while the studies are being conducted. One of these is the escape of salmonids, which compete with native species for food resources and may carry diseases that could affect smaller cetaceans in particular by reducing the availability of prey that serve as food.Microplastic pollution, 40 percent of which comes from salmon farming centers, is another under-researched environmental concern in terms of its impact on cetaceans. And the excessive use of antibiotics in Chilean salmon farming, one of the highest rates in the world, could be having negative indirect effects on the ecosystems that support these marine mammals.Finally, one of the most significant environmental impacts of the salmon farming in Chilean Patagonia is the generation of hypoxia and anoxia due to the excess of organic matter in the farming centers, coming from salmon feces and uneaten food that falls to the seabed. The decomposition of this matter consumes the oxygen in the water, creating zones in the sea where life becomes difficult or impossible.We hope that this report will fill the information gap that has become uncomfortable and even untenable in light of recent whale deaths.With this evidence, even in a scenario of limited knowledge, we will be able to encourage a governmental response towards the rapid implementation of effective protection measures for whales and dolphins in Chilean waters.Chile is a country of cetaceans, and as their guardians, we must ensure that our waters are a safe space for their development and well-being.

Organizations and communities call for intervention by the IACHR in response to the human rights impacts of mining for the energy transition
On Friday, November 15, representatives of national and regional organizations from Latin America, together with members of indigenous communities and peoples, participated in a regional public hearing before Commissioners and the Rapporteur on Economic, Social, Cultural, and Environmental Rights (REDESCA) of the Inter-American Commission on Human Rights (IACHR) to discuss the Human Rights violations that mineral extraction for the energy transition is causing on the continent.Specifically, they asked the IACHR to urge States to:Create or strengthen intangible mining-free zones in consideration of their cultural, climate, or ecosystem values.Refrain from modifying regulatory frameworks that protect the environment and indigenous peoples to facilitate investment in mining projects for the energy transition, without considering the protection of human rights.Respect and ensure the framework for protecting the right to a healthy environment, considering synergistic, cumulative, and perpetual impacts, as well as climate impacts; and implement effective mechanisms to supervise and monitor public and private actors involved in the extraction of these minerals.Strengthen their justice systems, taking into account the principles of prevention and precaution against irreparable damage to ecosystems, people, and communities. They also requested that the IACHR prepare a report examining the measures that should be adopted by the States of the region to ensure that the promotion of minerals for the transition does not lead to human rights violations, especially in communities living in areas that are highly vulnerable to the impacts of mining activities.The hearing highlighted, based on specific cases, the serious human rights issues associated with the mining of lithium, cadmium, copper, cobalt, and other minerals used in the development of renewable energy technologies.At the outset, Felipe Pino, Project Coordinator at ONG FIMA, Chile, emphasized that as the rollout of energy transition projects accelerates, there are growing calls for a just transition, which should be interpreted as a wake-up call about the lack of coherence between transition strategies and the basis for climate action: protecting people and ecosystems on the planet. “The communities most affected by the climate crisis are now threatened by strategies to combat climate change. The success of our efforts will depend on whether we are able to resolve this supposed paradox of acceleration versus justice, which is particularly evident in our region,” he said.Pia Marchegiani, Deputy Executive Director of Fundación Ambiente y Recursos Naturales (FARN), Argentina, said: “The great interest surrounding these minerals is also reflected in the enormous geopolitical dispute to gain control over them. Countries in North America, Europe, and Asia have enacted regulations to exploit these minerals and ensure their supply. International organizations such as the World Bank Group and the G20 have developed policies to ensure financing with certain safeguards in place for their use.”Marchegiani also noted that this issue has become so significant that the United Nations Secretary-General himself established a set of guiding principles to ensure justice, equity, and sustainability in the global energy transition. The first of these principles emphasizes the importance of placing human rights at the center of mineral value chains. The second highlights the need to address the transition comprehensively, with a focus on protecting the planet, biodiversity, and the environment.“It is estimated that demand for these minerals will grow exponentially in the coming years. Some forecasts suggest that global demand could quadruple by 2040 if climate agreements are fulfilled. Electric vehicles and batteries account for approximately half of the growth in this demand over the next two decades. This increase in demand translates into enormous pressure for Latin America, which already supplies 40% of the world’s copper production and 35% of lithium,” added Marchegiani.To explain the link between lithium extraction and human rights violations, Óscar Campanini, Executive Director of the Centro de Documentación e Información Bolivia (CEDIB), pointed out: “Lithium is extracted from the salt water beneath the salt flats, which requires the removal of tens of millions of cubic meters of salt water and fresh water. The salt flats in the so-called lithium triangle are located in desert areas where life is only possible thanks to fossil groundwater.”Verónica Gostissa, lawyer and activist at the Asamblea PUCARÁ in Catamarca, Argentina, said: “Since 1997, transnational companies have been extracting lithium from the Salar del Hombre Muerto, a sensitive high-altitude wetland. Due to the use of millions of liters of fresh and salt water, the companies—with the endorsement of the state—have already caused irreversible environmental damage: they have dried up the Trapiche River vega—that is, more than 5 km of river—which has died.”For her part, Lady Sandón, representative of the Environment Unit of the Consejo de Pueblos Atacameños, Chile, stated: “They are trying to secure production for 30 years to exploit lithium in fragile ecosystems such as salt flats, without having carried out consultation processes with indigenous communities, without adequate transparency, without considering those of us who live in the salt flats, arbitrarily choosing which salt flats to protect, without understanding that there is an interconnection of water.”Verónica Chávez, a member of the Comunidad de Santuario de Tres Pozos, one of more than 38 indigenous communities living in the Salinas Grandes Basin and Guayatayoc Lagoon, in the provinces of Salta and Jujuy in Argentina, said: “What we are defending is our life, that of plants, domestic and wild animals, vicuñas, llamas, etc. The lives of our ancestors, lagoons, and salt flats, which are part of our families. We all need water to live; clean water and a healthy territory. We are aware that this is not a task for the future. It is bread for today, hunger for tomorrow, and we will be sacrificed in order to extract this mineral.”Juan Sebastian Anaya, advocacy advisor at the Gaia Amazonas Foundation in Colombia, indicated that the human rights of indigenous peoples, Afro-descendants, and peasants in the Amazon are being affected by the legal and illegal extraction of minerals for the transition. “Today, there are extraction sites for rare earth elements, coltan, copper, and other strategic minerals, most of which operate without any state control… Mining activity is alien to the knowledge systems and legal order of the vast majority of Amazonian indigenous peoples,” he emphasized.Finally, Liliana Ávila, director of the Human Rights and Environment Program at the Interamerican Association for Environmental Defense (AIDA), highlighted that the testimonies reveal at least three cross-cutting elements: violations of the right to water, violations of the right to a healthy environment, and aggravated impacts on indigenous peoples and local communities. “The region has experienced decades of human rights impacts resulting from fossil fuel extraction. It is essential that new forms of energy production overcome this legacy of abuse,” she said.The hearing was requested during the 191st session of the IACHR by the Due Process of Law Foundation (DPLF), the Gaia Amazonas Foundation, and the organizations that make up the Alliance for Andean Wetlands: the Interamerican Association for Environmental Defense (AIDA), a regional organization; the Fundación Ambiente y Recursos Naturales (FARN) and Asamblea PUCARÁ of Argentina; the Centro de Documentación e Información Bolivia (CEDIB) and the Human Rights Collective Empodérate of Bolivia; ONG FIMA, Defensa Ambiental, and Fundación Tantí of Chile.

Organizations and communities alert to human rights impacts of mineral extraction for the energy transition
A public hearing before the Inter-American Commission on Human Rights will focus on the impact of the expansion and intensification of extractive operations for transition minerals like lithium and copper on communities in Latin America. Washington DC. On November 15, at a public hearing before the Inter-American Commission on Human Rights, representatives of national and regional organizations, as well as members of communities and indigenous peoples, will present updated information on how the exponential increase in the demand for and extraction of transition minerals has caused serious human rights violations as part of a transition process that is proposed only as a change in the energy matrix and is incapable of addressing inequalities in energy production and consumption, particularly in the Global South.Transition minerals like lithium, copper, cadmium, and cobalt—also called “critical” minerals—have been proposed in many global discussions as one of the main solutions to the climate crisis, as they are used in the development of technologies for the production of renewable energy, thus reducing or replacing the use of fossil fuels. A large part of these minerals are located in Latin America, in areas of great biocultural diversity.At the hearing, participants will present the main threats that mining for energy transition poses to the rights of indigenous peoples and local communities, the right to a healthy environment, access to environmental information, citizen participation, and justice. In addition, concrete cases of human rights violations in the context of mining for energy transition will be presented through testimonies.These impacts are already occurring in countries such as Argentina, Bolivia and Chile, which concentrate about 53 percent of the world's known lithium deposits in their Andean wetlands, extremely fragile ecosystems confronting water scarcity; in Chile and Peru, where 40 percent of the world’s copper is mined; and in the Colombian Amazon, where concessions, mining claims and illegal extraction of transition minerals are violating the rights of indigenous peoples.Several international organizations have spoken out about human rights abuses related to climate crisis response, particularly energy transition processes. In September, the UN Panel on Critical Minerals for Energy Transition issued a set of recommendations and voluntary principles for governments, industry and other stakeholders to ensure equitable, fair and sustainable management of these minerals. These guidelines aim to ensure that the transition to renewable energy is based on fairness and equity, and that it promotes sustainable development, respect for people, and environmental protection in developing countries.The hearing will take place during the 191st period of sessions of the Inter-American Commission. It was requested by the Due Process of Law Foundation (DPLF), the Gaia Amazonas Foundation and the organizations that are members of the the Alliance for Andean Wetlands (Alianza por los Humedales Andinos): the Interamerican Association for Environmental Defense (AIDA), a regional organization; the Fundación Ambiente y Recursos Naturales (FARN) and the PUCARÁ Assembly, of Argentina; the Centro de Documentación e Información Bolivia (CEDIB) and the Colectivo de Derechos Humanos Empodérate, of Bolivia; ONG FIMA, Defensa Ambiental and Fundación Tantí, of Chile.The hearing will be held from 9:00 a.m. to 10:30 a.m. (Washington DC time) and will be broadcast via Zoom, which requires prior registration at the following link: https://www.zoomgov.com/webinar/register/WN_dsEZdrDqSyOA8-i7ikveJQ#/registration. Quotes from representatives of organizations and communities Verónica Chávez, representative of the communities of Salinas Grandes and Laguna de Guayatayoc, Argentina:"All of us who are part of the Salinas Grande watershed are living a situation in which our rights are being affected. We hope that the IACHR can resolve this situation because it is very serious; they are damaging our territories, living beings, and nature itself." Liliana Ávila, director of the Human Rights and Environment Program at the Interamerican Association for Environmental Defense (AIDA):"The energy transition in our countries should be an opportunity to move towards more just and equitable energy production and distribution processes. The human rights framework and the role of the international protection system are fundamental in this regard. It is very important that the Inter-American Commission closely follows this process and promotes the protection of human rights." Verónica Gostissa, attorney with Asamblea Pucará of Catamarca, Argentina:"In our territory, the province of Catamarca, Argentina, we are living a serious violation of our rights, which is reflected first and foremost in the visible environmental impacts. Since 1997, lithium mining has caused significant environmental damage, including the drying up of a branch of the Trapiche River, a damage that persists to this day. Water continues to be taken from this damaged river, despite recognition of the damage by the company and government authorities. Access to public information, participation and consultation, and access to justice are also affected. For years, extractive projects have been approved without adequate procedures, and although a lawsuit filed by the Atacameños del Altiplano indigenous community resulted in a regulation, it does not meet the standards for effective indigenous consultation. In addition, more than 10 lithium projects are being developed in the same territory, the Salar del Hombre Muerto, without any cumulative and comprehensive impact assessment to date." Vivian Lagrava Flores, coordinator of the Colectivo de Derechos Humanos Empodérate, Bolivia:"Indigenous communities reject mining projects, they can even issue their resolutions and say no in the mining consultation process, but their decisions are not binding for governments. International standards are not respected, and the subjugation of territories and the imposition of mining rights are legitimized with discourses of progress and development, but it is not development from the vision of the indigenous peoples, nor from ours." Lady Sandón, representative of the Environment Unit of the Consejo de Pueblos Atacameños, Chile:"There is a lot of ignorance of the law for the native/indigenous people, which favors the state, and that is why the inhabitants of the land, by not knowing, do not enforce their guarantees. The state institutions violate the social, environmental, and cultural aspects; sometimes they use the indigenous people themselves to create divisions and to have supporters or political and mining operators who promote the change of the thinking of the genetic memory that we have as native people. I hope that we can revisit the situation of ancestral indigenous justice as a mechanism that previously established corrections so that the values and principles of ‘Buen Vivir’ are respected." Daniel Cerqueira, program director of the Due Process of Law Foundation (DPLF):"This hearing is an opportunity for the Inter-American Commission to clarify the parameters of action for both States and companies in the management of transition minerals. It is imperative to have specific obligations in this area, as human rights violations resulting from the extraction of these minerals are a reality that tends to worsen in several countries in the region." Juan Sebastian Anaya, advocacy advisor at the Gaia Amazonas Foundation (Colombia):"The indigenous governments of the Amazon exercise their territorial and environmental authority in accordance with the Law of Origin, which guides their knowledge systems and principles of relationship with the elements of the territory, such as minerals. The decarbonization of the energy matrix to maintain consumption standards in the global north should not be done at the expense of indigenous territories and the communities that protect them, govern them and make them flourish with their daily practices."Press contactsVíctor Quintanilla (Mexico), AIDA, [email protected], +52 5570522107Rocío Wischñevsky (Argentina), FARN, [email protected], +54 91159518538 Karen Arita (Mexico), DPLF, [email protected], +52 442 471 9626
