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.

What happened at the World Water Conference 2023?
By Yeny Rodríguez, Claudia Velarde and Rosa Peña* The UN Water Conference 2023, held March 22-24 in New York, was organized in response to the need to evaluate the fulfillment of global goals and targets in the areas of water and sanitation, about which there is growing concern. AIDA participated in the Conference to position key messages from Latin America and the Caribbean that should be made visible and included in the discussions and that should now be part of the fulfillment of the Water Action Agenda, which was adopted at the global meeting. What follows is our take on the important event and what we hope will come of it in the future. The Advances An agenda for urgent action The Conference concluded with the adoption of the Water Action Agenda, a plan that included 689 commitments—collected from the official sessions and side events—as well as pledges of $300 billion dollars in financing to drive them forward. The commitments cover capacity building, data and monitoring systems, and improving infrastructure resilience, among other actions. The online platform hosting the Agenda will remain open for submissions. Overall, the Conference served as a global call to protect water and the water cycle as a global common good and a fundamental human right. The international community was also alerted to the need for urgent action to address the water crisis—which translates into shortages and droughts, contamination of water sources, degradation of strategic ecosystems and serious governance problems— which today particularly affects the world's indigenous peoples, Afro-descendants and rural communities. It’s important that the commitments made be incorporated into climate discussions, since the water crisis and the climate crisis are closely interconnected. The drive for fair water governance Innovative initiatives for the protection of ecosystems and for fair water governance were launched at the Conference. Water governance involves decision-making processes, as well as institutions and power relations that influence the flow, quality, use, availability and distribution of water (fresh or salt, surface or subsurface). One such initiative was the Transformative Water Pact, built collectively by a diverse group of more than 40 civil society organizations and academia, including AIDA. The Dutch NGO Both ENDS and the International Water Knowledge Institute (IHE-Delft) spearheaded the initiative. The Pact proposes an alternative vision of water management based on the principles of environmental justice, equity and care. It proposes frameworks for action and strategic priorities to guide decision-making. It is a response to the continued overexploitation and degradation of freshwater ecosystems, human rights violations, and the extreme power imbalances that characterize current water management around the world. The Inspiring The role of women and indigenous peoples The presence of civil society at the Conference was mostly female. This both revealed the intersectional nature of the inequalities that women experience on a daily basis in their struggles for water, and vindicated their important role in water management. Women possess and transmit traditional ecological knowledge for the care of water, lead struggles in its defense, and are more frequently exposed to risks and threats to their lives. Yet their voice is often disregarded, and they are not often invited to participate in environmental decision-making spaces. Similarly, important indigenous leaders from across Latin America and the world attended the Conference. This showed how much we have to learn from indigenous ancestral practices for the care of water, as well as the decisive role that indigenous and traditional communities play in the care of 80 percent of the planet's biodiversity and in the mitigation of the climate and water crises. The parallel events in which these actors participated made the world reconsider and reevaluate what the West has understood from science, making it clear that the ancestral knowledge system of indigenous peoples is specialized and sophisticated, and therefore must be prioritized in any policy of integrated and fair water management. The unity of civil society for water justice Although largely absent from official UN spaces, civil society had a strong and inspiring presence at the Conference. Organizations, activists and water advocates from around the world held important conversations and called for effective participation, with their own voice, in these spaces. "When you ask me about this conference, I can tell you that I am optimistic, not because of the results, but because of the spirit that was born thanks to you," said Pedro Arrojo-Agudo, UN Special Rapporteur on the human rights to safe drinking water and sanitation, to a room full of civil society members and water defenders. "The UN needs the energy and legitimacy that water defenders' movements are offering and I am sure it will come." Representatives of more than 500 organizations, indigenous peoples, social movements and water defenders presented the Water Justice Manifesto with the intention of amplifying the voices of those who are not being heard and insisting that fundamental issues be placed at the center of water policies at the global, regional, national and subnational levels. Although not scheduled, movement leaders were able to read the manifesto in an official space at the Conference, which allowed for its entry into the central dialogue. What was Missing Guarantees for the effective fulfillment of commitments Although the Conference was a unique and relevant opportunity to place water-related issues on the world agenda, there is still a long way to go toward achieving effective commitments from nations, as those included in the Water Action Agenda are not legally binding. In the near future, we need these commitments to be binding, and for there to be a follow-up mechanism, indicators to measure the progress made by States in fulfilling the Agenda and – why not? – a specialized international instrument for the protection of the human right to water and sanitation. A more open and inclusive participation in the dialogue Practically all sectors echoed the need for greater participation in official UN spaces and in future conferences. This requires a broad understanding of the water crisis and the intersectional movement needed to address it justly. It implies thinking about participation based on the inclusion of stakeholders on an equal footing for dialogue and, at the same time, recognizing the individuals, communities and peoples who hold the right to water, whose voice must be taken into account in a differential manner given their interdependent relationship with water. Recognition of the valuable role of water defenders In Latin America, defending rivers, lagoons, streams, aquifers and, in general, the right to water is a risky activity. Water is a natural resource in dispute. Those who work to safeguard it for human consumption or for its recognition as an enforceable right have for years been subjected to stigmatization, threats, persecution and attacks on their lives and integrity. The water agenda must recognize the important role of water defenders, as well as promote the creation of instruments and mechanisms aimed at providing greater guarantees to those who dedicate their lives to this work. The promotion of horizontal alliances and articulations for the protection of water The protection of water is a task of all States with differentiated responsibilities and capacities. Its effective achievement requires initiatives and processes of international cooperation, alliances and articulations among States based on mutual respect and recognition. This will make it possible to reach consensual paths and prevent the repetition of dynamics of imposition. Furthermore, these articulations must recognize and respect the normative frameworks of indigenous peoples so that, based on their uses and customs, they can continue to play their fundamental role in the protection and management of water. What’s Next It’s expected that the commitments contained in the Water Action Agenda will be reviewed and endorsed internally by Latin American governments and promoted at the international level at upcoming summits and high-level meetings. It’s also expected that the importance of protecting the human right to water and sanitation will be a key theme in all international forums where progress on the Sustainable Development Goals (SDGs) is discussed, such as the SDG Summit scheduled for September, and especially at the 28th United Nations Climate Change Conference (COP28). AIDA will continue to work to protect key ecosystems, prevent industrial pressure on water, advocate for the participation of local communities in decision-making about their water sources, and defend the human right to water. *Yeny Rodríguez is an attorney with AIDA's Ecosystems Program, Claudia Velarde is Area Coordinator of Ecosystems Program y Rosa Peña is an attorney with Human Rights and Environment Program.

Strategic litigation and its role in the pursuit of justice
In La Guajira, Colombia, indigenous Wayuu and Afro-Colombian communities—accompanied by civil society organizations—initiated litigation to defend their rights to water, food security and ethnic integrity, all of which are at risk from the diversion of the Bruno stream for the expansion of El Cerrejón, the largest open-pit coal mine in Latin America. The goal of bringing this particular case to court is not only to prevent the loss of an important water source. The litigation also seeks to set a precedent in the country and on the continent for the protection of rural communities against the systematic violation of their rights. It also represents an important action in the face of the climate crisis, a global problem aggravated by the continued extraction and burning of coal and other fossil fuels. The case can be categorized as strategic litigation, also called impact litigation, which consists of selecting and filing a lawsuit in order to promote the protection of rights or changes in public policy, while achieving broad changes in society, i.e., those that extend beyond a particular case. Strategic litigation is a tool that, through the law, promotes social transformations and strengthens human rights protections. It is strategic because, based on a legal cause, it seeks to change unjust realities and position issues that are key to the formation of a democratic society. In this sense, the ultimate goal of strategic litigation is to leave a lasting mark, a judicial precedent that can be replicated. It is also strategic because it includes the use of communication strategies, social mobilization, and political advocacy to put relevant debates on the table regarding the recognition of rights. When legal actions involve local communities, they also become a tool to help strengthen their internal processes of defense. Its premises and characteristics have made strategic litigation an important means to promote the protection of key ecosystems and human rights, including the right to health and a healthy environment, and the rights of indigenous peoples, communities and groups in vulnerable situations. Components As described above, strategic litigation is consciously designed to achieve broad goals and to generate a roadmap for future litigation. It consists of many different elements, including the following: A robust legal strategy that, on many occasions, must be enriched with interdisciplinary technical and scientific arguments. A communications strategy. Social or community organizing, which means involving communities, networks and local organizations in all phases of the litigation under a perspective of active participation and collective strategy construction. A strategy to protect against scenarios of risk that the litigation may cause. Political advocacy before decision-makers. Objectives and scope Although there are many, three main objectives of strategic litigation are to: Place important debates in the public opinion. Promote social mobilization around a common cause. Strengthen the rule of law, which means that citizens invite the State and judges to recognize rights, make problems visible, and ultimately strengthen the democratic system. Strategic litigation has been especially important for struggles and causes in which it is difficult for social movements and communities to position the recognition of their rights in legislative and public policy agendas. At AIDA, we believe that all people should have full access to environmental justice, and strategic litigation has been a powerful tool to guarantee the individual and collective right to a healthy environment in Latin America. To achieve this, we select emblematic cases and projects where the strategic use of international law and scientific argumentation can set key precedents. We work closely with local organizations and allies to jointly build the litigation process, design communication campaigns, and complete risk analyses that promote the protection of all stakeholders involved in litigation.

Commitments to marine conservation: A look back at Our Ocean 2023
"Our ocean, our connection." That was the theme of the eighth Our Ocean Conference, held March 2-3 in Panama, the first Latin American country to host the annual event. The conference began in 2014 as an initiative of the U.S. State Department to draw international attention to the serious global threats to the ocean and to secure to concrete commitments for marine conservation and sustainable development. The event brought together heads of state and representatives of the private sector, civil society and academic institutions under the specific objective of highlighting the urgency of implementing effective area-based management measures as part of interconnected systems including marine protected areas, the development of a global blue economy, and approaching innovative solutions to marine pollution. An AIDA delegation attended the conference and participated in the plenary sessions and side events. The following is a summary of the event. The inspiring The focus of the conference Our Ocean is not a space for sharing knowledge about this vast ecosystem and its biodiversity. The environmental community already knows for certain that the ocean must be effectively protected as soon as possible and that there is no need to present further evidence of the multiple services it has provided to humanity for centuries. The conference brought together leaders and ministers to advance international agreements and pressure nations to commit to taking the necessary steps to protect the ocean. The power of a generation The voice of youth was prominent throughout the conference, represented for example by more than 70 members of the Sustainable Ocean Alliance (SOA), which since 2014 has built the world's largest network of new generations of people working to create solutions to the ocean's greatest challenges. Hearing youth leaders speak passionately about the importance of caring for the planet for generations to come was encouraging. As the youngest member of AIDA, I found inspiration in meeting other young people advocating for the ocean and its biodiversity. In my daily work I’m surrounded by news and numbers about the damage humanity has caused to the ocean and being part of this conference helped me see the other side of the coin. Those of us who are actively working for a healthier, cleaner and more protected ocean are part of the change and, in large part, it is thanks to us that high officials have stopped to look at the evidence and take concrete action. It is this generation that will inherit the management of the ecological crisis, whose voice deserves to be reflected in commitments to improve the way we relate to the ocean. The positive Support for seabed defense AIDA co-hosted a side event on deep-sea mining with the not-so-simple task of bringing together decision-makers to support a moratorium on deep-sea mining and seabed protection. Thanks to the impetus of a group of co-organizers—including young people from Comms Inc, The Oxygen Project, Only One and SOA—Palau President Surangel Whipps Jr. and Fiji Prime Minister Sitiveni Rabuka attended the event. High-level representatives from Latin American and European countries also attended. It was a space for dialogue between civil society and invited authorities that resulted in encouraging commitments, including France's commitment (seconded by Germany) to invest in scientific research of the seabed and to stop investments in industrial processes related to deep-sea mining. World-renowned oceanographer Sylvia Earle touched the audience with her love for the ocean and her undying commitment to its protection. Those who attended reaffirmed their commitment to the moratorium and the search for alternatives. Commitments to marine biodiversity Overall, the conference provided a unique platform for several nations to make valuable commitments. Participating government delegations made 341 commitments worth nearly $20 billion, including funds to expand and enhance marine protected areas and biodiversity corridors. In Latin America, Panama announced the expansion of Banco Volcán, a marine reserve in the Caribbean, from 14,212 to 93,000 square kilometers. With this, Panama will be protecting 54 percent of its exclusive economic zone, meeting the goal of protecting 30 percent of its territory by 2030. And Ecuador committed to protecting its first eighty nautical miles (14,800 square kilometers), allowing for only artisanal fishing. This decision positions Ecuador as a Latin American leader in marine conservation and sustainable natural resource management. Ecuador called on the other countries that make up the Pacific Marine Corridor—Costa Rica, Panama and Colombia—to take similar measures to preserve one of the most biodiverse spaces in the ocean. What's next? Nations are now expected to comply with their announced commitments. In the region, Panama and Ecuador must expand their protected territories, ensuring the adequate monitoring of biodiversity and the sustainable management of resources. Similarly, it is expected that the countries of the Pacific, Latin America and the European Union that have declared their support for halting deep-sea mining will continue with actions consistent with that position, including active participation in meetings of the Seabed Authority, supporting the moratorium or precautionary pause on extractive activity. While there is certainly a long way to go, each decision announced at the conference in favor of preserving marine biodiversity provides some hope and motivation for our work. We will continue to collaborate with governments and communities to preserve the ocean, the planet's largest and most diverse ecosystem.
