With a territory larger than that of Portugal and England, the city of Pará was the site of the construction of the controversial Belo Monte power plant, a project that irreversibly reshaped its ecosystem and social fabric.
Altamira, the largest municipality in Brazil, is a territory of continental dimensions in the heart of the Pará Amazon. Its vastness, which surpasses that of European nations such as Portugal and England, was the setting for one of the most controversial and impactful infrastructure projects in the country's recent history: the Belo Monte Hydroelectric Power Plant. Built on the Xingu River, a vital artery for ecosystems and traditional peoples, the plant was promised as a landmark of progress, but its legacy is a complex web of environmental devastation and social disruption.
The implementation of the project triggered chaotic urban growth, which forced displacement of tens of thousands of people and the drastic alteration of a unique river ecosystem. As detailed by Senate News Agency, controversy marked the project from its inception, with intense legal battles and protests that had international repercussions. The impacts were so severe that they led to a Federal Court decision, described by Brazil of Fact, which recognized the process of ethnocide against indigenous peoples, while the portal ClimateInfo documented how the plant “disrupted an ecosystem”, causing massive fish die-offs and forever altering life on the Xingu River.
A territory of superlatives and vulnerabilities
To understand the depth of the transformation imposed by Belo Monte, it is crucial to first understand the context. Altamira is no ordinary municipality. With an official area of 159.533,328 square kilometers, according to the IBGE, its territory is a vast mosaic of forests and rivers. This magnitude, which makes it bigger than countries like Greece, poses a colossal governance challenge. The structure of a single city government to administer an area of continental proportions creates a paradox, making the provision of basic services and environmental oversight Herculean tasks.

This condition of a territory chronically undergoverned and difficult to patrol made the region extremely vulnerable to the explosive development that the plant catalyzed. Cutting through this immensity, the Xingu River is not just a watercourse, but the ecological and cultural backbone of the region, serving as a source of life, food, and identity for hundreds of Indigenous peoples and riverside communities. The decision to dam this river represented a violent clash between two worldviews: that of engineering, which saw the river as a resource to be exploited to generate megawatts, and that of traditional peoples, who perceived it as a living and sacred entity.
Belo Monte: The Promise of Progress and the Legacy of Controversy
Presented as a pillar for Brazil's energy security, Belo Monte Hydroelectric Power Plant is largest 100% Brazilian power plant and the fourth largest in the world in terms of installed capacity. The project, whose estimated cost exceeded R$ 18 billion, was justified with a narrative of progress, promising the generation of thousands of jobs and social legacies for the region. Defended as a "cleaner" energy alternative compared to thermoelectric plants, its construction was treated as strategic and non-negotiable by the governments of the time, as highlighted in the coverage of Senate News Agency.
However, the project was born under a cloud of controversy. From its inception in the 1970s, it faced fierce opposition from a coalition of indigenous peoples, NGOs, social movements, and academics. The legal battle was intense, with the Federal Public Prosecutor's Office filing lawsuits that reached suspend the plant auction twice, highlighting serious flaws in environmental licensing. The controversy spread worldwide, attracting the attention of figures such as filmmaker James Cameron, who publicly criticized the project. Despite opposition and warnings, the Brazilian government acted with developmentalist “steamroller”, determined to win the battle at any cost.
The destructuring of an ecosystem and a people
The impacts of Belo Monte materialized as a cascade of interconnected crises. The alteration of the hydrological regime of the Xingu River, which diverted much of its flow, caused what the ClimateInfo describes the disruption of an ecosystem. The drastic reduction in water flow in the Volta Grande do Xingu, a 100-kilometer stretch of high biodiversity, resulted in a documented ecological disaster: a massive fish kill, the silting of the riverbed and the death of vast areas of forest, transformed into “tree cemeteries”.
Simultaneously, the city of Altamira was subjected to a “unprecedented social chaos”The influx of tens of thousands of workers overwhelmed the infrastructure, causing violence rates to soar and health services to collapse. At the same time, more than 30.000 people were forcibly displaced from their homes. The destruction of the river as a source of livelihood forced riverside communities and indigenous people to migrate to the outskirts of an already collapsing city, trapping them between the loss of their past and the absence of a viable future.
The energy paradox and the permanent scars of Brazil's largest municipality
The legacy of Belo Monte is marked by a profound paradox. Despite its massive installed capacity of 11.233 MW, the plant delivers a firm energy of only 4.571 MW, less than 40% of its potential, due to the seasonality of the Xingu River. This “energy paradox” questions the cost-benefit ratio of a project that required such immense social and environmental sacrifice. The ultimate irony is that, while the energy generated in the Xingu River supplies the industrial centers of the Southeast, many of the local communities that paid the highest price for the dam continue to live in the dark.
The model adopted was that of a classic “extractive enclave”, where a resource is extracted from a peripheral territory to benefit distant economic centers, treating the local population and its environment as one “sacrifice zone”The construction boom was fleeting, leaving behind a ruptured social fabric, a degraded ecosystem, and a population bearing the brunt of the losses while the energy flows away. The scars of Belo Monte in largest municipality in Brazil are a lasting testament to the unacceptable costs of a vision of development that continues to haunt the future of the Amazon.
The story of Altamira and Belo Monte raises a fundamental question about the future of the Amazon. Do you believe that large infrastructure projects like this justify their social and environmental costs? What path should Brazil take to develop the region?
