Programa de Aceleração do CrescimentoHalting the implementation of large dams in the Americas
The more we learn, the clearer it becomes that large dams are unsustainable energy sources.
From the Mexican highlands to the Amazon River basin, hydroelectric mega-projects are aggravating climate change, destroying sensitive ecosystems, and threatening human rights and indigenous cultures.
In October 2016, a research study from Washington State University found that the world’s reservoirs generate 1.3 percent of all greenhouse gases (more than the total emissions of Canada!), confirming the damage dams do to our climate.
Large dams have no place on our rapidly changing planet. In a time of intensifying droughts, many vulnerable hydropower-dependent countries are facing energy shortages. And as extreme weather events increase around the world, the inherent danger of large dams becomes more evident.
Throughout the construction of Belo Monte, the world’s third largest dam, we’ve seen firsthand the grave impacts these projects have on the ecosystems in which they’re built. We’ve witnessed the violations they impose on the rights of indigenous and riverine communities, whose culture and livelihoods are tied so closely to the natural world.
Yet, across Latin America and the world, large dams are still being promoted as “clean and green” energy sources; and are even receiving support from national and international climate initiatives.
That support is part of the reason more than 3,700 large dams are currently being planned or constructed worldwide, more than 400 of which have been proposed for the vital Amazon River Basin.
At AIDA, we’re proud to be part of a team leading the fight against large dams across Latin America and beyond.

Organizations call for support for communities affected by Colombia’s Hidroituango dam
Communities affected by the Hidroituango dam have denounced the murder of two of their members over the past few days. In addition, a recent obstruction in one of the dam’s tunnels means the dam is at risk of overflowing, which could cause an avalanche of mud and debris. Allies are calling on authorities to investigate the harms to local communities and provide adequate support for those affected. Two members of Movimiento Ríos Vivos Antioquia, the coalition of communities affected by Colombia’s Hidroituango Dam, have been murdered in the last several days. Hugo Albeiro George Pérez and Luis Alberto Torres Montoya were murdered on May 2 and 8, respectively, according to statements from Ríos Vivos. Members of the movement have also suffered threats, intimidation, and human rights violations due to their defense of their land and the Cauca River. At the same time, residents of towns downstream from the dam are living in fear and uncertainty this week, faced with a potential environmental catastrophe. The imminent danger is caused by an obstruction in one of the dam’s diversion tunnels that, by interrupting the flow of the Cauca River, could cause the dam to overflow with such force that it would release not just water but an avalanche of mud and debris. The Interamerican Association for Environmental Defense (AIDA), the Center for International Environmental Law (CIEL), and the International Accountability Project (IAP) express our support for Movimiento Ríos Vivos of Antioquia and the communities affected by the Hidroituango Dam in Colombia. We demand that Colombia’s environmental authorities find and punish those responsible for the murders, as well as investigate the ongoing damages caused by the dam’s construction. We also call on the national government to promptly and adequately provide support for affected families. Hidroituango, expected to become Colombia’s largest dam, will affect 12 municipalities, changing the lives of thousand of families that depend directly on the river. The project has received funding from IDB Invest, the private-sector branch of the Inter-American Development Bank. Press contact: Víctor Quintanilla, AIDA, +521 5570522107, [email protected]

Civil society organizations denounce assassination of member of Movimiento Ríos Vivos in Colombia
We stand in solidarity with the Movimiento, and we request that the Colombian State investigate this act and punish those responsible. Furthermore, we ask that Colombia adopt urgent and effective measures to stop ongoing violence against environmental defenders. The undersigned national and international organizations categorically condemn the assassination in Colombia of Mr. Hugo Albeiro George Pérez, member of Movimiento Ríos Vivos. Movimiento Ríos Vivos denounced the murder of Mr. George, who is a member of the Asociación de Víctimas y Afectados por Megaproyectos (ASVAM) El Aro—part of Movimiento Ríos Vivos Antioquia—and who, along with his family, was affected by the construction of the Hidroituango dam. The incident, in which his nephew Domar Egidio Zapata George was also killed, occurred on May 2, 2018, in Puerto Valdivia, Antioquia, in the context of regional community mobilizations against the social and environmental risks of the damming of the Cauca River. Hidroituango would be the largest dam in Colombia, with a height of 225 meters and a storage capacity of 20 million cubic meters of water. The project will affect 12 municipalities and impact thousands of families who depend on the river. The project is being financed by a loan package from IDB Invest, the private-sector arm of the Inter-American Development Bank. For defending the land and the Cauca River, Movimiento Ríos Vivos has been the target of threats, intimidation, and human rights violations. The owners of the Hidroituango project must respect human rights and act with due diligence in assessing the impacts of the dam’s construction. In response to the incident, we express our solidarity with Movimiento Ríos Vivos and with the family of Hugo Albeiro George Pérez. We request that the Office of the Attorney General of Colombia investigate this act in an expedited manner and that the appropriate court penalize those responsible. Likewise, and in the context of worsening violence against environmental defenders in the region, we demand that the government guarantee a safe setting for the work of Movimiento Ríos Vivos and to take all necessary precautions to stop the threats, intimidation, and murders against those who defend the environment and their territory. Finally, we request that environmental authorities investigate the impacts communities suffer due to the damming of the Cauca River and that the government provide assistance to the families affected by the project.

The dams that couldn’t contain Hurricane Harvey
The Addicks and Barker dams were built near Houston, Texas in an attempt to save the city from potential flooding. But the huge storage capacity of the reservoirs was not enough to contain the more than 15 billion gallons of water that Hurricane Harvey brought to the state in less than a week. Given the climatic reality of increasingly intense natural phenomena, we must ask ourselves, are dams really the best option? On the night of August 25, Hurricane Harvey appeared on the coast of Houston, quickly transforming the sprawling city into a huge flooded lake. In it’s path it left death and destruction, and the forced evacuation of more than 30,000 people. Because it is a flat city near sea level, Houston is particularly susceptible to flooding. In an effort to protect the city, the Addicks and Barker dams were built in the 1940’s. Together, the dams could hold more than 132 billion gallons of water, a capacity so large it meant that if they broke, the whole city would be submerged. With Harvey’s torrential rains, so much water has fallen that the dams have taken in more than they can hold. To avoid uncontrolled overflows, which would have been catastrophic, the authorities decided to gradually release water from the reservoirs. Even these precautionary measures, however, were not enough to prevent one of the dams from overflowing. Addicks began to overflow on Monday August 28, filling an already flooded city with more water. Barker was expected to follow suit, but ultimately did not. The spillover comes as no surprise. Since 2009, the danger posed by both dams has been well known. The dams were once located in rural areas of Harris and Fort Bend counties, surrounded by open land. But they have since been pushed to their limits, largely because of the people and buildings that have been built both upstream and downstream from the reservoirs. Before the hurricane arrived, both dams were undergoing a $75 million renovation process. But those efforts and investments weren’t enough to adequately adapt the dams to the extreme weather conditions brought about by climate change. The bottom line is that Houston has become less resilient to major climate events. In addition to the natural aging of the dams, and the intensification of climate events, half of the area’s wetlands have been replaced by concrete. Since 2001, nearly 360 thousand buildings have been constructed in the area, without adequate measures to avoid the destruction of natural wetland areas. This inadequate urban planning coupled with weak regulations has destroyed the city’s natural defenses against storms and floods. Dams and climate reality Increasingly frequent and devastating climate events are bringing into question whether the costs involved in building and maintaining large dams are worth it. Such dams are incredibly expensive to implement, let alone repair. Since 2010, 73 dams across the United States have failed. Their vulnerability to heavy rains puts in doubt their compatibility with a world shaken by the serious and uncertain effects of climate change. What’s more, the reservoirs of large dams actually aggravate climate change. Among other impacts, they flood organic matter, which emits a large amount of methane, a greenhouse gas 20 times more potent than carbon dioxide. That means that large dams actually make storms like Harvey more intense. The time has come to stop and question this dangerous cycle.
