Jirau and Santo Antonio Dams on Madeira River, Brazil

The two mega hydroelectic power plants, fueled by the Jipau and Santo Antonio dams on the Madeira River are to be completed by 2015, despite local opposition violation of human rights. In Jan 2016, Nilce de Souza Magalhães of MAB was assassinated.


Among the IIRSA projects approved in 2000- Initiative for the Integration of South American Regional Infrastructure -, there was the construction of two dams on the Madeira River, the biggest tributary of the Amazon River. The communities of Jirau and Santo Antonio, where the dams would be built, launched the Viva Rio Madeira Vivo campaign and oppose the megaprojects that would flood their territories and destroy the areas ecosystem. According to International Rivers Network, the Madeira River is the Amazons largest and most important tributary. Spanning about a quarter of the Brazilian Amazon, the Madeira Basin is a treasure trove of biodiversity, providing home to the spotted jaguar, giant otter, pink dolphin, and countless other endangered mammal species. The river teems with life – an estimated 750 fish species migrate some 4,500 km each year to spawn and feed in the nutrient-rich, muddy waters of the upper Madeira. But all this is under threat. The Brazilian government is building two massive hydroelectric dams on the Madeira. Construction of these projects–plus two additional dams upstream–would transform the Madeira into an industrial shipping canal, providing the power and transport needed to move large quantities of resources out of the Amazon—and accelerate its destruction. The project is the largest of the IIRSA.
