On January 22, indigenous peasants from the Lower Tapajós region and social movements carried out a large mobilization in Santarém, Pará, Brazil, occupying the port of the US monopoly Cargill. This action, reported by A Nova Democracia, denounces the privatization of the Tapajós River and the works that will affect indigenous peasants.

The federal government issued an edict on December 23, valued at R$ 74 million, for the management of the Tapajós River and the execution of dredging over the next five years, with the aim of ensuring its navigability throughout the year, even during periods of extreme drought. This measure seeks to benefit the current drainage produced by soy and other products.

Indigenous peasant peoples and social movements condemn the edict as illegal because neither the prior consultation nor the environmental study required by law were conducted. Additionally, they denounce Decree 12.600/2025, which authorizes the privatization of the Tapajós, Madeira, and Tocantins rivers, all in the Brazilian Amazonia, within the National Privatization Plan (PND). This decree favors sectors linked to the export of commodities, such as mining and agribusiness.

Technical documents from various environmental institutes indicate that the impacts of dredging include the release of heavy metals such as mercury, increased water turbidity, reduction of fish and other aquatic species, affecting the lives of peasants who depend on the river for their livelihood.
