Brazil has suspended a decree on dredging and privatizing the Tapajós River, a major tributary of the Amazon, after protests shut down a grain terminal — but Indigenous groups are pressing for its full revocation.

Hundreds of Indigenous protesters have since Jan. 22 blockaded the Cargill grain facility in the Amazonian city of Santarém over the threats they say the decree poses to the 14 Indigenous territories and hundreds of riverine communities living along the Tapajós.

The decree was a part of an infrastructure project called the Tapajós waterway, which plans to allow private sector actors to expand sections of the Tapajós, Madeira and Tocantins rivers. The project would make the rivers navigable year-round for large barges carrying soy, corn and other grains from Brazil’s agricultural states in the Cerrado and the Amazon to ports on the Atlantic coast.

After almost three weeks of protests, the federal government suspended the decree on Feb. 6, but protesters continue to demand that the decree be revoked entirely.
