The Tapajós is one of the Amazon's great rivers — a vast, clear-watered tributary that flows through the heart of Brazil, where Indigenous communities have fished, farmed, and lived for thousands of years.
In late 2025, the Brazilian government signed Decree 12,600/2025 — a law that would have transformed the Tapajós, along with the Madeira and Tocantins rivers, into privatised industrial shipping corridors. The plan would allow companies to dredge, expand, and control sections of these ancient waterways to move commodity exports — primarily soy — to global markets.
The communities who depended on these rivers were not consulted. Under ILO Convention 169, to which Brazil is a signatory, that's not just wrong — it's illegal. Free, prior, and informed consent is a guaranteed right.
So they did something about it.
**33 days on a grain port**
On a day in January 2026, more than **800 Indigenous people from 14 communities in the Lower Tapajós region** arrived at a Cargill grain terminal in Santarém, Brazil. They weren't there to deliver cargo. They were there to shut it down — peacefully, indefinitely, for as long as it took.
The occupation lasted 33 days.
The movement, led by groups including **Movimento Tapajós Vivo**, drew national and international attention. At its front was **Alessandra Korap Munduruku** — a Munduruku leader who received the Goldman Environmental Prize in 2023, the world's most prestigious grassroots environmental award, for her years of defending the Tapajós.
'They did not ask us,' she said. 'They did not consult us. This river is our life. We will not allow it to be taken from us.'
The protesters made their demands clear: revoke the decree. No negotiations. No compromises on sovereignty over ancestral waters.
**The government blinked**
On **February 23, 2026**, after a meeting between Indigenous leaders and Brazilian government ministers, the government announced it was revoking Decree 12,600/2025.
The dredging plans for the Tapajós, the Madeira, and the Tocantins were cancelled.
The occupation ended. The river was saved.
'This is a historic victory,' said one community leader after the announcement. 'We proved that when we stand together, we cannot be ignored.'
**Why it matters**
The Amazon's rivers are not just transport routes. They are ecosystems — home to thousands of species of fish, river dolphins, caiman, and species still unknown to science. They are spiritual places. They are the water supply and the food supply for hundreds of thousands of people.
Industrialising them would have meant dredging riverbeds, introducing heavy vessel traffic, destroying floodplains, and fragmenting the Indigenous territories that border these waterways. For the communities of the Lower Tapajós, it would have meant the slow death of a way of life.
Instead, 800 people with no military, no corporate backing, and no political power walked onto a port terminal and refused to leave — until the largest government in South America changed course.
The Tapajós runs on. 🌊
