In Pará, Brazil’s top palm oil-producing state, Indigenous and traditional communities face mounting threats as companies expand into contested lands. Between 2021 and 2023, Mongabay’s Karla Mendes reported from the region, where the expansion of oil palm plantations has triggered pollution, deforestation and violent land conflicts. This series exposes how some of Brazil’s leading palm oil firms stand accused of pollution, land grabbing, and repression of Indigenous and Afro-Brazilian Quilombola communities. Cited in court rulings and prompting international certification suspensions, the reporting reveals the systemic failures that have enabled these abuses — and the growing calls for justice from communities on the frontlines.
