Munduruku leaderships and researchers get together in the “Sage Gathering”, in the Dace Waptu village, indigenous land Sawré Muybu, Pará state, Amazon. Two authors from the Independent and Critical Analysis of the Impact Study and Environmental Impact Report (EIA/RIMA, in Portuguese) are present to talk and discuss with the indigenous people and their leaderships. The analysis, launched by Greenpeace Brazil, is developed by nine researchers who excel in their fields of knowledge, and identified several problems in the project Study; what compromises its efficiency on evaluating the power plant construction - which would be the largest of a series of power plants to be built on the Tapajós river.
