text: A governmental proposal puts the Tupinambá of Olivença and other indigenous reclaimed lands at risk. In May 2023, the Brazilian House of Representatives approved the Marco Temporal project, which limits the demarcation of indigenous lands. It states that indigenous peoples only have claim to the land they occupied during the 1988 Constitution promulgation, meaning they can be removed from where they reside now if they cannot prove they permanently lived there in 1988. Farmers advocate for the project, since it defends private property. The project also threatens indigenous communities and their land. The Brazilian Supreme Federal Court declared the project to be unconstitutional on September 21, 2023. The declaration was overruled by the senate a week later. President Lula can still sanction or ban the project as of October 2023.
  Education
  With the land demarcation movement in progress, the Tupinambá were able to exert their constitutional right to differentiated indigenous education. As written in the 1988 Brazilian Constitution, indigenous peoples can use their mother tongue and own teaching methods in schools. The first indigenous-teaching school in Tupinambá indigenous land, the  (EEITO), was created in 2002 and opened in 2006. The second school implemented was the  (EEITSP), called  (CEITSP) since 2015, which was first an annex to EEITO and opened in Serra do Padeiro. Both indigenous and non-indigenous people attend the school. It promotes social interactions between indigenous and non-indigenous, in an effort to maintain Tupinambá identity and fight intolerance.
