Sônia Guajajara, the Minister of Indigenous Peoples and a federal deputy (PSOL-SP), called for the advancement of indigenous territorial rights in Brazil this week.

These efforts aim to prevent legislative setbacks and ensure the legal protection of ancestral lands against encroaching interests. The struggle over land demarcation remains a central conflict in Brazilian environmental and human rights policy.

During an interview with Jornal da Manhã on Saturday, Guajajara criticized the "marco temporal," a legal thesis that limits land claims to territories occupied by indigenous groups on the date the Brazilian constitution was signed [1]. Guajajara said, "O marco temporal é inconstitucional e coloca em risco a demarcação de terras indígenas" [2].

Guajajara has continued this advocacy across various public forums, including the Gaviões da Fiel parade in São Paulo [3]. She said that the executive branch must implement integrated actions to safeguard indigenous reserves and meet the demands of original peoples [1], [3].

Beyond legal battles, the minister emphasized the necessity of indigenous presence within the government. Speaking at the 22nd edition of the Acampamento Terra Livre, Guajajara said, "Precisamos de mais representantes indígenas na política para garantir nossos direitos territoriais" [4].

Her platform also bridges traditional knowledge with modern research to combat climate change. During her participation in the 2026 Web Summit Rio, she said that science and ancestral knowledge are fundamental for preserving biodiversity [5]. These efforts align with broader goals of land recovery, such as the demarcation of 33,900 hectares of indigenous land [6].

Guajajara continues to push for a governance model where indigenous leadership is not merely consultative but integrated into the legislative process to prevent the erosion of constitutional protections [4].

“"O marco temporal é inconstitucional e coloca em risco a demarcação de terras indígenas."”

The focus on the 'marco temporal' represents a critical legal battle over the definition of land ownership in Brazil. If the thesis is upheld, it could freeze thousands of pending land claims, potentially displacing indigenous communities and increasing deforestation. Guajajara's push for integrated executive action and increased political representation suggests a strategy to move beyond judicial appeals by embedding indigenous authority directly into the state's administrative structure.
