Acesso em:.https://bdm.ufpa.br/handle/prefix/8580This study investigates the role of Indigenous associations as third sector agents in promoting autonomous and sustainable development among the original peoples of the Tucuruí Lake region, in the state of Pará, Brazil. Adopting a qualitative approach, the research is based on bibliographic and documentary review, analysis of legal frameworks and public policies, field experiences, including the author's direct participation in project development with local communities and application of the SWOT matrix. The empirical scope encompasses the Assurini do Trocará, Parakanã territories, and the Amanayé and Guajanaíra Indigenous Reserves, revealing different levels of institutional organization, internal governance, and access to opportunities. The results indicate that territories with legally established associations demonstrate greater capacity to secure resources, engage in political advocacy, and protect their lands, whereas communities without legal representation face severe restrictions in accessing public policies and mechanisms of self-management. The SWOT analysis identified community legitimacy, traditional knowledge, and collective organization as strengths; limited technical-managerial capacity, infrastructure deficits, dependence on external resources, and low visibility as weaknesses; specific public policies, funding opportunities, and inter institutional partnerships as opportunities; and territorial pressures, violence against leaders, and political instability as threats. The study concludes that institutional strengthening of these associations—combined with technical training, networking, and the valorization of ancestral knowledge—is essential to expand decision-making autonomy, foster ethnodevelopment, and ensure socio-environmental justice in the studied territories.Acesso AbertoAssociações indígenasEtnodesenvolvimentoPolíticas públicasMatriz SWOTIndigenous associationsEthnodevelopmentPublic policiesSWOT matrixCNPQ::ENGENHARIAS::ENGENHARIA SANITARIA::SANEAMENTO AMBIENTALTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
