This project addresses the need to understand cultural transformations and knowledge management in Amazonian populations, focusing specifically on the Secoya and Siona communities, who belong to the Western Tukano linguistic family. The primary goal is to analyze how knowledge—including worldviews, rituals, and environmental relations—is generated and transmitted through the analysis of the Paai coca language, an agglutinative language with complex nuances. The methodology combines an exhaustive bibliographic review with intensive ethnographic fieldwork in the Sucumbíos communities (Ecuador). Data collection relies on non-directive, colloquial interviews with 'knowledge representatives,' recorded via audio and transcribed. Subsequently, the data is systematized through terminological comparison within Paai coca and with existing translations, aiming to precisely define the referentiality of the terms. Finally, the epistemic axes of knowledge will be articulated and correlated with observed cultural practices, emphasizing the crucial role of language in preserving the cultural identity of the Western Tukano.<br/><br/><b>Goal</b>: <br/>To identify the generation and transmission of knowledge within the Secoya and Siona cultures through a detailed linguistic study of the semantic fields of the Paai coca language.<br/><br/><b>Research lines</b>: <br/>Culture of the ancestral peoples
