Huni Kuin Knowledge in the Cumaru Trade: Ethics, Economy, and Retro-prospective Futures.

This study proposes an innovative model for integrating the traditional knowledge of the Huni Kuin people regarding the sustainable management of cumaru (Dipteryx odorata) into international trade, combining social justice, cultural appreciation, and environmental protection. Recognizing that conventional supply chains often marginalize Indigenous peoples and exploit their knowledge without fair benefit-sharing, directly violating the Nagoya Protocol. This research develops an alternative model based on ethical principles of fair trade. Using a qualitative and decolonial approach, the study articulates document analysis (including a review of international regulations and case studies such as the Ashaninka) with participatory fieldwork (planned for 2025) applying the Free, Prior and Informed Consent (fpic) part with the Huni Kuin. Results show that when cumaru is managed through traditional knowledge, which integrates economic, spiritual, and ecological dimensions, it is possible to generate significant income (projected up to R$540,000/year by 2030) while preserving biodiversity and sacred rituals. More than a forest product, cumaru managed by the Huni Kuin emerges as a symbol of a bioeconomy aligned with the Sustainable Development Goals: promoting decent work and innovation (SDGs 8 & 9), reducing inequalities (SDG 10), fostering responsible production (SDG 12), and strengthening global partnerships (SDG 17). The experience of the Apiwtxa association, from the Ashaninka people, serves as a reference, showing how Indigenous governance can structure sustainable supply chains. It is concluded that integrating ancestral knowledge with international markets, when mediated by mechanisms such as ethical certifications, benefit-sharing, and protection of collective intellectual property, offers a viable path toward truly sustainable development. The study recommends the creation of a National Indigenous Origin Seal in Brazil and public policies that recognize traditional knowledge as a foundation for a regenerative economy, thus offering a practical contribution to the 2030 Agenda through a retroprospective perspective.
