Abstract Environmental policies that aim to enhance nature conservation, biodiversity, and well-being of Indigenous Peoples and Local Communities (IPLC) rely on knowledge integration and co-production processes that include both science and Indigenous and local knowledge (ILK) systems. While these processes are expected to safeguard the diversity of knowledge systems, uneven power relations among participants often prevent them from achieving this which can affect the legitimacy and usability of the outcomes of these processes. Using a case study in the Acre state (Brazil), where policy practitioners implemented the REDD + policy System of Incentives for Ecosystem Services in the Brazilian Kaxinawa Nova Olinda Indigenous Land, we investigate how participants manage challenges to safeguard knowledge diversity and usability during policy assessment and planning. Our findings show how, despite the use of participatory approaches, knowledge diversity ended up being compromised because policy practitioners were insufficiently attentive to power asymmetries and their implications. This, however, did not negatively affect the usability of the knowledge outcomes. Rather than focusing on the perfection of participatory methods, we call for a practical ethics that relies on culturally and ethically sensitive dialogues and that include continuous reflection. Such reflection will enable adaptation and improvisation to be able to respond to emerging power dynamics in an adequate and timely manner, thereby ensuring both the legitimacy and the usability of the outcomes of knowledge integration and co-production.

联合知识整合和共同生产以提高知识的合法性和可用性：亚马逊 SISA 政策和 Kaxinawá 土著人案例

摘要 旨在加强土著人民和地方社区 (IPLC) 的自然保护、生物多样性和福祉的环境政策依赖于包括科学和土著和地方知识 (ILK) 系统在内的知识整合和共同生产过程。虽然这些过程有望保护知识系统的多样性，但参与者之间不平衡的权力关系往往会阻止他们实现这一目标，这可能会影响这些过程结果的合法性和可用性。使用阿克里州（巴西）的案例研究，政策从业者在巴西 Kaxinawa Nova Olinda 土著土地上实施了 REDD + 生态系统服务激励政策系统，我们调查参与者如何在政策评估和规划期间应对挑战以保护知识多样性和可用性。我们的研究结果表明，尽管使用了参与式方法，但由于政策实践者对权力不对称及其影响不够关注，知识多样性最终受到了损害。然而，这并没有对知识成果的可用性产生负面影响。我们不是专注于完善参与方法，而是呼吁建立一种实践伦理，这种伦理依赖于文化和伦理敏感的对话，并包括持续反思。这种反思将使适应和即兴发挥能够以适当和及时的方式应对新兴的权力动态，
