Free, prior, and informed consent (FPIC) is now a globally established norm and is a condition of equitable engagement with Indigenous peoples and local communities in biodiversity conservation. However, implementation is frequently questioned in terms of its efficacy in top-down-driven governance contexts. Local officials represent core voices often absent from mainstream discourse. Conservation practices are framed by local discourses, value frameworks, and relationships that offer critical opportunities to tailor localized consent processes. Relative to an FPIC process for a prospective World Heritage Site in Hin Nam No National Park, Laos, we examined the importance of mediation by local officials in a comanagement context. The mediation led to commitments to address long-standing community grievances and reconcile conservation and development relationships in the area. Building the capacity of local officials as critical duty-bearers helped shape rights-based conservation and development outcomes. Enhancing nonconfrontational mechanisms for rights holders to air concerns and dialogue spaces for duty-bearers to respond plays a key role in this respect.
