Mangrove forests are globally significant blue carbon sinks that remain critically under-governed and under threat. In Indonesia, the rapid rate of mangrove loss over the past three decades, combined with the promise of these carbon-dense ecosystems to mitigate climate change impacts, has catalyzed the world's largest replanting program. Institutional and ideological divisions between advocates of conservation and commodification approaches to mangrove governance, however, have historically compromised Indonesia's ability to meet its climate commitments. Market valuations of mangroves as blue carbon have further complicated their governance by opening up new opportunities for environmental collaboration and resource exploitation. Drawing on the concept of leverage points, this study examines how plural valuations of mangroves might be applied to sustainability interventions in Riau Province, Indonesia. Using document analysis and interviews with public, private and societal stakeholders, we examine how sector-level values translate into collaborative actions through mangrove partnerships. We posit that integrating indigenous knowledge and place-based values into mangrove policy development could help to address the existing conservation-commodification divide. As plural values are mutually transformative, we argue that recognizing areas of strategic compatibility creates space for flexible and adaptive cross-sector cooperation. Such recognition is especially important for mangrove communities, whose marginal socioeconomic position reinforces their need to remain ideologically and tactfully open to areas of compatibility with shifting market valuations, both to sustainably develop locally important resources and to avoid livelihood capture by predatory development interests.The online version contains supplementary material available at 10.1007/s11625-023-01297-1.
