Marine Protected Areas (MPAs) are a critical part of the marine resource management community’s toolbox in seeking a sustainable and vibrant global ocean system. The processes of community engagement with MPAs, however, are rooted in pre-existing power dynamics inherent in environmental governance systems and influenced by historical contexts of colonialism. Marine governance has historically operated in a top-down manner, imposing exclusionary forms of conservation on local communities without affording them equitable power in the process. Meaningful engagement of community members in MPAs has been suggested as one of the key enabling conditions that drive successful marine protection. Specifically, participatory science methods have the potential to engage local communities, elevate local voices and expertise, and strengthen both local communities and scientific learning. This systematic scoping review assesses the peer-reviewed literature to understand the quality and nature of participatory science methods that have been used to engage communities in MPAs. The review highlights that, while participatory science methods are not uncommon in MPAs, they seldom challenge existing power dynamics. The results of this review show that power in MPA processes related to participatory science is generally retained by conventional researchers and MPA managers. Based on these findings, the authors provide recommendations to marine resource management researchers and practitioners to help the ocean governance community support greater power sharing with local communities through equitable and locally appropriate participatory science methods.
