Participatory governance is crucial to ensure transition. The development of the blue bioeconomy is no exception, and requires participatory governance models, especially to foster and frame niche local experimentation in the field of blue sustainability. The principle of participatory governance needs to be more systemically integrated in all local and transnational transition projects in Panoramed and future transnational funding programmes. In this report, we develop a participatory governance model based on a review of the literature, best practices of successful cases collected through a Panoramed online survey and existing Interreg examples which are already developing this governance component.
