The book finishes with a concluding chapter that identifies and brings together key insights from the earlier chapters. From a review of these key insights, four cross-cutting themes are identified: co-management as process, the relevance of power, the context of co-management and co-management as social relationships. Following discussion of these themes, a new definition is offered for co-management, inspired by the centrality of social relationships to the foundational concepts of co-management. A conceptual framework elaborates on this definition and offers a guide for the analysis and practice of co-management, one that seeks to deliver on rights and justice, as well as shared goals, accountability and legitimacy. Implications of this new, or alternative, definition of, and perspective on, co-management for practising co-management are identified and an agenda for supportive research set out.
