Marine Protected Areas (MPAs) are a primary tool for conservation and protection of marine habitats and their associated marine life. However, 69% of MPAs are partially open to some form of fishing activity, either recreational or commercial (Turnbull, et al., 2021). In Australia, which has the second largest MPA network in the world, 75% of the total MPA area is partially protected (Roberts et al., 2020). While these partially protected areas (PPAs) provide economic and social benefits, this comes at the cost of reduced conservation benefits. Hence, the implementation of PPAs as a management tool to safeguard habitat and aquatic resources is underpinned by a tension to balance environmental, economic, and social values of multiple users.

Managing this balance requires that resource managers are cognisant of these diverse user values, and have an appropriate management framework to ensure that decision making results in socially optimal outcomes where possible. Decision making that does not considered these multi-user values can result in undesirable trade-offs, adverse environmental impacts, unnecessary complexity, ineffectiveness of management, inefficiency in resource use, social conflict and increased costs.

From the FRDC R&D priorities, access to aquatic resources, guided by good management, is fundamental for the continued delivery of economic and social benefits such as food, income, employment, recreation and cultural identity for all Australians. Optimising these benefits means sharing resources fairly using open and evidence-based processes within the limits of sustainability. As a first step to developing optimal multi-user management, there is a need to first review, and where possible, quantify the multiple values (environmental, economic, and social) that are attained through the implementation of PPAs.
