INTEGRATION OF MULTIPLE CONSERVATION OBJECTIVES IN MARINE PLANNING FOR CORAL REEFS
Decision-makers focus on representing biodiversity, maintaining connectivity, and strengthening resilience to climate warming when designing marine protected area (MPA) networks. However, the development of MPAs intended to achieve these goals might fail if multiple conservation objectives are not adequately formulated from the outset of marine planning. By using Brazilian coral reefs as a case study, we devised conservation objectives for biodiversity, connectivity and resilience to climate warming and we determined the extent to which existing MPAs achieve these objectives. In doing so, we explored interactions between different sets of objectives and evaluated the consequences of pursuing single objectives in marine planning, leaving other objectives to be achieved incidentally. We found that MPAs in Brazil are more effective for biodiversity than for connectivity and resilience to climate warming. Moreover, we identified extensive misalignment between existing MPAs and priority areas that strategically achieve a well-balanced set of objectives. Although better synergies between objectives were found when planning directly for biodiversity, multiple-objective approaches will provide the best opportunities for integrated MPA design. Our analyses reinforce the utility, feasibility, and value of setting multiple conservation objectives, support efforts to expand MPAs for Brazilian coral reefs, and yield insights for planners of coral-reef MPAs elsewhere.
