摘要

Achieving the 30 × 30 target requires marine protected areas (MPAs) to expand in extent, in protection level (10% under strict protection), to be effectively managed and socially viable. Here, we assess how participatory spatial mapping approaches (i.e., Seasketch) can inform zoning processes in a multi-use MPA characterised by high conflict and low governance accountability. When combined with conflict network analysis and stakeholder-driven conservation preferences for strict protection, our results reveal strong spatial overlap between ecological vulnerability and human use and asymmetric conflict structures concentrated in nearshore areas. Stakeholder preferences did not follow a simple pro- versus anti-protection divide but reflected differentiated trade-offs linked to sectoral dependence, access needs, and perceptions of fairness. By integrating these dimensions, the approach captures diverse views on protection and supports more inclusive and context-specific planning. Our findings suggest that effective conservation depends less on expanding boundaries than on structuring how spatial trade-offs are revealed, negotiated, and aligned with governance realities.
