ABSTRACT1. Five case studies from around the world illustrate key lessons in integrating top-down and bottom-up approaches to stakeholder and community engagement in the planning and implementation of marine protected areas (MPAs).2. Community resistance to MPA proposals from centralized agencies can be addressed through effective participatory processes with consistent engagement over time, transparency, and the incorporation of benefits for communities.3. Indigenous communities in particular are becoming key actors of some conservation initiatives (e.g. MPAs) and recognition of their inherent rights, traditional knowledge and deep connections to the marine environment can become the foundations for collaborative management of MPAs.4. True participation requires empowerment for engagement, and this in turn requires education and capacity building for local people to get involved in the process of planning, implementing, and managing MPAs.5. How bottom-up and top-down approaches are used should consider the scale of the MPA (e.g. small vs. large), the geographic scenario (e.g. coastal vs. remote), the level of anthropogenic influence, the conservation objectives (e.g. species, habitats, ecosystems), the political and governance context, and specific cultural conditions, such as the presence of indigenous communities.
