This paper discusses the increasing trend of participatory mapping initiatives for marine spatial planning (MSP) in both developed and developing countries. While participatory mapping is commonly used for land-related planning, it is still relatively new for MSP. The paper suggests that collecting data on resource use patterns in marine protected areas (MPAs) is a good starting point for management actions. The paper recommends that specific regulations or by-laws be issued to ensure that all data collected within or around the MPA is left with the management body.
