Marine spatial planning for the future: Using Public Participation GIS (PPGIS) to inform the human dimension for large marine parks

Marine protected area (MPA) research continues to be dominated by biophysical interests. However, understanding social data, including people's values and preferences, is critical to both effective planning and management and long-term MPA success. Having these social data in a spatial form is essential, given that MPA planning and management increasingly uses marine spatial planning (MSP) approaches to carefully locate and mediate among potentially competing uses in both space and time. An online Public Participation GIS (PPGIS) survey was used to collect spatially explicit information on stakeholder values and management preferences for Australia's remote Kimberley region. The Kimberley coast and marine environment is characterised by a multiplicity of values and preferences. Key values included biological conservation, aesthetics, recreational fishing, Aboriginal culture and heritage, and nature based tourism. Management preferences were dominated by the desire to increase conservation/protection, exclude oil/gas development and commercial fishing, and to increase Aboriginal management. The diversity of values and preferences present suggests potential for conflict over management and permitted uses. Significant associations between value and preference distribution and the Kimberley's five marine protected areas were analysed. Accessibility and respondent familiarity appear linked to value attribution. More accessible MPAs were significantly associated with recreation values while more remote MPAs were characterised by a conservation ethos and general aversion to development. Our research demonstrates that PPGIS enables documentation of spatially explicit social data across large scales, highlighting potential synergies and conflicts in values and permitted uses, in a manner that can readily integrate with ecologically based marine spatial planning processes.
