The PACC Vanuatu project team identified participatory three-dimensional modelling (P3DM) as a valuable tool to facilitate community participation and decision making in the project.

P3DM involves the building of threedimensional (3D) relief maps by communities, combining local knowledge of geography and land use with georeferenced data. The map then forms the basis for discussion and decision making on project interventions.

For the PACC project, the purpose of using the P3DM approach was to facilitate the development of communityowned and consensual management and adaptation plans, and also to help the communities to better understand their island ecosystems, and the relationships between terrestrial and marine ecosystems. The exercise also allowed the communities to share their social, cultural and economic experiences with the adverse effects of climate and natural disasters in the area, and their coping strategies
