This document discusses using Participatory 3D Modeling (P3DM) to build the resilience of coastal communities in the Pacific to climate change impacts. P3DM is a participatory mapping method that creates 3D scaled physical models with local communities. It has been effectively used by Partners With Melanesians Inc. in Papua New Guinea and elsewhere in the Pacific to help communities visualize vulnerabilities, generate discussion, and make informed planning decisions around issues like sea level rise, erosion, food security and disaster preparedness. Two example projects using P3DM in the Solomon Islands and Papua New Guinea are highlighted.
