This article documents an attempt to integrate Participatory 3-Dimensional Models (P3DM) into Community-Based Disaster Risk Management (CBDRM). It particularly focuses on the islet of Divinubo, located off the island of Samar on the Pacific edge of the Philippine archipelago. The P3DM methodology proved to be useful for many reasons - it facilitates the participation of the population; raises people's awareness of their territory; allows the 3-dimensional mapping of natural and other hazards, threatened assets, vulnerabilities and capacities; better enables CBDRM to be integrated into the larger development framework; proves very useful in marginalised areas like small islands; is cheap to set up and easy to reproduce; and may providevaluable data for scientists interested in disaster research. There are several issues that turned out to be instrumental in the successful implementation of such a methodology, since neither the scientists nor the sole NGO sector were able to achieve the best results with the community on their own but had to work together. The article also emphasises that it is critical to complete a long-term confidence-building stage before attempting to implement the project.
