Participatory 3D mapping for DRR in Jelapan, Sindumartani, Sleman, Indonesia

As the most active volcano in Indonesia, Merapi Volcano has been threatened the life of people surrounding its slope either by primary hazard in form of pyroclastic flow and secondary hazard in form of debris flow. Therefore, disaster risk reduction (DRR) effort become an important thing to be done in the area. Integrating different stakeholders is one of the most pressing contemporary needs for enhancing disaster risk reduction. The participation of such a large range of actors in DRR allows for the integration of local and scientific knowledge as well as top-down and bottom-up actions.
Methods that used for this research is participatory three dimensional mapping (P3DM). P3DM provided a tool of dialogue between local people, scientists and local government. All stakeholders were able to contribute their knowledge on the same tool. P3DM is credible to both locals, who build the map and plot most of the information and to scientists and government representatives who can easily overlap their own data and plans. In the process, NGO/academic partners served as facilitators and moderators. Such a dialogue resulted in concerted actions including both bottom-up and top-down measures to enhance disaster risk reduction.

Results showed that from the three dimensional (3D) map, participants which consist of local community and representative of local government, could identify all aspects which needed to enhance disaster risk reduction in the study area. Those aspects are affected area, distribution of vulnerable group which consist of children, old people, people with disability, and pregnant woman, also meeting point for each neighborhood system and evacuation route which can be used to evacuate when the pyroclastic and debris flow from Merapi volcano reach the area. Those aspects were displayed in the 3D maps using clear symbol and legend which are depicted in push-pins (points), yarns (lines), and paint (polygons).
