The objective of this study was to investigate how participatory 3D mapping can promote local intergenerational engagement for disaster risk reduction.


This investigation was carried out in the city of São Luiz do Paraitinga, Brazil, where a low-cost participatory 3D model (P3DM) was used together with secondary methods (semi-structured interviews, round tables, discussions and presentations) to engage three local focus groups (the general public, high school employees and children) to visualize and interpret local hazards, vulnerabilities, capacities and risk mitigation measures.


Participants played with a 3D model, using it to express their memories about land use changes in the city and to share their knowledge about past disasters with children that have not faced them. They identified the impacts of the previous disasters and came up with proposals of risk mitigation measures, mostly non-structural.


When applied in a way that allows spontaneous and open public participation, the participatory 3D model can be a type of disaster imagination game that gives voice to oral histories, local knowledge, and which permits the intergenerational engagement for disaster risk reduction.



This research was possible thanks to the financial support of the Coordination for the Improvement of Higher Education Personnel (CAPES) under the grant No. 88887.340300/2019-00, the São Paulo Research Foundation (FAPESP) under the grant No. 2018/06093-4, and the Brazilian National Council for Scientific and Technological Development (CNPq). The authors are also grateful to the employees and students at the State High school Monsenhor Ignácio Gióia for accepting to be part of this research, and all the other participants and local authorities, who participated during the activities.This paper forms part of a special section “Disasters, Children and Comprehensive School Safety”, guest edited by Ziqiang Han, Marla Petal, and Qiang Zhang.
