Launch of an Online Toolbox for Flood Risk Mitigation
Together with the UNCHR, the ETH Zurich research group SPUR created a comprehensive toolbox and learning platform for flood risk mitigation in refugee settlements.
The intensity and frequency of natural hazards are on the rise. Refugee settlements face a particular risk from such disruptive events due to their precarious built environment and socio-economic situation. In 2025, the ETH Zurich research group Spatial Development and Urban Policy (SPUR) and the external page UN refugee Agency (UNHCR) launched a external page comprehensive toolbox and learning platform for flood risk mitigation in refugee settlements. Developed to empower humanitarian practitioners, this toolbox includes a GIS tool to create flood risk maps and mitigation strategies, a compendium of flood risk mitigation measures and a participatory risk mapping methodology. The project has been jointly developed by SPUR, the UNHCR, and the external page Swiss Development Cooperation (SDC) through the external page Geneva Technical Hub (GTH).
