I gave this talk at the Inter-Regional Dialogue 2025, co-hosted by TCS (Trilateral Cooperation Secretariat) and UNDRR (United Nations Office for Disaster Risk Reduction). In my presentation, I shared several digital twin-based disaster management cases conducted by my company, Gaia3D. I especially emphasized the importance of open standards, open source, and open data in building effective and resilient disaster management systems.

- 3. Characteristics of South Korea - 3 - South Korea's urbanization rate is 90.7%, well above the global average. Frequent wildfires and landslides. Coastal flooding and typhoon risks. High concentration of infrastructure and assets. <Source: OpenStreetMap Tracestrack>
- 4. Why This Matters: Addressing the Disasters Climate Change 1 The climate crisis is intensifying extreme weather events—bringing heavier rainfall, longer heatwaves, and more frequent storms. Limits of Traditional Systems 3 Existing disaster response mechanisms are struggling to cope with the scale and complexity of these new threats, highlighting an urgent need for advanced solutions. Rapid Urbanization 2 Meanwhile, rapid urbanization increases vulnerability by concentrating populations and Infrastructure in hazard-prone areas, often without adequate planning. Need for Proactive Solutions 4 We require innovative, digital, and collaborative approaches to predict, prevent, and respond to disasters more effectively, safeguarding lives and infrastructure. - 4 -
- 5. Main Principles for the Digital Twin Implementations - 5 - Accessibility and sharing of critical urban and environmental data are fundamental for informed decision-making and collaborative innovation. Utilizing open-source technologies ensures transparency, fosters community-driven development, and reduces proprietary dependencies for wider adoption. Our solutions are designed to be easily scalable to accommodate the needs of diverse cities and regions globally with well known open architecture. Open Source Open Architecture Open standards guarantees interoperability between diverse systems and data formats, promoting seamless integration and scalability. Open Standards Open Data
