Section 4.5: Participatory Risk Maps and Community Twin Loggers
4.5.1 Overview: Local Knowledge as Resilience Infrastructure
Effective disaster risk reduction (DRR) requires not only technological capacity, but contextualized knowledge and participatory visibility into the specific risks faced by each community. Conventional top-down risk maps often fail to reflect the lived realities, vulnerabilities, or coping strategies of marginalized populations—resulting in mismatched policies, overlooked hazards, and inefficient resource deployment.
The Participatory Risk Maps and Community Twin Loggers module embedded within Nexus Platforms transforms communities from passive recipients of risk data into active co-creators of disaster intelligence. Leveraging AI, geospatial data, ethnographic mapping, and open twin infrastructure, this module enables every ILA holder—from youth to elders—to document, verify, and visualize their risk environments in real time.
This section outlines the tools, ethics, and governance structures that power this next-generation DRR capability.
