Natural hazard management supports preparedness, impact assessment, and recovery across a broad range of hazards, including floods, wildfires, earthquakes, landslides, and other geological and cascading multi‑hazard events. Earth observation missions such as CHIME, CMIR, LSTM, and ROSE‑L provide systematic and reliable measurements to detect hazard precursors, assess exposure and vulnerability—including risks associated with the green transition—and monitor interactions between hazards, infrastructure, and land use across urban and natural environments. Continuous post‑event monitoring and damage mapping deliver timely, actionable information to civil protection authorities and decision‑makers, enabling response coordination, residual risk evaluation, and recovery and reconstruction strategies that strengthen long‑term resilience and climate adaptation.
