Natural hazards (e.g., earthquakes, volcanic eruptions, floods, landslides and ground subsidence), their cascading effects and societal risks, can strongly influence, and be influenced by human activities (e.g., migration, construction, architectural design, urban planning, forestation, deforestation, damming and drainage re-routing). The relationship between environmental risks and human behavior is dynamic in space and time. Understanding and using well this transdisciplinary interconnectedness is critical for improving disaster preparedness, urban planning, and environmental management. Investigating such complex relationships requires innovative joint analysis of the modern big earth observation data (e.g., optical, hyperspectral, GRACE, GNSS, RADAR, LiDAR), together with historical and paleo records of multi-hazards (e.g., literature, catalogue, geomorphology, and trenching), as well as anthropogenic (e.g., indigenous wisdom and tales), demographic (e.g., population, ethnicity, age), and developmental (e.g., economy, public policy) datasets. This session solicits contributions that employ earth observation (especially imaging geodesy) and interdisciplinary data sets for disaster risk reduction. We aim to encourage transdisciplinary discussions between data providers, researchers, and stakeholders, and thus welcome instrument designers, geodesists, natural scientists, social scientists, historians, anthropologists, engineers, architects, policy makers, and community workers to come together to celebrate success and highlight challenges in the integration of earth observation data in promoting resilience building and sustainable development.
