As disasters – from natural hazards to armed conflict – intensify in frequency, scale, and complexity, the need to translate environmental impact detection into decision-making and action has become increasingly urgent. Protracted conflicts and recurrent disasters, often compounded by data scarcity, underscore the need for stable, transferable, and scalable frameworks. Now in its fourth year, this session addresses this need by advancing approaches that connect environmental monitoring to real-world decisions across disaster risk reduction, humanitarian response, and recovery. We seek contributions that track initial and cascading effects of disasters across space, time, and society, reshaping natural or built environments with consequences that extend into recovery. Contributions may draw on Earth observation, in situ sensing, multi-sensor data fusion, GeoAI, and complementary qualitative or participatory methods to produce usable information across Earth systems. We especially encourage submissions that examine who these insights serve and advance decision-making under uncertainty in fragile settings.
