Climate change, globalization, urbanization, and increased interconnectedness between
physical, human, and technological systems pose major challenges to disaster risk reduction
(DRR). Subsequently, economic losses caused by natural hazards are increasing in many regions of the world, which call for novel scientific approaches and new types of data collection to integrate the study of the natural processes triggering hazards, with the study of socioeconomic, political and technical factors that shape exposure and vulnerability.

This session aims to gather contributions on research, empirical studies, and observations that are useful for understanding and unravel the nexus between physical, human, and technological systems in DRR. We have identified a few examples of empirical puzzles where knowledge that is more fundamental is needed, thus contributions on the following topics are particularly welcome (but not limited to):

- Failure is a potential source of lesson-drawing, but history also offers success stories where disasters were avoided that deserve more rigorous assessment – What can we learn from comparative studies?

- Why do some societies that experience frequent natural hazards increase their resilience, while others become more vulnerable?

- Why do lowering hazard levels sometimes paradoxically lead to increased risks in some places?

- Why – despite major progress in understanding drivers of risk and developing enhanced methodologies and tools for assessing it – do we still see an increase in impacts associated with natural hazards?
