Short summary
Short summary
Natural hazards like floods, earthquakes, and landslides are often interconnected which may create bigger problems than when they occur alone. We studied expert discussions from an international conference to understand how scientists and policymakers can better prepare for these multi-hazards and use new technologies to protect its communities while contributing to dialogues about future international agreements beyond the Sendai Framework and supporting global sustainability goals.

Short summary
Short summary
It remains unclear why people fail to act adaptively to reduce future losses, even when there is ever-richer information available. To improve the ability of researchers to build cumulative knowledge, we conducted an international survey – the Risk Perception and Behaviour Survey of Surveyors (Risk-SoS). We find that most studies are exploratory and often overlook theoretical efforts that would enable the accumulation of evidence. We offer several recommendations for future studies.

Short summary
The Cologne District in Germany faces frequent flooding from the Rhine and its tributaries. This study maps existing and planned nature-based solutions (NbS) to reduce flood risks. While many NbS exist along the Rhine, more efforts are needed for smaller rivers. The study recommends targeting slopes and urban areas to better manage increased flood risks linked to extreme weather and climate change.
