Prof. Dr. Gert Zöller, Institute of Mathematics, University of Potsdam, Potsdam, Germany Preface Natural hazards such as floods, earthquakes, landslides, and multi-hazard events heavily affect human societies and call for better management strategies. Due to the severity of such events, it is of utmost importance to understand whether and how they change in re- sponse to evolving hydro-climatological, geo-physical and socio-economic conditions. These conditions jointly determine the magnitude, frequency, and impact of disasters, and are changing in response to climate change and human behavior. Therefore methods are need- ed for hazard and risk quantification accounting for the transient nature of hazards and risks in response to changing natural and anthropogenic altered systems. The purpose of this conference is to bring together researchers from natural sciences (e.g. hydrology, meteorol- ogy, geomorphology, hydraulic engineering, environmental science, seismology, geogra- phy), risk research, nonlinear systems dynamics, and applied mathematics to discuss new insights and developments about data science, changing systems, multi-hazard events and the linkage between hazard and vulnerabilities under unstable environmental conditions. Knowledge transfer, communication and networking will be key issues of the conference. The conference is organized by means of invited talks given by outstanding experts, oral presentations, poster sessions and discussions. We are very pleased to welcome you to Potsdam. We hope you will enjoy your participation at the International Conference on Natural Hazards and Risks in a Changing World and have an exciting and beneficial experience. Finally, we would like to thank all speakers, partici- pants, supporters, and sponsors for their contributions that for sure will make this event a very remarkable and fruitful meeting. We acknowledge the valuable support of the Deutsche Forschungsgemeinschaft DFG (Research Training Group “Natural Hazards and Risks in a Changing World” (NatRiskChange; GRK 2043/1), as the conference would not have been possible without their help. Without your cooperation, this conference would neither be possible nor successful.
