This session focuses on concurrent, compounding, consecutive and cascading events and their impacts. Such events – caused by the interaction of multiple hazard, vulnerability and exposure drivers in space or time – have a multiplier effect on risks to society, infrastructure, and the environment; however, they are still overlooked in disaster risk science, where a predominant focus still remains on single hazard-risks. Recently, the topic of multi-risk has gained attention in international policy and decision-making fora, such as the UNDRR’s Global Risk Assessment Framework, the World Bank GFDRR’s Understanding Risk community, and the World Climate Research Programme (WCRP) on Extremes. Therefore, this session aims to showcase current research and foster broader exchange of knowledge between scientists and practitioners across multiple hazard communities and disciplines. We encourage contributions related to all aspects of these events, especially those that: improve understanding of physical processes; showcase new transdisciplinary methodologies for multi-risk assessment, management, and impact characterization; evaluate systemic risks; illustrate how multi-risks are integrated into operational risk management; and explore challenges and best practices of multi-risk governance.
