The mid-term review of Sendai Framework underscored that there are growing concerns on the acknowledgement of multi-hazard, multidimensional, and systemic nature of risk. The global risk science agenda, launched by International Science Council, United Nations Office on Disaster Risk Reduction and the Integrated Research on Disaster Risk (IRDR), also proposed the research priority on understanding the creation and perpetuation on systemic, cascading, and complex risk. Due to climate change and socioeconomic development, the systemic risk induced by natural hazards is emerging and causes significant loss and damages of livelihood, such as critical infrastructures, trades, and public health. In this regard, it is of prime pivotality to address how such risk to be defined, monitored, assessed, and reduced.
This Collection aims to advance our understanding of the concept and mechanisms of systemic risk induced by natural hazards, the materials and methods for systemic risk assessment, as well as the integrated strategies and measures on tackling systemic risk.
This Collection welcomes submissions that underline the following topics, which include, but are not limited to:
Systemic, cascading, and complex risk induced by natural hazards
Impact-based Forecasts and Warnings (IbFWs) are crucial for disaster risk reduction; however, most systems focus on single hazards, overlooking the complex interactions of multi-risk events. This siloed approach can underestimate impacts, especially when hazards occur simultaneously or sequentially. Developing multi-risk IbFW systems requires interdisciplinary collaboration, improved modelling, more impact data and clearer terminology. Analysis of historical disasters shows that multi-hazard events cause disproportionate economic losses. Advancing IbFW systems demands pragmatic innovation, robust datasets, and inclusive strategies to better reflect real-world hazard complexity.
