An Impact Chain-based exploration of multi-hazard vulnerability dynamics. The multi-hazard of floods and the COVID-19 pandemic in Romania

Abstract. In the present multi-hazard-prone times, the dynamics of vulnerability across time, space, and different hazards emerges as an intriguing but challenging research topic. Within multi-hazards, both the impacts of hazards and the mitigation strategies can augment vulnerabilities, adding layers to the complexity of multi-risk assessments. Delving into these intricacies, this study aims to i) explore the multi-hazard impacts of the co-occurrent powerful river flood events and the COVID-19 pandemic in Romania, taking as reference 2020 and 2021, and ii) to analyse the trajectories in rising vulnerability that result from impacts and adaptation options, as well as their implications. The proposed framework relies on an Impact Chain that was enhanced to include new elements (i.e., augmented vulnerabilities and derived impacts) and links (i.e., connections that describe the augmentation of vulnerability); which were also used to rank the vulnerabilities based on their augmentation. The Impact Chain draws on various data and information sources, including scientific literature, the feedback of first responders, reports, legislative documents, official press releases, and news reports. This research work makes a significant contribution to the field of DRR by broadening the purpose of the Impact Chain, transforming it into a first-hand, semi-qualitative tool for analysing vulnerability dynamics.

Short summary
This study delves into 1) compounded impacts and 2) the dynamics of vulnerability within a multi-hazard context, proposing an Impact Chain-based framework that analyses the augmentation of vulnerability. The case study refers to the flood events and the COVID-19 pandemic that affected Romania (2020–2021). The Impact Chain shows that 1) the unforseen implications of impacts, 2) wrongful action of adaptation options, and 3) inaction can set the premises for increased vulnerability.
