Unexpected crises and risks affect the urban population. Critical infrastructure dependency, climate change and social dynamics have captured the attention of city decision makers across different disciplines, sectors, and scales. Addressing these challenges mandates an increase in resilience. This article presents the development of the novel European Resilience Management Guideline (ERMG) developed by the European H2020 Smart Mature Resilience (SMR) project. It encompasses five supporting tools for city resilience. The purpose of this article is threefold. First, it describes the extensive co-creation methods used to establish, validate and test the five ERMG tools as collaborations among seven city stakeholders and researchers in Europe. Second, it explains concisely the features of each tool and its use cases and applicability in the city resilience building process. Third, it shows how EMRG supports strategic management in encouraging the visibility of risk dependencies, identifying vicious loops and potential cascading effects, and promoting collaboration between stakeholders to share resources. The article concludes with a discussion of SMR standardization activities to support the transfer of this research results to wider audiences. It covers guidance on local resilience planning and supporting efforts in building and operationalization resilience at the city level. Addressing questions on how the impact of events can be managed requires a multidisciplinary approach across city sectors. For example, cities are highly dependent on CI services, and disruptions that occur in these CIs might have a profound effect on the city's ability to sustain normal functions, affecting the community at large. Not only is there a need to establish a holistic risk-assessment framework across the infrastructures to support cross-sector priorities, but these effects must also be seen in a wider city context. For example, how do organizations manage their infrastructure and variations in risk perception between stakeholders (Brown et al., 2017)? How will critical city services
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
