“…McClymont et al. (2022) built and validated the USAH model using the Delphi method with stakeholders over an 18‐month period, to produce a robust template of a generic UK city. The process for building the USAH generic template is outlined in the upper section of Figure 1.…”

“…The Abstraction Hierarchy method (Rasmussen, 1985) has a strong and diverse track record within human factors and ergonomics (HFE) (see reflections on its legacy from Naikar, 2017). Past work has discussed its potential for operationalizing urban resilience (e.g., Bedinger et al (2020);McClymont et al (2021)) and its application to a generic urban system (McClymont et al, 2022).…”

“…This section outlines how the Urban Systems Abstraction Hierarchies (USAHs) were constructed. This includes a template USAH (representing a generic UK city, summarizing work detailed in McClymont et al (2022)); then applying this template to construct a Glasgow baseline USAH, representing everyday conditions; and finally adjusting this for a Glasgow flood USAH, representing the city system during a 1:200-year fluvial flood return period. These steps are outlined in Figure 1.…”

Climate change will mean cities are exposed to more frequent short‐term shocks such as floods. City‐scale resilience is achieved by understanding how these shocks interact with longer‐term stressors (e.g., social inequality). The Urban Systems Abstraction Hierarchy (USAH) has been developed for this purpose. In this paper, Glasgow (UK) is used as a case study application, to demonstrate how resilience theory can be operationalized through the application of the USAH. Results demonstrate how the USAH can quantify interdependencies between tangible physical entities in the city and intangible outcomes that monitor city stressors, and specifically how these outcomes change in response to a 1:200‐year fluvial flood return period in Glasgow. Resilience concepts such as multifunctionality, redundancy and diversity are applied to interpret the results and their implications for longer‐term resilience in Glasgow. The findings from the application of the USAH show that the outcome Social equality and equity is influential for longer‐term resilience in Glasgow, whilst Reliable communications and mobility is an important outcome for flood resilience.

“…Further, it has to be acknowledged that not all aspects can be included in an integrated approach and in each case the most significant hazards need to be identified and addressed. The latter requires detailed multidisciplinary analysis that reflects the full range of interactions in the system that is impacted, such as that proposed at city level by McClymont et al (2022). Such approaches need to include qualitative analysis based on case studies and experience, along with a quantitative approach based on analytical and AI (Artificial Intelligence) methods for identifying the key influences.…”

Hydrological hazards (“hydro-hazards”) are defined as extreme events associated with the occurrence, movement and distribution of water, specifically resulting in floods and droughts. As a result of global climate change these hazards are expected to change in the future, with areas of the globe becoming “hotspots” for the intensification of these extremes. This paper is the first global review of the state- of-the-art research on hotspots for floods and drought. The work follows a systematic literature review of published research, and analyses and categorizes the results of 122 published papers after a methodical screening process. The analysis highlighted the geographical areas where increasing hazards are anticipated (e.g., Europe for both floods and droughts), and those areas of the globe where no significant research has been published (e.g., Russia). The methods used to undertake the research are analyzed and new trends identified. Potential avenues for future research are highlighted, including the incorporation of uncertainty analyses into hydro-hazard assessments, the consideration of multi-hazards and their interconnections, and finally the consideration of dynamic vulnerability and exposure in conjunction with changing hydro-hazards to understanding future risk.

“…During the study of community anti-seismic resilience, Michel et al(2012) innovatively established a functional model of infrastructure resilience probability and resilience recovery time to obtain city infrastructure resilience through quantitative calculation and analysis. With the continuous accumulation of city big data and the continuous progress of cloud computing technology, it is promising that the quantitative evaluation mode, urban systems abstraction hierarchy (USAH), and simulation dynamic analysis method and technology of resilience city can be realized (Mcclymont et al, 2022).…”

Resilience city, a new concept of city sustainable development, becomes one of the important subjects of high-quality development research. Compared to the traditional urban disaster mitigation approach, resilient cities focus more on the organizational capacity and coordination within the urban systems. Taking Guangzhou metropolitan area as an instance, which is featured a highly developed economy and society and frequently happened hazards and disturbances, the paper constructs an evaluation index system from four city subsystems, including economy, society, ecology, and engineering. Meanwhile, by applying the methods of global entropy weight, variation coefficient, geographic information system, and obstacle degree model, the paper explores the time changes, space evolution, and obstacle degree factors of city resilience in the Guangzhou metropolitan area from 2010 to 2020. The research results show that: (1) There is a significant change in the time difference of city comprehensive resilience of the Guangzhou metropolitan area. The resilience of each city’s resilience subsystem has grown steadily, of which the development level of economic resilience, social resilience, and engineering resilience has been steadily improved, and ecology resilience level shows a slight decline among a steadily increasing. (2) The overall city resilience of the Guangzhou metropolitan area shows a radial pattern taking Guangzhou as the core, of which the city economy, society, and engineering resilience grades mainly show a medium and low resilience level, the ecology resilience mainly shows a medium and high resilience level, and the general performance of resilience space distribution level is high in the southeast and low in the northwest. (3) Social resilience and ecological resilience are the main driving subsystems in the early and late stages of city resilience development in Guangzhou metropolitan area during the research period, and engineering resilience is the main constraint subsystem. (4) Water and soil loss control area and population density are the main obstacle factors in the early and late stages of city resilience in the Guangzhou metropolitan area. The density of the city drainage pipeline and the total import and export volume are the basic resilience barrier factors. The paper analyzes the spatial-temporal pattern and influencing factors of city resilience in the metropolitan area from a multi-dimensional perspective, provides a new thinking and analysis framework for the management and sustainability of city resilience in the metropolitan area, and provides a reference for the coordinated development of the metropolitan area.
