Purpose The purpose of this study is to optimize the location of hospitals in Gorgan, Iran, to provide desirable services to citizens in the event of an earthquake crisis. Design/methodology/approach This paper, due to target, is practical and developmental, due to doing method is descriptive and analytical and due to information gathering method is documental and surveying. In the present study, the capabilities of genetic algorithms and imperialist competition algorithm in MATLAB environment in combination with GIS capabilities have been used. In fact, cases such as route blocking, network analysis and vulnerability raster have been obtained from GIS-based on current status data, and then the output of this information is entered as non-random heuristic information into genetic algorithms and imperialist competition algorithm in MATLAB environment. Findings After spatial optimization, the hospital service process has become more favorable. Also, the average cost and transfer vector from hospitals to citizens has decreased significantly. By establishing hospitals in the proposed locations, a larger population of citizens can access relief services in less time. Originality/value Spatial optimization of relief centers, including hospitals, is one of the issues that can be of significant importance, especially in the event of an earthquake crisis. The findings of the present study and the originality, efficiency and innovation of the used methods can provide a favorable theoretical framework for the success of earthquake crisis management projects.

Purpose To reduce financial and human losses, managing risks associated with earthquakes is essential in practice. However, in using common risk management methods, experts are often faced with ambiguities that can create profound challenges for risk management. Therefore, it is necessary to develop a logical and straightforward risk assessment model to provide scientific and accurate answers to complex problems. This study aims to recommend an innovative combined method based on the probability-impact (P-I) approach and intuitionistic fuzzy set theory to identify and prioritize the essential earthquake risks associated with worn-out urban fabrics in the context of Iran. Design/methodology/approach The opinions of 15 experts in the fields of civil engineering and urban construction were gathered during brainstorming sessions. These brainstorming sessions were conducted to determine the probability of risks and the effect of identified risks. After calculating the severity of risks using the P-I approach and converting them to intuitionistic fuzzy sets, the risks were measured and prioritized based on their individual scores. Findings The study results indicated that risk of damage due to buildings’ age and flooding risk had the highest and lowest priorities in causes of financial damage, respectively. Furthermore, the risk of damage due to building quality (demolition) and building age was the most important. The risk of flooding and damage to communication networks has the lowest importance among causes of fatalities in worn-out urban fabrics. Originality/value The study findings and recommendations can be served as a policy and consultative instrument for the relevant stakeholders in the area of urban management.

Purpose Although smart city studies have increased recently, smart city discussions are made based on general concepts not specific to the region. The region-specific local smart city strategy in the built environment is key to climate resilience in the built environment in the face of natural disasters. The purpose of this paper is to focus on the smart environment, which expresses the spatial dimension of smart cities. This research defines a region-specific smart city model and revealing the role of this model in the resilience against disasters of the built environment. Design/methodology/approach The analytical hierarchy process (AHP) method was conducted in four steps. In Step 1, the authors suggested new smart environmental assessment criteria with climatic and geographical data within the scope of the collective mind of the region. In Step 2, they determined the expert group to evaluate within the scope of the AHP method and then compared the significance levels of the current and suggested smart environmental assessment criteria by the AHP method. Findings From the results, it turned out that smart urbanization processes, which are trying to relate to local characteristics, are of great importance in terms of ensuring urban resilience. The results also highlight that the existing smart environmental assessment criteria in the literature are insufficient to ensure the climatic resilience of the built environment in the face of natural disasters. Research limitations/implications The study is in an intermediary section, which has a gap in the literature due to its subject. Although it has focused on an acute problem and a current research problem, the lack of literature on the field has been a limitation. Determining the cities where the field studies would be conducted has been a major limitation. For an objective hypothesis test within the scope of the AHP method, the sample group should consist of experts working in smart city projects in cities that are in the top 3 in five different smart city rankings, where field studies are conducted. Within this limited cluster, creating a large sample group was an important limitation. Originality/value This research looks into the existing gaps of the relation between climate resilience of the built environment and the local smart city approach. This examination will foster a holistic approach in the practice of sustainable smart city in the built environment, thus reinforcing urban resilience and climate studies in the context of smart cities.

Purpose The purpose of this study is to arrive at a conceptual roadmap that may be used to analyze the impacts of post-disaster relocation on a family’s dynamics and how this, in turn, affects their resilience to future disasters. Existing literature shows that the role of the family as a social unit is often overlooked in disaster research. Ultimately, this paper seeks to elevate the place of the family and its internal dynamics as a vital determinant of family resilience in a post-disaster relocation setting. Design/methodology/approach The study is a result of a systematic literature review of four interrelated topics, namely, families in disasters; post-disaster relocation; disaster resilience and family resilience. Findings The literature review resulted in an exploration of the experiences of families amidst post-disaster relocation. Such findings were linked towards potential impacts on family dynamics, which then resulted in the study’s proposed roadmap. Originality/value The study is a novel attempt at coming up with a conceptual framework that may guide future scholars in determining the effects of family dynamics on a family’s overall disaster resilience amid post-disaster relocation. It is hoped that the use of such a framework will guide policymakers in crafting institutional reforms that take into account family cohesion in disaster relocation efforts.

Purpose This study aims to prove that land-use change plays a role in the occurrence of hydro-meteorological disasters in Central Java, especially in relation to its upstream and downstream. Design/methodology/approach The paper presents empirical findings from quantitative research using a spatial analysis and descriptive analysis. Findings The upstream and downstream area of Central Java is categorized as a rapid development area that results in changes in land use and land cover. The findings showed that there was an increasing number of hydrometeorological disasters such as floods and landslides as the impact of land-use change and rainfall conditions. Research limitations/implications Analysis of the relationship between rainfall and disaster events with more technical and specific analysis could be done in the further research. Originality/value In this study, more analysis in the context of river basin systems including upstream and downstream in different periods to examine the linkage between them have been considered and incorporated.

Purpose In October 2020, Vietnam was repeatedly hit by large storms, including Linfa, Nangka, Saudel and Molave, causing heavy rains and whirlwinds in the Central provinces of Vietnam. The heavy rain led to severe flooding in many localities. The water levels on major rivers broke records of historical flood events in 1950, 1979, 1999, 2007, 2010 and 2016. In response, this paper aims to quantify the impacts of 2020 flooding to support flood risk management activities and the relief agencies that can use the analysis. Design/methodology/approach This study demonstrates an approach to quickly map flood impacts on population, schools, health-care facilities, agriculture, transportation and business facilities and assess flood risks using available data and spatial analysis techniques. Findings The results show that all districts of Quang Binh were affected by the event, in which 1,014 residential areas, 70 schools, 13 health-care facilities, 32,558 ha of agriculture lands, 402 km road length, 29 km railway, 35 bridges on roads and 239 business facilities were exposed within flooded areas. Research limitations/implications This study is limited to direct or tangible impacts, including flooded residential areas, schools, health-care facilities, agriculture land categories, road networks and business facilities. Indirect or intangible impacts such as health, flood pollution and business disruption should be considered in further studies. Practical implications These detailed impact maps can support decision-makers and local authorities in implementing recovery activities, allocating relief and devoting human resources and developing flood risk management action plans and land-use planning in the future. Social implications This study investigates the context of flood impacts on population, schools, health-care facilities, agriculture, transportation and business facilities. Based on this research, decision-makers can better understand how to support affected communities and target the most at risk people with interventions. Originality/value This paper presents a framework to quantify the impacts of the 2020 extreme flood event using available data and spatial analysis techniques in support of flood risk management activities.

Purpose This study examines the websites of central government ministries, prefectures and municipalities to obtain a comprehensive bird’s-eye view of how they are preparing for natural disasters in the context of the novel coronavirus (COVID-19) outbreak. Design/methodology/approach This study examines the websites of central government ministries, prefectures and municipalities in Japan to survey the actual status of information dissemination on “evacuation and sheltering” in the context of COVID-19. Findings This study found that the central government issued many notices, notifications and administrative communications to prefectures, cities with public health centers and special wards, which were mainly related to opening, securing and operating evacuation centers and improving the environment. It was found that most prefectures disseminated information on both survival and living evacuation and did so from June onward, when the flood season was approaching. Among the municipalities, there were differences in information dissemination tendencies by prefecture, and it became clear that smaller municipalities were especially incapable of fully disseminating information via the Web. Research limitations/implications The data from the prefectures and municipalities surveyed in this study were collected from websites and do not necessarily represent the actual response to disaster-related evacuation in the context of COVID-19 in those areas. To clarify this evacuation, more detailed surveys are needed. Originality/value This study is unique because no research has been conducted on the response of Japanese administrative agencies to disaster-related evacuation in the context of COVID-19; the actual situation was analyzed in this study by examining central government ministries, prefectures and municipalities as administrative agencies and comparing their responses.

Purpose Nowadays, nearly the whole globe is confronting a severe threat of the COVID-19. The purpose of this paper is to explore the predictors of environmental concerns during the COVID-19 among the entrepreneurs during a second pandemic wave. Design/methodology/approach The deductive approach is applied based on cross-sectional data. An online response is gotten from entrepreneurs of Pakistan. A convenience sampling is applied to target the entrepreneurs. In total, 220 usable answers ensue for the outcome. The structural equation model (SEM) is used for the assessment of hypotheses. Findings The results of this study highlight a significant and positive effect of uncertainty of COVID-19 (U19), Perceived vulnerability (PV), Risk perception of COVID-19 (RP) and Fear of COVID-19 (F19) on environmental concerns (EC) among the entrepreneurs. Practical implications The research outcomes would provide the guidelines to policymakers and planners to develop the policies for reducing the fear, vulnerability, risk and uncertainties during the waves of the COVID-19. The findings of the study would make disaster resilience which COVID-19 creates. The results would provide the re-built environment guidelines by reducing fear, vulnerability, risk and uncertainties. Besides, the findings would help provide the knowledge and practical aspects of disasters in terms of anxiety, exposure, risk and uncertainties, which are hazardous for humans and the environment. Originality/value This study provides the empirical evidence which is the first time conducted among the entrepreneurs. Besides, this study highlights the predictors such as fear, vulnerability, risk and uncertainties towards EC in the COVID-19 scenario.

Purpose This study investigated pre-evacuation times and evacuation behaviors of vulnerable people during the 2018 flooding in Shimobara, Okayama, Japan, and the flood-triggered factory explosion, a natural hazard-triggered technological accident known as a natural-hazard-triggered technological accidents (Natech). This study examined factors that affected evacuation decisions and pre-evacuation time, estimated the evacuation time in case of no explosion and identified community disaster prevention organization response efforts for vulnerable people. Design/methodology/approach Interviews with all 18 vulnerable people who experienced the event were conducted. Multiple regression analysis was used to examine the effect of six factors on evacuation time and reasons for delayed evacuation. Findings Factors affecting evacuation decisions included the sound of the explosion, followed by recommendations from relatives and the community disaster prevention organization. Explosion-related injuries delayed early evacuation, but experience of previous disasters and damage had a positive effect on early evacuation. The explosion sound accelerated evacuation of non-injured people; however, explosion-related injuries significantly delayed evacuation of injured individuals. The Shimobara community disaster prevention organization’s disaster response included a vulnerable people registry, visits to all local households and a multilayered approach that enabled monitoring of all households. Originality/value This is the first study to examine the evacuation behavior of vulnerable people and community responses during a Natech event.

Purpose The purpose of this study is to investigate the effect of gender differences in the perception of civil engineers and construction (CEC) students toward resilience to natural hazards and extreme events in a changing climate. This study also explores to what extent CEC students perceive the status of the US infrastructure systems similar to an external evaluation model (i.e. American Society of Civil Engineers Infrastructure Report Card). Design/methodology/approach An empirical study was conducted to examine the perception of resilience among 103 females and 279 male CEC students from 15 universities across the USA. The obtained data were quantified, and different statistical methods were used to explore the similarities and differences in the gender group responses. Findings The results indicated a significant mean difference (disagreement) between male and female groups in the importance of community resilience, management and handling of natural hazards. In addition, while there was no meaningful difference between female and male students in their content knowledge, female students showed a more accurate perception about impacting factors involved. Originality/value The findings of this study offer new insight into the impacts of gender differences in the perception of resilience, which can be used to enhance the educational experience of CEC female students in areas related to community and infrastructure resilience.
