Abstract
Purpose
The current fire protection measures in buildings do not account for all contemporary fire hazard issues, which has made fire safety a growing concern. Therefore, this paper aims to present a critical review of current fire protection measures and their applicability to address current challenges relating to fire hazards in buildings.
Design/methodology/approach
To overcome fire hazards in buildings, impact of fire hazards is also reviewed to set the context for fire protection measures. Based on the review, an integrated framework for mitigation of fire hazards is proposed. The proposed framework involves enhancement of fire safety in four key areas: fire protection features in buildings, regulation and enforcement, consumer awareness and technology and resources advancement. Detailed strategies on improving fire safety in buildings in these four key areas are presented, and future research and training needs are identified.
Findings
Current fire protection measures lead to an unquantified level of fire safety in buildings, provide minimal strategies to mitigate fire hazard and do not account for contemporary fire hazard issues. Implementing key measures that include reliable fire protection systems, proper regulation and enforcement of building code provisions, enhancement of public awareness and proper use of technology and resources is key to mitigating fire hazard in buildings. Major research and training required to improve fire safety in buildings include developing cost-effective fire suppression systems and rational fire design approaches, characterizing new materials and developing performance-based codes.
Practical implications
The proposed framework encompasses both prevention and management of fire hazard. To demonstrate the applicability of this framework in improving fire safety in buildings, major limitations of current fire protection measures are identified, and detailed strategies are provided to address these limitations using proposed fire safety framework.
Social implications
Fire represents a severe hazard in both developing and developed countries and poses significant threat to life, structure, property and environment. The proposed framework has social implications as it addresses some of the current challenges relating to fire hazard in buildings and will enhance overall fire safety.
Originality/value
The novelty of proposed framework lies in encompassing both prevention and management of fire hazard. This is unlike current fire safety improvement strategies, which focus only on improving fire protection features in buildings (i.e. managing impact of fire hazard) using performance-based codes. To demonstrate the applicability of this framework in improving fire safety in buildings, major limitations of current fire protection measures are identified and detailed strategies are provided to address these limitations using proposed fire safety framework. Special emphasis is given to cost-effectiveness of proposed strategies, and research and training needs for further enhancing building fire safety are identified.

Abstract
Purpose
The purpose of this paper was to develop an integrated framework for assessing the flood risk and climate adaptation capacity of an urban area and its critical infrastructures to help address flood risk management issues and identify climate adaptation strategies.
Design/methodology/approach
Using the January 2011 flood in the core suburbs of Brisbane City, Queensland, Australia, various spatial analytical tools (i.e. digital elevation modeling and urban morphological characterization with 3D analysis, spatial analysis with fuzzy logic, proximity analysis, line statistics, quadrat analysis, collect events analysis, spatial autocorrelation techniques with global Moran’s I and local Moran’s I, inverse distance weight method, and hot spot analysis) were implemented to transform and standardize hazard, vulnerability, and exposure indicating variables. The issue on the sufficiency of indicating variables was addressed using the topological cluster analysis of a two-dimension self-organizing neural network (SONN) structured with 100 neurons and trained by 200 epochs. Furthermore, the suitability of flood risk modeling was addressed by aggregating the indicating variables with weighted overlay and modified fuzzy gamma overlay operations using the Bayesian joint conditional probability weights. Variable weights were assigned to address the limitations of normative (equal weights) and deductive (expert judgment) approaches. Applying geographic information system (GIS) and appropriate equations, the flood risk and climate adaptation capacity indices of the study area were calculated and corresponding maps were generated.
Findings
The analyses showed that on the average, 36 (approximately 813 ha) and 14 per cent (approximately 316 ha) of the study area were exposed to very high flood risk and low adaptation capacity, respectively. In total, 93 per cent of the study area revealed negative adaptation capacity metrics (i.e. minimum of −23 to <0), which implies that the socio-economic resources in the area are not enough to increase climate resilience of the urban community (i.e. Brisbane City) and its critical infrastructures.
Research limitations/implications
While the framework in this study was obtained through a robust approach, the following are the research limitations and recommended for further examination: analyzing and incorporating the impacts of economic growth; population growth; technological advancement; climate and environmental disturbances; and climate change; and applying the framework in assessing the risks to natural environments such as in agricultural areas, forest protection and production areas, biodiversity conservation areas, natural heritage sites, watersheds or river basins, parks and recreation areas, coastal regions, etc.
Practical implications
This study provides a tool for high level analyses and identifies adaptation strategies to enable urban communities and critical infrastructure industries to better prepare and mitigate future flood events. The disaster risk reduction measures and climate adaptation strategies to increase urban community and critical infrastructure resilience were identified in this study. These include mitigation on areas of low flood risk or very high climate adaptation capacity; mitigation to preparedness on areas of moderate flood risk and high climate adaptation capacity; mitigation to response on areas of high flood risk and moderate climate adaptation capacity; and mitigation to recovery on areas of very high flood risk and low climate adaptation capacity. The implications of integrating disaster risk reduction and climate adaptation strategies were further examined.
Originality/value
The newly developed spatially explicit analytical technique, identified in this study as the Flood Risk-Adaptation Capacity Index-Adaptation Strategies (FRACIAS) Linkage/Integrated Model, allows the integration of flood risk and climate adaptation assessments which had been treated separately in the past. By applying the FRACIAS linkage/integrated model in the context of flood risk and climate adaptation capacity assessments, the authors established a framework for enhancing measures and adaptation strategies to increase urban community and critical infrastructure resilience to flood risk and climate-related events.

Abstract
Purpose
The impacts and costs of natural disasters on people, properties and environment are often severe when these occur on a large scale and with no warning system in place. The lack of deployment of an early warning system (EWS), low risk and hazard knowledge and impact of natural hazard experienced by some communities in the UAE have emphasised the need for more effective EWSs. This work focuses on developing an integrated framework for EWSs for communities prone to the impact of natural hazards to reduce their vulnerability and improve emergency management arrangements in the UAE.
Design/methodology/approach
The essential elements of effective EWS were identified through literature review to develop an integrated framework for EWS. Semi-structured interviews and questionnaires were also used to identify and confirm hindering factors to deployment of effective EWSs in Abu Dhabi and Fujairah Emirates, while areas that require further development were also identified through this means.
Findings
The outcome of this research revealed that the warning for natural hazards in the UAE lacked the required elements for effective EWS, whereas the elements which are present are insufficient to mitigate the impacts of natural hazards. The information in this work emphasises the need to improve two elements, and to develop the other two essential elements of EWS in the UAE.
Originality/value
The outcome of this research revealed that the warning for natural hazards in the UAE lacked the required elements for effective EWS, whereas the elements which are present are insufficient to mitigate the impacts of natural hazards. The information in this work emphasises the need to improve two elements and to develop the other two essential elements of EWS in the UAE.

Abstract
Purpose
Cultural heritage (CH) sites are not only important components of a country’s identity but can also be important drivers of tourism. However, an increasing number of extreme events associated with the impacts of climate change, natural hazards and human-induced threats are posing significant problems in conserving and managing CH worldwide. Consequently, improved climate change adaptation and enhanced hazard/threat mitigation strategies have become critical (but to-date under-researched) considerations. The purpose of this paper is to identify the key hazards and threats to CH sites, the most common types of risks to CH and the strategies being adopted to mitigate or even eradicate those risks.
Design/methodology/approach
This paper reviews 80 CH case studies from around the world, which have been presented at a UNESCO International Training Course between 2006 and 2016. The case studies cover 45 different countries and provide practical insights into the key challenges being encountered in a variety of “at risk” locations.
Findings
The analysis assesses the key natural hazards and human-induced threats to the sites, an overview of the typical impacts to the tangible components of heritage and identifies the types of strategies being adopted to mitigate the risks, some of which could be transferred across cultural and geographical contexts.
Originality/value
The paper provides a wealth of useful information related to how challenges faced by CH sites might be addressed in the future.

Abstract
Purpose
Natural hazards such as floods, wildfires and droughts disrupt communities, their economies and environments, and cost millions every year. The existing literature on hazard mitigation shows that community resilience is best achieved when mitigation strategies are integrated with land use and comprehensive planning. The purpose of this paper is to evaluate the strengths and weaknesses of hazard mitigation in local comprehensive plans.
Design/methodology/approach
The analysis uses a new plan evaluation protocol that integrates flood, wildfire and drought mitigation to evaluate the plans of the six largest and fastest growing counties in Arizona.
Findings
The study finds that counties do not plan equally well for all hazards, that they tend to plan better for droughts than wildfires and floods, and indicates the need to improve hazard information in plans to support the adoption of mitigation goals, objectives and strategies.
Research limitations/implications
The research is based on a small sample of comprehensive plans. It focuses on the content of plans rather than the causes that may explain this content or the implementation of the strategies included in the plans. Future research will thus need to analyze larger numbers of plans to identify the determinants of the degree to which comprehensive plans integrate hazard mitigation; and evaluate whether strategies advanced in plans are integrated with other planning documents and implemented.
Practical implications
The paper makes recommendations to improve the plans evaluated and to guide planners as they develop or revise comprehensive plans in other jurisdictions subject to natural hazards.
Originality/value
The key methodological contribution of the paper is the new plan evaluation protocol designed to assess the wildfire, drought and flood mitigation provisions in comprehensive plans.

Abstract
Purpose
The rapid deterioration of the earth’s natural ecosystems are increasing the risk of human morbidity and mortality worldwide. Hydrometeorological hazards are concentrating contaminants from the damaged environment and exposing large vulnerable populations to life threating illnesses and death. This study performed a retrospective health risk assessment on two recent events where such impacts unfolded, namely, the 2015 south east Equatorial Asia smoke haze disaster and the 2016 Melbourne thunderstorm asthma epidemic. The purpose of this paper is to test if the characterisation of health risk warranted earlier and more effective risk reduction activities prior to the disasters occurring.
Design/methodology/approach
A retrospective health risk characterisation assessment was performed combing United Nations International Strategy for Disaster Risk Health Aspect in Disaster Risk Assessment (2017) framework with a thematic and targeted word literature review to identify the level of risk knowledge prior to each event. A risk characterisation matrix was then created to characterise the health risk of each hazard event.
Findings
The 2015 south east Equatorial Asia smoke haze disaster risk assessment was characterised as “extreme” health risk and the 2016 Melbourne thunderstorm asthma epidemic was characterised as “high” health risk.
Practical implications
Reaching the goals of the Sendai Framework require strategies and plans which urgently address the catastrophic level of mortality risk posed by exposure to environmental contaminants.
Originality/value
Innovative approaches and partnerships are necessary to mitigate the risk from the deteriorating health of the environment and natural ecosystems, along with disaster response initiatives that reduce exposure of vulnerable people on a large scale.

Abstract
Purpose
The overall objective of this study is envisaged to provide decision makers with actionable insights and access to multi-risk maps for the most in-danger stave churches (SCs) among the existing 28 churches at high spatial resolution to better understand, reduce and mitigate single- and multi-risk. In addition, the present contribution aims to provide decision makers with some information to face the exacerbation of the risk caused by the expected climate change.
Design/methodology/approach
Material and data collection started with the consultation of the available literature related to: (1) SCs' conservation status, (2) available methodologies suitable in multi-hazard approach and (3) vulnerability leading indicators to consider when dealing with the impact of natural hazards specifically on immovable cultural heritage.
Findings
The paper contributes to a better understanding of place-based vulnerability with local mapping dimension also considering future threats posed by climate change. The results highlight the danger at which the SCs of Røldal, in case of floods, and of Ringebu, Torpo and Øye, in case of landslide, may face and stress the urgency of increasing awareness and preparedness on these potential hazards.
Originality/value
The contribution for the first time aims to homogeneously collect and report all together existing spread information on architectural features, conservation status and geographical attributes for the whole group of SCs by accompanying this information with as much as possible complete 2D sections collection from existing drawings and novel 3D drawn sketches created for this contribution. Then the paper contributes to a better understanding of place-based vulnerability with local mapping dimension also considering future threats posed by climate change. Then it highlights the danger of floods and landslides at which the 28 SCs are subjected. Finally it reports how these risks will change under the ongoing impact of climate change.

Abstract
Purpose
Every year, hundreds of people have died and thousands have been injured because of insufficient management of well control at oil and gas drilling and production sites. Major causes which have been reported in previous studies included uncontrollable blowouts and failure of blowout preventers because of insufficient safety practices. These onshore and offshore blowout disasters not only harm the work force but also critically affect the environment and marine life. In this research paper, a detailed quantitative survey and qualitative risk assessments (RA) have been carried out for assessing the potentially hazardous activities associated with well control along with their appropriate controls and risk reduction factors and mitigating measures in Middle East and south East Asian countries.
Design/methodology/approach
The sequential explanatory research design has been adopted in this study. Whereas, descriptive statistical approach has been used for the quantitative data analysis of this study. While, in-depth interview approach has been used for qualitative data collection. Similarly, what-if analysis method has been adopted in this study for the identification of effective safety and health risk mitigating factors because it provides in-depth information from health and safety environment experts.
Findings
The cumulative quantitative results based on the response from Saudi Arabian drilling industry have indicated that the well control operation is highly hazardous then Malaysian and Pakistani oil and gas industries. Likewise, findings from what-if analysis approach demonstrate that the drilling crewmembers have repetitively faced life threatening hazards which occur (safety and chemical) during well control onshore and offshore operation because of oil base mud, confined space at site, pinch points and falling during working on blow out preventers. According to the overall result, respondents have highly recommended engineering and administrative hazard controlling factors as most suitable for the elimination of safety and chemical hazards during well control activities.
Practical implications
Besides, the developed methodological framework for the identification of suitable hazard controls can also be effectively used for potential hazards reorganization and identification of suitable hazard controls for other drilling and production industries and regions for accident prevention and safety and health management.
Originality/value
This is a first comparative research study which has been carried out in Malaysian, Saudi Arabian and Pakistani onshore and offshore oil and gas industries for well control health and safety management and reorganization of most effective hazards mitigating factors at drilling sites.

Abstract
Purpose
This paper seeks to further develop a model of natural hazard preparedness by examining the role of attitudes to natural hazards and their mitigation and social norms. It aims to examine whether social‐cultural factors influence the decisions people make regarding their relationship with natural hazards.
Design/methodology/approach
Survey data were collected from 156 residents in Napier, New Zealand. A cross‐sectional design was used. Data were analysed using the AMOS 5 structural equation modelling program.
Findings
Positive attitudes to hazard mitigation, existing in a social context that advocates adopting protective behaviours, belief in the effectiveness of personal mitigation (outcome expectancy) and good problem solving (action coping) skills increase the likelihood of adopting protective measures for earthquakes. The research identified how attitudes and social norms influence the perception of hazards and how people make preparedness decisions.
Research limitations/implications
Further research is needed to examine how hazard attitudes are formed, sustained and organized, as well as how they can be changed to facilitate the sustained adoption of protective measures. Work also needs to be directed to identifying those with whom normative comparisons are made and the relative influence of different referents.
Practical implications
The findings argue for a move away from reliance on the passive presentation of information to people and communities that dominates risk communication. Rather, strategies for encouraging and sustaining positive discourse about hazards and their mitigation within a community should be prioritized in future risk communication work.
Originality/value
Provides new insights into the relationship between people and natural hazards and provides empirical support for the inclusion of attitudes and social norms in risk communication work. It provides additional support for accommodating the social and cultural context in the development and delivery of risk communication strategies.
