However, no single study comprehensively assesses the climate-resilience of retrofitting. The purpose of this study is to address this gap via a systematic literature review. Design/methodology/approach Quality journal studies were selected using the PRISMA method and analysed manually and using scientometrics. Three dimensions of climate-resilience, such as robustness, withstanding and recovery, were used to evaluate the contribution of retrofit measures for achieving climate-resilient houses across four climate zones: tropical, arid, temperate and cold. Findings Most passive measures can enhance the robustness of residential buildings but cannot verify for withstanding against immediate shocks and timely recovery. However, some passive measures, such as night-time ventilation, show excellent performance over all four climate zones. Active measures such as heating, ventilation and air conditioning and mechanical ventilation with heat recovery, can ensure climate-resilience in all three dimensions in the short-term but contribute to greenhouse gas emissions, further exacerbating the long-term climate. Integrating renewable energy sources can defeat this issue. Thus, all three retrofit strategies should appropriately be adopted together to achieve climate-resilient houses. Research limitations/implications Since the research is limited to secondary data, retrofit measures recommended in this research should be further investigated before application. Originality/value This review contributes to the knowledge domain of retrofitting by assessing the contribution of different retrofit measures to climate-resilience.","PeriodicalId":45983,"journal":{"name":"International Journal of Disaster Resilience in the Built Environment","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139254077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aims to identify the job attributes of key Sri Lankan construction professionals in addressing challenges associated with climate change. Design/methodology/approach The study adopted a mixed research approach. A literature review and preliminary semi-structured interviews were used to appraise the job roles of architects, engineers and quantity surveyors in addressing challenges associated with climate change. The data collected through the qualitative approach were used in an online questionnaire survey, and the findings were analysed using the relative index method. Findings The findings highlight that regardless of the knowledge of the professional category on green rating tools, carbon footprint, adaptation of renewable energies for the reduction of energy consumption, building information modelling-related applications and waste management concepts/practices are the foremost job attributes required for the key Sri Lankan construction professionals in addressing challenges associated with climate change. Research limitations/implications The results from this study provide a handful of guidance to construction industry professionals, national and international professional institutions, non-governmental organisations and other relevant authorities to address climate change within the built environment by identifying ways for improving the relevant key job attributes of construction industry professionals.

The study aims to assess how an ST approach to pedagogy compared against a conventional approach in terms of contribution to the participants’ global climate change content knowledge, holistic thinking and depth and accuracy of knowledge and reasoning. Design/methodology/approach The study implemented e-learning modules using an ST approach versus a conventional approach in teaching climate science to junior high school teachers. The paper presents quantitative data obtained from pre and posttests results of the 20 teacher-participants and qualitative data obtained during the focus-group discussion (FGD) after the implementation of the study. Findings The results from the statistical analysis indicated that the ST group obtained a significant increase in their assessment scores compared to the non-ST group, according to predetermined criteria. Content knowledge, depth and accuracy of knowledge and reasoning increased the most. The participants mentioned during the FGD that the module helped deepen their understanding of climate change. Research limitations/implications The study was limited to 20 teacher-participants, but it has relevance for public school teachers in the country given that participants had raised concerns regarding the lack of training in their schools for teaching climate science. They admitted that they lacked critical information to include in climate change topics in their classes. Originality/value This paper shows how the ST approach can be used to teach climate change to junior high students. The e-learning module can provide teachers with better understanding, knowledge and reasoning to teach climate change to high school students more effectively.","PeriodicalId":45983,"journal":{"name":"International Journal of Disaster Resilience in the Built Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134992733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Understanding householders’ perceptions of threats following the 2019/2020 Black Summer bushfires in Australia","authors":"Olufisayo Adedokun, Temitope Egbelakin","doi":"10.1108/ijdrbe-11-2022-0114","DOIUrl":"https://doi.org/10.1108/ijdrbe-11-2022-0114","url":null,"abstract":"Purpose Of all the deaths associated with disasters, bushfires account for 40% of these fatalities. The resulting fatalities are consequent upon householders’ decision-making, leading to late or non-evacuation from at-risk communities. However, while decision-making is a function of risk perception, this paper aims to investigate householders’ perceptions of bushfire risks following the catastrophic Black Summer bushfires of 2019/2020. Design/methodology/approach An inductive research approach was adopted. Thirty semi-structured interviews were conducted to elicit qualitative data from southeastern NSW, Australia householders. The data were collected via face-to-face and online Zoom. Each interview was recorded, transcribed using Otter.AI and thematically analyzed with NVivo 12 Pro (Braun and Clarke, 2006, 2019). In addition, inter-rater reliability was done by engaging an independent researcher to code the de-identified data independently. The codes were cross-checked for reliability and adjusted where necessary. Findings It was found that bushfire risk perceptions were high among the householders in bushfire at-risk communities following the 2019/2020 Black Summer bushfires. High levels of perceptions were recorded among the participants regarding the likelihood of bushfire occurrence, concern for bushfires, severity of bushfires and vulnerability to bushfire threats. Research limitations/implications The study’s results do not reflect all householders in the southeastern part of NSW. It was limited to 30 householders who indicated their intentions to participate and are living in the study area. Therefore, future studies should be undertaken with more participants from broader geographical areas, including emergency responders like firefighters, recovery officers and non-government organizations in charge of recovery operations. This study will add to the prioritization of risk perceptions. Practical implications All else being equal, elevated bushfire risk perceptions among participants can potentially decrease the fatalities linked with bushfires and their subsequent ripple effects. This holds particularly true when residents opt for early self-evacuation from at-risk communities. Social implications The paper contributes to developing a better understanding of the bushfire risk perceptions underlying the evacuation decision-making of the residents in bushfire at-risk communities in south-eastern NSW of Australia. Originality/value The paper contributes to the existing knowledge on bushfire risks by providing insights into residents’ perceptions after the catastrophic 2019/2020 Black Summer bushfires. As a qualitative study, it describes bushfire risk perceptions on four themes: likelihood, concern, severity and vulnerability, which is uncommon in many bushfire studies.","PeriodicalId":45983,"journal":{"name":"International Journal of Disaster Resilience in the Built Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135567431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Up to now, no comprehensive study has been done regarding adolescents’ roles and experiences in all stages of disaster management, and discussions existing in the domain of adolescents’ engagement in disaster risk management are usually restricted to children’s participation. Thus, this study aims to extract the effective components and factors in disaster education to improve adolescents’ resilience to disasters. Design/methodology/approach This systematic review was done through English databases and three Persian databases between August 18, 2001, and August 31, 2021. The articles were searched based on the PRISMA checklist using four key dimensions of “resilience,” “disasters,” “adolescents” and “education.” Finally, the effective components and factors in disaster education for improving adolescents’ resilience during disasters were extracted. Findings Totally, 29,856 articles were extracted through the systematic review. After studying the titles, abstracts and contents of the extracted articles, 17 were selected for the final analysis. Among these articles, 3, 12 and 2 had qualitative, quantitative and mixed research designs, respectively. The extracted components were categorized into five major categories including education, community, adolescents, resilience and governing policies and approaches. Research limitations/implications Unfortunately, due to sanctions, Shiraz University of Medical Sciences did not have access to the Embase database, and consequently, this database could not be used. Originality/value The results of this systematic review presented an overall view of the effective components of adolescents’ disaster resilience education.

Therefore, this study assessed if Australian climate, disaster and emergency management policies provide effective mechanisms for governing displacement crises and areas where current approaches could be improved. Design/methodology/approach This study assessed 18 national and state-level disaster, emergency and climate change management frameworks to determine if best practice displacement governance themes were reflected in policy documents. Deductive thematic analysis was undertaken using Braun and Clarke’s six-phase method. Findings Issues of displacement are reflected in policies analysed in this study. However, current policy frameworks need to be equipped to comprehensively address the housing requirements of displaced people or provide long-term initiatives. Approaches are focused on crisis management rather than pre-emptively planning for displacement response and recovery. Therefore, Australia has not exercised national responsibility for displaced people appropriately. Research limitations/implications Disaster displacement is an under-researched area of Australian scholarship and disaster management policy and practice. Therefore, this paper has practical implications in so far as it draws attention to the issue of displacement in Australia. A limitation of this paper is that it only analysed policy frameworks specific to disasters. While broader engagement was outside the scope of this study, this limitation provides opportunities for further research from disciplinary perspectives of public housing and homelessness to examine displacement policy challenges in these fields. Furthermore, this study is limited to a theoretical inquiry into this topic through a desktop review of policy documents. While this is a necessary first step, empirical studies are required to determine accurate displacement rates, drivers and people’s experience of being displaced. Practical implications This research aims to inform policy by presenting recommendations for policy interventions for disaster displacement governance. Therefore, this research has practical implications as policy and disaster risk reduction (DRR) professionals can draw from the findings of this research when planning and initiating disaster response for displaced persons. Social implications This research draws attention to an area of disaster management practice and policy that has not been adequately accounted for. Highlighting gaps in current policy can assist in developing targeted strategies and solutions for internally displaced people, which protect their rights and meet their needs. Originality/value Displacement is a growing climate change issue. This research aims to help address this problem by drawing attention to areas where Australian disaster management approaches fail to account for displaced populations.

This study aims to find certain indicators for planning and designing future courses of inclusive online education in the domain of disaster risk reduction (DRR). Design/methodology/approach The study reviews and analyses online teaching and learning experiences of DRR courses. It uses online surveys and interviews to derive the perspectives of selected students and educators in universities in Asia and the Pacific region. Findings Active engagement is considered to be achieved when students are active in chat boxes, through presentations, through assignments and when the video cameras of students are turned on. On the contrary, students perceive active engagement differently because they face emotional disturbances and health issues due to prolonged screen/digital device use, have inadequate information and communications technology infrastructure or have digital literacy deficiencies among others. The study finds that online courses have many sets of strengths, weaknesses, opportunities and threats, when they are balanced, they can improve DRR courses in the future. Research limitations/implications The study is based on the outcome of interviews with 10 experienced educators in DRR courses as well as students from different schools taking courses in DRR education. However, the students are not necessarily taking the courses of the educators interviewed due to the inability of some educators to avail themselves and the challenge of contacting the students. This notwithstanding, the results of this study give a general overview of the situation to be considered in the planning and design of online and distance education. Social implications The results do not reflect the reaction of students and tutors of the same course. Future studies of collecting and analyzing the responses from the students and the educators with the same course could provide tailored solutions.

The authors accomplished this through proportional comparisons and negative binomial regression models. Findings While traffic levels were 30%–50% below normal during the COVID-19 lockdowns, all traffic fatalities decreased by 18.3%, pedestrian fatalities decreased by 19.0% and bicyclist fatalities increased by 3.6%. Fatal COVID-19 crashes were more likely single-vehicle crashes involving fixed objects or rollovers.
