The visibility of disaster politics and understanding of the policies and legal tools used by different actors during disasters is minimal, serving disaster risk reduction poorly. We examine these elements through a study of disaster responses by state and non-state actors in Malawi, drawing from 25 interviews with actors central to disaster responses, and 10 individual storytelling activities in affected communities. Results show disaster actors are not a homogenous category, and actors deploy different tools during emergencies. Disaster politics and coordination converge around the Department of Disaster Management Affairs and donors, but formal processes are ‘caught unaware’ and descend into chaos when disaster landscapes change. Meanwhile, tools and processes relied upon by stakeholders in flood disaster responses are narrow, incomplete and insufficiently account for national and local particularities and place-based vulnerabilities in disaster communities. This research shows that disaster responses should account for the nature of disaster politics, including the different policy and legal tools activated during disasters and processes relied upon and what this means for impacted communities caught in between. Actors emphasise socio-cultural and socio-political dimensions of disaster institutions to be better understood alongside fiscal-economic and legislative and regulatory elements. This paper advances an approach that accounts for <em>‘disaster scapes’</em> – as interdisciplinary, cross-sectional and holistic formulation of a whole variety of disaster outcomes beyond floodwaters to encapsulate the effects of sediment movement.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"117 ","pages":"Article 105144"},"PeriodicalIF":4.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143142980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Household defence plays a significant role in mitigating property losses but also entails notable difficulties and safety risks for residents. Despite this, very little research has closely examined what household defence experiences actually look like across different household, community, landscape and fire contexts, in order to identify ways bushfire responses can be made safer and more effective and to help identify the limits of household defence under different conditions. This research examines resident defence experiences drawn from thematic analysis of 402 post-fire household interviews conducted following a number of significant fire events that occurred in New South Wales, Australia between 2017 and 2020. A key finding is that many households are severely underprepared to defend, with lack of awareness about what constitutes adequate preparedness for defence, particularly for fire conditions beyond light ember attack. A number of misconceptions about risk, fire behaviour and defence capacity continue to shape defence readiness and notable gaps exist in many household defence plans. In particular, personal protective equipment is severely underutilised. Improved planning for water supply and distribution among households preparing to defend, as well as better contingency planning for when things go awry is also necessary. It is important that bushfire preparedness and community education initiatives work address these factors to ensure that households are better prepared to assess their risk and make decisions around their protective response in future fire events.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"117 ","pages":"Article 105150"},"PeriodicalIF":4.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, more focus needs to be placed on climate change adaptation such as ensuring effective response (e.g. flood evacuation) to safeguard that livelihoods are protected in worst-case scenarios. This study was a participatory action research (PAR), engaging Japanese school children (aged 11 and 12) in Wakayama prefecture, Japan, in a series of interactive workshops focused on discussing flood evacuation and facilitating exposure to Agent-Based Modelling (ABM), which has potential to facilitate disaster preparedness learning in this context. As current flood evacuation is predominantly informed by topographic and demographic data, there is an exclusion of key impacting variables like social data (e.g. evacuation start times, etc.), and this research sought to include these. Through homework exercises issued to school children, social datasets were collected and included within a computational model of flood evacuation, creating an enhanced ABM-approach. Results illustrated that when comparing the enhanced model to an initial model that did not include social datasets, the addition offers more detailed and accurate insights into flood evacuation behaviour. Also, feedback from the school children that followed the workshops further established that engagement through the use of ABM raised awareness and interest towards their flood evacuation, which is essential to successful DRR. These findings suggest that consideration of variables beyond topography and demographics needs to be taken into account within future ABM in this context, and taking a participatory approach in ABM can have benefits to engage and educate samples affected by disasters. The study will need to be expanded to include the same approach within schools beyond Japan, and include other stakeholders where flooding is an increasing issue, and enlarge social variables used to ensure greater robustness in the modelling.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"117 ","pages":"Article 105180"},"PeriodicalIF":4.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143143084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Online and face-to-face surveys collected data from 143 respondents, including residents, workers, and visitors. The results reveal significant differences in fire preparedness and awareness, with only 27 % of respondents having experienced directly a fire and 63 % participating in fire drills. The analysis shows that residents and workers are more familiar with emergency resources than leisure visitors and that previous fire experiences and drills significantly improve fire response preparedness. Demographic variables such as age, gender, and nationality do not significantly impact emergency response decisions, except for knowledge of emergency contacts, where foreign nationals are less aware than locals. The resilience analysis indicates that, although many residents have shelter and alternative work options, financial constraints reduce their ability to manage reconstruction independently. It highlights the need for targeted educational programs, improved communication strategies between authorities and the public, and increased investment in financial support mechanisms to strengthen community resilience. The study also underscores the importance of future research to explore the influence of family structures and cultural dynamics on fire resilience, evacuation drills' effectiveness, and community support networks' role in post-disaster recovery. Extending this study to other areas with similar characteristics or integrating it with vulnerability analyses could further improve the resilience level to urban fires. These findings provide a comprehensive framework for improving urban fire preparedness and response in historic centers, contributing to safer and more resilient communities.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"117 ","pages":"Article 105131"},"PeriodicalIF":4.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143142958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Guided by Protection Motivation Theory, this work assessed the relationships between risk communication and storm preparedness cognition to evaluate the usefulness and usability of an original storm preparedness app. Findings suggested that risk communication was a positive predictor of storm risk susceptibility and severity as well as preparedness self-efficacy and response efficacy. Results also indicated that while risk susceptibility and preparedness self-efficacy respectively and positively predicted risk severity and response efficacy, only risk severity and response efficacy were significant predictors of perceived app usefulness. Perceived app usefulness, in turn, positively predicted app usefulness. This study thus ascertained the role of risk communication in the threat and coping appraisal processes.

Previously known for its profound historical lineage, rich and diverse cultural heritage, and deep-rooted connection to its cultural identity, Antakya's reconstruction process holds a critical case not only for Turkey but also for the global discourse on urban resilience and post-disaster recovery strategies. Thus, in this study, we deep dive into an ongoing recovery process in Antakya, Turkey. The study's primary objective is to identify the key factors, constraints, opportunities, and challenges involved in reconstructing a city that can withstand future earthquakes. The data used in the study was gathered during fieldwork that was carried out in Hatay, Turkey, in June 2023. The methodology consists of total of 16 focus groups and in-depth interviews with stakeholders, including representatives of professional associations, local government agencies, and public institutions. Our results showed that re-opening educational services plays a crucial role in promoting recovery in Antakya. Furthermore, we examined the complex interplay between cultural ties to place, and urban resilience in the context of disaster recovery. We found that in Antakya, cultural identify may play a crucial role and would have a direct influence on its recovery. These findings hold significance for policymakers, urban planners, and disaster management professionals who must navigate the challenging terrain of post-disaster reconstruction while considering the cultural and emotional ties that bind residents to their cities.
