The communities face persistent challenges, including livelihood failure, poverty, high exposure and sensitivity, and lower adaptive capacity, yet little attention has been paid to comprehending their multifaceted livelihood vulnerabilities amid climate-induced disasters. This study bridges that gap by employing several techniques to address the challenge. It adopts a mixed-method analysis and investigates the Livelihood Assessment Index (LAI), Livelihood Vulnerability Index (LVI), and Climate Vulnerability Index (CVI) to assess the livelihood vulnerability of fishing communities residing in the new and old fishery ghats (riverside locations where fishing-related activities take place) in Chattogram district in southern Bangladesh. Findings reveal that the fishing communities experience higher exposure levels and moderate vulnerability in the face of escalating climate-induced disasters. The overall LAI indicates a relatively low level of livelihood satisfaction, suggesting potential challenges or deficiencies in aspects contributing to well-being. Despite socioeconomic and demographic similarities, as LVI values present, the exposure varies between the two study locations. Both locations are characterized by moderate sensitivity, while the new fishery ghat showed slightly higher adaptive capacity, contributing to greater resilience. The CVI values indicated higher vulnerability for the new fishery ghat fishing community, suggesting increased challenges related to climate-induced threats, and the old ghat community exhibited lower vulnerability, showcasing better resilience to disasters. Factors influencing livelihood vulnerability include limited access to education and healthcare in the new fishery ghat, while the old fishery ghat benefits from better provisions, communication, and social networks. The study advocates for context-specific decision-making and targeted interventions to support vulnerable fishing communities in coastal zones globally, emphasizing the need for improved social safety nets and alternative livelihood options. Addressing these occupational vulnerabilities is crucial for long-term development in climate-risk countries like Bangladesh.</div></div>","PeriodicalId":52341,"journal":{"name":"Progress in Disaster Science","volume":"24 ","pages":"Article 100382"},"PeriodicalIF":2.6,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142578221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the context of hazardous meteorological conditions, risk communication aspiring to encourage desired protective action decision-making from the public must consider these cognitive factors. For messages encouraging protective action, the audience must receive, understand, and internalize the message before acting. Spatial processing of information may impact a person's understanding and is a precursor to taking protective action. This study proposes a critical assessment of relevant cognitive behavior literature into a synthesis with implications for hazardous weather risk communication. Socioeconomic and other demographic factors (e.g., education, social status, income) have a strong influence on risk perception and resultant behavior. For example, lower economic status individuals may perceive a lower risk when confronted with a particular situation relative to those with higher economic status and be more apt to take higher risks if the potential loss of income was perceived as a worse outcome for themselves individually. Additionally, previous research found age and other demographic-related differences (e.g., gender) in how people remember information when presented in a map-like versus first-person/ground-level perspective. Younger adults use a coordinate processing strategy while older adults use a categorical processing strategy. Both groups had a similar level of accuracy in recall; however, older adults were less accurate when recalling information from first-person perspective layouts. This suggests individual differences in how information presented on maps is processed (e.g., forecasts, hazardous weather alerts) compared to personal perception of the weather when it is experienced. Perceptual differences could result in increased public exposure to dangerous conditions otherwise believed, or perceived, to be safe.</div></div>","PeriodicalId":52341,"journal":{"name":"Progress in Disaster Science","volume":"24 ","pages":"Article 100380"},"PeriodicalIF":2.6,"publicationDate":"2024-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142441670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the devastation, the government and humanitarian agencies undertook a variety of shelter recovery programs. However, there are reports that a large number of people were not supported for their shelter recovery, so questions arise regarding to what extent they managed to recover. The conceptual framework of this paper is framed by two related discourses – the vulnerability paradigm and a pro-poor policy agenda – relevant in the Global South context of the Philippines. The reason for focusing on shelter is because that is the sector which often experiences maximum impact in disasters, as was the case in Yolanda. Shelter recovery is a protracted process, and agencies usually engage over the short term, which is why this paper laid the foundation for future empirical investigations on the conditions on the ground now. There are many challenges in the recovery process, complicated by the government's restrictions on rebuilding near the coast, where nonetheless people built informal settlements to pursue their coastal livelihoods, and are hence vulnerable to future typhoons. Drawbacks of the shelter interventions are explored in relation to poverty, participation, self-recovery, land tenure, urban and rural differences, post-Yolanda cost escalation and links to Water, Sanitation and Hygiene (WASH). It is recommended that people should be supported to build disaster-resilient and durable shelter, drawing on their social capital.</div></div>","PeriodicalId":52341,"journal":{"name":"Progress in Disaster Science","volume":"24 ","pages":"Article 100378"},"PeriodicalIF":2.6,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142433335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we assess whether mitigation measures used to manage a disaster can also have negative impacts that disproportionately burden vulnerable sub-sets of a population. We use data from a survey of Singaporean citizens and permanent residents during the lockdown period between April and July 2020 to evaluate the social and economic impacts of Singapore's COVID-19 mitigation measures. Our results show that over 60 % of the population experienced negative impacts on their social lives and 40 % on household economics. Bayesian Hierarchical Logistic Regress reveals that the negative economic impacts of the mitigation measures were partly influenced by socio-economic and demographic factors that align with underlying societal vulnerabilities.

Therefore, it is important to materialize such potential using appropriate techniques through utilizing the natural power of the flow-sediment regime, especially in the tidal rivers. Towards the development of nature-based solution (NbS), the principles of bandal-like structure, a V shape permeable groin-like structure was designed for the bidirectional tidal environments and applied in a tidal reach of the river Pyra. It is found that the structure has a high potential to enhance sedimentation along the bank line, while having difficulty in retaining the trapped sediment within the complex flow-sediment regime of tidal environment. To overcome such a problem, different types of vegetation are integrated with this structure to test the potentiality of vegetation in accelerating the sedimentation and its retention in the study site. Through systematic monitoring of the growth of vegetation and their performance it was found that only the site-specific native vegetation (Hogla and Shoila) grew well, while other planted species did not survive. Moreover, continuous maintenance and proper nursing of plants were required against the hydrodynamic stresses and human and animal interventions till their maturity. Several parameters related to vegetation-flow-sediment data were collected by using ADCP, Eco sounder, total station, and soil sampling to clarify the changes in flow and soil parameters due to vegetation. The results reveal that the cohesiveness of the soil increases by about 72–110 % and flow velocity reduces by 35–40 % in the area with densely grown vegetation having flow depth &lt; 5 m. While velocity reduction is relatively low (10–15 %) in the area with sparsely grown vegetation and having flow depth &gt; 5 m.

Santa Cruz de Tenerife is one of the many cities worldwide threatened by this phenomenon. Its typically Mediterranean rainfall pattern, characterized by extreme precipitation events in short periods of time, together with its orography of steep ravines, short length and width, as well as its disorderly growth, make it a space prone to the occurrence of flash floods. In addition, the increase in torrential rainfall as a consequence of climate change and the tendency towards greater irregularity in precipitation is considerably intensifying the problem. This paper studies the characteristics of these episodes and the black spots inventoried in its General Management Plan (PGO for its initials in Spanish). On the other hand, flood modeling is carried out based on the rainfall characterization, whose maximum flows, in total, range between 500 and 1600 m³/s. Finally, a methodology that allows integrating both analyses to obtain a detailed hazard map is proposed as an alternative to the more traditional flood hazard analyses. A design storm of 288 mm is applied and the data is validated against the largest rainfall event on record, March 31, 2002. It has been shown that in an urban drainage network, the main watercourses and those that have disappeared due to urbanization represent areas susceptible to flooding and are the sectors that should be emphasized during the implementation of risk reduction measures. Finally, emphasis is placed on the need to integrate future climate projections of precipitation to better define the maximum flood flows.</p></div>","PeriodicalId":52341,"journal":{"name":"Progress in Disaster Science","volume":"24 ","pages":"Article 100372"},"PeriodicalIF":2.6,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590061724000620/pdfft?md5=48fa41806ef4b2395439f7d13a761d28&pid=1-s2.0-S2590061724000620-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142274876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
