Current research on optimizing the deployment of healthcare emergency facilities under flooding scenarios remains limited, particularly in terms of considering both the population coverage and spatial coverage. Based on the simulation of urban flooding, this study proposes a dual-constrained emergency facility location optimization model that balances both the newly added service population and newly service scope, and its effectiveness is validated in the Maozhou River Basin in Shenzhen. The results indicate that urban flooding in the study area is caused by insufficient drainage capacity and low-lying topography, with the former being the dominant contributing factor. Additionally, rainfall events exceeding a 78 mm/h(10-year threshold) alter the shortest access routes to healthcare emergency services for over 50 % of the population.Compared with the decrease in traffic speed, impassable roads due to flooding exert a greater effect on healthcare emergency services. Lastly, optimization outcomes under three flooding scenarios demonstrate the applicability of our model, accurately determining the location of high priority healthcare emergency facilities. Non-inundated populations now achieve assured 15-min healthcare emergency response. This study provides a scientific foundation for urban emergency departments to plan resource allocation, reducing risks from healthcare delays in non-inundated areas.</div></div>","PeriodicalId":52341,"journal":{"name":"Progress in Disaster Science","volume":"28 ","pages":"Article 100473"},"PeriodicalIF":3.8,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219538","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}

This study evaluates how community-driven tourism initiatives at Caota Geopark, Taiwan, contribute to climate resilience by enabling public education and engagement with nature conservation. Using a social-ecological systems lens, this study explores how the interplay between community participation and coastal ecosystem processes supports Nature-based Solutions (NbS) in addressing locally identified climate risks. This is achieved through a combination of contextual analysis and qualitative methods, including focus group discussions and semi-structured interviews with local stakeholders. Thematic analysis revealed that environmental education and awareness-building have strengthened local commitment to environmental stewardship. Moreover, enhancing the buffering capacity of the coastal dunes and maintaining associated ecosystem services were identified as key strategies for mitigating local hazards. However, ongoing challenges such as waste accumulation, inadequate infrastructure, and human disturbances, undermine ecosystem functions and visitor experiences, revealing critical vulnerabilities within the social-ecological system. Additionally, the study found a gap in inclusive, bottom-up governance structures that could help integrate community needs into geopark planning. Building on these insights, the study proposes a framework for sustainable tourism management and locally grounded climate adaptation strategies that stimulate active community participation.

The approach categorizes dam failure into subcases based on flood severity and the distance from the dam. Two empirical equations that serve as the calculation method for LOL formulated through multivariate regression analysis are derived using thirty-two dam failure subcases in North America. The datasets were split into train and test sets, yielding R<sup>2</sup> values of 0.9949 for low severity cases and 0.9955 for medium-high severity cases on the test sets. Graham's model was selected as a comparison benchmark due to its straightforward application, established use in LOL estimation, and minimal data requirements.

This study investigates these effects through landslides–debris flows coupled numerical analysis, employing three soil depth configurations: the slope-based S model, the elevation-based Z model, and the U model, which assumes uniform soil depth across the study area. The 2011 Mt. Umyeon landslides in South Korea, a well-documented event with extensive field survey data, were simulated to validate the simulation results. Model performance was evaluated using the receiver operating characteristic method. Results show that increasing soil depth enlarges the scale of landslides and debris flows while delaying their onset. However, when soil depth greatly exceeds rainfall intensity and cumulative rainfall, slope failure susceptibility decreases, emphasizing the spatiotemporal control of soil thickness. In debris flow simulations, soil depth strongly influenced erosion and entrainment processes, substantially affecting downstream residential damage estimates. Furthermore, our results indicate that when soil depth data are unavailable, the slope-based S model provides more spatiotemporally stable predictions of landslide and debris flow behavior.

Focusing on a cyclone and salinity-prone coastal village in Bangladesh, the study employs a longitudinal analysis (2010 and 2025) of social and spatial aspects, revealing an evolving nature of coastal settlements, driven by both internal and external interventions that catalyze morphological change. Fieldwork reveals that the self-help approach enables local communities to incrementally reorganize their homesteads, thereby strengthening their disaster resilience. The study identifies self-organization as a dynamic process through which coastal communities recalibrate their socio-spatial patterns and settlement morphology in response to varying disaster risks and socio-economic opportunities. The dynamic interplay between community self-organization and long-term resilience offers key insights for sustainable adaptation to growing environmental challenges. This study thus contributes to the broader discourse on resilient shelter planning and adaptive strategies for coastal regions in an era of climate uncertainty.</div></div>","PeriodicalId":52341,"journal":{"name":"Progress in Disaster Science","volume":"28 ","pages":"Article 100469"},"PeriodicalIF":3.8,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145121203","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}
