However, common hydrodynamic models remain too computationally expensive for real-time flood forecasting, while current surrogate models have so far not been able to simulate flood arrival times for dike breaches. In this study, we develop a fast conceptual model for this purpose, based on a digital elevation model and a linear regression equation for flood propagation velocity. The linear regression was derived from a sensitivity analysis of hydrodynamic simulations of idealized dike breaches, where we identify the most important hinterland characteristics that determine the flood propagation velocity. The sensitivity analysis shows that hinterland slope in the propagation direction is most important for the propagation velocity, while breach discharge is most important close to the breach. The fast conceptual model computes flood arrival times by applying this linear regression along the local drainage direction (steepest slope) path leading away from the breach, taking peak breach discharge as input. The model achieves accurate results for two case study dike breaches along the Rhine river near the Dutch–German border, especially in the first 48 h after the breach. The mean absolute arrival time error is about 2 to 4 h, and computation time is less than a second. We conclude that this model can serve as a fast disaster preparation and response tool to support flood disaster management, for determining evacuation strategies and uncertainty analysis of possible breach discharge scenarios.</div></div>","PeriodicalId":52341,"journal":{"name":"Progress in Disaster Science","volume":"30 ","pages":"Article 100565"},"PeriodicalIF":3.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147657201","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}

Happiness differs significantly by income, education, and disability severity. Perceived disaster vulnerability is negatively associated with happiness and partially mediates the relationships between education and disability severity and happiness. In contrast, environmental dimensions—such as formal health and welfare services and physical convenience—show direct associations with happiness but do not operate through perceived vulnerability.

To improve risk management efficiency, and fortify food security infrastructure, we combine a bundle of approaches to research China's agricultural insurance, including statistical analyses, questionnaire survey and direct interviews. Tracing the policy mechanisms introduced since 1982, we delineate two distinct stages in China's agricultural insurance evolution. The present subsidy-based system has substantially reduced aggregate disaster exposure over the past eighteen years. Yet beneath these aggregate gains lie widespread lack of knowledge and persistent under-adoption, both symptoms of an enduring capital shortfall in the insurance pool. Drawing on risk- layering principles, we propose the creation of Agricultural Insurance Investment Funds that bundle existing subsidy-based policies, thereby improving the efficiency of China's agricultural insurance system.</div></div>","PeriodicalId":52341,"journal":{"name":"Progress in Disaster Science","volume":"30 ","pages":"Article 100567"},"PeriodicalIF":3.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147797604","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 event, precipitated by the convergence of Tropical Storm PODUL and Tropical Depression KAJIKI, led to substantial human and economic losses. The methodology employs: (i) flood mapping with an enhanced Kittler-Illingworth thresholding technique incorporating terrain correction to mitigate slope-dependent backscatter variations; (ii) crop classification using a novel Dual Polarization SAR Vegetation Index (DpSVI); and (iii) robust validation against field data and optical imagery. The analysis encompassed flood extent determination, flooded agricultural area quantification, crop type distribution (Sugarcane, Cassava, Maize, and Rubber), assessment of crop type area affected by flooding, and evaluation of farmers’ exposure to flooding from September 1st to September 30th, 2019. Results indicate that 3890.4 km<sup>2</sup> (8.4% of the study area) was flooded, with Yasothon experiencing the highest agricultural impact (19.6% of its agricultural area).

The onset and persistence of demographic changes following disaster were identified based on deviations from pre-disaster population trends using the logarithm of population change. Among Asakura's 19 communities, three that were already experiencing population decline exhibited impacts from the disaster. In these areas, accelerated decline persisted for 1–5 years, with 1.9 to 3.4 times greater than the pre-disaster levels. Analysis using a penalized logistic model revealed that the magnitude of physical damage (fatalities, housing damage, and road damage), rather than hazard magnitude (area coverage of landslides, floods, and woody debris deposits), was related to whether demographic changes occurred. In particular, the housing damage rate emerged as the strongest explanatory factor. Furthermore, the duration of population decline was positively correlated with the extent of physical damage.

This study looks at the link between policy frameworks for national climate and disaster policies and community based adaptation practice, and in particular the disconnect between gender commitments in the policy framework and their implementation at the local level. The study outlines a governance pathway framework, which describes how policy commitments travel through stages of institutional translation and program implementation before influencing community outcomes. The research assesses governance mechanisms, institutional capacity and measurement limitations which limit verification of gender responsive resilience. Key limitations include lack of gender disaggregated indicators, weak financing mandates, little monitoring of e.g. gender based violence outcomes, and a lack of inclusion of adolescents and persons with disabilities. Findings show that policies such as BCCSAP, NAPA, ccGAP, NPDM, and BCCTF make reference to gender equality but have no mechanisms for enforcement, coordination arrangements, and gender responsive budgeting provisions. Institutional fragmentation as well as monitoring systems that focus on indicators of participation undermine a policy translation into operational programs. Community based adaptation initiatives document participation but few improve decision authority and access to services for women and marginalized groups.
