Implementing a combination of green and grey infrastructures has emerged as a highly effective approach for mitigating urban flooding. Given the complex dynamics of urban runoff, it is crucial to evaluate various strategies involving these infrastructures to efficiently manage flood risk. To address these challenges, this study proposes a conceptual framework aimed at implementing green-grey infrastructure strategies, with a specific focus on mitigating flood volume from source area to hazard area. By employing a tracer-aided urban flood model, this framework can effectively decrease flood volume within drainage systems, thereby reducing potential losses from urban flooding. Furthermore, the cost-benefit of green-grey infrastructure in flood management was thoroughly assessed, providing a robust quantitative foundation for flood mitigation and cost management. The framework was successfully applied to the Longkungou drainage system in Haikou City. The results showed a reduction in flood volume by 339836 m³, with a reduction rate of 36.1%, which achieved the expected flood mitigation target. Cost-benefit analysis further revealed that relying solely on either grey or green infrastructure is inadequate for optimal stormwater management. While grey infrastructure demonstrates high efficiency in addressing major flood events, green infrastructure offers significant environmental benefits and is particularly effective for smaller rainfall events. The integration of both green and grey infrastructures has been proved to be the most beneficial overall for disaster mitigation. In summary, this study highlights the importance of combining green and grey infrastructure strategies to achieve comprehensive and effective urban flood management.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"121 ","pages":"Article 105432"},"PeriodicalIF":4.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843837","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}

The objective of this work was to examine the spatial dependencies between socioeconomic vulnerability and flood impacts in Southern Malawi, merging geospatial methods with econometric modeling. The analysis revealed significant spatial dependencies and spillover effects from data in the Unified Beneficiary Register, Malawi Census, and Rapid Damage Assessments from the 2020 and 2022 floods. Moran's I analysis emphasized the need to account for those spatial spillover effects. The spatial econometric framework, represented by a spatial lag variable in the Spatial Generalized Linear Model, captured these dependencies effectively. Expected associations emerged between flood impacts and socioeconomic indicators such as wealth, education, and household savings, suggesting that economically secure households are less vulnerable. However, unexpected correlations also appeared: food security was positively associated with flood impact, while disability occurrence showed a negative association. These findings challenge resilience assumptions and raise concerns about data accuracy and aftershock dynamics. Insights highlight the need for DRM strategies that incorporate exposure and socioeconomic indicators, along with improved data collection to ensure vulnerable groups are adequately represented. Despite challenges from data scarcity and spatial granularity, this study demonstrates the potential of Spatial Econometric Models to identify spatially interconnected vulnerabilities. The approach can be transferred to other contexts, but further research is needed to refine spatial resolutions and ensure actionable vulnerability characterizations. Integrating spatial dependencies into risk assessments highlights the need for spatially explicit policy interventions to strengthen resilience and advance risk-layering strategies.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"121 ","pages":"Article 105433"},"PeriodicalIF":4.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843929","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}

Pressure from rapid population growth in many large cities has led to massive urban sprawl, resulting in intensive land use in the suburbs. An increase in urban capacity has not accompanied this—both in terms of institutions and drainage infrastructure—which can increase vulnerability to flooding. Environmental issues and other socio-economic constraints require sustainable and integrated flood management efforts relying on Blue-Green Infrastructure (BGI). This study seeks to minimize the risk of urban flooding by assessing the population's accessibility to blue-green spaces and formulating several socio-physical parameters to identify priority areas for developing various BGI components. With a case study of Bekasi City, the research reveals how spatial patterns of the relationship between flood hazard, blue-green-gray space, and population density help determine appropriate BGI interventions. The limited accessibility to blue-green space and weak infrastructure integration must be managed with adequate planning to suit local characteristics and solid policy enforcement through integration into existing spatial planning. This also relates to the importance of regional connectivity and collaboration of cities in the Jakarta Metropolitan Area to drive BGI interventions across scales. The study researched in Bekasi City can provide a good basis for insights relevant to developing further research and broader policy enforcement for flood management in metropolitan areas.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"121 ","pages":"Article 105425"},"PeriodicalIF":4.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843753","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}

The concept of equitable recovery is considered in the framework, and the effects of economic policies on enhancing community resilience are investigated. First, computer vision techniques using DL and remote sensing post-tornado images are employed for rapid, immediate, and accurate damage assessment of buildings. The post-disaster building damage assessment results are then used to determine the Enhanced Fujita (EF) tornado map. Subsequently, the damage states (DSs) of buildings and the EF map serve as inputs for the initial conditions of the post-disaster recovery analysis. The long-term recovery is simulated using ABM, which utilizes various loss, recovery, and socioeconomic predictive models. The Gini index estimates the inequality in the recovery processes among different socioeconomic groups, leading to a novel equitable resilience measure. Hence, the framework enables the incorporation of various hazard mitigation policies and facilitates decision-making for efficient restoration and equitable community resilience. The framework is applied to the Joplin testbed, subjected to the 2011 Joplin tornado, to demonstrate its efficiency and suitability for immediate post-disaster assessment and policymaking to enhance community resilience. The results indicate that the proposed framework ensures a more comprehensive and practical resilience analysis than the ABM approach, which relies solely on predictive hazard and fragility analysis.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"121 ","pages":"Article 105427"},"PeriodicalIF":4.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843756","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}
