This study examines the implementation of the Sister Village Program in enhancing community-based disaster resilience in Umbulharjo Village, located in the eruption-prone zone of Merapi Volcano. Using the Disaster Resilience of Place (DROP) Model approach, this research evaluates the key elements that shape disaster resilience, including mitigation, preparedness, adaptive capacity, and inter-village collaboration. The DROP Model integrates various components that influence a region's ability to manage, respond to, and recover from disasters, covering ecological, social, economic, institutional, and community competence aspects. This approach provides a comprehensive overview of a region's resilience to disasters and offers practical guidance for improving community and regional resilience. The study highlights the importance of planned mitigation and preparedness, and active community participation in reducing disaster impacts and accelerating post-disaster recovery. The Sister Village Program which involves knowledge exchange, infrastructure improvement, and strengthening the adaptive capacity of both villages, serves as an effective disaster risk reduction model. The findings also show that collaboration between villages and institutions, along with the strengthening of social infrastructure, play a crucial role in enhancing disaster resilience. The results of this study identify that by integrating these elements, the Sister Village Program can create stronger and more sustainable long-term disaster resilience. This model aligns with the Sustainable Development Goals (SDGs), particularly those related to disaster risk reduction and community capacity building. Thus, the Sister Village Program in Umbulharjo Village demonstrates significant potential for building sustainable resilience through an inclusive and collaborative community-based approach.

本研究考察了姐妹村项目在加强Umbulharjo村社区抗灾能力方面的实施情况。Umbulharjo村位于默拉皮火山爆发易发区。本研究利用地方抗灾能力（DROP）模型方法，评估了影响抗灾能力的关键因素，包括减灾、备灾、适应能力和村庄间协作。DROP模型整合了影响一个地区管理、应对和从灾害中恢复能力的各种组成部分，涵盖生态、社会、经济、体制和社区能力等方面。这种方法全面概述了一个地区的抗灾能力，并为提高社区和区域的抗灾能力提供了实用指导。该研究强调了有计划的减灾和备灾以及社区积极参与减少灾害影响和加速灾后恢复的重要性。姊妹村项目涉及知识交流、基础设施改善和加强两个村庄的适应能力，是减少灾害风险的有效模式。调查结果还表明，村庄和机构之间的合作，以及加强社会基础设施，在增强抗灾能力方面发挥着至关重要的作用。本研究的结果表明，通过整合这些要素，姊妹村项目可以建立更强大、更可持续的长期抗灾能力。这一模式符合可持续发展目标，特别是与减少灾害风险和社区能力建设有关的目标。因此，Umbulharjo村的姊妹村项目显示出通过以社区为基础的包容性和合作性方法建设可持续韧性的巨大潜力。

The establishment of Disaster Management Support Bases (DMSBs) is becoming increasingly essential due to the rapid expansion of urban populations and the geographical positioning of Iran's cities in high-risk areas, such as earthquake-prone zones. This study aimed to identify appropriate locations for DMSBs within Region 1 of the Tehran Municipality. In this process, 26 environmental factors derived from prior research on urban disaster management were identified and categorized into five groups: urban texture, transportation, proximity (compatibility), non-proximity (incompatibility), and topography/seismicity. The factors were standardized to ensure comparability by converting different computational units into uniform values. Additionally, their relative weights were determined using the Analytical Hierarchy Process (AHP) method. Subsequent to this, Ordered Weighted Averaging (OWA) modeling was employed, applying various scenarios such as AND, OR, and Weighted Linear Combination (WLC). Through this approach, order weights allowed for controlling the trade-off between factors and varying levels of risk-taking. The next phase of the study involved evaluating DMSB site suitability using zonal land suitability (ZLS) assessments. The findings identified 17 suitable zones for DMSB construction. Following detailed field inspections, five zones were selected as optimal sites spanning different districts. An analysis of the results highlighted that, in contrast to the WLC method, OWA offers a broader range of solutions by enabling adjustments to risk levels and compensation across factors. The study concludes that the decision-making rules and methodology applied in this research are valuable and adaptable for future investigations into suitable sites for DMSBs. OWA has also significantly contributed to disaster knowledge production by providing a versatile, theoretically rich, and practically applicable framework for aggregating information, supporting decision making, and advancing research across multiple scientific and engineering disciplines.

由于城市人口的迅速增长以及伊朗城市位于地震多发地区等高风险地区的地理位置，建立灾害管理支持基地（DMSBs）变得越来越重要。本研究旨在确定德黑兰市1区内dmsb的适当地点。在此过程中，从先前的城市灾害管理研究中得出了26个环境因素，并将其分为5类：城市结构、交通、邻近性（兼容性）、非邻近性（不兼容性）和地形/地震活动性。通过将不同的计算单位转换为统一的值，将因子标准化以确保可比性。此外，采用层次分析法（AHP）确定了它们的相对权重。在此之后，采用有序加权平均（OWA）建模，应用各种场景，如AND、OR和加权线性组合（WLC）。通过这种方法，订单权重允许控制因素和不同程度的风险承担之间的权衡。研究的下一阶段涉及使用分区土地适宜性（ZLS）评估DMSB站点的适宜性。研究结果确定了17个适合建设DMSB的区域。经过详细的实地考察，选择了五个区域作为跨越不同地区的最佳地点。对结果的分析强调，与WLC方法相比，OWA通过调整风险水平和跨因素补偿，提供了更广泛的解决方案。研究结果表明，本研究采用的决策规则和方法对未来的dmsb选址具有一定的参考价值和适应性。OWA还为灾害知识生产做出了重大贡献，它提供了一个通用的、理论丰富的、实际适用的框架，用于聚合信息、支持决策和推进跨多个科学和工程学科的研究。

This study examines disaster risk perception among the Garo community in Netrokona district, Bangladesh, focusing on socioeconomic and environmental factors. Conducted in three unions- Rangchati, Lengura, and Kullagora- the research surveyed 365 households. Data were collected in October 2024 using a structured questionnaire, and statistical analysis was conducted using the ‘R' program. Ordinal logistic regression models identified key factors associated with disaster risk ratings. Findings reveal that 44 % of respondents perceive their area as a “High” disaster risk zone, associated with economic vulnerabilities (73.97 % earn less than 15,000 BDT/month) and limited access to education. Over 63 % have experienced forced displacement, and 70.68 % reported home inundation, exacerbated by environmental degradation like deforestation and groundwater depletion. Community factors, such as local governance and infrastructure, also shaped disaster risk perceptions, with residents of Lengura and Rangchati reporting lower risk perceptions. Occupation, income, and previous disaster experiences, including displacement, were strongly associated with heightened risk awareness. Households with elevated homes or strong social support networks had better preparedness, while 80.27 % lacked access to early warning systems. The study highlights the need for tailored disaster management strategies that integrate local knowledge and enhance community resilience.

本研究考察了孟加拉国Netrokona地区Garo社区对灾害风险的认知，重点关注社会经济和环境因素。这项研究在兰差地、伦古拉和库拉古拉三个地区进行，调查了365户家庭。数据收集于2024年10月，采用结构化问卷，采用“R”程序进行统计分析。有序逻辑回归模型确定了与灾害风险评级相关的关键因素。调查结果显示，44%的受访者认为他们所在的地区是“高”灾害风险区，与经济脆弱性（73.97%的人每月收入低于1.5万泰铢）和受教育机会有限有关。超过63%的人被迫流离失所，70.68%的人报告家园被淹没，森林砍伐和地下水枯竭等环境恶化加剧了这种情况。社区因素，如地方治理和基础设施，也影响了灾害风险观念，Lengura和Rangchati的居民报告的风险观念较低。职业、收入和以前的灾害经历（包括流离失所）与风险意识的提高密切相关。拥有高架房屋或强大社会支持网络的家庭准备较好，而80.27%的家庭缺乏早期预警系统。该研究强调，需要有针对性地制定灾害管理战略，整合当地知识，增强社区抵御能力。

There is increasing evidence that climate change will lead to greater and more frequent extreme weather events, thus underscoring the importance of effectively communicating risks of record storm surges in coastal communities. This article reviews why risk communication often fails to convey the nature and risk of storm surge among the public and highlights the limitations of conventional (two-dimensional) storm surge flood maps. The research explores the potential of dynamic street-level, augmented scenes to increase the tangibility of these risks and foster a greater sense of agency among the public. The study focused on Sunset Park, a coastal community in southwest Brooklyn that is vulnerable to storm surges and flooding. Two different representations of flooding corresponding to a category three hurricane scenario were prepared: (1) a conventional two-dimensional flood map (“2D” control group) and (2) a, dynamic, street view simulation (“3D” test group). The street view simulations were found to be (1) more effective in conveying the magnitude of flooding and evacuation challenges, (2) easier to use for judging flood water depth (even without a flood depth legend), (3) capable of generating stronger emotional responses, and (4) perceived as more authoritative.in nature.

Rural distributed storage systems are green infrastructure that decentrally store flood water across the landscape to reduce downstream flood peaks. Despite growing understanding of their flow reduction potential, the evidence base for their economic risk reduction is thin. This study quantifies the economic benefits of distributed storage constructed in an agricultural region of Iowa. The system was financed through the US National Disaster Resilience Competition, and adopted a voluntary conservation approach that provided cost-share assistance to landowners. Our sequential analysis employed high-resolution modeling of watershed hydrology, flood exposure of buildings and crops, and economic risk. Construction and maintenance costs were included in scenario analyses of constructed storage structures and maximum potential structure buildout. The maximum benefit-cost ratio was 0.34, falling below the traditional threshold of 1.0 used for project selection in hazard mitigation. The results are highly sensitive to the geospatial accuracy of exposed buildings, and the flood-reduction benefits diminished at larger spatial scales. To improve risk reduction benefits, project siting should consider the location along the stream network and proximity to high-value properties. The inclusion of nonmonetary co-benefits such as improved water quality, landowner amenities, ecosystem services, and community collaboration would also strengthen the case for resilience cost-effectiveness.

农村分布式存储系统是一种绿色基础设施，它分散地将洪水存储在整个景观中，以减少下游洪水峰值。尽管人们对它们减少流量的潜力了解越来越多，但它们降低经济风险的证据基础却很薄弱。本研究量化了在爱荷华州农业地区建设分布式存储的经济效益。该系统由美国国家抗灾竞赛资助，并采用自愿保护方法，为土地所有者提供成本分担援助。我们的序列分析采用了高分辨率的流域水文模型、建筑物和农作物的洪水暴露以及经济风险。在对已建成的存储结构和最大可能的结构扩建进行情景分析时，包括了建造和维护成本。最大效益成本比为0.34，低于用于减灾项目选择的传统阈值1.0。研究结果对暴露建筑物的地理空间精度高度敏感，且在更大的空间尺度上，减洪效益降低。为了提高降低风险的效益，项目选址应考虑沿水系网络和靠近高价值物业的位置。包括非货币的共同利益，如改善水质、土地所有者便利设施、生态系统服务和社区合作，也将加强弹性成本效益的案例。

This paper seeks to address the methodological deficiency in assessing the adoption of climate change adaptation practices within fishing and farming communities in a coastal upazila of Khulna district, Bangladesh. The derivation of an adaptation index is elucidated, considering the weight of adaptation practices based on their effectiveness, feasibility, and sustainability, as well as the number of practices adopted by households in farming and fishing communities. From the data collected through the Focus Group Discussion, household questionnaire survey, and workshop, the average household adaptation index value was established. A total of 123 household surveys were conducted within the fishing community, alongside 125 household surveys from the farming community. Additionally, 8 focus group discussions and 8 workshops took place in Dacope upazila. Sutarkhali shows the highest adaptation index among fishing communities, while Bajua leads among farming communities. Multiple regression analysis indicated that there are 5 variables that significantly impact the adoption of climate change adaptation practices among farming communities, while 6 variables were identified for fishing communities. A sustainable climate change adaptation plan was proposed emphasizing simple access to loans, climate change training, government and non-government aid, livelihood diversification, and four implementation techniques.

本文旨在解决在评估孟加拉国库尔纳地区沿海地区渔业和农业社区采用气候变化适应实践的方法缺陷。本文阐述了适应指数的推导，考虑了基于其有效性、可行性和可持续性的适应实践的权重，以及农业和渔业社区家庭采用的实践数量。通过焦点小组讨论、住户问卷调查和工作坊收集的数据，建立住户适应指数平均值。在渔业社区共进行了123次家庭调查，同时在农业社区进行了125次家庭调查。此外，在Dacope upazila举行了8次焦点小组讨论和8次讲习班。Sutarkhali渔业社区的适应指数最高，而Bajua农业社区的适应指数最高。多元回归分析表明，有5个变量对农业社区采取气候变化适应措施有显著影响，而6个变量对渔业社区有显著影响。提出了一个可持续的气候变化适应计划，强调简单的贷款渠道、气候变化培训、政府和非政府援助、生计多样化和四种实施技术。

Coastal communities in general have been studied in the context of disaster. However, the specific responses of fishing communities to tropical cyclone events remain relatively under-explored in the disaster science literature. This study investigates fishers' responses to tropical cyclones and various factors that impact behavioral decisions on whether to go to a cyclone shelter. The findings suggest that fishers' coping mechanisms involve securing daily necessities through their initiatives, reliance on kinship relations and obligations, diversification of livelihoods, intensification of fishing, and engagement in social networking and environmental management. The findings suggest that approximately half of the participants refrained from seeking refuge in cyclone centres for various reasons. Crucially, the socio-economic and occupational status of fishing communities significantly influenced their reluctance to comply with evacuation orders. Recognizing non-compliance with evacuation orders is a leading factor in cyclone-related human fatalities and addressing and mitigating non-compliance is essential. Integrated and comprehensive approaches, including cross-sector cooperation, will be needed for effective disaster risk management strategies within small-scale fishing communities.

沿海社区一般都是在灾害背景下进行研究的。然而，在灾害科学文献中，渔业社区对热带气旋事件的具体反应仍然相对较少。本研究调查了渔民对热带气旋的反应，以及影响他们是否前往气旋避难所的行为决策的各种因素。研究结果表明，渔民的应对机制包括通过自己的主动行动、依赖亲属关系和义务、生计多样化、渔业集约化以及参与社会网络和环境管理来获得日常必需品。调查结果表明，由于各种原因，大约一半的参与者没有在气旋中心寻求庇护。至关重要的是，渔业社区的社会经济和职业地位在很大程度上影响了他们不愿遵守疏散命令。认识到不遵守疏散命令是造成与飓风有关的人员死亡的主要因素，处理和减轻不遵守命令的情况至关重要。要在小规模渔业社区内制定有效的灾害风险管理战略，就需要采取综合和全面的办法，包括跨部门合作。

Investments, including those allocated for Disaster Risk Reduction (DRR), need to be appraised before project implementation. Despite scholars' efforts to evaluate DRR investments over the years, a notable gap exists in the literature regarding systematic reviews focused on this topic. Therefore, this study aims to address this gap by conducting a systematic literature review of previous studies assessing the feasibility of DRR investments. The dataset for this review comprised 87 articles sourced from the Scopus database. The findings have been presented according to the research questions of the study, the methods used for appraisal of DRR investments, the types of costs and benefits considered, and the strengths and limitations identified by studies related to the appraisal techniques. Additionally, bibliographic data, the types of hazards considered for DRR investments, and the study contexts were identified. Notably, a significant portion of studies focused on the USA, with investments for flood mitigation representing the majority of investment appraisals. The findings highlighted that cost-benefit analysis was the predominant method used for evaluating DRR investments. Generally, cost estimation was straightforward, which included the initial investment and the maintenance expenses. However, discrepancies exist in the benefits considered by different researchers and the approaches used to quantify them. Based on these findings, the authors suggest future research directions and recommendations aimed at enhancing investment appraisals for DRR.

投资，包括为减少灾害风险（DRR）分配的投资，需要在项目实施前进行评估。尽管学者们多年来一直在努力评估DRR投资，但关于这一主题的系统综述的文献中存在明显的差距。因此，本研究旨在通过对以往评估DRR投资可行性的研究进行系统的文献综述来解决这一空白。本综述的数据集包括来自Scopus数据库的87篇文章。研究结果是根据研究的研究问题、评估减灾风险投资所使用的方法、所考虑的成本和收益类型以及与评估技术有关的研究确定的优势和局限性提出的。此外，还确定了文献数据、DRR投资考虑的危害类型和研究背景。值得注意的是，很大一部分研究集中在美国，投资评估的大部分是用于防洪的投资。调查结果突出表明，成本效益分析是评价减少灾害风险投资的主要方法。一般来说，成本估算是直截了当的，它包括初始投资和维护费用。然而，不同的研究人员所考虑的益处和用于量化它们的方法存在差异。在此基础上，作者提出了未来的研究方向和建议，旨在加强风险风险投资评估。

Growing climatic variability and rapid urbanization have increased landslide occurrences, posing significant challenges for risk assessment. Traditional paper-based evaluation methods, still widely used in South Korea, are time-consuming, prone to errors, and incapable of real-time analysis, limiting their effectiveness in disaster management. This study aims to address these inefficiencies by developing the Steep Slope Risk Assessment Tool (SSRAT), a digital platform designed to modernize landslide risk evaluations and improve decision-making. To achieve this, a scoping review was conducted to identify gaps in existing assessment methodologies, followed by a targeted survey of risk management professionals to understand practical challenges in the field. These insights informed the design of SSRAT, which features streamlined data entry, automated scoring, and real-time risk analysis. The tool's proof-of-concept validation through user testing demonstrated enhanced work efficiency, improved data integrity, and heightened risk awareness. The findings suggest that SSRAT has the potential to support adaptive landslide management and influence national disaster policies. Future research should extend pilot studies across diverse regions and climatic conditions to refine its functionality and facilitate broader adoption in disaster risk management practices.

日益增长的气候变化和快速的城市化增加了山体滑坡的发生，给风险评估带来了重大挑战。传统的基于纸张的评估方法在韩国仍被广泛使用，但这些方法耗时长、容易出错、无法进行实时分析，限制了它们在灾害管理中的有效性。本研究旨在通过开发陡坡风险评估工具（SSRAT）来解决这些低效率问题，这是一个旨在实现滑坡风险评估现代化和改进决策的数字平台。为了实现这一目标，进行了范围审查，以确定现有评估方法中的差距，然后对风险管理专业人员进行了有针对性的调查，以了解该领域的实际挑战。这些见解为SSRAT的设计提供了依据，其特点是简化数据输入、自动评分和实时风险分析。通过用户测试，该工具的概念验证证明提高了工作效率，改善了数据完整性，并提高了风险意识。研究结果表明，SSRAT具有支持适应性滑坡管理和影响国家灾害政策的潜力。未来的研究应将试点研究扩展到不同的地区和气候条件，以完善其功能，并促进在灾害风险管理实践中更广泛地采用。

Droughts are severe climate-related disasters that significantly impact water resources, agriculture, ecosystems, and communities, causing widespread damage. This review delves into the vulnerability, severity, preparedness, and response to drought disasters, focusing on water governance and policies in response to increasing water shortages. The study used documentary and content analysis to examine the existing water policy framework, based on peer-reviewed articles and government technical-based and strategic documents from water departments. South Africa's water governance and policy structures face challenges due to topographical complexities, limited land, climate change, bureaucratic hurdles, reactive government approaches, limitations in water law and policy framework documents, and persistent inequalities. These studies reveal research gaps in ecosystem-based drought adaptation and indigenous practices, emphasizing the need for inclusive knowledge generation and improved drought management coordination to address social vulnerability. The SWOT analysis reveals strengths, weaknesses, opportunities, and threats of current water governance policies, providing practical solutions for drought preparedness and sustainability. The findings reveal that South Africa's water scarcity is not solely due to climate change but also political negligence, institutional factors, and inadequate coordination of drought relief programs, indicating significant preparedness and response gaps. Accordingly, this study proposes a comprehensive model for managing drought disasters and improving water resources to mitigate water shortages and climate change impacts, advocating for a governance culture that promotes holistic and adaptive approaches to sustainable development goals (SDGs). In conclusion, two enablers of transformational governance and transformative policy approach in the water sector serve as key policy modifications for sustainable and equitable water resources management.

干旱是与气候有关的严重灾害，对水资源、农业、生态系统和社区造成严重影响，造成广泛破坏。本综述深入探讨了干旱灾害的脆弱性、严重程度、准备和应对措施，重点是应对日益严重的水资源短缺的水治理和政策。这项研究利用文献和内容分析，根据同行评议的文章和水务部门的政府技术和战略文件，审查了现有的水政策框架。由于地形复杂性、有限的土地、气候变化、官僚主义障碍、被动政府方法、水法和政策框架文件的局限性以及持续的不平等，南非的水治理和政策结构面临挑战。这些研究揭示了基于生态系统的干旱适应和土著实践方面的研究差距，强调需要包容性知识的产生和改善干旱管理协调，以解决社会脆弱性问题。SWOT分析揭示了当前水资源治理政策的优势、劣势、机遇和威胁，为干旱防范和可持续发展提供了切实可行的解决方案。研究结果表明，南非的水资源短缺不仅仅是由于气候变化，还包括政治疏忽、制度因素和干旱救援计划协调不足，表明了重大的准备和响应差距。因此，本研究提出了一个管理干旱灾害和改善水资源的综合模型，以减轻水资源短缺和气候变化的影响，倡导一种促进整体和适应性方法实现可持续发展目标（sdg）的治理文化。总之，水部门变革型治理和变革型政策方法的两个推动因素是可持续和公平水资源管理的关键政策修改。
