Summary: In recent years, the analysis of social vulnerability to floods has become an important part of flood risk management. However, existing studies often lack a standard procedure and face uncertainties related to indicator selection, inclusion of vulnerability dimensions, weighting methods, and data availability. This paper addresses these gaps by developing a comprehensive methodology that includes a large set of indicators, considers flood-related variables, and applies objective weighting methods. The use of statistical methods and GIS tools provides a better understanding of factors that increase social vulnerability and helps identify highly vulnerable areas for effective flood risk management.

Summary: This paper presents a systematic review and meta-analysis of GIS-based multi-criteria evaluation (MCE) methods used in aquaculture site selection. The main findings indicate a growing number of studies utilizing GIS-based MCE in aquaculture site selection in recent years, with Asia being the leading continent in terms of publications in this domain. Two models have been generated, each consisting of four sub-models, which can aid future researchers and assist decision-makers in identifying optimal locations for aquaculture development.

Summary: This paper introduces multicriteria analysis (MCA) as a practical tool for supporting sustainable decision-making processes. The traditional stages of MCA can lead to uncertainty, which is addressed through uncertainty and sensitivity analyses. Through a concrete material selection problem, the paper demonstrates how to objectively manage methodological uncertainties in MCA.

Summary: Although aquaculture contributes less than 0.2% to Malaysia's GDP, it has become important economically due to high-value species productions. A study in George Town Conurbation found only 0.37% of potential sites for aquaculture, suggesting the need for designated buffer zones to avoid land-use conflicts between urban development and aquaculture.

Summary: Walking is the preferred form of physical activity for most elderly individuals, especially those aged 75 and over. Improving the physical and functional organization of urban areas is crucial for developing safe and comfortable walking paths for the elderly and other vulnerable populations. This study presents a methodology for classifying neighborhoods based on their accessibility for the elderly to reach urban services and tested it in two neighborhoods in Naples.

Summary: This study aims to propose a spatial decision support tool for mapping flood vulnerability in Tehran under different risk scenarios. Several factors were considered, and their weights were determined using expert opinions and the FAHP method. The vulnerability maps for different scenarios were prepared using the OWA method. The results can be used by stakeholders such as urban planners, decision makers, and hydrologists to plan and build resilience against floods.

Summary: This research introduces a new approach to reduce the complexity of vulnerability analysis in infrastructure systems. By framing vulnerability analysis as part of a decision-making process, the focus is shifted to clear and quantifiable requirements of specific end-users. The approach identifies critical components in supply chains by reversing the analysis process and reveals minimum threshold states in which critical supplies will be interrupted. The method also allows the consideration of highly relevant information currently ignored to avoid excessive computational burden.

Summary: This study proposes a modeling framework to quantify the effects of deliberate organic contamination events on water distribution systems by combining bacterial regrowth and chlorine decay models. Vulnerability indexes are used to quantify the impact of each attack and identify critical areas of the network. Sensitivity analysis reveals the network's sensitivity to dynamic variables like mass injection, injection duration, and organic carbon concentration.

Summary: Water distribution networks are critical infrastructure vulnerable to cyber-physical attacks, requiring tools and methodologies to assess system resilience and vulnerabilities. Deployment of water quality monitoring sensors can help protect against water contamination, but attacks on the monitoring system can lead to severe disruptions, emphasizing the need for risk management practices. The study demonstrates a novel methodology for assessing sensor placement schemes under simulated attacks, showing that some designs are more inherently resilient than others.

Summary: Our work examines the biophysical and economic foundations of the Sherwood Plot (SP) and uses it as a framework for measuring resource recovery performance. The SP illustrates the relationship between the cost of recovering a target material from a waste matrix and its dilution in the matrix. We also analyze the SP's physical properties and its economic extensions, and test its validity using real data.

Summary: Understanding the circular economy for water is challenging due to the complexity of the urban water cycle and its interrelations with other factors. To address this challenge, the NextGen Serious Game was developed as an online educational tool to explore the implications of circular economy strategies in different virtual catchments. The game has been successfully used in classrooms, debate facilitation, and even as a competitive tournament for water professionals, contributing to public understanding of water issues.

Summary: Water distribution networks use water quality sensors in contamination warning systems, but compromising these sensors during a contamination event can have devastating consequences for public health. There is an emerging threat of cyber-attacks on these networks, which can intentionally contaminate water and mask the event by attacking the sensors. In this study, we develop an optimization strategy for sensor placement that maximizes resilience under cyber-physical attack scenarios, suitable for designing new layouts or upgrading existing ones. The strategy is tested on multiple networks, with results showing improved detection performance under cyber-physical attacks and minimal performance trade-off under nominal operation, suggesting a good design solution for cyber-wise water utilities.

Summary: Contrary to conventional management, circular economy design principles offer a resource management alternative that reduces waste and promotes efficiency. This study quantitatively demonstrates the links between circularity and resilience in water management, showing that circular water options lead to more resilient water systems. By addressing different circular dimensions, the resilience profiles of water systems become more robust across various water cycle domains.

Summary: This study proposes a method to address the complex socio-technical dynamics and uncertainties in the digital era water system by incorporating socio-technical modeling. It uses a modular process, including estimation of vulnerability-induced probabilities and attack characteristics, generation of threat scenarios, cyber-physical stress-testing, and risk level assessment. By exploring different configurations, it investigates the effects of cyber-security practices and design traits on the modification of utility's risk level.
