Both subjective and objective risk evaluations are of great significance in reducing the influence of calamities and devising comprehensive plans for risk governance. Although some studies have identified differences between subjective and objective risks, a detailed analysis of their underlying causes is lacking. These disparities in risk perception can lead to an uneven allocation of resources. Factors influencing risk perception directly or indirectly impact a region’s potential resilience and preparedness for disasters. Socio-demographic factors emerged as critical determinants of flood risk perception disparities. This study aims to integrate both risk assessments to explore the reasons behind these differences. Using six central districts in Nanjing as a case study, the research utilized SPSS and GIS for processing the assessments, and applied a comprehensive analysis method to probe into the elements that have an impact on how people perceive the risk of floods. The findings indicated that Jianye and Gulou districts had high objective risk but low subjective risk, while Qinhuai and Yuhuatai presented low objective risk but high subjective risk. Notably, socio-demographic variables such as gender, education, flood experience, and disaster education exhibited district-specific influences on risk perception, explaining the differences between subjective and objective risks. Additionally, the factors influencing how residents perceive flood risk varied across districts. These discoveries can assist governments in implementing targeted flood protection measures and developing comprehensive rescue strategies that address both physical vulnerabilities and psychological perceptions of risk.</div></div>","PeriodicalId":101279,"journal":{"name":"Water-Energy Nexus","volume":"8 ","pages":"Pages 189-204"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144514171","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}

Samples were exposed to ozone for varying durations, namely 0, 15, and 25 min, with real-time monitoring of key water quality parameters using a HANNA multiprobe, including temperature, pH, electrical conductivity (EC), resistivity, total dissolved solids (TDS), salinity, and oxidation–reduction potential (ORP).

Several models such as ANFIS-M1, ANFIS-M2, SVR-M1, SVR-M2, RLR-M1, and RLR-M2 (α, β, γ, Δ, ε, ζ variations) were developed and evaluated. Based on the performance evaluation metrics, ANFIS-M1 consistently demonstrated superior performance, while SVR-M2 and RLR-M2 exhibited greater variability and generally lower accuracy.

Yet, little attention has been paid to these TOs and SYs, with most concentrating on the securities that are both a pre-requisite and consequence of a nexus interaction. This is in lieu of further (un)conscious alienation of the household pre-requisites that drive these TOs and SYs. This study assessed the determinants of TOs and SYs in the household F-W-E nexus. A cross-sectional survey was employed targeting 655 randomly selected households in the Amathole District of South Africa. Trade-offs and synergies within the F-W-E nexus were quantified based on the experiences reported by households in the study area and were normalised using min–max normalisation. The study employed a Tobit regression model to examine the factors driving these TOs and SYs within the F-W-E nexus. A trade-offs and synergy index (TSI) of 53.7% was revealed suggesting that most of the respondents in the study area face more TOs than SYs in the F-W-E nexus. Additionally, the TSI was negatively influenced by household size, access to credit, participation in farming activities and increases in food prices. In conclusion, the study argues that socio-economic factors drive the household level F-W-E nexus TOs and SYs.

Scholarly literature and policy arenas increasingly embrace the water-energy-food (WEF) nexus as an innovative strategy for tackling intricate resource and developmental issues. Despite the conceptual promise of the WEF nexus, its practical application in systematically assessing interconnections and facilitating the formulation of pertinent resource policies has remained limited.

A comprehensive analysis of 770 research articles sheds light on the evolving research landscape across various countries and their interconnectedness within the WEF nexus over time. Through analysing case studies and theoretical frameworks, the review underscores the importance of collaboration among stakeholders and interdisciplinary research to achieve sustainable agricultural systems. This study not only elucidates the diverse interconnections within the WEF nexus but also introduces three distinct conceptual frameworks; the interplay between WEF sectors, the intricacies of WEF interactions in agricultural production, and the untapped potential of the WEF nexus in agriculture.

The study focuses on application of the concept in semi-arid and arid Sahel regions, which receive ample solar radiation throughout the year for renewable energy production and have precipitation amounts between 150 and 850 mm a<sup>−1</sup>. The incentives for developing the concept were inaccessibility to electricity, lack of water for domestic and agricultural uses and environmental and public health issues caused by use of feelgood and poor domestic water quality. The study shows that a minimum precipitation of about 200 mm a<sup>−1</sup> is needed to obtain a net rainwater harvesting yield surplus after accounting for evaporative and PV panel cleaning losses and hydrogen production water needs.

For Tier 4 household energy supply (4.5 kWh d<sup>−1</sup>), which allows for electric cooking, fixed-tilt solar power system rainwater harvesting can provide 2–7% of unit household water demand, whereas a PV-powered hydrogen production plant can provide up to 50% per kg hydrogen produced in the Sahel. Corresponding values for regions south of the Sahel are over 25% and well over 100%, respectively. Siting criteria for combined rainwater harvesting and PV energy systems include precipitation and water storage aspects, in addition to those for solar energy harvesting.

The mismatch between available water resources and the demands of energy production, food production, and ecological water use has intensified the interdependence and competition among these sectors, becoming a major constraint on high-quality development. To assess the collaborative security and coupling coordination of Yulin’s WEFE<sub>co</sub> nexus, this study constructs an evaluation indicator system and model, analyzing statistical data from 2000 to 2020. The results show that the synergetic security index of Yulin’s WEFE<sub>co</sub> nexus fluctuated upward over the period, indicating an improvement in the overall synergetic security. However, the index remains below 0.6, suggesting that further strengthening of water resource management, optimizing energy production, improving food production capacity, advancing ecological protection, and enhancing interdepartmental cooperation are necessary. The analysis also reveals four stages of coupling coordination in Yulin’s WEFE<sub>co</sub> nexus: 1) 2000–2008, a transitional stage with rapid economic growth but lagging management; 2) 2009–2014, a basic coordination stage with improved management measures, though still insufficient; 3) 2015–2017, a period of decline in coordination, characterized by near-coordination development and mild disorder due to environmental and social changes; and 4) 2018–2020, a basic coordination stage where reforms and policies led to improved coordination.
