During the last two decades, the expansion and intensification of agriculture have increased through the development of various surface water storage projects to support agriculture development. In this scenario, understanding the complete water balance under different land use and climate is required for the sustainable management of water resources and agriculture development. The present study attempted to quantify integrated hydrological processes under changing land use and climate over three decades from 1985 to 2018 with the help of coupled SWAT-MODFLOW. The study quantified the river-aquifer interactions and dynamic groundwater recharge by implementing dynamic land use and climate in the coupled hydrological model for three decades. The integrated model has revealed that the combined impact of land use change and climate has increased runoff by 26%, percolation by 16%, irrigation water requirement by 48%, and groundwater storage has declined by 20%, by the end of 2018 when compared to 1991. The present study emphasized the need of modelling surface–groundwater in an integrated manner for better understating hydrological processes to support sustainable water resource management.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"17 ","pages":"Article 100129"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46199240","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}

Based on an in-depth examination of the BBB concept and its relevance to risk management, we propose an adapted methodological approach suitable for the Paris Region critical infrastructures. Finally, the approach, initially designed for a reconstruction context, is implemented to reduce the vulnerabilities of infrastructures in the prevention phase. We then talk about build better before and present here a development in this sense. Our proposed framework is structured into two major axes: risk quantification and decision support for the multi-criteria optimization of the investments required to mitigate the quantified risks. With this in mind, we first propose to develop an FMEA (Failure Mode and Effects Analysis) in order to identify and formalize the direct and indirect vulnerabilities of critical infrastructures in a flooding context. The output of the risk assessment is then used within a multi-criteria optimization framework for optimal risk reduction under budget constraints.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"17 ","pages":"Article 100123"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41966648","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}

Six attributes that together provide a foundation for good governance to reduce future water risks to food systems are proposed. These attributes dovetail in their dual focus on incorporating adaptive learning and new knowledge, and adopting the types of governance systems required for water resilient food systems. The attributes are also founded in the need to greater recognise the role natural, healthy ecosystems play in food systems. The attributes are listed below and are grounded in scientific evidence and the diverse collective experience and expertise of stakeholders working across the science-policy interface: Adopting interconnected systems thinking that embraces the complexity of how we produce, distribute, and add value to food including harnessing the experience and expertise of stakeholders s; adopting multi-level inclusive governance and supporting inclusive participation; enabling continual innovation, new knowledge and learning, and information dissemination; incorporating diversity and redundancy for resilience to shocks; ensuring system preparedness to shocks; and planning for the long term.

This review uses tools from bibliometrics and network science to explore overlap and collaboration of scholars studying transboundary water resources and water security management. We explore intersections between these communities through an analysis of publications trends, a content analysis of abstracts using natural language processing, and co-authorship networks. We glean five key findings from our results, including that slight variations in keywords used in the literature search in these two topic areas result in different communities of scholars and publications. Our results show that while publications on these topics are increasing over time and there is meaningful overlap between the two topics, the number of scholars publishing in both areas is not increasing over time. The co-authorship networks demonstrate that few authors participate in both transboundary water resources and water security management research communities, and that authors who have knowledge from both topic areas are uniquely positioned within their social networks to facilitate collaboration. We find no correlation between the betweenness centrality and the citation count for authors, measures which are both used to evaluate author influence. The content analysis of abstracts reveals important areas of overlap in the topics addressed, such as climate change, development, and governance, as well as areas of dissimilarity in the scales and focus of these works. Although we found that the broad scope of the water security framework included some of the most prominent scholars studying transboundary water resources, much of the transboundary water resource scholarship was not captured by water security keywords. This work demonstrates that if we are to continue to use integrative yet actionable frameworks in the pursuit of convergent water research, we must think carefully about how we craft these frameworks and whether our choice of language is constructive or destructive in bringing together relevant scholars and research.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"16 ","pages":"Article 100117"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2468312422000086/pdfft?md5=7783d717239aa64f8f50f66abb1fe90b&pid=1-s2.0-S2468312422000086-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"55186355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
