One of the most essential and prominent types of security issue faced today is water security, which has introduced a complex and new concept to the literature of today's world. Not only has the current water crisis in most parts of the world increased the risk of military conflicts between countries, but the value of safe water will become even more apparent in the coming decades, which is why water security will have a special importance in the modern world. Water security is a concept that has attracted particular attention in recent decades from various dimensions. Estimates show that by 2100, the planet's population will increase from the current 7.7 billion (7.7 × 109) to 11.2 billion, and that providing adequate safe water for such a population is one of the significant challenges facing humans – because the world's freshwater resources are not just for individual consumption and for the environment, but they are also vital for the agricultural, energy, industrial, and transportation sectors. Therefore, it should be noted that the existing world water resources, both in terms of quantity and quality, are at a critical stage. However, the severity of this problem varies from region to region, with regions such as the Middle East and South Africa at greater risk of water scarcity. Water security is therefore a vital issue for all of us. This chapter first outlines the concept of water security from different perspectives, emphasizing that water security is a multifaceted issue, before finally examining solutions and policies to address to the challenges.","PeriodicalId":234170,"journal":{"name":"Water Resources: Future Perspectives, Challenges, Concepts and Necessities","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131383775","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}

This vast resource deployment was expected to finally decelerate after the emergence of the Sustainable Development paradigm in the late 1980s. The concept of sustainable development aims to balance the tradeoff between supply and the needs of societies to also preserve the needs of future generations. Nonrenewable resources, especially water, have been at the heart of sustainable development goals. Sustainable Water Management (SWM) is an essential component of sustainable development. To achieve SWM, various water management challenges, in both developing and developed countries, should be addressed by attracting stakeholders to invest in water system efficiency and improvement projects, as well as by recycling and reusing water. To assess sustainable management policies and practices, evaluation of performance metrices – such as the Water Resources Sustainability Index, reliability, resiliency and vulnerability, and the Stability Index – is imperative. A cost-efficient policy should also facilitate the attainment of sustainability in all socioeconomic, and environmental sectors.","PeriodicalId":234170,"journal":{"name":"Water Resources: Future Perspectives, Challenges, Concepts and Necessities","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130058521","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}

Nanotechnology is one of the state-of-the-art tools in scientists’ hands which they can use to meet human water needs via reuse of water and utilizing unconventional water resources. Additionally, monitoring water supply systems using new nanomaterials provides more efficient water distribution networks. In this chapter, we consider the generic concepts of nanotechnology and its effects on water resources management strategies. A wide range of nanomaterials and nanotechnologies, including nano-adsorbents, nano-photocatalysts, and nano-membranes, are introduced to explain the role of nanotechnology in providing new water resources to meet growing demand. Also, nanomaterial application as a water alternative in industry, reducing water demand in the industrial sector, is presented. Another revolution made by nanomaterials, also discussed in this chapter, is their use in water supply systems for monitoring probable leakage and leakage reduction. Finally, we present case studies that clarify the influence of nanotechnology on water resources and their management strategies. These case studies prove the importance and inevitable application of nanotechnology to satisfy the rising water demand in the modern world, and show the necessity of nanotechnology awareness for today's water experts.","PeriodicalId":234170,"journal":{"name":"Water Resources: Future Perspectives, Challenges, Concepts and Necessities","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133082215","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}

Since the amount of renewable water the Earth receives is only equal to, or even less than, that received many years ago, renewable water per capita decreases as human population increases. Inter-basin water transfer is a method to augment supply in water-scarce regions.\u0000 Increasing demand for water in some areas sometimes justifies the transfer of water from one basin to another. Water consumption in densely populated cities and in large industrial and agricultural operations produces an economic value that justifies the cost of expensive water transport equipment and infrastructure such as transmission channels, pipelines, pumping stations and dams. Under these conditions, water that is not in high demand in one basin is transferred to another basin for use. These projects are supply-driven engineering solutions to major social challenges. Inter-basin water transmission is carried out across local, regional, national, and international boundaries to overcome water scarcity, to meet demand in the agricultural, industrial and domestic sectors as well as to achieve economic and social development.\u0000 Inter-basin transfer (IBT) is an important water resource management tool that can have significant impacts on the donor and recipient basins. This chapter aims to provide insights into the concepts, logics, methods and tools used to evaluate inter-basin transfer projects. Challenges that may arise with implementation of such projects and management methods to overcome these challenges are reviewed. Several case study examples of existing projects are presented to provide insight into how to better manage such projects in the future.","PeriodicalId":234170,"journal":{"name":"Water Resources: Future Perspectives, Challenges, Concepts and Necessities","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129733077","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}
