TL;DR: In this article, atmospheric water harvesting (AWH) emerges as a promising means to overcome the water scarcity of arid regions, especially for inland areas lacking liquid water sources, and is proposed as an alternative to conventional water harvesting.

TL;DR: Water resource systems analysis as discussed by the authors has been widely used in the field of water resources systems analysis. But it is limited by low scientific and academic visibility relative to its influence in practice and bridled by localized findings that are difficult to generalize.
Abstract: This paper presents a short history of water resources systems analysis from its beginnings in the Harvard Water Program, through its continuing evolution toward a general field of water resources systems science. Current systems analysis practice is widespread and addresses the most challenging water issues of our times, including water scarcity and drought, climate change, providing water for food and energy production, decision making amid competing objectives, and bringing economic incentives to bear on water use. The emergence of public recognition and concern for the state of water resources provides an opportune moment for the field to reorient to meet the complex, interdependent, interdisciplinary, and global nature of today's water challenges. At present, water resources systems analysis is limited by low scientific and academic visibility relative to its influence in practice and bridled by localized findings that are difficult to generalize. The evident success of water resource systems analysis in practice (which is set out in this paper) needs in future to be strengthened by substantiating the field as the science of water resources that seeks to predict the water resources variables and outcomes that are important to governments, industries, and the public the world over. Doing so promotes the scientific credibility of the field, provides understanding of the state of water resources and furnishes the basis for predicting the impacts of our water choices.

TL;DR: In this article, the authors assessed the global costs of meeting the water, sanitation, and hygiene (WASH)-related targets of SDG 6.1 to 6.3.
Abstract: A goal dedicated to clean water and sanitation was recently endorsed by the United Nations General Assembly as part of the Sustainable Development Goals (SDGs) framework for 2015–2030 that has followed the UN’s Millennium Development Goals (MDGs). Drinking water, sanitation, and hygiene form a central part of the clean water and sanitation goal (SDG 6) and are reflected especially in targets 6.1 to 6.3. They are also recognized for their role in reducing health risks as part of the good health and well-being goal (SDG 3) in targets 3.3 and 3.9. This study assesses the global costs of meeting the water, sanitation, and hygiene (WASH)-related targets of SDG 6. It is intended to serve as a vital input to determining the financing needs to achieve them. Two targets are assessed: (1) achieving universal and equitable access to safe and affordable drinking water for all (target 6.1); and (2) achieving access to adequate and equitable sanitation and hygiene for all and ending open defecation (target 6.2). Thus this study presents only a partial analysis of the clean water and sanitation goal, but it can serve as a basis for cost studies of other targets.

TL;DR: The contaminants that develop in the water distribution system and their characteristics are reviewed, as well as the possible transition effects during the switching of treated water quality by destabilization and the release of pipe material and contaminants into the water and the subsequent risks are reviewed.
