Book Description
The commercial operation of atmospheric water harvesting systems is still limited to few countries; this is mainly due to the low energy efficiency of the system and the inability to effectively operate throughout the various seasons of the year. Researchers have attempted to develop strategies to render the operation of atmospheric water harvesters easier and cost effective. This book covers work progress toward such direction, including among others the co-operation of these systems with renewable energy source and the adaptation of the systems to local conditions; the response of the communities around the world to such technology and how its implementation is affected by cultural believe, cost, and technological friendliness. The book is of interest to academic researchers, students, water authorities, professional in relevant industries, government regulatory bodies officers, and environmentalists.

Book Description
The world’s ever-increasing need for fresh water has led to the use of non-conventional sources such as rain and fog water collection. Although rain water collection is relatively simple, the supply is often erratic. Passive fog water collection has been used in several parts of the world but is only relevant to certain geographical locations. Dew occurrence, however, is far more widespread, can form in most climates and geographic settings, show high frequency and prevalence throughout the year. During the past 20 years, dew collection has therefore been investigated as a serious supplemental source of fresh water. Dew Water offers a thorough review of dew, its formation characteristics and potential for dew collection, for audiences that include policy-makers, non-governmental organizations involved in development aid and sustainable development, engineers, urban planners, researchers and students.After providing a background on atmospheric water, humid air, and sky and materials emissivity, the book deals with dew formation and its estimation with a focus on the use of meteorological data. Dew measurement techniques are reviewed and discussed as well as dew collection by passive means. Computational fluid dynamics technique is described for better design of dew collectors. Dew quality (chemistry, biology) is assessed in view of potable water quality. Costs and economic aspects are also considered.

Book Description
For many people, thoughts of the United Arab Emirates conjure images of ultramodern skyscrapers and rolling sand dunes. However, the Emirates are a rich mosaic of ecosystems and habitats that support surprisingly diverse communities of organisms, and there is growing awareness of the importance of these previously underappreciated natural assets. A Natural History of the Emirates provides a comprehensive overview of the unusual environmental setting of this young nation, and surveys the major ecosystems and the marine and terrestrial organisms occurring across the nation. From freshwater streams in the hyperarid Hajar Mountains to the world’s most temperature-tolerant coral reefs, the UAE is home to an astounding variety of uniquely adapted organisms that are providing insights into climate change and how organisms cope with and respond to extreme environmental conditions. The book closes with a section on human interactions with this unique environment, and proposes initiatives to ensure the protection of these unique natural assets into the future. This is an open access book.

Water harvesting is gaining more and more recognition as a sustainable and resilient water supply options. It is economically viable, socially compatible and environmentally friendly. Water harvesting has proven to be a robust solution to overcome or reduce water shortages all over the world. It is important to understand how to apply this practice in a sustainable and effective way to make full use of its potential in a world increasingly threatened by water scarcity. The Handbook of Water Harvesting and Conservation: Basic Concepts and Fundamentals is the most comprehensive, up-to-date and applied handbook on water harvesting and conservation yet published. The book’s 30 chapters -- written by 84 outstanding international experts from approximately 20 selected countries faced by drought -- explore, critique and develop concepts and systems for water harvesting. The editors bring together many perspectives into a synthesis that is both academically based and practical in its potential applications. The Handbook of Water Harvesting and Conservation: Basic Concepts and Fundamentals is an important tool for education, research and technical works in the areas of soil, water and watershed management and is highly useful for drought strategy planning, flood management and developing techniques to adapt to climate change in urban, agricultural, forest and rangeland areas.

Book Description
Water shortage is an increasing threat to humankind. Porous sorbent assisted atmospheric water harvesting (psaAWH) has emerged as an effective technological countermeasure. In this review, we summarize the types of porous adsorbents used in psaAWH and provide an overview of their states of development. The water adsorption mechanism and the processes associated with each material are analyzed, and the application prospects of the adsorbents are evaluated. The effect of the inherent properties (pore size, functional group, etc.) of the adsorbent on the water harvesting performance is also discussed. Further, we focus on the water adsorption/desorption kinetics of the adsorbents and outline various methods to improve the kinetics. At this stage, there are many strategies for improving the kinetics of the adsorbent, which in turn influences the adsorption process and intra/inter-crystalline diffusion. However, there is still limited research on the transport of water molecules in microporous adsorbents for psaAWH. Thus, this aspect is re-examined herein from a new perspective (superfluidity) in the review. Based on the discussion, we can reasonably infer that water molecule superfluidity can exist in nanoconfined channels, thus promoting the rapid transport of water molecules. The formation of water superfluidity is a feasible strategy for improving the intracrystalline diffusion of the psaAWH adsorbent. Finally, we consider the future developments and challenges of psaAWH in detail. We think this review can serve as a guide for further research in this ever-expanding field.

Book Description
Atmospheric water is a vast freshwater resource and it could potentially relieve billions of people worldwide from water shortage. A number of nature-inspired surfaces have been developed to enhance water harvesting, specifically, through modification to the surface chemistry or physical structures. However, conflicting results were reported regarding the effects of these surfaces, showing that a fundamental understanding of water collection mechanisms on the complex natural and synthetic surfaces is still lacking.In this research effort, the atmospheric water harvesting is studied at the two ends of the possible conditions, i.e., diffusion controlled dew harvesting and convective fog harvesting. For dew harvesting, we theoretically and experimentally show that the total water condensation rate is independent of surface wettability and physical roughness when the thickness of the water vapor concentration boundary layer is significantly larger than that of the physical roughness. The finding defines the lower limit of water harvesting rate from air through condensation. On the other end, a new model based on particle deposition is proposed to describe the fog harvesting process. Droplet deposits are treated as dynamic particle collectors and a droplet roughness parameter is derived to quantify their effect on fog harvesting rate. The model explains why the fog harvesting rate on rough, chemically patterned surfaces can be significantly enhanced compared with flat chemically homogeneous surfaces. The model can also predict the optimal pattern size for fog harvesting, which explains why pattern size of specific length scale is required for Namib Desert beetles to efficiently capture water from air. Furthermore, two novel nature-inspired materials with high surface roughness and efficient water removal mechanisms are developed, which have shown enhanced water harvesting capability.
