Dew Harvest deals with dew harvesting as a feasible solution to the chronic water scarcity in arid areas near the coastline. It substantiates the methodology of dew harvesting based on a case study from the Kothara village in the Kutch region. The book provides insights into the simple and people friendly technology of dew harvesting. It explains the exemplary procedure that Prof. Sharan followed: study of the dew resource of the site, chemical analysis of dew water to verify potability, test of dew harvesting materials, construction of small and pilot-sized dew condensers, and ultimately the construction of a large dew production plant. The author describes the methodology involved in the measurement of dewfall throughout India, especially in the coastal regions. The author recommends that dew harvesting be part of the curriculum at colleges and urges hydrologists and engineers to seriously consider its utility as an innovative technology. This book is the summary then of present technology to harvest dew water through simple and inexpensive means.

« "Rainwater Harvesting for Drylands and Beyond, Volume 1' is the first book in a three-volume guide that teaches you how to conceptualize, design, and implement sustainable water-harvesting systems for your home, landscape, and community. The lessons in this volume will enable you to assess your on-site resources, give you a diverse array of strategies to maximize their potential, and empower you with guiding principles to create an integrated, multi-functional water-harvesting plan specific to your site and needs. »--

Now established worldwide as the standard guide to the recognition and understanding of the causes of deterioration in temperate and tropical fruits and vegetables, these two superbly illustrated full-colour volumes deal clearly, concisely and systematically with each of the main diseases and disorders, emphasising those of importance to international trade. Dr Snowdon has designed each volume to be used in two different ways: 1. Full colour photographs and practical text provide the basis for preliminary identification by the owner or surveyor. 2. Using the microscope drawings and references, diagnosis can then be confirmed or modified by a specialist.

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.
