Las regiones semiáridas tienen problemas de escasez de agua, agravados por la contaminación. Este libro recoge experiencias de expertos en el dominio de la gestión de las aguas en regiones áridas y semiáridas, con ejemplos sobre Libia o el SW de Estados Unidos. Se analizan la problemática almeriense y el ejemplo paradigmático del abastecimiento a Murcia. La simulación numérica de la contaminación de acuíferos, o un interesante enfoque del agua en la minería, completan una obra de consulta obligada para los especialistas.

This book provides a systematic and comprehensive guide to the current state of knowledge on tourism and water. It is the first book to thoroughly examine the interrelationships of tourism and water use based on global, regional and business perspectives. Its assessment of tourism's global impact along with its overviews of sectoral and management approaches will provide a benchmark by which the water sustainability of tourism will be measured for years to come. In making a clear case for greater awareness and enhanced water management in the tourism sector, it is hoped that the book will contribute to the wise and sustainable use of this critical resource. The book is interdisciplinary in coverage and international in scope. It is designed as essential reading for not only students of tourism but also practitioners.
Desalination Sustainability: A Technical, Socioeconomic, and Environmental Approach presents a technical, socioeconomical, and environmental approach that guides researchers and technology developers on how to quantify the energy efficiency of a proposed desalination process using thermodynamics-based tools. The book offers the technical reader an understanding of the issues related to desalination sustainability. For example, technology users, such as public utility managers will gain the ability and tools to assess whether or not desalination is a good choice for a city or country. Readers will learn new insights on a clear and practical methodology on how to probe the economic feasibility of desalination using simple and effective tools, such as levelized cost of water (LCOW) calculation. Decision-makers will find this book to be a valuable resource for the preliminary assessment of whether renewable-powered desalination is a good choice for their particular setting. Presents the issues related to desalination sustainability Guides researchers and technology developers on how to quantify the energy efficiency of a proposed desalination process using thermodynamics-based tools Outlines a clear and practical methodology on how to probe the economic feasibility of desalination using simple and effective tools Provides a roadmap for decision-makers on the applicability of a desalination process at a particular setting
High-energy consumption is a critical issue associated with seawater reverse osmosis (SWRO) desalination, although the SWRO has been regarded as one of the most energy-efficient processes for seawater desalination. This means that SWRO involves a larger amount of fossil fuel and other energy sources for water production, which imposes a negative impact on the environment such as greenhouse gas emission. Therefore, the high-energy consumption of SWRO should be addressed to minimize environmental impacts and to allow for sustainable exploitation of seawater. However, the recent trend of energy consumption in SWRO seems to have reached a saturation point, which is still higher than theoretical minimum energy. To find new and innovative strategies for lowering current energy consumption, a comprehensive understanding of energy use in SWRO plants from theoretical analysis to actual energy consumption in real SWRO plants is required. This book can provide readers with information about the current state of energy consumption in actual SWRO plants, the fundamental understanding of energy use of SWRO plants from theoretical point of view, and advanced technologies and processes that could be applied for future energy reduction. In addition, this book will offer a detailed methodology for analyzing energy issues in seawater desalination. Through this book, readers will obtain an insight into how to deal with and analyze the energy issues in SWRO desalination.
This book provides an overview, by leading world experts, on key issues in global water and food security. The book is divided in a series of over-arching themes and sections. The first part of the book provides an overview of water and food security. The second and third sections look at global trade and virtual water trade, and provide some
