1.1 General Framework In most arid and semi-arid countries, water resource management is an issue that is both important and controversial. Most water resources experts now acknowledge that water conflicts are not caused by physical scarcity but are mainly due to poor water management (Rosegrant et al. 2002; Benoit and Comeau 2005; Comprehensive Assessment of Water Management in Agriculture 2007; Garrido and Dinar 2010, among others). The scientific and technological advances of the past 50 years have led to new ways to solve many water-related conflicts, often with tools that seemed unthinkable a few decades ago (Llamas 2005; Lopez-Gunn and Llamas 2008). This study deals with the estimation and analysis of Spain’s water footprint, both from a hydrological and economic perspective. Its ultimate objective is to report on the allocative efficiency of water and economic resources. This analysis can provide a transparent and multidisciplinary framework for informing and optimising water policy decisions, contributing at the same time to the implementation of the EU Water Framework Directive (WFD) (2000/60/EC). It also responds to the current mandate of the Spanish Ministry of Environment and Rural and Marine Affairs, which recently issued instructions for drafting river basin management plans in compliance with the EU Water Framework Directive, with a deadline of end of year 2009 and then every 6 years (BOE 2008).

People use lots of water for drinking, cooking and washing, but significantly more for producing things such as food, paper and cotton clothes. The water footprint is an indicator of water use that looks at both direct and indirect water use of a consumer or producer. Indirect use refers to the 'virtual water' embedded in tradable goods and commodities, such as cereals, sugar or cotton. The water footprint of an individual, community or business is defined as the total volume of freshwater that is used to produce the goods and services consumed by the individual or community or produced by the business. This book offers a complete and up-to-date overview of the global standard on water footprint assessment as developed by the Water Footprint Network. More specifically it: o Provides a comprehensive set of methods for water footprint assessment o Shows how water footprints can be calculated for individual processes and products, as well as for consumers, nations and businesses o Contains detailed worked examples of how to calculate green, blue and grey water footprints o Describes how to assess the sustainability of the aggregated water footprint within a river basin or the water footprint of a specific product o Includes an extensive library of possible measures that can contribute to water footprint reduction

Water Footprints and Sustainable Development serves as the sole comprehensive volume of the role of waste management for sustainable development. It provides an overview of Global Scenario of water footprints in water smart cities and technologies and investigates the critical factors that enable the sustainable developments of various industries in respect to water resources management. The goal of this book is to introduce the reader to the current technologies used for reducing water footprints, and to offer the necessary information and tools for sustainable development. - Provides detailed coverage of the role of Water, Energy and Food Nexus with respect to sustainability - Covers methods such as lifecycle assessment, sustainability assessment, multi-criteria decision-making, and multi-objective optimization modes - Includes key techniques for water resources management and sustainable development

Though the modern Spanish State was formed in the mid Fifteenth Century, historical records show that water works, statues, and the utilization of water dates back to centuries BC. As a semi-arid country, the effort to control, store and assure water supplies to cities and fields is present in numerous historical and political landmarks.Water polic

Integrated water resources management advocates a coordinated approach for managing water resources in a way that balances social and economic needs with concern for the environment. While potentially useful, integrated water management is also controversial. Supporters believe that the multi-dimensional nature of water can only be understood and m

Scholarly interest in water ethics is increasing, motivated by the urgency of climate change, water scarcity, privatization and conflicts over water resources. Water ethics can provide both conceptual perspectives and practical methodologies for identifying outcomes which are environmentally sustainable and socially just. This book assesses the implications of ongoing research in framing a new discipline of water ethics in practice. Contributions consider the difficult ethical and epistemological questions of water ethics in a global context, as well as offering local, empirical perspectives. Case study chapters focus on a range of countries including Canada, China, Germany, India, South Africa and the USA. The respective insights are brought together in the final section concerning the practical project of a universal water ethics charter, alongside theoretical questions about the legitimacy of a global water ethics. Overall the book provides a stimulating examination of water ethics in theory and practice, relevant to academics and professionals in the fields of water resource management and governance, environmental ethics, geography, law and political science.

This book presents various methodologies for determining the ecological footprint, carbon footprint, water footprint, nitrogen footprint, and life cycle environment impacts and illustrates these methodologies through various applications. In particular, it systematically and comprehensively introduces the concepts and tools of the ‘footprint family’ and discusses their applications in energy and industrial systems. The book begins by providing an overview of the effects of the economic growth dynamics on ecological footprint and then presents the definitions, concepts, calculation methods, and applications of the various footprints. The unique characteristic of this book is that it demonstrates the applications of various footprints in different systems including economic system, ecological system, beef production system, cropping system, building, food chain, sugarcane bioproducts, and the Belt and Road Initiative. Providing both background theory and practical advice, the book is of interest to energy and environmental researchers, graduate students, and engineers.
