Book Description
Provides critiques of current practices for environmental flow assessment and shows how they can be improved, using case studies. In Environmental Flow Assessment: Methods and Applications, four leading experts critique methods used to manage flows in regulated streams and rivers to balance environmental (instream) and out-of-stream uses of water. Intended for managers as well as practitioners, the book dissects the shortcomings of commonly used approaches, and offers practical advice for selecting and implementing better ones. The authors argue that methods for environmental flow assessment (EFA) can be defensible as well as practicable only if they squarely address uncertainty, and provide guidance for doing so. Introductory chapters describe the scientific and social reasons that EFA is hard, and provide a brief history. Because management of regulated streams starts with understanding freshwater ecosystems, Environmental Flow Assessment: Methods and Applications includes chapters on flow and organisms in streams. The following chapters assess standard and emerging methods, how they should be tested, and how they should (or should not) be applied. The book concludes with practical recommendations for implementing environmental flow assessment. Describes historical and recent trends in environmental flow assessment Directly addresses practical difficulties with applying a scientifically informed approach in contentious circumstances Serves as an effective introduction to the relevant literature, with many references to articles in related scientific fields Pays close attention to statistical issues such as sampling, estimation of statistical uncertainty, and model selection Includes recommendations for methods and approaches Examines how methods have been tested in the past and shows how they should be tested today and in the future Environmental Flow Assessment: Methods and Applications is an excellent book for biologists and specialists in allied fields such as engineering, ecology, fluvial geomorphology, environmental planning, landscape architecture, along with river managers and decision makers.

Book Description
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

Book Description
This book provides an in-depth analysis of existing methods of water management and highlights the gaps in the use of water in various river basins. Underlying the futility of 'quick fix' solutions, it puts forward various alternative strategies for water management. Using illustrative case studies, the author lists major challenges in water management: productivity improvement in key-use sectors, inter-sectoral allocation, trans-boundary resource management, and availability in deficient regions. Highlighting the opportunities for improving water productivity in agriculture, he also provides methodologies for generating country- and regional-level water balance scenarios. The volume also discusses the problems involved in allocating water in river basins. Kumar gives a detailed account of some of the widely known economic tools. He examines the institutional and policy measures for ensuring sustainable use of water and economic growth, including the creation of new organizations.

Book Description
Virtual Water explores the role of "virtual water" – the water embedded in a product – in ongoing conversations of agriculture, trade and sustainability in an increasingly inter-connected world. A pervasive theme throughout the book is the general lack of knowledge of the use of water in producing and consuming food. The chapters, arising from a workshop supported by the OECD Co-operative Research Programme: Biological Resources Management for Sustainable Agricultural Systems, on virtual water, agriculture and trade at the University of Nebraska-Lincoln, consider questions of gaps in knowledge, why sustainability matters and the policy implications of virtual water trade. Contributors show how water is a lens through which to examine an array of vital issues facing humanity and the planet: human and animal health; food production; environmental management; resource consumption; climate change adaptation and mitigation; economic development, trade and competitiveness; and ethics and consumer trust. Virtual Water will be of great interest to scholars of water, resource management and consumption, the environmental aspects of development, agriculture and food production. It originally published as a special issue of Water International.

Book Description
The factors affecting water quality are many: The increasing buying power and health concerns of the world population contribute to the creation of new products whose production and disposal lead to the release of chemicals harmful to the environment; the ever-growing world population requires a steady food supply, which increases the pressure to use even more chemicals to control various crop pests; and due to climate change, head waters, rivers, and oceans are becoming increasingly warmer, acidic, and eutrophic as the result of carbod dioxide overload. Using specific examples, Water Quality and Resource Management will address the many challenges of providing clean water to the growing world population. It will also discuss the new technologies that are being developed, for example, to treat and reuse waste waters, and the innovative monitoring approaches that help scientists to assess water quality risks. Such risk assessments are urgently needed to help draft legislations and allow enforcement to ensure accessability to quality water for all. The structure of the book will be the following: Each chapter will provide information about a specific water environment and the challenges it faces. This will be followed by discussion of the pollution effects and actions taken to redress the situation. Finally, future trends will be discussed.

Book Description
India is a large country with regional differences in per-capita water supply and demand. Attempts to describe the water situation in India at a national level are often misleading due to the tremendous diversity in the water situation across the country. This Report analyzes the spatial variation of water supply and demand across river basins in India. The study identifies basins that are water-scarce because of inadequate water availability to meet the effective demand. It also identifies issues that are important for estimating the future water demand and for the formation of policy for future water-resources development and management.
