内容説明
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:
provides a comprehensive set of methods for water footprint assessment
shows how water footprints can be calculated for individual processes and products, as well as for consumers, nations and businesses
contains detailed worked examples of how to calculate green, blue and grey water footprints
describes how to assess the sustainability of the aggregated water footprint within a river basin or the water footprint of a specific product
includes an extensive library of possible measures that can contribute to water footprint reduction.
