主 题：Virtual Water and Water Footprint in the Globalization of Water Resources
主讲人：EAWAG首席科学家，Prof. Hong Yang
Water is mostly a local resource, which is confined to a river basin. However, water can be moved ‘virtually’ from one region/basin to another through international/regional trade of commodities, the so called ‘Virtual Water Trade’ - redistribution of water resources. Water use and virtual water trade can impose impact on source and destination countries of the trade. This impact can be measured by Water Footprint. This lecture will introduce the concepts of virtual water and water footprint and their applications in accounting for global water uses and virtual water flows, as well as impacts on sources and destinations of the trading countries. It will focus on the following issues: virtual water and water footprint in the context of globalization of water resources, virtual water trade in compensating for water scarcity, relations and differences between virtual water and water footprint, colors of virtual water and water footprint and their implications for water management, methodologies used in assessing virtual water and water footprint.
