Key concepts

Virtual water – Total volume of water used to produce a commodity at all points along the production chain
Water footprint – Volume of water used to produce the goods and services consumed by inhabitants of a country.
Includes two components:
Internal water footprint – virtual water of content of all goods and services produced and consumed within a country.
External water footprint – virtual water content of all imported goods and services consumed within a country.

Policy considerations
Water allocation and management policy– Reform water policy to ensure both needs for economic
development and water to sustain ecosystem health are satisfied.
Trade agreements– How have / do existing trade agreements (e.g. NAFTA) influenced
virtual water trade and the related watershed impacts?
– How future trade agreements be designed to include virtual water considerations?
Subsidies– How are government subsidies – for agriculture and for other
sectors – influencing virtual water trade and can / should they be reformed to reduce impacts on ecosystem health?

Internal action
• Engagement in public policy• Shared implementation of strategies to improve
water management at the basin scale
• Companies, governments and NGO’s engaging in multi-stakeholder platforms to asses issues and develop response strategies
• Companies take action to optimize internal water use while measuring and publicly reporting water quantity and quality
• Detailed understanding of the impact companies and their suppliers have on water resources and river basins
• High level understanding of global water challenges, dependence on fresh water and exposure to water related risks
