Overview of WLVC
• Background: WWDR and awareness raising
• Rationale for WLVC: Coverage of livestock, Water scarcity and GHG (CO2,
NOx, CH4)• Model of Quadrants• Open questions for research
Background
• WWDR: Risks and Uncertainties• Drivers: population change, urban/rural
distribution, lifestyle choices, climate change
• Awareness: when to do what, where and how for whom
Regional meat consumption
Where are the poor livestock raisers(Thornton et al, 2002)
Rationale
• WWDR III, Comprehensive Assessment and Long Shadow: open issues
• New FAO study: GHG from the Dairy Sector
• New US Dairy Study (forthcoming)
�Integral life cycle view emerging�Water community still dispersed by sectors
(From: Ceres, 2009)

Feedback required
• What are the main gaps in the “model”?• Where are the data by context, timeline
and quadrants?• Where are the linkages in research with
consumer organizations, environment and private sector?
