Water scarcity limits food production
Litre per kilo meat “fears”
Lord Stern:

Blue Water
Irrigationfrom
Rivers & Aquifers
Human distribution
Water for feed growthEvapotranspiration 98% water livestock production
Green Water
Soil moisturefrom
Rainfall
Fixed to land
Water and livestock is complex
Water for livestockeven more complex
Water productivity of livestock productsa. Water productivity of feedsb. Water productivity of animals – inherent + managmentc. Water productivity of animals – feed mix
Local context determin water availabilityd. Climatic pre-conditionse. Local water cycle
Local imporantance of water useda. Human competing demandsb. Environmental impacts
Research solutions Reasearch how to capture system complexity:
Benefits of water uses- Untapped water productivity potential in livestock production- Livestock products vs. Food crops- Nutritional value, not only calories- Non-food benefits - developing vs. developed
Location importance of three water resources- Competing uses- Environmental impacts- Multi-currency perspective, not only water, not only provisioning
Assess local and global synergies and trade-offs to guide investments
