Water scarcity limits food production

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
