Opportunities (examples): Better management of rainwater Sharing of resources, not just waterInnovative ways for people to work together.

Main points

Agriculture is a huge water user, and a huge opportunity

2 - 5 litres

daily

20 – 500 litres

daily500 – 3000 litres

per kg2000 l/day - vegetarian diet5000 l/day - grainfed meat diet

Opportunity: better management of rainwater

Upgrading rainfed systems

Rainwater management has a high potential for increasing livelihood resilience through crops, fisheries and livestock

Page 9: Widespread recognition of water scarcity threat, especially in agriculture …but much can be done

Opportunity: sharing of benefits from water

Page 10: Widespread recognition of water scarcity threat, especially in agriculture …but much can be done

Win-win situations are rare in water. Need to share.

Sharing goes beyond WATER sharing, to assigning water to higher value uses, and sharing the BENEFITS with those who give up water.

Example: urban-based trust funds invest in upland farming practices

Sharing: Locally

Page 11: Widespread recognition of water scarcity threat, especially in agriculture …but much can be done

Local adaptation to climate change

Page 12: Widespread recognition of water scarcity threat, especially in agriculture …but much can be done

“Sharing” at present is export of food from water rich to water scarce countries. Only about 6% of agricultural water use involved

Climate change to 2070 is predicted to increase cereal production in temperate latitudes, while reducing it in tropical latitudes

Total food production likely to be sufficient until 2070. How will it be shared?

Sharing: International

Opportunity: ways of working together

Formulaic solutions have limited applicability

Past success is no guarantee of future success

Expertise can help but is not sufficient; relationships are key

Uncertainty of outcome remains

New ways of working

Page 16: Widespread recognition of water scarcity threat, especially in agriculture …but much can be done

Diversity of people increases innovation

Page 17: Widespread recognition of water scarcity threat, especially in agriculture …but much can be done

“Complex multi-sector problems need new ways of working: The really important issues facing society … cannot be tackled by any organization acting alone” Huxham and Vangen, 2005

“While hierarchies are not vanishing, profound changes in the nature of technology, demographics, and the global economy are giving rise to powerful new models of production based on community, collaboration, and self-organization rather than on hierarchy and control.”Tapscott and Williams, 2006.
