Our collaboration with GWP
Alain VidalCPWF Director
GWP 2011 Consulting Partners Meeting : Water as a catalyst for achieving food security
Stockholm, 18-19 August 2011
CPWF aims to increase the resilience of social and ecological systems through better water management for food production
Through its broad partnerships, it conducts research that leads to impact on the poor and to policy change
Addressing critical development challenges in 6 river basins
Dams and poverty reduction
Benefit-sharing mechanisms
Landscape approach to rainwater management
Integrated managementof rainwater for
smallholders
Water governance andmanagement in coastal areas

Key collaborations with GWPLongstanding exchange of views and informationGWP - a strategic partner in African basins Helping set the research agenda, and influencing changes in
knowledge, attitudes and practices among policymakers Limpopo: partner of the ‘coordination and change’ project led
by FANRPAN – emphasis on policy Volta: partner of the ‘coordination and change’ project led by
VBA – emphasis on communications Nile: under development Involved in cross-cutting science activities, eg resilience of
social & ecological systems
Food security research & actionSpecific proposals
Intermediary between science and policy Helping set the research agenda Facilitating processes to influence water-related policy Focusing on the water-food-energy nexus?
Need for joint learning to understand the science and turn it into strategic messages to engage policy makersEvolve GWP concept of IWRM and CA concept of trade-offs From sharing water (zero-sum) … …to sharing benefits (win-win)
Sharing the benefits
Restoring ecosystem services in the Andes
Downstream – where the concern for ecosystem services emerged
8
Eutrophication and shrinking of
Fuquene Lake (downstream)
High altitude wetland (paramo)
degraded by potato cropping and overgrazing
Restoring upstream and downstream ecosystem services
9
Paramo restored through
conservation tillage and oat/potato
rotation
Water quality and downstream ecosystem services from Fuquene
Lake improved
Understanding resulting changes on upstream water

Annual net income:US$ 2,183/ha
Annual net income:US$ 1,870/ha
Conservation agriculture and paramo restoration supported by revolving fund
Farmers‘ insufficient gain and risk aversion: only 11% converted
Revolving fund credit: +180 farmers /year
Potato cropping, grazing pressure, degradation of paramo
What are the challenges?Sharing the benefits from water How do we estimate them? How can ecosystem services support enhance food
security? How do ecosystem services work in larger basins?
Which partners & disciplines are required?More ideas later today…
