Our collaboration with GWP by Alain Vidal, CPWF Director - CP meeting 2011 Day 2

  1. 1. Our collaboration with GWP<br />Alain Vidal<br />CPWF Director<br />GWP 2011 Consulting Partners Meeting : <br />Water as a catalyst for achieving food security<br />Stockholm, 18-19 August 2011<br />
  2. 2. CPWF aims to increase the resilience of social and ecological systems through better water management for food production<br />Through its broad partnerships, it conducts research that leads to impact on the poor and to policy change <br />
  3. 3. Addressing critical development challenges in 6 river basins<br />Water governance and<br />management in coastal areas<br />Integrated management<br />of rainwater and small reservoirs<br />Landscape approach <br />to rainwater management<br />Dams and poverty reduction <br />Benefit-sharing mechanisms<br />Integrated management<br />of rainwater for smallholders<br />2<br />1<br />
  4. 4.
  5. 5. Key collaborations with GWP<br />Longstanding exchange of views and information<br />GWP - a strategic partner in African basins<br />Helping set the research agenda, and influencing changes in knowledge, attitudes and practices among policymakers<br />Limpopo: partner of the ‘coordination and change’ project led by FANRPAN – emphasis on policy<br />Volta: partner of the ‘coordination and change’ project led by VBA – emphasis on communications<br />Nile: under development<br />Involved in cross-cutting science activities, eg resilience of social & ecological systems <br />
  6. 6. Food security research & actionSpecific proposals <br />Intermediary between science and policy<br />Helping set the research agenda<br />Facilitating processes to influence water-related policy<br />Focusing on the water-food-energy nexus?<br />Need for joint learning to understand the science and turn it into strategic messages to engage policy makers<br />Evolve GWP concept of IWRM and CA concept of trade-offs<br />From sharing water (zero-sum) …<br />…to sharing benefits (win-win)<br />
  7. 7. Sharing the benefits<br />Restoring ecosystem services in the Andes<br />
  8. 8. Downstream – where the concern for ecosystem services emerged<br />8<br />High altitude wetland (paramo) degraded by potato cropping and overgrazing <br />Eutrophication and shrinking of Fuquene Lake (downstream)<br />
  9. 9. Restoring upstream and downstream ecosystem services <br />9<br />Paramo restored through conservation tillage and oat/potato rotation <br />Water quality and downstream ecosystem services from Fuquene Lake improved <br />
  10. 10. Understanding resulting changes on upstream water<br />10<br />Conservation <br />agriculture<br />More water stored, restoring the buffer role of paramo<br />Traditional <br />agriculture<br />% Volumetric Water<br />Better soil porosity, filtration, increased carbon storage<br />Conservation <br />agriculture<br />Accumulated Organic Matter (g/g)<br />Traditional <br />agriculture<br />
  11. 11. Understanding triggers for change between alternate resilient states<br />11<br />Conservation agriculture and paramo restoration supported by revolving fund <br />Annual net income:<br />US$ 2,183/ha<br />Farmers‘ insufficient gain and risk aversion: only 11% converted<br />Revolving fund credit: <br />+180 farmers /year<br />Potato cropping, grazing pressure, degradation of paramo<br />S<br />Annual net income:<br />US$ 1,870/ha<br />
  12. 12. What are the challenges?<br />Sharing the benefits from water<br />How do we estimate them?<br />How can ecosystem services support enhance food security?<br />How do ecosystem services work in larger basins?<br />Which partners & disciplines are required?<br />More ideas later today…<br />12<br />
