CPWF Overview March 2011

  1. 1. CPWF HighlightsLearning how to conduct integrated R4D Alain Vidal, Director Larry Harrington, Research Director
  2. 2. Global food crisis:a poverty “countdown”3 billion poor below US$2.5/day2 billion suffer from malnutrition1 billion suffer from hunger 75% of them are rural poor Alleviating hunger means reducing rural povertyReducing rural poverty Increase the income of the rural poor to enable food security and investment into productivity Ensure they can cope with short-term and long-term changes
  3. 3. The resilience challenge Food production communities and ecosystems should be able to cope with local and global changes (climate, economy, demography, migrations…), ie become more resilient  Achieved through improved water productivity (more food with less water) together with empowerment, equity, market access, health and ecosystem services3
  4. 4. 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 change4
  5. 5. CPWF Basins in phases 1 and 2 2 1
  6. 6. Lessons learnt from Phase 1 Restoring ecosystem services in the Andes
  7. 7. Downstream – where the concernfor ecosystem services emerged High altitude wetland (paramo) degraded by potato cropping and overgrazing Eutrophication and shrinking of Fuquene Lake (downstream)
  8. 8. Restoring upstream anddownstream ecosystem services Water quality and downstream ecosystem services from Fuquene Paramo restored Lake improved throughconservation tillage and oat/potato 8 rotation
  9. 9. Understanding resulting changeson upstream water 60 58 56 54 Conservation agriculture More water stored, 52 % volumetric water % Volumetric Water 50 restoring the buffer Traditional 48 agriculture role of paramo 46 44 42 40 Better soil 38 porosity, filtration, i 36 ncreased carbon 1 Horizon 2Accumulated Organic 0.20 storage Conservation Matter (g/g) 0.15 agriculture AOM (g/g) Traditional 0.10 agriculture 0.05 0.00 1 2 3 4 9 Size fraction RT-Horizon 1 CT-Horizon 1 RT-Horizon 2 CT-Horizon 2

Understanding triggers for change between alternate resilient states Annual net income: Conservation US$ 2,183/ha agriculture and paramo restoration Revolving fund credit: Farmers‘ supported by +180 farmers /year insufficient gain and risk revolving fund aversion: only 11% converted Potato S cropping, grazing pressure, degradation of paramo Annual net income: US$ 1,870/ha10
  11. 11. CPWF Phase 2 (2009-2014)What it takes to do problem-solving and integrated research for development in 6 river basins
  12. 12. Focusing the CPWF strategy Focus on priority “basin development challenges” or BDCs in specific parts of six basins Use all scientific tools needed to address the challenge, emphasizing those with the greatest potential for development impact within the 15 year CPWF time frame Investment in each BDC research program: USD 5-6m distributed across 4-5 strongly inter-linked projects Further integration into CRP5 12
  13. 13. Six basin development challenges(highly abbreviated versions) Andes – Benefit-sharing mechanisms Ganges – Floods and salt in the Delta Limpopo – Small reservoirs, rainwater and livelihoods Mekong – Dams and livelihoods Nile – Rainwater management in Ethiopia Volta – Small reservoirs, rainwater and livelihoods
  14. 14. BDC research programs Coherent strategy focused on problem-solving Integration of policy, institutional, governance, access, and technical innovations Spatial targeting of innovations Cross-scale analysis of downstream consequences, including for ecosystem services Engagement with senior policymaker, other stakeholders, communications, gender, capacity-building Functional links among projects (output from one project used as input by another project)14
  15. 15. An example of a BDC research program– the Ganges – the challenge Water, water everywhere, all year round, but farm families barely subsist on a single low-yield rainy season rice crop per year . . . Because of water scarcity Post-rainy season water outside of polders becomes too saline15
  16. 16. An example of a BDC research program– the Ganges – the vision Store more fresh season water within polders Use for high value post-rainy season crops and aquaculture Change in sluice gate management to let water in when it is fresh, but keep it out when it is saline16
  17. 17. An example of a BDC research program– the Ganges - projects Water governance: who gets how much water, when, and for what purposes – and who gets to decide (sluice gate management) On-farm water management: getting the most value out of scarce stored fresh water Spatial targeting, which strategies for which polders External consequences and global drivers, downstream consequences of success, likely effects of global drivers Coordination and change: policy engagement, communications, CB, impact pathways17
