  3. 3. Andes • Ganges • Limpopo • Mekong • Nile • Volta Context (1) Water rights and water access at the catchment level Water governance Payment for environmental services Broader water-related policy issues Crop-aquaculture systems CPWF1 + BFP: emerging themes Rainwater harvesting and rainwater management Crop-livestock systems and livestock water productivity Multiple-use systems at the community level Integrated land and water management Small reservoirs and other small water infrastructure in dryland areas Wastewater management for peri-urban food systems
  4. 4. Andes • Ganges • Limpopo • Mekong • Nile • Volta Context (2) through (specific) Basin Development Challenges and - establishing basin-level programs - promoting an integrated research, innovations and impact strategy - creating Topic Working Groups to ensure knowledge sharing Towards CPWF2: main outputs… To demonstrate ways to alleviate poverty by increasing farmers income To identify ways to enhance resilience to change driven by external forces in

  8. 8. Andes • Ganges • Limpopo • Mekong • Nile • Volta Building on past experience Objectives (1)
  9. 9. Andes • Ganges • Limpopo • Mekong • Nile • Volta • The context – small reservoirs (small, numerous, scattered, network…) – multiple users for multiple uses (diversity, co-occurrence,…) – quantities and qualities of water (requirements, impacts,…) – conflicts (management, governance,…) • The expectations – The V3 project will develop integrated management options to enhance productivity & ensure equitable allocation of water resources. – It will identify uses and users, assess their needs, clarify social and ecological determinants, control health consequences. – For individual small reservoirs considered within their biophysical contexts and their economical dynamics. Objectives (2)
  10. 10. Andes • Ganges • Limpopo • Mekong • Nile • Volta Uses require water (quantity and quality) Uses impact the resource (quantity and quality) There exist trade-off between impacts and requirements That determine the nature of available resources Water Uses and Users Requirements Resources Impacts Key words Integrated managements Processes studies Local scale Objectives (3)

  13. 13. Andes • Ganges • Limpopo • Mekong • Nile • Volta Integrated management aim at several objectives: – Perpetuating infrastructures – Protecting / improving water quality for various uses – Reaching / enhancing water productivity potentials – Seeking for equity Objectives that need Knowledge on processes in their contexts – (e.g.) diachronic analyses (temporal evolution) – (e.g.) synchronic analyses (spatial diversity) – (e.g.) prospective analyses – … Objectives (6)
  14. 14.

  30. 30. Andes • Ganges • Limpopo • Mekong • Nile • Volta Lessons (1) Interactions with other Vi projects - existing with V4 and V5 - nearly zero with V1 and V2 Interactions within V3 - no “team spirit” (not a crew but an assemblage of interests) - Boura as exception? (forthcoming synthesis)
  31. 31. Andes • Ganges • Limpopo • Mekong • Nile • Volta Lessons (2) V3 design - too complex (lack of integrative framework/model for the aggregation of pluridisciplinary results collected) - too ambitious (lack of time) VA animation - not enough (absence of cross-fertilization) - not adapted (proactivity in an adaptive management context)
  32. 32. Andes • Ganges • Limpopo • Mekong • Nile • Volta Lessons (3) Delivery of results - communication before validation (ethics/impact) CPWF pressure - understandable (from research: ‘Outcome Logic Models’ …) - but excessive (… toward extension: ‘Impact Pathways’)

  34. 34. Andes • Ganges • Limpopo • Mekong • Nile • Volta ‘‘The challenge lies not merely in reducing vulnerability [against Climate Change] but also in getting the structures in place so governments and investors can tackle adaptation in the most effective manner possible. The good news is we can improve lives today while building the crucial infrastructure needed for tomorrow.’’ Recommendations (1) Source: ‘‘Global Warming and Adaptability’’ Wall Street Journal, 12 Dec. 2011
