CPWF 10 years of R4D for water & food security ANU

  1. 1. 10 years of research for developmentto improve water & food security of the rural poorAlain Vidal, DirectorCGIAR Challenge Program on Water and Food
  2. 2. NigerWater, food and poverty analyzed in 10 basins1.5 billion people50% of the poorest < 1.25US$/day
  3. 3. Water, water, everywhere,Nor any drop to drink
  4. 4. Not just population increase Not just scarcity-10,000010,00020,00030,00040,00050,000-500 0 500 1000 1500 2000 2500GNI($/capPPP)Water availability (m3/cap)GNI vs WaterDrivers for poverty
  5. 5. Problems are more nuanced thatscarcity alone
  6. 6. Water productivityremains very low over most areasWP (estimated potential / typically 1-2 kg/m3)VoltaLimpopoNileNigerGangesIndusYRMekong
  7. 7. There is enough water to meet ourneeds, it’s how we manage it !Sustainable intensification Beyond a focus on productivity Income and ecosystem servicesEquitable sharing of benefitsfrom water Finding balanced solutionsInstitutional water management A holistic approach to avoid fragmentation among actorsAddressed through basin-focused research programsaddressing a major development issue in each basinGuiding investment to relevant pro-poor interventions
  8. 8. Policy dialogues, stakeholdersengagement, outcomes and impactResearch… evidence-basedto deeply understand problems development challenges ofrelevance to those living in a basinand target interventions or solutions… “innovations”, “interventions”, “strategies” or “alternatives”through engagement and learning processes…where stakeholder behavior is influenced and outcomesachieved Engaged and informed stakeholders themselves choose to changepractice because they perceive as to their own advantage

  11. 11. Sustainable fisheries and hydropowerin the Mekong river basin
  12. 12. The Mekong water – fish – energynexusMassive hydropower potentialFisheries provide 50-80% ofanimal protein to 60 millionpeople and 50% of ruralincomeFisheries and food securitythreatened by thediscontinuities due to largehydropower damsMRC, 2010
  13. 13. Changes in practice sharing the benefitsbetween fisheries and energy productionWater management techniquesand practices improving thebenefits of riparian communitiesRice-fish systems (THPC, Laos)Cassava (Yali Falls,Vietnam)Artificial wetlands(THPC, Laos)
  14. 14. Improved water control:an opportunity for the poor of theGanges Delta ?
  15. 15. Among world’s poorestBBS / WorldBank / WFP (2009)Poverty, food insecurity, vulnerability 75% of households (HH) with 0.2-0.6 ha HH income US$700/year 80% of population below national poverty lineToo much water in rainy seasonSalinity and lack of fresh water indry season
  16. 16. Untapped potential but growingpressure from salinityHuge potential toimprove foodsecurity andlivelihoodsSalinity not aconstrainteverywhere – evenan opportunity ifwater properlycontrolledSoil salinityNoneVery slightSlightStrongVery strong
  17. 17. Sustainable intensification of polders:technical and institutional challengesLots of viablecropping systemspossible with cropdiversification,fish and shrimpBut it’s all about water control !Need for political changes at national and local levelsCanal maintenance and managementShifting from rice monocultureRice ShrimpUpper threshold limit of salinity - RiceDateWatersalinity(ppt)Lower threshold limit of salinity - ShrimpDaily water salinity
  18. 18. How do such interventionsincrease water and food security ?Enhanced resilience Combined technical and institutionalinnovations prevent systems frommoving to undesired state when shockedWater and food security Looking beyond the « yield gap » enables diversify foodproduction (crops, fish and livestock) and ecosystem services Additional income alleviates povertyEmpowerment Enhanced people’s rights and institutional governance
