2. Humanitys greatest challenge To feed 9 billion people in2050, we need to produce70% more food and raisenutrition levels withoutdestroying the environment Rising demands are alreadycontributing to: Water scarcity Land degradation Loss of ecosystemservicesWater for a food-secure worldwww.iwmi.org 3. Global Demography, GDP and Water Withdrawals 1900 - 2000 Population increase about 3.6 times Water withdrawals increased 6.8 times GDP increased 19 times , about 3% per year (constant prices, IMF) Water for a food-secure world www.iwmi.org 4.

Sanitation Water Food Challenge in India About 128 million septic tanks andlatrines in India contribute to 80%of the pollution of Indias surfacewaters due to the lack of septagetreatment facilities. Inadequate sanitation costs IndiaRs. 2.4 trillion (US$ 53.8 million)per year or 6.4 percent of Indias2006 GDP. 12. Food safety and health at risk Can we turn a threat into an opportunity? 13. The ChallengeIt is not so muchthat water isscarcebut more about howit is managed andaccessed by themost vulnerableWater for a food-secure worldwww.iwmi.org 14. Looking forward .. some reasons foroptimism? Photo: Prue Loney/IWMI Water for a food-secure world www.iwmi.org 15. Food security and water scarcity We can produce enough food for 9 billion it isabout access to food and improved nutrition Feeding more people is not simply a question ofbio-physical innovation Water is as much a social issue as a physicalone and therefore we have to look to governanceand institutional solutions A critical aspect is scaling up R&D outcomes Water for a food-secure world www.iwmi.org 16.

Sustainable intensification the comingchallenge across many scales Closing the actual vs potential yield gap (on farmissue) Twice the yield off half the area? (on-farm issue) Capitalizing on natural infrastructure (nationalpolicy issue) Recognizing the value of ecosystem services(river basin/regional level issue) The water-food-energy-environment nexus(national-transboundary issue)Water for a food-secure worldwww.iwmi.org 19. Reasons for optimism #1: Upscaling the recoveryof groundwater tables and reduced electricityusageThe problem in GujaratFree electricity encouragedgroundwater overuseResulted in groundwateroverdraft Safe Semi-critical Critical Over exploited Saline 20. Jyotigram in Gujarat, India Issue was over-pumpingof groundwater becauseof subsidized electricity Pragmatic solutionsuggested by IWMI andpartners was separationof electricity supply tovillages and pumps Outcome was reducedelectricity use, lessgroundwater use,improved power supply Similar schemes now proceeding into domestic usersneighboring statesWater for a food-secure worldwww.iwmi.org 21. Jyotigram: technical solutionsSeparate reliable power feeds for farm and non-farm useGives villages 24 hour metered, three-phase power supply fordomestic uses, in schools, hospitals, village industriesTargets high-quality power supply on 30-50 days of peak irrigationdemandSupports on-farm storage, rewards groundwater recharge,subsidizes drip-irrigation 22. Result in GujaratHalved subsidy to agricultureReduced groundwater overdraftIncreased yieldsSpurred rural non-farm enterprisesNow rolling out in other states 23. Reasons for optimism #2: Ground Water Policy change Agricultural growth in WestBengal had slumped by morethan half Research identified that a majorobstacle to agriculturalproductivity was getting accessto groundwater New policies recommended byIWMI were adopted to reducered-tape and improvegroundwater access forsmallholder farmers. The policy change could benefitmore than 5.6 millionsmallholdersWater for a food-secure worldwww.iwmi.org 24. Why did we think of groundwater based solution for Bengal?Groundwater use status in IndiaHighGW potential Only 42% of its potential is usedand less than 10% blocks are critical, none are over-exploited 80% of farmers depend on GW Water for a food-secure world www.iwmi.org 25. Reasons for optimism #3: Renewedcommitment to irrigated agriculture Most countries are committed to revitalizeirrigation systems In Asia Modernization Capacity Building Policy Reforms underway In Africa, Investments in expansion Rehabilitation PPP ModelsWater for a food-secure worldwww.iwmi.org 26. Realities of meeting future demand Limited new cultivable areas 80 - 90% of increased production will come fromexisting cultivated area higher yield per ha, double or triple cropping installation of irrigation and/or drainage systems in areas withouta system modernization of existing irrigation and drainage systems installation of drainage in irrigated areas installation of irrigation in rainfed areas with drainage 10 - 20% from land reclamationWater for a food-secure worldwww.iwmi.org 27. Why Irrigate? Area per capita isdecreasing Approximately 20%irrigated It produces 45% ofcereals Irrigation increasesyield by about 300%per unit of landWater for a food-secure worldwww.iwmi.org 28. Reasons for optimism #4: Revitalizingsurface irrigation in areas ofgroundwater over- exploitation Water for a food-secure world www.iwmi.org 29. Surface Storage and Conjunctive Use to Minimize PowerSubsidies and Carbon Footprint of IrrigationDeep groundwaterareas are where largecanal systems operate 75-80 b kWh of power valued at US $ 9.0 billion/year used for groundwater pumping Surface storages and conjunctive use can reduce power and carbon footprintWater for a food-secure worldwww.iwmi.org 30. E.g. new approaches to rehabilitate and adapt For example, encourage distributed storage to improve system flexibility and reliability e.g. Rajasthan: farm-storages; Gujarat, Tamilnadu, Andhra Pradesh: village tanks replenished by canal water Modernize irrigation systems e.g. pressurized systems Water for a food-secure world www.iwmi.org 31. Reasons for optimism #5: Re-visit Participatory Irrigation ManagementSome results from research: Small sized schemes serving lesser number of farmers(lower transaction costs) Schemes with simple distribution systems (easy tooperate) Non-paddy systems where accurate water control is veryimportant Schemes producing high value crops (higher capacity offarmers to pay for professional help) Systems that have been rehabilitated before transfer In India, PIM succeeded where NGOs were involvedWater for a food-secure worldwww.iwmi.org 32.

Indicators of success that were considered for creating a composite success score Outcome indicators (7) ISF collection; financial viability; maintenance; equity; reliability and adequacy; participation and reduction in disputes Impact indicators (2) Crop related (production, yields, cropping intensity) Livelihoods related (poverty, wages, employment) Water for a food-secure world www.iwmi.org 34. Reasons for optimism #6: Environmental Flows initial steps on the Ganga Iconic river lots of cultural and religious angles never explored before Expert Panel approach 10 different specialists representing various disciplines. Firsttime in India - large capacity building component Endorsed by newly formed National Ganga River Basin Authority and input to futureBasin plans RBMP). 35. Reasons for optimism #7: Policy influence - the exampleof Urban Agriculture and Safe Wastewater Use inGhanaIWMI research results directly or indirectly influenced thesestrategies and policies: Food & Agriculture Sector Development Policy II (2007) Strategic Agenda for Urban & Peri-urban Agriculture (2008) Ghana Buffer Zone Policy (2008) Agriculture Sector Investment Plan 2009-2015 Ministry of Food and Agriculture MTP 2009-2013 Vision statement on Urban and Peri-urban Agriculture (Accra) National Environmental Sanitation Strategy and Action Plan (NESSAP) (2010) -input provided- Accra Agricultural Bye-law revision (still in progress) National Irrigation Policy, Strategy, and Regulations (2011) Water for a food-secure world www.iwmi.org 36. Wastewater ReuseCan we develop effective businessmodels that promote safe recyclingand reuse?Courtesy Pay DrechselWater for a food-secure worldwww.iwmi.org 37. Farm based options for risk Drip and furrow irrigationreduction Sedimentation ponds Cessation of irrigation Filter Limited soil splash Improved water fetching Increased retention time On-farm treatment ponds Water for a food-secure worldwww.iwmi.org 38. SolutionsAssessing risks, developing and applying low-cost options for risk reduction in line with WHO and FAO Guidelines. 39. Opportunities for urban poor Urban demand for perishablevegetables is very high. Urban horticulture can beeffectively promoted throughintensified (vertical) urbanfarming and business modelsfor waste resource recovery.
