  3. 3. www.iwmi.orgWater for a food-secure worldNBDC: Developing site-specific RMSinterventions and domains to scale-out1. Understand which RMS is suitable for which location interms of : Bio-physical characteristics Socio-economic situation of the actors(farmer/community) Institutional settings2. Provide tools to the national reserach centres and otherorganisations to provide extension services and NGOs onthe ground the information on site-specific possibleinterventions3. Use these to open dialogue with farmers and communities3
  4. 4. www.iwmi.orgWater for a food-secure worldExample: Improved soil and water conservationon farms, along with small water storage systems,enable farmers to introduce high value enterprises(e.g. Apple) but also replace currently used earlymaturing low-yielding crop varieties with high-yielding ones. This will enable the system toproduce more food, more fodder and income.

  6. 6. NBDC Innovation Platforms: working withcommunities to identify issues and solutionsimportant to them and utilises local indigenousknowledgeThere are prominent local traditional institutionsand these demonstrate that collective action ispossible if initiated by community membersthemselves. Potential for harnessing these.Feed into NationalPlatform and SLM

Irrigation water demand willalso increase in response totemperature increment. Climate extremes andseasonality are crucial foragriculture productivityFeed intoMoWe, MoA,CRGEdevelopment

  10. 10. AWM Technologies: products and practices forsmallholder farmers for agriculture use.AWM Solutions: Any measure (knowledge,policies, markets, and financing) that boosts theuptake of AWM and: Contributes to smallholder livelihoods Benefits women and men and does notincrease income disparities Is cost-effective to implement Can be out-scaled Addresses resource sustainabilityAgricultural Water Management Solutions: Tounderstand the AWM context and where there are investment opportunities thatwill help poor farmers improve their livelihoodswells
  11. 11. Where to prioritize AWM for smallholdersPotential for AWM vary - Where to prioritize AWM forsmallholders ?1) water is available;2) high dependence on water use for agriculture;3) high number of smallholders
