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. 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. 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

Change: WaterAvailability and Demand Rainfall projected to
haveincreased variability in watersource areas of the Nilebasin;
Greater watermanagement needed. Irrigation water demand willalso
increase in response totemperature increment. Climate extremes
andseasonality are crucial foragriculture productivityFeed

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. 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

EthiopiaImplementation Design - >90% of small scheme
infrastructure performingpoorly, do not consider sub-basin impacts
or the multiple useaspects, which are important to farmers Poor
engineering giving rise to inefficient and expensiveschemes, and no
measuring devices lead to inequitablewater distribution.Governance
and Organisation Lack of co-ordination between institutions
involved inirrigation Capacity is weak Scheme administration and
ownership poor
