Jeldu Woreda
*West Shewa Zone. Oromia Region, 2500-3200 m amsl, 202, 655 people
![Page 5: Resources-, practices- and community-based rainwater management strategies: Insights from the NBDC sites](https://reader033.fdocuments.us/reader033/viewer/2022061207/5483f8d3b47959e70c8b4abe/html5/thumbnails/5.jpg)
Challenges Opportunities
• Heavy deforestation
• Cultivation on steep
slopes; ~> 80%
• Declining productivity
• Shrinking grasslands
• Acute water shortage
• Inefficient irrigation
• Land conflicts, lease
• Degrading socio-
ecological systems
• Suitable for potato,
vegetable production
• Existing irrigation
cooperatives
• Fair knowledge of SWC
practices
• Good market for inputs,
timber, livestock, milk,
agril. produce
• Good support of EIAR/
HARC, credit , Woreda
institutions

Rainwater Management StrategyIncrease and diversify tree cover, system intensification
including increased storage of
water, transition to new crops/ varieties:
1.Improve cultivation of
Eucalyptus/ other tree species and
control severity of degradation in
uplands. 2. Intensification of agriculture and
livestock in the mid-and
lowlands ; efficient diversion and use of stream
water for high value agriculture
in the valley bottoms.
3. Learn from the experience of Melka village
community for benefit sharing,
impact, outscaling.

Diga Woreda
*East Wollega Zone. Oromia Region, 1380-2300 m amsl, 68,906 people
![Page 8: Resources-, practices- and community-based rainwater management strategies: Insights from the NBDC sites](https://reader033.fdocuments.us/reader033/viewer/2022061207/5483f8d3b47959e70c8b4abe/html5/thumbnails/8.jpg)
Challenges Opportunities
• Continued clearing of forest areas.
• Shrinking grasslands, animal diseases
• Inefficient irrigation schemes.
• Midland- lowland divide.
• Acute poverty/land shortage among the new settlers
• Inefficient markets, poor connectivity.
• Suitable for mango, maize, coffee, oilseeds, vegetable production
• Opportunity for rearing livestock for meat and poultry.
• Good knowledge of NRM, and tree cultivation.
• Innovations and expertise of Harar settlers.
• High quality lowlands for off-season intensification.
• Good connectivity in progress.

Rainwater Management StrategyMaintain/increase forest
cover and environmental
services, increase
productivity of trees, coffee
and livestock, and ability to access new markets:
1.Improve orchard and plantation establishment,
management and rejuvenation of old orchards.
2. Intensification of agriculture,
coffee and livestock in the
mid-and lowlands ; improve
performance of diversion schemes.
3. Engage with and learn from the
experiences of Maddejalala settlement
community for innovation, impact and out-scaling.

Fogera* Woreda
*South Gondar Zone. Amhara Region, 2500-3200 m amsl, 202, 655 people
![Page 11: Resources-, practices- and community-based rainwater management strategies: Insights from the NBDC sites](https://reader033.fdocuments.us/reader033/viewer/2022061207/5483f8d3b47959e70c8b4abe/html5/thumbnails/11.jpg)
Challenges Opportunities
• Highly degraded and stony uplands.
• Too-much too-little water syndrome.
• Acute feed shortage for dairy and livestock.
• Groundwater/ stream water too costly to pump.
• Water sharing conflicts • Brokers, private
lenders, land rentals
• Good opportunity for rice, pulses, vegetable production.
• Khat- an established and emerging cash crop.
• Ready market for dairy, livestock products; inputs
• Good support from Woreda admin, University, donors
• Scope for off-farm income sources.

Rainwater Management StrategyIncrease tree
cover and fodder
availability, water storage
and productivity, increase area
under off-season
irrigation; better use of
residual moisture.
1. Upland catchment
management with emphasis to retire highly degraded lands to trees of
economic/ nutrition value.
2. Enhanced water storage for critical
in-season/ off-season irrigation, efficient use of limited off-season water for
high-value agriculture in the lowlands. Rooftop
RWH.3. Make good use of
highly organized Awaramba
community and progressive farmers
for validation, impact and out
scaling .( http://www.youtube.com/watch?v=vJzuiAIMFio&NR=1
