1. Successes in Land Rehabilitation and Management
1. Successes in Land (Cont…)
-Possible to reverse land degradation in Tigray (once was one of the most world’s degraded highlands) through exclosures and physical SWC structures,

1. Successes in Land (Cont…)-Improved land management has become an inherent part of farming systems,
- The ‘More People Less Erosion’ Paradigm (Tiffen et al., 1994) is also valid in Tigray (Between the 1984 and 2011 population increased from 40 to 80 million)

2. Roles of Trees in Reversal of Land Degradation and Management
Trees in combination with SWC structures provide:
- decrease sediment deposition,
- reduce down stream flooding
- reduce sheet and rill erosion
- increase water infiltration- enhance developmentof new springs
2. Roles of Trees in Reversal of Land Degradation and Management (Cont…)
- improve land stabilization
- improve fertility of the soil
- firewood and construction material
- production of grasses
for livestock and
roof building
3. Roles of Livestock in Reversal of Land Degradation and Improved Management
Exclosure: Livestock are forbidden
Cut and Carry Systems are allowed
Cut and Carry livestock feeding
4. Investments in land rehabilitation and improved management
-Free community labour (40 free days/year from each HH) for land rehabilitation)
4. Investments land rehabilitation (Cont…)-Local government and NGO’s involvement (e.g., Food-for-work and Safety Net Programmes)
5. Period of the Land Rehabilitation and Improved Management
- It started after the 1980’s drought but was
with top-down approach
(not effective)
- After the 1990’s, rehabilitation
has become priority agenda in
Tigray (local government in
consultation with community:
In participatory way)
1980’s
1990’s
6. Area covered under the Land Rehabilitation and Improved Management
- Roughly 20 to 30 % of Tigray is rehabilitated.
7. People benefited from Land Rehabilitation and Improved Management
- More than 1 million people have benefited from the land rehabilitation and improved management in Tigray.
8. Data on Land Rehabilitation and Improved Management
Source: Nyssen et al., 2007
More than 83% improved in land rehabiliation as well as land management
Land rehabilitation Land management
10. Main Drivers for Success- Land degradation caused by deforestation and subsequent soil erosion which led to drought and crop failure,

-Extreme weather events (changes in rainfall patterns/ shortage of rain water).

10. Main Drivers for Success (Cont…)-Land resources pushed to their limits, ruptures in fragile equilibrium and contributed the drought of the 1980’s,
-To end the desertification in Tigray, local government and communities fully involved in rehabilitation of degraded lands,
11. Main Obstacles to progress (biophysical, socio-economic and institutional)
-Highly degraded steep slope areas,
-Financial limitation to implement the rehabilitation of the degraded areas,
- Top-down approach during the 1980’s

12. How obstacles overcome (Cont…)
-Socio-economic: 40 days free labor/year and food-for-work (Safety Net Program)
- Community leads land rehabilitation and management
13. Remaining obstacles
-More pressure on existing grazing lands (unprotected lands)
-Increasing demand of firewood and construction material
14. Need for Research or knowledge gap
Biophysical research:
-understanding of seed ecology, functional ecology and seed dispersal
- appropriate and rapid propagation techniques, and
- woodland management
Policy development for:
-sustainable energy consumption
- stall feeding of livestock
-on farm tree planting
16. Potential for scaling up the successes
- Awareness raising: policy makers, researchers, CBO’s
and farmers,
- Experience sharing: best practices
- Full involvement of community
