Prepared by: TAMS (New York) and ULG Consultants Ltd (Warwick, U.K.)
Date: May 1997
Commissioned by: Ministry of Water Resources, Federal Democratic Republic of Ethiopia
1. Overview
The document presents a comprehensive master plan for the integrated development of the Baro-Akobo River Basin in Ethiopia, covering natural resources assessment including:
- Land evaluation
- Soils and soil conservation
- Geology
- Mineral resources
2. Key Annexes
Annex 2A: Land Evaluation
Provides detailed analysis of land resources including:
- Land use/cover mapping (40% open woodland)
- Land suitability classification (FAO framework)
- Population Support Capacity model
- Irrigation potential assessment (14,231 km² suitable)
Land Capability Class | Area (km²) | Recommended Use |
---|---|---|
Annual/perennial crops | 36,000-9,705 | 60.20% of basin |
Perennial crops/grazing | 9,350 | 12.32% |
Forestry | 2,683 | 3.56% |
Annex 2B: Soils and Soil Conservation
Key findings on soil erosion and conservation:
- Identified critical erosion areas needing immediate attention
- Proposed land husbandry approach integrating conservation with farming systems
- Soil loss measurements showing up to 278 t/ha/year in some areas
Annex 2C: Geology
Geological characterization of the basin:
- Pre-Cambrian basement rocks in eastern uplands
- Tertiary lavas and Quaternary sediments in western lowlands
- Low seismic activity in the basin
Annex 2D: Mineral Resources
Identified mineral potential including:
- Gold (primary and placer deposits)
- Platinum
- Nickel, base metals, chromite, iron
- Three mineralized belts: Asosa-Benshangul, Metti-Nejo, and Akobo
3. Development Priorities
The plan identifies key development priorities:
- Soil conservation measures for erosion control
- Irrigation development (16% highly suitable land)
- Mineral resource development, particularly gold
- Watershed protection and rehabilitation
4. Implementation Recommendations
The report recommends:
- Detailed surveys for priority projects
- Improved geological mapping (more colors/symbols)
- Land register establishment
- Farmer participation in conservation programs
