Dabus Irrigation Project - Progress Report No. 1 (November 1980)
Project Overview
The Dabus Irrigation Project is a feasibility study conducted by Halcrow-ULG Limited under contract with UNDP/FAO for the Valleys Agricultural Development Authority in Ethiopia. This first progress report covers work carried out between mid-September and end of November 1980.
Key Findings
- Three main arable soils identified with different crop potentials
- Significant hydropower potential identified on the Dabus River
- Dabus Swamp shows potential for regulation with a low earth dam
- Survey work delayed due to logistical challenges
Project Components
Agricultural Findings
| Soil Type | Recommended Crops | Potential Area |
|---|---|---|
| Red clays | Grapes for raisin production | 500 ha |
| Intermediate grey soils | Red peppers for olio-resin extraction, onions for dehydration, ginger | 2,500 ha |
| Heavier grey soils | Sugar or cotton (for local consumption) | To be determined |
Engineering Studies
- Identified 8 potential pumping station sites (down from 12)
- Hydropower potential confirmed at site identified by USBR in 1964
- Dabus Swamp could provide significant storage with a 3-4m earth dam
- Survey work significantly delayed due to tall grass and lack of bulldozer
Social Development
- Population consists mainly of Arabic-speaking migrants from Sudan and indigenous Fakumkum people
- Peasant Associations exist but have limited function
- Generally positive attitudes toward project, though understanding is limited
Environmental Studies
Initial findings suggest the project could bring net environmental benefits if handled carefully. A draft report has been prepared.
Challenges
- Logistical difficulties: Poor access, tall grass, delayed construction of camp facilities
- Communication problems: Radio equipment stuck in customs, reliance on telegrams
- Survey delays: Only 25% of sample areas surveyed by end November
- High costs: Irrigation and transportation costs are significant concerns
Next Steps
- Complete remaining soil survey observations (94% already done)
- Finalize land evaluation and prepare maps/reports
- Continue analysis of cropping options and irrigation systems
- Complete detailed topographic and geotechnical studies
- Address survey delays with improved clearing methods
Conclusion
Despite logistical challenges, most aspects of the study are progressing as planned, except for topographic surveys which are about one month behind schedule. The project area shows good potential for various irrigated crops, particularly on red and intermediate soils, with additional benefits possible from hydropower development.
