Bilate River Basin Study: Analysis of Socio-Economic Aspects
Introduction
The Bilate River Basin covers approximately 5,650 km² across 10 Woredas in Ethiopia, with a population of about one million. The study examines socio-economic implications of proposed irrigation development, focusing on existing state farms (Bilate-Abaya and Bilate Tobacco Farms) and potential expansion.
Key Findings:
- Current irrigated area: 2,553 ha (of 3,023 ha net area)
- Estimated irrigation potential: 25,000 ha
- Previous studies found inadequate for definitive conclusions
Social Aspects
The basin is densely populated (177 persons/km² vs national average of 35/km²) with high population density in surrounding areas limiting resettlement options.
Population Statistics:
Metric | Value |
---|---|
Total basin population | ~1 million |
Boyo Swamp population | 24,000 (5,600 families) |
Average family size | 4.3 persons |
State Farm Operations
Bilate-Abaya Farm
- Under Ministry of State Farm Development hierarchy
- Chronic financial losses (Birr 1.44-3.22 million annually)
- High costs (36-52% farm overhead) and low productivity
- Labor shortages despite area's high population density
Bilate Tobacco Farm
- Managed by Ethiopia Tobacco and Matches Corporation
- Better facilities but similar research deficiencies
- Estimated economic loss: Birr 360/ha (1984/85)
Development Alternatives Analysis
Three Main Alternatives:
- Full development with Boyo Dam (9,723 ha, Birr 96.8M cost)
- Rehabilitation + expansion with Boyo Dam (7,723 ha, Birr 74M)
- Rehabilitation + expansion with Dendo Dam (7,723 ha, Birr 75.3M)
Key Findings:
- All alternatives show negative financial viability
- Boyo Dam would displace 2,500 families (23,000 people)
- Estimated annual meat production loss: 3.15M kg (Birr 3.15M)
- Rehabilitation alone shows 26.55% financial return
Recommendations
- Prioritize rehabilitation of existing farms (high return)
- Improve farm management and reduce overhead costs
- Address labor issues through better facilities
- Conduct more research on crop varieties and practices
- Consider social impacts of Boyo Dam carefully
