Summary of Amibara Irrigation Project II Final Report
Project Title: Amibara Irrigation Project II - Pastoralist & Forestry Development Studies
Commissioned by: Water Resources Development Authority, People's Democratic Republic of Ethiopia
Prepared by: MacDonald Agricultural Services Limited, UK
Date: December 1991
1. Introduction
The report examines the impact of irrigation development on Afar pastoralists in Ethiopia's Middle Awash Valley and proposes solutions to mitigate negative effects. The study was commissioned by WRDA with EC funding to address:
- Problems faced by pastoralists due to irrigation expansion
- Ecological restoration needs following irrigation development
2. Key Findings
Environmental Context
- Study area covers 925,450 ha in the East African Rift Valley
- Tropical semi-arid climate with 500mm annual rainfall
- Dominant vegetation is deciduous Acacia bushland
- 22,841 ha currently under irrigated cotton production
Population
Group | Estimated Population |
---|---|
Afar pastoralists | 66,000 (30 clans) |
Non-Afar (State Farm workers, etc.) | 50,500 |
Major Problems Identified
- Loss of grazing land: 23,000 ha of dry season grazing lost to irrigation (40,000 tons annual dry matter production)
- Overgrazing: Concentration of herds on fragile rangelands
- Deforestation: 80,000 tons/year fuelwood demand from State Farm workers
- Environmental degradation: Soil erosion and ecological imbalance
3. Proposed Development Programme
A 10-year Middle Awash Pasture and Forestry Development Programme is proposed with five main components:
3.1 Advance Programme (Phase I)
- Travelling rural health units
- Animal health services
- Primary schools in remote areas
- Domestic water supply development
- Support for Afar settlement schemes
3.2 Pasture and Agricultural Programme
- Small-scale irrigated pasture/farm units (50-100 ha blocks)
- Angelele irrigated pasture limited to 100 ha experimental plot
- Improved management of RRC settlement schemes
- Integrated water supply and range conservation
- Alledeghi Plains development initiative
3.3 Forestry and Tree Planting Programme
- Afar-owned tree plots for firewood production
- Roadside planting within irrigated areas
- Eastern boundary and western perimeter tree belts
- Planting on abandoned saline areas
- Fruit trees and browse around settlements
3.4 Training Programme
Capacity building for Afar in agriculture, forestry, and resource management.
3.5 Institutional Programme
Establishment of management structures to coordinate implementation.
4. Estimated Costs
Component | Birr (million) | US$ equivalent (million) |
---|---|---|
Total Investment Costs | 14.2 | 6.9 |
Total Recurrent Costs | 22.4 | 10.9 |
Total Programme Costs | 36.6 | 17.8 |
5. Key Recommendations
- Adopt small-scale, clan-based approaches rather than large centralized schemes
- Ensure Afar ownership and participation in all initiatives
- Phase implementation over 10 years with mid-term review
- Establish high-level coordination mechanism (suggested under Prime Minister's Office)
- Prioritize confidence-building measures through the Advance Programme
