Summary of Wolkayite Irrigation Feasibility Report
Introduction
The Wolkayite Irrigation Feasibility and Detail Design Project, conducted by the Federal Democratic Republic of Ethiopia's Ministry of Water Resources, aims to enhance agricultural productivity through irrigation. The project focuses on the Wolkayite area, which has significant potential for irrigated agriculture but faces challenges such as low productivity, traditional farming practices, and limited access to modern inputs.
Project Objectives
- Increase food production to ensure food security.
- Improve the quality of life for rural populations through higher income generation.
- Optimize agricultural production from available land and water resources.
- Alleviate poverty by creating employment opportunities.
Key Findings
Agricultural Status
The Wolkayite area is predominantly rainfed, with low cropping intensity and limited use of modern agricultural inputs. The main crops include sorghum, maize, teff, sesame, and pulses. Livestock farming is also a significant part of the local economy, but it suffers from feed shortages and diseases.
Soil and Climate
The soil in the Wolkayite command area is primarily vertisols, which are clay-rich and require careful management. The climate is characterized by two main agroclimatic zones: Dega (cool) and Kola (hot). The area receives an average annual rainfall of 1114 mm, with most rain falling between June and September.
Proposed Crops and Cropping Patterns
The project proposes two cropping patterns (Option-I and Option-II) with a focus on cereals, oilseeds, pulses, vegetables, fruits, and commercial crops like sugarcane and cotton. The proposed cropping intensity is 170%, with 80% during the rainy season and 70% during the dry season.
Crop Water Requirements
The crop water requirement (CWR) and net irrigation requirement (NIR) were calculated using FAO guidelines. The total NIR for the 27,039 ha command area is estimated at 154.63 million m³ for Option-I and 110.97 million m³ for Option-II. Sugarcane, maize, and vegetables are the most water-intensive crops.
Challenges and Constraints
- Limited access to quality seeds, fertilizers, and agrochemicals.
- Poor drainage and soil management practices.
- Erratic rainfall and natural hazards like drought and floods.
- Inadequate extension services and poor market infrastructure.
Recommendations
- Introduce high-yielding, irrigation-responsive crop varieties.
- Improve soil and water conservation practices.
- Enhance extension services and farmer training programs.
- Develop infrastructure, including roads and storage facilities, to support agricultural marketing.
- Provide financial support and credit facilities to farmers.
Conclusion
The Wolkayite Irrigation Project has the potential to significantly improve agricultural productivity and food security in the region. However, its success depends on the effective implementation of recommended agricultural practices, infrastructure development, and strong institutional support.
