IRRIGATION AND DRAINAGE PROJECTS

Private concessionaires who operated farms for growing commercial crops such as cotton, sugarcane and horticultural crops started the first formal large scale irrigation schemes in the 1950s in the upper and lower Awash Valley . In the '60s irrigated agriculture was expanded in all parts of the Awash Valley and in the Lower Rift Valley. The Awash valley saw the biggest expansion in view of the water regulation afforded by the construction of the Koka dam and reservoir that regulated flows with benefits of flood control, Hydropower and assured irrigation water supply.

During the Derge era, all private farms were nationalized, thereby ending the highly motivated but embryonic private sector. The government pursued the development of medium and large-scale irrigation schemes as State Farms, initiating a number of schemes dispersed in many parts of the country that ranged from Amibara Irrigation Project in the Middle Awash to Alwero Irrigation Project in Gambella and Gode-West Irrigation near Gode town. Following the downfall of the Dergue, the current government until recently withdrew from expanding State Farms and further construction of medium and large-scale irrigation.

While the development of small-scale irrigation schemes has continued under Regional Water, Mines and Energy Bureaus, the development of medium and large-scale irrigation has virtually ceased since the mid 90s until recently. This is due to the withdrawal of the Federal Government from running state development enterprises such as irrigated state farms, following the adoption of market based economic policy.

The private sector has also been reluctant to fill the gap created by this withdrawal. Private consultancy firms and construction contractors, on the other hand, have quickly emerged with the coming in to force of a market based economic policy. Private irrigation farmers have also commenced operation in the Awash, Meki-zway, and Woito valleys, albeit on a small and medium scale.

The Country has a total area of about 1.13 million km2, with estimated arable land resources of potential of 55 million hectares, or approximately 50% of its land mass (UNDP-FAO, 1984).Despite the huge arable land resources potential, only 14% of the country's total land mass is being utilized for crop cultivation.

CLASSIFICATION OF IRRIGATION PROJECTS

The following criteria are used for classification of irrigation projects in Ethiopia :
Small Scale under 200 ha
Medium scale 200 to 3,000 ha
Large scale Over 3,000 ha

IRRIGATION POTENTIAL

Based upon the various river basin master plans and land and water resources surveys, the aggregate irrigation potentials of Ethiopia have been estimated to be 2,523,000 million hectares, net. The gross irrigation potential would be about 3.7 million hectares.

TOTAL AREA UNDER TRADITIONAL & MODERN IRRIGATION

The total area irrigated till 1991 was 176015 ha, this figure had increased to 197,250 ha in 1998. According to data recently compiled by MOWR 2004/5 from different master plan studies and regions the area under irrigation in the country has increased to about 250,613 ha. This is due to rapid increment of the area under traditional irrigation.
