Irrigation development is a policy priority for the Laka Tana basin. However available baseflow can irrigate less than 3% of area. The irrigated area can be increased from water stored in constructed reservoirs, pumping water from Lake Tana and by using groundwater. While groundwater has the grea...

Evaluating irrigation technologies to improve crop and water productivity of onion in Dangishta watershed during the dry monsoon phase
Long term use of Maresha plow, a conventional plow pulled by oxen, has resulted in the formation of a restrictive layer thereby limiting water movement and aeration as well as root zone penetration in the soil profile. Several studies have shown that improved tillage practices can positively affe...

Application of deep tillage and Berken Maresha for hardpan sites to improve infiltration and crop productivity [Abstract only]
Intensification of rainfed agriculture in the Ethiopian highlands has resulted in soil degradation and hardpan formation, which has reduced rooting depth, decreased deep percolation, and increased direct runoff and sediment transport. The main objective of this study was to assess the potential i...

Center pivot and linear move irrigation systems’ design and operation are primarily limited by soil infiltration rates. Boom systems have been suggested to improve infiltration and decrease runoff by reducing the instantaneous water application rate of center pivots and linear move systems. In th...

Irrigation has a large potential to increase agricultural output and yield per unit area. However, the long term sustainability increased production, together with degradation of the soils (and associated water bodies) in irrigated areas may be irreparably damaged by inappropriate watering schedu...

Center pivot and linear move irrigation systems’ design and operation are primarily limited by soil infiltration rates. Surface runoff can be a problem on some soils whose in-take rates are low. Additional design and management factors must be considered to prevent runoff in these systems. Boom s...

Smallholder irrigation expansion would signi cantly increase agricultural production, and reduce food insecurity and poverty levels in East Africa. This paper reviews literature on trends, constraints and opportunities of smallholder irrigation in four East African countries: Ethiopia, Kenya, Tan...

A review of trends, constraints and opportunities of smallholder irrigation in East Africa
The Ethiopian government has declared the Lake Tana - Beles region to be a growth corridor and irrigation development is one of the priorities. Since the dry season river flow is limited, groundwater has the greatest potential for increasing irrigation in the near future. The main drawback is lac...
