Abstract
In spite of the significant contribution of small scale irr igation towards food supply and
employment creation there are enormous factors that challenge efficiency as well as their
effectiveness.
The purpose of this study is to identify major constrai nts for the effectiveness of existing small
scale irri gation schemes based on Batu Oegaga Communal Small Scale Irri gation in the upper
A wash valley.
The study employed both qualitative and quantitative methods of data generati ng and analysis
techniques.
In the study it was found that 57. 1 % of the targeted area is not totally irrigated because of
deficiencies in planning and designing that didn't take into account the topography and pump
capacity to deliver sufficient water.
Binary logistic was applied together wi th descriptive methods to analyze the survey data in
identi fy ing and measuring household level determinants of effectiveness of small scale
irrigation schemes. The model categorized improved irrigators and not improved irrigators due
to the irrigation project in 86% of the cases correctl y. Out of the 16 hypothesized variables ten
of them increased the probability of improvement of household 's li vi ng standard after irrigation
as expected. Four of the variables including number of oxen possessed by famil ies and level of
output from rain fed production are found stat isticall y significant. Proper planning and
designing of small scale irri gation is paramount. Emphasis has to be given for land preparation.
Provision of credit service for purchase of inputs and covering expenses related to irrigation
practice are areas of intervention.
