Abstract
This study aims to analyze effects of adoption of motorized water pump on household farm income of smallholder farmers in Mirab Abaya and Arba Minch Zuria Woreda. The total sample size (n=196) was purposively selected from two Woredas and five Kebeles. Descriptive analysis, inferential analysis and Heckman two-stage mode were employed for data analysis. The ordinary least squares (OLS) model result revealed that among the 12 explanatory variables included in the model, four had significant effect on the household annual gross farm income. A unit increase in irrigated land of a household increases annual gross farm income of the households by Birr 6620.9 at 5% significance level. Adoption of motorized water pump has a positive effect on household annual gross farm income. The annual gross farm income of adopter households was higher by Birr 18555.35 than non-adopter households. Market distance and market information is found to influence income and hence well-being, significantly. The results indicated that a 1 km increase in distance of commodity supply market decreases annual gross farm income of farm households by Birr 3992.8 at 1% significance level. Male household heads had obtained significantly higher income compared to female household heads. Key words: Water pump, farm income, T-test, Chi-square, ordinary least squares (OLS), Heckman two-stage.
Highlights
The current government has undertaken various activities to expand irrigation in the country
Ethiopia is believed to have the potential of 3.7 million hectares of land that can be developed for irrigation through pump, gravity, pressure, water harvesting, and other mechanisms (MoFED, 2010)
This study showed that family labor at adult equivalent, irrigable land size, access to irrigation, livestock holding and access to credit are found to have a positive and significant association with household income
Summary
The current government has undertaken various activities to expand irrigation in the country. The evidence from the survey conducted at Central Tigray by Kinfe Asayehegn showed that the ratio of mean income of irrigation users to non-users exceeds by 37.03%. The results further indicate one unit increase in the active labor force of an average household would raise the total income of the household by ETB 3987.14. To this end, keeping other variables constant at their respective mean values, a unit increase in irrigable land of a household increases total income by ETB 23,327.8. Irrigation user households with one hectare irrigable land are better-off in well-being by ETB 23,327.8 than non-user households (Kinfe, 2012)
