The objective of the research is to examine dairy production technology adoption impact onrnrural household food security and identify factors affecting adoption in Ethiopia evidence fromrnBasona Worena woreda, Amhara regional state. A multistage sampling procedure wasrnemployed to draw 283 sample households from one woreda and two kebeles. The kebeles werernselected in random sampling procedure and within the kebeles sample household were groupedrnin two strata (adopters and non-adopters). To analyze the data both descriptive and inferentialrnstatistics were employed to characterize and analyze dairy technology adoption and foodrnsecurity of the households. Food consumption score and household dietary diversity scoresrnwere employed to examine the food security status of the sample households. The statisticalrnmodels namely, binary logistic regression, Tobit and propensity score matching were used torndetermine factors affecting the decision of farm households who participate (adopt) dairyrntechnologies, extents of dairy technology adoption and impact of technology adoption onrnhousehold food security respectively. The descriptive result indicated that dairy technologyrnadopters were food secured as compared to non-adopter households in terms of foodrnconsumption score. The dietary diversity results also indicate that there is a significant meanrndifference between two group in main food group. The binary logit result revealed that,rnfrequency of extension service, membership of milk collection center and input access positivelyrnaffect the adoption decision. While age of the household head negatively affects the decision tornadopt. The result from propensity score matching indicated that dairy technology adoption hasrnpositive impact on household food security. The impact of dairy technology adoption onrnhousehold food security in terms of food consumption score has an effect on the householdrnfrequency of food consumption per week. Similarly, the dietary diversity of the household has anrneffect on the intake of diversified food in 24-hour recall on the household food security. usingrnkernel, nearest neighbor and radius respectively. Finally, the average treatment effect onrntreated (ATT) reveled that, the dairy technology adoption has increased the household foodrnconsumption score and dietary diversity by 23.19% and 13.7% respectively. The studyrnconcludes that dairy technology adoption has remarkable effect on the household food securityrnstatus. Based on the finding of this study it is recommended that, improving farmers awarenessrnand perception trough training, strengthen developmental agents capacity, introducing andrndisseminating and different improved variety dairy technologies with reasonable cost,rncontinuous follow-up, improvement in input supply, and interventions that deal constraintsrnrelated to dairy technology adoption.
