Information on the consequences of discouraging growing eucalyptus on farm is insufficient. The study aims at investigating the effect of growing eucalyptusin the livelihood of smallholder farmers to attain food security. The study was conducted close to Jimma, Southwestern Ethiopia. Information on household characteristics and growing eucalyptus were collected through interview. Two kinds of analysis wereused for data analysis. Independent t testing for differences between households and paired t testing for differences within households. The survey result showed about 54.8% of the household owned a land less than lha. Only about 87.6% households were capable to feed family up to eleven months from what they produce. About 44.9% of the households owned eucalyptus. The frequency distribution result showed that the annual income of the majority of both coffee and eucalyptus grower households were more than 4000. Could there have not been income from eucalyptus, this frequency distribution had been shifted to annual income between 2000 and 3000 Ethiopian birr. An independent t testing result showed the average annual income of coffee and eucalyptus grower household was significantly different from only coffee grower household, (p = 0.003). The paired t testing result shows that there could be significant difference in annual income within coffee and eucalyptus grower households (t = 7.441, df = 34, p =0.000). Growing eucalyptus is the most important livelihood part of poor and medium households. Discouraging eucalyptus may increase vulnerability to food insecurity at household level. 收起
