Impact of small-scale irrigation on the livelihood and resilience of smallholder farmers against climate change stresses: Evidence from Kersa district, eastern Oromia, Ethiopia

This study mainly aimed to evaluate the impact of small-scale irrigation on the livelihood and resilience of farmers toward climate change in Kersa district of the eastern Oromia region of Ethiopia. A sample of 288 randomly selected households (158 non-adopters and 130 adopters) was used to gather the data. The data were analyzed using the resilience capacity index and propensity score matching methods. The resilience capacity index was utilized to summarize all the resilience indicators into a single value, and propensity score matching was used to evaluate the impact. The results of the average treatment effect on the treated analysis revealed that adopters were better-off in crop yields by 84.72 quintals per hectare, 55641.60 birr in total income, and by 2.02 resilience capacity index compared to non-adopters. The results of the study indicate that small-scale irrigation significantly improves farm households' livelihoods and mitigates the effects of climate change by enhancing their ability to respond to erratic weather events, which builds their resilience. Therefore, policymakers should prioritize small-scale irrigation practices to improve rural households' livelihoods and farmers’ resilience in areas with irregular rainfall and a high risk of drought.
