Climate change poses a significant threat to the sustainability of agricultural production among smallholder farm households in Ethiopia. To reduce the adverse effects of climate risks, farm households have sought to adopt different adaptation strategies. This study investigates factors influencing farm households' choice of climate adaptation strategies and associated effects on their food security in Ethiopia using data collected from 516 farm households from three regions. A multivariate probit and propensity score matching models were used to analyze data. Major adaptation strategies adopted by the farm households in the study area are planting drought-tolerant crop varieties (60%), changing the planting dates (53%), growing diversified crops (49%), and diversifying the sources of household income (45%). Results suggest that older farm household heads are more likely to use drought-tolerant crop varieties to reduce climate risks. Farm households with larger farmland size and those with more years of experience in farming are more likely to use drought-tolerant crop varieties and crop diversification strategies. Farm households with larger family size are more likely to use crop and income diversification strategies and change the planting dates against the backdrop of a high risk of climatic shocks. Membership in input supply cooperatives, frequency of contact with extension agents, and access to information on expected rainfall and temperature are positively associated with different adaptation practices adopted by farm households. Farm households who have adopted climate adaptation strategies have higher food security status (by 2.3-2.8%) compared to those who have not. Thus, the farm households' climate adaptation practices have positive food security effects in Ethiopia.
