Vulnerability of smallholder farmers to climate variability and change across different agro-ecological Zones in Oromo Nationality Administration (ONA), North east Ethiopia

Ethiopia is frequently identified as a country that is highly vulnerable to climate variability and change. The study was aimed to examine agro-ecological based smallholder farmers' livelihood vulnerability to climate variability and change in Oromo Nationality Administration (ONA), North East Ethiopia. Data were collected from a survey of 335 sampled households, focus group discussion, and interview from three different agro-ecologies in the study area and secondary sources. Count, percentage, mean, standard deviation, Chi-square test (test of independence), ANOVA, Livelihood Vulnerability Index (LVI) and LVI-IPCC were used for analysis. LVI and LVI-IPCC results revealed that Kolla is the most vulnerable (0.18) because of its highest exposure (0.74) and sensitivity (0.71) values and lowest adaptive capacity (0.49) while Daga is least vulnerable (0.08) because of its lowest exposure (0.61) and sensitivity (0.42). Overall, results suggest that the two methods resulted in similar degrees of vulnerability and identified Kolla agro-ecological zone as the most vulnerable while the Dega agro-ecological zone is the least vulnerable of the three agro-ecological zones. The researchers conclude that development strategies and plans should be prepared considering local-specific issues and/or situation.
