摘      要：Background:Ethiopia is frequently cited as a country that is highly vulnerable to climate variability and *** country’s high vulnerability arises mostly from climate-sensitive agricultural sector that suffers a lot from risks associated with rainfall *** vulnerability factors(exposure,sensitivity,and adaptive capacity)of the agricultural livelihoods to climate variability and change differ across agro-ecological systems(AESs).Therefore,the aim of this study was to analyze AES-specific vulnerability of smallholder farmers to climate variability and change in the Fincha’a *** surveyed 380 respondents from 4 AESs(highland,midland,wetland,and lowland)randomly ***,focus group discussion and key informant interviews were also performed to supplement and substantiate the quantitative *** vulnerability index was employed to analyze the levels of smallholders’agriculture vulnerability to climate variability and *** on socioeconomic and biophysical attribute were collected and combined into the indices and vulnerability score was calculated for each agro-ecological ***:Considerable variation was observed across the agro-ecological systems in profile,indicator,and the three livelihood vulnerability indices-Intergovernmental Panel on Climate Change dimensions(exposure,sensitivity,and adaptive capacity)of *** lowland AES exhibited higher exposure,low adaptive capacity,and high vulnerability,while the midland AES demonstrated lower exposure,higher adaptive capacity,and lower *** wetland and highland AESs scored intermediate ***:Our results suggest that resilience-building adaptation strategies are vital to reduce the vulnerability of smallholder *** measures taken should consider site-specific agro-ecological system requirements to reduce the vulnerability of smallholder mixed crop-livestock agriculture *** the approach based on the long-term rea
