导读：气候变化和相关的极端事件对数百万小农赖以生存的农业生产产生了负面影响。埃塞俄比亚的雨养农业系统正变得越来越容易受到气候变化的影响。在选择适当和有效的气候变化适应办法时，确定一个系统脆弱性程度的差异是很重要的。为此，本研究采用生计脆弱性指数（LVI）和生计脆弱性指数-政府间气候变化专门委员会（LVI- ipcc）方法，考察了古拉格不同农业生态区农户生计对气候变率和变化的脆弱性。使用混合参与式方法从三个农业生态区的357个样本家庭的代表中收集数据。结果：虽然各农业生态区各成分相对价值存在差异，但总体LVI表明，位于低地农业生态区的Sodo woreda （District）更容易受到气候变率和变化的影响。本研究发现，脆弱性差异可归因于家庭特征的差异、基础设施的缺乏、生计多样化程度低以及可用技术的缺乏。结论：因此，本研究呼吁利益相关方准备因地制宜的干预措施，以降低小农对气候变率和变化的脆弱性，增强农户的适应能力。
Introduction: Climate change and related extreme events are negatively affecting agricultural production where millions of smallholder farmers depend up on it. Ethiopian rain-fed agriculture system is becoming more vulnerable to the impacts of climate change. Identification of difference in the level of vulnerability of a system is important in selecting appropriate and effective adaption options to climate change. Thus, this study examined the vulnerability of farm household's livelihood to climate variability and change in different agroecological zones of Gurage Zone using the Livelihood Vulnerability Index (LVI) and Livelihood Vulnerability Index-Intergovernmental Panel on Climate Change (LVI-IPCC) methods. Data were collected from a representative of 357 sample households across three agroecological zones using a mixture of participatory methods.Results: Results suggested that although there was difference in components relative value across agroecological zones, the overall LVI indicate that Sodo woreda (District) which is found in the lowland agroecological zone was more vulnerable to climate variability and change. This study found that vulnerability differences were attributable to variations in household characteristics, lack of access to infrastructure, low level of livelihood diversification, and lack of available technologies.Conclusions: Therefore, this study calls for stakeholders to prepare context-specific intervention to reduce smallholder farmer's vulnerability to climate variability and change and strengthen the adaptive capacity of farm households.
