In topographically diverse highland terrain, socio-economic and environmental conditions can vary dramatically over relatively short distances. This presents a challenge for climate resilient development strategies, as exposure to climate variability and change, climate impacts, and adaptive capacity differ between communities located within common cultural and administrative units. The Livelihood Vulnerability Index (LVI) framed within the United Nations Intergovernmental Panel on Climate Change (IPCC) vulnerability framework (LVI-IPCC) offers a tool to assess climate vulnerability through direct household surveys. This makes it particularly appropriate for analyses at sub-community and community scales. Here we apply the LVI-IPCC to communities of Choke Mountain, located in the Blue Nile Highlands of Ethiopia. Recognizing the physiographic and climatic diversity that exists in this mountainous environment, we implement LVI-IPCC analysis for 793 mixed crop-livestock farming households using the five distinct agroecological systems (AES) that compose the populated area of Choke Mountain as a framework for analysis. For each AES, an LVI index, adaptive capacity metric, and LVI-IPCC vulnerability score was calculated. We found that each of these metrics varied systematically across AES. High elevation sloping lands and low elevation steep lands exhibited relatively low adaptive capacity and high vulnerability while midland AES had higher capacity and lower vulnerability. These results suggest that resilience building interventions for Choke Mountain ecosystems should be targeted to address the specific circumstances of each AES. The approach of applying LVI-IPCC at AES scale could be applicable to other climate vulnerable mountainous regions.

农业生态系统特定的气候脆弱性分析：生计脆弱性指数在热带高地地区的应用。

在地形多样的高原地区，相对较短的距离，社会经济和环境条件可能会发生巨大变化。这给应对气候变化的发展战略提出了挑战，因为位于共同文化和行政单位内的各社区在气候变化和变化，气候影响和适应能力方面的差异很大。联合国政府间气候变化专门委员会（IPCC）脆弱性框架（LVI-IPCC）框架内的民生脆弱性指数（LVI）提供了一种通过直接家庭调查评估气候脆弱性的工具。这使其特别适合于亚社区和社区规模的分析。在这里，我们将LVI-IPCC应用于位于埃塞俄比亚青尼罗河高地的扼流山社区。认识到此山区环境中存在的自然地理和气候多样性，我们使用构成Ch牛山人口稠密地区的五个独特的农业生态系统（AES），对793个混合农牧业家庭实施LVI-IPCC分析。对于每个AES，都计算了LVI指数，自适应容量指标和LVI-IPCC漏洞评分。我们发现，每个指标在AES上都有系统的变化。高海拔坡地和低海拔陡坡地表现出相对较低的适应能力和较高的脆弱性，而中部陆上AES具有较高的能力和较低的脆弱性。这些结果表明，应对扼流山生态系统的抵御能力建设干预措施应针对每个AES的具体情况。
