LVI for disaster and CC.

This study aims to assess the livelihood vulnerability to climate change of ethnic minority communities in Yen Bai province, a typical mountainous region in northern Vietnam. Utilizing the Livelihood Vulnerability Index (LVI) framework developed by Hahn et al. (2009), in combination with the IPCC vulnerability structure, the research analyzes eight components related to household characteristics, health, food, water, housing and productive land, social and financial networks, livelihood strategies, and exposure to climate shocks. Data were collected through a combination of desk study and survey with 480 households from two major ethnic groups: Tay and Thai.The results indicate that the Thai group has a higher overall LVI score (0.43) compared to the Tay group (0.37), reflecting greater livelihood vulnerability. The main factors contributing to this difference are limited livelihood diversification, lower educational attainment, weaker access to healthcare, and higher dependency on climate-sensitive resources. Although both groups are highly exposed to climate-related hazards such as flash floods, landslides, and droughts, the Thai group demonstrates greater sensitivity and lower adaptive capacity. This research contributes theoretically by adapting and refining the LVI framework to suit the context of upland ethnic communities, and practically by providing empirical evidence to inform climate adaptation policies. The study highlights the need for differentiated and context-specific strategies that prioritize ethnic minority communities with high vulnerability, focusing on improving education, livelihood diversification, healthcare access, and institutional support mechanisms.本研究旨在评估越南北部典型山区省份安沛省（Yen Bai）的少数民族社区所面临的气候变化生计脆弱性。本研究采用Hahn等人（2009）提出的生计脆弱性指数（Livelihood Vulnerability Index, LVI）框架，并结合政府间气候变化专门委员会（Intergovernmental Panel on Climate Change, IPCC）的脆弱性分析架构，对与家庭特征、健康状况、食品保障、水资源、住房与生产用地、社会与金融网络、生计策略以及气候冲击暴露度相关的八项维度展开分析。研究通过案头调研与问卷调查相结合的方式，从岱依族（Tay）与泰族（Thai）两大少数民族群体的480户家庭中收集数据。研究结果显示，泰族群体的整体生计脆弱性指数得分（0.43）高于岱依族群体（0.37），反映出前者生计脆弱性更高。造成这一差异的主要因素包括生计多元化程度有限、受教育水平偏低、医疗服务可及性较弱，以及对气候敏感型资源的依赖度更高。尽管两大群体均高度暴露于山洪、滑坡与干旱等气候相关灾害，但泰族群体表现出更强的气候敏感性与更低的适应能力。本研究在理论层面通过适配并优化生计脆弱性指数框架以贴合山地少数民族社区的研究场景，在实践层面则通过提供实证依据为气候适应政策制定提供参考。本研究强调，需制定差异化且贴合本地情境的策略，优先关注高脆弱性的少数民族社区，重点聚焦于提升教育水平、推动生计多元化、改善医疗服务可及性以及完善制度支持机制。
