Bangladesh is a country of natural disasters and climatic hazards, which frequently affect its inhabitants’ lives and livelihoods. Among the various risks and disasters, floods are the most frequent hazard that makes haor households vulnerable. Therefore, this study was undertaken to estimate livelihood vulnerability to flooding within the flood-prone haor ecosystem in Bangladesh. Primary data were collected from 100 haor households each from Kishoreganj, Netrokona, and Sunamganj districts (N = 300) by applying a multistage random sampling technique. Data were collected through face-to-face interviews using a pretested structured questionnaire. The Livelihood Vulnerability Index (LVI) and the Intergovernmental Panel on Climate Change (IPCC) framework of vulnerability were applied to compare vulnerabilities among the selected haor-based communities. The empirical results revealed that haor households in Sunamganj district were more vulnerable to flood hazard and natural disaster in terms of food, water, and health than households in the other two districts. Taking into account the major components of the LVI, the IPCC framework of vulnerability indicated that households in Sunamganj district were the most vulnerable due to their lowest adaptive capacity and highest sensitivity and exposure. These findings enable policymakers to formulate and implement effective strategies and programs to minimize vulnerability and enhance resilience by improving the livelihoods of the vulnerable haor households of Bangladesh, especially those in Sunamganj district.

孟加拉国是一个自然灾害和气候灾害的国家，经常影响其居民的生活和生计。在各种风险和灾难中，洪水是最常见的灾害，使住房家庭变得脆弱。因此，本研究旨在估算孟加拉国易发洪灾的生态系统中民生对洪灾的脆弱性。原始数据是从Kishoreganj，Netrokona和Sunamganj地区的100个家庭中收集的（N （= 300）。使用预先测试的结构化问卷通过面对面访谈收集数据。生计脆弱性指数（LVI）和政府间气候变化专门委员会（IPCC）的脆弱性框架，分别适用于比较选择中的漏洞haor为基础的社区。实证结果表明，haor与其他两个地区的家庭相比，Sunamganj地区的家庭在食物，水和健康方面更容易遭受洪水灾害和自然灾害。考虑到LVI的主要组成部分，IPCC脆弱性框架表明，Sunamganj地区的家庭最脆弱，因为它们的适应能力最低，敏感性和暴露程度最高。这些发现使决策者制定和实施有效的战略和方案，以尽量减少脆弱性和通过提高弱势群体的生计，增强抵御haor孟加拉国的家庭，特别是那些在苏纳姆甘杰县。
