Rural riverine households in Bangladesh are confronted with many climate-driven hazards, including riverbank erosion, which results in loss of productive land and other natural resources of the riverine households, and thus threatens their livelihoods and food security. This study assesses the main drivers of vulnerability and livelihood cycle of vulnerable riparian households in Bangladesh. The study utilises the IPCC framework of vulnerability and develops a weighted approach by employing the livelihood vulnerability index and the climate vulnerability index. The results reveal that the livelihood vulnerability index and the climate vulnerability index differ across locations, however, a high index value for both measures indicates the households' high livelihood vulnerability to climate change and hazards. The main drivers that influence the vulnerability dimensions are livelihood strategies and access to food, water and health facilities. These hazard-prone households are also vulnerable due to their existing low livelihood status that leads to a vicious cycle of poverty. The findings of this study are crucial for policymakers to formulate and implement effective strategies and programs to minimise vulnerability and to enhance the local adaptation processes in order to improve such households' livelihood across Bangladesh.
孟加拉国农村河岸地区的家庭面临着许多由气候引发的灾害,包括河岸侵蚀,这导致河岸家庭的生产性土地和其他自然资源丧失,从而威胁到他们的生计和粮食安全。本研究评估了孟加拉国脆弱河岸家庭脆弱性和生计周期的主要驱动因素。该研究采用了政府间气候变化专门委员会(IPCC)的脆弱性框架,并通过运用生计脆弱性指数和气候脆弱性指数制定了一种加权方法。结果表明,生计脆弱性指数和气候脆弱性指数因地点而异,然而,这两项指标的高指数值都表明家庭对气候变化和灾害的生计脆弱性较高。影响脆弱性维度的主要驱动因素是生计策略以及获得食物、水和卫生设施的机会。这些易受灾家庭由于其现有的低生计状况而变得脆弱,这导致了贫困的恶性循环。本研究的结果对于政策制定者制定和实施有效的战略及计划至关重要,这些战略和计划旨在将脆弱性降至最低,并加强地方适应进程,以改善孟加拉国此类家庭的生计。
