河岸侵蚀是孟加拉国常见的危害，对房屋、财产和生计构成重大威胁。近年来，孟加拉国政府加大了努力，通过硬化海岸线，包括建造混凝土护岸，减轻河岸侵蚀，但这些干预措施的当地动态没有得到很好的记录。为了解决这个问题，我们目前的结果，从社区一级的反应，最近在行政区的Ramgati，在孟加拉国下梅克纳河流域建造的2英里长的混凝土护岸的研究。我们的研究结合了定量分析的数据，从住户调查的定性数据，半结构化访谈，以评估居民的看法，新的护岸和景观的河岸侵蚀危害的影响。研究发现，首先，危险意识是普遍的，但可能会受到影响的生计因素有关的动态流离失所和重新安置。其次，我们发现河岸侵蚀的负面影响在空间上是不同的。Ramgati的危险感知受到家庭实际位置的显著影响，那些居住在河流附近和护岸北部和南部未受保护区域的人表示更担心他们将失去家园，并认为这将比远离或现在受堤坝保护的区域的居民更快发生。作为一个基于经验的案例研究，我们的研究结果增加了孟加拉国河岸侵蚀的文献，以及全球类似环境中基于水的灾害的感知研究。
Riverbank erosion is a common hazard in Bangladesh, posing a significant threat to homes, properties, and livelihoods. In recent years, the government of Bangladesh has intensified efforts to mitigate riverbank erosion by hardening shorelines, including the building of concrete revetments, but the local dynamics of these interventions are not well documented. To address this, we present results from a study of community-level response to a 2-mile long concrete revetment recently constructed in the administrative district of Ramgati, in the lower Meghna River basin of Bangladesh. Our study combines quantitative analysis of data from a household survey with qualitative data from semi-structured interviews to assess resident perceptions of the new revetment and its effect on the landscape of riverbank erosion hazard. The study finds, firstly, that hazard awareness is widespread but may be influenced by livelihood factors related to the dynamics of displacement and resettlement. Second, we find that that the negative impacts of riverbank erosion vary spatially. Hazard perception in Ramgati is significantly influenced by the physical location of the household, with those residing closer to the river and in unprotected zones north and south of the revetment expressing much greater worry that they will lose their homes, and believing that this will happen much sooner than residents further away or in the zone now protected by the embankment. As an empirically grounded case study, our findings add to the literature on riverbank erosion in Bangladesh and perception studies focused on water-based hazards in similar settings globally.
