Farmers in the riverine char islands of Bangladesh are frequently affected by climate change due to their proximity to the river and heavy reliance on agriculture for their livelihoods. The present study evaluates char dwellers’ risk perceptions and agricultural adaptations to climate change. Survey data were collected from 98 households, and focus group discussions were conducted using a semi-structured questionnaire from Rydas Bari char under the Gaibandha District of Bangladesh. A standardized risk perception index was created using a four-point Likert scale against sixteen climatic events. In addition, a binary logit model was used to estimate the influence of socioeconomic characteristics of sample households on the decision to choose climate change adaptation strategies. Findings suggest that droughts, river erosion, and floods are the major climatic risks perceived by char dwellers. Additionally, results from a climate vulnerability index portray similar findings that char respondents are more exposed to diverse climatic hazards. The study further investigates local adaptation mechanisms in agriculture with regards to major climatic events. In response to the existing climate change risks, the char inhabitants employ several adaptation strategies in agriculture such as implementing new or alternative farming practices, changing planting times, and cultivating short-duration varieties. The llogit analysis suggests that household age, family size, annual income, farm size, farm ownership and farming experience have a significant influence on farmers' adaptation choices. Household access to education, early warning by extension agents, information on improved agricultural technologies, access to off-farm sources of income and incorporating char people during policy design can effectively enhance farmers’ resilience and help reduce vulnerability.

孟加拉河沿岸的炭烧岛上的农民由于靠近河流，并且严重依赖农业为生，因此经常受到气候变化的影响。本研究评估了炭黑居民的风险感知以及农业对气候变化的适应性。收集了98户家庭的调查数据，并使用Rydas Bari char的半结构问卷进行了焦点小组讨论。在孟加拉国的盖班达区之下。使用四点李克特量表针对十六个气候事件创建了标准的风险感知指数。此外，使用二元logit模型估计样本家庭的社会经济特征对选择气候变化适应策略的决定的影响。研究结果表明，干旱，河流侵蚀和洪水是炭疽病居民感知的主要气候风险。此外，气候脆弱性指数的结果显示出类似的发现，即炭黑的受访者更容易受到多种气候危害的影响。这项研究还针对主要气候事件进一步研究了农业的当地适应机制。为了应对现有的气候变化风险，焦炭居民在农业中采用多种适应策略，例如实施新的或替代的耕作方法，改变播种时间以及培育短时品种。洛吉特分析表明，家庭年龄，家庭规模，年收入，农场规模，农场所有权和耕作经验对农民的适应选择有重要影响。家庭获得教育的机会，推广人员的预警，有关改进农业技术的信息，获得非农收入来源以及在政策设计过程中纳入炭农的做法可以有效地增强农民的适应力，并有助于减少脆弱性。
