Introduction: Climate change has emerged as a major threat to Bangladesh. Higher and fluctuating temperatures and changes in rainfall caused by climate change and extreme weather events have reduced crop production. A better understanding of the local dimensions of vulnerability is therefore essential to develop appropriate adaptation measures that can alleviate these adverse impacts. Purpose and methods: The main purpose of this study was to identify the determinants of Aman rice farmers’ choice of adaptation strategies to climate change and weather in Khulna district, Bangladesh. About 100 farm households susceptible to salinity intrusion, extreme temperatures and drought were surveyed, and these data were supplemented by major climate data of the district for 65 years (1948–2013). A binary logistic regression was then utilized to estimate the factors that influence households’ choice of adaptation strategies. Results and Conclusions: About 97% of farmers perceived that the climate had changed over the past 30 years while only 3% did not. Further, 97% believed that rainfall had decreased and reduced rice production, yet the data show this not to be the case with a significant increase in rainfall observed in the area in the study period. About 89% of farmers have undertaken some form(s) of adaptation and they were further asked about their main adaptation type. Family size, annual income, farmer-to-farmer extension and access to subsidies have a positive and significant impact on rice farmers’ adaptation strategies to climate and weather change effects. Farm size and credit access had a negative and significant impact on adaptation. Four variables: age, education, household assets and occupation were not statistically significant in explaining adaption strategies. The chief adaptation strategies of farmers are cultivation of salinity-tolerant rice, rice variety switching, replanting of rice, changing planting dates, conversion of rice paddy to fish production and use of different crop varieties in alternate years.

影响孟加拉国稻农适应气候变化策略和极端天气事件影响的因素

简介：气候变化已成为对孟加拉国的主要威胁。由于气候变化和极端天气事件引起的温度升高和波动以及降雨的变化，使农作物减产。因此，更好地了解脆弱性的局部范围对于制定适当的适应措施以减轻这些不利影响至关重要。目的和方法：这项研究的主要目的是确定孟加拉国Khulna区阿曼稻农选择适应气候变化和天气的策略的决定因素。对大约100个易受盐分入侵，极端温度和干旱影响的农户进行了调查，这些数据得到了该地区65年（1948年至2013年）主要气候数据的补充。然后利用二元逻辑回归分析来估计影响家庭选择适应策略的因素。结果与结论：大约97％的农民认为过去30年中气候发生了变化，而只有3％的农民没有意识到。此外，有97％的人认为降雨减少并减少了稻谷产量，但数据表明，在研究期间该地区观测到的降雨没有明显增加，情况并非如此。大约89％的农民已经采取了某种形式的适应措施，并进一步询问了他们的主要适应类型。家庭规模，年收入，农民向农民的扩展以及获得补贴的方式，对稻农适应气候和天气变化影响的战略产生了积极而重大的影响。农场规模和信贷渠道对适应产生了负面和重大影响。四个变量：年龄，教育程度，家庭资产和职业在解释适应策略上没有统计学意义。农民的主要适应战略是耐盐水稻的种植，水稻品种的转换，水稻的重新种植，播种日期的改变，稻田向鱼类生产的转化以及隔年使用不同作物品种。
