孟加拉国沿海地区的地形易受灾害影响，气候变化对沿海农业产生了新的抑制作用。本研究的主要目的是探讨气候变化对孟加拉国拉克什米普尔沿海地区农业的影响和不断变化的适应策略。通过实地观察调查、问卷调查和焦点小组讨论等方式收集初步资料。为了进行问卷调查，从拉克什米普尔地区的拉姆加蒂和卡迈勒纳加尔的沿海地区随机抽取了大约120名受访者。整个调查是在2014年3月至2015年2月的季风和冬季进行的。本研究是通过收集第一手资料和二手资料进行的。通过实地观察调查、问卷调查和焦点小组讨论(Focus Group Discussion, FGD)(2014年3月至2015年2月)收集初步资料。问卷采用结构化封闭式问题，通过面对面访谈的方式收集被调查者的信息。二次资料收集自孟加拉国气象局(BMD)。收集到的数据使用SPSS统计软件包(version-16)进行处理和分析，并使用Arc GIS 9.1软件绘制研究区地图。 The results revealed that about 87.5% of respondents have experienced climate change and its impact on their agriculture gradually from 40 years. They also perceived increase in temperature, drought, flood, cyclone and salinity intrusion, rain less winter season, long summer season, unpredictable rainfall, and changing the monsoon respectively. About 96.6 % respondents perceived decrease in rainfall. Results also revealed that about 53% of respondents experienced severe intensity of major climate change induced disasters. Furthermore, 9% respondents experienced little bit severity. Agricultural crops cultivation is changing from previous time due to the climate changing events and decreasing crop production due to their damaging effects. Almost 40% of respondents in the study area were not familiar with coping strategy in response to climate change. They tried to adjust and cope with cultivation of short duration crops, introducing new variety and making embankment.To minimize the effects of climate change short duration crops, new variety and making embankment for crop cultivation need to adopt in study area.
