Agricultural and aquaculture transformation in southwest coastal Bangladesh: environmental change impacts and adaptive capacity

Climatic, salinity, cropping area, cost-benefit data were collected from primary and secondary sources. I collected secondary data from government agencies, websites and published materials. I collected primary data on farmers perception of climatic change, risks, adaptation, drivers of intensification, yield, price and cost-benefit from the study villages in southwest coastal Bangladesh. Multiple data collection activities such as focus group discussion, household case study, household questionnaire survey, key informant interviews were applied to collect primary data. Data were processed and analysed using statistical software (e.g. excel, R, @Risk). The collected data supported to answer the research questions. All data set were used to justify the viability of crop and aquaculture systems in salinity affected southwest coastal Bangladesh.本研究从一手与二手渠道收集了气候、盐度、种植面积及成本收益相关数据。其中二手数据来源于政府机构、公开网站及已发表的文献资料；一手数据则采集自孟加拉国西南沿海的调研村落，内容涵盖农户对气候变化、相关风险、气候适应措施、农业集约化驱动因素、作物产量、产品价格与成本收益的认知情况。本次一手数据采集采用了焦点小组讨论、农户个案研究、家庭问卷调研及关键知情人访谈等多种调研方法。所收集的数据均通过统计软件（如Excel、R、@Risk）完成处理与分析。所获数据可用于回应本研究的核心研究问题，全部数据集均用于验证孟加拉国西南沿海受盐度影响区域的作物种植与水产养殖系统的可行性。
