Shrimp aquaculture is the predominant farming practice in the southwest coastal region of Bangladesh and has been under increased pressure from environmental and climatic changes. To date, most of the studies examining farmer's vulnerability and adaption to climate change have been agriculture-focused with little attention to the impacts on other livelihood systems. Based on a case study approach our study presents: i) how local people perceive climate change and whether it corresponds to meteorological records, ii) what climate change impacts people consider significant, and iii) what strategies the shrimp farmers employ to ameliorate perceived risks. This study was conducted using local climate data, focus groups and household survey in Mongla sub-district. This study shows that local people are aware of the changes in hydro-climatic parameters. Their accounts of climate change mostly diverge from the scientific evidence when long-term climate trends are considered, but on short-term variability, the correlation between scientific evidence and local perceptions is high. Repeated adverse impacts caused by climate stressors on livelihood activities shape people's climate risk perceptions. In relation to perceived risks, farmers have made adjustments in their aquaculture practices. Yet, the level of responses clearly lags behind the extent to which concerns about climate disturbances are expressed. This is partly due to farmers' efforts for managing transformation from agricultural livelihood system to aquaculture-based livelihood systems and partly associated with other social factors. This case study recommends governmental support for the shrimp aquaculture sector to facilitate the process of adaptation to changes in the hydro-climatic environment.
