Abstract
Local contexts as well as levels of exposure play a substantial role in defining a community's perception of climate and environmental vulnerabilities. In order to assess a community's adaptation strategies, understanding of how different groups in that community comprehend climate change is crucial. Public risk perception is important as it can induce or confine political, economic, and social actions dealing with particular hazards. Climate change adaptation is a well-established policy discourse in Bangladesh that has made its people more or less aware of it. Similarly, shrimp-farming communities in southwestern Bangladesh understand environmental and climate change in their own ways. In order to understand how the shrimp-farming communities in coastal Bangladesh perceive current climate instabilities, we conducted a qualitative study in shrimp-farming villages in coastal Bangladesh where about 80% of commercial shrimp of the country is cultivated. We compared farmers' perceptions of local climate change with existing scientific knowledge and found remarkable similarities. Our assessment shows that at least two factors are critical for this outcome: coastal people's exposure to and experience of frequent climate extremes; and a radical approach to defining climate regimes in Bangladesh by various stakeholders and the media, depicting anthropogenic global warming as a certainty for the country. Thus, a convergence of scientific construct and sociocultural construct construes the level of awareness of the general public about climate change.Entities:

Shrimp-farming community’s perception of climate change.
| Parameter/Phenomenon | Aquaculturists’ Perception (a) | Scientific Data (Trend) (b) |
|---|---|---|
| Summer temperature | Increased heavily. | Average maximum temperature increased by 0.05 °C/year. |
| Winter temperature | Overall increased slightly with bitter cold waves for few days. | Mean December temperature increased by 0.23 °C /decade. |
| Monsoon rainfall | No change, delayed. | Rainfall increased by 2.24mm/year. 3 |
| Winter rainfall | Decreased, virtually no rain. | No significant change. 4 |
| Frequency of cyclones or storms | No change. | Increased in the second half of the 20th century. 5 |
| Severity of cyclones or storms | Increased slightly. | Increasing trend. 6 |
| Flood | Occasionally by storm surges, severe (Aila, Sidr). | 25% increase in the number of major floods over the last 100 years. 7 |
| Salinity ingression | Heavily increased. | About 6,000 ha of new land affected every year. 8 |
| Sea-level increase | About 0.5 m within last 15 years in nearby rivers. | About 4-5 mm/year in the west coast. 9 |
| Drought | No or very few droughts in the locality. | Increasing trend in northern Bangladesh. 10 |
