Coastal area of India is more prone to the devastating impact of climate change. The present study was conducted in Sunderban coastal ecosystem of West Bengal which is famous for mangrove forest and aquatic resources but this area is now under the adverse impact of climate change. Total six villages were studied from the two blocks of South 24 Pargana district of West Bengal for the present research study. It was observed that nearly 38 per cent of the respondents had heard about climate change. Most of respondents perceived climate change due to rapid industrialization by human being. People were more aware about the phenomena like increase in temperature, reduction in agricultural and livestock production, increase diseases, increase sea level etc. than the phenomena like frequent cyclone, occurance of cold wave, heavy fog and precipitation. The mean score on the awareness about perceived consequences due to climate change was very high on item – ‘reduction in agricultural production’ followed by ‘there will be a large scale migration or exodus of people and animals from Sunderban’. Increase in diseases due to climate change was the major perceived risk by the respondents in agriculture, animal husbandry, fishery and human health sector. Major risks related to forestry and biodiversity included decrease in forest area and reduction in certain plant, animal and bird species. Increase in poverty was the major perceived risk under socioeconomic and cultural life by the respondents
