Duars is located along the foothills of the Eastern Himalayas with an assemblage of forest cover. It extends from the river Tista in West Bengal to the river Dhunseri in Assam. Within this broad outline, the areal extension between the rivers Tista and Sankosh covering West Bengal is now known as the Bengal Duars or Western Duars and the rest of the portion that lies in the Assam district is named as the Assam Duars or Eastern Duars. In the present study, multi-decadal variability and trends of climatic events (temperature and extreme rainfall) in the Bengal Duars region have been analysed based on long-term dataset (more than 100 years). This region has experienced an increasing trend of temperature. The results show that the average temperature increases by 0.027 degrees year-1 and extreme rainfall becomes 5% higher than earlier since 1975.
