Abstract: The study examines the trend of three main climatic variables (eg. Temperature, Rainfall and Relative humidity) for Rajshahi, Bangladesh by using the time series data for the 1972-2010 period and assesses the relationship between the variables and the yield of three major rice crops (eg. Aus, Aman and Boro). The results of Ordinary Least Squares (OLS) reveal the significant effects of climatic variables on rice yields and these effects vary among the three rice crops. Increase in Temperature and Relative humidity and decrease in Rainfall have both positive and negative effects on the yield. The three climatic variables can explain 23, 91 and 89% of the variance in Aus, Aman and Boro production. The study also evaluates the local knowledge and resource based adaptation techniques adopted by the farmers. Different coping mechanisms like change in transplantation time, cropping pattern change, digging of ponds, selection of short duration species etc are being adopted to minimize the impacts of climatic variations on rice production. Necessity and development of temperature tolerant Aman and Boro rice varieties and farmer’s adaptive strategies are prominent.
