Abstract

This paper tries to estimates the impact of climate variability/change on the rice productivity of Assam. For the study purpose we use the time series data (1970-2010) for the respective variables of the study. While we have taken yearly average temperature and yearly average rainfall as a climate variable, where these two variable are also the independent variable of the study along with area of rice cultivation in hectare, area covered by HYV (High Yielding Varieties) seeds in hectare, area covered by irrigation facility in hectare, fertilizer consumption in kg per hectare and average area of land holding in hectare. We used the Cob-Douglas production function in the form of log-log model and the multiple regression counterparts for the analysis, the Cob-Douglas production function technique is the most appropriate for the agricultural sector research. Here it shows, climate as a production input for the agricultural crop productivity. The estimated result shows that the increasing temperature has a negative impact on the productivity of the major crop rice and rainfall has a positive impact on the productivity of this crop in Assam.

Keywords: climate change, agriculture, rice, productivity
