Abstract

This study examines the past weather impacts on boro rice cultivation in Bangladesh including physical input variables to explore the impacts of weather. A cross-sectional time series dataset over 44 years consisting climate variables, non-climatic factors, and boro rice yield across seven climatic zones of the country is used for the present study. Employing a panel data regression model, findings reveal that average temperature reduces boro yield growth whereas seasonal rainfall improves it. All the physical input variables have positive and significant impacts on boro cultivation. However, the contribution of non-climatic factors is much higher than that of climate variables. Finally, physical inputs should get emphasized to include crop-climate model to estimate the exact impact of climate change on boro yield growth.
