| Abstract: | In this study, the impacts of climate variables on the mean and variability in Aus variety rice yield in Bangladesh are assessed. Using the theoretical framework of the Just–Pope production function, cross‐sectional time series data on Aus rice yield and maximum temperature, minimum temperature and rainfall at a district level over a period of 38 years are analysed for evidence of rice yield variability as a result of climate change. The findings reveal that minimum temperature and rainfall decrease Aus yield variability. However, maximum temperature appears to increase variability, which may reduce Aus rice production. Therefore, government should create an enabling environment to develop temperature‐tolerant rice varieties for Aus rice crop to ensure ongoing food security. |
