Abstract: In this paper, we have examined the effect of climate variables on the yield average and variability of major grain crops (rice, maize, and wheat) in Iran from 1983 to 2014. For this purpose, we made use of the Just and Pope Production Function crop yields panel data. The results revealed that the influences of climate variables were different in the crops. The time trend positively influenced the average crop yield and yield variability, but increasing in the maximum temperature had a negative impact on the grain yields. While the maximum temperature increased the risk of wheat production, this variable reduced the risk of maize and rice production. Minimum temperature and rainfall had positive influences on the average yields of the crops. Furthermore, minimum temperature decreased the production risk of maize and wheat. Finally, the influences of rainfall on the yield variability were positive for whole crops. Regional dummies were statistically significant for certain climate zones. It is expected that future climate changes reduce the mean yield of the crops, all the more showing the significance of crop insurance schemes and policies that mitigate insecurity of food in the light of expected climate variations in the coming years.
