Climate Variability and Agricultural Output in Iran (Case Study: Khuzestan Province)

This study examines the Fluctuation climate variability on the production of three main crops (wheat, barley and rice) in Khuzestan province in Iran. A panel data set with 105 observations is used. The results indicated that temperature and rainfall have negative effects on wheat yield. Also, temperature have negative effect and rainfall have positive effect on rice yield and these variables have negative effect on barley yield. On the other hand, changes in climate conditions lead to a decline in the yield of wheat, rice and barley by 0.05%, 0.032%, and 0.021%, respectively. In addition, changes in climate condition in the period 1993-2013 have led to decline in economic profit by 58154.01 thousands Rials for wheat, rice and barley in 2013. Based on the results of research, it is recommended that short-run and long-run weather forecasts to be taken into consideration to prepare and adopt the necessary measures to protect agricultural crops and prevent damage caused by adverse atmospheric and climatic factors in all stages of planting and harvesting. صبر کنید…
