This study estimates the impact of major climate variables(temperature and rainfall) on crops’ productivity across fouragro-ecological zones of Pakistan. The crops selected were rice, wheat,maize, cotton and sugarcane. The study used panel data from 1991 to 2010and applied panel least square techniques. The results revealed that theeffect of climatic variables on crops yield varied across agro climaticzone due to differences in their climate conditions. Temperature andrainfall were the important determinants affecting crops productivityacross agro climatic zones of Pakistan. Wheat productivity has beenimpacted more in Northern Irrigated Plain-a by average temperature andin Northern Dry Mountains by rainfall than the other zones. Riceproductivity has been impacted more in Dry Mountains by averagetemperature and in the Indus Delta by rainfall than other zones.Sugarcane productivity has been impacted more by average temperature andrainfall in Indus Delta than zone IV. Maize productivity has beenimpacted more by average temperature and rainfall in Northern DryMountains than other zones. Finally the study recommends propermitigative and adaptative strategies to enhance the positive and lessenthe adverse impact of climate change on crops productivity across agroclimatic zones of Pakistan.
