This study estimates the impact of major climate variables
(temperature and rainfall) on crops’ productivity across four
agro-ecological zones of Pakistan. The crops selected were rice, wheat,
maize, cotton and sugarcane. The study used panel data from 1991 to 2010
and applied panel least square techniques. The results revealed that the
effect of climatic variables on crops yield varied across agro climatic
zone due to differences in their climate conditions. Temperature and
rainfall were the important determinants affecting crops productivity
across agro climatic zones of Pakistan. Wheat productivity has been
impacted more in Northern Irrigated Plain-a by average temperature and
in Northern Dry Mountains by rainfall than the other zones. Rice
productivity has been impacted more in Dry Mountains by average
temperature and in the Indus Delta by rainfall than other zones.
Sugarcane productivity has been impacted more by average temperature and
rainfall in Indus Delta than zone IV. Maize productivity has been
impacted more by average temperature and rainfall in Northern Dry
Mountains than other zones. Finally the study recommends proper
mitigative and adaptative strategies to enhance the positive and lessen
the adverse impact of climate change on crops productivity across agro
climatic zones of Pakistan. JEL Classifications: Q15, Q54, Q57 Keywords:
