1 CLIMATE CHANGE IMPACT ON CROP PRODUCTIVITY IN KHYBER PAKHTUNKHWA (Thirty Years Analysis i.e. 1981-2010) Samreen Babar 1 , Prof. Dr. Naeem-ur-Rehman 2 , Dr. Amjad Amin 3 ABSTRACT This paper studies the impact of changes in climate in different climatic regions of Khyber Pakhtunkhwa on the productivity of food crops. We find that a degree increase in mean temperature reduces crop yield by approximately 2000 tons. Moreover, we find that climate change has a moderate negative impact on productivity in the Central region and positive impact in the northern part. This study can be used as a standard to envisage its findings to the similar climate zones in Pakistan. Key words: Climate Change, Kharif Crop, Rabi Crop, Temperature, Rainfall. INTRODUCTION Climate change arises due to emissions of greenhouse gases from fuel combustion, deforestation, urbanization and industrialization, resulting variations in solar energy, temperature and precipitation (Upreti, 1998). It is a real threat to life which largely affects water resources, agriculture, coastal regions, freshwater habitats, vegetation, forests, snow cover, and geological processes such as melting, land sliding, desertification and floods all of which have long-term effects on food security and human health (Malla, 2008). ____________________________________________________________________________ 1.
