Climate change impact on food security in Pakistan
Main Article Content
Abstract
The climate change has valuable and measurable effects in Pakistan. The basic purpose of this research was to known climate change impact on food security variable particularly wheat yield in the province of Punjab. Time series data used for estimation from 1990 to 2022 to gain the desired results or objective with sample size 32. Yield is dependent variable while the mean minimum temperature for sowing phase, mean minimum temperature for vegetation stage, mean maximum temperature for maturity stage and rainfall are used as independent variable. ARDL Bound test is used to check co integration among the variables. The results have indicates that if one Centigrade mean minimum temperature for sowing phase will increased the wheat yield decreased by 8.879016 kg and shows significant relation among the variables. At the Vegetation phase if mean maximum temperature increased by one Centigrade the yield of wheat decreased by 13.705017kg shows significant relation. At the maturity phase wheat productivity increased by 1.073163 kg due the result of increase one degree centigrade of mean maximum temperature. If sufficient amount of rain which increased the wheat yield by 70.921702 kg. It concludes that climate change is big tool of wheat yield at all period of wheat development.
