Decoupling the climatic and carbon dioxide emission influence to maize crop production in Pakistan

Global warming influencing the agricultural production in several ways due to rainfall, temperature and carbon dioxide emission. The objective of this study is to investigate the climatic and carbon dioxide emission influence to maize crop production in Pakistan for the period of 1988-2017. We used an ARDL approach and Granger causality test to check the dynamic linkage between carbon dioxide emission, maize crop production, area under maize crop, water availability, rainfall and temperature with the evidence of long-run and short-run. Analysis results revealed that maize crop production has positive coefficient that demonstrate the long-term association with carbon dioxide emission with p value 0.0395. Similarly, results also showed a long-run association among water availability, rainfall and temperature with carbon dioxide emission with having positive coefficient and p values 0.0000, 0.0014 and 0.0001. Unfortunately, the coefficient of area under maize crop showed a negative linkage with carbon dioxide emission. Possible conservative policies are needed from the Pakistani government to reduce carbon dioxide emission in order to enhance the agricultural production as well as to boost the economic growth.
