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.

气候和二氧化碳排放对巴基斯坦玉米作物生产的影响脱钩

由于降雨、温度和二氧化碳排放，全球变暖以多种方式影响农业生产。本研究的目的是调查 1988-2017 年气候和二氧化碳排放对巴基斯坦玉米作物生产的影响。我们使用 ARDL 方法和格兰杰因果检验来检查二氧化碳排放、玉米作物产量、玉米作物面积、水资源可用性、降雨量和温度之间的动态联系，并提供长期和短期的证据。分析结果表明，玉米作物产量具有正系数，表明与二氧化碳排放存在长期关联，p 值为 0.0395。同样，结果也显示了可用水量之间的长期关联，具有正系数和 p 值 0.0000、0.0014 和 0.0001 的二氧化碳排放的降雨和温度。不幸的是，玉米作物面积系数与二氧化碳排放量呈负相关。巴基斯坦政府需要采取可能的保守政策来减少二氧化碳排放，以提高农业生产并促进经济增长。
