ABSTRACT

Food production as global public goods depends upon many factors. This poses a risk to food safety as well as food prices. One of the most prominent factors that affects food production is climate change, which is mainly caused by carbon emissions. The knowledge of the impact of climate change on food production is important in terms of food policies and awareness regarding the issue. The purpose of this study was to empirically investigate the way in which climate change impacts edible food production in 12 selected countries as they had the highest carbon emissions during the 1995–2014 period. Unlike previous studies in the literature, we employ a food production index as an indicator of food production that does not include products such as coffee and tea, which are not nutritious. Further, we investigate the effects of climate change both statically and dynamically. We also do not focus on any specific country or food, as done by many studies in the literature. The results revealed that climate change adversely affects food production, with the production of edible food decreasing with the increase of climate change/carbon emissions.

摘要

作为全球公共产品的粮食生产取决于许多因素。这对食品安全和食品价格构成风险。影响粮食生产的最突出因素之一是气候变化，主要由碳排放引起。了解气候变化对粮食生产的影响对于粮食政策和对该问题的认识非常重要。本研究的目的是实证调查气候变化对 12 个选定国家的可食用食品生产的影响方式，因为这些国家在 1995-2014 年期间碳排放量最高。与以往文献中的研究不同，我们采用食品生产指数作为食品生产指标，其中不包括咖啡和茶等没有营养的产品。更多，我们从静态和动态两方面研究气候变化的影响。我们也不像文献中的许多研究那样关注任何特定的国家或食物。结果表明，气候变化对粮食生产产生不利影响，随着气候变化/碳排放量的增加，可食用粮食的产量下降。
