ABSTRACT

As an important part of natural resource, food plays an important role in people's lives. Based on the perspective of fairness, this article assesses the state of global food development. We conduct researchs on food equity in-depth and analyse influencing factors of the regional differentiation of equity levels, thus making targeted policy recommendations. We study the overall fairness of the global food system by solving the weighted coefficient of variation and the Gini coefficient. Through the Theil Index, we decompose the overall difference into differences between the six continents and differences within the six continents. This article creatively defines the economy-food matching index and energy-food production matching index. We focus on analysing and evaluating the fairness of water utilization in all continents based on economic and ecological dimensions. The conclusion shows that the overall fairness of the food system is poor. The value of the Gini coefficient has been declining year by year. However, it kept the level above 0.4, indicating that food equity has gradually improved. From the data analysis results of the Theil index, we can find that Europe, North America and Oceania are economically fair. In particular, Europe has the highest MIe index and the highest degree of fairness. Asia, Africa and South America are in a state of economic inequality. In particular, Africa has the lowest index, which shows that it is in a more serious state of unfairness.
