ABSTRACT

In this paper, an FSI model has been proposed, which uses the multi-index comprehensive evaluation method to evaluate the food security level of 172 countries from 2000 to 2014 based on the establishment of the data set of food security evaluation factors and influencing factors. The FSI model takes FAOSTAT as the data source of food security evaluation factors, further refines and improves the food security framework according to the available data, and forms a perfect food security evaluation index system. By interfering with the indicators in the FSI model, we propose that the global food system can achieve the minimum goal of fair distribution and sustainable food development by 2030. Specifically, we use the grey Verhulst model to predict and compare the FSI curve with the perturbed FSI curve to evaluate the effectiveness of perturbed FSI. Finally, the improved food system is applied to Japan and China. According to the result analysis, the model proposed in this paper can evaluate the actual situation scientifically and reasonably, and the model is relatively stable and scalable.
