Reoptimization of the Food Supply System

The team develops a model to reprogram and prioritize food systems to strike the best balance between equity, ecological conservation and profitability, and provides practical recommendations based on our findings, with a focus on equity and sustainable development. First, we divided all countries and regions in the world into importers (food-deficit countries), exporters (food-rich countries), and food-subsistence countries, analyzed two indicators of per capita food availability and per capita GDP over the past 15 years, and built an agricultural system evaluation model. To ensure the accuracy of the model, our team collected ecological factors recognized by each country for analysis, including land salinization and land degradation. We concluded that the model optimizes both anthropogenic and non-anthropogenic factors for greater stability and resilience to adversity compared to the old model. This is expected to be achieved within five years. We simulated GDP per capita, achieved profitability, and analyzed and compared the economies of different countries. Based on the available data, we obtained the following results: the regions with a clear increasing trend in per capita food availability are mainly located in Northeast China, Southwest China and Eastern Europe.
