ABSTRACT

Current food system prioritizes efficiency and profitability. Despite the efficiency of the system, food insecure and scarcity still occur. In addition, the current food system has left a huge environmental impact. Therefore, a comprehensive assessment of our current food system seems reasonable and urgent. Hence, the re-optimizing food systems have received our attention.we modify the initial model by taking Food Savings (FS) and Environmental Improvement (EI) into account. Then we get MPFE model, which satisfy fairness and sustainability. Through utilizing data in China, we get the total score and scores for four aspects in China during the ten-year-period, so that we put forward suggestions for improvement: Increase investment in environmental improvement under the condition of ensuring food production and transportation and steady increase in market profits through publicity and education to enhance consumers' habits and concepts to reduce food waste.
