- W3205240460 abstract "Food security refers to the state where everyone can stably get enough food. If the food system can meet our nutritional needs at different stages of life in an economical, easy and sustainable way, it can be defined that the food system is safe. People make plans to determine the long-term capabilities and direction of the food system. The 2020 COVID-19 pandemic and the outbreak of the locust plague in eastern Africa have dimmed the economic outlook. Therefore, the Ω model is established which uses the entropy method to quantify the survival or decline of a food system with biodiversity, self-sufficiency, and average dietary energy supply. It is well known that the current state of the food system pays more attention to efficiency and profit. The Ω model adds the influence of environment, diet, gender differences, wealth gap, and political factors on the sustainability and fairness of the food system to the existing food system. The comprehensive evaluation of these four aspects of the food system greatly optimizes the reliability and applicability of the model, and helps decision-makers accurately formulate relevant policies. At the same time, the Ω model evaluates the food systems of developed and developing countries. It selected an important indicator from the three aspects of environment, equity and eating habits for the autoregressive integrated moving average model time series analysis, and set a threshold for the establishment of a fairer and sustainable food system." @default.
