    Question E: Re-optimizing the food system
    Recent events have shown us that our global food system is unstable even in generally well-served parts of the world. Part of the reason for these instabilities is our current global system of large-scale countries and international food producers and distributors. This food system allows for relatively cheap and efficient production and distribution of food, thus indicating that the current model prioritizes
    efficiency and profitability. Despite the high efficiency of the system, the United Nations estimates that 821 million people worldwide suffer from hunger[1] even if there is enough food to feed everyone in the world. [2] Food insecure people, people who cannot get enough affordable and nutritious food, live on every continent, every country, and every community. Moreover, even in rich countries, food shortage areas will appear, where there is not enough food and nutrition. In addition, the current food system leaves a huge environmental footprint, accounting for "29% of greenhouse gas emissions, up to 80% of biodiversity loss, 80% of deforestation, and 70% of freshwater use."[3] As our global population continues to increase, and we have experienced decades of environmental abuse, the ability to produce more food while maintaining or even improving our environmental health has never been more important. Therefore, a comprehensive review of our current food system seems to be a reasonable and necessary effort. The International Portfolio Management (ICM) Committee challenges your team to reimagine and re-prioritize our food system
    by developing a model. Although the ICM committee will let your team decide which aspects of these systems are worthy of being the focus of your modeling activities, you should provide a sufficiently robust food system model that can be based on different levels of efficiency, profitability, sustainability and / Or fair adjustment to optimize. Whether your focus is global or local, food systems are complex. Some issues you should consider include but are not limited to:

  • What happens if a food system is optimized to achieve fairness and sustainability? How is this system different from the current system? How long will it take for such a system to be implemented?

  • What are the benefits and costs of changing the priority of the food system? When will they happen? How are these benefits and costs different between developed and developing countries?

  • Once you have developed your food system model, apply your model to at least one developed country and one developing country to support your findings.

  • Discuss the scalability (for larger or smaller food systems) and adaptability (for other regions) of the model. Interdisciplinary and diverse groups from the fields of environmental science, nutrition policy and science, government and mathematics, the ICM Committee looks forward to you The final report. Your PDF solution does not exceed 25 pages and should include:

  • One page summary table.

  • table of Contents.

  • Your solution.

  • List of references.
    Note: The new ICM competition in 2021 now has a 25-page limit. All aspects of your submission are calculated on the 25-page limit: summary table, table of contents, main body of the solution, images and tables, reference list and any appendices.
    Vocabulary
    Food is not safe: The inability to reliably obtain enough affordable and nutritious food. This may be the result of food shortages.
    Food scarcity: When there is not enough food and nutrients to sustain the local population. Scarcity may be caused by insufficient food produced or uneven distribution of resources.

    Thinking analysis

Problem center: re-optimizing the food system.
Subject requirements:
(1) First, we must understand the classification and distribution of food, the current operation mode of the food system (import and export, the consumption capacity of national or provincial units), and optimize or rebuild the food system to ensure fairness , Sustainability; Analyze and compare the difference with the existing food operation mode; visualize the process of reconstruction of the ideal food model.
(2) Determine the important independent variables of the cost and benefit of the food system, such as major food countries and provinces, and analyze the difference between the influence of these factors on the system in developed and developing countries.
(3) Model solving. Based on the food system established in the previous two questions, the changes in food transactions (import and export, digestion, etc.) in several countries are solved separately.
(4) Applicability and scalability of the analysis model in different types of countries? Give the model optimization plan.

Note: Interested students first arrange for individuals to collect data in statistical yearbooks or related foreign websites to understand the operating mode of the existing video system.
