课程名称：全球食品系统的转型 概述：联合国预测，到2050年，全球人口将达到90亿到100亿。提供营养充足的食品是一个巨大的挑战，单靠扩大现有的食品生产和消费方式无法解决这一问题。确保人类获得营养食品是可持续发展相关决策的核心。农业是全球森林砍伐的主要因素，负责80%的森林砍伐，食品系统释放出29%的全球温室气体，生产肉类需要相当于北美和南美的土地，用水方面，农业占用70%的淡水资源。这些令人震惊的数字表明，我们需要重新思考并转型全球的食品生产、分配和消费方式。 本课程聚焦于如何使食品系统更加可持续，包含四个模块，每个模块关注食品系统可持续发展的一个关键要素：(1) 提升小农户的能力，(2) 转变大规模生产，(3) 减少损失，(4) 智能饮食。在这些关键领域中，我们将遇到来自全球各地的人们，他们每天努力寻找和传播有效的解决方案。 本课程将全球食品系统转型所面临的挑战与在课程中遇到的优秀人士所开发的解决方案相结合，给我带来了巨大的启发。我坚信全球食品系统能够转型，以可持续的方式满足90亿到100亿人的需求，我邀请您加入我，共同参与这个转型之旅！ 课程大纲： 1. 全球食品系统简介 - 本模块介绍了全球食品系统面临的挑战，介绍了甜甜圈经济学和地球边界框架，并阐述了全球食品系统的关键角色。 2. 提升小农户的能力 - 重点关注改善小规模农户的条件，尤其是在全球南方，以面对信息、资金和化肥等问题。 3. 转变大规模生产 - 关注工业化大规模农业生产的变革，识别实现可持续食品系统所需的变革类型及相关案例。 4. 减少损失 - 关注减少食品浪费与损失，指出约三分之一生产的食品未被消费，并探讨应对气候变化的减损与废物策略。 5. 智能饮食 - 关注饮食习惯的改变，强调全球北方需通过更智能的饮食方式腾出空间来满足全球南方的营养需求。 6. 结论：转型究竟意味着什么？ - 探讨如何将提升小农户、转变大规模生产、减少损失和智能饮食结合，形成一个可持续的全球食品系统，满足未来人口的营养需求，同时保护环境与控制全球变暖。
Name:Introduction to the Global Food System
Description:This first module is an introduction to the challenges facing society when we talk about the global food system. The Doughnut Economics and Planetary Boundaries frameworks are presented and the crucial role of the global food system described. Four areas of intervention in terms of transforming the global food system are identified. In addition, the four “levers” or “tools” identified in the UN 2019 Global Sustainable Development Report that society has at its disposal to transform the global food system are presented: Technology, Governance, Finance and Behavioral Change. These levers are all further developed in the following modules.
Name:Boosting the Small
Description:One of the essential elements for bringing the global food system onto a sustainable trajectory, is boosting, i.e., improving conditions for small-scale farmers, especially in the Global South. In this module, we look at the major challenges confronting small-scale farmers when it comes to access to information, finance, fertilizers, etc. These challenges can be met through the use of existing technologies, government intervention, and consumer awareness.
Name:Transforming the big
Description:The second essential element in a sustainable transformation of the global food system takes focuses on changes in industrialized, large-scale agricultural production. These practices must be changed in order to have a sustainable food system. This module identifies some of the kinds of changes needed and presents case studies showing how some actors are beginning the transformation process.
Name:Losing less
Description:The third essential element for transforming the global food system is reducing food loss and waste. Today, about a third of all of the food produced is never consumed. Thus, no nutritional value was created for the environmental degradation associated with the production of a large percentage of the food produced. If we can limit food loss and waste, it will be possible to stay within our planetary boundaries while feeding the increasing world population. A challenge in reducing this loss and waste is actually climate change. This module examines strategies for reducing food loss and waste.
Name:Eating Smarter
Description:The fourth and final essential element for achieving a sustainable food system is changing our diets. While an increasing population in the Global South will need access to nutrient-rich foods, the Global North will have to make room for this development by eating smarter. Meat production is especially damaging to the climate and environment. Many people’s health would benefit by eating less meat and it is possible to easily replace meat with alternative sources of protein. This module focuses on when and how it is easiest to change eating habits and what we need to change them to!
Name:Conclusion: What does transformation really mean?
Description:The Finale. In this module, we examine what it would mean for the global food system if the potentials identified through Boosting the Small, Transforming the Big, Losing Less, and Eating Smarter were to be combined. The module argues that it is possible to develop a global food system that can meet the nutritional needs of 9-10 billion people without destroying the environment and while keeping global warming within the 1.5 - 2 degrees Celcius guardrail identified in the Paris Agreement. Doing so will, however, require a strong focus on transforming the global food system.
The UN predicts we will be 9-10 billion people on Earth in 2050. Providing so many people with nutritious foods is a massive challenge and one that cannot be met by simply upscaling current practices regarding food production and consumption. Providing humanity with nutritional food is at the center of all decisions related to sustainable development. Agriculture is responsible for 80% of global deforestation. The food systems release 29% of global greenhouse gasses. We use an area equivalent to North and South America combined for the production of meat for consumption or to produce the food necessary to feed the animals we eat. 70% of fresh water use is related to agriculture. These figures are staggering, and they show us, that we need to rethink and transform the way we produce, distribute and consume food worldwide. This course focuses on how food systems can become more sustainable. It consists of four modules where each focuses on an essential ingredient towards developing more sustainable food systems: (1) Boosting the small, (2) Transforming the big, (3) Losing less and (4) Eating smarter. In each of these key areas, we will meet people from different countries around the world, who labor every day to find and spread solutions that work. Connecting the challenges that must be overcome to develop a sustainable global food system with the solutions being developed by the amazing group of people you meet in this course has been a huge source of inspiration for me. I truly believe that the global food system can be transformed to sustainably meet the needs of 9-10 billion people and, with this course, I dare you to join me!
