In this class, we will explore China's experience in post-harvest food loss reduction, which has been crucial in ensuring food security and reducing food waste. We will cover various topics, including China's achievements in food saving and loss reduction, policies and regulations, technology and application equipment, cultural atmosphere, and food security during the COVID-19 pandemic. We will start by discussing the world food situation and security risk, which will provide a context for understanding the importance of food loss reduction. Next, we will examine China's remarkable achievements in food saving and loss reduction, which have contributed significantly to ensuring food security for its large population.

Moreover, we will explore the role of farmers in reducing food loss and waste and the various measures taken to ensure their food security. Finally, we will discuss how China has ensured a guaranteed food supply during the COVID-19 pandemic by implementing various measures, including food assistance programs and the use of e-commerce platforms for food delivery. Overall, this class will provide students with valuable insights into China's experience in post-harvest food loss reduction and its implications for global food security and sustainability.
