Quantifying food loss along the animal products supply chain in China with large-scale field-survey based primary data

摘要: Addressing food loss along the supply chain in developing countries is often hindered by low quantity and quality of food loss data. This is particularly important for the animal products supply chain of China, the world's most populous country that is experiencing dietary structure change towards more animal-based food.
