传统的粮食安全方法是有问题的，因为它们强调粮食生产，而相应地忽视了大量的粮食损失和浪费。我们提供了一个全面的审查有关中国的粮食损失和浪费的现有信息。结果显示，中国整个供应链中谷物的食物损失率（FLR）为19.0% +/- 5.8%，其中消费者群体的食物浪费比例最大，为7.3% +/-4.8%。2010年，中国与粮食损失和浪费有关的总水足迹（WF）估计为1350 +/-600亿m（3），相当于加拿大的WF。这种损失还意味着2，600万+/-1，100万公顷的土地被白白使用，相当于墨西哥的可耕地总面积。从农民到消费者的供应链行为者之间迫切需要就降低粮食高损失率和浪费率的战略进行对话，从而更有价值地利用稀缺的自然资源。
Conventional approaches to food security are questionable due to their emphasis on food production and corresponding neglect of the huge amount of food losses and waste. We provide a comprehensive review on available information concerning China's food losses and waste. The results show that the food loss rate (FLR) of grains in the entire supply chain is 19.0% +/- 5.8% in China, with the consumer segment having the single largest portion of food waste of 7.3% +/- 4.8%. The total water footprint (WF) related to food losses and waste in China in 2010 was estimated to be 135 +/- 60 billion m(3), equivalent to the WF of Canada. Such losses also imply that 26 +/- 11 million hectares of land were used in vain, equivalent to the total arable land of Mexico. There is an urgent need for dialogue between actors in the supply chain, from farmer to the consumer, on strategies to reduce the high rates of food losses and waste and thereby make a more worthwhile use of scarce natural resources.
