In 2015, the United Nations and the G20 put food loss and food waste on the global agenda. While progress has been made since then, the scale of the problem persists because food loss and food waste are measured together, not separately. The paucity of data also poses a challenge. This article reviews the measurements, causes, and determinants of food loss as well as the interventions to reduce it. The review finds that food loss is considered in isolation, even though it is one of the causes and results of how agrifood systems function. The review calls for improved microdata collection and standardized measurements to separate food loss from food waste. Such efforts would help integrate feedback loops and cascading effects across the value chain with agrifood systems to identify intervention hot spots, trade-offs, and synergies of interventions as well as the effects of food loss reduction on socioeconomic, environmental, and food security goals.

农业粮食体系的粮食损失：我们所知道的


2015 年，联合国和 G20 将粮食损失和粮食浪费列入全球议程。虽然自那时以来取得了进展，但问题的规模仍然存在，因为食物损失和食物浪费是一起衡量的，而不是分开衡量的。数据的缺乏也带来了挑战。本文回顾了食物损失的测量、原因和决定因素，以及减少食物损失的干预措施。审查发现，尽管粮食损失是农业粮食体系运作的原因和结果之一，但人们将其孤立地考虑在内。该审查呼吁改进微观数据收集和标准化测量，以区分食物损失和食物浪费。这些工作将有助于将整个价值链的反馈循环和级联效应与农业粮食体系相结合，以确定干预措施的干预热点、权衡取舍和协同作用，以及减少粮食损失对社会经济、环境和粮食安全目标的影响。
