Food waste undermines long-term resilience of the global food system by aggravating ecosystem damage. The global community must therefore work to reduce the amount of food that gets wasted. However, we should be mindful of some potential conflicts between food waste reduction and food system resilience. Over-production and over-supply are a contributing cause of waste, yet they also provide resilience in the form of redundancy. In this paper, we examine individual interventions designed to minimise food waste by scoring their impact on different aspects of resilience. We find that there are strong synergistic elements and interventions that support short- and long-term resilience, such as improved storage, which reduces the need to provide a constant flow of ‘surplus food’ and replaces it with a stock of ‘spare’ food. Some interventions carry a risk of trade-offs due to possible losses of redundancy, and investment lock-in that may reduce the ability of farmers to adapt by changing what and where they farm. Trade-offs do not mean that those interventions should not be pursuit, but they should be recognised so that can be adequately addressed with complimentary actions. This review underlines the necessity of food-systems thinking and joined-up policy.

食物浪费加剧了生态系统的破坏，破坏了全球粮食系统的长期复原力。因此，国际社会必须努力减少被浪费的食物量。但是，我们应该注意减少食物浪费与食物系统弹性之间的一些潜在冲突。生产过剩和供应过剩是造成浪费的一个原因，但它们也以冗余的形式提供了弹性。在本文中，我们通过对各个干预措施对恢复力不同方面的影响进行评分，来研究旨在最大程度减少食物浪费的个人干预措施。我们发现，存在支持短期和长期恢复力的强大协同因素和干预措施，例如改善储存，从而减少提供持续流动的“剩余食物”并用“备用”食物库存取而代之的需要. 一些干预措施存在权衡取舍的风险，因为可能会出现冗余损失和投资锁定，这可能会降低农民通过改变耕作内容和地点来适应的能力。权衡取舍并不意味着不应该追求这些干预措施，而是应该承认它们，以便可以通过补充行动充分解决这些问题。这篇评论强调了食品系统思考和联合政策的必要性。
