全球粮食系统必须成为减缓温室气体(GHG)、优化用水和减少氮污染战略的一部分。来自这些领域研究的见解可以为建立可持续食品系统的政策提供参考，但在建立对可持续努力是否与供应链弹性竞争的理解方面所做的工作有限。这项研究在全球食品系统对温室气体排放、用水和氮污染的贡献的背景下，探索了美国城市的食品供应弹性和环境影响之间的相互作用。利用县级农业数据，我们评估了全美城市食品系统的用水量、温室气体排放量和氮素损失，并将这些与以供应链多样性为代表的食品供应弹性进行了对比。我们的结果强调了供应链的弹性和可持续性可以同时存在，并且不一定相互竞争。我们还发现，在南方城市的环境领域，特别是墨西哥湾沿岸和大平原南部的城市，人均足迹显著。食品供应链韧性得分在0.18至0.69之间，西南和大平原地区得分较低，东北部和中西部地区表现出较高的韧性。我们发现了几个供应链弹性较高、对环境影响中等或较低的城市，以及影响较高和弹性较低的地区。这项研究提供了对在美国创建可持续城市食品系统的潜在权衡和机会的见解，强调了同时考虑弹性和环境影响的战略的必要性。
Global food systems must be a part of strategies for greenhouse gas (GHG) mitigation, optimal water use, and nitrogen pollution reduction. Insights from research in these areas can inform policies to build sustainable food systems yet limited work has been done to build understanding around whether or not sustainability efforts compete with supply chain resilience. This study explores the interplay between food supply resilience and environmental impacts in US cities, within the context of global food systems' contributions to GHG emissions, water use, and nitrogen pollution. Utilizing county-level agricultural data, we assess the water use, GHG emissions, and nitrogen losses of urban food systems across the US, and juxtapose these against food supply resilience, represented by supply chain diversity. Our results highlight that supply chain resilience and sustainability can simultaneously exist and are not necessarily in competition with each other. We also found a significant per capita footprint in the environmental domains across Southern cities, specifically those along the Gulf Coast and southern Great Plains. Food supply chain resilience scores ranged from 0.18 to 0.69, with lower scores in the southwest and Great Plains, while northeastern and Midwestern regions demonstrated higher resilience. We found several cities with high supply chain resilience and moderate or low environmental impacts as well as areas with high impacts and low resilience. This study provides insights into potential trade-offs and opportunities for creating sustainable urban food systems in the US, underscoring the need for strategies that consider both resilience and environmental implications.
