加强粮食系统的环境可持续性需要了解生产和消费的影响。随着食品供应链变得越来越复杂和相互关联，它们也为理解消费对环境的影响提供了独特的背景。这对于理解粮食系统的生产和消费影响之间的脱节，以及最终设计、评估和实施干预措施以提高粮食系统的安全性、复原力和可持续性至关重要。使用公开的数据集和基于优化的框架，我们提出了一个县到县的牛肉供应链在美国的网络模型。该模型用于将牛肉消费的消费影响与遥远地区的生产联系起来，并将其归因于这些影响，特别是基于水的影响。我们特别关注牛肉系统，因为它在美国消费者的饮食和环境可持续性讨论中的重要性。这项工作的结果显示了消费和生产县之间的空间脱节，2017年约有220亿立方米的蓝色虚拟水被转移，主要是从北方和南部平原向沿海地区转移。这些结果突出了从生产和消费两个角度理解环境影响的重要性。
Enhancing the environmental sustainability of food systems requires an understanding of both production- and consumption-based impacts. As food supply chains become increasingly complex and connected, they also present a unique context in which to understand the environmental impacts of consumption. This is critical for understanding the disconnect between production- and consumption-based impacts of food systems and ultimately designing, evaluating, and implementing interventions for improving security, resilience, and sustainability of food systems. Using publicly available datasets and an optimization-based framework, we present a county-to-county level network model of beef supply chains in the United States. The model is used to connect and attribute the consumption-based impacts of beef consumption to production in distant locations, specifically focusing on water-based impacts. We specifically focus on the beef system because of its importance in the diet of U.S. consumers and in environmental sustainability discourse. The findings from this work show the spatial disconnect between the consumption and production counties with approximately 22 billion m3 of blue virtual water being transferred for the year 2017, mainly from the northern and southern plains toward the coasts. These results highlight the importance of understanding environmental impacts from both production and consumption perspectives.
