This study maps the U.S. agri-food distribution onto real-world highways, railways and waterways to quantify the trade-offs between cost, carbon emissions, and path redundancy across different transport modes. It finds that highways cost three times as much, produce 60 times more carbon and have the highest path redundancy relative to waterways. 

This article collection details several case studies related to assessing the barriers and opportunities for a sustainable food system transformation. This, for the authors, means an increased consumption of plant-based foods and lower levels of meat and dairy consumption, especially in the global North. The collection seeks to challenge incumbent actors and structures which the authors claim resist the critical transformative changes required whilst fostering new values, norms, and paradigms that could contribute to the societal change necessary for food system transformation. The case studies cover topics such as the polarisation of the animal-free and animal-centric food system narratives, new and alternative protein industries, different socioeconomic systems of agriculture and unique perspectives on human-animal relationships.
