Comparing the carbon footprints of urban and conventional agriculture

January 22, 2024 | Nature Cities |

Introduction: Urban agriculture (UA) is seen as a key solution for creating sustainable urban food systems. In collaboration with European researchers, a US research team based in University of Michigan compared the environmental impact of UA to conventional agriculture across 73 sites in Europe and the United States. 

Key findings: Results showed that UA produces six times more carbon emissions per serving compared to conventional farming. However, some UA crops and sites outperform conventional agriculture, suggesting ways to reduce climate impact. Recommendations include cultivating crops typically grown in greenhouses or air-freighted, prolonging UA infrastructure lifespan, and utilizing urban waste for inputs. Despite UA's higher carbon intensity, it offers social benefits like improved mental health and community building. Future research should explore strategies to mitigate UA's environmental impact while maximizing its social and nutritional benefits.
