Leveraging circular nutrients to improve the sustainability of peri-urban agriculture

Urban Farm DB summary

This study investigates the spatial and temporal effects of nutrient circularity strategies in peri-urban agriculture (peri-UA) using a regionalized life cycle assessment tool, focusing on the Metropolitan Area of Barcelona. It examines how nutrient recovery from municipal waste impacts climate change, eutrophication, resource depletion, and water consumption. The research finds that applying compost with current waste management infrastructure can reduce the carbon footprint of peri-UA areas by up to 85%.
