CBEN monthly calls had Sharon Mireri, a postdoctoral scientist involved in the RUNRES Project, offer an enlightening overview of the project’s progress and its innovative contributions to the circular economy. The RUNRES Project, which stands for Rural-Urban Nexus: Establishing a Nutrient Loop to Improve City Region Food System Resilience, is a groundbreaking initiative implemented in four countries—Ethiopia, the Democratic Republic of Congo (DRC), Rwanda, and South Africa. Coordinated by ETH Zurich and funded by the Swiss Agency for Development Cooperation (SDC), the project is driven by a central mission: to close the nutrient loop and improve the resilience of food systems across city-regions.
