Pathways for Cleaner, Greener, Healthier Cities: What Is the Role of Urban Agriculture in the Circular Economy of Two Nordic Cities?

As major hubs for energy and resource consumption and carbon emissions, cities are at the forefront of the discussion on the impacts of megatrends, such as demographic changes, technological advancements, and the shift toward climate neutrality. Despite growing literature suggesting pathways for cities to cope with these challenges, the intersection between circular economy and urban agriculture for sustainable urban development has been little explored, especially concerning practical applications. To bridge this gap, this study aimed to explore the role of urban agriculture in promoting the circularity of resources at the city level. Aarhus, in Denmark, and Ås, in Norway, provide the empirical context for this discussion that uncovers the barriers that impact the successful implementation of C-E practices in the context of UA and delves into how these obstacles challenge cities in transitioning to circular and sustainable food production models. Using a case study approach and qualitative data sources, the findings suggest that while urban agriculture demonstrates potential in reducing resource consumption, it requires further evidence-based research and clear monitoring tools to assess its environmental impact and economic viability. Obstacles to urban agriculture implementation include regulatory challenges, social acceptance of waste, high investment costs, and limited recognition of its indirect impacts. Concerning recommendations, local governance and public policies were found to play a central role in fostering circular urban agriculture by promoting collaboration, fostering innovation, developing regulatory frameworks, and showcasing successful examples.
