Circular economy (CE) is concept that has recently emerged, especially relevant in cities, and that contrasts the linear economic system. Research gaps in the analysis and implementation of circular economy in cities are a significant barrier to its implementation. This paper presents a multi-sectorial and macro-meso level framework to monitor (and set goals for) circular economy implementation in cities based on Porto, Portugal as a case study.
Transition pathways are compared to the land use domain of the Netherlands and Portugal. The land use domain analyses land systems and the changes within them and typically involves the analysis of land cover and land use. 4 main regimes were identified, three of which are common to both: agriculture, nature, and urban, and one which is different for each. The Dutch and Portuguese niches under study are all examples of regime transformation niches.
