This systematic review examines the intersection of systems thinking and learning theory in addressing rural–urban challenges in light of increasing global urbanization. We explore how different dimensions of systems thinking—ontological (how we understand systems) and epistemological (how we think about systems)—align with single-, double-, and triple-loop learning in rural–urban research from 2014 to 2024. Through a rigorous screening process of the peer-reviewed literature, we analyze how theoretical frameworks manifest in research approaches, methodological choices, and learning outcomes. Our findings reveal promising developments and persistent gaps in current approaches, and suggest pathways for more integrated theoretical and methodological frameworks. We also highlight the need for studies that develop knowledge and practices that support collective learning and joint trajectories towards sustainability from a cross-sectorial perspective in rural–urban geographies. This synthesis contributes to discussions on how to effectively address complex challenges at the rural–urban interface while advancing both theoretical understanding and practical application.

Urban freight transport generates significant negative externalities in the form of noise, congestion, and environmental impacts. Freight consolidation centres could be seen as a potential solution, offering benefits such as shorter delivery distances and fewer delivery routes. However, implementation of freight consolidation centers requires collaboration between actors with conflicting interests and goals. This study proposes a collaborative business model framework for freight consolidation centres. The novelty of the study lies in conceptualising collaboration as an outcome-based partnership and extending the Business Model Canvas with collaboration-specific components. This framework was empirically tested and refined through a pilot project in Gothenburg, applying the principles of engaged scholarship. The results indicate that last-mile consolidation can significantly improve operational efficiency and enable sustainability gains. At the same time, structural, economic, and organisational barriers need to be addressed to realise all benefits of the collaborative business model. The findings particularly highlight the need for deeper institutionalisation of collaborative practices, including the integration of new norms, procedures, and policies into the business models of the individual actors involved.
