    Conceptualising ‘Cultural Landscape Commons’: Retracing Ecological Thinking from the Swiss Alpine Landscape to Social-Ecological Systems by Nicole de Lalouvière

    Published 2021-05-01
    “…This paper retraces the fundaments of the ‘nature-culture’ divide within the study of Swiss alpine ‘cultural landscape commons’, showing how this notion was shaped by early ecological thinking expressed through environmental determinism, dynamic systems, and cultural ecology. These fields of research are seen as precursors to some of the currently dominant concerns within commons scholarship more broadly: defining system boundaries, distinguishing endogenous from exogenous forces, and identifying change patterns over extended spatiotemporal scales. …”
