In the autumn of 2015, a module entitled «Landscape Issues» (in French, Enjeux paysagers) was introduced in the first semester of the University Master of Environmental Sciences (in French, Master Universitaire en Sciences de l'Environnement, MUSE), an interdisciplinary and interfaculty training course at Geneva University (Switzerland). This new module is part of a first stage in the initiation to the interdisciplinary study of environmental themes. The article describes this teaching experiment in a reflective mode shared by the authors, all of whom are teachers of different disciplines and work in the MUSE programme. The landscape is positioned here as a «laboratory-concept» for fostering links between the disciplines taught and promoting interdisciplinarity, or transdisciplinarity, between social, natural and exact sciences.
