This thesis inquires into the implementation of cross-border spatial planning strategies. Based on the study of cases such as Attert (Belgium), Backerich (Luxembourg), Montmédy (France), and Gaume (Belgium), as well as of the Vosges du Nord/Pfälzerwald Transboundary Biosphere Reserve, the author develops a typology of the different phases of the construction of a cross-border territory project.
