The Trinational Eurodistrict Basel

Read the PDF edition (2 pages)

The local authorities of the agglomeration first organised their cooperation in 1995 under the name Trinationale Agglomeration Basel (TAB), a project body that prepared studies on transport, urban development and the landscape along the Rhine. In 2007 the participants transformed the structure into an association under French law, the Trinationaler Eurodistrict Basel (TEB), with its seat in Village-Neuf.1 Its members are the cantons of Basel-Stadt and Basel-Landschaft, communes and associations of communes from Aargau and Solothurn, the district of Lörrach and the German towns of the area, together with the French communauté d'agglomération Saint-Louis Agglomération. A council with representatives from the three countries steers the association, while a small secretariat coordinates projects.

The TEB has no legislative power. It works through planning, the coordination of projects and the management of European funds, especially from the Interreg programme of the European Union, in which Switzerland participates under its New Regional Policy.2 Its significance lies in the habits of cooperation it has created. Planners in Basel, Lörrach and Saint-Louis now meet regularly, exchange data and prepare joint concepts for development areas near the borders, such as the Rhine banks at the point where the three countries meet. When a new tram line crosses the border, years of preparatory work in such bodies usually precede the formal treaty or agreement that makes it possible.
