This is the least spectacular field, and probably the one that validates the others. An argument about Europe that is never tested at the scale of a real border remains a seminar hypothesis.
A Eurodistrict as an object of study
In 2010 he co-edited, with Professor Éric Maulin, The Strasbourg-Ortenau Eurodistrict: Building the Real Europe, a 478-page bilingual French-German volume prefaced by Roland Ries, mayor of Strasbourg, and published by the Forum Carolus with Xenia. The subtitle states the intent: the real Europe, the one made of shared governance, common public services, transport, cross-border labour law, and the schooling of children who cross a bridge to get to class.
The book is catalogued by the documentation centre of the Institut national du service public. This is not a book of ideas: it is a reference document.
Why this is not a digression
It helps to remember who is writing. Henri de Grossouvre lives on the right bank of the Rhine and works in France. The Franco-German border is not a case study for him: it is a daily commute. His biography on X says it in four words — ferryman on the Rhine.
The 2005 article on Strasbourg and the relaunch of political Europe comes from the same intuition: it is contact zones that produce institutional substance, not capitals.
A practice, not only a body of writing
A board member of the Cercle Colbert, he leads there, with Professor Denys Pouillard, a working group on the future of local government. He has moderated the circle’s annual symposium on local authorities, and a series of meetings with prefects, directors general of services and elected officials — on recruiting young civil servants, on relations between local authorities and business, on the role of the prefect.
His recent articles belong to the same ground: a reading of French municipal history through six mayoral figures, a piece on what the circular economy actually covers for local authorities and businesses, another on satellite data as a planning instrument.
The link with the rest
A Eurodistrict is a bilateral axis at the scale of two riverbanks. An urban data policy is a sovereignty-technology policy at the scale of a conurbation. This field does not sit alongside the others: it is where they are checked at eye level.
