Town-mountain cooperation: what a study visit in the Chartreuse teaches us
On 27 January 2026, ADRETS organised a study visit in Saint-Pierre-de-Chartreuse on cooperation between towns and mountain territories. BMAX handled the photo and video coverage of the day, working alongside Charlie Divry (1 Pact 2 Côté). A preserved massif surrounded by more than 800,000 residents of the Grenoble plain, according to one speaker present that day: here is what the day reveals about how a mountain territory builds balanced ties with the metropolitan areas around it.

Why a mountain massif cannot live in isolation
The Chartreuse is a preserved territory, yet it is surrounded by more than 800,000 residents of the Grenoble plain. A local elected official put it plainly during the day: mountain residents work down in the plain, get medical care down there, and study down there, while the metropolitan area in turn benefits from the mountain territory around it. The exchange between town and mountain is not optional, it is an existing reality that needs organising rather than enduring.
The concrete tools of town-mountain cooperation
On the ground, this cooperation takes a precise institutional shape. The Chartreuse has set up joint governance with the Cœur de Chartreuse local authority group and Grenoble-Alpes Métropole, then signed a reciprocity agreement in 2023 (a national scheme created in 2015) with the metropolitan area and the department. This agreement centres on a site committee set up at Col de Porte, bringing together elected officials, private businesses established in the territory, and associations. A citizens’ convention, with residents chosen by lot, complements this setup to surface questions and perspectives that public meetings alone don’t always bring forward.
The role of transdisciplinary research in territorial decisions
One of the day’s most concrete contributions came from research. Transdisciplinary projects, bringing together academic researchers and non-academic stakeholders (elected officials, businesses, citizens), help make sensitive situations more objective, such as that of the Saint-Pierre-de-Chartreuse ski resort, structurally in deficit and undergoing major reconfiguration. By combining quantitative data, field interviews and analysis of public policy documents, research gives all stakeholders a shared view of the situation, a necessary condition for shifting entrenched positions.
Frequently asked questions about town-mountain cooperation
What is a reciprocity agreement between local authorities?
It is a French national scheme created in 2015 that formalises reciprocal commitments between an urban territory (a metropolitan area) and a neighbouring rural or mountain territory, on subjects such as food, tourism or planning.
Why involve a citizens’ convention in these decisions?
Residents chosen by lot bring an informed but non-institutional perspective, surfacing questions and priorities that standard public meetings often leave aside.
How does research concretely help a mountain local authority?
By documenting, with quantitative and qualitative data, what is actually happening in the territory, transdisciplinary research gives elected officials an objective basis for deciding on sensitive issues, such as the future of a loss-making ski resort.
A cooperation that gets built, documented and told
Cooperation between town and mountain isn’t decreed, it gets built agreement by agreement, committee by committee, and it takes time that today’s tendency to retreat into oneself makes all the more valuable. Filming a day like the one ADRETS organised in the Chartreuse helps document this approach and share it with other territories facing the same balancing act, as with ADRETS’ Services and Territories meeting in Veynes on livability.
