Matinée de co-construction des 72h de l'écologie 2027 - Adhé.rencontre #5

For its 4th edition, the 72h de l'écologie returns from Friday 2 April to Sunday 4 April 2027, two weeks before the first round of the presidential election!

To bring ideas together, create partnerships and build the 2027 program together, the Cité des Transitions invites its members and organizations interested in joining the network to a morning of collaborative festival planning.

This collaborative planning session is an important opportunity to:

• Share and agree together on the main themes for the 2027 edition and the framework for the program

• Share your ideas and interests, showcase your initiatives and help shape an edition that reflects you

• Imagine themed routes connecting events and making it easier for the public to take part

• Meet other local organizations to identify complementarities, foster partnerships and develop joint events

• Think about an edition that reaches new audiences, goes beyond the usual circles and encourages people to get involved

• Strengthen connections across the network and join a collective effort in support of ecological and social transitions.

Please note: this year, we will limit the number of events in the program and, when selecting proposals, give priority to organizations that take part in the collective process and attend this collaborative planning session.

Previous editions have shown that participants greatly value these collective-intelligence sessions, as they help generate joint events and new collaborations.

Coordinated by the Cité des Transitions with its entire network, the 72h de l’écologie is a three-day festival that shines a spotlight on sustainable and community-minded initiatives in the area, encourages people to connect and inspires them to take action. A wide range of events (workshops, talks, tours, performances, unusual experiences...) are offered by people working for ecological and social transitions in the area.

Organized by: Cité des Transitions

The Cité des Transitions acts as a network bringing together stakeholders committed to ecological, social and economic transitions. It works to promote local initiatives, identify needs and propose appropriate solutions. By encouraging cooperation and coordinating a network of landmark venues based on the “15-minute city” concept, it mobilizes positive energy and highlights local successes to inspire others to replicate them.

Drawing on the doughnut model, the Cité des Transitions promotes an equitable and sustainable transition. It identifies strategic venues across Marseille’s neighborhoods, chosen for their strong local roots, and serves as a resource center for those working on the transition.
