We are now in charge of an exceptional heritage: a lake whose state of health has improved but which is still fragile, subject to the effects of ongoing climate change and the growing pressure of human activities.
The work done by the CIPEL for decades is in this sense extremely valuable and it is important to continue it by adapting it to the new challenges that await us by 2030.
Mysterious immensity, majestic mirror, unchained soul... just a few words, and Lake Geneva is already alive! The CIPEL and the Musée du Léman invite you to a new Franco-Swiss writing project: "Les mots bleus du Léman". A platform offered to all those who want to write. Writing workshops, online writing games, to encourage literary creation, with respect for each person, without pretension or stakes. The only goals are to share and connect.
The CIPEL has just set up a nicely illustrated exhibition to raise public awareness of the preservation of the natural environments along Lake Geneva. The visitor is invited to discover the fauna and flora through 5 different distinctive environments.

The International Commission for the Protection of the Waters of Lake Geneva (CIPEL),
an intergovernmental Franco-Swiss body, has been contributing since 1963 to the coordination of water policy on the scale of the Lake Geneva basin, i.e. between France and Switzerland, and more particularly on the territories of the departments of Ain and Haute-Savoie as well as the cantons of Vaud, Valais and Geneva.
Its perimeter, covering an area of more than 10,000 km2 , covers the catchment area of the Lake Geneva and, more generally, of the Rhône upstream of the Franco-Swiss border.
