# Science Fun: From water science to still photographs from schools in the 1950s

Welcome to La science s’aMuse, the science program co-produced by UM and Divergence-FM, which takes you on a cruise through the Muse laboratory archipelago. This week, Eric Servat, hydrologist and director of the UNESCO center dedicated to water, Icireward, alerts us to the urgent need to take action to prevent a global water shortage. In the second part of the program, Sylvain Wagnon, director of Cedrhe, introduces us to a surprising collection: still films.

This week, our scientific cruise invites you to return to our roots... While we still can! According to the OECD, 40% of the world's population will face water shortages by 2050. A crisis that, according to the Global Water Institute, could cause the displacement of 700 million people by 2030. Faced with this threat and without decisive global and local action, our beautiful cruise ship could well turn into a raft of the Medusa. On May 6, water scientists and members of parliament sounded the alarm by publishing an op-ed in the newspaper Le Monde entitled: "Without decisive action, there will be no solution to chronic water shortages." Our guest today is Eric Servat. He is a hydrologist and one of the signatories of this opinion piece. He will also talk to us about the research areas ofIcireward, the UNESCO center dedicated to water, which opened its doors in Montpellier last October and of which he is the director.

In the second part of the program, the report En salle des machines returns and takes you to the Faculty of Education in Montpellier, specifically to Cedrhe, the center for studies, documentation, and research in the history of education. Its director, Sylvain Wagnon, and Tatiana Tessier, a documentalist, preserve an incredible collection there: still films. Used as teaching materials in schools in the 1950s and 1960s, they bear witness to the evolution of teaching practices as well as the evolution of our society as a whole.

Cedrhe has a collection of 4,000 still films.
