# La Science s'aMuse: From water science to 1950s school film stills

Welcome to La science s'aMuse, the scientific program co-produced by the UM and Divergence-FM, which takes you on a cruise through the archipelago of Muse laboratories. This week, Eric Servat, hydrologist and director of the Unesco water center Icireward, alerts us to the urgent need to act to prevent a global water shortage. In the second half of the program, Sylvain Wagnon, director of Cedrhe, introduces us to a surprising collection of still films.

This week, our science cruise invites you to get back to basics... while we still can! According to the OECD, 40% of the world's population will face water shortages by 2050. A crisis which, according to the Global Water Institute, could displace 700 million people by 2030. Faced with this threat, and without decisive global and local action, our pretty cruise ship could well turn into a jellyfish raft. On May 6, water scientists and members of parliament sounded the alarm by publishing an article in Le Monde entitled: " Without decisive action, there will be no solution to the chronic shortage of water ". Our guest today is Eric Servat. He is a hydrologist and one of the signatories of this tribune. He will also tell us about the research focuses 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 half of the program, the report En salle des machines returns and takes you to Montpellier's Faculty of Education, and more specifically to Cedrhe, the center for study, documentation and research in the history of education. Its director, Sylvain Wagnon, and documentalist Tatiana Tessier, preserve an incredible collection of still films. Used as teaching aids in the schools of the 50s and 60s, they bear as much witness to the evolution of teaching practices as to the evolution of our society as a whole.

Cedrhe has a collection of 4,000 still films
