Science at theUM [S05-ep13]: Iran on a Drought Diet
This week on *A l’UM * Science, Séverin Pistre, a researcher at Hydrosciences Montpellier , talks to us about the looming water crisis in Iran caused by mismanagement by the mullahs’ regime. Nathan Roure invites you to the 2026 edition of the “My Thesis in 180 Seconds” competition. The show airs every Wednesday on Divergence.

In 2022, the Iranian people took to the streets chanting “Woman, life, freedom.” This slogan could very soon become “Woman, life, freedom, and water,” as this resource is becoming increasingly scarce in this Gulf nation. Scientists are trying to raise awareness about this situation, but it is difficult at present to make their voices heard when the sound of bombs drowns out everything else.
The problem, however, is not new; it dates back to the aftermath of the Islamic Revolution in 1979, when the mullahs’ regime enshrined the goal of national food self-sufficiency in the Constitution. This goal—which the ministry, renamed the Ministry of Agricultural Jihad, has never achieved—will come at the cost of the wasteful management of groundwater reserves.
Iran is not an isolated case; it is estimated that 60 percent of the world’s population lives in regions that are expected to experience water shortages and a reduction in surface water availability by 2050, but the intensity of the war is once again shining a spotlight on these geostrategic issues, which are particularly concentrated in the Persian Gulf.
In Montpellier, Séverin Pistre, a hydrologist at Hydrosciences Montpellier, recently reminded us of this in an interview with the newspaper *Le Point* on March 15. In it, he discusses the water crisis as well as the difficulty of contacting students currently in Iran and the exile of his colleague Roohollah Noori, with whom he published an article in *Nature Communications* in 2023 titled “The Decline in Groundwater Recharge in Iran”.
At the end of the program, Nathan Roure from the communications department of theUM invites you to the local finals of the MT 180 contest, which will take place on April 2 from 6:00 p.m. to 8:00 p.m. in Nîmes.
