“Water,” said Israel’s second prime minister Levi Eshkol, “is to the country like blood to a human being.” From the time of the Hebrew Bible and through the ages, Jews have prayed for water in the land of Israel, and when early Zionist leaders began building the institutions of statehood, they made water a central policy issue. In recent years, Israeli technology has effected a water revolution through desalinization, drip irrigation, and agricultural science. Now, the Jewish state's hydro-innovations have given it the diplomatic leverage to strengthen its friendships across the world.

On this week’s podcast, Seth Siegel, a water-technology expert, joins Mosaic editor Jonathan Silver to talk about Israel’s water revolution. Siegel is the chief sustainability officer at N-Drip, an Israeli hydro-technology company, and the author of the 2015 book Let There Be Water: Israel’s Solution for a Water Starved World. In this podcast, he talks about his work and about how this precious natural resource affects everything from Israeli utility bills to international diplomacy.
