Like many countries, Iran has struggled with major water scarcity in recent years. Last summer its capital, Tehran, came very close to “day zero,” the day when the whole city runs out of drinking water. Now, with the United States at war with Iran, President Donald Trump has further threatened the country’s civilian water infrastructure, including dams, water treatment plants, and the electrical grid.Dr. Kaveh Madani is a water scientist and the former Deputy Head of the Department of Environment in Iran. He now leads the United Nations University Institute for Water, Environment and Health. He joins us to talk about his work on the concept of ‘water bankruptcy,’ his experience working on environmental issues in Iran, and the links between water and conflict.Threshold is nonprofit, listener-supported, and independently produced.
