Iran is facing its most severe water crisis in more than six decades.
Major dams supplying drinking water to provinces with millions of residents are nearly empty, and groundwater reserves have been depleted. Many cities have endured an entire autumn without a single drop of rain.
In the capital, Tehran, and in Mashhad, the country’s second-largest city, in the north-east, some reservoirs are at less than 5% and 3% capacity, respectively.
