Iran’s capital Tehran is counting right down to “day zero” – the day the water runs out and the faucets run dry.
Reservoirs that offer Tehran’s 15 million residents are virtually empty.
The Karaj dam, which provides 1 / 4 of town’s ingesting water, is simply 8% full.
Water rationing has begun in some areas, with the stream from faucets lowered and even stopped altogether in a single day.
President Masoud Pezeshkian has urged individuals to make use of water sparingly – or town, or at the very least elements of it, might even need to evacuate.
So what is going on on?
Rain ought to begin falling within the autumn after Iran’s scorching dry summer time.
However in accordance with the nation’s Nationwide Climate Forecasting Centre, this has been the driest September to November interval in half a century, with rainfall 89% beneath the long-term common.
The mix of low rainfall and excessive warmth has lasted for greater than 5 years, leaving the nation parched.

However that places town in direct competitors with farmers who draw on the water to irrigate crops.
Ranges are falling by 101 million cubic metres a yr round Tehran, in accordance with evaluation within the journal Science Advances. That is water that has amassed from many many years of rain – and can take at the very least as lengthy to replenish.
Professor Kaveh Madani, the previous deputy head of Iran’s atmosphere division and now director of the United Nations College Institute for Water, Surroundings & Well being, mentioned persistent mismanagement of pure sources has led to what he calls water chapter.
“They’re the product of decades of bad management, lack of foresight, overreliance and false confidence in how much infrastructure and engineering projects can do in a country that is relatively water short.”
Authorities ministers blame the water scarcity on local weather change, water leaks from pipes and the 12-day conflict with Israel.
Regardless of the purpose, it underlines the specter of water shortage to world cities. Tehran isn’t alone.
