Iran's continued drought

At the end of 2025, Iran is facing yet another immensely threatening crisis amid historic drought: lack of water for its population of more than 90 million.

Rainfall has been at record lows, causing reservoirs to be nearly empty, in an already arid Middle East climate. The situation has grown so acute that President Masoud Pezeshkian has warned that if the drought persists for another month, Tehran's water would have to be rationed. But this appears to be happening currently, as no rain is expected for at least the next ten days.

Already Iranians are being urged to conserve water and only use what's available for the most pressing needs. Pezeshkian has actually said something stunning and unprecedented on Monday, though some are describing it as obvious hyperbole: "If rationing doesn't work," Pezeshkian said, "we may have to evacuate Tehran."

The alarming statement resulted in an avalanche of criticism in Iranian media, also with former Tehran mayor Gholamhossein Karbaschi dismissing the idea as "a joke" and saying that "evacuating Tehran makes no sense at all".

Some regional analysts and officials report an over 90% decrease in rainfall compared with last year. The New York Times summarized just how dire the situation is: Iran’s officials have begun rationing water in the capital, Tehran, amid a drought so severe that the president has warned the capital may need to be evacuated.

The country is facing the worst drought in six decades, and major dams are at critically low levels. Water authorities this week said the main dams feeding Tehran, on which more than 10 million people depend, were at just 5 percent capacity.

On Sunday, the spokesman for Iran’s water industry, Isa Bozorgzadeh, told reporters that water pressure would be lowered from midnight until the morning “so that we can both reduce urban leakage and create an opportunity for city reservoirs to refill.”

Some people in Teheran have posted on social media saying that faucets in their homes have stopped producing water for hours at a time.

BBC wrote of one vital reservoir: "The manager of the Latian Dam, one of Tehran's main water sources, says it now holds less than 10% of its capacity. The nearby Karaj Dam — which supplies water to both Tehran and Alborz provinces — is in a similarly dire condition."

"I have never seen this dam so empty since I was born," one resident told Iranian state TV.

The macro problems of mismanagement and over-consumption are why Iran faces a general water crisis, but this current crunch has a very important climate element. There has been basically no rainfall in the central Iranian plateau for six months.
