Tehran is running out of water.\u00a0<\/p>\n

Rationing has begun<\/a> in Iran\u2019s capital city, with some of the approximately 10 million residents experiencing \u201cnightly pressure cuts<\/a>\u201d\u00a0 between midnight and 5 am. The entire country is in an unprecedented drought, facing<\/a> its driest \u2014 and hottest \u2014 autumn in nearly 60 years. Tehran has received<\/a> no rain at all since the start of September, and no rainfall is expected for the foreseeable future.<\/p>\n

The city depends<\/a> on five major reservoirs for its water supply. One has dried up completely, with another below 8 percent capacity. The managing director of the Tehran Regional Water Authority told state media last week that the Karaj Dam has only two weeks of drinking water left. The drought extends beyond the city, too. The water reserves of Mashhad, the second largest city in the country, have dropped<\/a> below 3 percent capacity, putting 4 million people at imminent risk.\u00a0<\/p>\n

But if nothing changes, Tehran may soon face Day Zero<\/a> \u2014 or when a municipality can no longer supply drinking water to its residents and taps run dry. In October, President Masoud Pezeshkian claimed<\/a> that Tehran could no longer serve as the country\u2019s capital, citing the water crisis as a major factor. <\/p>\n

“If it doesn’t rain in Tehran by late November, we’ll have to [formally] ration water,\u201d Pezeshkian told<\/a> Iranian state media on Thursday. \u201cAnd if it still doesn’t rain, we’ll have to evacuate Tehran.”<\/p>\n

While it\u2019s unlikely evacuation will happen any time soon, Tehran\u2019s water crisis is not made equal. When the taps run dry, more affluent Tehranis purchase<\/a> mineral water or rely on water tankers, a prohibitively expensive option for many. The rest must rely on charity, or they will die of thirst.<\/p>\n

How did things get this dire?<\/h2>\n

Water use in Tehran is quite high<\/a>, even for cities. But Iran\u2019s water problems go deeper than this record-breaking drought.\u00a0<\/p>\n

The country is uniquely isolated and subject to numerous sanctions, crippling the economy and making it very difficult for Iran to obtain state-of-the-art water technologies. It\u2019s an enemy state to many of its neighbors<\/a>, as well as regional leaders in desalination technology \u2014 Israel<\/a>, Saudi Arabia<\/a>, and the United Arab Emirates<\/a>. But desalination is largely irrelevant<\/a> in an Iranian context, often coming at a high environmental cost<\/a>.\u00a0<\/p>\n

According to water issues analyst Nik Kowser, Iranians are under the thumb of a \u201cwater mafia<\/a>\u201d \u2014 a shadowy and well-connected network driving these megaprojects for their own gain. \u201cIran faces water bankruptcy, with demand far outstripping supply,\u201d Kowsar wrote<\/a> in Time. \u201cThe collapse of water security in Iran has been decades in the making and is rooted in a mania for megaprojects \u2014 dam building, deep wells, and water transfer schemes \u2014 that ignored the fundamentals of hydrology and ecological balance.\u201d\u00a0<\/p>\n

Iran is also particularly vulnerable<\/a> to the effects of climate change: Over 82 percent of the country is arid or semi-arid, and Iran is sixth on the list of countries most prone to natural disasters. The country grows thirsty crops, and its quest for food security and self-sufficiency is a tremendous driver<\/a> of its water bankruptcy. The agricultural sector comprises<\/a> up to 90 percent of the country\u2019s total water withdrawals.\u00a0<\/p>\n

But Iran\u2019s environmental crisis does strain existing geopolitical tensions both inside and outside of the country. Water is sometimes transported from one region of the country to supply another, driving fears that certain ethnic populations are intentionally being deprived at the expense of others.\u00a0<\/p>\n

Yale University historian and Iran expert Arash Azizi<\/a>, who is also a contributing writer for The Atlantic, told me that despite the tremendous humanitarian cost of continued sanctions, they are very unlikely to be removed in response to the water crisis.\u00a0<\/p>\n

The future of urban living<\/h2>\n

Tehran joins many, many other cities that have approached Day Zero, and it certainly will not be the last. S\u00e3o Paulo in Brazil and Cape Town, South Africa, had similar crises that ended<\/a> with rainfall. Tehran might not be so lucky in terms of its weather forecast, though.\u00a0<\/p>\n

So, let\u2019s loop back to the idea of evacuating Tehran.<\/p>\n

It is, of course, incredibly unpopular. Iranians balked at the idea when the president mentioned the possibility. Former Tehran Mayor Gholamhossein Karbaschi said<\/a> this was \u201ca joke\u2026 Evacuating Tehran makes no sense at all.\u201d\u00a0<\/p>\n

Azizi thinks it\u2019s unlikely that Iran will end up moving its capital anytime soon. The majority of jobs are in Tehran. And evacuating a city of upward of 10 million people would be an incredible logistical challenge.\u00a0<\/p>\n

More importantly, relocation won\u2019t fix the immediate issue of water access. But the current strategy of trucking in supplies, rationing water, and praying for rain is woefully inadequate to meet the moment. And water rationing is a stopgap measure.\u00a0<\/p>\n

\u201cActually cutting off the supply to households or to individual neighborhoods de facto reduces their consumption,\u201d said David Michel, senior fellow for water security at the Center for Strategic and International Studies. \u201cBut the underlying demand is still there.\u201d<\/p>\n

However, there are other kinds of strategies cities like Tehran could employ. Michel argued that cities have to prioritize business models that provide the resources and revenues needed for water systems to operate, maintain, and expand to serve new customers.<\/p>\n

\u201cThat challenge has put many city water systems around the world into this very challenging spiral where lots of municipal water systems\u2019 revenues don’t cover the costs of operations and maintenance, much less expanding supply,\u201d Michel said. Economic incentives like volumetric tariffs<\/a>, where the cost of water is proportional to the amount consumed, could be beneficial. The more you use, the higher price you pay, essentially, with the hope of reducing pressure on the poorest consumers.<\/p>\n

Relief can\u2019t come to Tehran soon enough. American cities in California and the southwest, with similarly arid climates and dwindling water supplies, should take heed. And everyone should pay attention when the president of Iran says the residents of its capital city may have to evacuate in a few months\u2019 time.\u00a0<\/p>\n

\u201cYou can imagine the psychological effect,\u201d Azizi said. And that could be \u201cthe future of everywhere in the world.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
