President Masoud Pezeshkian said Iran must relocate its capital from Tehran because of worsening water shortages and land subsidence, calling the shift an “obligation” as parts of the metropolis sink by as much as 30 centimeters a year.
Tehran, Iran’s political and demographic center, is straining under water depletion, land subsidence and aging infrastructure. In remarks carried by state-linked media, President Masoud Pezeshkian warned the situation is a “catastrophe” driven by decades of mismanagement, construction in upstream areas and reduced downstream flows. He said water resources no longer match demand, making further population or construction growth impossible, and warned that staying put would mean “signing our own destruction.” “We no longer have a choice; it is an obligation,” he said.

Officials are again studying relocation to the Makran coast on the Gulf of Oman, a sparsely developed region touted for access to open waters but flagged for security, climatic and cost challenges. Past relocation pushes since the 1979 revolution stalled over political resistance and price tags running into the tens of billions of dollars; a former interior minister estimated around $100 billion.

The environmental pressures are acute. Authorities this month warned of water rationing—and even a contingency evacuation—if rains fail by late November, with reservoirs that feed the capital at their lowest in decades. Independent reporting has described this as Iran’s worst drought in roughly six decades. (apnews.com)
Land subsidence compounds the risk. Researchers and officials have documented annual sinking rates in and around Tehran that can exceed 25 centimeters, with even higher rates in other parts of the country due to aggressive groundwater extraction. Pezeshkian has cited figures of up to 30 centimeters a year in parts of the capital. (sciencedaily.com)
Israel’s water strategy is often cited as a counterpoint. Large-scale reverse‑osmosis desalination now provides a majority share of Israel’s drinking water—about 60% to 80% in recent years—while the country reuses roughly 85%–90% of its treated wastewater, the highest rate globally, much of it for agriculture. A national grid allows water to be moved where needed. (timesofisrael.com)
Israel also inaugurated, in December 2022, a project that enables pumping desalinated Mediterranean seawater into the Sea of Galilee via the Tzalmon stream—an infrastructure step designed to stabilize levels in the national lake and bolster overall system resilience. (timesofisrael.com)
Offers of assistance to Iranians predate the current crisis. In June 2018, Prime Minister Benjamin Netanyahu released a video proposing to share Israeli know‑how with the Iranian public, including a Persian‑language website on water recycling and irrigation. In that message he quoted Iranian data that nearly 96% of the country was experiencing some level of drought and cited a former Iranian agriculture minister’s earlier warning that up to 50 million people could eventually be displaced by environmental damage.

While Pezeshkian frames relocation as unavoidable, experts caution that moving a capital would be extraordinarily complex and would not by itself fix Tehran’s underlying water and land‑use problems. Analysts and local media note the need for systemic reforms—particularly in agriculture and industry—to curb demand and stabilize aquifers. (ft.com)
