Land subsidence in Iran is increasingly concerning, impacting over 254 areas, especially in Kerman, Khorasan Razavi, and Tehran, where ground sinking poses risks to infrastructure and the environment. Factors such as rapid urbanization, climate change, and over-extraction of groundwater contribute to this issue. Tehran, home to over 15 million residents, faces alarming subsidence rates, with some areas sinking up to 31 centimeters annually. The severe decline in water resources, exacerbated by decreased rainfall, has prompted calls for immediate reforms in water management. Experts recommend reducing water use and improving efficiency to mitigate these challenges and protect vital infrastructures.
