伊朗总统再谈“迁都”：缺水危机加剧，别无选择

Core Viewpoint - The Iranian President, Pezeshkian, announced the necessity of relocating the capital from Tehran to the southern region of the country due to severe urban expansion, worsening water shortages, and increasing ground subsidence threats [1][3]. Group 1: Urban Expansion and Water Crisis - Pezeshkian emphasized that the current resource crisis in Iran is urgent, necessitating the relocation of the capital, despite previous criticisms of such proposals [3]. - Tehran, Karaj, and Qazvin are currently facing a severe water crisis, which is not easily resolvable [3]. - The region of Hormozgan, located along the Persian Gulf, is seen as a more viable option for relocation due to better access to water resources and trade opportunities [3]. Group 2: Climate and Environmental Challenges - The rainfall in Iran has significantly decreased, with last year's rainfall recorded at 140 mm, compared to a standard of 260 mm, indicating a decline of approximately 50% to 60% [5][6]. - Ground subsidence in Tehran is alarming, with some areas sinking by 30 cm annually, indicating a critical depletion of water resources [6]. - Tehran's population exceeds 10 million, consuming nearly one-quarter of Iran's total water resources, exacerbating the water crisis [6]. Group 3: Historical Context and Future Planning - Iran has been exploring the idea of relocating the capital to the Persian Gulf coast for a long time, as water supply issues are less severe in that region [6]. - Pezeshkian is the first Iranian president to view the relocation of the capital as an unavoidable choice, highlighting the urgency of the situation [6].
