        "summary": "A study of 465 cities with populations above one million found that urban land subsidence varies widely worldwide but has generally slowed in recent years. The most severe subsidence was recorded in Southeast Asia, West-Central Asia and North America, while researchers say water allocation and groundwater management have helped curb the problem in parts of East and Southeast Asia.",
        "content": "<p>Beijing (ANTARA) \u2014 Global urban land subsidence varies considerably,\nbut has generally slowed in recent years, according to a study by a\nChinese research team published on 12 October in the journal Nature\nCities.<\/p>\n<p>Researchers from Peking University, South China Normal University and\nother institutions systematically assessed subsidence between 2014 and\n2023 in 465 cities worldwide, each with a population of more than one\nmillion.<\/p>\n<p>Land subsidence is a global problem that poses major challenges to\nthe safety of urban infrastructure and sustainable development.<\/p>\n<p>According to the study, the most severe subsidence occurred in\nSoutheast Asia, West-Central Asia and North America. Cities cited as\nexamples include Mexico City and Toluca in Mexico, and Medan and Bandung\nin Indonesia. Mexico City recorded the most intense local subsidence, at\na rate exceeding 0.2 metres a year.<\/p>\n<p>Although subsidence remains widespread, global urban subsidence has\ngenerally slowed in recent years. The research team detected a\nsignificant slowdown in many cities in Southeast and East Asia.<\/p>\n<p>This suggests that water allocation and groundwater-management\nmeasures in the two regions have been effective, said Hu Xie, a member\nof the research team at Peking University.<\/p>\n<p>\u201cIn particular, in China\u2019s Beijing-Tianjin-Hebei urban agglomeration,\nlarge-scale water-diversion projects such as the South-to-North Water\nDiversion Project, together with stronger groundwater management, have\nhelped replenish groundwater in some areas, significantly reducing\nsubsidence,\u201d Hu said.<\/p>\n<p>The team also developed an open platform for global urban land\nsubsidence, offering the public a searchable dataset in a visual\nformat.<\/p>\n<p>As geological and groundwater big data accumulate and artificial\nintelligence (AI) and complex models advance, analyses of the causes of\nsubsidence and risk assessments will have a stronger data and\nmethodological foundation, said Tao Shengli, a researcher at Peking\nUniversity.<\/p>",
