Mexico City, one of the largest urban centers globally, is facing a severe sinking crisis, with parts of the city subsiding by several centimeters each year. This issue stems from its construction on the ruins of Tenochtitlan, a city built on soft, waterlogged clay after the Spanish drained much of the surrounding lake in the 16th century. The extraction of groundwater to meet the demands of the growing population has led to the compression of this clay, resulting in irreversible ground sinking, known as subsidence. The consequences are visible throughout the city, with buildings tilting, roads cracking, and infrastructure becoming increasingly difficult to maintain. Additionally, the sinking exacerbates flooding risks, as the city's drainage systems struggle to manage water flow, particularly during heavy rains. Despite these challenges, Mexico City continues to function, and efforts are being made to promote sustainable water management to mitigate further damage.
