China has a long history of taming its rivers—efforts that trace back to the ancient Xia dynasty. However, in the age of Artificial Intelligence, China faces a modern challenge: cities are sinking. A conflux of factors, including excessive groundwater extraction and towering skyscraper construction, is causing notable land subsidence in Chinese metropolises.
Research Indicates Sharp Decline in Urban Elevations
Recent studies by Beijing University and the Chinese Academy of Sciences reveal a stark picture of urban China: within 100 years, about 26% of its territory could be underwater. It is reported that China’s major cities are subsiding by over 10 millimeters annually, a trend if continued, could displace significant populations and disrupt national infrastructure. Experts point to the excessive use of groundwater and the weight of rapidly constructed high-rises as culprit behind this sinkage.
Industrial Water Usage and AI’s Thirst Compounding Issues
The problem isn’t solely due to land mismanagement; it interlinks with other sectors. China’s reliance on coal and the surge in its semiconductor and AI industries are driving up water consumption. Facilities that cool down the massive heat generated by AI systems, particularly data centers, are adding to China’s water woes. It’s estimated that Chinese data centers might consume water exceeding the usage of a country like South Korea by 2030, placing further strain on already limited water resources.
Facing the Crisis: China’s Counter Measures
In response, China has begun instituting policies aimed at curbing water usage, and exploring innovative solutions like submersing data centers in ocean nearby Hainan Island—a project that could save substantial amounts of electricity and water. Moreover, new regulations set to take effect in May encourage the development and wide application of water-saving technologies, fostering a market for innovation in water conservation.
Key Questions and Answers on China’s Urban Sinking Challenge:
1. What is urban land subsidence and how is it measured?
Urban land subsidence refers to the gradual sinking of land in urban areas, often measured through geodetic surveys, GPS data, and satellite observations like InSAR (Interferometric Synthetic Aperture Radar).
2. Why are Chinese cities particularly prone to sinking?
Chinese cities are prone to sinking due to factors such as intensive groundwater extraction to support urban populations and industrial activity, along with the weight of numerous, densely packed high-rise buildings.
3. What are the potential impacts of land subsidence?
Land subsidence can lead to increased flood risk, damage to buildings and infrastructure, tilting of structures, and disruptions to underground utilities. Ecologically, it can also affect river flows and groundwater levels.
4. Are there historical precedents for the current situation in China?
Historical precedents exist in various forms globally, for example, Mexico City and Venice have both faced significant sinking due to similar issues, but China’s rapid urbanization amplifies the challenge.
Key Challenges and Controversies:
– Monitoring: Developing comprehensive monitoring systems to continuously track sinking rates and pinpoint risk areas.
– Regulation: Attention to potential conflicts between economic growth and stringent regulations aimed at decreasing water use and mitigating sinking.
– Adaptation: Crafting long-term strategies to adapt urban infrastructure for resilience against subsidence.
Advantages and Disadvantages of Current Countermeasures:
Advantages:
– Innovative solutions like submersed data centers could provide energy and water efficiency.
– Water-saving technologies can save costs and conserve vital resources for future generations.
Disadvantages:
– The cost of innovation and infrastructure retrofitting can be high.
– Regulations might be challenging to enforce and could face resistance from industries dependent on heavy water use.
