How Beijing Restored Its Aquifer and Reversed Its Groundwater Depletion

Beijing's water table had dropped more than 20 meters by 2000, its aquifer drained like a savings account with no deposits-until the city proved that groundwater depletion can be reversed. By channeling water from wetter southern regions, expanding reclaimed water use for environmental purposes, and banning deep aquifer pumping for industry, the megacity brought dried springs back to life within a decade. "Groundwater depletion is not inevitable," says Professor Scott Jasechko, whose research reveals that recovery strategies vary widely-Green Bay needed two pipelines over 50 years to restore its aquifer, while Beijing's combined approach worked faster. The lesson isn't that solutions are simple, but that "the menu of strategies is longer than I anticipated," offering hope that careful intervention can refill what seemed permanently emptied.
