Jakarta’s sinking problem began in the 1970s and ties in directly with the number of groundwater extraction wells drilled during the period. : Floods in South Jakarta by Voice of America is available at https://bit.ly/3AXvSgI CC-BY-SA-3.0

Deep groundwater extraction wells are built by the business elites for commercial value. Better transparency will help manage them more sustainably.
