New satellite-based research has identified signs of Ahmedabad land subsidence across parts of the city’s western and southern urban corridors, raising concerns over groundwater management, urban planning and the long-term resilience of rapidly expanding neighbourhoods.
[...]
The analysis, conducted using Interferometric Synthetic Aperture Radar (InSAR) technology and satellite observations collected between 2016 and 2025, detected measurable downward ground movement in several localities.

Even gradual ground movement can affect roads, drainage systems, underground utilities and building foundations over time, especially if development is not supported by continuous geotechnical monitoring and sustainable groundwater management.

The researchers emphasised that the current findings represent an interim assessment based on selected satellite processing periods and that analysis of the complete dataset is still underway.
