ISRO-IIT Study Finds Rare Land Uplift in Dwarka, Signalling Groundwater Recovery
In a remarkable environmental turnaround, land in Delhi Dwarka once among the city most groundwater-stressed zones is rising again. A joint study by the Indian Space Research Organisation (ISRO), IIT Kanpur, IIT (ISM) Dhanbad, and the University of Miami has revealed that after years of gradual sinking, Dwarka’s land is now lifting, indicating groundwater replenishment.
The study, published in Water Resources Research and titled InSAR Reveals Recovery of Stressed Aquifer Systems in Parts of Delhi, India, analysed satellite data from October 2014 to October 2023. Researchers found that land subsidence in Dwarka has not only halted but reversed with certain areas lifting by 5 to 10 centimetres since 2016. The upward movement, averaging 2 cm per year across nearly 4 sq km, points to the sl...
