India: The Indian Institute of Remote Sensing has signed a Memorandum of Understanding (MoU) with Central Ground Water Board to facilitate a collaborative study to assess the impact of ground water abstraction on land subsidence in Northern India. The study involves application of state-of-art technologies such as Space-borne geodetic observations on land subsidence, predictive modelling, inter-comparison of land subsidence, ground water depletion and space-based gravity anomaly etc. Deliverables include land subsidence information for selected cities of northern India and regional groundwater depletion scenario along with recharge assessment.
The study will be first-of-its-kind in India and will have a great significance in identification of hotspots affected by over exploitation of ground water said Shri Sushil Gupta, Chairman, Central Ground Water Board.
