CGWB has found that between 2011 and 2020, about 70% of wells have registered a rise in water level whereas about 30% of the wells monitored have registered a decline in groundwater level mostly in the range of 0–2 m.

Reasons for Groundwater Depletion: Continuous withdrawal is necessitated by increased demand for freshwater for various uses, unpredictability in rainfall, increased population, industrialization & urbanization etc.

Note: Water being a State subject, sustainable groundwater management including initiating suitable action for effective rainwater harvesting, increasing water use efficiency etc falls under the state’s mandate.
