• India being the largest consumer of groundwater accounting a major chunk i.e around 25% of the total world’s groundwater withdrawal which indicates a great dependency on it, and so its depletion will lead to various problems, as megacities like Bangalore and delhi are facing major shortage of water problem because a large chunk of population there depends on it.
• Reasonsof groundwater depletion in exacerbating  water crisis is as follows
• As the aquifers are not getting recharged properly due to the concretization in megacities which is being the major cause of water crisis

As the megacities cater a lot ofor population so over consumption is also there

• Due to the deforestation in the megacities,the groundwater is not getting recharged as its depleting
• Wetlands encroachments
• No strict conservation policies of water recharging
• Climate change is also exacerbating this crisis as high temperature are responsible for more evaporation
• Way forward 
• A stringent policy should be there for the overall recharging of the aquifers through promising methods like rainwater harvesting and various traditional methods
• Community awareness campaign can play a major role in generating awareness
• Wetlands conservation programme should be there
• Sustainable use of groundwater resources should be encouraged
• Being the largest consumer and catering the largest population of the world we should think of this challenging problem and implement the strategic management of not only the groundwater but all sources of water.
