What is groundwater depletion in India?

How Punjab can overcome the problem of lowering water table?
Converting 1% of wheat area (35,000 hectares) in a year on drip irrigation system under rice-wheat cropping system, can arrest the decline of groundwater by 3cm per year. There will be 40-50% water saving if the area under fruits, vegetables, sugarcane, and cotton are brought under the drip irrigation system.
