How much groundwater is depleted India?
The total estimated groundwater depletion in India is in the range of 122–199 billion metre cube.
What rate is the groundwater declining in India?
It has been reported that in many parts of the country the water table is declining at the rate of 1–2 m/year. At the same time in some canal commands, the water table rise is as high as 1 m/year. Deterioration in groundwater quality by various causes is another serious issue.
Is groundwater depleting in India?
This expansion has led to India becoming the largest consumer of groundwater worldwide and to severe groundwater depletion in many parts of the country.
What are the major causes of groundwater depletion in India?
Subsidies on electricity and high MSP for water intensive crops is also leading reasons for depletion. Water contamination as in the case of pollution by landfills, septic tanks, leaky underground gas tanks, and from overuse of fertilizers and pesticides lead to damage and depletion of groundwater resources.
What is the main reason for depletion of groundwater?
Groundwater depletion is primarily caused by sustained groundwater pumping. Some of the negative effects of groundwater depletion: drying up of wells. reduction of water in streams and lakes.
How much groundwater does India use?
The basic data points collected by the Indian government, and no longer veiled from public view, illustrate the widening emergency. India uses or consumes more than 600 billion cubic meters (158 trillion gallons) of water annually. Of that amount, 245 billion cubic meters are drawn from aquifers.
What is the situation of groundwater in India?
India is the largest user of groundwater in the world. It uses an estimated 230 cubic kilometers of groundwater per year – over a quarter of the global total. More than 60% of irrigated agriculture and 85% of drinking water supplies are dependent on groundwater.
Which regions in India are facing issues of groundwater depletion?
The Indo-Gangetic Plain, northwestern, central and western parts of India account for most intensive groundwater-based irrigation. And among these regions, western India and the Indo-Gangetic Plain have more than 90% of the area irrigated using groundwater.
What are the causes of groundwater depletion?
Causes of Groundwater Depletion
- Groundwater depletion most commonly occurs because of the frequent pumping of water from the ground.
- We continuously pump groundwater from aquifers and it does not have enough time to replenish itself.
- Agricultural needs require a large amount of groundwater.
What are the reasons for ground water depletion?
Stressors that can deplete aquifers include changes in precipitation and snowmelt patterns; withdrawal of ground water for drinking, irrigation, and other human uses; and impervious paved surfaces that prevent precipitation from recharging ground water.
How can we control groundwater depletion?
Ways to Protect and Conserve Groundwater
- Go Native. Use native plants in your landscape.
- Reduce Chemical Use.
- Manage Waste.
- Don’t Let It Run.
- Fix the Drip.
- Wash Smarter.
- Water Wisely.
- Reduce, Reuse, and Recycle.
How much water is wasted in India per year?
228 million litres of water goes down the drain everyday.
What is the percentage of groundwater in India?
Groundwater irrigation has been expanding at a very rapid pace in India since 1970s and now accounts for over 60 percent of the total area irrigated in the country. About 85% of the rural drinking water supply is also met from ground water sources.
What are the main groundwater quality problems in India?
Salinity, nitrate, Coliform & Fluoride are the main water quality issues in the metro cities and problem areas of the country. Considering the competing demand on this scarce resource, the Report highlights the judicious use of groundwater and also remedial measures needed to overcome the problems.
How can we prevent groundwater depletion?
What are 4 effects of groundwater depletion?
Some of the negative effects of ground-water depletion include increased pumping costs, deterioration of water quality, reduction of water in streams and lakes, or land subsidence. Such effects, while variable, happen to some degree with any ground-water use.
How can we reduce groundwater depletion?
Increasing supply of surface water and/or reducing demand of groundwater can reduce groundwater depletion to increase sustainability. Increasing water storage can help resolve the temporal disconnections between supply and demand.
What percentage of India’s water is wasted?
40 per cent of water supply gets wasted: Study.

What are the major causes of groundwater depletion?
Excessive pumping can overdraw the groundwater “bank account”
- drying up of wells.
- reduction of water in streams and lakes.
- deterioration of water quality.
- increased pumping costs.
- land subsidence.
What are 3 negative effects of groundwater depletion?
