Answer 1

$\huge\boxed{\fcolorbox{cyan}{pink}{Answer}}$

❥Groundwater tables on the whole in India are stable but the situation in some states is grave, according to the Central Groundwater Board (CGWB)’s latest report. Most wells showed a decline in the level of groundwater.

❥Around 162.22 million cubic metres of water are still available for irrigation according to the Ground Water Year Book - India 2017-18.

❥This is the same as the last evaluation in 2016-17.

❥A comparison of groundwater levels in India pre-monsoon 2017 with the decadal mean of pre-monsoon (2007-2016), indicates that out of 14,465 wells analysed by the CGWB, around 61 per cent of wells show a decline in water levels.

❥More than 60 per cent of wells show a fall in groundwater levels in states and Union Territories (UTs) like Chandigarh, Punjab, Puducherry, Uttar Pradesh, Tamil Nadu, Andhra Pradesh, Dadra and Nagar Haveli, Haryana, Himachal Pradesh, Jammu and Kashmir, Karnataka, Kerala and Meghalaya.

❥Among the 16,078 wells monitored by the CGWB during pre-monsoon, the number of wells showing the depth of groundwater at more than 40 metres below ground level (mbgl) decreased by 49 in 2017-18 in comparison to 2016-17.

❥But, there are specific states where the number increased.
