## ANSWER

## MINISTER FOR MINISTRY OF SCIENCE AND TECHNOLOGY AND

## MINISTRY EARTH SCIENCES (DR. HARSH VARDHAN)

- (a) & (b) Central  Ground  Water  Board  is  periodically  monitoring  the ground  water  levels  throughout  the  Country  on  a  regional scale, through a network of monitoring wells.

The Dynamic Ground Water Resources of the country are also being  periodically  assessed  jointly  by  Central  Ground  Water Board (CGWB) and State Governments.As per the 2017 assessment,  out  of  the  total  6881  assessment  units  (Block/ Taluks/  Mandals/  watersheds/  Firkas)  in  the  country,  1186 units in 17 States/UTs  have  been  categorized  as  'Overexploited'  where  the  total  Current  Annual  Ground  Water Extraction  is  more  than  Annual  Extractable  Ground  Water

Resource.

Central  Ground  Water  Board  is  implementing  a  nationwide programme  of  'National  Aquifer  Mapping  and  Management (NAQUIM)' for mapping of aquifers (Water bearing formations), their characterization and development of aquifer management  plans  to  facilitate  sustainable  development  of ground  water  resources.  So  far  about  1l  lakhs  sq.km  have been covered. Aquifer maps and management plans have been shared with the respective State Government agencies.Public Interaction  Programs are being organised at grass root level for disseminating the tenets of the Aquifer Management Plans for the benefit of the stakeholders.

The Research &Development Division, Project Planning Wing, Department  of Water Resources, River  Development  and Ganga Rejuvenation wing of Central Water Commission (CWC) have awarded studies on impact of climate change on water resources to some of the premier educational institutes. The studies are to be implemented under the supervision of Indian National Committee on Climate Change (INCCC).
