The Namami Gange Programme is implemented by which body?
- A.Central Pollution Control Board
- B.National Mission for Clean Ganga
- C.Central Water Commission
- D.NITI Aayog
Correct answer
Explanation
The correct answer is B, the National Mission for Clean Ganga. The mission, working under the Ministry of Jal Shakti, is the implementing agency of the Namami Gange Programme launched in 2014, and it works through State Ganga Committees and district committees along the river. Option A is wrong because the Central Pollution Control Board, created by the Water Act of 1974, sets and enforces pollution standards and monitors water quality, but it does not run the programme. Option C is wrong because the Central Water Commission deals with water resources development, flood forecasting and dam safety. Option D is wrong because NITI Aayog is a policy think tank without executive responsibility for such a mission. The programme covers sewage treatment, river surface cleaning, industrial effluent monitoring, afforestation, biodiversity and Ganga Grams.
