GIS technology to strengthen Namami Gange Programme

Why in News?

National Mission for Clean Ganga has brought on board Survey of India,  to facilitate the Ganga rejuvenation task by using Geographic Information System (GIS) technology.



About the Project

i)Through the project NMCG aims to strengthen planning and implementation at national/state/local levels.


ii)The project includes the use of Digital Elevation Model (DEM) technology which ensures accurate data collection, an important aspect of river basin management planning.


NOTE4STUDENTS-DEM technology enables identification of entire topography of an area making it easy for policy makers to analyse the available data thereby supporting the decision-making process. Critical hotspots are also easily identified through this technology.


iii)The use of GIS technology for Namami Gange programme will also ensure decentralisation. The data collected and subsequent actions taken by the government can easily be shared with the local public through geo portals and mobile apps.

iv)For effective discharge management, outlet of sewerage and other discharges from all units – industrial, commercial and all types of other institutions will be mapped from the source outlet to the public drainage network.


National Mission For Clean Ganga

National Mission for Clean Ganga(NMCG) was registered as a society under the Societies Registration Act 1860. It acted as implementation arm of National Ganga River Basin Authority(NGRBA) which was constituted under the provisions of the Environment (Protection) Act (EPA),1986. NGRBA has since been dissolved, consequent to the constitution of National Council for Rejuvenation, Protection and Management of River Ganga (referred as National Ganga Council).

The Act envisages five-tier structure at national, state and district level to take measures for prevention, control and abatement of environmental pollution in river Ganga and to ensure the continuous adequate flow of water so as to rejuvenate the river Ganga as below-

  1. National Ganga Council under the chairmanship of Prime Minister of India.
  2. Empowered Task Force (ETF) on river Ganga under the chairmanship of Union Minister of Water Resources, River Development and Ganga Rejuvenation.
  3. National Mission for Clean Ganga(NMCG).
  4. State Ganga Committees and
  5. District Ganga Committees in every specified district abutting river Ganga and its tributaries in the states.

NMCG has a two-tier management structure and comprises of Governing Council and Executive Committee. Both of them are headed by Director General, NMCG.
