- UNESCO Global Geoparks give local people a sense of pride in their region and strengthen their identification with the area.
- The creation of innovative local enterprises, new jobs and high quality training courses is stimulated as new sources of revenue are generated through sustainable geo tourism, while the geological resources of the area are protected.
- This bottom-up approach is becoming increasingly popular through the positive and effective running of the Global Geoparks Network (GGN) under UNESCO’s ad hoc support with individual Member States as appropriate.
- UNESCO’s work with Geo parks began in 2001.
- The Geological Survey of India (GSI) is an organisation under Ministry of Mines.
- It is founded in 1851 by East India Company.
