Context:

Recently, Geological Survey of India (GSI) celebrated its 174th Foundation Day on 4th March, 2024.

About Geological Survey of India (GSI): Geological Treasures of the Nation Since 1851

The Geological Survey of India (GSI) is a scientific agency under the Ministry of Mines, responsible for conducting geological surveys and studies of India. It is one of the oldest of such organisations in the world and the second oldest survey in India after the Survey of India (founded in 1767).

• Nodal Ministry: Geological Survey of India is an attached office to the Ministry of Mines.
• Origin: The Geological Survey of India was founded in 1851 by the East India Company, primarily to find coal deposits for the railways.
  • First geological surveyor of GSI was David Hiram Williams.
  • First director-general of GSI was Sir Thomas Oldham. He broadened the scope of the survey by mapping the rock types, geological structures and relative ages of different rock formations.
• Headquarter: Kolkata and has six regional offices located at Lucknow, Jaipur, Nagpur, Hyderabad, Shillong and Kolkata. 
  • Every state has a state unit.

The Geological Survey of India’s Functions and Activities: Mapping, Protecting, and Innovating for Earth’s Future

• Geological Mapping: The Geological Survey of India conducts comprehensive geological surveys and mapping exercises to create detailed maps of India’s geological formations, aiding in mineral exploration and resource assessment.
• Mineral Exploration: Through systematic exploration programs, the Geological Survey of India identifies and evaluates mineral deposits, contributing to the development of the mining sector and supporting industrial growth.
• Environmental Impact Studies: The Geological Survey of India conducts environmental impact assessments (EIAs) to evaluate the potential environmental effects of mining and infrastructure projects, ensuring sustainable development practices.
• Hazard Assessment: Leveraging its expertise in geology and seismology, the Geological Survey of India assesses natural hazards such as earthquakes, landslides, and floods, providing critical data for disaster preparedness and mitigation.
• Contribution to Natural Resource Management: Fuelling Economic Growth
  • Mineral Resource Assessment: The Geological Survey of India plays a pivotal role in assessing India’s mineral wealth, including coal, iron ore, bauxite, and precious metals, contributing to the country’s industrial and economic growth.
  • Groundwater Management: Through hydrogeological studies and groundwater prospecting, the Geological Survey of India supports sustainable groundwater management, addressing water scarcity and ensuring water security.
• Role in Environmental Protection: Safeguarding Environments
  • Environmental Impact Assessments (EIAs): The Geological Survey of India conducts EIAs to evaluate the environmental consequences of mining activities, guiding decision-making and promoting environmentally responsible practices.
  • Biodiversity Conservation: The organization’s geological studies contribute to the conservation of biodiversity by identifying ecologically sensitive areas and promoting habitat preservation.
• Disaster Mitigation and Risk Management:
  • Earthquake Hazard Assessment: Leveraging its expertise in seismology, the Geological Survey of India assesses earthquake risks and provides early warning systems, enhancing disaster preparedness and response.
  • Landslide Mapping: The organization conducts landslide mapping and risk assessments to identify vulnerable areas and mitigate landslide hazards, protecting lives and infrastructure.
• Research and Innovation:
  • Geological Research: The Geological Survey of India conducts cutting-edge research in geology, mineralogy, and geophysics, contributing to scientific knowledge and innovation in the field of earth sciences.
  • Technology Innovation: The organization leverages emerging technologies such as remote sensing, GIS, and geospatial analysis to enhance geological mapping and mineral exploration efforts.
• Outreach and Education:
  • Public Awareness Campaigns: The Geological Survey of India conducts public awareness campaigns, workshops, and seminars to educate stakeholders about geological processes, mineral resources, and environmental conservation.
  • Capacity Building: The organization offers training programs and workshops to build the capacity of professionals in the field of geosciences, fostering scientific literacy and promoting careers in geology.
