Despite India being one of the countries of the Gondwanaland, its mining industry contributes much less to its Gross Domestic Product (GDP) in percentage. Discuss.

  • India being a part of Gondwanaland, is richly endowed with mineral wealth such as coal, iron, mica, aluminium etc., however, mining sector of India contributes only 2.2% to 2.5% to the GDP of the country. 
  • Reasons for low contribution are as under: Minerals are located in forested tribal areas. Democratic polity with a mandate for welfare creates conflicting priority of mineral exploitation and tribal development. 
  • Multiple clearances and Legal hurdles: The mining sector ails from the requirement of multiple clearances, which makes the sector unviable/unprofitable. For example, Environmental/forest clearances. The mining sector is also susceptible to various legal pronouncements. For example, SC judgement on coal block allocation affected coal mining output. 
  • High levies: Mining sector in India is subjected to much higher levies than other mining geographies. For example, high royalties, double taxation etc. Poor exploration: Highly restricted licensing regimes, disincentivises private players to indulge in mineral exploration. Monopoly of PSUs: Mining sector suffers from problem of unproductive usage of assets, due to monopoly of PSUs. For example, coal India’s monopoly in coal sector. 
  • Slow modernisation: India’s mining sector has been slow in adopting productive global trends. For example, smart mines etc. The mining sector of India, hold immense potential to reduce import dependence and hurl industrial development. In this light faster administrative clearances need to be ensured and security challenges like Naxalism etc., in the mining belt need to be checked.

FAQs on GS1 (Mains Answer Writing): Gondwanaland and Plate Tectonics - Geography for UPSC CSE

1. What is Gondwanaland and how does it relate to plate tectonics?
Ans. Gondwanaland was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It was formed when the earlier supercontinent, Pangaea, began to break apart around 200 million years ago. Gondwanaland consisted of present-day South America, Africa, Antarctica, India, and Australia. The breakup of Gondwanaland played a crucial role in the development of plate tectonics as it led to the separation of these land masses and the formation of the modern continents.
2. How do plate tectonics explain the movement of continents?
Ans. Plate tectonics is the scientific theory that describes the movement of Earth's lithosphere, which is divided into several large and small plates. These plates float on the underlying semi-fluid asthenosphere. The movement of these plates is driven by the convective currents in the Earth's mantle. The plates can move apart (divergent boundary), collide (convergent boundary), or slide past each other (transform boundary). The continents, which are part of these plates, are carried along with them during these plate movements, explaining the shifting of continents over millions of years.
3. What evidence supports the theory of plate tectonics?
Ans. Several lines of evidence support the theory of plate tectonics. Firstly, the fit of the continents is one key piece of evidence. The coastlines of South America and Africa fit together like puzzle pieces, indicating they were once joined. Secondly, the distribution of fossils and similar rock formations across continents supports the idea of past connections. For example, the presence of similar fossils in South America and Africa suggests they were once part of a larger landmass. Additionally, seismic activity and the occurrence of earthquakes and volcanic eruptions along plate boundaries provide further evidence for the movement of tectonic plates.
4. How does plate tectonics influence the Earth's surface features?
Ans. Plate tectonics is responsible for shaping the Earth's surface features. Convergent boundaries, where plates collide, can result in the formation of mountains, such as the Himalayas. Divergent boundaries, where plates move apart, lead to the creation of new crust through volcanic activity and the formation of mid-ocean ridges. Transform boundaries, where plates slide past each other, can cause earthquakes as the plates become locked and then suddenly release energy. Overall, plate tectonics is a fundamental process that drives the formation of mountains, ocean basins, and other geological features.
5. How does the theory of plate tectonics help in understanding natural hazards?
Ans. The theory of plate tectonics plays a crucial role in understanding and predicting natural hazards such as earthquakes, volcanic eruptions, and tsunamis. By studying plate boundaries and their interactions, scientists can identify areas that are prone to seismic activity. For example, subduction zones, where one plate is forced beneath another, are typically associated with strong earthquakes and volcanic eruptions. This knowledge helps in developing strategies for disaster preparedness, early warning systems, and designing buildings and infrastructure to withstand these hazards. Understanding plate tectonics is therefore essential for mitigating the risks associated with natural disasters.
