Introduction
The tundra — Arctic, Alpine and Antarctic — occupies roughly a tenth of the earth's land surface. As the coldest of the world's climatic regions, it is defined by a growing season under three months, permafrost beneath the active layer, and vegetation limited to mosses, lichens, sedges and dwarf shrubs. The statement holds, but the two halves are not independent: the same conditions that make the tundra valuable make it fragile.
The case for fragility
- Slow recovery. Low temperatures and a brief growing season mean vehicle ruts and pipeline scars persist for decades; disturbed lichen mats supporting reindeer and caribou may take fifty years or more to regenerate.
- Simple food webs. Few species occupy each trophic level, so the loss of a single link — lemming, lichen, Arctic cod — cascades quickly.
- Permafrost carbon. Northern permafrost stores an estimated 1,400–1,600 gigatonnes of carbon, roughly twice the atmospheric stock; thaw releases carbon dioxide and methane in a self-reinforcing feedback.
- Amplified warming. The Arctic is warming close to four times the global mean, driving sea-ice loss, coastal erosion and species range shifts, with knock-on effects documented for the Indian monsoon.
- Pollutant accumulation. Persistent organic pollutants and mercury biomagnify in fat-rich Arctic food chains, concentrating in indigenous diets.
The case for economic importance
- The USGS estimates the Arctic holds about 13 per cent of undiscovered global oil and 30 per cent of undiscovered natural gas; Yamal LNG and Prudhoe Bay are already producing.
- Nickel, copper, palladium, rare earths, diamonds and phosphates at Norilsk, Kiruna and Greenland deposits.
- Barents and Bering Sea fisheries among the world's most productive.
- Retreating ice is opening the Northern Sea Route, cutting Rotterdam–Yokohama distances by around 40 per cent.
- Reindeer herding, tourism and, increasingly, scientific and strategic infrastructure.
Critical assessment
The relationship is not a simple trade-off. Extraction itself accelerates thaw, which in turn destroys the infrastructure built to extract — pipelines buckle, foundations fail, as at the Norilsk diesel spill of 2020. Governance is thin: the Arctic Council coordinates but does not regulate, and UNCLOS continental-shelf claims are contested. India's Arctic Policy (2022) and the Himadri station give it a research foothold, and the Himalayan cold desert makes Alpine tundra a direct domestic concern.
Conclusion
The tundra is economically important precisely because it has been undisturbed. Its fragility therefore is not a footnote to its value; it sets the terms on which that value can be realised at all.
What an examiner expects to see
- Tundra fragility stems from a growing season under three months, permafrost, simple food webs and decadal recovery times.
- Northern permafrost holds an estimated 1,400-1,600 Gt of carbon, roughly twice the atmospheric stock.
- Arctic amplification is warming the region close to four times the global average.
- Economic value: about 13% of undiscovered oil and 30% of undiscovered gas per USGS, plus nickel, rare earths and diamonds.
- Barents and Bering Sea fisheries and the opening Northern Sea Route add commercial weight.
- Extraction accelerates thaw, which destroys the very infrastructure built to extract - as the 2020 Norilsk spill showed.
- Governance is weak: the Arctic Council coordinates without regulating, and UNCLOS shelf claims are contested.
