UPSC Mains 2026 | General Studies Paper 1 | Geography | 10 Marks | 150 Words
Model Answer
Tundra regions, found mainly in the Arctic and above the alpine tree line, are characterised by extreme cold, short growing seasons and permafrost. Their ecological fragility contrasts with their growing economic significance.
Ecological Fragility
– Permafrost: Thawing causes ground subsidence and releases CO₂ and methane.
– Low resilience: Short growing seasons and slow vegetation growth make recovery from disturbances extremely slow.
– Climate sensitivity: Arctic warming and sea-ice loss threaten biodiversity and traditional livelihoods.
– Pollution vulnerability: Oil spills and mining-related contamination persist longer in cold environments.
Economic Importance
– Energy resources: Significant oil and natural-gas reserves occur in the Arctic.
– Minerals: Nickel, copper, iron ore and other strategic minerals support modern industries.
– Shipping: Retreating sea ice is increasing the significance of routes such as the Northern Sea Route.
– Livelihoods: Reindeer herding, fishing and tourism support indigenous and local economies.
However, resource extraction can itself accelerate permafrost degradation and ecosystem damage.
Conclusion: Therefore, tundra requires a precautionary, sustainable-development approach balancing resource utilisation with ecological conservation and indigenous rights.
1. Decode the Question: What is UPSC Asking?
The directive “Examine critically” requires a balanced assessment.
UPSC expects you to discuss:
Ecological Fragility
↓
Why tundra ecosystems are vulnerable
Economic Importance
↓
Why these regions attract economic activities
Critical Examination
↓
How economic exploitation can worsen ecological fragility
Way Forward
↓
Sustainable & regulated utilisation
Core Argument
«The same climate change that is making some Arctic resources more accessible is simultaneously increasing the ecological vulnerability of the tundra.»
2. How to Approach the Answer
For a 150-word answer:
Introduction
Define tundra + establish the paradox.
Body
Part A: Ecological fragility
Part B: Economic importance
Part C: Conflict between development and conservation
Conclusion
Suggest sustainable and precautionary governance.
Ideal structure:
Definition → Fragility → Economic Importance → Trade-off → Way Forward
3. Why Are Tundra Regions Ecologically Fragile?
1. Permafrost Dependence
Frozen ground supports the landscape and stores large quantities of carbon.
Thaw → Ground instability → Carbon release → Climate feedback
2.Slow Ecological Recovery
Very low temperatures and a short growing season mean vegetation regenerates slowly.
3.Biodiversity Vulnerability
Species such as polar bears, Arctic foxes, reindeer and migratory birds are highly dependent on specialised habitats.
4.Climate Sensitivity
Rapid Arctic warming can alter snow cover, sea ice, vegetation and food chains.
5. Pollution Persistence
Oil spills and industrial pollutants can remain in cold environments for long periods.
4. Why Are Tundra Regions Economically Important?
Oil & Natural Gas
The Arctic contains significant hydrocarbon resources, making it strategically important for energy security.
Example: Prudhoe Bay, Alaska and the Yamal region of Russia.
Minerals
The wider Arctic region contains important deposits of nickel, copper, iron ore, diamonds and other minerals.
Emerging Shipping Routes
Declining sea ice has increased interest in the Northern Sea Route, connecting the Atlantic and Pacific through Arctic waters.
Fisheries
Arctic and sub-Arctic waters support commercially important fisheries.
Indigenous Livelihoods
Reindeer herding, hunting and fishing remain economically and culturally significant for communities such as the Sami and Nenets.
5. The Critical Tension: Development vs Conservation
This is the most important analytical part of the answer.
Resource Extraction
↓
Roads + Pipelines + Mining + Drilling
↓
Habitat Disturbance
↓
Permafrost Degradation
↓
Carbon Release
↓
Further Climate Change
↓
Greater Ecological Vulnerability
Thus, economic exploitation can undermine the very ecosystem on which long-term regional sustainability depends.

7. Value Addition for UPSC
Key Terms
Use 3–4 of these in your answer:
– Permafrost
– Arctic Amplification
– Thermokarst
– Carbon Feedback
– Northern Sea Route
– Critical Minerals
– Indigenous Livelihoods
– Environmental Justice
Examples
Prudhoe Bay → Arctic hydrocarbons
Yamal → Natural gas/LNG
Northern Sea Route → Emerging Arctic shipping corridor
Norilsk → Mining and environmental concerns
Sami/Nenets → Indigenous livelihoods
8. Previous UPSC PYQ Connection
This question has a strong connection with earlier UPSC questions on the Arctic region.
UPSC 2015
Asked about the economic significance of oil discovery in the Arctic Sea and its environmental consequences.
UPSC 2018
Asked why India is taking keen interest in the resources of the Arctic region.
UPSC 2021
Asked about the impact of melting Arctic and Antarctic ice on weather patterns and human activities.
Thus, UPSC 2026 combines these dimensions into one question:
Resources + Environment + Climate Change + Human Activities.
9. India Angle
India’s interest in the Arctic is linked to:
· Scientific research
· Climate studies
· Changing sea routes
· Monsoon variability
· Himalayan–Arctic linkages
· International cooperation
India’s Arctic Policy 2022 focuses on scientific research, climate and environmental protection, economic and human development, transportation and connectivity, governance and international cooperation, and national capacity building.
UPSC Tip: Mentioning India’s Arctic engagement can add a strong contemporary dimension to the conclusion.

11. Mains Takeaway
Don’t write a one-sided answer.
The examiner wants the paradox:
«Tundra is environmentally fragile, yet its resources and strategic location make it economically valuable.»
The highest-value analytical link is:
Economic Exploitation → Environmental Degradation → Permafrost Thaw → Climate Feedback
One-Line Revision
Tundra = Fragile Ecosystem + Resource-Rich Frontier + Climate-Sensitive Region → Need for Sustainable Governance.
