“Tundra regions are ecologically fragile but economically important.” Examine this statement critically.
GS110 Marks2026Model answer
Introduction
Tundra ecosystems — found in the high latitudes (Arctic, sub-Arctic) and high altitudes — combine low temperatures, short growing seasons, permafrost, and specialized biota. The statement links two truths: their ecological fragility and economic significance. A critical appraisal requires examining why they are fragile, what economic values they hold, the tensions between use and conservation, and pathways for sustainable management.
Quick synthesis (Value Addition Block — Key dynamics)
Why tundra are ecologically fragile
- Permafrost dependence — thawing alters hydrology and soils; slow vegetative recovery (years–decades) limits resilience. (Example: Siberian permafrost thaw releasing methane.)
- Low productivity and specialized species — limited redundancy: loss of one species can cascade. (Arctic fox, lichen-dependent caribou herds.)
- Short growing season and cryogenic soils — makes ecosystems vulnerable to disturbance (roads, drilling).
Why tundra are economically important
- Hydrocarbons & minerals — major oil/gas fields (e.g., Alaska, Yamal Peninsula) and mineral deposits drive national economies.
- Ecosystem services — carbon storage, climate regulation, freshwater provision and fisheries (Arctic fisheries).
- Cultural & tourism value — indigenous livelihoods, ecotourism, scientific research.
Tensions and critical issues
- Climate feedback loop: exploitation + warming → permafrost carbon release → amplifies global warming.
- Infrastructure damage & pollution: roads, pipelines fragment habitat and risk spills.
- Equity & indigenous rights: development often marginalizes local communities.
Way Forward / Balanced View
- Adopt precautionary, ecosystem-based management: strict EIA, limits on high-risk extraction.
- Strengthen indigenous co-management, benefit-sharing, and traditional knowledge integration.
- Invest in monitoring (satellite + field), low-impact technologies, and restoration pilots for disturbed soils.
- International cooperation via Arctic Council, align actions with SDG13/15 and climate commitments.
Conclusion
Tundra are both fragile and valuable; reconciling use with conservation needs the precautionary principle, strong governance, indigenous rights, and global climate action to preserve local ecosystems and global climate stability.
