UPSC Previous Year Question | Mains GS1 | 2020
How can the mountain ecosystem be restored from the negative impact of development initiatives and tourism? (Answer in 250 words)
Answer
Introduction
Mountain ecosystems are fragile because steep slopes, thin soils, high biodiversity and limited carrying capacity make disturbances difficult to reverse.

Introduction
Mountain ecosystems are fragile because steep slopes, thin soils, high biodiversity and limited carrying capacity make disturbances difficult to reverse.
Restoration measures
- Conduct cumulative environmental-impact and carrying-capacity assessments before roads, dams, tunnels and tourism projects.
- Use slope stabilisation, contour trenches, check dams, native afforestation and watershed treatment to reduce erosion and landslides.
- Protect springs, wetlands, glaciers and wildlife corridors through catchment-based planning and ecological flows.
- Promote decentralised renewable energy, resilient bridges, low-impact construction and climate-proof infrastructure.
- Adopt regulated homestays, visitor caps, waste segregation, sewage treatment, plastic control and responsible trekking.
- Empower gram sabhas, indigenous communities and local institutions in monitoring, benefit-sharing and disaster preparedness.
- Restore degraded habitats with native species rather than monoculture plantations, and maintain early-warning systems.
Trade-offs
Development cannot be stopped altogether; the objective is to shift from project-by-project clearance to landscape-level planning and ecological accounting.
Conclusion
Mountain restoration must combine science, local knowledge, livelihood security and strict enforcement of environmental safeguards.
