Model answer
Drafted with AI by UPSC Answer Check against this question's marking rubric, to the 250-word length. UPSC does not publish answers for Mains — this is one way to score well, not an official key. How we build rubrics and answers.
Human-induced land-use and land-cover change (LULCC) in India reflects competing demands on land. Underlying drivers include population growth, rising incomes and market integration, and policy incentives such as assured procurement and free farm power that favour paddy and wheat.
Agricultural Intensification and Expansion The paddy-wheat cycle in Punjab has depleted groundwater and degraded soils. Expansion of commercial farming and horticulture into forest fringes fragments habitats and creates edge effects, while shortened jhum (shifting cultivation) cycles in the North-East degrade hill forests and increase erosion.
Urbanisation and Sprawl Unplanned growth has converted wetlands and encroached on floodplains. The loss of Bengaluru's interconnected lakes and the reclamation of parts of the East Kolkata Wetlands (a Ramsar site) for Salt Lake and later real estate have impaired drainage, reduced recharge and worsened urban flooding, while concrete replacing vegetation intensifies Urban Heat Islands.
Mining and Infrastructure Forest diversion for open-cast coal mining in Jharkhand and Chhattisgarh has accelerated erosion, scarred landscapes and destroyed habitats. Highways and large dams in fragile terrain trigger slope instability and sever wildlife corridors.
Coastal Change Aquaculture and coastal development have cleared mangroves in the Godavari-Krishna delta and parts of the Sundarbans, increasing coastal erosion and exposure to cyclones, storm surges and saline ingress into aquifers.
An integrated national land-use policy, agro-ecological zoning, carrying-capacity limits and landscape-level restoration can reconcile development with ecological resilience.
How this answer will be evaluated
Framework: GS1 Geography: Human-Environment Interaction
What earns full marks: Analyzes drivers with specific mechanisms and links them to distinct geographical consequences.
Evaluation rubric
Each sub-part is marked on its own, against the marks and word limit printed on the paper.
- The answer Analyse the major human drivers of land-use change in India (agriculture, urbanisation, mining, infrastructure, coastal development, and their underlying socio-economic and policy causes) and their geographical consequences. 15 marks · 250 words
analyse— intro → causes → effects → stakeholders/linkages → way forward
Must cover
- Identify drivers: urbanization, industrialization, agriculture, infrastructure.
- Explain the mechanism of change (e.g., conversion of forest to urban).
- Detail geographical consequences: hydrological, ecological, or climatic.
- Link specific drivers to specific regional consequences.
Loses marks
- Listing drivers without explaining the mechanism of change.
- Narrating chronology of land use without causal analysis.
- Ignoring the 'geographical' aspect of the consequences.
Earns more
- Specific policies or schemes (e.g., Green Revolution incentives, Smart Cities)
- Specific regions (e.g., Punjab plains, Bengaluru, Jharkhand–Chhattisgarh, Godavari–Krishna delta)
- Impact on biodiversity, water table or flood risk
- Underlying drivers: population, incomes, market integration, policy incentives
Extra mark
- 30-second sketch map showing a specific land-use shift.
- One robust statistic on forest cover or urban expansion.
What "Analyse" is asking you to do
Break the subject into its working parts and show how they act on each other. The marks are in the interconnections — which factor drives which, and what the resulting structure explains — not in the inventory of factors.
Structure that answers it
Define the whole → separate it into its parts → show which part drives which → what that interaction produces → what the structure implies
Where marks are lost
A flat list of causes with no account of which drives which. An answer of neatly separated headings, each self-contained, scores as description.
