Analyze the major drivers of human-induced land-use changes in India and their geographical consequences.
Land-use in India has undergone profound transformation since independence, driven overwhelmingly by anthropogenic factors, with far-reaching geographical, ecological and socio-economic consequences.
Major Drivers:
- Population growth and urbanisation:
- Urban population rose from 17% (1951) to over 35% (2023).
- Peri-urban sprawl converts prime agricultural land (NCR, Bengaluru, Hyderabad).
- Agricultural intensification and expansion:
- Green Revolution expanded irrigated cropland in Punjab, Haryana, western UP.
- Encroachment on forests and wetlands, especially in Northeast and Western Ghats.
- Industrialisation and infrastructure:
- SEZs, industrial corridors (DMIC), highways, dedicated freight corridors.
- Mining in Jharkhand, Odisha, Chhattisgarh converting forest land.
- Energy projects:
- Large hydro (Tehri, Sardar Sarovar), thermal plants, solar parks (Bhadla, Pavagada) alter vast tracts.
- Commercial plantations:
- Tea, rubber, oil palm (rising under National Mission on Edible Oils) replacing natural forests.
- Policy and market forces:
- Land acquisition laws, MSP-driven cropping (paddy in Punjab), real estate speculation.
- Climate-induced shifts:
- Shifting agriculture, coastal erosion forcing relocation.
Geographical Consequences:
- Deforestation and biodiversity loss: India lost 2.3 million ha of tree cover (2001–2022, GFW).
- Soil degradation: Around 30% of land is degraded (ISRO Atlas); salinisation in canal-irrigated areas.
- Groundwater depletion: Punjab, Haryana, western UP show alarming decline (CGWB).
- Urban heat islands and air pollution: Delhi, Mumbai, Kolkata face rising temperatures.
- Wetland loss: East Kolkata, Pallikaranai, Deepor Beel under threat.
- Fragmentation of wildlife corridors: Human-elephant, human-leopard conflict rising.
- Coastal squeeze: Mangrove loss in Sundarbans, Gujarat.
- Displacement: Tribal communities affected by mining and dam projects (Narmada, Polavaram).
Way Forward:
Integrated land-use planning, enforcement of Forest Rights Act, restoration under Bonn Challenge (26 million ha commitment), agroforestry, compact urbanisation and satellite-based monitoring are essential to reconcile development with ecological sustainability.
