Explain the impact of economic development on environmental degradation in India. (2016)
- Development acts on the environment through three separable effects — a scale effect (more output means more energy, material and land throughput), a composition effect (the mix shifts from agriculture to industry, then services), and a technique effect (richer economies buy cleaner processes). Degradation is their net.
- In India the scale effect has outrun the technique effect, so growth remains degradation-producing at the margin.
The Organising Frame: the Environmental Kuznets Curve
- Simon Kuznets proposed an inverted U between income inequality and income per head; Gene M. Grossman and Alan B. Krueger, studying the environmental consequences of a North American free-trade area in 1991, transposed the shape to pollution — damage rises with income, peaks, then falls.
- The turning point is not automatic. It appears where regulatory capacity, abatement technology and public demand arrive together — it is bought, not received.
- Estimated turning points for most pollutants lie at income levels several times India’s present per-head output, placing India firmly on the rising limb, with a policy choice about how high the peak is allowed to go.
The Sectoral Pathways from Growth to Damage
- Energy is the largest single channel. Coal still supplied about 73 per cent of electricity generation in 2025, and India’s carbon dioxide emissions reached about 3.19 billion tonnes in 2024, roughly 8.3 per cent of the world total.
- Industry concentrates damage rather than spreading it — a national inventory has long identified around twenty-four critically polluted industrial areas, Singrauli, Korba, Vapi, Ankleshwar and Angul-Talcher among them, where several polluting processes coincide in one airshed and catchment.
- Construction and materials — the building boom drives extraction of sand, aggregate, limestone and brick clay, degrading riverbeds and floodplains far from the city consuming them.
- Transport — rising vehicle numbers add emissions faster than fuel and engine standards subtract them.
- Irrigation — assured-water agriculture converted a surface-water system into a groundwater-mining one, the clearest case of a development success generating a resource deficit.
- Mining and infrastructure claim forest through diversion for projects, fragmenting habitat and catchment.
Where the Curve Bends and Where It Does Not
- It bends for pollutants that are local, visible and cheaply abated, and where an identifiable polluter can be regulated — leaded petrol withdrawn, gaseous fuel mandated for city fleets, particulate controls fitted at point sources.
- It does not bend for damage that is cumulative, diffuse or global — carbon, aquifer depletion, soil loss, total material throughput — because no local constituency suffers it visibly and no single agent can be fined for it.
- The current evidence shows exactly this split. In 2025 all incremental electricity demand was met from clean sources and coal generation fell about 2.9 per cent, with renewable capacity near 258 GW by December 2025 — relative decoupling and a genuine bend in the electricity pathway, while absolute emissions and material use continue to climb.
- Judgement: economic development in India has not been environmentally neutral, but neither is its damage fixed. The curve bends only where regulation, price and technology are applied deliberately — the electricity sector shows it can be done, and groundwater and carbon show what happens where it is not.
