Environment and Society
It explains how nature and society continuously shape each other through social organisation, values and knowledge, and the environmental problems and risks this interaction produces.
This is the conceptual backbone for the environment-development debate that UPSC tests heavily. Prelims mines its static nuggets (Prosopis juliflora, Bhopal/MIC, greenhouse gases, groundwater-stressed states, WHO air-pollution data), while Mains uses it for GS-III (pollution, resource depletion, climate change, disaster management) and GS-I (Indian society, gender, urbanisation).
Understand the chapter
The Ecological Basis of All Societies
Every object we use ultimately draws on natural resources, so all societies rest on an ecological foundation. Ecology is the web of physical and biological systems and processes of which humans are just one element, and a place's ecology is shaped by the interaction of its geography and hydrology. These factors set limits on how humans can live anywhere — a desert's scarce rainfall and extreme temperatures dictate sparse, mobile lifestyles.
- Ecology = web of physical and biological systems and processes; humans are one element within it.
- A place's ecology is shaped by the interaction of its geography and hydrology.
- Ecological factors (rainfall, soil, temperature) limit and shape human settlement and culture.
A Two-Way Street: Nature Shapes Society, Society Shapes Nature
Social environments emerge from the interaction of biophysical ecology and human intervention, and this works both ways. Nature shapes society — the fertile Indo-Gangetic floodplain enables intensive agriculture, dense populations, surpluses and complex hierarchical states, while the Rajasthan desert supports only mobile pastoralists. Society also reshapes nature: capitalist commodities like the private automobile transform landscapes through pollution, congestion, oil conflicts and warming. Crucially, much that looks 'natural' is actually human-made.
- Nature → society: Indo-Gangetic fertility breeds intensive farming, dense settlement and states; Rajasthan desert breeds nomadic pastoralism.
- Society → nature: capitalist commodities (e.g., the car) cause air pollution, congestion, oil wars and global warming.
- Deceptively 'natural': Delhi's Ridge forest was planted by the British (~1915) with exotic Prosopis juliflora.
- Corbett's chaurs (grassy meadows) were once farm fields; villages were relocated to create a 'pristine' wilderness.
Social Organisation: Property, Labour and Gender
How a society uses nature is governed by its social organisation, especially property relations and the division of labour. Who owns forests, land or water decides who may use them and on what terms — government forests can be leased to timber firms or opened to villagers. Because tasks are divided by class and gender, landless labourers and women relate to resources differently from propertied men. In rural India women feel scarcity most acutely, since fetching water and gathering fuel are women's work, yet they do not control these resources.
- Property relations decide who can use a resource and on what terms.
- Division of labour ties resource control to class and gender.
- Rural women bear scarcity hardest — they gather fuel and fetch water but do not own or control them.
Values, Knowledge and Perspectives
Different society-environment relationships reflect different values, norms and knowledge systems. Capitalist values commodify nature, stripping a river's ecological, utilitarian, spiritual and aesthetic meanings down to profit and loss; socialist values of equality have driven land seizure and redistribution to landless peasants; religious values both protect sacred groves and elsewhere sanction exploiting nature. Debates like nature-versus-nurture show how ideas — such as that women or Blacks were 'naturally' inferior — are products of their social conditions, challenged as equality spread during the 18th century's revolutions, while colonialism built whole disciplines to extract resources for empire.
- Capitalism commodifies nature (a river reduced from many meanings to profit and loss).
- Socialism redistributes land; religion guards sacred groves (or grants divine sanction to exploit).
- Nature-nurture debate: is disadvantage innate or born of circumstance?
- Colonial sciences — geology, geography, botany, zoology, forestry, hydraulic engineering — were institutionalised for resource extraction.
Risk Society and Industrial Disasters
Modern industrialisation has accelerated resource extraction and created complex, fragile technologies we do not fully understand, making us a 'risk society'. Disasters like Chernobyl (nuclear), Bhopal (industrial) and Mad Cow disease in Europe reveal the dangers built into industrial environments. The 1984 Bhopal gas tragedy — a methyl isocyanate leak from a Union Carbide pesticide plant — killed about 4,000 and disabled some 200,000, and exposed how corporate negligence and political-bureaucratic collusion ignored repeated warnings.
- Risk society: we depend on technologies and products we do not fully grasp.
- Examples: Chernobyl (nuclear), Bhopal (industrial chemical), Mad Cow disease (Europe).
- Bhopal: 3 December 1984, MIC gas, Union Carbide; plant under-designed and lacked a computerised early-warning system.
- CSE's State of India's Environment (Second Citizens' Report) spread blame across company, state and central government.
Major Environmental Problems and Risks
The chapter sorts the main globally recognised problems into three heads. Resource depletion empties non-renewables — groundwater aquifers (acute in Punjab, Haryana, UP), topsoil lost to erosion, salinisation and brick-making, and biodiversity habitats shrinking as agriculture expands. Pollution of air, water and noise harms health, with WHO linking around 7 million deaths in 2012 to air pollution. Global warming from greenhouse gases like carbon dioxide and methane raises temperatures, melts polar ice and threatens coasts.
- Resource depletion: groundwater (Punjab, Haryana, UP), topsoil (erosion, water-logging, salinisation), biodiversity loss (e.g., falling tiger numbers).
- Air pollution — WHO 2012: ~7 million deaths (1 in 8 globally); indoor 3.3M (chulha smoke, rural women) vs outdoor 2.6M.
- Water pollution from sewage, factory effluents and farm runoff of fertilisers/pesticides; noise pollution from loudspeakers, traffic and construction.
- Global warming: CO2 and methane trap heat → ice-melt, sea-level rise, climatic uncertainty.

Must-know facts exam-ready
- Ecology = web of physical and biological systems and processes of which humans are one element.
- Delhi's Ridge forest was planted by the British around 1915; its dominant tree Prosopis juliflora (vilayati kikar) is exotic, brought from South America.
- The chaurs (grassy meadows) of Corbett National Park, Uttarakhand were once agricultural fields; villages were relocated.
- Bhopal gas tragedy: night of 3 December 1984; the gas was methyl isocyanate (MIC) from a Union Carbide pesticide factory.
- Bhopal killed about 4,000 people and left about 200,000 permanently disabled.
- Union Carbide came to Bhopal in 1977 amid rising pesticide demand after the Green Revolution.
- The Bhopal analysis appeared in CSE's State of India's Environment: The Second Citizens' Report.
- Groundwater depletion is most acute in Punjab, Haryana and Uttar Pradesh.
- WHO: in 2012 around 7 million people died (1 in 8 of global deaths) from air pollution — the largest single environmental health risk; 3.3 million indoor and 2.6 million outdoor.
- Named greenhouse gases: carbon dioxide and methane.
- Risk-society examples: Chernobyl (nuclear), Bhopal (industrial), Mad Cow disease (Europe).
- Indo-Gangetic floodplain supports intensive agriculture and complex states; Rajasthan desert supports only mobile pastoralism.
Memory tricks remember it for good
Traps to avoid
- Delhi's Ridge forest is NOT natural vegetation — it was planted by the British (~1915), and Prosopis juliflora is exotic from South America, not native.
- Corbett's chaurs are not 'pristine wilderness' — they were farmland, and villages were relocated to make the area look wild.
- Bhopal's gas was methyl isocyanate (MIC) from a Union Carbide pesticide plant in 1984 — don't confuse it with Chernobyl (nuclear), a separate risk-society example.
- Aridity and flood-proneness are often human-produced (deforestation in a river's upper catchment makes it flood-prone), not purely natural.
- In WHO's 2012 data, indoor air-pollution deaths (3.3 million) exceeded outdoor (2.6 million) — don't assume urban/outdoor pollution is the bigger killer; rural women at chulhas are highly exposed.
- Global warming is about the greenhouse effect (CO2, methane trapping heat) — don't conflate it with ozone-layer depletion.
Exam focus
🧠 Prelims angles
- Exotic species Prosopis juliflora (vilayati kikar/babul), introduced from South America and naturalised across north India.
- Bhopal disaster static facts: methyl isocyanate (MIC), Union Carbide, 3 December 1984.
- Greenhouse gases and the greenhouse effect: carbon dioxide and methane; impacts on polar ice and sea level.
- Groundwater-stressed states (Punjab, Haryana, Uttar Pradesh) and soil degradation terms (erosion, water-logging, salinisation).
- WHO air-pollution mortality figures and the indoor vs outdoor split (2012).
- Protected areas in focus: Corbett National Park (Uttarakhand); tiger population decline despite sanctuaries and strict laws.
✍️ Mains angles GS-III
- 'Society shapes nature as much as nature shapes society.' Examine with examples.Use the two-way framework — Indo-Gangetic farming vs Rajasthan pastoralism (nature→society) and capitalism, the automobile and commodification (society→nature).
- Rural women bear the heaviest burden of environmental scarcity. Discuss.Link the gendered division of labour (fuel and water gathering) with lack of resource control; bring in indoor air pollution and an ecofeminism angle.
- Industrial disasters like Bhopal are failures of institutions, not mere accidents. Comment.Spread accountability across corporate negligence, the state pollution board, central clearances and political-bureaucratic collusion; suggest siting, safety-audit and EIA reforms.
- Colonial knowledge systems were instruments of resource extraction. Analyse.Connect institutionalised disciplines (forestry, geology, botany) to the knowledge-power nexus serving imperial control.
