GS Paper I 2023

Ancient India grew inside a clear physical frame: mountains and seas enclosed it, while passes, rivers and coasts kept its regions connected. Each feature shaped settlement, production and power.

Mountains: shield and gateway

• Himalayan wall: blocked easy entry from the north and traps the monsoon winds, making them shed their moisture within the subcontinent.
• North-western passes: the Khyber and the Bolan admitted migrants, traders and armies, and with them new crafts and ideas.

Both Gandhi and Tagore rejected colonial schooling, which Gandhi said made Indians "strangers in their own lands", but they differed on what education and the nation were for.

Approach towards education

• Gandhi, education for self-respect: colonial education enslaved minds, so he wanted Indian languages as the medium and learning that restored dignity.
• Craft at the core: under Nai Talim, literacy alone was not education; pupils had to work with their hands and learn a craft.
• Tagore, education for creativity: schools killed a child's wonder, so he built Santiniketan, an abode of peace in rural Bengal.
• Blending traditions: science and technology sat beside art and music; Visva-Bharati's Kala Bhavana (1919) was India's first nationalist art school.

The first public railway opened between Stockton and Darlington in England in 1825. Railways soon remade economies and societies from Europe to colonial Asia, with effects shaped by who built them, and for whom.

Economic effects

✏️ Table to draw in your answer

• Industrial linkage: cheap, fast freight joined regional markets and fed demand for coal, iron and engineering.
• Opening continents: the railroad drove westward expansion of industry and trade in America; Canada's transcontinental lines still carry most of its wheat and coal.
• Colonial pattern: the Bombay–Thane line (1853) began a network tying hinterlands to ports, serving imperial trade over local industry.
• Ecological cost: forests fell for sleepers; in Garhwal and Kumaon, oak gave way to chir pine needed for railway lines.

The IPCC's Sixth Assessment Report (WGII) finds, with high confidence, that climate change will increasingly pressure food production and access in vulnerable regions. Agrarian, rain-fed tropical countries, already farming near crops' heat limits, feel this first, across all four pillars of food security.

✏️ Flowchart to draw in your answer

Availability: less food grown

• Yield loss: without adaptation, Indian projections show rainfed rice yields falling 20% by 2050 and 47% by 2080, and wheat 19.3% by 2050 (PIB, 2024).
• Pests and water: warmer, wetter spells spread pests, while coastal salinity and erratic river flows weaken irrigation.
• Livestock and fisheries: heat stress lowers milk output; warming seas and coral loss shrink the fish catch of the coastal poor.

In 2022, roughly half the world's population faced severe water scarcity for part of the year, and 2.2 billion lacked safely managed drinking water (UN). The crisis is one of quantity and of reach.

Why availability is shrinking

• Finite, uneven supply: usable freshwater is a small share of all water, unevenly spread across regions and seasons.
• Farm-heavy demand: agriculture takes 72% of freshwater withdrawals (UN WWDR 2024), while cities and industry add more.
• Over-extraction and pollution: aquifers are pumped faster than they recharge; sewage, effluents and agrochemicals spoil the rest.
• Climate change: shifting rainfall, glacier melt and saline intrusion disturb supply; droughts hit 1.4 billion people in 2002–2021.

NCERT describes fjords as very deep glacial troughs filled with sea water along high-latitude shorelines, with famous examples in Norway, Chile and New Zealand. Ice made them, and ice also made them beautiful.

How fjords are formed

✏️ Flowchart to draw in your answer

• Glacial erosion: moving ice plucks and abrades rock, turning V-shaped river valleys into steep U-shaped troughs.
• Over-deepening: thick ice cuts deepest inland; near the mouth it thins, leaving a shallow rock sill behind which the water stays deep.
• Drowning: post-glacial sea-level rise floods the trough, giving an indented coast where hillsides drop sharply into the water.
• Hanging valleys: smaller tributary glaciers cut shallower troughs that now hang above the fjord.

In the middle Ganga plain the rain-bearing monsoon blows from the east, so Bhojpuri speech calls it Purvaiya, the easterly. The name is geography; its songs are culture.

Why the south-west monsoon is 'Purvaiya'

• Deflection: the Arakan Hills turn the Bay of Bengal branch into West Bengal from the south and south-east.
• Channelling: the Himalaya and the north-west thermal low send one arm westward along the Ganga plain.
• Local contrast: the local westerly is the dry summer loo, so only the easterly means rain.

In Hindu tradition marriage is a samskara, a sacred lifelong union of duty rather than a contract. Modern India has not discarded this ideal; it is rewriting its terms.

Signs the sacrament is weakening

• Law of exit: Section 13-B of the Hindu Marriage Act allows divorce by mutual consent, making an indissoluble bond dissoluble.
• Judicial shift: in Shilpa Sailesh (2023) a Constitution Bench held the Supreme Court may dissolve a marriage under Article 142(1) for irretrievable breakdown, even if one spouse opposes.
• Choice over duty: education, women's paid work and city life make compatibility the test; live-in, inter-caste and inter-faith unions are more visible.

NCRB's suicide rate rose from 12.0 to 12.4 per lakh in 2021–22 (since then, 171,418 suicides were counted for 2023, 27.2% of them women). As Durkheim argued, such rates have social causes; for young women these lie in family and gender norms.

✏️ Diagram to draw in your answer

Why suicides are rising

• Marriage pressure: 23% of women aged 20–24 were married before 18 (NFHS-5); dowry and isolation in a new home breed despair.
• Violence at home: domestic cruelty, weak shelters and slow courts leave few exits.
• Curbs on autonomy: honour-based control over partner, dress, mobility and career collides with rising aspirations.
• Aspiration gap: more young women finish college, but scarce jobs and exam pressure breed frustration.
• Digital harm: cyber-harassment, morphed images and body-image comparison add shame.
• Mental-health gap: stigma, few counsellors and family denial leave depression untreated; pesticides make impulses fatal.

The family is the site of primary socialisation, whose most critical stage comes in the early years (NCERT). A phone in place of the lap robs that first school of its teacher.

✏️ Diagram to draw in your answer

Impact on socialisation

• Attachment: cuddling and eye contact build trust; a screen cannot respond, so security weakens.
• Language and thought: words grow in back-and-forth talk; passive viewing slows vocabulary, attention and imagination.
• Social skills: shared meals and play teach turn-taking, empathy and patience; screens teach none of these.
• Self-control: the phone as pacifier stops a child learning to wait or calm down; tantrums follow its removal.
• Values: advertising and unfiltered content become silent teachers, sidelining parents.
• Health: poor sleep, eye strain, less outdoor play.

The Rigveda, compiled c. 1500–1000 BCE in the Sapta-Sindhu region, records a pastoral, kin-based people; later Vedic texts show settled kingdoms, sharper hierarchy and elaborate ritual. Several of these features still shape Indian society, though in altered form.

Main features of Vedic society

• Kinship base: the family (kula) was inseparable from the jana; later, kula came to mean a household of several kin members.
• Women: they attended the sabha and joined rituals; Rigvedic hymns are attributed to women sages such as Apala, Ghosha and Lopamudra.
• Life stages: the ashrama scheme divided life into brahmacharya, grihastha, vanaprastha and sanyasa, guided by dharma, artha, kama and moksha.

The Delhi Sultanate, established in 1206, tied northern India to West and Central Asia. Along that link came techniques that changed how Indians irrigated, spun, wrote, built and fought, and through them, how society was organised.

Major technological changes

• Water-lifting: the Persian wheel, a geared chain of pots, lifted water from deep wells; the Babur Nama later described such devices across north India.
• Textiles: the spinning wheel (charkha) and cotton-carding bow multiplied yarn output; the Sufi Charkhanama, a song set to its rhythm, shows how familiar it became.
• Paper: it spread for records, accounts and books, gradually displacing palm leaf and birch bark.
• Building: the true arch, dome and lime mortar, and waterworks such as the Hauz Khas tank, built by Alauddin Khalji to supply Siri Fort.
• Warfare: improved cavalry equipment, and late in the period gunpowder: Babur's victory over Ibrahim Lodi at Panipat (1526) relied heavily on field artillery.

Tribal communities lived by shifting cultivation, forest produce and customary rights over land. Colonial revenue and forest laws turned them into indebted tenants and wage labourers, and they replied with some of India's earliest anti-colonial revolts.

How colonial rule affected tribals

• Land and debt: cash revenue and private property opened tribal land to moneylenders, traders and landlords, the dikus; unpaid debts meant lost land.
• Forests: the Indian Forest Act, 1878 reserved forests for timber and railways, curbing grazing, jhum and minor produce, so customary use became crime.
• Labour: tribals were recruited for tea plantations, mines and railway works, often under coercive contracts far from home.
• Stigma and intrusion: the Criminal Tribes Act, 1871 labelled communities criminal by birth; police, courts and missions eroded village autonomy.

India's coastline of about 7,516 km, with the Andaman and Nicobar and Lakshadweep islands, holds fish, minerals, energy and trade routes. Yet about 5,700 km of it is extremely vulnerable to cyclones, storm surges and heavy rain, so wealth and risk must be managed together.

Resource potential of the long coastline

• Living resources: marine fisheries, aquaculture and seaweed sustain fishing communities; mangroves and reefs act as fish nurseries and carbon sinks.
• Strategic minerals: the world's richest monazite deposits lie in Kerala's Palakkad and Kollam districts, a source of thorium for nuclear power.
• Ports and trade: 12 major and about 200 minor ports carry most foreign trade; Sagarmala pushes port-led industry, shipbuilding and coastal shipping.
• Blue frontier: the Deep Ocean Mission (Rs 4,077 crore over five years) explores the deep sea; offshore wind, tidal energy and coastal tourism add potential.

India has temperate vegetation on Himalayan heights, tropical rain forests in the Western Ghats and the Andaman and Nicobar Islands, thorn forests in the dry north-west and mangroves in deltas. This diversity flows from climate, relief, soil and history, and its rain-forest core needs protection.

Factors behind diversity of natural vegetation

• Rainfall: the decisive control; over 200 cm with mean temperature above 22°C gives tropical evergreen forest, while under 50 cm gives thorn forest.
• Seasonality: the monsoon's long dry spell makes most Indian forests deciduous, shedding leaves to save water.
• Altitude: the Himalaya stacks tropical, temperate and alpine belts; deodar, a valued endemic, grows mainly in the western Himalaya.
• Relief and aspect: windward slopes are wetter than leeward ones, and north- and south-facing slopes receive different sunlight.
• Soil and drainage: laterite, black, alluvial and desert soils carry different plant communities; waterlogged deltas grow mangroves.
• Isolation and people: island arcs develop distinct vegetation, while clearing, grazing and fire leave secondary growth.

Human development, a concept introduced by Mahbub-ul-Haq and tied by Amartya Sen to building capabilities, measures people's choices, not output. India grew fast, yet it ranked 132nd in the Human Development Report 2021-22 and, since then, only 130th in the HDR 2025, with just 6.9 mean years of schooling. The reasons lie in how growth was made and shared.

Why growth did not become human development

• Jobless pattern: output rose in capital- and skill-intensive services, while farm and informal work, where most Indians earn, stayed low-paid; economists call this jobless growth.
• Thin public spending: the Economic Survey 2020-21 urged lifting public health spending from 1% to 2.5–3% of GDP, which would cut out-of-pocket spending from 65% to 35%.
• Unequal gains: benefits concentrated by class, caste, gender and region, so Bihar and Uttar Pradesh still trail Kerala and Tamil Nadu on most social indicators.
• Weak delivery: absent teachers and doctors, leakages and under-funded local bodies meant schemes built classrooms and clinics faster than learning or health.
• Nutrition trap: NFHS-5 (2019–21) found 35.5% of under-five children stunted, which blunts learning in school and earnings later.
• Gender norms: patriarchy keeps women's paid work and girls' higher schooling low, wasting half the country's human capital.

• HYV seeds: high-yielding wheat from Mexico and rice from the Philippines were available by the mid-1960s, and India adopted them quickly.
• Package approach: seeds came with fertiliser, pesticides and assured irrigation from tube-wells and canals, first in Punjab, Haryana and western Uttar Pradesh.

Parliament was told in March 2025 that about 6.54 crore Indians live in slums, in 1.39 crore households, a count based on Census 2011. Indian metropolises do segregate and marginalise the poor, but this flows from how land, housing and services are governed rather than from urban growth itself.

✏️ Flowchart to draw in your answer

Yes: segregation in space

• Priced out: high land values push the poor into slums, pavements and peripheral resettlement colonies, far from jobs; Mumbai's Dharavi is the best-known face of this.
• Secession of the rich: gated enclaves, private schools and private hospitals let the affluent opt out of shared public services.
• Identity enclaves: landlords and housing societies screen tenants by caste and religion, so Dalit and Muslim families often cluster in separate pockets.

M.N. Srinivas, through his ideas of Sanskritisation and dominant caste, showed that caste was never a frozen ladder. Yet birth still fixes membership. Caste is fluid in what it does and static in who belongs.

✏️ Table to draw in your answer

Why caste identity is static

• Ascription: membership comes by birth and cannot be resigned or earned.
• Endogamy: marriage within the caste reproduces it every generation and blocks the blurring of caste lines.
• Hierarchy: Article 17 abolished untouchability, and the SC/ST (Prevention of Atrocities) Act, 1989 strengthened punishment, yet exclusion from homes, water and temples persists in places.
• Descent-based work: manual scavenging, still done mostly by Dalits, shows how stigma clings to birth.

The New Economic Policy of 1991 raised growth and aspirations but spread them unevenly across regions and groups. In a plural society, identity became a means to claim or defend economic space, so liberalisation has both sharpened and softened ethnic and communal lines.

✏️ Diagram to draw in your answer

Impact on ethnic identity

• Relative deprivation: regional gaps and jobless growth feed statehood demands framed as identity; Telangana was carved out of Andhra Pradesh in 2014.
• Nativism: migrants moving to richer states and cities compete for jobs and housing, sparking sons-of-the-soil hostility to outsiders.
• Displacement: demand for land and minerals meets Adivasi resistance, as when the Dongria Kondh defended the sacred Niyamgiri hills in Odisha.
• Cultural assertion: global markets spread cosmopolitan tastes and, in reaction, a defensive pride in language, dress and tradition.
