Analyze the importance of Ashokan inscriptions for reconstructing Mauryan history.

Value Addition

Ashokan inscriptions are the most reliable contemporary primary sources for Mauryan history. They reveal imperial geography, administration, Dhamma and Ashoka’s conception of kingshi

KEYWORDS Epigraphy • Primary source • Dhamma-vijaya • Paternal kingship • Imperial integration • Dhamma-Mahamatras

• Rock Edict XIII records the Kalinga War, remorse and the shift from conquest by war to conquest through Dhamma.

• References to Rajukas, Yuktas, Pradesikas and Dhamma-Mahamatras help reconstruct Mauryan administration.

• Prakrit-Brahmi, Kharoshthi, Greek and Aramaic inscriptions reveal linguistic and regional adaptation across the empire.

• References to Cholas, Pandyas, Keralaputras and Hellenistic rulers illuminate external contacts.

DATA / FACT: Ashoka’s corpus includes 14 Major Rock Edicts and 7 Major Pillar Edicts, besides minor and separate edicts.

CASE STUDY / EXAMPLE: Maski inscription is crucial because it explicitly uses the name “Ashoka”, helping identify Devanampiya Piyadasi with Ashoka; Dhauli and Jaugada show special post-Kalinga instructions.

QUOTE / USE AS LINE: Ashoka: “All men are my children.”

FUTURE-ORIENTED CONCLUSION: India’s heritage vision should combine ASI conservation, epigraphy, archaeology, scientific dating and digital documentation so ancient history becomes increasingly evidence-based and publicly accessible.

Discuss the impact of Macaulay’s Minute on colonial administration and education in India.

Value Addition

Macaulay’s Minute of 1835 privileged English and Western learning, producing an English-educated intermediary class useful to colonial administration while unintentionally nurturing modern Indian nationalism.

KEYWORDS Anglicist–Orientalist debate • Downward filtration • Colonial modernity • Administrative utility • Cultural hegemony • New middle class

• English became central to higher education and administration, while traditional Sanskrit/Persian institutions lost official priority.

• It supplied clerks, teachers, lawyers and subordinate officials at relatively low cost to the colonial state.

• Western liberal ideas – liberty, equality, constitutionalism and nationalism – entered the intellectual world of the new middle class.

• The same educated elite later became a major force behind reform associations, newspapers and nationalist politics.

DATA / FACT: 2 February 1835: Macaulay submitted his Minute; the policy turn was accepted under Governor-General William Bentinck.

CASE STUDY / EXAMPLE: Universities of Calcutta, Bombay and Madras were established in 1857, consolidating the English-oriented higher-education framework.

QUOTE / USE AS LINE: Macaulay sought a class “Indian in blood and colour, but English in tastes...”

FUTURE-ORIENTED CONCLUSION: NEP 2020 seeks to correct the colonial imbalance through multilingualism, mother-tongue learning and Indian Knowledge Systems while retaining access to global knowledge – a move from colonial utility to intellectual self-confidence.

Official / authoritative source: NCERT; Ministry of Education – National Education Policy 2020.

“The significance of the Gandhian movements lay in the masses they mobilized.” Elucidate.

Value Addition

Gandhi transformed Indian nationalism from elite petitioning into participatory mass politics by linking national freedom with the everyday grievances of peasants, workers, women, students and local communities.

KEYWORDS Mass nationalism • Satyagraha • Ahimsa • Political socialisation • Subaltern participation • Constructive programme • Moral legitimacy

• Champaran mobilised indigo peasants; Ahmedabad mill workers; Kheda cultivators – connecting nationalism with local suffering.

• Non-Cooperation widened participation to students, traders, peasants and religious groups.

• Civil Disobedience drew women, peasants and business groups into open defiance through salt, boycott and no-tax campaigns.

• Quit India witnessed youth, students, underground networks and parallel governments, showing deep diffusion of nationalism.

DATA / FACT: Gandhi began the Dandi March in 1930 with 78 selected volunteers; the Salt Satyagraha rapidly became a nationwide symbol of resistance.

CASE STUDY / EXAMPLE: Parallel governments at Tamluk, Ballia and Satara (Prati Sarkar) during Quit India show the grassroots depth of mobilisation.

QUOTE / USE AS LINE: Gandhi: “Non-cooperation with evil is as much a duty as cooperation with good.”

FUTURE-ORIENTED CONCLUSION: Gandhi’s legacy survives in the democratic principle of Jan Bhagidari: citizens must be participants, not passive beneficiaries. A Viksit Bharat requires the same mass ownership of public goals.

What is the Fujiwhara effect? Explain its impact on the movement and intensity of tropical cyclones.

Value Addition

The Fujiwhara Effect occurs when two nearby cyclonic vortices interact and begin rotating around a common centre, producing complex changes in track, structure and sometimes intensity.

KEYWORDS Binary cyclone interaction • Common centroid • Vortex interaction • Track deflection • Capture • Merger • Forecast uncertainty

• Cyclones of comparable strength may orbit each other around a shared centroid.

• A stronger cyclone can capture or absorb the weaker vortex.

• Mutual interaction may abruptly alter the predicted track and increase landfall uncertainty.

• Fujiwhara interaction does not automatically intensify cyclones; it may strengthen, weaken, distort or merge the systems.

DATA / FACT: IMD literature documents binary-vortex interactions and track modification in tropical cyclones over the Indian seas.

CASE STUDY / EXAMPLE: Two cyclones over the Indian seas in November 1977 showed marked double-vortex motion and track changes associated with mutual interaction.

QUOTE / USE AS LINE: Use as line: “Fujiwhara interaction is primarily a problem of nonlinear motion and forecast uncertainty, not guaranteed intensification.”

FUTURE-ORIENTED CONCLUSION: Mission Mausam, Doppler weather radars, satellite observations and higher-resolution numerical models should strengthen India’s ability to forecast complex multi-cyclone interactions in a warming ocean.

Official / authoritative source: India Meteorological Department (IMD); MAUSAM journal; Ministry of Earth Sciences.

“Tundra regions are ecologically fragile but economically important.” Examine critically.

Value Addition

Tundra is a treeless cold biome characterised by permafrost, short growing seasons and very slow ecological recovery, yet it contains major energy, mineral, fisheries and transport resources.

KEYWORDS Permafrost • Arctic amplification • Carbon sink • Positive feedback • Resource frontier • Cryosphere • Carrying capacity

• Low temperatures and slow soil formation make vegetation recovery extremely slow after disturbance.

• Permafrost thaw can release CO2 and methane, reinforcing global warming through positive feedback.

• Tundra regions contain hydrocarbons, nickel, copper and other critical minerals.

• Arctic fisheries, reindeer herding and emerging seasonal shipping routes add economic significance.

DATA / FACT: Permafrost underlies roughly one-fourth of exposed land in the Northern Hemisphere and stores extremely large quantities of organic carbon.

CASE STUDY / EXAMPLE: Yamal Peninsula, Russia: large-scale gas development coexists with the traditional reindeer-herding landscape of the Nenets.

QUOTE / USE AS LINE: Use as line: “What makes the tundra economically valuable also makes its disturbance globally consequential.”

FUTURE-ORIENTED CONCLUSION: India’s Arctic Policy should prioritise scientific research, climate cooperation and responsible resource governance because Arctic change can influence the global climate system, the Himalayas and monsoon-linked processes.

Official / authoritative source: Ministry of Earth Sciences – India’s Arctic Policy; IPCC; National Centre for Polar and Ocean Research.

Discuss the role of aeolian processes in desertification and land degradation.

Value Addition

Aeolian processes – wind erosion, transport and deposition – are natural geomorphic processes, but vegetation loss and unsustainable land use can turn them into powerful drivers of dryland degradation.

KEYWORDS Deflation • Abrasion • Saltation • Suspension • Dune migration • Topsoil loss • Desertification feedback

• Deflation removes fine, nutrient-rich topsoil and reduces fertility and water-holding capacity.

• Saltating sand grains damage seedlings and loosen more soil particles, reinforcing erosion.

• Abrasion damages crops and exposed surfaces; deposition can bury fields, roads and canals.

• Overgrazing, deforestation, excessive tillage and drought amplify wind action.

DATA / FACT: SAC-ISRO’s Desertification and Land Degradation Atlas 2021 estimated 97.85 million ha – 29.77% of India’s geographical area – under land degradation/desertification processes in 2018-19.

CASE STUDY / EXAMPLE: Shelterbelts and afforestation in the Thar Desert reduce wind speed, trap moving sand and protect farms and infrastructure.

QUOTE / USE AS LINE: Use as line: “Desertification is often the degradation of productive drylands, not simply the outward march of a desert.”

FUTURE-ORIENTED CONCLUSION: India’s target of restoring 26 million hectares of degraded land by 2030 should combine shelterbelts, agroforestry, watershed management and climate-resilient land use to advance Land Degradation Neutrality.

Official / authoritative source: SAC-ISRO – Desertification and Land Degradation Atlas of India 2021; MoEFCC; UNCCD.

“Water resources are both an asset and a source of conflict in South Asia.” Examine with examples.

Value Addition

South Asia is marked by hydrological interdependence: transboundary rivers support food, energy and livelihoods, but upstream-downstream asymmetry, seasonal scarcity and geopolitics also make them conflict-prone.

KEYWORDS Hydro-diplomacy • Transboundary rivers • Upstream–downstream asymmetry • Water security • Benefit sharing • Integrated basin management

• River systems sustain irrigation, food security, hydropower, navigation, fisheries and groundwater recharge.

• Unequal geography creates disputes over lean-season flows, dams, storage and flood management.

• Climate change, glacial change and extreme rainfall increase uncertainty and bargaining pressure.

• Cooperative river projects can create energy and economic interdependence rather than zero-sum conflict.

DATA / FACT: CWC estimates India’s average annual water availability at about 2,115.95 BCM, but utilizable water at about 1,137 BCM; per-capita availability is projected to decline further.

CASE STUDY / EXAMPLE: Indus – India/Pakistan; Teesta – India/Bangladesh; Koshi/Gandak – India/Nepal; India–Bhutan hydropower cooperation is a positive benefit-sharing model.

QUOTE / USE AS LINE: Use as line: “Rivers ignore political boundaries, while water politics does not.”

FUTURE-ORIENTED CONCLUSION: Under Neighbourhood First, South Asia should move from dividing cubic metres of water to basin-wide benefit sharing, climate-resilient infrastructure and real-time hydrological data exchange, advancing SDG 6.

Official / authoritative source: Central Water Commission / Ministry of Jal Shakti; Ministry of External Affairs.

Unity in diversity remains the defining feature of Indian society despite communalism and regionalism. Comment.

Value Addition

India’s unity is based less on cultural uniformity and more on constitutional and federal accommodation of multiple languages, religions, regions and social identities.

KEYWORDS Pluralism • Composite culture • Constitutional patriotism • Fraternity • Cooperative federalism • Accommodation • Syncretism

• Single citizenship, universal franchise, Fundamental Rights and an independent judiciary create a common political framework.

• Federalism and linguistic states accommodate regional identities without demanding cultural assimilation.

• Mobility, markets, education, cinema, sports and digital networks create everyday interdependence.

• Communal polarisation, regional inequality, sons-of-the-soil politics and resource disputes remain serious stresses.

DATA / FACT: Census 2011 classified 121 languages in India; 22 languages are recognised in the Eighth Schedule.

CASE STUDY / EXAMPLE: Linguistic reorganisation after 1956 shows that democratic recognition of regional identity can strengthen rather than weaken national integration.

QUOTE / USE AS LINE: Nehru: “India is a geographical and economic entity, a cultural unity amidst diversity.”

FUTURE-ORIENTED CONCLUSION: Ek Bharat Shreshtha Bharat, cooperative federalism and equitable regional development must deepen fraternity so that diversity becomes a source of national confidence rather than political fragmentation.

Official / authoritative source: Census of India 2011; Constitution of India; Ministry of Education / Ek Bharat Shreshtha Bharat.

How do you understand disability? Substantiate the need for an inclusive policy framework in India.

Value Addition

The social model of disability views disability as the interaction of an impairment with physical, institutional, digital and attitudinal barriers – shifting policy from charity to rights and participation.

KEYWORDS Social model • Reasonable accommodation • Universal design • Accessibility • Substantive equality • Dignity • Assistive technology

• Inclusive education requires barrier-free campuses, accessible learning material, sign language and assistive technology.

• Employment inclusion needs accessible recruitment, workplace accommodation and skills support.

• Accessible transport, public buildings, websites and digital authentication are essential for equal citizenship.

• Policy must include persons with disabilities in design and decision-making: “Nothing about us without us.”

DATA / FACT: Census 2011 counted about 2.68 crore persons with disabilities (2.21%); the RPwD Act 2016 expanded recognised categories from 7 to 21 and provides 4% reservation in government jobs for benchmark disabilities.

CASE STUDY / EXAMPLE: Sugamya Bharat / Accessible India Campaign focuses on accessible built environment, transport and information-communication systems; UDID aims to standardise disability identification.

QUOTE / USE AS LINE: “Nothing about us without us.” – globally used disability-rights principle.

FUTURE-ORIENTED CONCLUSION: A Viksit Bharat 2047 must move from welfare to capability: universal design, accessible digital public infrastructure, reasonable accommodation and meaningful representation should make inclusion a default feature of governance.

Official / authoritative source: Department of Empowerment of Persons with Disabilities; RPwD Act 2016; Census of India.

Q10

Do you think digital technology promotes social empowerment? Explain with examples.

Value Addition

Digital technology promotes social empowerment when connectivity expands real capabilities – access to finance, welfare, education, health, information and public voice – rather than remaining mere device ownership.

KEYWORDS Digital Public Infrastructure • Digital inclusion • Capability approach • Last-mile delivery • Financial inclusion • Digital divide • e-Governance

• UPI and digital payments reduce transaction costs and bring small merchants into formal finance.

• DBT can reduce intermediaries and improve the speed and traceability of welfare transfers.

• DIKSHA, SWAYAM and e-Sanjeevani widen access to education and healthcare.

• Empowerment is limited by gender, rural-urban, language and disability divides, along with cyber fraud and misinformation.

DATA / FACT: TRAI reported roughly 1.09 billion internet subscribers in India by March 2026, illustrating the scale of digital reach.

CASE STUDY / EXAMPLE: PM-SVANidhi combines formal credit with incentives for digital transactions, helping street vendors build transaction histories and financial inclusion.

QUOTE / USE AS LINE: Use as line: “Connectivity creates access; capability converts access into empowerment.”

FUTURE-ORIENTED CONCLUSION: Digital India, BharatNet and inclusive Digital Public Infrastructure must follow an “inclusive by design” approach – multilingual, accessible, privacy-respecting and backed by offline alternatives – so digitisation does not create new exclusion.

Official / authoritative source: TRAI; MeitY – Digital India; DBT Bharat; NPCI; Ministry of Housing and Urban Affairs – PM-SVANidhi.

Q11

Vijayanagara architecture exemplifies the amalgamation of past traditions with contemporary practices. Elucidate.

Value Addition

Vijayanagara architecture combined the continuity of Dravidian temple traditions with imperial scale, commercial urbanism, hydraulic engineering and selective Indo-Islamic features.

KEYWORDS Raya Gopuram • Mandapa • Composite pillars • Sacred–secular synthesis • Bazaar streets • Hydraulic architecture • Indo-Islamic synthesis

• Traditional Dravidian elements included towering gopurams, temple tanks, enclosed complexes and pillared mandapas.

• Temple-linked bazaars and ceremonial streets reflected commercial expansion and state-sponsored festival culture.

• Musical/composite pillars and monumental complexes expressed imperial innovation.

• Lotus Mahal, Elephant Stables and other secular structures display arcuate and Indo-Islamic influences.

DATA / FACT: UNESCO identifies more than 1,600 surviving remains in the Hampi landscape.

CASE STUDY / EXAMPLE: Vitthala Temple – musical pillars and stone chariot; Hazara Rama – narrative reliefs; Lotus Mahal/Elephant Stables – cross-cultural secular design; Virupaksha – living sacred continuity.

QUOTE / USE AS LINE: Use as line: “Vijayanagara borrowed without losing its architectural identity.”

FUTURE-ORIENTED CONCLUSION: ASI–UNESCO conservation should combine structural preservation, digital documentation and carrying-capacity-based tourism so Hampi becomes a model of heritage-led sustainable development.

Official / authoritative source: Archaeological Survey of India; UNESCO World Heritage Centre; NCERT.

Q12

Linguistic reorganization of Indian States was driven by popular pressure from below. Comment.

Value Addition

Post-independence leaders initially feared that linguistic states could fragment the Union, but sustained grassroots mobilisation pushed the state towards democratic accommodation of linguistic identities.

KEYWORDS Sub-nationalism • Linguistic identity • Responsive federalism • Accommodation • Bottom-up federalism • State reorganisation

• The Dhar Commission and JVP Committee were initially cautious about reorganising states primarily by language.

• Potti Sriramulu’s fast and death triggered mass mobilisation for a Telugu-speaking state.

• Samyukta Maharashtra, Mahagujarat and Punjabi Suba movements similarly reflected bottom-up pressure.

• Language was important, but administrative viability, economy, geography and minority interests also influenced final boundaries.

DATA / FACT: Andhra State was created in 1953; the States Reorganisation Act, 1956 reorganised the map of India on a largely linguistic basis.

CASE STUDY / EXAMPLE: The Andhra movement after Potti Sriramulu’s death is the clearest example of popular pressure altering the Union government’s initial position.

QUOTE / USE AS LINE: Use as line: “Linguistic states regionalised administration without regionalising citizenship.”

FUTURE-ORIENTED CONCLUSION: India’s federal experience shows that recognising sub-national identity can strengthen the Union. Cooperative federalism and Ek Bharat Shreshtha Bharat should continue to reconcile regional pride with common citizenship.

Official / authoritative source: NCERT – Politics in India Since Independence; States Reorganisation Act 1956.

Q13

The model of planned economy was adopted in India to address regional imbalances left by colonial rule. Comment.

Value Addition

Colonial economic development created port-centred enclaves and spatially uneven infrastructure. Planning aimed to combine national growth with geographical redistribution of industry, irrigation and public investment.

KEYWORDS Balanced regional development • Mahalanobis strategy • Growth poles • Commanding heights • Spatial equity • Public-sector industrialisation

• The Second Five-Year Plan prioritised heavy industry and public-sector capital formation.

• Steel plants at Bhilai, Rourkela and Durgapur created industrial centres beyond older port cities.

• Bhakra-Nangal, Hirakud and DVC combined irrigation, power and regional development.

• Planning reduced some gaps, but Green Revolution concentration, governance differences and agglomeration effects produced persistent regional divergence.

DATA / FACT: Second Five-Year Plan: 1956-61; it marked the strongest early shift towards heavy-industry-led planned development.

CASE STUDY / EXAMPLE: Bhilai and Rourkela illustrate the use of large public-sector plants as regional growth poles; Freight Equalisation is often cited as a policy that diluted mineral-rich eastern states’ locational advantage.

QUOTE / USE AS LINE: Nehru famously described large dams as the “temples of modern India.”

FUTURE-ORIENTED CONCLUSION: The objective of balanced development continues through Aspirational Districts/Blocks and PM GatiShakti. Future regional policy must combine infrastructure with human capital, institutional capacity and local economic clusters.

Official / authoritative source: Planning Commission archives / Five-Year Plans; NITI Aayog; PM GatiShakti.

Q14

Compare the Loo, Chinook and Foehn winds with respect to region, nature and climatic impacts.

Value Addition

All three are warm, dry local winds, but the Loo is mainly a product of intense continental heating, whereas Chinook and Foehn are downslope winds warmed by adiabatic compression.

KEYWORDS Local winds • Adiabatic heating • Orographic effect • Rain shadow • Continental heating • Snow-eater • Heat stress

• Loo: hot, dry and often dusty summer wind over north and north-western India/Pakistan; causes heat stress and crop desiccation.

• Chinook: warm, dry downslope wind on the eastern Rockies of North America; rapid warming can melt snow.

• Foehn: warm, dry downslope wind of the Alps; causes snowmelt, drying and sometimes avalanche risk.

• Key distinction: Chinook/Foehn are orographic-adiabatic; Loo is predominantly thermally generated over a heated continental surface.

DATA / FACT: IMD notes that May temperatures exceed 40°C across large parts of northern India, creating the thermal environment associated with the Loo.

CASE STUDY / EXAMPLE: Chinook is popularly called a “snow-eater” because it can cause very rapid snowmelt on the leeward side of the Rockies.

QUOTE / USE AS LINE: Use as line: “Similar thermal effects can arise from very different atmospheric mechanisms.”

FUTURE-ORIENTED CONCLUSION: Mission Mausam and high-resolution local forecasts should improve heat-wave, mountain-wind and agricultural advisories as climate variability makes local wind impacts more consequential.

Official / authoritative source: India Meteorological Department; NCERT – Fundamentals of Physical Geography; Ministry of Earth Sciences.

Q15

Analyze the role of satellite-based technologies in climate-smart agriculture and food security in India.

Value Addition

Satellites provide repeated, synoptic and spatially consistent observations, enabling climate-smart agriculture to shift from reactive field assessment towards predictive, data-driven management.

KEYWORDS Remote sensing • GIS • SAR • Precision agriculture • Crop forecasting • Yield modelling • Agrometeorology • Decision support

• Satellite imagery maps crop acreage, crop type, vegetation health and cropping intensity.

• Soil-moisture, drought and flood maps support climate-risk management and irrigation decisions.

• Remote-sensing inputs can improve crop insurance verification, yield estimation and disaster-loss assessment.

• Combining satellites with AI, weather data and ground truthing improves farm-level advisories.

DATA / FACT: Under FASAL, satellite-based crop estimates cover 11 major crops across 20 states and 557 districts.

CASE STUDY / EXAMPLE: FASAL – crop forecasting; NADAMS – drought assessment; CHAMAN – horticulture; YES-TECH under PMFBY – technology-assisted yield estimation.

QUOTE / USE AS LINE: Use as line: “Satellite intelligence can convert agriculture from reactive management to predictive management.”

FUTURE-ORIENTED CONCLUSION: Digital Agriculture Mission, ISRO data, AI and local advisories should converge into an interoperable farm decision system that raises yields while reducing water, input use and climate risk.

Official / authoritative source: ISRO; Ministry of Agriculture & Farmers Welfare; PMFBY / FASAL programme documents.

Q16

“The centre of global trade is gradually shifting from the Atlantic region to the Indo-Pacific region.” Examine.

Value Addition

The shift is best understood as relative re-centring rather than replacement: the Atlantic remains financially important, while production, container traffic and manufacturing value chains are increasingly concentrated in Asia.

KEYWORDS Indo-Pacific • Global value chains • Factory Asia • Trade gravity • Maritime chokepoints • Blue economy • Supply-chain resilience

• China, Japan, Korea, ASEAN and India form a dense manufacturing and consumption network.

• Electronics, automobiles, semiconductors and machinery are deeply embedded in Asian value chains.

• The Indian Ocean and Strait of Malacca connect West Asian energy with South and East Asian markets.

• RCEP/CPTPP and regional production networks reinforce trade concentration, though US-EU demand and finance keep the Atlantic central.

DATA / FACT: UNCTAD reports that developing Asian ports handled about 60% of global container port traffic in 2024.

CASE STUDY / EXAMPLE: The Strait of Malacca is a critical Indo-Pacific chokepoint linking the Indian and Pacific Oceans and carrying major energy and merchandise flows.

QUOTE / USE AS LINE: Use as line: “The Atlantic remains a financial centre; the Indo-Pacific is increasingly a production-and-logistics centre.”

FUTURE-ORIENTED CONCLUSION: Sagarmala, Maritime India Vision, resilient supply chains and Indo-Pacific partnerships can position India not merely on trade routes but as a high-value manufacturing, logistics and maritime hub by 2047.

Official / authoritative source: WTO; UNCTAD; Ministry of Ports, Shipping and Waterways; Ministry of Commerce & Industry.

Q17

Analyze the major drivers of human-induced land-use changes in India and their geographical consequences.

Value Addition

India’s landscapes are being reshaped by urbanisation, infrastructure, mining, intensive agriculture, energy projects and tourism, altering hydrology, ecosystems and local climate.

KEYWORDS Land-use/land-cover change • Urban sprawl • Habitat fragmentation • Impervious surface • Ecological footprint • Landscape connectivity

• Peri-urban growth converts agricultural land, wetlands and commons into built-up areas.

• Highways, industrial corridors, mining and dams fragment landscapes and alter drainage.

• Agricultural intensification changes groundwater, soil health and biodiversity.

• Consequences include erosion, urban flooding, heat islands, groundwater stress and wildlife-corridor disruption.

DATA / FACT: SAC-ISRO estimated 29.77% of India’s geographical area under land degradation/desertification processes in 2018-19; ISFR 2023 reports forest and tree cover at 25.17%, showing aggregate gains can coexist with local ecological degradation.

CASE STUDY / EXAMPLE: Bengaluru’s conversion and constriction of lakes/wetlands and peri-urban land is frequently used to explain how built-up expansion increases flood vulnerability.

QUOTE / USE AS LINE: Use as line: “Land is not merely real estate; it is ecological infrastructure.”

FUTURE-ORIENTED CONCLUSION: PM GatiShakti’s geospatial planning, Green India Mission and land-restoration commitments should make ecological carrying capacity and landscape connectivity core inputs into infrastructure and urban decisions.

Official / authoritative source: SAC-ISRO; Forest Survey of India – ISFR 2023; PM GatiShakti.

Q18

Is caste disappearing in urban India? Illustrate your answer with examples.

Value Addition

Urbanisation weakens some ritual and occupational expressions of caste, but caste persists through marriage, social networks, housing, political mobilisation and access to social capital.

KEYWORDS De-ritualisation • Endogamy • Network caste • Caste–class intersection • Social capital • Identity politics • Social mobility

• Occupational mobility and anonymous workplaces weaken hereditary occupation and everyday ritual segregation.

• Endogamy remains a powerful mechanism for reproducing caste boundaries, including through digital matrimonial platforms.

• Caste associations can provide jobs, housing contacts, political mobilisation and community support in cities.

• Class can soften visible caste practices but does not automatically erase discrimination or inherited social capital.

DATA / FACT: Scheduled Castes constituted 16.6% of India’s population in Census 2011; continuing constitutional and welfare interventions underline the persistence of caste-linked disadvantage.

CASE STUDY / EXAMPLE: Government incentives for inter-caste marriage under the Dr Ambedkar social-integration framework recognise that marriage remains a major social boundary; caste filters on matrimonial platforms show “modern” mechanisms reproducing old endogamy.

QUOTE / USE AS LINE: B.R. Ambedkar: “Caste is not a division of labour; it is a division of labourers.”

FUTURE-ORIENTED CONCLUSION: The constitutional vision of Articles 14, 15 and 17 requires urbanisation to generate substantive equality, mixed social spaces and equal opportunity – moving India towards social mobility and fraternity, not merely spatial mobility.

Official / authoritative source: Census of India 2011; Ministry of Social Justice & Empowerment; Constitution of India.

Q19

Critically examine the challenges of demographic transition in contemporary India.

Value Addition

India has moved towards replacement-level fertility, making the central challenge less about population explosion and more about using the current working-age window while preparing for rapid ageing and regional divergence.

KEYWORDS Demographic dividend • Demographic window • Ageing • Dependency ratio • Feminisation of ageing • Regional divergence • Silver economy

• A large working-age population creates a time-bound opportunity, but only if enough productive jobs and skills exist.

• Lower fertility and longer life expectancy increase the future demand for pensions, geriatric care and long-term care systems.

• Southern and western states are ageing faster, while several northern states remain younger, increasing inter-state labour mobility.

• Smaller families and greater female employment may weaken traditional family-based elder-care arrangements.

DATA / FACT: NFHS-5 reported India’s TFR at 2.0. Official population projections indicate the 60+ population could rise from about 10 crore in 2011 to around 23 crore by 2036.

CASE STUDY / EXAMPLE: Kerala represents an advanced demographic transition: low fertility, high longevity and a rapidly growing elderly share, making it an early laboratory for India’s ageing challenge.

QUOTE / USE AS LINE: Use as line: “India must harvest its demographic dividend before the window becomes an ageing challenge.”

FUTURE-ORIENTED CONCLUSION: Skill India, quality jobs, higher female labour-force participation, portable social protection, geriatric health systems and the silver economy must convert today’s demographic dividend into long-term demographic security.

Official / authoritative source: MoHFW – NFHS-5; MoSPI – Population Projections / Youth in India; Ministry of Social Justice & Empowerment.

Q20

Evaluate the impact of globalization on Indian youths in social, political, economic and cultural spheres.

Value Addition

Globalisation reaches Indian youth through jobs, migration, smartphones, entertainment, consumption and political ideas, simultaneously expanding opportunity and creating new forms of insecurity and cultural pressure.

KEYWORDS Glocalisation • Cultural hybridisation • Gig economy • Digital cosmopolitanism • Brain circulation • Consumerism • Global citizenship

• Economic: IT/BPO, startups, remote work and global careers expand opportunity, but gig insecurity and skill obsolescence remain risks.

• Social: greater individual choice and changing gender norms coexist with consumerism, online comparison and digital isolation.

• Political: global debates on climate, gender and rights broaden awareness, while misinformation and echo chambers increase polarisation.

• Cultural: K-pop, OTT and global fashion coexist with regional-language content and local revival – a process of glocalisation rather than simple Westernisation.

DATA / FACT: PLFS 2023-24 placed unemployment among 15-29-year-olds at about 10.2%, illustrating that global integration does not automatically produce quality employment.

CASE STUDY / EXAMPLE: India’s startup and IT ecosystem shows “brain circulation”: global technology, capital and professional experience can generate indigenous firms, platforms and employment.

QUOTE / USE AS LINE: Use as line: “Globalisation need not produce homogenisation; it can also generate glocalisation.”

FUTURE-ORIENTED CONCLUSION: Viksit Bharat 2047 must equip the Amrit Peedhi with global skills, entrepreneurship, digital literacy and cultural confidence so young Indians become creators of globalisation rather than only consumers of it.
