Question 1 (50 marks)
Q1(a) · The Earth's Interior and Tectonics · 10 marks≈ 7 min
Volcanicity, Earthquakes and Tsunamis
Write a note on pseudovolcanic features.
हिंदी में प्रश्न
कूटज्वालामुखीय लक्षणों पर टिप्पणी लिखिए।
Model answer
Paper and question: Paper I, Q1(a)
Approach: Define pseudovolcanic features as volcano-like forms produced by non-volcanic processes, then describe the main types (mud volcanoes, impact craters, cryptovolcanic structures, liquefaction sand blows, gas-blowout craters) with Indian and world examples; sketch one.
Pseudovolcanic features are landforms that look like volcanic cones or craters but are not produced by the eruption of magma. Their resemblance often misled early observers.
(i) Mud volcanoes: cones built by mud, water and methane forced up from pressurised sediments, common in tectonically squeezed basins: Baratang Island in the Andamans, the Makran coast and Azerbaijan.
(ii) Impact craters: circular depressions with raised rims formed by meteorite impact, such as Lonar Lake in the Deccan basalt of Maharashtra and Barringer (Meteor) Crater in Arizona.
(iii) Cryptovolcanic structures: circular disturbed structures once attributed to hidden volcanic explosions; many, such as the Ries basin in Germany, are now recognised as impact structures.
(iv) Sand blows or sand volcanoes, small cones formed when earthquake shaking liquefies saturated sand, as in Kutch in 2001; and gas-blowout craters, such as those found in Siberia's Yamal peninsula since 2014.
Diagram: Section of a mud volcano showing pressurised clay and gas rising along a fault to build a cone, beside an impact crater with raised rim and breccia.
Distinguishing them matters: shocked quartz marks impacts, while methane in mud volcanoes signals hydrocarbon reservoirs below.Q1(b) · Oceanography · 10 marks≈ 7 min
Marine Resources, Coral Reefs and Sea-level Change
Distinguish between low energy coasts and coral coasts.
हिंदी में प्रश्न
निम्न ऊर्जा तटों तथा प्रवाल तटों के मध्य विभेद कीजिए।
Model answer
Paper and question: Paper I, Q1(b)
Approach: Define each coast type and distinguish them on setting, energy, processes, landforms and examples (Indian and world); draw contrasting coastal profiles.
Low energy coasts are sheltered coasts where small waves and gentle currents bring little energy, so deposition exceeds erosion. Coral coasts are tropical coasts built or fringed by coral reefs, formed by living organisms.
Setting: low energy coasts occur in sheltered bays, estuaries, lagoons and inland seas at any latitude, often with large tidal ranges; coral coasts are confined to warm (about 20–29 °C), clear, shallow, saline tropical seas, mostly between 30° N and 30° S, on the eastern margins of oceans.
Processes: low energy coasts are shaped by deposition of fine silt and clay by rivers and tides; coral coasts by biological growth of reef organisms and the breaking of waves on reef fronts.
Landforms: low energy coasts have mudflats, salt marshes, mangrove swamps and deltas, as in the Sundarbans and the Gulf of Kachchh; coral coasts have fringing and barrier reefs, atolls and lagoons, as in the Gulf of Mannar, Lakshadweep and the Great Barrier Reef.
Diagram: Two profiles: a gently sloping muddy shore with mangroves, and a reef coast with lagoon and reef crest absorbing waves.
Reefs themselves create low energy lagoons behind them.Q1(c) · Climatology: Atmosphere and Circulation · 10 marks≈ 7 min
Atmospheric Stability, Air Masses and Frontogenesis
Discuss the impacts of ocean currents on air mass behaviour.
हिंदी में प्रश्न
वायु संहति के व्यवहार पर महासागरीय धाराओं के प्रभावों की विवेचना कीजिए।
Model answer
Paper and question: Paper I, Q1(c)
Approach: Explain that ocean currents modify the temperature, moisture and stability of air masses above them; contrast warm and cold currents with named examples and add the meeting zones. Draw a world sketch map of the main warm and cold currents with the air mass effect.
Air masses take on the properties of the surfaces they cross. Ocean currents, by changing sea surface temperature, modify the temperature, moisture and stability of the air above them.
Warm currents: they heat and moisten the lower air, making it unstable and rain-bearing. The Gulf Stream warms cold cP air flowing off North America, causing rapid cyclone development along the east coast; the North Atlantic Drift keeps mP air over north-west Europe mild in winter; the Kuroshio gives humid conditions to Japan.
Cold currents: they cool the lower air from below, producing an inversion and stable air that does not rise. Fog forms but rain is scarce, contributing to coastal deserts: the Atacama with the Humboldt (Peru) current, the Namib with the Benguela current, and the summer fogs of San Francisco with the California current.
Map: World outline marking the Gulf Stream, Kuroshio, Humboldt, Benguela, California and Labrador currents, with the Atacama and Namib deserts and the Grand Banks fog zone.
Where warm and cold currents meet, as the Gulf Stream and Labrador current off Newfoundland, dense advection fog forms.
Ocean currents thus reshape air mass behaviour.Q1(d) · Environmental Geography · 10 marks≈ 7 min
Ecosystems, Ecological Imbalances and Environmental Degradation
Describe the characteristics of biological deserts.
हिंदी में प्रश्न
जैविक मरुस्थलों के लक्षणों का वर्णन कीजिए।
Model answer
Paper and question: Paper I, Q1(d)
Approach: Define biological deserts as areas of very low biological productivity, describe their characteristics, and give natural and human-made examples on land and sea. A world map of ocean gyres and dead zones supports the answer.
A biological desert is an area where biological productivity and species diversity are extremely low because one or more limiting factors (water, nutrients, light, temperature or oxygen) are severely deficient.
Characteristics: (i) very low net primary productivity; (ii) few species and simple, short food chains; (iii) a strong limiting factor; (iv) low biomass and slow nutrient cycling; (v) slow recovery after disturbance.
Natural examples: the centres of subtropical ocean gyres, such as the South Pacific Gyre, are oligotrophic: warm, stratified surface water blocks the upwelling of nutrients, so plankton is scarce. Hyper-arid deserts such as the Atacama, and the ice sheets of Antarctica and Greenland, are their land equivalents.
Human-made examples: fertiliser runoff creates oxygen-starved dead zones, as in the Gulf of Mexico and the Baltic Sea; heavily polluted river stretches such as the Yamuna in Delhi support little aquatic life; extensive monoculture plantations are often called 'green deserts'.
Map: World map shading the five subtropical gyres and marking the Atacama, Antarctica, the Gulf of Mexico and Baltic dead zones.
Recognising biological deserts helps target pollution control, nutrient management and restoration of degraded ecosystems.Q1(e) · Climatology: Weather Systems, Climates and Climate Change · 10 marks≈ 7 min
Global Climate Change, Applied and Urban Climatology
Explain the concept of micro carbon sink and its relevance.
हिंदी में प्रश्न
सूक्ष्म कार्बन सिंक की संकल्पना एवं इसकी प्रासंगिकता की व्याख्या कीजिए।
Model answer
Paper and question: Paper I, Q1(e)
Approach: Explain micro carbon sinks as small, local stores that absorb and hold carbon (trees outside forests, urban green spaces, wetlands, farm soils, sacred groves; at the smallest scale, microbial carbon storage), then their relevance for climate mitigation and India's NDC; add a simple diagram.
A carbon sink is any reservoir that absorbs more carbon than it releases, such as forests, oceans and soils. A micro carbon sink is a small, local sink: individual trees and village woodlots, urban parks and green roofs, small wetlands and ponds, mangrove patches, sacred groves, and agricultural soils enriched by organic farming, agroforestry or biochar. At the smallest scale, soil microbes and ocean microbes (the 'microbial carbon pump') lock carbon into stable forms.
Relevance: (i) together they store significant carbon and can be created almost anywhere, including cities and farms; (ii) they support India's NDC target of an additional carbon sink of 2.5–3 billion tonnes of CO₂ equivalent through forest and tree cover by 2030; (iii) they bring co-benefits: cooler cities, groundwater recharge, soil fertility and biodiversity; (iv) they involve communities, as in Nagar Van urban forests, green belts and farm agroforestry.
Diagram: A village–city landscape showing trees, ponds, green roofs and farm soils absorbing CO₂ arrows.
Micro sinks cannot replace emission cuts, but they are a low-cost, local complement to them.
Question 2 (50 marks)
Q2(a) · Climatology: Atmosphere and Circulation · 20 marks≈ 14 min
Atmospheric Circulation, Planetary and Local Winds
Discuss the forces which govern the air movement on the Earth's surface.
हिंदी में प्रश्न
धरातल पर वायु गति को नियंत्रित करने वाले बलों की विवेचना कीजिए।
Model answer
Paper and question: Paper I, Q2(a)
Approach: Discuss each force that governs horizontal air movement (pressure gradient, Coriolis, friction, centripetal acceleration, with gravity for vertical motion) and how their combinations produce geostrophic, gradient and surface winds, with examples. Draw the force-balance diagrams.
Wind is air moving horizontally from high to low pressure. Its speed and direction are governed by a set of forces whose balance changes with height and latitude.
Pressure gradient force: the primary driving force, acting from high to low pressure at right angles to the isobars. The closer the isobars, the stronger the wind, as in the core of a tropical cyclone.
Coriolis force: an apparent force due to the earth's rotation, described by Coriolis (1835) and applied to winds by Ferrel. It deflects moving air to the right in the northern hemisphere and to the left in the southern, changes direction but not speed, and is proportional to wind speed and the sine of latitude. It is zero at the equator, which is why tropical cyclones rarely form within about 5° of it.
Friction: the surface slows wind in the lowest 1–2 km. Slower wind means a weaker Coriolis force, so surface winds cross isobars at an angle towards low pressure, more over land than over sea.
Centripetal acceleration: where isobars are curved, a net inward force keeps air moving around lows and highs, producing anticlockwise inflow into cyclones and clockwise outflow from anticyclones in the northern hemisphere.
Gravity holds the atmosphere to the earth and, balanced against the vertical pressure gradient, keeps it in hydrostatic equilibrium, governing vertical motion.
Diagram: Three panels: geostrophic wind parallel to straight isobars with balanced pressure gradient and Coriolis arrows; gradient wind around a low; surface wind crossing isobars with friction arrow.
Resulting winds: the geostrophic wind (pressure gradient = Coriolis) aloft, the gradient wind along curved isobars, and the surface wind modified by friction. Their combination explains the trades, westerlies and cyclonic flows, summarised in Buys Ballot's law (1857).
These forces together turn the simple high-to-low flow into the complex global circulation.Q2(b) · Geomorphic Processes and Landscape Development · 15 marks≈ 11 min
Denudation Chronology, Erosion Surfaces and Slope Development
"The knowledge of slope analysis has limited field application in the slope management." Explain.
हिंदी में प्रश्न
"ढाल प्रबंधन में ढाल विश्लेषण के ज्ञान का सीमित क्षेत्रीय उपयोग है।" व्याख्या कीजिए।
Model answer
Paper and question: Paper I, Q2(b)
Approach: Explain what slope analysis covers, show where it helps slope management, then explain why its field application is limited, and give a balanced conclusion with Indian examples; sketch a slope profile with units and a hazard map legend.
Slope analysis studies the angle, length, form and evolution of hillslopes — through slope maps (Wentworth’s method), morphological mapping, profile surveys, and models of slope evolution by Davis (decline), Penck (replacement), Wood and King (parallel retreat), and the nine-unit land-surface model of Dalrymple, Blong and Conacher (1968).
Uses in management: slope classes guide land capability, terracing and contour bunding; slope is a core input of landslide hazard zonation (for example under IS 14496 Part 2) and of road and building codes in hill towns.
Why application is limited: (i) slope angle alone does not decide stability — lithology, joints, weathering depth, pore-water pressure, vegetation and seismicity matter as much; (ii) theoretical models describe long-term evolution over millennia, not stability over years; (iii) slope maps are generalised at small scales, while failures are site-specific; (iv) data on soil strength and groundwater are scarce; (v) human cutting, loading and drainage changes alter slopes faster than models predict.
Evidence: the Joshimath subsidence (2023), on old landslide debris, and repeated failures along Himalayan highways show that slope maps without geotechnical and hydrological data mislead.
Diagram: Hillslope profile with Dalrymple units (interfluve, convex creep slope, fall face, transportational midslope, colluvial footslope, channel bed) and a three-class hazard legend.
The statement is therefore partly true: slope analysis is necessary but not sufficient. Integrated with geology, hydrology, GIS and monitoring, it becomes a strong tool for slope management.Q2(c) · Oceanography · 15 marks≈ 11 min
Ocean Bottom Topography and Ocean Deposits
Describe the configuration of the Pacific Ocean floor.
हिंदी में प्रश्न
प्रशान्त महासागर के तल के संविन्यास का वर्णन कीजिए।
Model answer
Paper and question: Paper I, Q2(c)
Approach: Describe the configuration (arrangement and shape) of the Pacific floor zone by zone, contrasting the western and eastern sides; draw an east–west profile from Japan to Peru.
The Pacific Ocean is roughly triangular, wide in the south and narrowing to the Bering Strait. Its configuration is asymmetric: an active western margin of arcs and seas and a narrow eastern margin facing young mountains.
Western margin: a festoon of island arcs, from the Aleutians, Kurils and Japan to the Philippines and New Zealand, encloses marginal seas. Seaward of the arcs lie deep trenches: Mariana (Challenger Deep, nearly 11,000 m), Japan, Kuril, Tonga and Kermadec.
Eastern margin: the shelf is very narrow off the Andes and the Rockies; the Peru–Chile and Middle America trenches lie close to the coast, and there are no large marginal seas.
Central zone: the East Pacific Rise, a broad, gentle and fast-spreading ridge, runs off-centre near the east, from the Gulf of California to the south-east Pacific, offset by long fracture zones.
Deep basins: west of the rise lies the vast central floor at 4,000–6,000 m, with abyssal hills more common than flat plains, because sediment is trapped in trenches.
Islands and seamounts: volcanic chains such as Hawaii and the Society Islands, numerous guyots in the western Pacific, and coral atolls of Micronesia and Polynesia rise from this floor.
Diagram: East–west profile from Japan to Peru showing marginal sea, island arc, trench, deep basin with seamounts, the East Pacific Rise and the Peru–Chile Trench beside the Andes.
This configuration reflects a plate system in which old, cold crust sinks in the west and new crust forms in the east.
Question 3 (50 marks)
Q3(a) · Climatology: Weather Systems, Climates and Climate Change · 20 marks≈ 14 min
Global Climate Change, Applied and Urban Climatology
"Climate change is a reality." Explain with suitable examples.
हिंदी में प्रश्न
"जलवायु परिवर्तन एक वास्तविकता है।" उचित उदाहरणों द्वारा व्याख्या कीजिए।
Model answer
Paper and question: Paper I, Q3(a)
Approach: Explain, with evidence and examples, that climate change is real: instrumental warming, greenhouse gas rise, cryosphere and sea level, extremes, ecological signals and Indian evidence, then address natural variability versus human attribution (IPCC) and conclude; add a graph of temperature and CO₂.
Climate change means a long-term shift in average weather conditions. Its reality rests on multiple, independent lines of evidence, and the IPCC Sixth Assessment Report (2021) states that it is unequivocal that human influence has warmed the atmosphere, ocean and land.
Temperature and greenhouse gases: global surface temperature has risen about 1.1°C since 1850–1900. Carbon dioxide measured at Mauna Loa since 1958 (the Keeling curve) has climbed from about 315 ppm to over 420 ppm, far above the pre-industrial level of about 280 ppm.
Cryosphere and sea: mountain glaciers are retreating, among them the Gangotri glacier, the source of the Bhagirathi; Arctic summer sea ice has declined sharply since satellite records began in 1979; and sea level is rising faster, threatening low islands such as the Lakshadweep and the Sundarbans.
Extreme events: heat waves, intense rainfall and droughts are becoming more frequent and severe, for example the Uttarakhand floods (2013), Chennai floods (2015) and European heat wave (2003), and attribution studies link many such events to warming.
Ecological signals: earlier flowering and bird migration, species moving upslope and poleward, and repeated coral bleaching on the Great Barrier Reef (2016, 2017) and in the Gulf of Mannar.
Diagram: Graph of global temperature anomaly and atmospheric CO₂ from 1880 to the present, both rising steeply after 1950.
Climate has always changed naturally through Milankovitch cycles, solar variation and volcanoes, but these cannot explain the present rate and pattern of warming, such as a warming lower atmosphere with a cooling stratosphere, which fits greenhouse forcing. Climate change is therefore a measurable reality, and the Paris Agreement (2015) reflects the global response.Q3(b) · Biogeography · 15 marks≈ 11 min
Soil Genesis, Profile, Classification and Distribution
Distinguish between the characteristics of Chernozem and Sierozem soils.
हिंदी में प्रश्न
चर्नोज़ेम एवं सिरोज़ेम मृदाओं के लक्षणों में अंतर स्पष्ट कीजिए।
Model answer
Paper and question: Paper I, Q3(b)
Approach: Introduce both as pedocals of the dry mid-latitudes, then contrast climate, vegetation, profile, chemistry, distribution and use point by point; draw the two profiles side by side.
Chernozem and Sierozem are both zonal pedocals formed by calcification, where evaporation exceeds rainfall and calcium carbonate collects in the profile. They differ because one forms under grass in a sub-humid steppe and the other under sparse shrubs in a semi-desert.
Chernozem (Russian for black earth): found in the steppes of Ukraine, southern Russia and northern Kazakhstan and the prairies of the USA and Canada. Dense grass roots give a thick, black, humus-rich A horizon with crumb structure, a calcium carbonate layer lower down, near-neutral pH and high base saturation. These are among the world’s most fertile soils and carry the great wheat belts.
Sierozem (grey earth): found in the semi-deserts of Central Asia (Uzbekistan, Turkmenistan), Iran and the Great Basin of the USA. Scanty shrubs give little humus, so the soil is thin, light grey and loose; carbonate and sometimes gypsum lie close to the surface, pH is alkaline and salts build up. Farming needs irrigation, as with cotton on the Amu Darya and Syr Darya, which helped shrink the Aral Sea.
Diagram: Two profiles: Chernozem with a black A of about 1 m over a white carbonate band; Sierozem with a thin grey A over a shallow carbonate layer and a salt crust.
In short, Chernozem shows grassland abundance and Sierozem desert scarcity.Q3(c) · Biogeography · 15 marks≈ 11 min
World Distribution of Plants and Animals; Gene Pool Centres
Give a classification of plants based on the amount of water requirement.
हिंदी में प्रश्न
जल की मात्रा की आवश्यकता के आधार पर पादपों का वर्गीकरण कीजिए।
Model answer
Paper and question: Paper I, Q3(c)
Approach: Give Warming’s classification of plants by water need and describe each group with adaptations and Indian examples; draw a moisture gradient diagram from water to desert.
Water is the most decisive factor in plant form. The Danish botanist Eugenius Warming, in his Oecology of Plants (1895, English edition 1909), grouped plants by their water relations, a scheme still used in biogeography.
Hydrophytes grow in or on water: submerged (Hydrilla, Vallisneria), free-floating (water hyacinth, Pistia), rooted with floating leaves (lotus, water lily) and emergent (Typha). They have little supporting tissue, air spaces for buoyancy and reduced roots, as in Dal Lake and the Loktak phumdis.
Mesophytes need moderate, steady moisture: most crops and trees such as mango, sal and neem, with well-developed roots, broad leaves and stomata on the lower surface.
Xerophytes survive drought: ephemerals that complete life after rain, succulents such as Opuntia and Euphorbia that store water, and hardy shrubs such as Acacia, Prosopis and Calotropis with deep roots, thick cuticles, sunken stomata and small or spiny leaves, as in the Thar.
Halophytes tolerate salt, like the mangroves Rhizophora and Avicennia of the Sundarbans and Suaeda of the Rann of Kachchh. Tropophytes change with the seasons, behaving as mesophytes in the rains and xerophytes in the dry season, like teak, which sheds leaves.
Diagram: A horizontal gradient from open water to desert showing submerged, floating and emergent hydrophytes, a marsh, mesophytic forest, tropophytic deciduous forest and xerophytic scrub, with a saline coast branch for halophytes.
This classification explains vegetation zones and helps choose species for afforestation and dryland farming.

Q4(a) · Geomorphic Processes and Landscape Development · 20 marks≈ 14 min
Geomorphic Cycles and Landscape Development (Davis, Penck, King)
Discuss the concept of Periglacial cycle as propounded by Peltier.
हिंदी में प्रश्न
पेल्टियर द्वारा प्रतिपादित परिहिमानी चक्र की संकल्पना का विवेचन कीजिए।
Model answer
Paper and question: Paper I, Q4(a)
Approach: Introduce Peltier’s climatic geomorphology and morphogenetic regions, describe the stages of the periglacial cycle with processes and landforms, give present and relict examples, and critically assess the model; draw the stage profiles.
Louis C. Peltier (1950) argued that Davis’s ‘normal’ humid cycle cannot explain landscapes shaped under cold climates. He divided the world into nine morphogenetic regions on the basis of mean annual temperature and rainfall, and proposed a separate cycle for the periglacial region, where frost action and mass movement replace running water as the dominant agents.
Processes: freeze–thaw (frost wedging) shatters exposed rock; solifluction moves the saturated active layer over permafrost; nivation deepens snow-patch hollows; meltwater is seasonal and weak.
Initial stage: a pre-existing fluvial landscape of valleys and convex–concave slopes comes under a periglacial climate when ice retreats or the climate cools.
Youth: intense frost weathering attacks summits and free faces, producing block fields (felsenmeer) and talus; solifluction carries debris to valley floors, which begin to fill.
Maturity: summits are lowered and slopes retreat and flatten; cryoplanation (altiplanation) benches develop; valleys are choked with solifluction debris, so relief falls by summit lowering and valley filling together.
Old age: a subdued surface of low, rounded or tor-crowned summits and smooth debris-mantled slopes results. When the climate warms, rivers resume work and incise the debris fills.
Diagram: Four cross-profiles (initial, youth, maturity, old age) showing frost-shattered summits, block fields, solifluction lobes, cryoplanation benches and filled valleys.
Examples: active periglacial landscapes in Siberia, Alaska and northern Canada, and in India in the high cold desert of Ladakh with patterned ground and rock glaciers; relict ‘head’ deposits and chalk coombes in southern England record Pleistocene periglaciation.
Assessment: Peltier pioneered climatic geomorphology, but the model inherits Davis’s weaknesses — assumed stillstand, little field measurement of process rates, and climates that rarely last long enough for a full cycle. Later workers such as H.M. French regard most periglacial landscapes as polygenetic. The cycle remains a useful framework for interpreting cold-climate relief.Q4(b) · Geomorphic Processes and Landscape Development · 15 marks≈ 11 min
Channel Morphology and Fluvial Landforms
"Climate, slope gradient and rock structure influence the avulsion of channels." Explain.
हिंदी में प्रश्न
"जलवायु, ढाल प्रवणता तथा शैल संरचना चैनलों के भू-अपदारण को प्रभावित करते हैं।" व्याख्या कीजिए।
Model answer
Paper and question: Paper I, Q4(b)
Approach: Define avulsion and its mechanism (superelevation, gradient advantage, trigger), then explain the influence of climate, slope gradient and rock structure in turn with Kosi, Brahmaputra and Huang He examples; draw a plan of successive Kosi courses or a superelevated channel section.
Avulsion is the relatively sudden abandonment of a river channel in favour of a new course on its floodplain, fan or delta. It needs a setup — the channel bed and levees aggrade above the surrounding plain (superelevation), so a new path offers a steeper gradient — and a trigger, usually a major flood or a levee breach.
Climate: high and variable discharge drives avulsion. Monsoon floods, cloudbursts and glacial melt deliver large water and sediment loads in short periods; heavy sediment supply from the Himalaya makes the Kosi, Gandak and Tista aggrade fast.
Slope gradient: avulsion is common where gradient drops suddenly, as at mountain fronts and on fans and deltas, causing rapid deposition. The Kosi has shifted more than 100 km westward across its megafan over the last two centuries, and its 2008 breach at Kusaha re-occupied an old eastern course.
Rock structure and tectonics: active faults, tilting and subsidence guide rivers towards sinking blocks; the late eighteenth-century shift of the Brahmaputra into the Jamuna course in Bangladesh is often linked to tectonic movement and floods. Erodible banks and buried channels in unconsolidated alluvium ease avulsion, whereas resistant rock confines rivers.
Diagram: Plan of successive courses of the Kosi on its megafan, with a cross-section of a superelevated channel above the floodplain.
Embankments and barrages can delay avulsion but raise the bed and the eventual risk. Avulsion thus results from climate, slope and structure acting together.Q4(c) · Environmental Geography · 15 marks≈ 11 min
Environmental Hazards, Policy, Education and Legislation
Discuss the Perception, Attitude, Value and Emotion (PAVE) Theory of environmental management.
हिंदी में प्रश्न
पर्यावरणीय प्रबंधन में प्रत्यक्ष ज्ञान, अभिवृत्ति, मान एवं संवेग (PAVE) सिद्धांत की विवेचना कीजिए।
Model answer
Paper and question: Paper I, Q4(c)
Approach: Present PAVE as a behavioural theory of environmental management, explain each component with examples, show how managers apply it and give a critique; draw a box diagram from the four components to behaviour and environmental outcome.
The PAVE theory of environmental management holds that environmental problems are rooted in human behaviour, and behaviour flows from four inner components: perception, attitude, value and emotion. It grew from behavioural geography, which, following Kirk's 'behavioural environment', studies the environment as perceived rather than as it objectively is.
Perception: the mental image of the environment and its risks. People often underestimate hazards, as Gilbert White's studies of floodplain dwellers showed, so correct perception is the first step to management.
Attitude: a learned tendency to respond favourably or unfavourably to an issue, such as willingness to segregate waste or resistance to a dam.
Value: deep beliefs about what is right, ranging from anthropocentric to ecocentric, as in Arne Naess's deep ecology; the religious values of the Bishnoi and of sacred groves sustain conservation.
Emotion: feelings of attachment, fear or anger that turn belief into action, as in the Chipko and Appiko movements.
Diagram: Four boxes, perception → attitude → value → emotion, leading to environmental behaviour and then to environmental outcome, with a feedback loop from outcome back to perception.
Application: managers use PAVE in participatory approaches such as Joint Forest Management, public hearings in environmental impact assessment, campaigns like Swachh Bharat and behavioural nudges. Critique: it underplays structural factors such as poverty, markets and power, and the value-action gap means attitudes do not always become action.

Radical, Behavioural, Humanistic and Welfare Approaches
Explain the concept of Time-Geography.
हिंदी में प्रश्न
समय-भूगोल की संकल्पना की व्याख्या कीजिए।
Model answer
Paper and question: Paper I, Q5(a)
Approach: Define time-geography with Hagerstrand's attribution, explain its basic concepts (path, prism, constraints) with a diagram and give applications.
Time-geography was developed by the Swedish geographer Torsten Hagerstrand at Lund, notably in his paper 'What about people in regional science?' (1970). It studies how individuals move through space and time, treating time as a scarce resource just like space.
Basic concepts: the space-time path traces a person's movement through the day in a three-dimensional diagram (two axes of space, one of time); the space-time prism shows all locations a person can reach within a given time budget and travel speed.
Hagerstrand identified three constraints: capability constraints (biological needs such as sleep, and means of transport), coupling constraints (the need to be with others at certain places and times, such as work or school) and authority constraints (rules, opening hours, access rights).
Diagram: Space-time aquarium: vertical time axis, horizontal map plane, a person's path from home to office to market and back, with a prism shape around it.
Applications include transport planning, women's mobility and accessibility studies, and GIS-based activity analysis; critics note it underplays meaning and power.Q5(b) · Economic Geography · 10 marks≈ 7 min
World Agriculture: Typology, Inputs and Productivity
"Whittlesey's agricultural regions are relevant even today." Discuss.
हिंदी में प्रश्न
"ह्विटल्सी के कृषि प्रदेश आज भी प्रासंगिक हैं।" विवेचना कीजिए।
Model answer
Paper and question: Paper I, Q5(b)
Approach: Recall Whittlesey's criteria and regions briefly, then show where they remain relevant and where they need revision today, with examples, and conclude.
Derwent Whittlesey (1936) divided the world into 13 agricultural regions using five criteria: crop and livestock combination, intensity of land use, processing and marketing, degree of mechanisation, and associated buildings.
Relevance today: the broad pattern persists. Intensive subsistence rice farming still dominates the Ganga delta, Java and the Mekong; commercial grain farming continues on the Prairies, the Pampas and the Ukrainian steppe; dairying remains in north-west Europe and New Zealand; plantations persist in Assam, Malaysia and West Africa; nomadic herding survives in the Sahel and Mongolia. The subsistence-commercial distinction is still fundamental.
Map: World sketch comparing selected Whittlesey regions with present-day patterns, marking areas of change such as Punjab and the Brazilian Cerrado.
Changes: the Green Revolution made Punjab commercial; Brazil's Cerrado became a soybean frontier; shifting cultivation has shrunk; contract farming, greenhouses and global value chains blur categories. Whittlesey's scheme thus remains relevant as a framework but needs updating with quantitative and globalisation-sensitive criteria.Q5(c) · Models, Theories and Laws in Human Geography · 10 marks≈ 7 min

Write an explanatory note on geographical systems.
हिंदी में प्रश्न
भौगोलिक तंत्रों पर एक व्याख्यात्मक टिप्पणी लिखिए।
Model answer
Paper and question: Paper I, Q5(c)
Approach: Define a geographical system, explain its components and types (open, closed, morphological, cascading, process-response, control) with examples, and note its significance.
A geographical system is a set of interrelated elements on the earth's surface, linked by flows of energy, matter, people or information, functioning as a whole. The approach entered geography through Chorley (1962) and was developed in Chorley and Kennedy's Physical Geography: A Systems Approach (1971).
Components: elements (for example slopes, rivers, towns), attributes (size, shape), relationships (flows) and boundaries. Most geographical systems are open systems, exchanging energy and matter with their surroundings and tending towards a dynamic equilibrium through negative feedback.
Types (Chorley and Kennedy): morphological systems (relations among form variables, such as slope angle and soil depth); cascading systems (flows passing from one subsystem to another, such as the hydrological cycle); process-response systems (form adjusting to process, such as a river channel to discharge); and control systems (where humans intervene, such as dams and irrigation). Human examples include a drainage basin managed for agriculture, or an urban system of central places.
Diagram: Drainage basin as an open system: inputs (precipitation, energy), stores and flows (interception, infiltration, runoff), outputs (discharge, evaporation) and feedback.
Systems thinking integrates physical and human geography, though it can be mechanistic.Q5(d) · Perspectives in Human Geography · 10 marks≈ 7 min

"वैश्विक संयोजकता की अभिवृद्धि के साथ परम्परागत सांस्कृतिक पहचानों का ह्रास हो रहा है।" व्याख्या कीजिए।
Model answer
Paper and question: Paper I, Q5(d)
Approach: Explain how global connectivity (media, internet, migration, markets) erodes traditional identities, give examples, then show the counter-trends of revival and hybridity.
Cultural identity is a group's sense of belonging based on language, religion, dress, food, festivals and place. Global connectivity through television, the internet, social media, migration and global brands is weakening many traditional markers, a process often called time-space compression (Harvey).
Evidence of loss: youth everywhere adopt similar dress, music and food; English and Hindi replace tribal and dialect languages in India; joint families and village crafts decline; standardised malls and housing create 'placelessness' (Relph); indigenous peoples such as the Jarawa of the Andaman islands face cultural erosion from tourism along the Andaman Trunk Road.
Diagram: Concentric rings of identity (local, regional, national, global), with arrows showing global flows pressing on the inner rings and a counter-arrow of revival.
Yet the loss is partial. Connectivity also enables revival: diasporas sustain festivals abroad, social media popularise folk music and regional cinema, and GI tags protect crafts. Many people hold hybrid or layered identities. The more accurate view is transformation, not simple loss, of traditional identity.Q5(e) · Environmental Geography · 10 marks≈ 7 min
Biodiversity and Sustainable Development
Give an account on sustainable development and its components.
हिंदी में प्रश्न

Model answer
Paper and question: Paper I, Q5(e)
Approach: Give the Brundtland definition and its evolution (Agenda 21, SDGs), explain the economic, social, environmental and institutional components with examples, and note the weak versus strong sustainability debate; draw the three-pillar Venn diagram.
The Brundtland Commission (1987) defined sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It was put into practice through Agenda 21 at the Rio Earth Summit (1992) and the 17 Sustainable Development Goals (2015).
Economic sustainability: growth that raises incomes and jobs without depleting natural capital, through green accounting, resource efficiency and a circular economy.
Social sustainability: equity, poverty reduction, health, education, gender justice and participation, including fairness within and between generations.
Environmental sustainability: using renewable resources within their regeneration rate, releasing wastes within the assimilative capacity of nature and conserving biodiversity, as in India's National Action Plan on Climate Change (2008) and its eight missions.
Diagram: Venn diagram of three overlapping circles (economy, society, environment); overlaps labelled viable, equitable and bearable, with sustainable development at the centre.
A fourth, institutional pillar of good governance and participation is often added. Weak sustainability allows natural capital to be replaced by human-made capital, while strong sustainability holds that critical natural capital must be preserved; the distinction remains debated.

Radical, Behavioural, Humanistic and Welfare Approaches
Discuss the contemporary paradigms of Geography.
हिंदी में प्रश्न
भूगोल के समसामयिक प्रतिमानों (पैराडाइम्स) की विवेचना कीजिए।
Model answer
Paper and question: Paper I, Q6(a)
Approach: Define paradigm (Kuhn), briefly note the older paradigms, then discuss the contemporary ones (systems and GIS-based spatial science, radical-Marxist, behavioural, humanistic, feminist, postmodern and postcolonial, political ecology) with key thinkers, and conclude on pluralism.
A paradigm, in Thomas Kuhn's The Structure of Scientific Revolutions (1962), is a framework of shared assumptions, questions and methods that guides a discipline. Geography moved from determinism, possibilism and regional geography to the quantitative revolution; since about 1970 several paradigms coexist.
Spatial science and systems: the positivist legacy continues through systems analysis (Chorley and Kennedy, 1971), spatial modelling and now GIS, remote sensing and big data. It dominates applied work in planning, disaster mapping and location analysis.
Behavioural geography: perception, cognition and decision-making (Kirk, Wolpert, Golledge, Gould's mental maps) explain how people actually choose locations and respond to hazards.
Radical and Marxist geography: Harvey, Neil Smith and Massey analyse uneven development, urbanisation of capital and spatial justice. Welfare geography (D.M. Smith) measures well-being and inequality.
Humanistic geography: Tuan, Relph, Buttimer and Ley use phenomenology and existentialism to study place, meaning and lived experience.
Newer currents: feminist geography (gendered space, women's mobility); postmodern geography (Soja, Dear) stressing difference and multiple voices; postcolonial geography challenging Eurocentrism; political ecology (Blaikie and Brookfield, 1987) and earth-system science linking society and environment in the Anthropocene; and the 'cultural turn' and non-representational theory.
Diagram: Tree diagram: a trunk of classical geography branching into spatial science, behavioural, radical, humanistic, feminist, postmodern-postcolonial and political-ecology branches, with dates and key names.
Contemporary geography is therefore pluralist: paradigms compete but also combine, for example GIS used in participatory and critical studies of land rights in India. This pluralism is a strength, allowing geography to address climate change, inequality and urbanisation from several angles.Q6(b) · Economic Geography · 15 marks≈ 11 min
World Resources, Energy Crisis and the Limits to Growth
"The intensity of energy crisis varies regionally." Explain.
हिंदी में प्रश्न
"ऊर्जा संकट की उग्रता में प्रादेशिक विषमता होती है।" व्याख्या कीजिए।
Model answer
Paper and question: Paper I, Q6(b)
Approach: Define energy crisis, then explain its regional variation by grouping regions (import-dependent developed, energy-poor developing, exporters, emerging economies, island states) with examples and a world map, and conclude.
An energy crisis is a gap between energy demand and secure, affordable supply. Its intensity varies regionally because resource endowment, import dependence, income, technology and infrastructure differ.
Import-dependent developed regions: Japan, South Korea and much of Europe import most of their oil and gas, so their crisis is one of supply security; Europe's 2022 gas crisis after Russian supplies fell is an example. High incomes and efficiency soften the impact.
Energy-poor developing regions: in sub-Saharan Africa hundreds of millions lack electricity and depend on firewood and charcoal; here the crisis is energy poverty, with effects on health, education and livelihoods.
Emerging economies: India and China face fast-growing demand, dependence on coal and imported oil, air pollution and the need to decarbonise; India imports about 85 per cent of its crude oil.
Exporters: Gulf states, Russia and Norway have abundant supply but face revenue risk from price falls and the global energy transition.
Map: World choropleth of energy import dependence and electricity access, marking Japan, Europe, sub-Saharan Africa, India, China and the Gulf.
Within India, too, the crisis varies: per capita consumption is high in Punjab and Gujarat but low in Bihar and the North-east. Regional solutions are therefore needed.Q6(c) · Population Geography · 15 marks≈ 11 min
Migration: Causes and Consequences
Examine the causes and consequences of forced migration of population in the present context.

Model answer
Paper and question: Paper I, Q6(c)
Approach: Define forced migration and its types, give its present scale (UNHCR), then examine causes and consequences for migrants, origin, host areas and the world, with current examples, and suggest responses.
Forced migration is movement in which an element of coercion prevails, including threats to life and livelihood from conflict, persecution, disasters or development projects. It includes refugees, asylum-seekers, internally displaced persons (IDPs) and victims of trafficking. UNHCR reported about 123 million forcibly displaced people worldwide by the end of 2024.
Causes: (i) armed conflict and civil war: Syria, Ukraine (since 2022), Sudan (since 2023, now the largest displacement crisis), Gaza, Myanmar and the DRC; (ii) persecution of minorities, such as the Rohingya expelled from Myanmar in 2017 to Cox's Bazar in Bangladesh; (iii) state collapse and violence, as in Afghanistan and Venezuela; (iv) climate-related disasters; (v) development projects; (vi) ethnic violence within countries, as in Manipur in 2023.
Consequences: for migrants, loss of life, assets, education and identity, trauma, and protracted camp life; for origins, depopulation and loss of skilled people; for hosts, pressure on land, water, jobs and services, as in Lebanon, Turkey, Uganda and Bangladesh, and political backlash in Europe; at the global level, humanitarian funding gaps and dangerous sea crossings in the Mediterranean.
Map: World map of major forced-migration flows: Syria to Turkey and Europe, Ukraine to Poland and Germany, Sudan to Chad and Egypt, Myanmar to Bangladesh, Afghanistan to Iran and Pakistan, Venezuela to Colombia.
Responses: conflict resolution, the Global Compact on Refugees (2018) for burden-sharing, durable solutions (voluntary return, local integration, resettlement), and protection of IDPs under the Guiding Principles (1998). India, though not party to the 1951 Convention, has hosted Tibetans, Sri Lankan Tamils and others under ad hoc arrangements.

Central Place Theories of Christaller and Losch
Discuss the applicability of Christaller's Central Place Theory.
हिंदी में प्रश्न
क्रिस्टालर के केन्द्र स्थान सिद्धांत की प्रयोज्यता की विवेचना कीजिए।
Model answer
Paper and question: Paper I, Q7(a)
Approach: Summarise Christaller's theory with assumptions and hexagons, then discuss its applicability: empirical tests, applications in planning and retailing (world and India), and the conditions under which it fails, concluding with a balanced view.
Walter Christaller (1933), studying southern Germany, proposed that settlements exist mainly to supply goods and services to their surroundings. On an isotropic plain with evenly spread, rational consumers, each good has a threshold and a range; market areas become hexagons, and central places form a hierarchy arranged by the marketing (k = 3), traffic (k = 4) and administrative (k = 7) principles.
Empirical applicability: Brian Berry and William Garrison (1958) found a clear hierarchy of central places in Snohomish County, Washington; studies in the American Midwest, East Anglia and the Iowa plains showed regular spacing; in India, studies of the Ganga plain, Punjab and the Kaveri delta found hierarchies of villages, market towns and district centres approaching central place patterns.
Planning applications: the reclaimed polders of the Netherlands (Noordoostpolder) and Israel's Lachish region were settled with a planned central place hierarchy; India's hierarchy of health and education facilities, growth centre programme (1988) and rural service centre concepts use its logic; retailers and banks use it for network planning.
Diagram: Christaller's nested hexagons (k = 3) beside a map sketch of a district in the Ganga plain showing villages, market towns and the district town spaced at increasing intervals.
Where it fails: (i) uneven relief and resources distort hexagons, as in hills and coasts; (ii) transport routes create linear patterns; (iii) industrial, mining and port towns are not service centres; (iv) modern mobility, e-commerce and multi-purpose trips break distance decay; (v) historical, political and cultural factors shape settlement; (vi) the fixed k is rigid, as Losch showed.
Christaller's theory is thus most applicable to agricultural plains and to normative planning of service hierarchies, and least to industrial or rugged regions; its value lies in providing a benchmark against which real settlement systems can be compared.Q7(b) · Population Geography · 15 marks≈ 11 min

Model answer
Paper and question: Paper I, Q7(b)
Approach: Identify the demographic similarities between Western Europe and Japan (low fertility, high longevity, ageing, slow or negative growth, late marriage, urban small households) with figures, explain common causes, and note key differences.
Western Europe (Germany, Italy, Spain, France, the UK) and Japan are both in the late stages of the demographic transition, the fourth or the proposed fifth stage, and show striking similarities.
Similarities: (i) below-replacement fertility: Japan's total fertility rate is about 1.2, Italy's and Spain's similar, Germany's about 1.4; (ii) very high life expectancy, over 84 years in Japan and over 82 in Italy and Spain; (iii) rapid ageing: Japan has nearly 30 per cent of its population aged 65 and above, Italy and Germany over 22 per cent; (iv) low or negative natural increase, with Japan's population falling since 2008 and deaths exceeding births in Italy and Germany; (v) late marriage and childbearing, many single-person households, and high urbanisation.
Common causes: high incomes and education, women's participation in work, the high cost of child-rearing and housing, secularisation and individualistic values, and advanced health care.
Diagram: Side-by-side population pyramids of Japan and Italy, both with narrow bases and bulging upper middle ages.
Differences: Western Europe offsets decline through large-scale immigration, while Japan has accepted few immigrants; France and the Nordic states have somewhat higher fertility because of family-friendly policies. Both face similar challenges of pensions, care and labour shortages.Q7(c) · Population Geography · 15 marks≈ 11 min

हिंदी में प्रश्न
जीवन की गुणता को परिभाषित कीजिए तथा पर्याप्त उदाहरणों सहित इसके प्राचलों की व्याख्या कीजिए।
Model answer
Paper and question: Paper I, Q7(c)
Approach: Define quality of life (WHO), list its objective and subjective parameters with indices (PQLI, HDI, Better Life Index, Ease of Living) and examples, and conclude.
The WHO defines quality of life as individuals' perception of their position in life in the context of the culture and value systems in which they live, in relation to their goals, expectations, standards and concerns. It is broader than income and includes both objective conditions and subjective well-being.
Objective parameters: (i) health: life expectancy, infant mortality, nutrition; (ii) education and literacy; (iii) income, employment and poverty; (iv) housing, safe water, sanitation and electricity; (v) environment: air and water quality, green space; (vi) safety and crime; (vii) social and political freedom. Subjective parameters: life satisfaction, happiness, sense of security and belonging.
Measures: Morris D. Morris's Physical Quality of Life Index (1979) combines literacy, infant mortality and life expectancy at age one; UNDP's HDI (1990); the OECD Better Life Index (2011) with eleven dimensions; the World Happiness Report, where Finland has ranked first for several years; and India's Ease of Living Index for cities (2018, 2020), in which Bengaluru ranked first in 2020.
Diagram: Wheel diagram with quality of life at the centre and spokes for health, education, income, housing, environment, safety, freedom and life satisfaction.
Examples: Kerala's high PQLI at moderate income contrasts with richer but less equal states. Quality of life thus depends on distribution and public services as much as on growth.

Heartland and Rimland Theories; Boundaries and Frontiers
"The Heartland Theory is gaining importance once again." Comment.
हिंदी में प्रश्न
"केन्द्र-स्थल (हार्टलैंड) सिद्धांत एक बार पुनः महत्त्वपूर्ण हो रहा है।" समीक्षा कीजिए।
Model answer
Paper and question: Paper I, Q8(a)
Approach: Outline the Heartland theory and its decline in relevance during the late Cold War, then comment on the factors behind its renewed importance (Russia's resurgence, Central Asian energy, China's BRI, SCO, connectivity), with a map, and give a balanced view.
Halford Mackinder's Heartland theory (1904, revised 1919 and 1943) held that the interior of Eurasia, protected from sea power and rich in resources, gave its ruler a base for world domination. During the Cold War the Soviet Union occupied the Heartland, but air power, nuclear weapons and US maritime supremacy seemed to make the theory obsolete, and the Soviet collapse in 1991 appeared to confirm this.
Why it is regaining importance: (i) Russia's resurgence: its actions in Georgia (2008), Crimea (2014) and the full-scale invasion of Ukraine (2022) are a contest for East Europe, Mackinder's gateway to the Heartland; (ii) Central Asian energy and minerals: oil and gas from Kazakhstan and Turkmenistan, and uranium, attract China, Russia, Europe and India, reviving a 'new Great Game'; (iii) China's Belt and Road Initiative (2013) and the China-Europe railway turn the Heartland into a transcontinental corridor, reducing dependence on vulnerable sea lanes such as the Strait of Malacca; (iv) the Shanghai Cooperation Organisation and the Russia-China strategic partnership resemble a Heartland bloc; (v) the Arctic, warming and opening, adds new northern routes and resources; (vi) India's Chabahar port, INSTC and membership of the SCO aim to secure Heartland access.
Map: Eurasia showing the Heartland, the China-Europe rail and pipeline corridors, Chabahar-INSTC, Ukraine and the Northern Sea Route.
Balanced view: technology, maritime trade, which still carries most world commerce, and economic power mean that no single power can 'command the world' from the Heartland; the region is also landlocked, sparsely populated and politically fragmented. Thus the Heartland is gaining importance as an arena of competition and connectivity rather than as a guaranteed seat of world power.
For India, engaging Central Asia while balancing Russia, China and the West is the practical lesson of the Heartland's revival.Q8(b) · Regional Planning · 15 marks≈ 11 min

Examine the role of small towns in the regional development process.
हिंदी में प्रश्न
प्रादेशिक विकास प्रक्रम में छोटे नगरों की भूमिका का परीक्षण कीजिए।
Model answer
Paper and question: Paper I, Q8(b)
Approach: Define small towns and their place in the settlement hierarchy, examine their roles (service, market, processing, rural-urban linkage, absorbing migration), with Indian schemes and examples, and note constraints.
Small towns, usually with populations below about 50,000 (Census classes IV to VI), form the intermediate tier between villages and large cities in the central place hierarchy. They are the points where urban services first reach rural people.
Roles: (i) service centres providing schools, colleges, hospitals, banks and government offices to surrounding villages, as in Christaller's lower-order central places; (ii) market centres: mandis and periodic markets that link farmers to wider markets, essential for commercialisation of agriculture; (iii) agro-processing and small industry: rice mills, cotton ginning, dairy units, cold storage and handlooms, creating non-farm jobs; (iv) rural-urban linkages, channelling inputs, credit, information and innovations downward and produce upward, so that development diffuses through the hierarchy; (v) absorbing rural migrants close to home, reducing pressure on metropolises; (vi) growth foci in the strategies of R.P. Misra and the 'integrated area development' approach.
Indian policy recognised this through the Integrated Development of Small and Medium Towns scheme (1979), the growth centre programme (1988), the PURA concept, and the Shyama Prasad Mukherji Rurban Mission (2016), which develops rurban clusters.
Diagram: Settlement hierarchy pyramid: villages at the base, small towns as service and market centres in the middle, and cities at the top, with two-way flows of goods, services and people.
Constraints: weak municipal finances, poor infrastructure, stagnant economies and loss of population to big cities. Strengthening small towns is therefore key to balanced regional development.Q8(c) · Population Geography · 15 marks≈ 11 min
Population Problems, Policies, Well-being and Social Capital
Explain the concept of social capital in relation to India.
हिंदी में प्रश्न
भारत के सम्बन्ध में सामाजिक पूँजी की संकल्पना की व्याख्या कीजिए।
Model answer
Paper and question: Paper I, Q8(c)
Approach: Define social capital (Bourdieu, Coleman, Putnam) and its forms, then explain its positive and negative manifestations in India with examples, and conclude on how to build it.
Social capital refers to the networks, norms and trust that enable people to act together for mutual benefit. Pierre Bourdieu saw it as resources gained through membership of groups, James Coleman as a resource that facilitates action, and Robert Putnam (Making Democracy Work, 1993; Bowling Alone, 2000) as civic engagement that makes institutions work. Putnam distinguished bonding (within groups), bridging (across groups) and linking (with institutions) social capital.
Positive examples in India: women's self-help groups under DAY-NRLM, now covering around ten crore women, and Kerala's Kudumbashree (1998) build savings, credit and collective enterprise; dairy cooperatives such as Amul in Gujarat; Joint Forest Management and water user associations; trading networks of Marwari, Gujarati and Chettiar communities; and diaspora networks that support migration and investment.
Negative side: strong bonding capital based on caste, religion or kin can exclude outsiders, reinforce hierarchy, and foster nepotism and identity politics; khap panchayats are an extreme case.
Diagram: Three-ring diagram: bonding (family, caste), bridging (SHG federations, cooperatives, civic groups) and linking (panchayats, banks, government), with Indian examples in each ring.
Building bridging and linking social capital through panchayati raj, cooperatives, SHG-bank linkage and inclusive civic institutions is key to inclusive development in India.

(i) Thumba: Fishing village near Thiruvananthapuram, Kerala (about 8.5°N, 76.9°E), close to the geomagnetic equator. Site of the Thumba Equatorial Rocket Launching Station (first launch 1963), cradle of India's space programme, now part of the Vikram Sarabhai Space Centre.
(ii) Nayachar Island: Silt island in the Hooghly estuary off Haldia, Purba Medinipur district, West Bengal (about 22.0°N, 88.1°E). Formed by river deposition; once proposed for a chemical hub (2006–07), it is used for aquaculture and is debated for ecological fragility and cyclone exposure.
(iii) Doddabetta: Highest peak of the Nilgiri hills at about 2,637 m, near Ooty, Nilgiris district, Tamil Nadu (about 11.4°N, 76.7°E). Part of the Nilgiri Biosphere Reserve (India's first, 1986) with shola–grassland mosaics; tea-growing area; a telescope house for tourists.
(iv) Devasthal: Mountain-top site at about 2,450 m in Nainital district, Uttarakhand (about 29.4°N, 79.7°E). ARIES runs here India's largest optical telescope, the 3.6 m Devasthal Optical Telescope (2016, with Belgium), and the International Liquid Mirror Telescope (2022); dark, clear skies.
(v) Pangong Lake: Endorheic saline lake at about 4,350 m in eastern Ladakh (about 33.7°N, 78.7°E), about 134 km long, of which roughly one-third lies in India and the rest in Tibet. Its ‘fingers’ on the north bank were a flashpoint in the 2020 standoff; brackish water freezes in winter.
(vi) Hampi: Ruins of Vijayanagara, capital of the Vijayanagara empire (14th–16th century), on the Tungabhadra in Vijayanagara district, Karnataka (about 15.3°N, 76.5°E). UNESCO World Heritage Site (1986); Virupaksha and Vittala temples amid granite boulder terrain.
(vii) Havelock Island: Renamed Swaraj Dweep (2018), in Ritchie's Archipelago, South Andaman district (about 12.0°N, 93.0°E). Known for Radhanagar beach, coral reefs and scuba diving; tourism hub of the Andamans, facing coral bleaching and carrying-capacity concerns.
(viii) Luni River: Rises in the Naga hills near Pushkar, Ajmer district, Rajasthan, and flows south-west about 495 km to the Rann of Kutch. The only significant river of the Thar's inland drainage; turns saline after Balotra; seasonal floods; supports wells and agriculture in Barmer and Jalore.

हिंदी में प्रश्न
भारत में 2017 में मानसूनी वर्षा के वितरण के असामान्य प्रतिरूप का तर्कयुक्त विवरण दीजिए।
Model answer
Paper and question: Paper II, Q1(b)
Approach: Give the national figure for 2017, describe the unusual regional and temporal pattern with examples, then explain the reasons. Draw a map of 2017 subdivision-wise rainfall departures.
The 2017 south-west monsoon gave 95% of the long period average for India as a whole (IMD), just inside the normal band, against a forecast of 98%. The national total hid a highly uneven distribution in space and time.
Unusual pattern: intense spells caused floods in Gujarat (Banaskantha, July), Assam and north Bihar (August) and Mumbai (29 August). At the same time parts of central and north-western India received deficient rain, and September brought only about 76% of normal rain for the country. Several subdivisions thus suffered both floods and dry spells within one season.
Reasons: (i) IMD attributed the late-season deficit to intraseasonal variations linked to strong typhoon activity in the north-west Pacific and to fewer monsoon low-pressure systems; (ii) a few slow-moving depressions and offshore troughs dumped very heavy rain locally; (iii) ENSO was neutral with no strong Indian Ocean Dipole support; (iv) a warmer atmosphere tends to concentrate rain into short, extreme bursts.
Map: Map of India's meteorological subdivisions shaded by 2017 rainfall departure, with flood events marked in Gujarat, Assam, Bihar and Mumbai.
2017 showed that a 'normal' national total can conceal regional distress, so district-level planning matters.Q1(c) · Political Aspects · 10 marks≈ 7 min

Paper and question: Paper II, Q1(c)
Approach: Explain the inter-state issues of the SYL canal: its purpose, the 1981 agreement, Punjab's objections, Haryana's claim, legal history and present status; a sketch map of the canal alignment.
The Sutlej–Yamuna Link (SYL) canal, about 214 km long (122 km in Punjab, 92 km in Haryana), was planned to carry Haryana's share of Ravi–Beas water from the Sutlej near Nangal to the Yamuna basin after Punjab's reorganisation (1966).
Allocation issue: the 1981 agreement gave Haryana 3.5 MAF; Punjab argues the 1955 estimate of available water is outdated, its own groundwater is overdrawn and, as the only riparian state, it has no water to spare.
Political issue: the canal became linked with Punjab militancy; construction stopped in 1990, and the Punjab Termination of Agreements Act, 2004 cancelled water pacts.
Legal issue: the Supreme Court ordered completion (2002, 2004) and in 2016 held the 2004 Act invalid, yet Punjab de-notified the canal land in 2016. Haryana has completed its portion and demands enforcement.
Map: Sketch of Punjab and Haryana showing the Sutlej, Nangal, Ropar, the SYL alignment to the Western Yamuna Canal near Karnal, and the Bhakra dam.

Approach: Explain the role and problems of small towns (infrastructure, economy, planning, finance), then their prospects (rural-urban linkage, agro-processing, decongesting metros) with examples and schemes, and conclude. A diagram of the urban hierarchy helps.
Small towns, generally those below 50,000 people (Census size Classes III–VI) and including the 3,894 census towns of 2011, form the link between villages and large cities in India's urban hierarchy.
Problems: (i) poor water supply, sewerage and roads; many census towns are still governed as villages by panchayats; (ii) weak economic base dependent on trade and agriculture, causing out-migration of youth to metros; (iii) absence of master plans and town planners (NITI Aayog, 2021); (iv) meagre municipal finance; (v) central schemes such as JNNURM favoured big cities, while the earlier Integrated Development of Small and Medium Towns (1979–80) had limited funds.
Prospects: (i) agro-processing and market centres (Rajkot, Erode-type mandis) under food processing schemes; (ii) growth centres that diffuse development to rural hinterlands; (iii) cluster industries (Moradabad brassware, Panipat textiles); (iv) decongesting metros as digital connectivity spreads; (v) coverage under AMRUT 2.0 for all statutory towns and the Rurban Mission.
Diagram: Urban hierarchy pyramid: metros at top, Class I cities, medium towns, small towns and census towns, and villages at the base, with arrows of goods and services.
Strengthening small towns can balance India's urbanisation and reduce pressure on metros.

Approach: Establish the dimensions of the freshwater crisis with data (quantity, quality, distribution, governance), then present a structured blueprint for sustainable management (supply, demand, quality, institutions). Draw a map of water-stressed basins and a blueprint diagram.
India has about 18% of the world's people but only about 4% of its freshwater. Per capita availability has fallen from about 1,545 m³ in 2011 to about 1,486 m³ in 2021 and is projected at about 1,367 m³ by 2031 (Central Water Commission), approaching water scarcity.
Dimensions of the crisis: (i) uneven distribution in time and space, since most rain falls in four months and the Brahmaputra and Ganga carry most of the surface flow while western and southern basins (Sabarmati, Pennar, Kaveri) are deficit; (ii) groundwater depletion, with 10.8% of units over-exploited (CGWB, 2025); (iii) pollution of rivers such as the Yamuna and of aquifers with arsenic, fluoride and nitrate; (iv) inefficiency, since agriculture uses roughly 80% of water at low efficiency; (v) conflicts and governance gaps, including interstate disputes and fragmented institutions.
Blueprint (1) Supply: rainwater harvesting and recharge (Catch the Rain, Amrit Sarovar); revival of traditional tanks and wetlands; selective, well-appraised storage and transfers (Ken–Betwa link); desalination for coastal cities.
(2) Demand: micro-irrigation under PMKSY's 'Per Drop More Crop' (2015); crop diversification away from paddy and sugarcane in stressed areas; rational power and water pricing; industrial recycling and zero liquid discharge.
(3) Quality: sewage treatment and reuse of treated wastewater (Namami Gange, AMRUT 2.0); regular quality monitoring.
(4) Institutions: basin-level planning, participatory groundwater management (Atal Bhujal Yojana, 2019), aquifer mapping, a revised National Water Policy, and universal tap supply under the Jal Jeevan Mission (2019) backed by source sustainability.
Map: Map of India showing surplus (Brahmaputra, Mahanadi) and deficit (Sabarmati, Pennar, Kaveri) basins with groundwater-stressed areas shaded.
Such an integrated, demand-led and community-based approach can turn India's water crisis into water security.Q2(b) · Contemporary Issues · 15 marks≈ 11 min

Model answer
Paper and question: Paper II, Q2(b)
Approach: Identify the Naxal-affected belt with current MHA data and a map, then discuss the socio-economic problems that both feed and result from the insurgency, ending with the policy response.
Naxalism, or Left-wing extremism (LWE), began with the Naxalbari uprising (1967, Darjeeling district). The affected ‘Red Corridor’ has shrunk sharply: MHA reported LWE-affected districts falling from 126 in 2018 to 18 in April 2025 and 11 in October 2025, with only three ‘most affected’ districts, Bijapur, Sukma and Narayanpur in Chhattisgarh.
Affected areas: the Dandakaranya forests of south Chhattisgarh (Bastar), Gadchiroli (Maharashtra) and Malkangiri (Odisha); the Andhra–Odisha border; the Chotanagpur plateau of Jharkhand, including the Saranda forest of West Singhbhum; and earlier pockets in Bihar (Gaya, Aurangabad) and Jangalmahal in West Bengal.
Socio-economic problems: the belt is mainly tribal, forested and mineral-rich; land alienation and displacement by mines and dams without fair rehabilitation; denial of forest rights before the Forest Rights Act (2006) and weak use of PESA (1996); exploitation by traders in tendu leaf and minor forest produce; high poverty; and few roads, schools, hospitals or banks.
Problems caused by the conflict: violence against civilians and security forces, destruction of schools and roads, a halt to development projects, and tribal people caught between both sides.
Map: Map of India shading the LWE belt from south Chhattisgarh and Gadchiroli through Malkangiri to West Singhbhum, marking Bijapur, Sukma, Narayanpur and Naxalbari.
Response: the National Policy and Action Plan (2015) and SAMADHAN strategy (2017) combine security with roads, mobile towers, Eklavya schools and banking, and the government set 31 March 2026 as its target to end LWE. Lasting peace needs land rights, PESA and tribal-centred development.Q2(c) · Transport, Communication and Trade · 15 marks≈ 11 min

Critically examine the feasibility of development of a comprehensive network of airways in India.
हिंदी में प्रश्न
भारत में वायुमार्गों के एक व्यापक नेटवर्क का विकास करने की साध्यता का समालोचनात्मक परीक्षण कीजिए।
Model answer
Paper and question: Paper II, Q2(c)
Approach: Assess the case for a comprehensive airway network (geography, demand, regional connectivity, UDAN) against the constraints (costs, airport capacity, terrain, viability, environment), concluding critically on feasibility. Draw a map of airports and UDAN routes.
Air transport is fast, needs no continuous track and can reach remote, rugged and island regions, which makes a comprehensive airway network attractive for a large, diverse country like India.
Factors favouring feasibility: (i) geography: the Himalaya, the north-east, Ladakh and the island territories are poorly served by road and rail, so air links are often the only fast option; (ii) demand: India is now the world's third-largest domestic aviation market, with a growing middle class; (iii) policy: the Regional Connectivity Scheme UDAN (2016) subsidises flights to unserved airports, heliports and water aerodromes, and the number of operational airports has roughly doubled since 2014; (iv) economic benefits: tourism, trade in perishables and high-value goods, and the integration of remote regions; (v) strategic needs: border airstrips and advanced landing grounds.
Constraints: (i) high costs of aviation fuel, aircraft and airports make many regional routes commercially unviable, and several UDAN routes have stopped after their subsidy period ended; (ii) congestion at metro airports and land acquisition for new airports; (iii) difficult terrain and weather in the Himalaya and the north-east; (iv) airline financial failures (Kingfisher, Jet Airways, Go First) and market concentration; (v) environmental concerns, including emissions and noise.
Map: Map of India marking major airports, new greenfield airports and UDAN routes linking the north-east, the Himalaya and the islands.
A comprehensive network is feasible only in a hub-and-spoke form, with continued viability support for remote regions and integration with rail and road.

"An effective three-tier Panchayat Raj System will strengthen the bottom-up approach to multilevel planning in India." Explain.
हिंदी में प्रश्न
"एक प्रभावी त्रिस्तरीय पंचायत राज तंत्र भारत में बहुस्तरीय आयोजना के ऊर्ध्वोन्मुखी उपागम को बल प्रदान करेगा।" व्याख्या कीजिए।
Model answer
Paper and question: Paper II, Q3(a)
Approach: Explain the bottom-up approach and multilevel planning, show how each Panchayat tier contributes and why effectiveness (three Fs, DPCs, participation) is the condition, with examples. Draw the three-tier diagram.
In a bottom-up approach, plans begin with the needs identified by people at the lowest level and are aggregated upward, unlike the top-down sectoral plans of India's early Five Year Plans. Multilevel planning nests these plans from village to block, district, state and nation.
Role of each tier: the Gram Panchayat and Gram Sabha identify needs and prepare the GPDP for drinking water, roads, sanitation and livelihoods; the Panchayat Samiti (block) plans for works beyond one village, such as minor irrigation and secondary roads, and gives technical support; the Zila Parishad integrates block plans with district sectors like health and agriculture, and the District Planning Committee (Article 243ZD) consolidates rural and urban plans into the district plan that feeds the state plan.
Why 'effective' matters: the Dantwala (1978) and Hanumantha Rao (1984) working groups had recommended block and district planning, but without funds and staff these remained recommendations. The 73rd Amendment (1992) gave tiers constitutional status, and the Fourteenth and Fifteenth Finance Commission grants gave them money; where states also transferred functions and staff, as in Kerala and Karnataka, bottom-up planning became real.
Examples: Kerala's People's Plan Campaign (1996) produced plans from ward sabhas upward; Ralegan Siddhi's watershed plan grew from village needs into a district model; the Aspirational Blocks Programme (2023) now focuses on the block as a planning unit.
Diagram: three-tier pyramid with the Gram Sabha at the base, Gram Panchayat, Panchayat Samiti and Zila Parishad above, feeding the District Planning Committee and state plan; arrows show plans moving up and funds moving down.
Constraints: uneven devolution, weak DPCs, scheme-tied funds and elite capture can make the system top-down in practice.
The statement holds true, provided the three tiers are genuinely empowered; then local plans become the building blocks of state and national plans.Q3(b) · Cultural Setting and Population of India · 15 marks≈ 11 min

Model answer
Paper and question: Paper II, Q3(b)
Approach: Describe the distribution of language families and major languages with Census 2011 data, explain why diversity is both an asset and a challenge, and list the constitutional and policy steps. Draw a language-family map.
India has four major language families: Indo-Aryan (about 78% of speakers), Dravidian (about 20%), Austro-Asiatic and Tibeto-Burman (about 1% each). Census 2011 recorded 22 scheduled languages; Hindi is spoken by 43.6% of the population, followed by Bengali (8.0%), Marathi (6.9%), Telugu (6.7%) and Tamil (5.7%).
Distribution: Indo-Aryan languages occupy the northern plains, Gujarat, Maharashtra and the east; Dravidian languages the peninsula south of the Krishna–Godavari; Austro-Asiatic (Santhali, Mundari, Ho, Khasi) the Chota Nagpur plateau and Meghalaya; Tibeto-Burman the Himalaya and the North East.
Asset: rich literature and cultural heritage, a multilingual workforce for services and tourism, and linguistic states that made administration closer to the people.
Challenge: language agitations (anti-Hindi movement in Tamil Nadu, 1965), border disputes such as Belagavi, demands for new states and scheduling of more languages, neglect of tribal tongues, and difficulties in national communication.
Steps taken: States Reorganisation Act, 1956 on the Fazl Ali Commission’s advice; the Eighth Schedule (now 22 languages); Article 350A (primary education in the mother tongue) and Article 350B (Commissioner for Linguistic Minorities); the three-language formula (1968, retained flexibly in NEP 2020); and classical-language status, extended to 11 languages by 2024.
Map: Outline map of India shading the Indo-Aryan, Dravidian, Austro-Asiatic and Tibeto-Burman zones, with major languages labelled in each.

How may tourism in hilly areas of India be developed as an important source of economy?
हिंदी में प्रश्न
भारत के पहाड़ी क्षेत्रों में पर्यटन को अर्थव्यवस्था के एक महत्त्वपूर्ण स्रोत के रूप में किस प्रकार विकसित किया जा सकता है?
Model answer
Paper and question: Paper II, Q3(c)
Approach: Show the tourism assets of India's hilly areas, then explain how tourism can become an important economic source (forms of tourism, linkages, jobs), with strategies and safeguards. Draw a map of hill tourism destinations.
India's hilly areas, including the Himalaya, the north-eastern hills, the Western Ghats and the Nilgiris, have scenic landscapes, a cool climate, snow, forests, wildlife, pilgrimage sites and distinct cultures, but limited farmland and industry. Tourism is therefore one of their best economic options.
Forms of tourism to develop: (i) leisure and hill-station tourism (Shimla, Darjeeling, Ooty, Munnar); (ii) pilgrimage tourism (Char Dham, Vaishno Devi, Amarnath, Hemkund Sahib); (iii) adventure tourism: trekking, mountaineering, river rafting at Rishikesh, paragliding at Bir Billing and skiing at Gulmarg and Auli; (iv) ecotourism and wildlife tourism (Corbett, Kaziranga, the Valley of Flowers); (v) cultural and rural tourism through homestays, festivals such as Hornbill (Nagaland) and crafts; (vi) wellness tourism: yoga and Ayurveda.
How it supports the economy: direct jobs in hotels, transport and guiding; demand for local produce (apples, tea, handicrafts); income for women and youth, reducing outmigration from the hills of Uttarakhand; and revenue for local bodies.
Strategies: better all-weather roads, ropeways and air links (UDAN); homestay schemes; skill training for guides; branding of lesser-known destinations to spread visitors; and year-round circuits.
Safeguards: carrying-capacity limits, waste management, building codes on unstable slopes and protection of forests and water sources.
Map: Map of India marking hill tourism destinations: Gulmarg, Shimla, Manali, Rishikesh, Auli, Darjeeling, Gangtok, Shillong, Munnar and Ooty.
Planned, community-based and green hill tourism can make tourism a sustainable economic base for India's mountains.

Urban Development, Morphology and Functional Classification of Indian Cities
Mention various methods of functional classification of towns in India and explain the method applied by Asok Mitra.
हिंदी में प्रश्न
भारत में नगरों के प्रकार्यात्मक वर्गीकरण की विभिन्न विधियों का उल्लेख कीजिए तथा अशोक मित्रा द्वारा अनुप्रयुक्त विधि को स्पष्ट कीजिए।
Model answer
Paper and question: Paper II, Q4(a)
Approach: List the main methods of functional classification used for Indian towns (qualitative, statistical, multivariate) with their authors, then explain Asok Mitra's method in detail with its classes and an evaluation. A table-like flow diagram helps.
Functional classification groups towns by the dominant economic activity of their workforce, revealing their role in the regional economy and guiding planning.
Methods: (i) Descriptive or qualitative: towns named by their obvious function (administrative, religious, port, hill station), as in early studies by geographers such as Aurousseau (1921). (ii) Fixed-threshold method: Chauncy Harris (1943) set employment cut-offs for manufacturing, retail, wholesale and other classes. (iii) Statistical method: Howard Nelson (1955) used the mean plus one, two or three standard deviations of each activity to grade specialisation. (iv) Indian adaptations: Asok Mitra (1961 Census) and Qazi Ahmad (1965), who used several socio-economic variables; later scholars used multivariate methods such as factor analysis on census data.
Asok Mitra's method: he took the 1961 Census distribution of workers in nine industrial categories and regrouped them into three sectors: manufacturing, trade and transport, and services. For each town the percentage of workers in each sector was calculated; the leading sector gave the main class, and where a second sector was also strong the town was given a mixed class.
Classes: manufacturing towns (Jamshedpur, Bhilai, Kanpur), trade-and-transport towns (Mughalsarai, Kandla, Siliguri), service towns (Shimla, Dehradun, Mhow), and mixed categories such as manufacturing-cum-trade or service-cum-manufacturing.
Diagram: Flow chart from nine census worker categories to three sectors, sector shares per town, and main and mixed classes, with one example town in each box.
Evaluation: the method is simple, uses uniform census data and suits Indian towns where household industry and services dominate, so it shaped all later Indian classifications. Its limits are reliance on a single variable, the neglect of informal and seasonal workers, arbitrary cut-offs, and a static view that cannot capture the rapid post-1991 shift to services.Q4(b) · Contemporary Issues · 15 marks≈ 11 min

Model answer
Paper and question: Paper II, Q4(b)
Approach: Give the scale with NCRB data, explain general causes and then the specific causes in Maharashtra, Andhra Pradesh and Punjab, and suggest remedies; map the distress districts.
Farmers' suicides are the starkest sign of agrarian distress. NCRB's Accidental Deaths and Suicides in India 2023 recorded 10,786 suicides in the farm sector (4,690 farmers and 6,096 agricultural labourers), with Maharashtra reporting the largest share, followed by Karnataka.
General causes: small holdings (86.1% small and marginal, Agricultural Census 2015–16), rainfed farming exposed to drought, rising input costs, volatile prices, debt to private moneylenders, crop failure from pests, and weak insurance and social support.
Maharashtra: in Vidarbha and Marathwada, rainfed cotton and soybean on black soils face erratic rain, the pink bollworm's resistance to Bt cotton and price crashes, while costly inputs push farmers into debt.
Andhra Pradesh: in Anantapur and other Rayalaseema districts, groundnut and cotton fail in drought and borewells run dry; tenant farmers, who cultivate much of the coastal delta land, cannot get bank credit or crop insurance because they lack title.
Punjab: in the Malwa districts of Bathinda, Mansa and Sangrur, Green Revolution yields have plateaued, costs of machinery and inputs are high, groundwater is falling, and debts to commission agents (arhtiyas) mount; the whitefly attack on cotton (2015) triggered a wave of suicides.
Map: Map of India marking Vidarbha and Marathwada (Maharashtra), Anantapur (Andhra Pradesh) and Bathinda, Mansa and Sangrur (Punjab) as distress hotspots, with cotton and rainfed belts shaded.
Remedies: income support (PM-KISAN, 2019; Andhra's Rythu Bharosa, 2019), better PMFBY crop insurance (2016), institutional credit for tenants through cultivator rights laws, crop diversification and water-saving irrigation, MSP with assured procurement, the Swaminathan Commission's (2004–06) proposals, and rural mental-health counselling.Q4(c) · Agriculture in India · 15 marks≈ 11 min

Paper and question: Paper II, Q4(c)
Approach: Explain why land reform is key to modern agriculture, then describe the post-Independence measures (intermediary abolition, tenancy reform, ceilings, consolidation, Bhoodan, record modernisation, leasing) with regional outcomes. Draw a map of reform success regions.
Land reform aims to give the tiller secure rights to land so that he has the incentive and ability to invest in modern inputs. At Independence, zamindari, insecure tenancy and fragmented holdings were the main barriers to modern agriculture.
Measures: (i) abolition of intermediaries (zamindari, jagirdari) in the early 1950s, which brought tenants into direct contact with the state and was the most successful reform; (ii) tenancy reforms regulating rent and giving security, notably Operation Barga in West Bengal (1978) and reforms in Kerala; (iii) land ceilings to redistribute surplus land, which had limited success because of benami transfers and loopholes; (iv) consolidation of holdings, highly successful in Punjab, Haryana and western Uttar Pradesh, which laid the base for the Green Revolution; (v) Bhoodan and Gramdan (Vinoba Bhave, 1951), a voluntary land-gift movement.
Recent measures: computerisation of land records (DILRMP), drone-based property cards under SVAMITVA (2020), the Model Agricultural Land Leasing Act (2016) to legalise tenancy, and unique land parcel identification numbers.
Map: Map of India marking consolidation success in Punjab and Haryana, tenancy reform in West Bengal and Kerala, and weak reform areas in Bihar and eastern Uttar Pradesh.
Modernising agriculture today requires clear titles, legal leasing and land markets that also protect small farmers.

Model answer
Paper and question: Paper II, Q5(a)
Approach: Explain what the transport subsidy scheme was, which areas it covered and how it worked, then assess its role in reducing regional imbalance and its weaknesses. Draw a map of covered areas.
The Transport Subsidy Scheme (1971), often called the hill transport subsidy, was a central scheme to promote industry in hilly, remote and inaccessible areas.
Coverage and working: it applied to the northeastern states including Sikkim, Jammu and Kashmir, Himachal Pradesh, the hill districts of Uttar Pradesh (now Uttarakhand), Darjeeling, and the Andaman and Nicobar and Lakshadweep islands. Eligible manufacturing units were reimbursed a share, between 50 and 90 percent over time, of the cost of moving raw materials and finished goods between a designated rail-head, such as Siliguri for the Northeast, and the unit.
Role in reducing imbalance: it offset the locational disadvantage of distance and terrain, encouraged small and medium units in Assam, Meghalaya and Himachal.
Weaknesses: CAG audits reported misuse through inflated claims, benefits went to a few large units, and local linkages were weak; it was replaced by the Freight Subsidy Scheme (2013), itself discontinued in 2016.
Map: India outline shading the Northeast, Sikkim, Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Darjeeling and the island territories, with Siliguri marked.

Paper and question: Paper II, Q5(b)
Approach: Bring out the implications of Doklam: what happened in 2017 and why the plateau matters (Siliguri corridor, Bhutan), then the implications for India–China relations; sketch of the trijunction.
Doklam is a plateau claimed by both Bhutan and China near the India–Bhutan–China trijunction, east of Sikkim's Nathu La and overlooking the Chumbi valley. In June 2017 Indian troops stopped a Chinese road crew building towards the Jampheri ridge; the standoff lasted about 73 days and ended with mutual disengagement on 28 August 2017.
Strategic geography: a Chinese road to the Jampheri ridge would overlook the Siliguri corridor, about 20–22 km wide, which links the Northeast to the rest of India.
Implications: India acted on behalf of Bhutan, affirming its security role under the 2007 treaty; China later built villages and roads on the Doklam plateau's eastern side; trust declined, foreshadowing Galwan (2020); the informal Wuhan summit (2018) followed as damage control; and Bhutan–China boundary talks became a concern for India.

Approach: Explain what IRNSS (NavIC) is and its significance for strategic, economic and civilian purposes. Draw a coverage diagram.
The Indian Regional Navigation Satellite System (IRNSS), or NavIC, is India's independent satellite navigation system, developed by ISRO with satellites in geostationary and geosynchronous orbits covering India and about 1,500 km around it.
Significance: (i) strategic autonomy: after India was denied GPS data during the Kargil conflict (1999), NavIC gives the armed forces an assured, encrypted restricted service for navigation and precision-guided weapons; (ii) civilian uses: a standard positioning service for vehicle tracking, fleet management, mapping, surveying and timing for power grids, telecommunications and banking; (iii) disaster management and fisheries: alerts to fishermen at sea and support during cyclones; (iv) economic and technological gains: a domestic industry for receivers and chips; (v) regional diplomacy: services can be offered to neighbouring countries.
Diagram: Diagram of NavIC satellites with the coverage area over India and the surrounding region up to about 1,500 km.

Paper and question: Paper II, Q5(d)
Approach: Explain what mini steel plants are and how their technology frees them from the coal–iron belt, then show how they decentralise the industry with examples, noting limits. Draw a map of integrated plants versus mini-steel clusters.
Mini steel plants are small units that make steel in electric arc or induction furnaces from scrap and sponge iron (direct reduced iron) instead of iron ore and coking coal in blast furnaces.
Why they decentralise the industry: (i) they do not need large coking coal and iron ore sources, so they can locate near markets, ports or scrap sources rather than only in the Chotanagpur–Odisha belt; (ii) their small capital needs and short gestation suit regional entrepreneurs; (iii) they serve local demand for bars, rods and castings, cutting transport costs; (iv) they use electricity, which can be transmitted to any region.
Examples: Mandi Gobindgarh and Ludhiana (Punjab), Jalna (Maharashtra), Raipur and Raigarh (Chhattisgarh), Durgapur, and clusters in Gujarat and Tamil Nadu. India is the world's largest producer of sponge iron, and the secondary steel sector produces a large share of national output.
Limits: high power costs, dependence on imported scrap, and pollution from coal-based sponge iron units.
Map: Map of India contrasting integrated plants in the eastern mineral belt with mini-steel clusters in Punjab, Maharashtra, Chhattisgarh, Gujarat and Tamil Nadu.
Mini plants thus spread steel-making beyond the mineral belt.Q5(e) · Contemporary Issues · 10 marks≈ 7 min

Model answer
Paper and question: Paper II, Q5(e)
Approach: Explain how the destination-based design of GST shifts revenue between producing and consuming states and how it affects developed and backward states differently, and why; a simple flow diagram helps.
The Goods and Services Tax, introduced on 1 July 2017, is a destination-based consumption tax: revenue accrues to the state where goods are consumed, not where they are made, which affects states differently.
Developed manufacturing states: Maharashtra, Gujarat, Tamil Nadu and Karnataka lost the origin-based Central Sales Tax and feared losses, so the GST (Compensation to States) Act, 2017 guaranteed 14% annual revenue growth for five years, until June 2022. Their large markets and formal firms adapted quickly.
Backward consuming states: Uttar Pradesh, Bihar and others gain in principle as consumers, but their low incomes limit the tax base; they also lost the power to offer tax holidays to attract industry, and their many informal small firms face compliance costs.
Common gain: removal of check-posts created a single market and cut freight time, helping landlocked states.
Diagram: Flow diagram showing goods made in Gujarat and sold in Bihar, with tax shifting from the producing to the consuming state.
Overall, GST has made revenue follow consumption, so backward states gain only as their incomes rise.

Model answer
Paper and question: Paper II, Q6(a)
Approach: State the claimed irrigation and navigation benefits of ILR with NWDA figures, then comment on feasibility under physical, economic and ecological heads, and give a balanced conclusion; draw the ILR map with national waterways.
The Interlinking of Rivers programme of the National Water Development Agency (set up 1982) plans 30 links under the National Perspective Plan (1980). NWDA projects about 35 million ha of additional irrigation (25 million ha from surface water and 10 million ha from groundwater) and about 34,000 MW of hydropower, besides flood moderation and navigation.
Assured irrigation: transfers from the Brahmaputra, eastern Ganga tributaries, Mahanadi and Godavari could serve drought-prone Bundelkhand, Rayalaseema, Tamil Nadu and western Rajasthan; Ken–Betwa alone is planned to irrigate about 10.6 lakh ha a year.
All-weather navigation: link canals with assured flow could join the 111 national waterways declared in 2016, such as NW-1 on the Ganga, giving cheap bulk transport.
Physical feasibility: the Himalayan links need huge storage dams in seismic zones and in Nepal and Bhutan; peninsular canals must cross the Vindhyan and Eastern Ghats divides, needing high lifts; and monsoon floods and lean flows often occur in all basins at the same time, questioning the very idea of ‘surplus’. Canals with varying gradients and lifts cannot easily carry ships all year, so continuous navigation is doubtful.
Economic feasibility: the 2002 task force put the cost at about ₹5.6 lakh crore at then prices; pumping costs, evaporation losses, long gestation and resettlement raise it further, while cheaper options such as drip irrigation and watershed development give quicker returns.
Ecological feasibility: submergence of forests (Panna Tiger Reserve under Ken–Betwa), loss of sediment to deltas such as the Sundarbans and Krishna–Godavari, salinity intrusion, species mixing and waterlogging in new commands.
Map: Map of India showing the 14 Himalayan and 16 peninsular links as arrows, NW-1 (Ganga), NW-2 (Brahmaputra) and NW-3 (West Coast Canal), and drought-prone target regions shaded.
ILR can add assured irrigation in specific deficit regions, but nationwide all-weather navigation is doubtful; a selective, link-by-link approach with strict appraisal is more realistic.Q6(b) · Cultural Setting and Population of India · 15 marks≈ 11 min

Religious minorities form about 20% of India’s population (Census 2011), but they are spatially concentrated along the frontier states: Muslims in Jammu and Kashmir (68.3%), Assam (34.2%) and West Bengal (27.0%); Sikhs in Punjab (57.7%); Christians in Nagaland (87.9%), Mizoram (87.2%) and Meghalaya (74.6%); Buddhists in Ladakh, Sikkim and Arunachal Pradesh. Lakshadweep (96.6% Muslim) is a maritime frontier.
Causes: (i) diffusion routes: Islam entered through the north-western passes and the Bengal delta; Tibetan Buddhism spread across the Himalaya. (ii) Partition (1947) drew the boundary through Punjab and Bengal, leaving mixed populations on both sides. (iii) Colonial policy of ‘excluded areas’ allowed missionary work in the north-eastern hills. (iv) Continued migration from Bangladesh into Assam and West Bengal. (v) Isolated hill and island settings protected distinct identities.
Consequences: security concerns, since cross-border ethnic and religious ties can be exploited by hostile states; identity-based movements and insurgency (Khalistan in the 1980s, Naga and Mizo insurgencies); contested citizenship issues such as the Assam NRC (final list of August 2019 excluded about 19 lakh people) and the Citizenship (Amendment) Act, 2019.
Positively, constitutional safeguards (Sixth Schedule, Articles 371A and 371G) and cultural links support soft-power diplomacy with neighbours, for example Buddhist circuits with Bhutan and Myanmar.
Map: Outline map of India shading border states and labelling the dominant minority and its share (Census 2011).
Inclusive development, border-area programmes such as the Vibrant Villages Programme (2023) and respect for identity are the way to turn these frontiers into bridges.Q6(c) · Contemporary Issues · 15 marks≈ 11 min
Pollution, Land-use Change and Environmental Impact Assessment
What do you understand by soil pollution? Delineate the areas vulnerable to it in India and suggest remedial measures.

मृदा प्रदूषण से आप क्या समझते हैं? भारत में मृदा प्रदूषण के प्रति संवेदनशील क्षेत्रों को निरूपित कीजिए तथा इसके उपचारात्मक उपाय सुझाइए।
Model answer
Paper and question: Paper II, Q6(c)
Approach: Define soil pollution, delineate vulnerable regions of India by cause (agrochemical, industrial, mining, irrigation-induced, geogenic, urban), and suggest remedial measures; draw a map of the vulnerable areas.
Soil pollution is the build-up of toxic chemicals, salts, heavy metals or pathogens in soil to levels that harm its fertility, organisms, crops and human health through the food chain and groundwater.
Agrochemical zones: Punjab, Haryana and western Uttar Pradesh use fertilisers in a skewed NPK ratio and heavy pesticide doses; residues and nitrates have built up in soils of the Malwa region, where a link with high cancer incidence is alleged but debated.
Irrigation-induced zones: waterlogging and salinity (usar, reh) in the Indira Gandhi Canal command, the Chambal and Sharda Sahayak commands and parts of Haryana.
Industrial and mining zones: the Vapi–Ankleshwar chemical belt (Gujarat), Patancheru (Telangana), chromium waste at Ranipet (Tamil Nadu) and Kanpur, chromite mining at Sukinda (Odisha), and coal and iron ore belts of Jharia, Singrauli, Bellary and Goa.
Geogenic and urban: arsenic carried by irrigation water into soils of West Bengal and Bihar, fluoride in Rajasthan, and landfill zones around metros.
Map: Map of India shading the Punjab–Haryana agrochemical belt and canal-command salinity patches, and marking Vapi, Ankleshwar, Patancheru, Ranipet, Kanpur, Sukinda, Jharia, Singrauli, Bellary and the arsenic belt of the lower Ganga.
Remedial measures: balanced fertiliser use guided by the Soil Health Card scheme (2015), neem-coated urea, integrated pest management, natural and organic farming, gypsum for sodic soils and drainage for waterlogged land, effluent treatment and zero liquid discharge in industrial clusters, mine reclamation, and bioremediation and phytoremediation of contaminated sites.
Since soil forms over centuries but can be poisoned in decades, prevention and a national soil-quality standard should be priorities.

Transport Networks and Regional Development
Integrated development of road and rail networks in a complementary framework is a prerequisite for regional development. Explain with reference to North-Eastern Region of India.
हिंदी में प्रश्न
सड़क और रेल जालतंत्रों का एक पूरक ढाँचे में एकीकृत विकास, प्रादेशिक विकास के लिए एक पूर्व-आवश्यकता है। भारत के पूर्वोत्तर प्रदेश के संदर्भ में इसको स्पष्ट कीजिए।
Model answer
Paper and question: Paper II, Q7(a)
Approach: Explain why road and rail must complement each other for regional development, apply this to the north-east (isolation, terrain, current projects for each mode and their integration), and conclude. Draw a map of north-eastern road and rail links.
Roads and railways have complementary strengths: railways move bulk goods and people cheaply over long distances, while roads give door-to-door and last-mile access in rugged areas. Regional development needs both, integrated through terminals and feeder roads, in line with Taaffe, Morrill and Gould's model of network-led regional growth.
The north-east's problem: the region is linked to the rest of India only through the narrow Siliguri corridor ('chicken's neck'), has hilly terrain, heavy rain, landslides and wide rivers such as the Brahmaputra, and for decades had a poor road density and metre-gauge or no railways. This isolation raised costs and limited markets.
Railways: gauge conversion to broad gauge across Assam and Tripura; new lines aiming to connect all state capitals, such as Bairabi–Sairang to Aizawl, Jiribam–Imphal and lines towards Kohima and Shillong; and the Bogibeel rail-cum-road bridge (2018) across the Brahmaputra.
Roads: the Special Accelerated Road Development Programme for the North East, Bharatmala and the Trans-Arunachal and Frontier Highways; the Dhola–Sadiya bridge (2017); and the Sela tunnel (2024).
Complementarity: (i) railways bring bulk goods (food grains, fuel, cement) to rail heads such as Guwahati, Dimapur and Agartala, and roads distribute them to hill districts; (ii) multimodal terminals and inland waterways on the Brahmaputra (NW-2) link the two; (iii) cross-border projects such as the Kaladan multimodal route and the Agartala–Akhaura rail link (2023) open routes through Myanmar and Bangladesh under the Act East Policy.
Developmental effects: better connectivity lowers prices, opens markets for horticulture and tourism, improves access to health and education and strengthens border security.
Challenges: landslides, earthquakes, high construction costs and ecological damage in fragile hills.
Map: Map of north-east India showing the Siliguri corridor, main highways and rail lines, new lines to state capitals, the Bogibeel and Dhola–Sadiya bridges, NW-2 and the Kaladan and Agartala–Akhaura links.
An integrated road–rail–waterway framework is therefore the key to unlocking the north-east's development.Q7(b) · Transport, Communication and Trade · 15 marks≈ 11 min

Model answer
Paper and question: Paper II, Q7(b)
Approach: Describe the salient features of Sagarmala (aim, pillars, components, institutions), then highlight its role in port-led development of coastal regions with examples and limits. Draw a map of Sagarmala components.
Sagarmala, approved in 2015, is India's flagship programme for port-led development, aiming to use the coastline and waterways to lower logistics costs for domestic and export cargo and to develop coastal regions.
Salient features: (i) four pillars: port modernisation, port connectivity, port-led industrialisation and coastal community development; (ii) a National Perspective Plan (2016) identifying projects; (iii) Coastal Economic Zones and port-linked industrial clusters; (iv) promotion of coastal shipping and inland waterways as cheaper alternatives to road and rail; (v) skill development, fishing harbours and coastal tourism; (vi) the Sagarmala Development Company to support projects through public–private partnership.
Role in port-led development: (i) new and expanded ports (Vadhavan, Vizhinjam, Paradip and JNPA expansions) attract industry and jobs; (ii) port rail and road links extend hinterlands; (iii) industrial clusters near ports, such as refineries, steel and cement units, reduce transport costs; (iv) coastal shipping and Ro-Pax ferries (Ghogha–Hazira, Mumbai–Mandwa) link coastal towns; (v) fishing harbours and skills programmes benefit coastal communities.
Limits: delays, slow progress of Coastal Economic Zones, and ecological and livelihood conflicts.
Map: Map of India's coast marking major ports, new ports, Coastal Economic Zones and coastal shipping routes.
Sagarmala can transform coastal regions if it balances growth with coastal ecology.Q7(c) · India: Physical Setting I · 15 marks≈ 11 min
Geological Structure and Relief
Justify the inclusion of Meghalaya in Peninsular India and discuss its vegetation and soil types.
हिंदी में प्रश्न
मेघालय को प्रायद्वीपीय भारत में सम्मिलित करने का औचित्य बताइए तथा वहाँ की वनस्पति एवं मृदा प्रकारों की विवेचना कीजिए।
Model answer
Paper and question: Paper II, Q7(c)
Approach: First justify, with structural, rock and relief evidence, that the Meghalaya plateau is a detached part of the Peninsular block; then describe its vegetation and soils with their controls. Draw a sketch map showing the Malda gap.
The Meghalaya (Shillong) plateau of the Garo, Khasi and Jaintia hills lies in the north-east but geologically belongs to the Peninsular block, separated from it by the alluvium-filled Malda (Garo–Rajmahal) gap.
Justification: (i) its core is Archaean gneiss and granite with Proterozoic Shillong Group quartzites, the same shield rocks as Chotanagpur; (ii) it is a stable, block-faulted horst, not folded like the Himalaya and Purvanchal; (iii) the Dauki fault on its southern edge and the down-faulted Malda gap, later filled by Ganga–Brahmaputra deposits, show how it was severed; (iv) its flat-topped, dissected surface resembles the Peninsular pat lands.
Vegetation: heavy orographic rain (Mawsynram and Sohra receive over 11,000 mm a year) supports tropical wet evergreen and semi-evergreen forests on the southern scarps and Garo hills (Nokrek Biosphere Reserve). The cooler central Khasi hills carry subtropical broadleaf and Khasi pine forests, and sacred groves such as Mawphlang preserve relict forest, while jhum has left grass and bamboo on degraded slopes.
Soils: intense leaching produces acidic red loamy and lateritic soils, laterite on plateau tops, organic-rich forest soils under dense cover, and alluvium in the Garo foothill valleys.
Map: Sketch map showing the Peninsular plateau, the Malda gap, the Meghalaya plateau with the Garo, Khasi and Jaintia hills, and the Dauki fault.
Meghalaya is thus a Peninsular block in a north-eastern setting, where ancient rocks and extreme rainfall together shape distinctive forests and leached soils.

Evolution of Industries and Industrial Regionalisation
Name the major industrial regions of India indicating the bases of their identification. Highlight their basic problems.
हिंदी में प्रश्न
भारत के प्रमुख औद्योगिक प्रदेशों के नाम, उनकी पहचान के आधारों को इंगित करते हुए, बताइए। उनकी मूलभूत समस्याओं पर प्रकाश डालिए।
Model answer
Paper and question: Paper II, Q8(a)
Approach: State the bases (criteria) for identifying industrial regions, name the major regions with their main industries, then highlight their common and specific problems. Draw a map of industrial regions.
An industrial region is an area where industries cluster densely with strong linkages. Indian regions are usually identified on the basis of the number of industrial units, the number of industrial workers, power used in industry, the value of industrial output and value added, often measured at district level (as in the NCERT classification of 8 major regions, 13 minor regions and 15 industrial districts).
Major industrial regions: (i) Mumbai–Pune: cotton textiles, petrochemicals, engineering, automobiles, pharmaceuticals; (ii) Hugli: jute, engineering, chemicals, paper; (iii) Bengaluru–Tamil Nadu: IT, aircraft, automobiles (Chennai, Hosur), textiles (Coimbatore, Tiruppur); (iv) Gujarat: textiles (Ahmedabad, Surat), petrochemicals and refining (Jamnagar, Vadodara, Ankleshwar), pharmaceuticals; (v) Chotanagpur: iron and steel (Jamshedpur, Bokaro, Durgapur), coal-based industries, heavy engineering; (vi) Visakhapatnam–Guntur: shipbuilding, steel, refining, fertilisers; (vii) Gurugram–Delhi–Meerut: automobiles, electronics, light engineering; (viii) Kollam–Thiruvananthapuram: coir, cashew, rubber products and IT.
Common problems: congestion, slums and pollution in metropolitan cores; high land and labour costs; shortage of water and power; and pressure on transport.
Specific problems: the Hugli region suffers from declining jute mills, obsolete plants, labour unrest and siltation of Kolkata port; Mumbai has seen textile mill closures since the 1980s and land scarcity; Chotanagpur faces mining-related displacement, pollution, Left-wing extremism and weak diversification; and Gujarat's Golden Corridor (Vapi, Ankleshwar) has severe industrial pollution.
Regional imbalance: industry remains concentrated in a few regions, leaving much of the north-east, Bihar, eastern Uttar Pradesh and central India industrially backward.
Map: Map of India marking the eight major industrial regions with their key centres and dominant industries.
Decongestion, modernisation, clean technology and new corridors that take industry to lagging regions can address these problems.Q8(b) · India: Physical Setting I · 15 marks≈ 11 min
Drainage Systems and Watersheds
Drainage pattern in Peninsular India is a result of its geological structure and topography. Elaborate.
हिंदी में प्रश्न
प्रायद्वीपीय भारत में अपवाह प्रतिरूप उसकी भूवैज्ञानिक संरचना एवं स्थलाकृति का परिणाम है। सविस्तार स्पष्ट कीजिए।
Model answer
Paper and question: Paper II, Q8(b)
Approach: Show, region by region, how structure (tilt, rifts, domes, rock type) and relief explain each Peninsular drainage feature and pattern. Draw a map of Peninsular drainage with the water divide.
Peninsular India is an ancient, rigid block, and its drainage has adjusted over a long time to its structure (tilts, faults and rock types) and topography, making it a classic example of structural control.
Eastward tilt: uplift of the western edge raised the Western Ghats as the main water divide close to the west coast, so the Mahanadi, Godavari, Krishna and Kaveri flow east across the whole plateau, while western slopes have short, parallel, swift streams.
Rift valleys: the Narmada and Tapi flow west through fault troughs against the general slope, and the Damodar flows east through a Gondwana rift, showing that faults override the regional tilt.
Domes and northward slope: radial drainage spreads from the Amarkantak plateau (Narmada, Son, Mahanadi) and the Ranchi–Hazaribagh plateau, while the Chambal, Betwa and Ken flow north down the slope of the Malwa and Bundelkhand plateaus to the Yamuna.
Rock type: dendritic patterns develop on the uniform Deccan basalt and granite, trellis and rectangular patterns on folded and jointed rocks of the Singhbhum and Vindhyan regions, and waterfalls where rivers cross hard scarps (Jog, Hundru, Dhuandhar).
Maturity: long erosion over hard rocks has produced broad, graded valleys with low gradients, except at scarps and gorges.
Map: Map of Peninsular India showing the Western Ghats divide, east-flowing rivers, the Narmada–Tapi rifts, the Damodar trough and radial drainage from Amarkantak.
Peninsular drainage is therefore largely an expression of geology, unlike the antecedent Himalayan rivers.Q8(c) · Resources of India · 15 marks≈ 11 min
Energy Resources and the Energy Crisis
Why has solar energy in India not been developed to desired level in spite of its high potential?
हिंदी में प्रश्न
क्या कारण है कि भारत में सौर ऊर्जा की उच्च संभाव्यता के होते हुए भी उसको वांछित स्तर तक विकसित नहीं किया गया है?
Model answer
Paper and question: Paper II, Q8(c)
Approach: Acknowledge the high potential, then examine the technical, economic, institutional and environmental reasons for slow development (as of 2017 and still partly today), and note the progress since. Draw a map of solar potential and parks.
India's solar potential is estimated at about 748 GW (NISE), yet in 2017 installed capacity was only around 12 GW, and the 2022 target of 100 GW (including 40 GW rooftop) was missed by a wide margin.
Economic reasons: high upfront capital cost and costly finance; the poor finances of DISCOMs, which delayed payments and sometimes renegotiated tariffs; and low tariffs that squeezed developers.
Technical reasons: intermittency and lack of affordable storage; inadequate transmission from sunny western states; and efficiency losses from heat and dust.
Manufacturing dependence: most cells and modules were imported from China, exposing projects to price swings, safeguard duties and supply disruptions.
Institutional reasons: slow land acquisition, complex approvals, net-metering rules that discouraged rooftop solar, and weak consumer awareness.
Environmental and social issues: large land requirements in arid grasslands, water for panel cleaning, and wildlife conflicts; for example, the Supreme Court in 2021 ordered undergrounding of power lines in great Indian bustard habitats.
Progress since: solar parks, falling costs, PLI for manufacturing and rooftop schemes raised capacity to about 165 GW by July 2026 (MNRE), though storage and rooftop adoption still lag.
Map: Map of India shading high-insolation zones and marking major solar parks and the bustard habitat in Rajasthan.
Fixing finance, grids and storage is key to realising the full potential.
