Chapter 1: Locational Setting of India

On a clear January morning the sun clears the eastern hills of Arunachal Pradesh, and the tea gardens below are already at work. Almost two hours later, the same sun edges over the salt flats of the Rann of Kachchh, in the far west of Gujarat. Two places, one country, one date on the calendar — and yet, for a while, one stands in daylight while the other still waits in the dark.

The reason lies in a plain fact about the turning earth. India stretches across nearly thirty degrees of longitude, from about 68° East to 97° East. The earth spins once through 360° in twenty-four hours, so every degree of longitude is worth four minutes of time. Thirty degrees, then, come to about two hours — exactly the gap between an Arunachal dawn and a Kachchh dawn.

Long ago the tea planters of Assam noticed this. Their working day began well before the rest of the country agreed it was morning, so the gardens quietly kept their own clock, running about an hour ahead of the national time. People there still call it ‘bagan time’ — garden time. Every few years someone asks whether the north-east should have a time zone of its own, and every few years the country decides to keep a single clock instead.

That one clock, the shape of India’s frontiers, and its long reach into the Indian Ocean all follow from a single thing: where on the globe India happens to sit.

NoteCuriosity Corner

Q1. Why does the sun rise almost two hours earlier in the far east of India than in the far west? Q2. If the whole of India keeps one clock, which line of longitude is that clock set by, and why was that line chosen? Q3. How large is India compared with other countries — is it a big country, a small one, or something in between? Q4. With how many countries does India share a land frontier, and which of them is the longest? Q5. Why is India called a subcontinent, and what does its position in the Indian Ocean give it?

By the end of this chapter you will be able to answer each of these from India’s place on the globe.

1.1 India as a Subcontinent

India lies wholly north of the Equator and east of the Prime Meridian — that is, in the Northern and Eastern Hemispheres of the globe. It sits in the south of Asia, the largest of the continents, and forms the heart of the region called South Asia.

What sets India apart from the rest of Asia is the frame around it. To the north stands the wall of the Himalayas, the highest mountain range on earth. To the south, west and east the land runs out into water — the Indian Ocean, with the Arabian Sea on one flank and the Bay of Bengal on the other. Mountains on one side and sea on the other three enclose a landmass with clear, hard edges.

A landmass so framed, so large and so varied is called a subcontinent — a major landmass smaller than a full continent, yet marked off from the rest of it by physical barriers and large and diverse enough to carry the full range of features a continent has. The whole unit, which includes India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka, is the Indian subcontinent.

Map

Map 1.1 Caption: India sits in the south of Asia, walled off by the Himalayas and open to the sea on three sides. Brief: Show India within southern Asia, drawn to its full extent as officially defined by the Government of India (including Jammu and Kashmir and Ladakh). Mark the Himalayas as a continuous mountain belt along the northern boundary. Label the Arabian Sea, the Bay of Bengal and the Indian Ocean. Show and label the neighbouring countries of the subcontinent — Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka. Shade India distinctly from its neighbours. Do not show any part of India as disputed or as belonging to another state.

India earns the name on four counts. It is vast — its area alone places it among the largest countries on earth, as Section 1.4 will show. It is physically diverse — within one country lie the world’s highest mountains, a great river plain, a hot desert, an ancient plateau and long tropical coasts. It has a climate of its own — the seasonal reversal of winds called the monsoon, the rain-bearing system on which the whole region depends. And it is set apart by barriers few other regions match: an almost unbroken mountain rampart in the north and open ocean on three sides.

That northern wall is not an accident of the map. The Himalayas rose, and are still rising, where the Indian landmass drove into the rest of Asia and buckled the crust upward — a collision you will meet again when you study the structure of India. Until aircraft and modern roads, this rampart made overland movement into the subcontinent slow and narrow, while the open sea to the south made movement by water easy. A barrier on one side and a highway of water on the other have shaped India’s history as much as its geography.

Map 1.1 The shaded area is India; the ring of mountains and sea around it is the frame that marks the subcontinent off from the rest of Asia. Trace the Himalayas along the north and the three seas around the peninsula. What the map cannot show at this scale is the internal variety — plain, desert, plateau and coast packed inside that outline — which is the real reason India is called a subcontinent and not simply a large country.

The physical variety named above — the mountains, the plains, the desert, the plateau and the coasts — is the subject of the chapters that follow. Here it is enough to see that each is large and distinct in its own right, and that together they give one country the reach of a continent.

1.2 The Latitudinal and Longitudinal Extent

Every point on the earth is fixed by two angles. Latitude is the angular distance of a place north or south of the Equator, measured in degrees, with the Equator at 0° and each Pole at 90°. Longitude is the angular distance of a place east or west of the Prime Meridian, the line of 0° that runs through Greenwich. Together the two angles pin any place to a single spot on the globe.

India’s reach in each direction is close to thirty degrees — a wide sweep for a single country. That reach, north to south and east to west, decides how much of the sun’s variety the country receives, and by how much its clocks would differ if every town kept its own local time.

1.2.1 Latitudinal Extent

The mainland of India extends from 8°4’ North to 37°6’ North. The northernmost point, Indira Col, lies in the far north of Jammu and Kashmir; the southernmost point of the mainland is Kanniyakumari, the tip of the peninsula in Tamil Nadu. The Republic reaches further south still: Indira Point, at 6°45’ North on Great Nicobar in the Andaman and Nicobar Islands, is the southernmost point of Indian territory.

The latitudinal spread of the mainland is therefore about 29°, close to one-third of the 90° that separate the Equator from the North Pole. For a single country that is a long reach across the face of the earth.

Latitude fixes the angle at which the noon sun strikes the ground, so this spread has real effects. The far south lies within the tropics, where the sun climbs nearly overhead and the year stays warm. The far north lies well beyond them, high and cold enough for the mountains to hold snow through much of the year. One country thus runs from tropical to near-temperate conditions — and the length of day, too, varies more from north to south than any smaller country would know. You will trace these effects in full when you study India’s climate.

1.2.2 Longitudinal Extent

India extends from 68°7’ East to 97°25’ East — again a span of about 29°, or roughly one-twelfth of the 360° that make a full circle of longitude. The western edge lies near the Rann of Kachchh in Gujarat; the eastern edge lies in Arunachal Pradesh.

This east–west reach has one large consequence. Because the earth turns from west to east, places lying to the east meet the sun first. A spread of nearly thirty degrees of longitude therefore means a genuine difference in the timing of sunrise and sunset across the country — a difference we measure, and then decide what to do about, in Section 1.3.

1.2.3 North–South and East–West Distances

Turned into ground distance, India measures 3,214 km from Indira Col in the north to Kanniyakumari in the south, and 2,933 km from the Rann of Kachchh in the west to Arunachal Pradesh in the east.

Map

Map 1.2 Caption: The extremities of India, its north–south and east–west spans, the Tropic of Cancer and the standard meridian. Brief: Draw India to its full extent as officially defined by the Government of India (including Jammu and Kashmir and Ladakh), with a latitude–longitude grid along the border. Mark the extremities: northernmost Indira Col (37°6’ North), southernmost point of the mainland Kanniyakumari (8°4’ North), southernmost point of the Republic Indira Point on Great Nicobar (6°45’ North), western edge near the Rann of Kachchh (68°7’ East) and eastern edge in Arunachal Pradesh (97°25’ East). Show a double-headed arrow for the north–south distance labelled 3,214 km and one for the east–west distance labelled 2,933 km. Draw the Tropic of Cancer (23°30’ North) as a horizontal dashed line and the standard meridian (82°30’ East) as a vertical dashed line. Label the Arabian Sea, the Bay of Bengal and the Indian Ocean. Do not show any part of India as disputed or as belonging to another state.

Notice that the two figures are not equal, even though the angular extent — about 29° each way — is almost the same. India reaches nearly as far in degrees east–west as north–south, yet covers about 280 km more on the ground from north to south. The reason lies in the shape of the grid of latitude and longitude itself.

Worked Case 1.1 — Why India Is Taller Than It Is Wide The situation: India’s angular reach is almost equal each way (about 29°), yet its north–south ground distance (3,214 km) is greater than its east–west distance (2,933 km). The working: Latitudinal extent \(= 37°6' - 8°4' = 29°2' \approx 29°\). One degree of latitude covers nearly the same ground everywhere, about 111 km. So \(29 \times 111\ \text{km} = 3{,}219\ \text{km}\), close to the measured 3,214 km. Longitudinal extent \(= 97°25' - 68°7' = 29°18' \approx 29°\). One degree of longitude is 111 km only at the Equator. Away from it the meridians draw together, and a degree shrinks as \(111\ \text{km} \times \cos(\text{latitude})\), where the latitude is how far north or south the measurement is taken. Across India’s middle, near 23° North, \(\cos 23° \approx 0.92\), so a degree is about \(111 \times 0.92 \approx 102\ \text{km}\). That gives \(29 \times 102\ \text{km} \approx 2{,}958\ \text{km}\); because much of India’s width is measured north of 23° North, the true figure is a little less — 2,933 km.

The lesson outlives the arithmetic. Equal angles do not mean equal distances. Lines of longitude fan out from the poles and meet there, so each degree of longitude is worth fewer kilometres the further you go from the Equator, while each degree of latitude stays near 111 km throughout. A country can look almost square on a grid and still be taller than it is wide on the ground — which is exactly the trap a map’s tidy squares can set for a careless reader.

Map 1.2 The four labelled points are India’s extremities; the two double-headed arrows give the ground distances between them. The horizontal dashed line is the Tropic of Cancer, the vertical dashed line the standard meridian at 82°30’ East. Read position from the degree grid along the edges. What the evenly spaced grid hides is that a degree of longitude here covers less ground than a degree of latitude — so equal squares are not equal distances.

1.3 Position, Time and the Standard Meridian

Extent tells us how far India reaches. Position tells us where those reaches fall against the globe’s important lines — the Tropic of Cancer across its middle, and the meridian by which the whole country sets its clock.

1.3.1 The Tropic of Cancer

The Tropic of Cancer is the parallel at 23°30’ North, the northernmost latitude at which the noon sun is ever directly overhead — it stands overhead here once a year, at the June solstice, and never any further north. This line runs almost through the middle of India, and on its way crosses eight states: Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura and Mizoram. You can see it on Map 1.2 as the horizontal dashed line.

The Tropic splits the country into two climatic halves. South of it lies tropical India, where the sun climbs high all year and the heat is steady. North of it lies subtropical India, where winters turn cooler and the sun sits lower in the sky. Because the line falls near the centre, India belongs to both worlds at once — a tropical south joined to a subtropical, mountain-walled north. The full working-out of this belongs to the chapter on climate.

1.3.2 Longitude, Time and Indian Standard Time

The local time of a place is the time read from the sun’s own position: noon is the moment the sun stands highest there. Because the earth turns from west to east, the sun reaches eastern places first, so their local time runs ahead of places lying to the west.

How far ahead? The earth turns once — a full 360° — in 24 hours:

\[\frac{360°}{24\ \text{hours}} = 15°\ \text{of longitude per hour}\]

So one degree of longitude is worth four minutes of time. India spans nearly 30° of longitude, which comes to about \(30 \times 4 = 120\) minutes, or two hours. The far east therefore sees the sun rise roughly two hours before the far west.

Flowchart

Fig. 1.3-1 Caption: How a span of longitude becomes a two-hour gap, and why India settles on a single clock. Nodes: Earth turns 360° in 24 hours → 15° of longitude per hour → 1° of longitude = 4 minutes of time → India spans nearly 30° of longitude → local times across the country would differ by about 2 hours east to west → adopt one standard meridian at 82°30’ East → the whole country keeps Indian Standard Time, 5 hours 30 minutes ahead of Greenwich

Q1. Why does the sun rise almost two hours earlier in the far east of India than in the far west?

A. India spans nearly 30° of longitude, and the earth turns from west to east. Each degree is worth four minutes of time, so 30° is about two hours — the eastern edge meets the sun that much before the western edge.

A country cannot run on two hours’ worth of different clocks. Railways would misconnect, broadcasts would clash, and offices in one city would open as another closed. To prevent this, India keeps a single Indian Standard Time (IST) for the whole country, set to the local time of one chosen line — the standard meridian at 82°30’ East.

Two reasons make 82°30’ East the sensible choice. It runs close to the centre of the country, near Mirzapur in Uttar Pradesh, so no place — east or west — is thrown too far out of step with its own sun. And it sits a convenient distance from the world’s reference clock: 82°30’ is 82.5°, and \(82.5 \times 4 = 330\) minutes, so IST stands exactly five hours thirty minutes ahead of Greenwich Mean Time, the reference time kept at 0° longitude.

Q2. If the whole of India keeps one clock, which line of longitude is that clock set by, and why was that line chosen?

A. It is set by the standard meridian, 82°30’ East. That line runs roughly through the middle of the country, so no place is too far out of step, and it puts Indian Standard Time a neat five and a half hours ahead of Greenwich.

The single clock is a convenience bought at a price, and the price falls unevenly. In the far east the sun rises very early and sets early, but the clock — tuned to a meridian far to the west — insists it is still mid-morning or mid-afternoon. This is why the tea gardens of Assam long kept their own bagan time, and why a demand for a separate eastern time zone returns every few years. Whether to keep one clock or two is a real and open question, weighing convenience against wasted daylight and energy.

Who Should The Clock Follow? Workers in the far east: in summer the sun is up by 4 a.m., yet the clock reads far earlier — daylight is lost to sleep and evenings darken early. Railways and broadcasters: one clock stops thousands of timetables colliding. Both agree: the eastern sun really does run ahead of the standard clock. What would you need to know to decide? Whether the daylight and energy saved would outweigh the cost and confusion of running two zones.

1.4 Size and Area

India covers 3,287,263 km² — about 2.4 per cent of the total land area of the world. That single figure places it seventh among the countries of the earth. Six countries are larger; every other nation is smaller.

The six that exceed India are Russia, Canada, the United States, China, Brazil and Australia. Set out by area, the order and the gaps between them tell the story better than any sentence.

Table 1.1 — The Seven Largest Countries By Area (approximate area, million km²) | Country | Area (million km²) | |—|—| | Russia | 17.10 | | Canada | 9.98 | | United States | 9.83 | | China | 9.60 | | Brazil | 8.52 | | Australia | 7.69 | | India | 3.29 |

Read down the column and the shape of the ranking appears. Russia stands far above the rest, about five times the size of India. Canada, the United States and China are each roughly three times India’s area. India sits clearly below the giants — yet it is no small country.

Table 1.1 The right-hand column is area in million square kilometres; the countries are ranked largest first, with India at the foot. Read down and the gap is clear — Russia stands far above the rest, and six countries exceed India. What the ranking does not settle is the middle order: the United States and China are so close that which comes third depends on how inland waters are counted.

Looked at the other way, India towers over most of the world’s states. It is about four times the size of Pakistan, six times that of France, nine times that of Germany, and more than twenty times the size of Bangladesh. Against the ordinary run of nations, India is a very large country indeed.

Between these two views lies the truth: India is, in the common phrase, neither a pigmy nor a giant among the world’s nations. It is too large to be a minor state and too small to sit with the handful of continental giants.

Size is not merely a matter of standing. A country this large is bound to be varied — across 3,287,263 km² lie many climates, soils, crops and peoples, the raw material of a subcontinent. But size cuts both ways. The same distances that give India its variety also make it harder to govern, to connect by road and rail, and to serve with power, water and markets from one end to the other. Area measures not only a country’s importance, but also the sheer task of holding it together.

Q3. How large is India compared with other countries — is it a big country, a small one, or something in between?

A. India is the seventh largest country on earth, covering 3,287,263 km², about 2.4 per cent of the world’s land. Six countries are bigger, yet India is several times the size of most nations — neither a pigmy nor a giant.

1.5 Frontiers and the Coastline

A country’s frontiers are its edges — the lines where its land meets other lands, and where its land meets the sea. India has both kinds in plenty: a land frontier shared with seven neighbours, and one of the longer coastlines in the world.

1.5.1 Land Frontiers with Neighbouring Countries

India shares a land frontier with seven countries — a frontier being the outer boundary where one country’s territory meets another’s. In the west and north-west lie Pakistan and Afghanistan; along the northern mountains lie China, Nepal and Bhutan; to the east lie Bangladesh and Myanmar.

Map

Map 1.3 Caption: India’s seven land neighbours and its long coastline on the Indian Ocean. Brief: Draw India to its full extent as officially defined by the Government of India (including Jammu and Kashmir and Ladakh). Show and label the seven neighbouring countries that share a land frontier — Pakistan and Afghanistan to the west and north-west, China, Nepal and Bhutan to the north, and Bangladesh and Myanmar to the east. Show and label the island neighbours across the sea, Sri Lanka and the Maldives. Mark the international land boundary as a distinct line and the coastline clearly. Label the Arabian Sea, the Bay of Bengal and the Indian Ocean. Do not show any part of India as disputed or as belonging to another state.

The total length of India’s land boundary is about 15,107 km, as measured by the Ministry of Home Affairs. That length is not shared evenly. Bangladesh accounts for the longest single stretch, Afghanistan the shortest.

Table 1.2 — India’s Land Boundary With Its Neighbours (Ministry of Home Affairs figures) | Neighbouring country | Length of border (km) | Share of total (%) | |—|—|—| | Bangladesh | 4,096.7 | 27.1 | | China | 3,488 | 23.1 | | Pakistan | 3,323 | 22.0 | | Nepal | 1,751 | 11.6 | | Myanmar | 1,643 | 10.9 | | Bhutan | 699 | 4.6 | | Afghanistan | 106 | 0.7 | | Total | 15,106.7 | 100.0 |

Table 1.2 The middle column is the length of each land border in kilometres; the right column is each as a share of the 15,106.7 km total. Read top to bottom: three neighbours — Bangladesh, China and Pakistan — together account for over seven-tenths of the whole. What the length cannot tell you is how settled or disputed each stretch is; a long quiet border and a short tense one look exactly alike here.

Q4. With how many countries does India share a land frontier, and which of them is the longest?

A. India shares a land frontier with seven countries: Bangladesh, China, Pakistan, Nepal, Myanmar, Bhutan and Afghanistan. The longest is with Bangladesh, about 4,097 km; the shortest is with Afghanistan, about 106 km.

The Bangladesh border is long partly because Bangladesh nearly wraps around India’s north-east, meeting it on three sides. The short 106 km stretch with Afghanistan lies along the far north-western extremity of Jammu and Kashmir. Beyond these land neighbours, India has island neighbours it meets by water rather than by land: Sri Lanka, across the narrow Palk Strait, and the Maldives, further out in the Arabian Sea.

1.5.2 The Coastline

The coastline of the mainland runs for about 6,100 km. Adding the shores of the two island groups — the Andaman and Nicobar Islands in the Bay of Bengal and the Lakshadweep Islands in the Arabian Sea — brings India’s total coastline to 7,516.6 km.

A long coastline is a standing asset. It offers natural harbours and major ports, an open door to the sea routes of the world, and rich fishing grounds along the continental shelf. Among the states, Gujarat has the longest coastline of any.

A coast is also a responsibility. It must be kept clear for shipping, guarded against smuggling and intrusion, and defended against the storms and slow erosion that eat at any shore. The reach of that coast into the Indian Ocean — and what it has meant for India’s place in the world — is the subject of the next section.

1.6 The Locational Advantages of India

A country’s location is not merely where it is, but what that place allows it to do. India’s position — a subcontinent set at the head of a great ocean — has shaped its trade, its history and its cultural reach far beyond what its size alone would grant.

1.6.1 India and the Indian Ocean

India stands at the northern head of the Indian Ocean, with the peninsula reaching far south into it. This is no ordinary position. The Indian Ocean is the only one of the world’s oceans named after a single country — a sign of the prominence India held in the age when the oceans were being named.

The sea routes that cross this ocean must skirt India’s shores. Ships moving between Europe, West Asia and Africa in the west, and Southeast Asia, East Asia and Australia in the east, pass close to the projecting Indian peninsula. From its western coast India reaches out towards West Asia, Africa and Europe; from its eastern coast towards Southeast Asia, the Far East and Australia. In this sense India commands trade routes running in every direction.

A country lying along a sea is called a littoral country, and India is the leading littoral state of the Indian Ocean. Around that ocean lies a ring of coastal nations across Asia, Africa and Australia — the Indian Ocean Rim — and India sits near its centre. Since the opening of the Suez Canal in 1869, which cut a short water route from the Mediterranean into the Red Sea, Southern Europe and North Africa have been brought closer to India than ever before.

Map

Map 1.4 Caption: India stands at the head of the Indian Ocean, on the sea route between the western and eastern worlds. Brief: Show India at the northern head of the Indian Ocean, drawn to its full extent as officially defined by the Government of India (including Jammu and Kashmir and Ladakh). Show the Arabian Sea to India’s west and the Bay of Bengal to its east. Mark the main sea routes: westward towards West Asia, the Red Sea, the Suez Canal and Europe and Africa; eastward towards Southeast Asia, East Asia and Australia. Label the Suez Canal. Show the ring of Indian Ocean Rim countries lightly around the ocean. Use boundaries as officially recognised by the Government of India, and do not show any part of India as disputed.

Why India Commands The Indian Ocean Factors: a central northern position on the ocean; a peninsula reaching about 1,600 km southward; long coasts on both the Arabian Sea and the Bay of Bengal; a place astride the route between West and East. The decisive one: the projecting central position — ships sailing between Europe and East Asia must pass close by India. Move it: were India a small inland country, those routes would run far to its south and pass it by.

Q5. Why is India called a subcontinent, and what does its position in the Indian Ocean give it?

A. It is a subcontinent because it is vast, physically varied and walled off from the rest of Asia by the Himalayas and the sea. Its position gives it command of the Indian Ocean — the sea routes between West and East must skirt its shores.

1.6.2 Strategic and Cultural Significance

India’s central position turns geography into influence. In earlier centuries it was the principal entrepôt of the Indian Ocean — a trading hub where goods were gathered, exchanged and sent onward — and this role, together with its wealth, drew traders and, later, colonial powers towards it. Its value to the British Empire earned it the description ‘jewel in the crown’, and its command of the eastern sea lanes the older title ‘Mistress of the Eastern Seas’.

The same routes carried ideas as well as goods. Over two thousand years, contact by sea spread Indian religions and cultural forms eastward: Buddhism and Hinduism reached Southeast Asia, temples in Thailand carry carved scenes from the Ramayana, and the island of Bali in Indonesia keeps a Hindu culture to this day. Movement across the ocean was never one-way, but India’s location placed it at the crossroads of much of it.

That strategic weight has not faded. A large share of the world’s shipborne trade and energy crosses the northern Indian Ocean, and many of the air routes between Europe, West Asia and the countries of the east pass over India. Its place among the Indian Ocean Rim countries — for trade, for the security of the sea lanes, and for cooperation across the region — flows directly from where it sits on the map. Location, here, is not a background fact but an active advantage.

1.7 Summary

  1. India is a subcontinent — a landmass large and varied enough to hold a continent’s range of features, yet marked off from the rest of Asia by the Himalayas in the north and the sea on three sides. It is the physical variety, not the size alone, that earns the name.

  2. Every place is fixed by two angles: latitude north or south of the Equator, and longitude east or west of the Prime Meridian. India’s mainland reaches from 8°4’ North to 37°6’ North and from 68°7’ East to 97°25’ East — close to 30° each way.

  3. Because latitude sets the angle of the noon sun, this spread carries India from the tropics in the south to near-temperate, snow-holding heights in the north. The southernmost point of the Republic is Indira Point (6°45’ North) on Great Nicobar, further south than the mainland tip at Kanniyakumari.

  4. Though the angular reach is nearly equal each way, India is longer north–south (3,214 km) than east–west (2,933 km), because a degree of longitude shrinks away from the Equator while a degree of latitude stays near 111 km.

  5. The Tropic of Cancer (23°30’ North) runs through the middle of India, crossing eight states and dividing a tropical south from a subtropical north.

  6. The east–west span of longitude means the sun rises about two hours earlier in the far east than in the far west. To keep one clock, India sets Indian Standard Time by the standard meridian at 82°30’ East — near the country’s centre and five and a half hours ahead of Greenwich.

  7. India covers 3,287,263 km², about 2.4 per cent of the world’s land, and is the seventh largest country. Six are bigger, most are smaller — neither a pygmy nor a giant. Area, though, measures only ground, not people, wealth or power.

  8. India shares a land frontier with seven neighbours; the longest is with Bangladesh, the shortest with Afghanistan, and the whole land boundary runs to just over 15,000 km.

  9. The coast runs about 6,100 km along the mainland and about 7,516.6 km with the islands. The peninsula juts roughly 1,600 km into the ocean, splitting it into the Arabian Sea and the Bay of Bengal.

  10. India stands at the head of the Indian Ocean — the only ocean named after a country — where the sea routes between West and East must skirt its shores. As a littoral state near the centre of the Indian Ocean Rim, this projecting position has long given India command of trade and a strategic and cultural reach, from its early role as an entrepôt to the present day.

What This Chapter Cannot Tell You

A single area figure or one coastline length hides how varied the ground behind it is: the same 2.4 per cent of the world holds mountain, desert, plain and coast, and this chapter’s numbers say nothing of that variety.

The two-hour daylight gap is drawn between the country’s outer edges; it does not tell you how any one town actually lives with a clock set far away.

And a good location is only an opportunity. The map shows where the advantage lies; it cannot show whether a country reaches out and takes it.

  5. Indian subcontinent — the whole subcontinent that includes India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.

  6. latitude — the angular distance of a place north or south of the Equator, measured in degrees.

  7. littoral — lying along a sea coast; a littoral state is one whose land borders an ocean.

  8. local time — the time read from the sun’s own position at a place, with noon at the moment the sun stands highest.

  9. longitude — the angular distance of a place east or west of the Prime Meridian, measured in degrees.

  10. standard meridian — the line of longitude (82°30’ East for India) whose local time a country adopts as its single official time.

  11. subcontinent — a large, physically distinct landmass, smaller than a continent but marked off by barriers and varied enough to hold a continent’s range of features.

  12. Tropic of Cancer — the parallel at 23°30’ North, the northernmost latitude at which the noon sun is ever directly overhead.

1.9 Points to Ponder

  1. India reaches nearly the same number of degrees east–west as north–south, yet is clearly longer on the ground from north to south. If two countries covered exactly the same span of degrees, could one still be much larger in square kilometres than the other? What would decide it?

  2. A single clock keeps the whole country in step, but leaves the far east’s mornings out of joint with its own sun. Is a shared national time worth more than a clock that matches the daylight where you live? Would your answer be the same for a farmer, a broadcaster and a stock exchange?

  3. Australia is more than twice the size of India but holds far fewer people. If area measures only ground, which other measures would you use to decide how ‘big’ a country really is — and could two honest measures ever rank the same countries differently?

  4. India’s command of the Indian Ocean grew when the world’s trade moved by sea. Can a place be well located for one age and badly located for the next? What kinds of change — in technology, in trade, in the routes people use — could make the very same position matter more, or matter less?

  5. If the length of a coastline depends on how finely you choose to measure it, is there any single true figure for how long India’s coast is? What length should a textbook print — and how should it explain the choice to a reader?
