The Physical Geography

The landmass of South Asia was formed by the Indian Plate colliding with the Eurasian Plate. This action started about seventy million years ago and gave rise to the highest mountain ranges in the world. Most of the South Asian landmass is formed from the land in the original Indian Plate. Pressure from tectonic action against the plates causes the Himalayas to rise in elevation by as much as one to five millimeters per year. Destructive earthquakes and tremors are frequent in this seismically active realm. The great size of the Himalayas has intensely influenced the beliefs and traditions of the people in the realm. Some of the mountains are considered sacred to certain religions that exist here.

The Himalayan Mountains dominate the physical landscape in the northern region of South Asia. Mt. Everest is the tallest peak in the world, at 29,035 feet. Three key rivers cross South Asia, all originating from the Himalayas. The Indus River, which has been a center of human civilization for thousands of years, starts in Tibet and flows through the center of Pakistan. The Ganges River flows through northern India, creating a core region of the country. The Brahmaputra River flows through Tibet and then enters India from the east, where it meets up with the Ganges in Bangladesh to flow into the Bay of Bengal. While the northern part of this region includes some of the highest elevations in the world, the Maldives in the south has some of the lowest elevations, some barely above sea level. The coastal regions in southern Bangladesh also have low elevations. When the seasonal reversal of winds called the monsoon arrives every year, there is heavy flooding and its effect on the infrastructure of the region is disastrous. The extensive Thar Desert in western India and parts of Pakistan, on the other hand, does not receive monsoon rains. In fact, much of southwest Pakistan—a region called Baluchistan—is dry, with desert conditions.

The mountains on the border between Pakistan and Afghanistan extend through Kashmir and then meet up with the high ranges of the Himalayas. The Himalayas create a natural barrier between India and China, with the kingdoms of Nepal and Bhutan acting as buffer states with Tibet. Farther south along the east and west coasts of India are shorter mountain ranges called ghats. The Western Ghats reach as high as eight thousand feet, but average around three thousand feet. These ghats are home to an extensive range of biodiversity. The Eastern Ghats are not as high as the Western Ghats, but have similar physical qualities. The ghats provide a habitat for a wide range of animals and are also home to large coffee and tea estates. The Deccan Plateau lies between the Eastern and Western Ghats. The Central Indian Plateau and the Chota-Nagpur Plateau are located in the central parts of India, north of the two Ghat ranges. The monsoon rains ensure that an average of about fifty-two inches of rain per year falls on the Chota-Nagpur Plateau, which has a tiger reserve and is also a refuge for Asian elephants.

The Monsoon

A monsoon is a seasonal reversal of winds that is associated with heavy rains. The summer monsoon rains—usually falling between June and September—feed the rivers and streams of South Asia and provide the water needed for agricultural production. In the summer, the continent heats up, with the Thar Desert fueling the system. The rising hot air creates a vacuum that pulls in warm moist air from the Bay of Bengal and the Indian Ocean. This action shifts moisture-laden clouds over the land, where the water is precipitated out in the form of rain.

Figure 9.3 The Monsoon System in South Asia

The monsoon rains bring moisture to South Asia right up to the Himalayas. As moisture-laden clouds rise in elevation in the mountains, the water vapor condenses in the form of rain or snow and feeds the streams and basins that flow into the major rivers, such as the Brahmaputra, Ganges, and Indus. The Western Ghats creates a similar system in the south along the west coast of India. Parts of Bangladesh and eastern India receive as much as six feet of rain during the monsoon season, and some areas experience severe flooding. The worst-hit places are along the coast of the Bay of Bengal, such as in Bangladesh. There is less danger of flooding in western India and Pakistan, because by the time the rain clouds have moved across India they have lost their moisture. Desert conditions are evident in the west, near the Pakistan border in the great Thar Desert. On average, fewer than ten inches of rain fall per year in this massive desert. On the northern rim of the region, the height of the Himalayas restricts the warm moist monsoon air from moving across the mountain range. The Himalayas act as a precipitation barrier and create a strong rain shadow effect for Tibet and Western China. The monsoon is responsible for much of the rainfall in South Asia.

By October, the system has run its course and the monsoon season is generally over. In the winter, the cold, dry air above the Asian continent blows to the south, and the winter monsoon is characterized by cool, dry winds coming from the north. South Asia experiences a dry season during the winter months. A similar pattern of rainy summer season and dry winter season is found in other parts of the world, such as southern China and some of Southeast Asia. A final note about the monsoons: small parts of South Asia, such as Sri Lanka and southeastern India, experience a rainy winter monsoon as well as a rainy summer monsoon. In their case, the winter monsoon winds that come down from the north have a chance to pick up moisture from the Bay of Bengal before depositing it on their shores.

Early Civilizations

The Indian subcontinent has a long history of human occupation, and is an area where cities independently developed and civilization emerged. The earliest civilization on the subcontinent was the Indus Valley Civilization, in existence from about 3300 BCE to 1500 BCE. This Bronze Age civilization started as a series of small villages that became linked in a wider regional network. Urban centers developed into various religious and trade networks that spanned as far as Central Asia, Southwest Asia, and, perhaps, Egypt. The civilization is known for its planned structures. The cities and villages of the urban phases were planned with major streets going north/south and east/west. It had a system of drains that channeled waste water outside the city. Additionally, this civilization had a homogeneous material culture. Its artifacts of pottery and metallurgy all had a very similar style that was spread over a vast land area, a fact that aided in the recognition of the expanse of the culture.

Invasions by outsiders have the potential effect of bringing with them an influx of new ideas, concepts, and technology. Likewise, the Indus Valley Civilization no doubt had an impact on the region that it encompassed. Little is known of the historical events of earlier times. Some of the evidence we rely on today to discern historical events is gleaned from language, religion, and ethnicity. Significant to South Asia is the presence of Indo-European languages. It is presumed that these languages were brought to the region by immigrants from the west, where these languages were dominant. Aryans from Persia and other cultures might have diffused languages such as Hindi to South Asia, which later may have led to Hindi, for example, becoming the lingua franca of the region.

The northern plains of South Asia, which extend through the Ganges River valley over to the Indus River valley of present-day Pakistan, were fertile grounds for a number of empires that controlled the region throughout history. After the decline of the Indus Valley Civilization, various phases of Iron Age traditions emerged. Most of this Iron Age culture is defined by the presence of iron metallurgy and distinctive characteristics of ceramics.

The Mauryan Empire existed between 322 and 185 BCE and was one of the most extensive and powerful political and military empires in ancient India. This empire was founded by Chandragupta Maurya in 322 BCE, who began to extend his regime westward, easily conquering areas that had been disrupted by the expansion of Alexander the Great’s armies. The Mauryan Empire was prosperous and greatly expanded the region’s trade, agriculture, and economic activities. This empire created a single and efficient system of finance, administration, and security. One of the greatest emperors in the Mauryan dynasty was Ashoka the Great, who ruled over a long period of peace and prosperity. Ashoka embraced Buddhism and focused on peace for much of his rule. He created hospitals and schools and renovated major road systems throughout the empire. His advancement of Buddhist ideals is credited with being the reason most of the population on the island of Sri Lanka is Buddhist to this day.

Islam became a powerful force in South Asia upon its diffusion to the subcontinent. Muslim dynasties or kingdoms that ruled India between 1206 and 1526 are referred to collectively as the Delhi Sultanate. The Delhi Sultanate ended in 1526 when it was absorbed into the expanding Mughal Empire. The Islamic Mughal Empire ruled over much of northern and central India from the 1500s to about the middle of the nineteenth century. After 1725, it began to decline rapidly because of a combination of factors, with European colonialism adding the finishing touch. The Mughal Empire had been religiously tolerant but Muslim oriented. The classic period of this empire began in 1556 and ended in 1707. Many of the monuments we associate with India, including the Taj Mahal, the Red Fort in Lahore, and the Agra Fort, were built during the classical period.

Colonialism in South Asia

The force of colonialism was felt around the world, including in South Asia. South Asia provides an excellent example of colonialism’s role in establishing most of the current political borders in the world. From the sixteenth century onward, ships from colonial Europe began to arrive in South Asia to conduct trade. The British East India Company was chartered in 1600 to trade in Asia and India. They traded in spices, silk, cotton, and other goods. Later, to take advantage of conflicts and bitter rivalries between kingdoms, European powers began to establish colonies. Britain controlled South Asia from 1857 to 1947.

British colonialism in South Asia began in 1857 and lasted until 1947.

Goa is the smallest state in modern-day India. In the sixteenth century, it was first encountered by Portuguese traders, who annexed it shortly after arriving. Goa was a colony of Portugal for the next 450 years. By the mid-1800s, most of the population of the tiny area had been forcibly converted to Christianity. Many of the Hindu traditions, however, survived in the region. Hindu holidays are celebrated among the expatriate community in India. Christian holidays are also celebrated, especially Christmas and Easter. The cathedrals and secular architecture in many of the historic buildings of Goa are European in style, reflecting its Portuguese origins. This architecture is locally termed “Indo-Portuguese.” Goa was one of the longest-held colonial possessions in the world. It was finally annexed to India in 1961.

The British no longer controlled South Asia after 1947. Local resistance and the devastating effects of World War II meant the British Empire could not be controlled as it once was. Great Britain pulled away from empire building to focus on its own redevelopment. Upon the British withdrawal from India, Britain realized the immense cultural differences between the Muslims and Hindus and created political boundaries based on those differences. West Pakistan was carved out of western India; East Pakistan was carved from eastern India. However, the new borders separating Hindu and Muslim majorities ran through population groups, and some of the population now found itself to be on the wrong side of the border. The West Pakistan-India partition grew into a tragic civil war, as Hindus and Muslims struggled to migrate to their country of choice. More than one million people died in the civil war, a war that is still referred to in today’s political dialogue between Pakistan and India. The Sikhs, who are indigenous to the Punjab region in the middle, also suffered greatly. Some people decided not to migrate, which explains why India has the largest Muslim population of any non-Muslim state.

Another civil war would erupt in 1973 between West Pakistan and East Pakistan. When the states were first created in 1947, they operated under the same government despite having no common border and being over nine hundred miles apart and populated by people with no ethnic similarities. The civil war lasted about three months and resulted in the creation of the sovereign countries of Pakistan and Bangladesh (formerly East Pakistan). The name Bangladesh is based on the Bengali ethnicity of most of the people who live there. Both Pakistan and Bangladesh are among the top ten most populous countries in the world.

Language is probably one of the more pervasive ways that Europeans affected South Asia. In modern-day India and Pakistan, English is the language of choice in secondary education (English-medium schools). It is often the language used by the government and military. Unlike many other Asian countries, much of the signage and advertising in Pakistan and India is in English, even in rural areas. Educated people switch back and forth, using English words or entire English sentences during conversation in their native tongue. Some scholars have termed this Hinglish or Urglish as the base languages of northern India and Pakistan are Hindi and Urdu, respectively.

The British game of cricket is an important cultural and national sport within this Asian subcontinent. The constant conflict between the nations of India and Pakistan are reflected in the intense rivalry between their national cricket teams. The Cricket World Cup is held every four years and is awarded by the International Cricket Council. South Asian countries have won the Cricket World Cup three times: India (1983), Pakistan (1992), and Sri Lanka (1996).

Population in South Asia

South Asia has three of the ten most populous countries in the world. India is the second largest in the world, and Pakistan and Bangladesh are numbers five and six, respectively. Large populations are a product of large family sizes and a high fertility rate. The rural population of South Asia has traditionally had large families. Religious traditions do not necessarily support anything other than a high fertility rate. On the other hand, the least densely populated country in South Asia is the Kingdom of Bhutan. Bhutan has a population density of only fifty people per square mile. Bhutan is mountainous with little arable land. More than a third of the people in Bhutan live in an urban setting. Population overgrowth for the realm is a serious concern. An increase in population requires additional natural resources, energy, and food production, all of which are in short supply in many areas.

South Asia’s growing population has placed exceedingly high demands on agricultural production. The amount of area available for food production divided by the population may be a more helpful indicator of population distribution than total population density. For example, large portions of Pakistan are deserts and mountains that do not provide arable land for food production. India has the Thar Desert and the northern mountains. Nepal has the Himalayas. The small country of the Maldives, with its many islands, has almost no arable land. The number of people per square mile of arable land, which is called the physiologic density, can be an important indicator of a country’s status. Total population densities are high in South Asia, but the physiologic densities are even more astounding. In Bangladesh, for example, more than five thousand people depend on every square mile of arable land. In Sri Lanka the physiologic density reaches to more than 6,000 people per square mile, and in Pakistan it is more than 2,400. The data are averages, which indicate that the population density in the fertile river valleys and the agricultural lowlands might be even higher.

Urban areas of South Asia are expanding rapidly.

The population of South Asia is relatively young. In Pakistan about 35 percent of the population is under the age of fifteen, while about 30 percent of India’s almost 1.2 billion people are under the age of fifteen. Many of these young people live in rural areas, as most of the people of South Asia work in agriculture and live a subsistence lifestyle. As the population increases, the cities are swelling to accompany the growth in the urban population and the large influx of migrants arriving from rural areas. Rural-to-urban shift is extremely high in South Asia and will continue to fuel the expansion of the urban centers into some of the largest cities on the planet. The rural-to-urban shift that is occurring in South Asia also coincides with an increase in the region’s interaction with the global economy.

The South Asian countries are transitioning through the five stages of the index of economic development. The more rural agricultural regions are in the lower stages of the index. The realm experienced rapid population growth during the latter half of the twentieth century. As death rates declined and family size remained high, the population swiftly increased. India, for example, grew from fewer than four hundred million in 1950 to more than one billion at the turn of the century. The more urbanized areas are transitioning into stage 3 of the index and experiencing significant rural-to-urban shift. Large cities such as Mumbai (Bombay) have sectors that are in the latter stages of the index because of their urbanized work force and higher incomes. Family size is decreasing in the more urbanized areas and in the realm as a whole, and demographers predict that eventually the population will stabilize.

Figure 9.6 Population Growth in India

At the current rates of population growth, the population of South Asia will double in about fifty years. Doubling the population of Bangladesh would be the equivalent of having the entire 2011 population of the United States (more than 313 million people) all living within the borders of the US state of Wisconsin. The general rule of calculating doubling time for a population is to take the number seventy and divide it by the population growth rate. For Bangladesh the doubling time would be 70 ÷ 1.57 = 45 years. The doubling time for a population can help determine the economic prospects of a country or region. South Asia is coming under an increased burden of population growth. If India continues at its current rate of population increase, it will double its population in fifty-two years, to approximately 2.4 billion. Because the region’s rate of growth has been gradually in decline, this doubling time is unlikely. However, without continued attention to how the societies address family planning and birth control, South Asia will likely face serious resource shortages in the future.

Key Takeaways

  • All the South Asian countries border India by either a physical or a marine boundary. The Himalayas form a natural boundary between South Asia and East Asia (China). The realm is surrounded by deserts, the Indian Ocean, and the high Himalayan ranges.
  • The summer monsoon arrives in South Asia in late May or early June and subsides by early October. The rains that accompany the monsoon account for most of the rainfall for South Asia. Water is a primary resource, and the larger river systems are home to large populations.
  • The Indus River Valley was a location of early human civilization. The large empires of the realm gave way to European colonialism. The British dominated the realm for ninety years from 1857 to 1947 and established the main boundaries of the realm.
  • Population growth is a major concern for South Asia. The already enormous populations of South Asia continue to increase, challenging the economic systems and depleting natural resources at an unsustainable rate.
