GEOG101: World Regional Geography

Study this map of South Asia so you are familiar with the locations of the countries and some of the major geographic features.

Watch this video. Figure 8.1 displays many of the features mentioned in the reading and video. The Thar Desert, also known as the Great Indian Desert, is not labeled on the map. It extends from northwest India into eastern Pakistan.

You can easily identify the Thar Desert and Deccan Plateau, the arid and semi-arid areas of the region, in Figure 8.2, the climate map that is also displayed in the video. Remember that Afghanistan is not part of South Asia, although it is included in the climate map.

This map shows the Köppen climate classifications in South Asia and Afghanistan.

The Himalayan Mountains were a product of the collision of the Indian and Eurasian plates. This collision of the two tectonic plates continues to produce destructive forces in the form of earthquakes. Nepal was struck particularly hard on April 25, 2015 – the Gorkha earthquake (magnitude 7.8) was the strongest earthquake to strike Nepal since 1934. See Figure 8.3 for the location of the earthquake's epicenter, about 80 km northwest of the capital, Kathmandu.

The Gorkha earthquake triggered landslides and avalanches, killing nearly 9,000 people and injuring almost 18,000 others. More than 750,000 houses were destroyed or damaged. The village of Langtang, shown in Figure 8.3, was almost completely destroyed when a landslide deposited an estimated 40 million tons of rock and ice onto the village. Many of the dead and injured lived in Langtang or were tourists visiting the Langtang National Park.

The earthquake originated 8.2 km below the surface of the Earth on or near the main thrust interface between the Indian and Eurasia plates. Figure 8.4 illustrates the convergence of these two plates.

On May 12, 2015, an aftershock with a magnitude of 7.3, shown in Figure 8.3, triggered an avalanche that killed 20 and injured 120 at the Mount Everest Base Camp. People were killed and injured in China, Bangladesh, and India.

The monsoon weather pattern is another characteristic of this region that impacts the human landscape. Monsoons are seasonal winds that bring heavy rains in the summer but leave the landmass dry in the winter. In South Asia, when the Intertropical Convergence Zone (ITCZ) migrates north in the summer, moisture-laden air from the Indian Ocean is drawn to the warmer landmass. Thus, these monsoonal winds bring heavy rains in the summer. When the ITCZ migrates south in the winter, the winds reverse and blow from the cooler landmass to the warmer ocean.

Monsoons bring heavy rains that cause flooding. The people who live along rivers to access the water and fertile soil are especially vulnerable. Every year, monsoonal rains and the ensuing floods displace people, destroy infrastructure, and increase the prevalence of water-borne diseases. If drought conditions precede the rainfall, flooding occurs sooner because the rain runs off the dry, crusty surface directly into streams and rivers. When soils are dry, it takes longer for water to infiltrate the surface.

After this discussion of the rainfall and monsoon winds, it seems ironic that access to fresh water is a problem in some parts of South Asia. For example, urban planners warn that central Pakistan and northwest India are on the brink of a groundwater crisis due to rising population, the effects of climate change, and the natural lag in groundwater response to management interventions.

Central Pakistan's groundwater also suffers from arsenic contamination. Water evaporates quickly in hot, arid climates such as those in the Indus Plain, creating conditions that increase arsenic levels in the groundwater.

Read this article to learn more about groundwater conditions in central Pakistan and its neighbor, northwest India. The conditions in central Pakistan and northwest India have not changed since it was published in 2017. Indeed, these groundwater systems are among the most heavily exploited in the world.

Figure 8.6 shows how groundwater levels on March 15, 2021, compared to long-term records for the month of March. Blue areas had more abundant water than usual, and orange and red areas had less. The darkest reds represent dry conditions that should occur only two percent of the time (about once every 50 years). Northern India and parts of Pakistan have conditions that should occur only two percent of the time. There are efforts underway to use data like this to better manage water resources in the region.

The rising sea level is threatening the island country of Maldives. Alex Arnall, the environmental geographer, has found that governments must address issues associated with coastal development if places like the Maldives are to survive. Read this article to learn more about these environmental challenges. We will also examine how island countries in Oceania are also threatened by rising sea levels in Unit 10.

Read this text which introduces the human geography of South Asia, including the evolving patterns of human settlement, the effects of colonization of the region, and the ethnic, linguistic, and religious characteristics that emerged over time.

Finlayson briefly describes some of South Asia's urban and economic issues, including megacities, outsourcing, and economic development. We will consider these and other issues in the next section.

Buddhism, Hinduism, and Islam are the dominant religions in South Asia. Hinduism and Buddhism, in addition to Sikhism and Jainism, originated in South Asia. Hinduism and Buddhism both originated in northern India and are the world's third- and fourth-largest religions, respectively.

Hindus and Buddhists use some of the same basic vocabularies and incorporate similar symbolism and practices. However, there are substantial differences. For example, Hindus do not have a single founder; they worship deities and have the concept of a soul (Buddhists do not). Buddhists show reverence and devotion to the Buddha rather than recognize a god. They also renounce the caste system.

Different variations of Buddhism developed as it spread from northern India according to geography, the teachings communities followed, and how monks were ordained. The northern branch, Vajrayana Buddhism, is often called Tibetan Buddhism. The southern branch, Theravada Buddhism, is sometimes called Southern Buddhism. The eastern branch, Mahayana Buddhism, is often referred to as East Asian Buddhism.

Read this text. Notice that Figure 8.8 illustrates the distribution of these branches of Buddhism. Regardless of the focus of each branch, all hold to the Four Noble Truths and the Eightfold Path taught by the Buddha.

Watch this video.

Watch this video where Devdutt Pattanaik, a mythologist, contrasts Indian and Western belief systems, including perspectives of living one life versus infinite lives. He explains how components of Hinduism have influenced business practices in India. He has also created a strategy for applying aspects of cultural sensitivity to avoid and mitigate conflict.

Pattanaik reminds us that imperial powers can change boundaries and official languages, but they can seldom dominate the culture. However, colonies often embrace some cultural changes. For example, cricket has become a national pastime in South Asia since British sailors brought it to India during the 18th century.

The British Empire did influence the human landscape of South Asia, although its culture remained largely intact. Britain began establishing colonies in 1857 through the trade activities of the British East India Company. British ruled this region for nearly 100 years. Figure 8.7 shows the extent of Britain's Indian Empire. Note that this map includes the country of Burma (now Myanmar), which we will study in Unit 9.

After this partition, disputes arose among the Hindus who happened to live in the area now designated as Pakistan (which was primarily Muslim) and the Muslims who lived in what was now India (primarily Hindu). War erupted when the new governments in Pakistan and India were unable to manage the mass migration of people who wanted to move to their country of choice.

Relations between West and East Pakistan were strained from the beginning – their shared religion (Islam) was unable to bridge their cultural differences. The population in East Pakistan is predominantly Bengali. The people of Bengal, the region around the Bay of Bengal, have their own language and cultural designation. The people who lived in East Pakistan felt further alienated when Karachi in West Pakistan was chosen as the first capital of Pakistan, and Urdu became the national language.

Bengali nationalism peaked after the catastrophic 1970 Bhola cyclone, which killed 500,000 people when it struck East Pakistan. The population resented the inadequate support they received from the federal government in response to the disaster. An ensuing war for independence resulted in the new sovereign state of Bangladesh in December of 1971. The previously western portion of Pakistan became the country we call Pakistan today.

The British colonists left several legacies in this region. The official languages in India are Hindu and English, and in Pakistan, they are Urdu and English. The British also created a vast railroad system and a series of port cities to transport the resources they extracted and ship them to Great Britain. However, they did not build this system to serve the Indian population. It consisted of individual lines that linked the resource depots located in the country's interior to the coast. It was not an integrated network to help the Indians travel from city to city.

The British East India Company developed three major port cities along the Indian coast to send and receive goods by ship. Bombay (now Mumbai) on the west coast provided access to the Arabian Sea. Madras (now Chennai) on the southeast coast provided access to the lower Bay of Bengal, and Calcutta (now Kolkata) on the lower Ganges Delta along the northeast coast provided access to the upper Bay of Bengal.

The British moved the capital city of India from Kolkata to New Delhi in 1911. New Delhi's central location made it easier to administer the entire country. Kolkata also harbored anti-colonial sentiment and was the center of India's nationalist movements. Several assassinations of British officials took place in Kolkata. See Figure 8.1 for the locations of these cities.

The island country of Sri Lanka was also part of the British Empire, and its ethnic groups continue to be deeply divided, but the map in Figure 8.7 is not shaded to reflect its colonial status. Finlayson refers to this communal conflict at the end of Section 8.5. The population is temporarily unified as it responds to the economic crisis the COVID-19 pandemic caused and the war in Ukraine, which caused global food and energy prices to spike.

Read this article for more on the competing ethnic groups and the effects British imperialism has had on the conflict. Figure 8.9 shows the distribution of languages and religious groups by district in Sri Lanka. The majority Sinhalese clearly dominate the island, while the Tamils generally occupy the northern and eastern periphery. The Sinhalese are an Indo-Aryan group, whereas the Tamils are a Dravidian ethnolinguistic group. Note that Figure 8.7 of in the article in section 8.3, Cultural Groups in South Asia, shows a group of Tamil speakers in southern India. The orange polygon of Indian Tamils in south-central Sri Lanka coincides with Mount Pidurutalagalahe, a summit of 2,525 m. Muslims are clearly a minority group.

This map shows the distribution of languages and religious groups in Sri Lanka.

Watch this video. Note that Rueschhoff corrects a statement he makes in the video that Bangladesh is the most densely populated country in the world. He writes that the population density in Bangladesh is roughly 2,900 per square mile, making it the tenth most densely-populated country (seventh by some measures).

Finlayson and Rueschhoff mention the Green Revolution. Watch this video to learn more about the Green Revolution and its impact on this region and others.

Watch this video for more on population pyramids.

Consider the 2022 population pyramid for Bhutan in Figure 8.10 to make sure you interpret a population pyramid. Notice how there are more males than females and that fertility rates are decreasing. Recall that Finlayson cites a preference for males in this region.

While poverty characterizes much of the region of South Asia, remember Figure 4.13 World Map of Gini Coefficients by Country in Section 4.5 and Figure 4.16 Total Gross Domestic (GDP) in 2022 in Section 4.6. We find that Gini coefficients and GDP are generally moderate for South Asia. This is a useful reminder that single measures do not tell the whole story.

Read this article where Tista Kundu, an economist, writes that many Indians experience inequality due to its prevailing caste system. Kundu cites World Inequality Report 2022, another method to measure inequality that does not use Gini coefficients in which India scores even worse.

Note that gross domestic product (GDP) is not one of those measures – GDP only tells us only about overall production, not value or well-being. In 2021, Japan had the third-highest GDP in the world, but it had a low inequality rating.

Read this article to learn how economists in Bhutan created a rating system called gross national happiness (GNH) as a way to mitigate its isolation from the global economy. The GNH focuses on defining what constitutes happiness rather than how to achieve it. While GNH does not tell the whole story, there is some value to looking beyond GDP.

For example, in 1972, Bhutan's legislators began to take good governance, sustainable development, preservation and promotion of culture, and environmental conservation into account during their policymaking process.
