South Asian Distinctive Features!

South Asia is a distinct and unique physiographic division of the world, located in the Indian and Western regions. The region includes the Indian subcontinent and the Persian Gulf, adjoining areas of Pakistan, Afghanistan, China, and Myanmar. South Asia is one of the most populated regions of the world and has a wide variety of habitats ranging from deserts to tropical rain forests. The region’s geological features are extremely complex, with numerous geologic provinces that include mountains, plateaus, and intermontane platforms.

The geography of the area has remained somewhat constant throughout history. South Asia tends to be hot in the summer only occurring in many later months than North America or Northern Europe who have their summer months earlier in springtime. In terms of rainfall, it is also heavily punctuated with high rainfall when monsoons come from July to September which brings flooding to many regions however when they fail there can be a great amount of famine that occurs in certain regions such as India. Temperatures fall in the winter months between December and February and rise again in the spring and summer months.

During the winter, southern Asia can see snowfall in some of its mountain ranges such as the Himalayas and the Hindu Kush. India is separated from Asia by the world’s highest peak Mount Everest. Geologically, this region was once submerged under an ancient Tethys Ocean but it is currently being torn apart by continental drift which has created a divergent plate boundary on either side of the Indian Plate.

The area of South Asia is about 541,000 square miles while its population according to 2014 estimates is around 1.7 billion people accounting for about one-fifth of the world’s current population making Asia the most populated continent on Earth with roughly 50% more landmass than North America.

The Indian subcontinent is surrounded by water on three sides except for one border which is with China. The Indian ocean forms the southern borders while both the Bay of Bengal and Arabian sea are towards the eastern side. The mainland or Peninsular region has some large river basins such as Ganges, Indus, Godavari, Krishna, Kaveri, and Narmada.

The Himalaya mountain range in northern India forms a physical barrier between India and her neighbors to the north however it can also serve as a geographical boundary line because Tibet lies to its northeast while Nepal lies to its northwest. Likewise, Afghanistan lies to the southwest while Iran sits to the southeast near Pakistan’s Baluchistan province. To make this situation even more complicated there are disputed territories in Kashmir and Jammu.

In terms of climate, this area also varies greatly from the Tropics to arid deserts to alpine conditions with summer monsoons which bring flooding however dry winters. The general terrain is mostly a peneplain descending from the Himalayas in the north down toward peninsular India before leveling out toward its expansive coastal plains where it meets the Bay of Bengal in Bangladesh and Sri Lanka.

The rivers that flow through South Asia are an important feature that creates a well-connected network across the region, especially in areas such as Afghanistan, Nepal, Bangladesh, Pakistan, and Myanmar where there are mountainous barriers to provide water for irrigation purposes but often causes floods during monsoon season. Areas such as Australia have an extensive piped water system but Bangladesh sees about 80 percent of its drinking water is supplied by rivers. However, the Ganges river basin is one of the most densely populated regions on earth because of this practice which has led to mass migration and deforestation problems.

Because of its strong monsoons, South Asia finds itself in cyclone territory when it comes to weather with some areas like India experiencing a considerable amount of tornadoes in both Northern and Eastern parts while Sri Lanka experiences about 2 cyclones per year in the Bay of Bengal during its wet season between October and December. Between June and September Bangladesh also faces tropical systems that can cause flooding when they make landfall.

The Indian subcontinent is home to several nature reserves such as the Sundarbans which is home to the largest subpopulations of Bengal tigers. This area also holds many endangered species such as Asian elephants, Indian rhinoceroses, and Indian sharks.

India is one of the most biodiverse regions on earth having about 7 percent of all mammals, 12 percent of birds, and 6 percent of all reptilian species with life zones ranging from Alpine to Tropical with tropical rainforests in areas like southern India although deforestation rates are high due to increasing populations. The Himalayan mountain range is home to 2/3rds of the world’s glaciers including Mount Everest.

The coastline has coral reefs near Sri Lanka while whales can be spotted at both coasts around India, Bangladesh, and Pakistan where some sea turtles come up to lay eggs on shores while some fish species breed in certain rivers like the Ganges.

Indus river is among the most polluted rivers that flow through South Asia due to rapid industrialization and population growth resulting in poor sewage treatment which has led to toxic algae blooms causing public health problems for both India and Pakistan.

India, Bangladesh, Sri Lanka, Pakistan, Nepal, Bhutan, and the Maldives make up South Asia’s borders with China (part of North East), Myanmar (East), and China (Central).
