In South Asia, Nepal is landscaped and China is in the North; and India is in the South, East, and Western regions. The country covers a total area of 147,516 square kilometers and covers an area of 28°N to 84°E. Nepal falls north of the Tropic of Cancer in the temperate area. It is approximately 800 km from east to west, while only 150 to 250 km from north to south. Nepal has extensive water systems that drain into India south. The region of the Himalaya region, the middle hill region, and the Tari region can be divided into three main geographic regions. Mt. Everest (8,848 m) is the highest point in the country, while the lower point in the KechanaKalan plains of Tarai in Jhapa (60 m).
1) The Himalayan Region:
Almost 16% of Nepal's total land area is covered by the Himalayas. The mountainous region or Parbat begins at 3000m high ridges which leads to mountain pastures and treelines limited to 4000m, with snow lines starting from 5000m. The Everest Mountains (8848m), Kanchenjunga (8586m), Lhotse (8516m), Makalu (8463m), Cho Oyu (8201m), Dhaulagiri (8167m), Manaslu (8163m), and Annapurna have the highest eight out of fourteen mountains over 8000 m in Nepal (8091m). Sites above 3000m like the Mustang and the Dolpo are cold, hard-ground deserts with Tibetan plateau similarities. The rivers Mahakali, Karnali, Narayani, and Koshi originated in the Himalayas, most of the rivers seen through entire Nepal.
The cold, hard climate of this region and the infertile soil are the main reasons for its sparse populations. The Himalayas do not continue over Nepal, unlike the Mahabharata range. In contrast, there is a sporadic propagation of 20 sub-brands of which are the Kanchenjunga mountains along the Sikkim border, the MahalangurHimal in the vicinity of Mt. Everest (NW Kathmandu), Annapurna and Manaslu (NW Pokhara), in the far west Dhaulagiri and the far west GuransHimal.
2) Trans-Himalaya Region:
The north of the highest region lies a waterfront dividing Brahmaputra (known as Yarlung in Tibetan) and the Ganges system. The Himalayan sunshine is crossed by Alpine and subalpine valleys such as Humla, Jumla, Dolpo, Mustang, Manang, or Khumbu. Some of these places were more accessible in Tibet than from Nepal, with Bhotiyas and Sherpa's migration to the hegemony of China on Tibet high. Thus, Tibetan influences in the culture and lifestyle are high in these places. In this region, settlements can be seen at an altitude of 4500 meters. Farming Yak and its products such as hard cheese, yak ghee, or dairy are known for Bhotiyas. They use low-tolerance food crops such as millets, barley, pumpkin, and buckwheat, which provide a year-round food supply.
3) The Hilly Region:
The Hilly region accounts for approximately 65% of Nepal's total area. It begins at Mahabharata, where a failure system known as the Main Boundry Thrust creates a climb from 1000 meters to 15000m in height to a crest of 1500m to 2700m in length. The steep South slopes are almost unusual and thus provide the region of Hilly and Terai with a buffer between language and culture. The Mid-Hill region, which overcomes the challenges of the tough and unforgiving Himalayas, is a bit more populous compared with the Himalayan region. In Hilly, ethnic groups such as Gurung, Magar, Newar, Brahmin, and Chettris are most populated. There are also the Tibeto-Burma languages and dialect of other indigenous ethnic groups, commonly named JanaJati in Nepal.
Subtropical fruits are cultivated as cash crops due to the moderate temperature. Marijuana was also grown to be hashish processed until production was interfered with and the government ultimately illegalized it in 1976. This region depends mainly on agriculture (although, since the abundance of pastures, it was not able to keep pace with national requirements) and animal husbandry.
4)TheTerai or plain region:
Terai is a lowland that accounts for 17% of Nepal's entire territory. The region of Terai is between 26 km and 32 km in width and also between 60 m and 305 m in altitudes. It is a large area of leveled land stretching beyond the Mahakali River to the east of Nepal and west of the Mechi River In its culture, traditions, and languages, and dialects, Terai shares the border of India, and its influences can be seen. Maithili, Bhojpuri, and Tharu, Nepali the official language, are the most common local languages. The Himalayas and Hilly regions are the most populated region because they are easy to live in. It's a haven for agriculture because of the flat fertile lands and tropical climate. Here in this region, most of the nation's food supply is made. This region supports mainly the subtropical forest with hard stems, wide leaves, and evergreen high trees.
In terms of infrastructural advances, Terai is much more developed than others. For every infrastructural development, easy, mixable land is relatively easier than the steep areas of Himalaya and Hilly. Terai is densely populated because of this and other combined factors. The Terai population is 50.3% of Nepal, with the population density being 392 persons/km2, of 2,64,94,504. Terai population.
