High-Mountain Asia (HMA) is a high-elevation [1] geographic region in central-south Asia that includes numerous cordillera and highland systems around the Tibetan Plateau, encompassing regions of East, Southeast, South and Central Asia. The region was orogenically formed by the continental collision of the Indian Plate into (and underneath) the Eurasian Plate.
According to NASA, the region is the "world's largest reservoir of perennial glaciers and snow outside of the Earth's polar ice sheets", [2] and has been nicknamed the "Third Pole". Their meltwaters and runoffs form the headwaters of river systems that support the drinking water and food production of nearly 3 billion people, and hydrological and climate changes in the mountains affect "ecosystem services, agriculture, energy and livelihood" [3] for all the surrounding areas. [4] [5] NASA has a High Mountain Asia Team (HiMAT) to study the region. [3]
Recently, in a 2020 study the term High Asia or High Mountain Asia was used metaphorically to categorise Kashmir, Hazara, Nuristan, Laghman, Azad Kashmir, Jammu, Himachal Pradesh, Ladakh, Gilgit Baltistan, Chitral, Western Tibet, Western Xinjiang, Badakhshan, Gorno Badakhshan, Fergana, Osh and Turkistan Region. These rich resource areas are surrounded by the five major mountainous systems of Tien Shan, Pamirs, Karakoram, Hindu Kush and Western Himalayas and the three main river systems of Amu Darya, Syr Darya and Indus. The work further highlighted the role of United States, China, Russia, UK, India, Pakistan, Afghanistan, Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, Turkey, Iran and other players involved in The New Great Game over who will dominate High Asia in the 21st century.

High-Mountain Asia is centered around Tibetan Plateau (a.k.a. the "Roof of the World"), and extends to the surrounding regions as numerous mountain ranges:
These mountain range networks contains all 14 peaks above 8,000 m (26,000 ft) and all of the peaks above 7,200 m (23,600 ft), and expand across the mountainous Chinese provinces of Tibet, Xinjiang, Sichuan and Yunnan (including the flat and depressed Tarim Basin in southern Xinjiang, which contains China's largest desert, the Taklamakan), [8] northern Myanmar, the Himalayan nations of Nepal and Bhutan as well as north/northwestern Pakistan and northeastern India, and most of the southeastern Central Asian nations of Kyrgyzstan, Tajikistan and Afghanistan. Their rain shadows are partly responsible for the cold arid climate in parts of Central Asia and the Mongolian Plateau.
The Amu Darya, also called the Amu, the Amo, and historically the Oxus, is a major river in Central Asia, which flows through Tajikistan, Turkmenistan, Uzbekistan and Afghanistan. Rising in the Pamir Mountains, north of the Hindu Kush, the Amu Darya is formed by the confluence of the Vakhsh and Panj rivers, in the Tigrovaya Balka Nature Reserve on the border between Afghanistan and Tajikistan, and flows from there north-westwards into the southern remnants of the Aral Sea. In its upper course, the river forms part of Afghanistan's northern border with Tajikistan, Uzbekistan, and Turkmenistan. In ancient history, the river was regarded as the boundary of Greater Iran with Turan, which roughly corresponded to present-day Central Asia. The Amu Darya has a flow of about 70 cubic kilometres per year on average.
China has great physical diversity. The eastern plains and southern coasts of the country consist of fertile lowlands and foothills. They are the location of most of China's agricultural output and human population. The southern areas of the country consist of hilly and mountainous terrain. The west and north of the country are dominated by sunken basins, rolling plateaus, and towering massifs. It contains part of the highest tableland on earth, the Tibetan Plateau, and has much lower agricultural potential and population.
Tajikistan is nestled between Kyrgyzstan and Uzbekistan to the north and west, China to the east, and Afghanistan to the south. Mountains cover 93 percent of Tajikistan's surface area. The two principal ranges, the Pamir Mountains and the Alay Mountains, give rise to many glacier-fed streams and rivers, which have been used to irrigate farmlands since ancient times. Central Asia's other major mountain range, the Tian Shan, skirts northern Tajikistan. Mountainous terrain separates Tajikistan's two population centers, which are in the lowlands of the southern and northern sections of the country. Especially in areas of intensive agricultural and industrial activity, the Soviet Union's natural resource utilization policies left independent Tajikistan with a legacy of environmental problems.
The Himalayas, or Himalaya is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the Earth's highest peaks, including the highest, Mount Everest. More than 100 peaks exceeding elevations of 7,200 m (23,600 ft) above sea level lie in the Himalayas.
The Hindu Kush is an 800-kilometre-long (500 mi) mountain range on the Iranian Plateau in Central and South Asia to the west of the Himalayas. It stretches from central and eastern Afghanistan into northwestern Pakistan and far southeastern Tajikistan. The range forms the western section of the Hindu Kush Himalayan Region (HKH); to the north, near its northeastern end, the Hindu Kush buttresses the Pamir Mountains near the point where the borders of China, Pakistan and Afghanistan meet, after which it runs southwest through Pakistan and into Afghanistan near their border.
The Tian Shan, also known as the Tengri Tagh or Tengir-Too, meaning the "Mountains of God/Heaven", is a large system of mountain ranges in Central Asia. The highest peak is Jengish Chokusu at 7,439 metres (24,406 ft) high. Its lowest point is the Turpan Depression, which is 154 m (505 ft) below sea level.
The Karakoram is a mountain range in the Kashmir region spanning the border of Pakistan, China, and India, with the northwestern extremity of the range extending to Afghanistan and Tajikistan. Most of the Karakoram mountain range falls under the jurisdiction of Gilgit-Baltistan, which is controlled by Pakistan. Its highest peak, K2, is located in Gilgit-Baltistan, Pakistan. It begins in the Wakhan Corridor (Afghanistan) in the west, encompasses the majority of Gilgit-Baltistan, Pakistan and extends into Ladakh and Aksai Chin.
The Wakhan Corridor is a narrow strip of territory in the Badakhshan province of Afghanistan. This corridor stretches eastward, connecting Afghanistan to Xinjiang, China. It also separates the Gorno-Badakhshan Autonomous Region of Tajikistan in the north from the Khyber Pakhtunkhwa and Gilgit-Baltistan regions of Pakistan in the south, the latter of which is also part of the disputed region of Kashmir. This high mountain valley serves as the source of both the Panj and Pamir rivers, which converge to form the larger Amu River. For countless centuries, a vital trade route has traversed this valley, facilitating the movement of travelers to and from East, South, and Central Asia.
The Roof of the World or Top of the World is a metaphoric epithet or phrase used to describe the highest region in the world, also known as High Asia. The term usually refers to the mountainous interior of Asia, including the Pamirs, the Himalayas, the Tibetan Plateau, the Hindu Kush, the Tian Shan, and the Altai Mountains.
The Pamir Mountains are a range of mountains between Central Asia and South Asia. They are located at a junction with other notable mountains, namely the Tian Shan, Karakoram, Kunlun, Hindu Kush and the Himalaya mountain ranges. They are among the world's highest mountains.
The Tibetan Plateau, also known as Qinghai–Tibet Plateau and Qing–Zang Plateau, is a vast elevated plateau located at the intersection of Central, South, and East Asia covering most of the Tibet Autonomous Region, most of Qinghai, western half of Sichuan, Southern Gansu provinces in Western China, southern Xinjiang, Bhutan, the Indian regions of Ladakh and Lahaul and Spiti as well as Gilgit-Baltistan in Pakistan, northwestern Nepal, eastern Tajikistan and southern Kyrgyzstan. It stretches approximately 1,000 kilometres (620 mi) north to south and 2,500 kilometres (1,600 mi) east to west. It is the world's highest and largest plateau above sea level, with an area of 2,500,000 square kilometres (970,000 sq mi). With an average elevation exceeding 4,500 metres (14,800 ft) and being surrounded by imposing mountain ranges that harbor the world's two highest summits, Mount Everest and K2, the Tibetan Plateau is often referred to as "the Roof of the World".
Wakhan, or "the Wakhan", is a rugged, mountainous part of the Pamir, Hindu Kush and Karakoram regions of Afghanistan. Wakhan District is a district in Badakshan Province.
Northern Pakistan is a tourism region in northern and north-western parts of Pakistan, comprising the administrative units of Gilgit-Baltistan, Azad Kashmir, Khyber Pakhtunkhwa, Islamabad Capital Territory and the Rawalpindi Division in Punjab. The first two territories are a part of the wider Kashmir region. It is a mountainous region straddling the Himalayas, Karakoram and the Hindu Kush mountain ranges, containing many of the highest peaks in the world and some of the longest glaciers outside polar regions. Northern Pakistan accounts for a high level of Pakistan's tourism industry.
Muztagh Ata or Muztagata is the second highest of the mountains which form the northern edge of the Tibetan Plateau in China. It is sometimes regarded as being part of the Kunlun Mountains, although physically it is more closely connected to the Pamirs. It is also one of the relatively easier 7,000 m peaks in the world to climb, due to its gentle western slope and the comparatively drier weather of Xinjiang, though a thorough acclimatization period and a very strong physical condition are crucial for success.
Taghdumbash Pamir or Taxkorgan Nature Reserve is a pamir or high valley in the south west of Tashkurgan Tajik Autonomous County, in Xinjiang, China. It lies to the west of the Karakoram Highway. It is inhabited by Wakhi, Kirghiz and Sarikolis animal herders, who graze yaks and other animals on the grasslands of the Pamir.
The Karakoram fault is an oblique-slip fault system in the Himalayan region across India and Asia. The slip along the fault accommodates radial expansion of the Himalayan arc, northward indentation of the Pamir Mountains, and eastward lateral extrusion of the Tibetan plateau. Current plate motions suggest that the convergence between the Indian Plate and the Eurasian Plate is around 44±5 mm per year in the western Himalaya-Pamir region and approximately 50±2 mm per year in the eastern Himalayan region.
The Pamir alpine desert and tundra ecoregion covers the high plateau of the Pamir Mountains, at the central meeting of the great mountain ranges of Central Asia: Himalaya, Karakoram, Hindu Kush, Kunlun, and Tian Shan. It is a region of relatively high biodiversity due to its central location and high elevation differentials, but it also acts as a barrier between the climate and habitats of north and south Asia.
