Name

The earliest known usage of the Persian name ''Hindu Kush'' occurs on a map published about 1000 CE.Fosco Maraini et al.

Some modern scholars remove the space and refer to the mountain range as ''Hindukush''.


Etymology

''Hindu Kush'' is generally translated as "Killer of

Encyclopædia Iranica
Several other theories have been propounded as to the origins of the name. According to Nigel Allan, the term ''Hindu Kush'' has two alternate meanings i.e. 'sparkling snows of India' and 'mountains of India', with ''Kush'' possibly being a soft variant of the Persian ''Kuh'' ('mountain'). Allan states that Hindu Kush was the frontier boundary to Arab geographers. Yet others suggest that the name may be derived from ancient

Peaks

Many peaks of the range are between , and some are much higher, with an average peak height of . The mountains of the Hindu Kush range diminish in height as they stretch westward. Near Kabul, in the west, they attain heights of ; in the east they extend from .


Passes

Melt water from snow and ice feeds major river systems in Central Asia: the Amu Darya, Helmand River (which is a major source of water for the Sistan Basin in southern Afghanistan and Iran), and the Kabul Riverthe last of which is a major tributary of the Indus River. Smaller rivers with headwaters in the range include the Khash, the Farah and the Arashkan (Harut) rivers. The basins of these rivers serve the ecology and economy of the region, but the water flow in these rivers greatly fluctuates, and reliance on these has been a historical problem with extended droughts being commonplace. The eastern end of the range, with the highest peaks, high snow accumulation allows to long-term water storage.

In 2000, 2005, 2010, and 2015, grassland covered 37.2%, 37.6%, 38.7%, and 38.23%, respectively, of the total area of the HKH region. During the same years, the second dominant land cover was barren areas, including bare soil and bare rock. In 2000, 2005, 2010, and 2015, bare soil and bare rock covered 32.1, 31.37, 30.35, and 30.69%. The cropland cover in 2000 was about 5.1% and about 5.41% in 2015. Snow and glacier areas covered about 4% of the high-elevation section in 2018, while waterbodies and riverbeds/channels together accounted for 2%. The weather conditions also have an impact on the land cover patterns across the regions. In the HKH, forest cover is mostly distributed in the south and south-eastern areas, where precipitation is more; the grasslands are mostly distributed in the north and north-western parts, while cropland is mostly found in the southern part of the region.

came to power in 998 CE, in Ghazna, Afghanistan, south of Kabul and the Hindu Kush range. He began a military campaign that rapidly brought both sides of the Hindu Kush range under his rule. From his mountainous Afghani base, he systematically raided and plundered kingdoms in north India from east of the Indus river to west of Yamuna river seventeen times between 997 and 1030. Mahmud of Ghazni raided the treasuries of kingdoms, sacked cities, and destroyed Hindu temples, with each campaign starting every spring, but he and his army returned to Ghazni and the Hindu Kush base before monsoons arrived in the northwestern part of the subcontinent. He retracted each time, only extending Islamic rule into western Punjab. In 1017, the Iranian Islamic historian Al-Biruni was deported after a war that Mahmud of Ghazni won,Al-Biruni

to the northwest Indian subcontinent under Mahmud's rule. Al Biruni stayed in the region for about fifteen years, learnt Sanskrit, and translated many Indian texts, and wrote about Indian society, culture, sciences, and religion in Persian and Arabic. He stayed for some time in the Hindu Kush region, particularly near Kabul. In 1019, he recorded and described a solar eclipse in what is the modern era Laghman Province of Afghanistan through which Hindu Kush pass. Al Biruni also wrote about early history of the Hindu Kush region and Kabul kings, who ruled the region long before he arrived, but this history is inconsistent with other records available from that era. Al Biruni was supported by Sultan Mahmud. Al Biruni found it difficult to get access to Indian literature locally in the Hindu Kush area, and to explain this he wrote, "Mahmud utterly ruined the prosperity of the country, and performed wonderful exploits by which the Hindus became the atoms scattered in all directions, and like a tale of old in the mouth of the people. (...) This is the reason, too, why Hindu sciences have retired far from those parts of the country conquered by us, and have fled to places which our hand cannot yet reach, to Kashmir, Benares and other places".

history. The Hindu Kush mountain passes connected the slave markets of Central Asia with slaves seized in South Asia.Scott C. Levi (2002), ''Hindus beyond the Hindu Kush: Indians in the Central Asian Slave Trade'', Journal of the Royal Asiatic Society, Cambridge University Press, Volume 12, Number 3 (Nov. 2002), pages 277–288 The seizure and transportation of slaves from the Indian subcontinent became intense in and after the 8th century CE, with evidence suggesting that the slave transport involved "hundreds of thousands" of slaves from India in different periods of Islamic rule era. According to John Coatsworth and others, the slave trading operations during the pre-Akbar Mughal and Delhi Sultanate era "sent thousands of Hindus every year north to Central Asia to pay for horses and other goods". However, the interaction between Central Asia and South Asia through the Hindu Kush was not limited to slavery, it included trading in food, goods, horses and weapons. The practice of raiding tribes, hunting, and kidnapping people for slave trading continued through the 19th century, at an extensive scale, around the Hindu Kush. According to a British Anti-Slavery Society report of 1874, the governor of Faizabad, Mir Ghulam Bey, kept 8,000 horses and cavalrymen who routinely captured non-Muslims as well as Shia Muslims as slaves. Others alleged to be involved in the slave trade were feudal lords such as Ameer Sheer Ali. The isolated communities in the Hindu Kush were one of the targets of these slave-hunting expeditions.

Climate change

The 2019 Hindu Kush Himalaya Assessment concluded that between 1901 to 2014, the Hindu Kush Himalaya (or HKH) region had already experienced warming of 0.1 °C per decade, with the warming rate accelerating to 0.2 °C per decade over the past 50 years.Over the past 50 years, the frequency of warm days and nights had also increased by 1.2 days and 1.7 nights per decade, while the frequency of ''extreme'' warm days and nights had increased by 1.26 days and 2.54 nights per decade. There was also a corresponding decline of 0.5 cold days, 0.85 extreme cold days, 1 cold night, and 2.4 extreme cold nights per decade. The length of the

goal of 1.5 °C of global warming is not exceeded, warming in the HKH will be at least 0.3 °C higher, and at least 0.7 °C higher in the hotspots of northwest Himalaya and Karakoram. If the Paris Agreement goals are broken, then the region is expected to warm by 1.7–2.4 °C in the near future (2036–2065) and by 2.2–3.3 °C (2066–2095) near the end of the century under the "intermediate" Representative Concentration Pathway 4.5 (RCP4.5). Under the high-warming RCP8.5 scenario where the annual emissions continue to increase for the rest of the century, the expected regional warming is 2.3–3.2 °C and 4.2–6.5 °C, respectively. Under all scenarios, winters will warm more than the summers, and the Tibetan Plateau, the central Himalayan Range, and the Karakoram will continue to warm more than the rest of the region.

precipitation in the region will increase by 4–12% in the near future and by 4–25% in the long term. There has also been modelling of the changes in snow cover, but it is limited to the end of century under the RCP 8.5 scenario: it projects declines of 30–50% in the Indus Basin, 50–60% in the Ganges basin, and 50–70% in the Brahmaputra Basin, as the snowline elevation in these regions will rise by between 4.4 and 10.0 m/yr. There has been more extensive modelling of glacier trends: it is projected that one third of all glaciers in the extended HKH region will be lost by 2100 even if the warming is limited to 1.5 °C (with over half of that loss in the Eastern Himalaya region), while RCP 4.5 and RCP 8.5 are likely to lead to the losses of 50% and >67% of the region's glaciers over the same timeframe. Glacier melt is projected to accelerate regional river flows until the amount of meltwater peaks around 2060, going into an irreversible decline afterwards. Since precipitation will continue to increase even as the glacier meltwater contribution declines, annual river flows are only expected to diminish in the western basins where contribution from the monsoon is low: however,

generation would still have to adjust to greater interannual variability and lower pre-monsoon flows in all of the region's rivers.


Future development and adaptation

A range of adaptation efforts are already undertaken across the HKH region: however, they suffer from underinvestment and insufficient coordination between the various state, institutional and other non-state efforts, and need to be "urgently" strengthened in order to be commensurate with the challenges ahead. The 2019 Hindu Kush Himalaya Assessment outlined three main "storylines" for the region between now and 2080: "business-as-usual" (or "muddling through"), with no significant change from the current trends and development/adaptation initiatives proceeding as they do now; "downhill", where the intensity of global climate change is high, local initiatives fail and regional cooperation breaks down; and "prosperous", where extensive cooperation allows region's communities to weather "moderate" climate change and increase their living standards while also preserving the region's biodiversity. In addition, it described two alternate pathways through which the "prosperous" future can be achieved: the first focuses on top-down, large-scale development and the latter describes a bottom-up, decentralized alternative.
