110-764: The Vakhsh flows through the Pamirs , passing through very mountainous territory that frequently restricts its flow to narrow channels within deep gorges. Some of the largest glaciers in Tajikistan, including the Fedchenko and Abramov glaciers (the former being the longest glacier in the world outside of the polar regions), drain into the Vakhsh. Its largest tributaries are the Muksu and the Obikhingou  [ de ] ;

220-543: A centrally planned economy in which the different republics supplied resources to each other at different times of the year. During the summer, when river flows were greatest, Tajikistan (located upstream) released water from its reservoirs on the Vakhsh and exported the hydroelectricity to power irrigation pumps downstream, in Uzbekistan and Turkmenistan, along the Amu Darya. In winter, Tajik dams accumulated water, and

330-544: A commercial chain in which raw cotton fibers were (at first) purchased from colonial plantations , processed into cotton cloth in the mills of Lancashire , and then exported on British ships to captive colonial markets in West Africa , India , and China (via Shanghai and Hong Kong). By the 1840s, India was no longer capable of supplying the vast quantities of cotton fibers needed by mechanized British factories, while shipping bulky, low-price cotton from India to Britain

440-734: A deficit spiral that led to the country declaring bankruptcy in 1876, a key factor behind Egypt's occupation by the British Empire in 1882 . During this time, cotton cultivation in the British Empire , especially Australia and India, greatly increased to replace the lost production of the American South. Through tariffs and other restrictions, the British government discouraged the production of cotton cloth in India; rather,

550-616: A farmer who farmed one of the biggest cotton operations. He produced over sixty thousand bales. Cotton remained a key crop in the Southern economy after slavery ended in 1865. Across the South, sharecropping evolved, in which landless farmers worked land owned by others in return for a share of the profits. Some farmers rented the land and bore the production costs themselves. Until mechanical cotton pickers were developed, cotton farmers needed additional labor to hand-pick cotton. Picking cotton

660-531: A find in Ancon, to c.  4200 BC , and was the backbone of the development of coastal cultures such as the Norte Chico , Moche , and Nazca . Cotton was grown upriver, made into nets, and traded with fishing villages along the coast for large supplies of fish. The Spanish who came to Mexico and Peru in the early 16th century found the people growing cotton and wearing clothing made of it. The Greeks and

770-487: A great deal of resources would have been required, likely restricting its cultivation to the elite. In the first to third centuries CE, recovered cotton fragments all began to mirror the same style and production method, as seen from the direction of spun cotton and technique of weaving. Cotton textiles also appear in places of high regard, such as on funerary stelae and statues. During the Han dynasty (207 BC - 220 AD), cotton

880-862: 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 . Much of the Pamir Mountains lie in the Gorno-Badakhshan region of Tajikistan . Spanning the border parts of four countries, to the south, they border the Hindu Kush mountains along Afghanistan 's Wakhan Corridor in Badakhshan Province , Chitral and Gilgit-Baltistan regions of Pakistan . To

990-624: A major source of Tajikistan's industrial output and export revenue. As for cotton, Vakhsh water irrigates much of Tajikistan's crop; about 85% of the water taken from the Vakhsh goes toward irrigation. The leaders of the Soviet Union stressed the importance of developing the country's under-developed regions, such as the Tajik Soviet Socialist Republic (which was the predecessor to modern-day, independent Tajikistan). Not only did Vladimir Lenin ’s ideology identify

1100-422: A new market for British goods, while the capital amassed from Bengal after its 1757 conquest was used to invest in British industries such as textile manufacturing and greatly increase British wealth. British colonization also forced open the large Indian market to British goods, which could be sold in India without tariffs or duties , compared to local Indian producers who were heavily taxed , while raw cotton

1210-501: A new revenue system that was biased in favour of higher value cash crops such as cotton and indigo , providing state incentives to grow cash crops, in addition to rising market demand. The largest manufacturing industry in the Mughal Empire was cotton textile manufacturing , which included the production of piece goods , calicos , and muslins , available unbleached and in a variety of colours. The cotton textile industry

1320-642: A number of non-Russians including Ney Elias , George Littledale , the Earl of Dunmore , Wilhelm Filchner and Lord Curzon who was probably the first to reach the Wakhan source of the Oxus River . In 1891 the Russians informed Francis Younghusband that he was on their territory and later escorted a Lieutenant Davidson out of the area ('Pamir Incident'). In 1892 a battalion of Russians under Mikhail Ionov entered

1430-601: A rise in temperatures from between 1.0-1.2 degrees Celsius between 1940 and 2000, and many glaciers that feed the Vakhsh have retreated, including the Fedchenko , which is melting at a rate of 16–20 meters/year. According to Oxfam International , up to 30% of Tajikistan's glaciers could shrink or disappear completely by 2050. The reduction in river flow could lower the Vakhsh's hydropower production, and harm agriculture dependent on its waters for irrigation. Furthermore, if climate change affects precipitation patterns, it could cause more floods, landslides, and other natural disasters in

1540-468: A rocky plain. A pamir lasts until erosion forms soil and cuts down normal valleys. This type of terrain is found in the east and north of the Wakhan , and the east and south of Gorno-Badakhshan, as opposed to the valleys and gorges of the west. Pamirs are used for summer pasture. The Great Pamir is around Lake Zorkul . The Little Pamir is east of this in the far east of Wakhan. The Taghdumbash Pamir

1650-996: Is between Tashkurgan and the Wakhan west of the Karakoram Highway . The Alichur Pamir is around Yashil Kul on the Gunt River . The Sarez Pamir is around the town of Murghab, Tajikistan . The Khargush Pamir is south of Lake Karakul . There are several others. The Pamir River is in the south-west of the Pamirs. The three highest mountains in the Pamirs core are Ismoil Somoni Peak (known from 1932 to 1962 as Stalin Peak, and from 1962 to 1998 as Communism Peak), 7,495 m (24,590 ft); Ibn Sina Peak (still unofficially known as Lenin Peak), 7,134 m (23,406 ft); and Peak Korzhenevskaya ( Russian : Пик Корженевской , Pik Korzhenevskoi ), 7,105 m (23,310 ft). In

1760-729: Is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable , and durable textile . The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization , as well as fabric remnants dated back to 4200 BC in Peru . Although cultivated since antiquity, it

1870-622: Is ineffective against many cotton pests, such as plant bugs , stink bugs , and aphids ; depending on circumstances it may still be desirable to use insecticides against these. A 2006 study done by Cornell researchers, the Center for Chinese Agricultural Policy and the Chinese Academy of Science on Bt cotton farming in China found that after seven years these secondary pests that were normally controlled by pesticide had increased, necessitating

1980-547: Is located at the confluence of the Vakhsh and the Panj. The catchment area of the Vakhsh is 39,100 km, of which 31,200 km (79.8%) lies within Tajikistan. The river contributes about 25% of the total flow of the Amu Darya, its parent river . Its average discharge is 538 m/s, with an annual discharge of 20.0 km. However, since the Vakhsh is fed mostly by melting snow and glaciers , these flow rates have great seasonal variability between winter and summer. Measurements at

2090-571: Is the domestication of Gossypium hirsutum in Mexico between around 3400 and 2300 BC. During this time, people between the Río Santiago and the Río Balsas grew, spun, wove, dyed, and sewed cotton. What they did not use themselves, they sent to their Aztec rulers as tribute, on the scale of ~116 million pounds (53,000 tonnes) annually. In Peru , cultivation of the indigenous cotton species Gossypium barbadense has been dated, from

2200-519: Is the isolated region's main supply route. The Great Silk Road crossed a number of Pamir Mountain ranges. In December 2009, the New York Times featured articles on the possibilities for tourism in the Pamir area of Tajikistan. 2013 proved to be the most successful year ever for tourism in the region and tourism development continues to be the fastest growing economic sector. Historically,

2310-585: Is written Памир / Цунлин in the Cyrillic alphabet , and in Xiao'erjing it is written پَامِعَر / ڞوْلٍْ . The name "Pamir" is used more commonly in Modern Chinese and loaned as 帕米尔 / 帕米爾 Pàmǐ'ěr . According to Middleton and Thomas, "pamir" is also a geological term. A pamir is a flat plateau or U-shaped valley surrounded by mountains. It forms when a glacier or ice field melts leaving

2420-613: The Baipaza Dam has blocked the river twice (in 1992 and 2002) ever since this dam opened in 1985. Both blockages were immediately blasted to clear the river channel, since they threatened to raise the water level high enough to flood the dam. Such an event could potentially have serious economic consequences by disrupting power generation, stopping production at the Tajik Aluminum Company , and cutting off supplies of drinking and irrigation water for downstream users. In

2530-649: The Deep South . To acknowledge cotton's place in the history and heritage of Texas, the Texas Legislature designated cotton the official "State Fiber and Fabric of Texas" in 1997. China's Chang'e 4 spacecraft took cotton seeds to the Moon's far side . On 15 January 2019, China announced that a cotton seed sprouted, the first "truly otherworldly plant in history". Inside the Von Kármán Crater ,

2640-473: The Delhi Sultanate . During the late medieval period, cotton became known as an imported fiber in northern Europe, without any knowledge of how it was derived, other than that it was a plant. Because Herodotus had written in his Histories , Book III, 106, that in India trees grew in the wild producing wool, it was assumed that the plant was a tree, rather than a shrub. This aspect is retained in

2750-532: The Industrial Revolution in Britain provided a great boost to cotton manufacture, as textiles emerged as Britain's leading export. In 1738, Lewis Paul and John Wyatt , of Birmingham , England, patented the roller spinning machine, as well as the flyer-and-bobbin system for drawing cotton to a more even thickness using two sets of rollers that traveled at different speeds. Later, the invention of

2860-469: The James Hargreaves ' spinning jenny in 1764, Richard Arkwright 's spinning frame in 1769 and Samuel Crompton 's spinning mule in 1775 enabled British spinners to produce cotton yarn at much higher rates. From the late 18th century on, the British city of Manchester acquired the nickname " Cottonopolis " due to the cotton industry's omnipresence within the city, and Manchester's role as

2970-724: The Neolithic site of Mehrgarh , at the foot of the Bolan Pass in ancient India , today in Balochistan Pakistan. Fragments of cotton textiles have been found at Mohenjo-daro and other sites of the Bronze Age Indus Valley civilization , and cotton may have been an important export from it. Cotton bolls discovered in a cave near Tehuacán , Mexico, have been dated to as early as 5500 BC, but this date has been challenged. More securely dated

3080-515: The Nurek Dam indicate that winter flow rates average around 150 m/s, whereas flow rates during the summer months can exceed 1500 m/s – a tenfold increase. The Vakhsh has been intensively developed for human use. Electricity, aluminum, and cotton are the mainstays of Tajikistan's economy, and the Vakhsh is involved with all three of these sectors. Hydroelectricity provides 91% of the country's electricity as of 2005, and 90% of that total comes from

3190-511: The 1840s. Indian cotton textiles, particularly those from Bengal , continued to maintain a competitive advantage up until the 19th century. In order to compete with India, Britain invested in labour-saving technical progress, while implementing protectionist policies such as bans and tariffs to restrict Indian imports. At the same time, the East India Company's rule in India contributed to its deindustrialization , opening up

3300-504: The 19th century. India's cotton-processing sector changed during EIC expansion in India in the late 18th and early 19th centuries. From focusing on supplying the British market to supplying East Asia with raw cotton. As the Artisan produced textiles were no longer competitive with those produced Industrially, and Europe preferring the cheaper slave produced, long staple American, and Egyptian cottons, for its own materials. The advent of

3410-585: The 20th century, these mountains have been the setting for the Tajikistan Civil War , border disputes between China and the Soviet Union , establishment of military bases by the US, Russia, and India, and renewed interest in trade development and resource exploration. The Chinese government says it has resolved most of the disputes it had with Central Asian countries. Some researchers identify

3520-617: The 77 km (48 mi) long Fedchenko Glacier , the longest in the former USSR and the longest glacier outside the polar regions . Approximately 12,500 km (ca. 10%) of the Pamirs are glaciated. Glaciers in the Southern Pamirs are retreating rapidly. Ten percent of annual runoff is supposed to originate from retreating glaciers in the Southern Pamirs. In the North-Western Pamirs, glaciers have almost stable mass balances . Covered in snow during most of

3630-708: The Arabs were not familiar with cotton until the Wars of Alexander the Great , as his contemporary Megasthenes told Seleucus I Nicator of "there being trees on which wool grows" in "Indica." This may be a reference to "tree cotton", Gossypium arboreum , which is native to the Indian subcontinent. According to the Columbia Encyclopedia : Cotton has been spun, woven, and dyed since prehistoric times. It clothed

3740-527: The British and Russians agreed to an Afghan frontier along the Panj River. From 1871 to around 1893 several Russian military-scientific expeditions mapped out most of the Pamirs ( Alexei Pavlovich Fedchenko , Nikolai Severtzov , Captain Dmitry Putyata and others. Later came Nikolai Korzhenevskiy ). Several local groups asked for Russian protection from Afghan raiders. The Russians were followed by

3850-668: The British to cheap calico and chintz cloth on the restoration of the monarchy in the 1660s. Initially imported as a novelty side line, from its spice trading posts in Asia, the cheap colourful cloth proved popular and overtook the EIC's spice trade by value in the late 17th century. The EIC embraced the demand, particularly for calico , by expanding its factories in Asia and producing and importing cloth in bulk, creating competition for domestic woollen and linen textile producers. The impacted weavers, spinners, dyers, shepherds and farmers objected and

3960-573: The Eastern Pamirs, China's Kongur Tagh is the highest at 7,649 m (25,095 ft). Among the significant peaks of the Pamir Mountains are the following: Remark : The summits of the Kongur and Muztagata Group are in some sources counted as part of the Kunlun , which would make Pik Ismoil Somoni the highest summit of the Pamir. There are many glaciers in the Pamir Mountains, including

4070-633: The Egyptian cotton industry. By the time of the American Civil war annual exports had reached $ 16 million (120,000 bales), which rose to $ 56 million by 1864, primarily due to the loss of the Confederate supply on the world market. Exports continued to grow even after the reintroduction of US cotton, produced now by a paid workforce, and Egyptian exports reached 1.2 million bales a year by 1903. The English East India Company (EIC) introduced

4180-495: The Mughal era. It was reported that, with an Indian cotton gin, which is half machine and half tool, one man and one woman could clean 28 pounds (13 kg) of cotton per day. With a modified Forbes version, one man and a boy could produce 250 pounds (110 kg) per day. If oxen were used to power 16 of these machines, and a few people's labour was used to feed them, they could produce as much work as 750 people did formerly. In

4290-468: The Northern and Southern hemispheres, but a large proportion of the cotton grown today is cultivated in areas with less rainfall that obtain the water from irrigation. Production of the crop for a given year usually starts soon after harvesting the preceding autumn. Cotton is naturally a perennial but is grown as an annual to help control pests. Planting time in spring in the Northern hemisphere varies from

4400-509: The Nurek as tallest in the world. This project has caused great controversy. Just as energy dependence threatens Tajikistan, so water dependence threatens the downstream nations. For this reason, Uzbekistan was highly critical of the Rogun Dam, claiming that it would “put it [Tajikistan] firmly in control of the river”. The World Bank responded to these tensions by launching investigations into

4510-482: The Pamir Mountains are referred by different names. In Indo-European languages , they are called: In Turkic languages , they are called: In Chinese , they are referred as "Onion Range" ( simplified Chinese : 葱岭 ; traditional Chinese : 蔥嶺 ; pinyin : Cōnglǐng ; Wade–Giles : Ts'ung-ling ), which is named after the wild onions growing in the region; In the Dungan dialect of Mandarin , it

4620-495: The Pamir Mountains were considered a strategic trade route between Kashgar and Kokand on the Northern Silk Road , a prehistoric trackway, and have been subject to numerous territorial conquests. The Northern Silk Road (about 2,600 km (1,616 mi) in length) connected the ancient Chinese capital Chang'an with Kashgar over the Pamir Mountains towards the west, and from there continued to ancient Parthia . In

4730-469: The Pamirs with the Mount Meru or Sumeru. The Mount Meru is the sacred five-peaked mountain of Buddhist and Jain , and is considered to be the center of all the physical , metaphysical and spiritual universes. Cotton Cotton (from Arabic al-qutn ) is a soft, fluffy staple fiber that grows in a boll , or protective case, around the seeds of the cotton plants of

4840-517: The Soviet Union built many industries nearby. The Tajik Aluminum Company plant is a prime example. Other industries established locally were chemical plants, nitrogen fertilizer factories, and cotton gins. The dams, particularly the reservoirs behind them, were also built with the purpose of providing water for agriculture. The Soviet Union promoted cotton farming in the Vakhsh Valley, as well as vineyards and orchards , and drew water from

4950-540: The United States, even with the use of humans as slave labor. The gin that Whitney manufactured (the Holmes design) reduced the hours down to just a dozen or so per bale. Although Whitney patented his own design for a cotton gin, he manufactured a prior design from Henry Odgen Holmes, for which Holmes filed a patent in 1796. Improving technology and increasing control of world markets allowed British traders to develop

5060-460: The Vakhsh basin has left the river polluted with fertilizers, pesticides, and salts. Also, chemicals have leached into groundwater from the heavy industries near the Vakhsh's dams, which has in turn contaminated surface water. However, ever since Tajikistan lost their Soviet agricultural subsidies with the breakup of the Soviet Union , farms have not been able to afford as many fertilizers or pesticides as before, thus decreasing levels of pollution in

5170-505: The Vakhsh for irrigation. The Vakhsh Valley Canal Project, which expanded farmland along the river's lower reaches, predated the dams, having been completed in 1933. In the 1960s, after the reservoirs had been constructed, engineers dug tunnels through the surrounding mountains to irrigate other valleys. Water storage in the reservoirs also helped control the river's flow, so as to provide a more reliable water supply for downstream users in Uzbekistan and Turkmenistan . Soviet Central Asia had

5280-413: The Vakhsh proper begins at the confluence of the Obikhingou and Surkhob rivers. After it exits the Pamirs, the Vakhsh passes through the fertile lowlands of southwest Tajikistan. It ends when it flows into the Panj to form the Amu Darya, at the border of Tajikistan and Afghanistan . The Tigrovaya Balka Nature Reserve , which was the last habitat of the now-extinct Caspian tiger in the former USSR ,

5390-403: The Vakhsh, in order to promote economic growth and move towards energy independence. Another four dams are planned or under construction, including the Rogun Dam . The Rogun Dam began construction in Soviet times but remains uncompleted; now Tajikistan has recommenced the project with financial support from the Russian Aluminum Company . If constructed to its full planned height, it will supersede

5500-423: The Vakhsh. The Perepadnaya power station, was the first to be commissioned in 1959. It is situated on a canal off the Golovnaya Dam which was commissioned in 1963. The giant Nurek dam was constructed between 1961 and 1980. Baipaza Dam was completed in 1983. To build transmission lines over the Pamirs would have been prohibitively expensive, so, in order to take advantage of the electricity produced by these dams,

5610-402: The Wakhan River. There are various Arab and Chinese reports. Marco Polo may have travelled along the Panj River . In 1602 Bento de Goes travelled from Kabul to Yarkand and left a meager report on the Pamirs. In 1838 Lieutenant John Wood reached the headwaters of the Pamir River . From about 1868 to 1880, a number of Indians in the British service secretly explored the Panj area. In 1873

5720-412: The area and camped near the present Murghab . In 1893 they built a proper fort there ( Pamirskiy Post ). In 1895 their base was moved to Khorog facing the Afghans. In 1928 the last blank areas around the Fedchenko Glacier were mapped by a German-Soviet expedition under Willi Rickmer Rickmers. In the early 1980s, a deposit of gemstone -quality clinohumite was discovered in the Pamir Mountains. It

5830-411: The backbone of the southern American economy. In the United States, cultivating and harvesting cotton became the leading occupation of slaves . During the American Civil War , American cotton exports slumped due to a Union blockade on Southern ports , and because of a strategic decision by the Confederate government to cut exports, hoping to force Britain to recognize the Confederacy or enter

5940-424: The basis of a new indigenous industry, initially producing Fustian for the domestic market, though more importantly triggering the development of a series of mechanised spinning and weaving technologies, to process the material. This mechanised production was concentrated in new cotton mills , which slowly expanded until by the beginning of the 1770s seven thousand bales of cotton were imported annually, and pressure

6050-519: The beginning of February to the beginning of June. The area of the United States known as the South Plains is the largest contiguous cotton-growing region in the world. While dryland (non-irrigated) cotton is successfully grown in this region, consistent yields are only produced with heavy reliance on irrigation water drawn from the Ogallala Aquifer . Since cotton is somewhat salt and drought tolerant, this makes it an attractive crop for arid and semiarid regions. As water resources get tighter around

6160-434: The calico question became one of the major issues of National politics between the 1680s and the 1730s. Parliament began to see a decline in domestic textile sales, and an increase in imported textiles from places like China and India . Seeing the East India Company and their textile importation as a threat to domestic textile businesses, Parliament passed the 1700 Calico Act, blocking the importation of cotton cloth. As there

6270-427: The capsule and seeds sit inside the Chang'e 4 lander. Successful cultivation of cotton requires a long frost -free period, plenty of sunshine, and a moderate rainfall, usually from 50 to 100 cm (19.5 to 39.5 in). Soils usually need to be fairly heavy , although the level of nutrients does not need to be exceptional. In general, these conditions are met within the seasonally dry tropics and subtropics in

6380-404: The decentralization of industry as a way to counter the colonial exploitation of indigenous peoples, but the USSR had strategic aims as well, especially in World War II when industry was evacuated eastward away from the German front. This industrialization would be fueled by exploiting Tajikistan's enormous hydropower potential. It took until the 1950s, however, for dam construction to begin on

6490-443: The dual-roller gin was prevalent throughout the Mediterranean cotton trade by the 16th century. This mechanical device was, in some areas, driven by water power. The earliest clear illustrations of the spinning wheel come from the Islamic world in the eleventh century. The earliest unambiguous reference to a spinning wheel in India is dated to 1350, suggesting that the spinning wheel was likely introduced from Iran to India during

6600-457: The early 19th century had the fifth most productive cotton industry in the world, in terms of the number of spindles per capita. The industry was initially driven by machinery that relied on traditional energy sources, such as animal power , water wheels , and windmills , which were also the principal energy sources in Western Europe up until around 1870. It was under Muhammad Ali in the early 19th century that steam engines were introduced to

6710-487: The early 19th century, a Frenchman named M. Jumel proposed to the great ruler of Egypt, Mohamed Ali Pasha , that he could earn a substantial income by growing an extra-long staple Maho ( Gossypium barbadense ) cotton, in Lower Egypt , for the French market. Mohamed Ali Pasha accepted the proposition and granted himself the monopoly on the sale and export of cotton in Egypt ; and later dictated cotton should be grown in preference to other crops. Egypt under Muhammad Ali in

The other four dams, downstream of Nurek, are Baipaza , Sangtuda 1 , Sangtuda 2 and Golovnaya Dams . (These dams make Tajikistan the highest hydroelectric power producer per capita in the world.) Hydroelectricity powers the aluminum production at the Tajik Aluminum Company in Tursunzoda ,

7040-517: The fossil-fuel-rich downstream nations supplied Tajikistan with oil and gas to compensate for forgone hydroelectricity generation. However, with increasing regional tension post-independence, this system is breaking down, with no conclusive cooperative arrangement yet. Fuel deliveries from downstream nations have been getting less reliable and more expensive, and impoverished Tajikistan cannot adapt by increasing winter hydroelectric generation since this would jeopardize irrigation and electricity exports in

7150-421: The fourth largest GM cotton crop area of 2.6 million hectares in 2011. The initial introduction of GM cotton proved to be a success in Australia – the yields were equivalent to the non-transgenic varieties and the crop used much less pesticide to produce (85% reduction). The subsequent introduction of a second variety of GM cotton led to increases in GM cotton production until 95% of the Australian cotton crop

7260-403: The genetics of white cotton have led many cotton-growing locations to ban the growing of colored cotton varieties. The word "cotton" has Arabic origins , derived from the Arabic word قطن ( qutn or qutun ). This was the usual word for cotton in medieval Arabic . Marco Polo in chapter 2 in his book, describes a province he calls Khotan in Turkestan, today's Xinjiang , where cotton

7370-439: The genus Gossypium in the mallow family Malvaceae . The fiber is almost pure cellulose , and can contain minor percentages of waxes , fats , pectins , and water . Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species

7480-417: The glacier snowline (ELA ) as altitude limit between glacier nourishing area and ablation zone, was about 820 to 1250 metres lower than it is today. Under the condition of comparable proportions of precipitation there results from this a glacial depression of temperature of at least 5 to 7.5 °C. Coal is mined in the west, though sheep herding in upper meadowlands is the primary source of income for

7590-496: The heart of the global cotton trade. Production capacity in Britain and the United States was improved by the invention of the modern cotton gin by the American Eli Whitney in 1793. Before the development of cotton gins, the cotton fibers had to be pulled from the seeds tediously by hand. By the late 1700s, a number of crude ginning machines had been developed. However, to produce a bale of cotton required over 600 hours of human labor, making large-scale production uneconomical in

7700-549: The knowledge of its spinning and weaving in Meroë reached a high level. The export of textiles was one of the sources of wealth for Meroë. Ancient Nubia had a "culture of cotton" of sorts, evidenced by physical evidence of cotton processing tools and the presence of cattle in certain areas. Some researchers propose that cotton was important to the Nubian economy for its use in contact with the neighboring Egyptians. Aksumite King Ezana boasted in his inscription that he destroyed large cotton plantations in Meroë during his conquest of

7810-423: The largest exporter for many years. There are four commercially grown species of cotton, all domesticated in antiquity: Hybrid varieties are also cultivated. The two New World cotton species account for the vast majority of modern cotton production, but the two Old World species were widely used before the 1900s. While cotton fibers occur naturally in colors of white, brown, pink and green, fears of contaminating

7920-477: The main pests in commercial cotton are lepidopteran larvae, which are killed by the Bt protein in the transgenic cotton they eat. This eliminates the need to use large amounts of broad-spectrum insecticides to kill lepidopteran pests (some of which have developed pyrethroid resistance). This spares natural insect predators in the farm ecology and further contributes to noninsecticide pest management. However, Bt cotton

8030-482: The major products of Persia, including cotton. John Chardin , a French traveler of the 17th century who visited Safavid Persia , spoke approvingly of the vast cotton farms of Persia. Cotton ( Gossypium herbaceum Linnaeus) may have been domesticated 5000 BC in eastern Sudan near the Middle Nile Basin region, where cotton cloth was being produced. Around the 4th century BC, the cultivation of cotton and

8140-405: The name for cotton in several Germanic languages, such as German Baumwolle , which translates as "tree wool" ( Baum means "tree"; Wolle means "wool"). Noting its similarities to wool, people in the region could only imagine that cotton must be produced by plant-borne sheep. John Mandeville , writing in 1350, stated as fact that "There grew there [India] a wonderful tree which bore tiny lambs on

8250-480: The new textile industries of the Northeastern United States and northwestern Europe. In 1860 the slogan " Cotton is king " characterized the attitude of Southern leaders toward this monocrop in that Europe would support an independent Confederate States of America in 1861 in order to protect the supply of cotton it needed for its very large textile industry. Russell Griffin of California was

8360-826: The north, they join the Tian Shan mountains along the Alay Valley of Kyrgyzstan . To the east, they extend to the range that includes China 's Kongur Tagh , in the "Eastern Pamirs", separated by the Yarkand valley from the Kunlun Mountains . Since the Victorian era , they have been known as the " Roof of the World ", presumably a translation from Persian . The Pamir region is home to several different cultures, peoples and languages. In some of these languages,

8470-640: The north-east through the Gez valley up to c.1850 m asl (meters above sea level) and thus as far as to the margin of the Tarim basin. This outlet glacier received inflow from the Kaiayayilak glacier from the Kongur north flank. From the north-adjacent Kara Bak Tor (Chakragil, c. 6800 or 6694 m) massif, the Oytag valley glacier in the same exposition flowed also down up to c. 1850 m asl. At glacial times

8580-868: The people of ancient India, Egypt, and China. Hundreds of years before the Christian era, cotton textiles were woven in India with matchless skill, and their use spread to the Mediterranean countries. In Iran ( Persia ), the history of cotton dates back to the Achaemenid era (5th century BC); however, there are few sources about the planting of cotton in pre-Islamic Iran. Cotton cultivation was common in Merv , Ray and Pars . In Persian poems, especially Ferdowsi 's Shahname , there are references to cotton ("panbe" in Persian ). Marco Polo (13th century) refers to

8690-410: The raw fiber was sent to England for processing. The Indian Mahatma Gandhi described the process: In the United States, growing Southern cotton generated significant wealth and capital for the antebellum South, as well as raw material for Northern textile industries. Before 1865 the cotton was largely produced through the labor of enslaved African Americans. It enriched both the Southern landowners and

8800-616: The region. In the Meroitic Period (beginning 3rd century BCE), many cotton textiles have been recovered, preserved due to favorable arid conditions. Most of these fabric fragments come from Lower Nubia, and the cotton textiles account for 85% of the archaeological textiles from Classic/Late Meroitic sites. Due to these arid conditions, cotton, a plant that usually thrives moderate rainfall and richer soils, requires extra irrigation and labor in Sudanese climate conditions. Therefore,

8910-526: The region. The lapis lazuli found in Egyptian tombs is thought to come from the Pamir area in Badakhshan province of Afghanistan. About 138 BCE Zhang Qian reached the Fergana Valley northwest of the Pamirs. Ptolemy vaguely describes a trade route through the area. From about 600 CE, Buddhist pilgrims travelled on both sides of the Pamirs to reach India from China. In 747 a Tang army was on

9020-662: The rest of Europe. The spinning wheel , introduced to Europe circa 1350, improved the speed of cotton spinning. By the 15th century, Venice , Antwerp , and Haarlem were important ports for cotton trade, and the sale and transportation of cotton fabrics had become very profitable. Under the Mughal Empire , which ruled in the Indian subcontinent from the early 16th century to the early 18th century, Indian cotton production increased, in terms of both raw cotton and cotton textiles. The Mughals introduced agrarian reforms such as

9130-441: The river valley. The Vakhsh is located in a seismically active region, and earthquakes , in addition to high groundwater levels (especially during the wet season), cause hundreds of landslides per year. These landslides occasionally block the river and form landslide dams . Such blockages pose a significant threat to the river's dams and hydroelectric power generation. A large landslide 8 kilometers (5 mi) downstream from

9240-456: The river. The 2008 financial crisis has further increased poverty, which in turn has further decreased pollution. Since the waters of the Vakhsh eventually flow into the Aral Sea , pollution in the Vakhsh contributes to eutrophication there. The Vakhsh is fed by the glaciers of the Pamirs, one of the world's most susceptible regions to climate change. Tajikistan as a whole has experienced

9350-425: The social and environmental impacts of the dam. However, following the death of its former leader Islam Karimov in 2016, in 2018 Uzbekistan dropped its opposition to the Rogun Dam. "Go ahead and build it, but we hold to certain guarantees in accordance with these conventions that have been signed by you," Uzbek Foreign Minister Abdulaziz Komilov said in a televised appearance on July 5, 2018. Intensive agriculture in

9460-523: The summer. This dependence has caused energy crises in the winters of 2008 and 2009, in which the capital, Dushanbe , lost power and heating. Heightened nationalism and border disputes further complicate the search for a solution to Central Asia's water needs, according to a study conducted by the International Crisis Group . Tajikistan is therefore pursuing a course of action to increase hydroelectric capacity by building more dams on

9570-519: The use of pesticides at similar levels to non-Bt cotton and causing less profit for farmers because of the extra expense of GM seeds. However, a 2009 study by the Chinese Academy of Sciences, Stanford University and Rutgers University refuted this. They concluded that the GM cotton effectively controlled bollworm. The secondary pests were mostly miridae (plant bugs) whose increase was related to local temperature and rainfall and only continued to increase in half

9680-442: The villages and then taken to towns in the form of yarn to be woven into cloth textiles, was advanced by the diffusion of the spinning wheel across India shortly before the Mughal era, lowering the costs of yarn and helping to increase demand for cotton. The diffusion of the spinning wheel, and the incorporation of the worm gear and crank handle into the roller cotton gin, led to greatly expanded Indian cotton textile production during

9790-506: The villages studied. Moreover, the increase in insecticide use for the control of these secondary insects was far smaller than the reduction in total insecticide use due to Bt cotton adoption. A 2012 Chinese study concluded that Bt cotton halved the use of pesticides and doubled the level of ladybirds, lacewings and spiders. The International Service for the Acquisition of Agri-biotech Applications (ISAAA) said that, worldwide, GM cotton

9900-543: The war. The Lancashire Cotton Famine prompted the main purchasers of cotton, Britain and France , to turn to Egyptian cotton. British and French traders invested heavily in cotton plantations. The Egyptian government of Viceroy Isma'il took out substantial loans from European bankers and stock exchanges. After the American Civil War ended in 1865, British and French traders abandoned Egyptian cotton and returned to cheap American exports, sending Egypt into

10010-575: The western margin of the Tarim Basin an east–west extension of c. 200 km. Its north–south extension from King Ata Tagh up to the northwest Kunlun foothills amounts to c.170 km. Whilst the up to 21 km long current valley glaciers are restricted to mountain massifs exceeding 5600 m in height, during the last glacial period the glacier ice covered the high plateau with its set-up highland relief, continuing west of Mustagh Ata and Kongur. From this glacier area an outlet glacier has flowed down to

10120-467: The world, economies that rely on it face difficulties and conflict, as well as potential environmental problems. For example, improper cropping and irrigation practices have led to desertification in areas of Uzbekistan , where cotton is a major export. In the days of the Soviet Union , the Aral Sea was tapped for agricultural irrigation, largely of cotton, and now salination is widespread. Cotton can also be cultivated to have colors other than

10230-529: The world. A long-term study on the economic impacts of Bt cotton in India, published in the Journal PNAS in 2012, showed that Bt cotton has increased yields, profits, and living standards of smallholder farmers. The U.S. GM cotton crop was 4.0 million hectares in 2011 the second largest area in the world, the Chinese GM cotton crop was third largest by area with 3.9 million hectares and Pakistan had

10340-528: The worst-case scenario, failure of a landslide dam could cause catastrophic floods. Recognizing these threats, the Asian Development Bank responded to the landslide of 2002 by granting the government of Tajikistan a low-interest loan to stabilize the valley slopes and mitigate the potential for blockages in the future. Pamirs The Pamir Mountains are a range of mountains between Central Asia and South Asia . They are located at

10450-455: The year, the Pamirs have long and bitterly cold winters , and short, cool summers , which equals an ET (tundra climate) according to Köppen climate classification ( EF above the snow line). Annual precipitation is about 130 mm (5 in), which supports grasslands but few trees . The East-Pamir, in the centre of which the massifs of Mustagh Ata (7620 m) and Kongur Tagh (Qungur Shan, 7578, 7628 or 7830 m) are situated, shows from

10560-523: The yellowish off-white typical of modern commercial cotton fibers. Naturally colored cotton can come in red, green, and several shades of brown. The water footprint of cotton fibers is substantially larger than for most other plant fibers. Cotton is also known as a thirsty crop; on average, globally, cotton requires 8,000–10,000 liters of water for one kilogram of cotton, and in dry areas, it may require even more such as in some areas of India, it may need 22,500 liters. Genetically modified (GM) cotton

10670-426: Was GM in 2009 making Australia the country with the fifth largest GM cotton crop in the world. Other GM cotton growing countries in 2011 were Argentina, Myanmar, Burkina Faso, Brazil, Mexico, Colombia, South Africa and Costa Rica. Cotton has been genetically modified for resistance to glyphosate a broad-spectrum herbicide discovered by Monsanto which also sells some of the Bt cotton seeds to farmers. There are also

10780-559: Was a source of income for families across the South. Rural and small town school systems had split vacations so children could work in the fields during "cotton-picking." During the middle 20th century, employment in cotton farming fell, as machines began to replace laborers and the South's rural labor force dwindled during the World Wars. Cotton remains a major export of the United States, with large farms in California, Arizona and

10890-459: Was developed to reduce the heavy reliance on pesticides. The bacterium Bacillus thuringiensis (Bt) naturally produces a chemical harmful only to a small fraction of insects, most notably the larvae of moths and butterflies , beetles , and flies , and harmless to other forms of life. The gene coding for Bt toxin has been inserted into cotton, causing cotton, called Bt cotton , to produce this natural insecticide in its tissues. In many regions,

11000-401: Was grown by Chinese peoples in the southern Chinese province of Yunnan . Egyptians grew and spun cotton in the first seven centuries of the Christian era. Handheld roller cotton gins had been used in India since the 6th century, and was then introduced to other countries from there. Between the 12th and 14th centuries, dual-roller gins appeared in India and China. The Indian version of

11110-714: Was grown in abundance. The word entered the Romance languages in the mid-12th century, and English a century later. Cotton fabric was known to the ancient Romans as an import, but cotton was rare in the Romance-speaking lands until imports from the Arabic-speaking lands in the later medieval era at transformatively lowered prices. The earliest evidence of the use of cotton in the Old World , dated to 5500 BC and preserved in copper beads, has been found at

11220-418: Was imported from India without tariffs to British factories which manufactured textiles from Indian cotton, giving Britain a monopoly over India's large market and cotton resources. India served as both a significant supplier of raw goods to British manufacturers and a large captive market for British manufactured goods. Britain eventually surpassed India as the world's leading cotton textile manufacturer in

11330-451: Was invented in India during the early Delhi Sultanate era of the 13th–14th centuries, came into use in the Mughal Empire some time around the 16th century, and is still used in India through to the present day. Another innovation, the incorporation of the crank handle in the cotton gin, first appeared in India some time during the late Delhi Sultanate or the early Mughal Empire. The production of cotton, which may have largely been spun in

11440-443: Was no punishment for continuing to sell cotton cloth, smuggling of the popular material became commonplace. In 1721, dissatisfied with the results of the first act, Parliament passed a stricter addition, this time prohibiting the sale of most cottons, imported and domestic (exempting only thread Fustian and raw cotton). The exemption of raw cotton from the prohibition initially saw 2 thousand bales of cotton imported annually, to become

11550-422: Was planted on an area of 25 million hectares in 2011. This was 69% of the worldwide total area planted in cotton. GM cotton acreage in India grew at a rapid rate, increasing from 50,000 hectares in 2002 to 10.6 million hectares in 2011. The total cotton area in India was 12.1 million hectares in 2011, so GM cotton was grown on 88% of the cotton area. This made India the country with the largest area of GM cotton in

11660-400: Was put on Parliament, by the new mill owners, to remove the prohibition on the production and sale of pure cotton cloth, as they could easily compete with anything the EIC could import. The acts were repealed in 1774, triggering a wave of investment in mill-based cotton spinning and production, doubling the demand for raw cotton within a couple of years, and doubling it again every decade, into

11770-603: Was responsible for a large part of the empire's international trade. India had a 25% share of the global textile trade in the early 18th century. Indian cotton textiles were the most important manufactured goods in world trade in the 18th century, consumed across the world from the Americas to Japan . The most important center of cotton production was the Bengal Subah province, particularly around its capital city of Dhaka . The worm gear roller cotton gin , which

11880-407: Was the invention of the cotton gin that lowered the cost of production that led to its widespread use, and it is the most widely used natural fiber cloth in clothing today. Current estimates for world production are about 25 million tonnes or 110 million bales annually, accounting for 2.5% of the world's arable land . India is the world's largest producer of cotton. The United States has been

11990-739: Was the only such deposit known until the discovery of gem-quality material in the Taymyr region of Siberia , in 2000. The earliest known evidence of human cannabis use was found in tombs at the Jirzankal Cemetery. The Pamir Highway , the world's second highest international road, runs from Dushanbe in Tajikistan to Osh in Kyrgyzstan through the Gorno-Badakhshan Autonomous Province , and

12100-461: Was time-consuming and expensive. This, coupled with the emergence of American cotton as a superior type (due to the longer, stronger fibers of the two domesticated native American species, Gossypium hirsutum and Gossypium barbadense ), encouraged British traders to purchase cotton from plantations in the United States and in the Caribbean . By the mid-19th century, " King Cotton " had become
