History of rice cultivation

The history of rice cultivation is an interdisciplinary subject that studies archaeological and documentary evidence to explain how rice was first domesticated and cultivated by humans, the spread of cultivation to different regions of the planet, and the technological changes that have impacted cultivation over time.

History
Asia (8500 to 1500 BC), showing the approximate locations of the Hemudu, Majiabang, and Liangzhu cultures (associated with pre-Austronesians); and the Pengtoushan, Daxi, and Qujialing cultures (associated with the Hmong–Mien speakers), along the Lower and Upper Yangtze basin The scientific consensus based on archaeological and linguistic evidence, is that rice was first domesticated in the Yangtze River basin in China. A more recent population genomic study indicates that japonica was domesticated first, and that indica rice arose when japonica arrived in India about ~4,500 years ago and hybridized with an undomesticated proto-indica or wild O. nivara. There are two most likely centers of domestication for rice as well as the development of the wetland agriculture technology. The first is in the lower Yangtze River, believed to be the homelands of the pre-Austronesians and possibly also the Kra–Dai, and associated with the Kauhuqiao, Hemudu, Majiabang, Songze, Liangzhu, and Maqiao cultures. It is characterized by pre-Austronesian features, including stilt houses, jade carving, and boat technologies. The second is in the middle Yangtze River, believed to be the homelands of the early Hmong–Mien speakers and associated with the Pengtoushan, Nanmuyuan, Liulinxi, Daxi, Qujialing, and Shijiahe cultures. Both of these regions were heavily populated and had regular trade contacts with each other, as well as with early Austroasiatic speakers to the west, and early Kra–Dai speakers to the south, facilitating the spread of rice cultivation throughout southern China. Rice was gradually introduced north into the early Sino-Tibetan Yangshao and Dawenkou culture millet farmers, either via contact with the Daxi culture or the Majiabang-Hemudu culture. By around 4000 to 3800 BC, they were a regular secondary crop among southernmost Sino-Tibetan cultures. It did not replace millet, largely because of different environment conditions in northern China, but it was cultivated alongside millet in the southern boundaries of the millet-farming regions. Conversely, millet was also introduced into rice-farming regions. By the late Neolithic (3500 to 2500 BC), population in the rice cultivating centers had increased rapidly, centered around the Qujialing-Shijiahe culture and the Liangzhu culture. There was also evidence of intensive rice cultivation in paddy fields as well as increasingly sophisticated material cultures in these two regions. Both the number of settlements and overall settlement sizes increased among the Yangtze cultures, leading some archeologists to characterize them as true states, with clearly advanced socio-political structures. However, it is unknown if they had centralized control. Liangzhu and Shijiahe declined abruptly in the terminal Neolithic (2500 to 2000 BC). With Shijiahe shrinking in size, and Liangzhu disappearing altogether. This is largely believed to be the result of the southward expansion of the early Sino-Tibetan Longshan culture. Fortifications like walls (as well as extensive moats in Liangzhu cities) are common features in settlements during this period, indicating widespread conflict. This period also coincides with the southward movement of rice-farming cultures to the Lingnan and Fujian regions, as well as the southward migrations of the Austronesian, Kra–Dai, and Austroasiatic-speaking peoples to Mainland Southeast Asia and Island Southeast Asia. A genomic study also indicates that at around this time, a global cooling event (the 4.2 k event) led to tropical japonica rice being pushed southwards, as well as the evolution of temperate japonica rice that could grow in more northern latitudes. Genomic studies suggests that indica rice was later introduced back to China from India between 2,000 and 1,400 years ago. Rice, along with other Southeast Asian food plants, were also later introduced to Madagascar, the Comoros, and the coast of East Africa by around the 1st millennium AD by Austronesian settlers from the Greater Sunda Islands. Much later Austronesian voyages from Island Southeast Asia succeeded in bringing rice to Guam during the Latte Period (AD 900 to AD 1700). Guam is the only island in Oceania where rice was grown in pre-colonial times. Within Mainland Southeast Asia, rice was presumably spread through river trade between the early Hmong–Mien speakers of the Middle Yangtze basin and the early Kra–Dai speakers of the Pearl River and Red River basins, as well as the early Austroasiatic speakers of the Mekong River basin. Evidence for rice cultivation in these regions, dates to slightly later than the Dapenkeng settlement of Taiwan, at around 3000 BC. Southward migrations of the Austroasiatic and Kra–Dai speakers introduced it into Mainland Southeast Asia. The earliest evidence of rice cultivation in Mainland Southeast Asia come from the Ban Chiang site in northern Thailand (ca. 2000 to 1500 BC); and the An Sơn site in southern Vietnam (ca. 2000 to 1200 BC). A genomic study indicates that rice diversified into Maritime Southeast Asia between 2,500 and 1,500 years ago. A genomic study indicates that temperate japonica, which predominates in Korea and Japan, evolved after a global cooling event (the 4.2k event) that occurred 4,200 years ago. However, whether or not the samples at Lahuradewa belong to domesticated rice is still disputed: earliest unambiguous domesticated rice grains of Northern India are dated ca. 2000 BCE, whereas other rice grains dated during ca. 4800 to 3500 BCE are considered as wild or uncertain whether wild/domesticated. Rice was consumed in the Indian subcontinent from as early as 5,000 BC: "Several wild cereals, including rice, grew in the Vindhyan Hills, and rice cultivation, at sites such as Chopani-Mando and Mahagara, may have been underway as early as 7,000 BP." Rice appeared in the Ganges valley regions of northern India as early as 4530 BC and 5440 BC, respectively. The early domestication process of rice in ancient India was based around the wild species Oryza nivara. This led to the local development of a mix of 'wetland' and 'dryland' agriculture of local Oryza sativa var. indica rice agriculture, before the truly 'wetland' rice Oryza sativa var. japonica, arrived around 2000 BC. In the Ganges Plain, the unambiguous beginning of Neolithic sites with evidence of rice farming is after mid-3rd millennium BCE, and mainly after 2000 BCE, with older "possible origins" in 4th millennium BCE. Earlier datings of 7th millennium BCE have been called into question, as the earliest remains at such sites as Lahuradewa are more likely considered as "intermittent" occupation by hunter-gatherers who collected wild rice and hunted wild animals, and it probably was not until the 3rd millennium BCE when settlement became "more regular" with unambiguous evidence of domesticated rice and domesticated animals. Agricultural activity during the second millennium BC included rice cultivation in the Kashmir and Harrappan regions. Africa Although Oryza sativa was domesticated in Asia, the now less popular Oryza glaberrima rice was independently domesticated in Africa 3,000 to 3,500 years ago. African women's involvement in the cultivation of rice throughout Africa is vital. They play a significant role in rice cultivation in Africa through their rice farming practices and traditional production methods that highlight their importance in the rice production field. African women through the course of history have harvested the rice crop and furthermore provided a principal food staple of the Western region of Africa. Europe (Northern Italy) in 1920s -Valencian Country) Rice was known to the Classical world, being imported from Egypt, and perhaps west Asia. It was known to Greece (where it is still cultivated in Macedonia and Thrace) by returning soldiers from Alexander the Great's military expedition to Asia. Large deposits of rice from the first century AD have been found in Roman camps in Germany. However, it was not a staple of the Greek diet until the 10th century. Prior to this, barley and wheat were the primary grains cultivated and consumed in Greece. Over time, rice gradually replaced these traditional grains as a staple ingredient in many Greek dishes. The Moors brought Asiatic rice to the Iberian Peninsula in the 8th century where it expanded progressively from the south. In Majorca, rice cultivation seems to have stopped after the Christian reconquest, although historians are not certain. The Moors may have also brought rice to Sicily, with cultivation starting in the 9th century, where it was an important crop After the 15th century, rice spread throughout Italy and then France, later propagating to all the continents during the age of European exploration. In Russia, a short-grain, starchy rice similar to the Italian varieties, has been grown in the Krasnodar Krai, and known in Russia as "Kuban Rice" or "Krasnodar Rice". In the Russian Far East several japonica cultivars are grown in Primorye around the Khanka lake. Increasing scale of rice production in the region has recently brought criticism towards growers' alleged bad practices in regard to the environment. America Recent research indicates that rice was independently domesticated in South America before the 14th century from Amazon wild rice. Controversies The origin of Oryza sativa rice domestication has been a subject of much debate among those who study crop history and anthropology – whether rice originated in India or China. Asian rice, Oryza sativa, is one of the oldest crop species. It has tens of thousands of varieties and two major subspecies, japonica and indica. Archeologists focusing on East and Southeast Asia argue that rice farming began in south-central China along the Yangtze River and spread to Korea and Japan from there south and northeast. and Indus valley, by peoples unconnected to those of the Yangtze. The study is based on modern distribution maps of wild rice populations which may be potentially inconclusive due to drastic climatic changes that happened during the end of the last glacial period, ca. 12,000 years ago. However, the climate in regions north of the Pearl River would likely be less suitable for this wild rice. Human activity over thousands of years may also have removed populations of wild rice from their previous ranges. Based on Chinese texts, it is speculated there are populations of native wild rice along the Yangtze basin in c. AD 1,000 that have recently become extinct. In 2003, Korean archaeologists announced they discovered rice husks in Soro-ri, Korea, which dated to 13,000 BC, that they claimed show signs of having been cut by stone tools. These antedates the oldest grains found in China, which were dated to 10,000 BC, and potentially challenge the explanation that domesticated rice originated in the Yangtze River basin of China. The findings were received by academia with strong skepticism and the claim remains dubious. The dates claimed by the authors of the study at Soro-ri are disputed, since they did not use the much more reliable accelerator mass spectrometry (AMS) carbon dating. A 2013 study using AMS carbon dating on seven samples of the actual rice husks have resulted in only one of the samples being dated to 12,520 ± 150 BP, with the other six being discovered to date to modern times. This inconsistency has not been explained. The evidence of the claimed cuts on the rice stalks are also inadequately explained. It is also unlikely for rice to be able to grow in Korea during the Oldest Dryas, when the climate was much colder. Lastly, apart from the husks, no other remains of rice plants have been recovered from the site, which opens the possibility that even if the rice husks were as old as claimed, it is still more likely that they may have been transported from warmer regions in some manner (either by migratory birds or Paleolithic foragers) and were not grown there. == Regional history ==
Regional history
Asia Today, the majority of all rice produced comes from China, India, Indonesia, Bangladesh, Vietnam, Thailand, Myanmar, Philippines, Korea and Japan. Asian farmers still account for 87% of the world's total rice production. Indonesia Rice is a staple food for all classes in contemporary Indonesia, and it holds the central place in Indonesian culture and Indonesian cuisine: it shapes the landscape; is sold at markets; and is served in most meals. Rice accounts for more than half of the calories in the average diet, and the source of livelihood for about 20 million households. The importance of rice in Indonesian culture is demonstrated through the reverence of Dewi Sri, the rice goddess of ancient Java and Bali. Evidence of wild rice on the island of Sulawesi dates from 3000 BC. Historic written evidence for the earliest cultivation, however, comes from eighth century stone inscriptions from the central island of Java, which show kings levied taxes in rice. The images of rice cultivation, rice barn, and mice infesting a rice field is evident in Karmawibhangga bas-reliefs of Borobudur. Divisions of labour between men, women, and animals that are still in place in Indonesian rice cultivation, were carved into relief friezes on the ninth century Prambanan temples in Central Java: a water buffalo attached to a plough; women planting seedlings and pounding grain; and a man carrying sheaves of rice on each end of a pole across his shoulders (pikulan). In the sixteenth century, Europeans visiting the Indonesian islands saw rice as a new prestige food served to the aristocracy during ceremonies and feasts. Pakistan Pakistan is one of the 10 largest rice producing country in the world. Rice of different varieties are cultivated in 3.35 million hectares with an annual production of 8.5 million metric tons () (1.12% percent of global production). Pakistan constitutes 8% share in total world exports. Pakistan is the top exporter of brown rice (). Pakistan exported around 415,053 tons of rice worth . Pakistan constitutes 22.1% share in brown rice exports. The main producing areas are Sindh and Punjab. Pakistan is the 3rd highest rice exporting country in the world in terms of quantity and 4th highest in terms of value. Pakistan exported around 5.8 million tons of rice worth . Philippines , Philippines The Banaue Rice Terraces () are terraces that were carved into the mountains of Ifugao in the Philippines by the ancestors of the Igorot people. The Rice Terraces are commonly referred to as the "Eighth Wonder of the World". It is commonly thought that the terraces were built with minimal equipment, largely by hand. The terraces are located approximately 1,500 meters (5,000 ft) above sea level. They are fed by an ancient irrigation system from the rainforests above the terraces. It is said that if the steps were put end to end, it would encircle half the globe. The terraces are found in the province of Ifugao and the Ifugao people have been its caretakers. Ifugao culture revolves around rice and the culture displays an elaborate array of celebrations linked with agricultural rites from rice cultivation to rice consumption. The harvest season generally calls for thanksgiving feasts, while the concluding harvest rites called tango or tungul (a day of rest) entails a strict taboo on any agricultural work. Partaking of the bayah (rice beer), rice cakes, and betel nut constitutes an indelible practice during the festivities. The Ifugao people practice traditional farming spending most of their labor at their terraces and forest lands while occasionally tending to root crop cultivation. The Ifugaos have also Thailand has a large number of rice varieties, 3,500 kinds with different characters, and five kinds of wild rice cultivates. In each region of the country there are different rice seed types. Their use depends on weather, atmosphere, and topography. The northern region has both lowlands and high lands. The farmers' usual crop is non-glutinous rice The northeastern region is a large area where farmers can cultivate about 36 million square meters of rice. Although most of it is plains and dry areas, white jasmine rice 105—the most famous Thai rice—can be grown there. White jasmine rice was developed in Chonburi Province first and after that grown in many areas in the country, but the rice from this region has a high quality, because it is softer, whiter, and more fragrant. This rice can resist drought, acidic soil, and alkaline soil. The central region is mostly composed of plains. Most farmers grow Jao rice. In the southern region, most farmers transplant around boundaries to the flood plains or on the plains between mountains. Farming in the region is slower than other regions because the rainy season comes later. Companion plant One of the earliest known examples of companion planting is the growing of rice with Azolla, the mosquito fern, which covers the top of a fresh rice paddy's water, blocking out any competing plants, as well as fixing nitrogen from the atmosphere for the rice to use. The rice is planted when it is tall enough to poke out above the azolla. This method has been used for at least a thousand years. (1804) Middle East and the Mediterranean Basin Asiatic rice (Oryza sativa), although a latecomer to Mediterranean agriculture, was relatively widespread in antiquity and was not a product of the Islamic Agricultural Revolution. During the Hellenistic period, rice was well known as far west as Parthia, in modern northeastern Iran. Diodorus (first century BCE) recognized rice as a significant Indian crop during the subcontinent's busy agricultural season. Strabo (first century CE) reported that rice was widely grown in Bactria, Babylon, Susis, and also in Lower Syria, based on second century BCE author Aristobulus. The crop traveled to Asia Minor (in modern-day Turkey) during the early centuries CE. Texts from the late first and early second centuries imply that rice was first introduced to Palestine by Jewish farmers during the Early Roman period. Palestine's main crop was fine, large kernel rice. According to the Jerusalem Talmud (3rd to 4th centuries CE), rice was grown in Caesarea, Paneas-Caesarea Phillipi, and the Chrysopolis area to the north of the Sea of Galilee (in modern-day Israel). Spanish colonizers introduced Asian rice to Mexico in the 1520s at Veracruz, and the Portuguese and Africans they enslaved introduced it at about the same time to colonial Brazil. Recent scholarship suggests that enslaved Africans played an active role in the establishment of rice in the New World and that African rice was an important crop from an early period. Varieties of rice and bean dishes that were a staple dish along the peoples of West Africa remained a staple among their descendants subjected to slavery in the Spanish New World colonies, Brazil and elsewhere in the Americas. Chile The Royal Governor Ambrosio O'Higgins was an early proponent of rice cultivation in Chile during his rule between 1788 and 1796. The first rice cultivation occurred however much later, around 1920, yielding mixed results. officials at a rice farm in California In 1694, rice arrived in South Carolina, probably originating from Madagascar. The mastery of rice farming was a challenge for the English and other European settlers who were unfamiliar with the crop. Native Americans, who mostly gathered wild rice, were also inexperienced with rice cultivation. However, within the first fifty years of settlement rice became the dominant crop in South Carolina. In the United States, colonial South Carolina and Georgia grew and amassed great wealth from the slave labor obtained from the Senegambia area of West Africa and from coastal Sierra Leone. At the port of Charleston, through which 40% of all American slave imports passed, slaves from this region of Africa brought the highest prices due to their prior knowledge of rice culture, which was put to use on the many rice plantations around Georgetown, Charleston, and Savannah. From the enslaved Africans, plantation owners learned how to dyke the marshes and periodically flood the fields. At first the rice was laboriously milled by hand using large mortars and pestles made of wood, then winnowed in sweetgrass baskets (the making of which was another skill brought by slaves from Africa). The invention of the rice mill increased profitability of the crop, and the addition of waterpower for the mills in 1787 by millwright Jonathan Lucas was another step forward. Rice culture in the southeastern U.S. became less profitable with the loss of slave labor after the American Civil War, and it finally died out just after the turn of the 20th century. Today, people can visit the only remaining rice plantation in South Carolina that still has the original winnowing barn and rice mill from the mid-19th century at the historic Mansfield Plantation in Georgetown, South Carolina. The predominant strain of rice in the Carolinas was from Africa and was known as 'Carolina Gold'. The cultivar has been preserved and there are current attempts to reintroduce it as a commercially grown crop. In the southern United States, rice has been grown in southern Arkansas, Louisiana, and east Texas since the mid-19th century. Many Cajun farmers grew rice in wet marshes and low-lying prairies where they could also farm crayfish when the fields were flooded. In recent years rice production has risen in North America, especially in the Mississippi embayment in the states of Arkansas and Mississippi (see also Arkansas Delta and Mississippi Delta). . Rice cultivation began in California during the California Gold Rush, when an estimated 40,000 Chinese laborers immigrated to the state and grew small amounts of the grain for their own consumption. However, commercial production began only in 1912 in the town of Richvale in Butte County. By 2006, California produced the second-largest rice crop in the United States, after Arkansas, with production concentrated in six counties north of Sacramento. Unlike the Arkansas–Mississippi Delta region, California's production is dominated by short- and medium-grain japonica varieties, including cultivars developed for the local climate such as Calrose, which makes up as much as 85% of the state's crop. References to "wild rice" native to North America are to Zizania palustris, and three other species in the related genus Zizania More than 100 varieties of rice are commercially produced primarily in six states (Arkansas, Texas, Louisiana, Mississippi, Missouri, and California) in the U.S. According to estimates for the 2006 crop year, rice production in the U.S. is valued at $1.88 billion, approximately half of which is expected to be exported. The U.S. provides about 12% of world rice trade. Because irrigation water, despite the extremely low runoff of temperate Australia, was (and remains) very cheap, the growing of rice was taken up by agricultural groups over the following decades. Californian varieties of rice were found suitable for the climate in the Riverina, encouraged the expansion of the Riverina rice industry, but its prodigious water use in a practically waterless region began to attract the attention of environmental scientists. These became severely concerned with declining flow in the Snowy River and the lower Murray River. Although rice growing in Australia is highly profitable due to the cheapness of land, several recent years of severe drought have led many to call for its elimination because of its effects on extremely fragile aquatic ecosystems. The Australian rice industry is somewhat opportunistic, with the area planted varying significantly from season to season depending on water allocations in the Murray and Murrumbidgee irrigation regions. Australian Aboriginal people have harvested native rice varieties for thousands of years, and there are ongoing efforts to grow commercial quantities of these species. == References ==
