124-581: Terraced paddy fields are used widely in rice, wheat and barley farming in east , south , southwest , and southeast Asia , as well as the Mediterranean Basin , Africa, and South America. Drier-climate terrace farming is common throughout the Mediterranean Basin, where they are used for vineyards , olive trees, cork oak , and other crops. The Yemen Highlands are known for their terrace systems which were constructed at

248-527: A "historic sanctuary". In addition to the ruins, the sanctuary includes a large portion of the adjoining region, rich with the flora and fauna of the Peruvian Yungas and Central Andean wet puna ecoregions . Beyond its historical significance, Machu Picchu houses a diverse range of species. Among them are the Andean fox , puma , vizcacha, spectacled bear , and white-tailed deer. The sanctuary

372-472: A "summit," "peak," or "pyramid." Thus, the name of the site is often translated as "old mountain" or "old peak". Although the original name given to the settlement by its builders is not definitively known, a 2021 study in Ñawpa Pacha : Journal of the Institute of Andean Studies suggests that the site was likely called "Huayna Picchu," after the smaller peak nearby , or simply "Picchu." According to

496-403: A bottom layer of larger stones covered by loose gravel. On top of the gravel was a layer of mixed sand and gravel packed together, with rich topsoil covering it. Research showed that the topsoil was probably moved from the valley floor to the terraces because it was much better than the soil higher up the mountain. Little information exists surrounding human sacrifices at Machu Picchu, though it

620-464: A domestication of the wild rice Oryza rufipogon by cultures associated with pre-Austronesian and Hmong-Mien-speakers. This occurred 13,500 to 8,200 years ago south of the Yangtze River in present-day China. There are two likely centers of domestication for rice as well as the development of the wet-field technology. The first is in the lower Yangtze River , believed to be the homelands of

744-624: A family name. Many chose a name based on some geographical feature associated with their residence or occupation, and as nearly three-fourths of the population were farmers, many made family names using ta . Some common examples are Tanaka ( 田中 ), literally meaning "in the paddy field;" Nakata ( 中田 ), "middle paddy field;" Kawada (川田), "river paddy field;" and Furuta ( 古田 ), "old paddy field." In recent years, rice consumption in Japan has fallen and many rice farmers are increasingly elderly. The government has subsidized rice production since

868-559: A great deal of labor and materials to create and need large quantities of water for irrigation. Oxen and water buffalo , adapted for life in wetlands , are important working animals used extensively in paddy field farming. Paddy field farming remains the dominant form of growing rice in modern times. It is practiced extensively in Bangladesh , Cambodia , China , India , Indonesia , northern Iran , Japan , Laos , Malaysia , Mongolia , Myanmar , Nepal , North Korea , Pakistan ,

992-499: A newly irrigated paddy field, especially those made during or after the Edo period , may be called Nitta or Shinden (both 新田 ), "new paddy field." In some places, lakes and marshes were likened to a paddy field and were named with ta , like Hakkōda ( 八甲田 ). Today, many family names have ta as a component, a practice which can be largely attributed to a government edict in the early Meiji Period which required all citizens to have

1116-502: A pass and into the Pampaconas Valley where he found more ruins heavily buried in the jungle undergrowth at Espíritu Pampa , which he named "Trombone Pampa". As was the case with Machu Picchu, the site was so heavily overgrown that Bingham could only note a few of the buildings. In 1964, Gene Savoy further explored the ruins at Espiritu Pampa and revealed the full extent of the site, identifying it as Vilcabamba Viejo , where

1240-536: A possible environmental and commercial solution. The word "paddy" is derived from the Malay / Indonesian word padi , meaning "rice plant", which is itself derived from Proto-Austronesian *pajay ("rice in the field", "rice plant"). Cognates include Amis panay ; Tagalog pálay ; Kadazan Dusun paai ; Javanese pari ; and Chamorro faʻi , among others. Genetic evidence shows that all forms of paddy rice, including both indica and japonica , spring from

1364-505: A saddle between the two mountains Machu Picchu and Huayna Picchu, with a view down two valleys and a nearly impassable mountain at its back. The agricultural terraces, covering about 4.9 hectares (12 acres), complemented the site's architecture and protected against runoff and erosion. Constructed with stone retaining walls and well-drained topsoil, the terraces were built using deeper strata and stone chips to enhance drainage and ensure stability. Two high-altitude routes from Machu Picchu cross

1488-473: A sense, it has been unable to cope with population growth and other rice economies which utilized fertilizers. Rice is now grown in all the three seasons of Myanmar, though primarily in the Monsoon season – from June to October. Rice grown in the delta areas relies heavily on the river water and sedimented minerals from the northern mountains, whilst the rice grown in the central regions require irrigation from

1612-543: A similar process has begun with the introduction of smaller, lower-tech and much lower-priced 2WTs in the 4-9 horsepower range that can be safely operated in the small, narrow terraces, and are light enough to be lifted and lowered from one terrace to the next. What is different from the Alpine use is that these 2WTs are being used for tillage and crop establishment of maize , wheat, and potato crops, and with their small 60-70cm-wide rotovators and special cage wheels are puddling

1736-512: A study of the soil around the terraces showed that what was grown there was mostly corn and potatoes, which was not enough to support the 750+ people living at Machu Picchu. This explains why studies done on the food that the Inca ate at Machu Picchu suggest it was imported from the surrounding valleys and farther afield. It is estimated that the area around the site has received more than 1,800 mm (71 in) of rain per year since AD 1450, which

1860-735: A terrace was also called a "lynch" ( lynchet ). An example of an ancient Lynch Mill is in Lyme Regis . The water is directed from a river by a duct along a terrace. This set-up was used in steep hilly areas in the UK. Ancient terraces are a common feature in the Jerusalem Mountains , often found in conjunction with ancient rock-cut agricultural structures including quarries, winepresses, olive oil presses, water holes, lime kilns, roads, and agricultural watchtowers . According to Zvi Ron's estimation, these terraces encompass approximately 56% of

1984-507: A third entrance phase was added to better manage tourism and reduce site degradation. In 2024, the daily visitor limit was officially increased to 4,500, with up to 5,600 permitted during peak season. In May 2012, UNESCO urged additional protection measures for the site's buffer zone, especially due to the rapid growth in the nearby town of Aguas Calientes . Tourist deaths at Machu Picchu from altitude sickness , floods, and accidents have led to criticism of UNESCO for allowing visits despite

2108-578: Is a carved statue with a vaulted interior and carved drawings. It was used for rites or sacrifices. The Guardhouse is a three-sided building, with one of its long sides opening onto the Terrace of the Ceremonial Rock. The three-sided style of Inca architecture is known as the wayrona style. In 2005 and 2009, the University of Arkansas made detailed laser scans of the entire site and of

2232-478: Is also a luxury hotel on the mountain, near the ruins. Machu Picchu is officially twinned with Haworth , West Yorkshire in the United Kingdom, as well as Fukushima and Ōtama , Japan, Petra , Jordan, Medley , United States, and Tinum , Mexico. Machu Picchu is both a cultural and natural UNESCO World Heritage Site . Since Hiram Bingham's expedition, growing numbers of tourists have visited

2356-488: Is also habitat for more than 420 bird species, notably the cock-of-the-rock and the Andean condor . The surrounding environment features a variety of tree species such as alder, white cedar, husk, and laurel. In 1983, UNESCO designated Machu Picchu a World Heritage Site , describing it as "a masterpiece of art, urbanism, architecture and engineering" and "a unique testimony" of the Inca Civilization. Along

2480-737: Is archaeological evidence that unhusked rice was stored for the military and for burial with the deceased from the Neolithic period to the Han dynasty in China. By the late Neolithic (3500 to 2500 BC), population in the rice cultivating centers had increased rapidly, centered around the Qujialing - Shijiahe and Liangzhu cultures. There was also evidence of intensive rice cultivation in paddy fields as well as increasingly sophisticated material cultures in these two regions. The number of settlements among

2604-489: Is available, rice farmers typically plant Green Revolution rice varieties allowing three growing seasons per year. Since fertilizer and pesticide are relatively expensive inputs, farmers typically plant seeds in a very small plot. Three weeks following germination, the 15-20 centimetre (6–8 in) stalks are picked and replanted at greater separation, in a backbreaking manual procedure. Rice harvesting in Central Java

2728-401: Is characterized by steep slopes, dense vegetation, and significant rainfall, contributing to high humidity levels of 80–90%. The area is also frequently enveloped in cloud cover , typical of a cloud forest environment. The site is roughly divided into an urban sector and an agricultural sector, with the former divided between an upper town and a lower town. The temples are in the upper town,

2852-665: Is considered the main rice growing province of the Philippines . The Banaue Rice Terraces are an example of paddy fields in the country. They are located in Banaue in Northern Luzon , Philippines and were built by the Ifugaos 2,000 years ago. Streams and springs found in the mountains were tapped and channeled into irrigation canals that run downhill through the rice terraces. Other notable Philippine paddy fields are

2976-463: Is determined by the variety and quality control of water. The tavy is traditionally the culture of flooded upland rice on burning of cleared natural rain forest (135,966 ha). Criticized as being the cause of deforestation, tavy is still widely practiced by farmers in Madagascar, who find a good compromise between climate risks, availability of labour and food security. By extension,

3100-457: Is found in some place names, especially small farming townships and villages. However, the specific Korean term for 'paddy' is a purely Korean word, "non" ( Korean :  논 ). In Madagascar , the average annual consumption of rice is 130 kg per person, one of the largest in the world. According to a 1999 study of UPDRS / FAO: The majority of rice is related to irrigation (1,054,381 ha). The choice of methods conditioning performance

3224-580: Is grown in Northern Italy, especially in the valley of the Po River . The paddy fields are irrigated by fast-flowing streams descending from the Alps . In the 19th century and much of the 20th century, the paddy fields were farmed by the mondine , a subculture of seasonal rice paddy workers composed mostly of poor women. The acidic soil conditions common in Japan due to volcanic eruptions have made

3348-576: Is known that many sacrifices were never given a proper burial, and their skeletal remains succumbed to the elements. However, there is evidence that retainers were sacrificed to accompany a deceased noble in the afterlife. Animal, liquid and dirt sacrifices to the gods were more common and were made at the Altar of the Condor. The tradition is upheld by members of the New Age Andean religion . In

3472-549: Is literally an instrument or place to "tie up the sun", often expressed in English as "The Hitching Post of the Sun". The Inca believed the stone held the Sun in its place along its annual path in the sky. The stone is situated at 13°9'48" S. At midday on 11 November and 30 January, the Sun is situated almost exactly above the pillar, casting no shadow. On 21 June, the stone casts the longest shadow on its southern side, and on 21 December

3596-778: Is located in the Machupicchu District within the Urubamba Province above the Sacred Valley , which is 80 kilometers (50 mi) northwest of the city of Cusco . The Urubamba River flows past it, cutting through the Cordillera and creating a canyon with a subtropical mountain climate. The Inca civilization had no written language and following the first encounter by the Spanish soldier Baltasar Ocampo , no Europeans are recorded to have visited

3720-548: Is often performed not by owners or sharecroppers of paddies, but rather by itinerant middlemen, whose small firms specialize in the harvest, transport, milling, and distribution of rice. The fertile volcanic soil of much of the Indonesian archipelago—particularly the islands of Java and Bali—has made rice a central dietary staple. Steep terrain on Bali resulted in complex irrigation systems, locally called subak , to manage water storage and drainage for rice terraces. Rice

3844-463: Is possible that most of its inhabitants died from smallpox introduced by travelers before the Spanish conquistadors even arrived in the area. During its use as an estate, it is estimated that about 750 people lived there, with most serving as support staff ( yanaconas , yana) who lived there permanently. Though the estate belonged to Pachacutec, religious specialists and temporary specialized workers ( mayocs ) lived there as well, most likely for

3968-603: Is spreading across Nepal's Himalaya Mountains and likely into the other countries of the Himalaya and Hindu Kush . In the South American Andes , farmers have used terraces, known as andenes , for over a thousand years to farm potatoes, maize, and other native crops. Terraced farming was developed by the Wari culture and other peoples of the south-central Andes before 1000 AD, centuries before they were used by

4092-518: Is that Pachacutec ordered the construction of the royal estate for his use as a retreat, most likely after a successful military campaign. Although Machu Picchu is considered to be a "royal" estate, it would not have been passed down in the line of succession . Rather it was used for 80 years before being abandoned, seemingly because of the Spanish conquests in other parts of the Inca Empire . It

4216-626: Is the largest in the world, only about 15% of its total land area can be cultivated. About 75% of the cultivated area is used for food crops. Rice is China's most important crop, raised on about 25% of the cultivated area. Most rice is grown south of the Huai River , in the Yangtze valley, the Zhu Jiang delta, and in Yunnan , Guizhou , and Sichuan provinces. Rice appears to have been used by

4340-475: The Inca , who adopted them. The terraces were built to make the most efficient use of shallow soil and to enable irrigation of crops by allowing runoff to occur through the outlet. The Inca people built on these, developing a system of canals , aqueducts , and puquios to direct water through dry land and increase fertility levels and growth. These terraced farms are found wherever mountain villages have existed in

4464-887: The Comoros , and the coast of East Africa around the 1st millennium AD by Austronesian settlers from the Greater Sunda Islands . There are ten archaeologically excavated rice paddy fields in Korea. The two oldest are the Okhyun and Yaumdong sites, found in Ulsan , dating to the early Mumun pottery period . Paddy field farming goes back thousands of years in Korea. A pit-house at the Daecheon-ni site yielded carbonized rice grains and radiocarbon dates, indicating that rice cultivation in dry-fields may have begun as early as

4588-556: The Hellenistic period to Mamluk and Ottoman times. The majority of the samples fell within the latter periods. However, the study's ability to precisely determine the original construction date remains uncertain, as the results could also reflect subsequent agricultural modifications that affected exposure to sunlight.

4712-541: The Irrawaddy River . The fields are tilled when the first rains arrive – traditionally measured at 40 days after Thingyan , the Burmese New Year – around the beginning of June. In modern times, tractors are used, but traditionally, buffalos were employed. The rice plants are planted in nurseries and then transplanted by hand into the prepared fields. The rice is then harvested in late November – "when

Paddy fields can also be found on Malaysia's east coast region, in Kelantan and Terengganu . The central state of Selangor also has its fair share of paddy fields, especially in the districts of Kuala Selangor and Sabak Bernam . Before Malaysia became heavily reliant on its industrial output, people were mainly involved in agriculture, especially in

Most animal bones found were from llamas and alpacas . These animals naturally live at altitudes of 4,000 meters (13,000 ft) rather than the 2,400 meters (7,900 ft) elevation of Machu Picchu. Most likely, these animals were brought in from

5084-683: The Neolithic rice-farming cultures of the Yangtze River basin in southern China, associated with pre-Austronesian and Hmong-Mien cultures. It was spread in prehistoric times by the expansion of Austronesian peoples to Island Southeast Asia , Madagascar , Melanesia , Micronesia , and Polynesia . The technology was also acquired by other cultures in mainland Asia for rice farming, spreading to East Asia , Mainland Southeast Asia , and South Asia . Fields can be built into steep hillsides as terraces or adjacent to depressed or steeply sloped features such as rivers or marshes . They require

From Luzon, Austronesians rapidly colonized the rest of Maritime Southeast Asia , moving westwards to Borneo , the Malay Peninsula and Sumatra ; and southwards to Sulawesi and Java . By 500 BC, there is evidence of intensive wetland rice agriculture already established in Java and Bali , especially near very fertile volcanic islands. Rice did not survive

5456-522: The Puna region for meat consumption and for their pelts. Guinea pigs were also found at the site in special tomb caves, suggesting that they were at least used for funerary rituals, as it was common throughout the Inca Empire to use them for sacrifices and meat. Six dogs were also recovered from the site. Due to their placements among the human remains, it is believed that they served as companions of

It is 80 kilometers (50 miles) northwest of Cusco , on the crest of the mountain Machu Picchu, located about 2,430 meters (7,970 feet) above mean sea level , over 1,000 meters (3,300 ft) lower than Cusco, which has an elevation of 3,400 meters (11,200 ft). As such, it had a milder climate than the Inca capital. It is one of

5704-583: The Spring and Autumn period (722–481 BC), two revolutionary improvements in farming technology took place. One was the use of cast iron tools and beasts of burden to pull plows, and the other was the large-scale harnessing of rivers and development of water conservation projects. Sunshu Ao of the 6th century BC and Ximen Bao of the 5th century BC are two of the earliest hydraulic engineers from China, and their works were focused upon improving irrigation systems. These developments were widely spread during

Over the centuries, the surrounding jungle overgrew the site, and few outside the immediate area knew of its existence. The site may have been re-discovered and plundered in 1867 by a German businessman, Augusto Berns  [ de ] . Some evidence indicates that the German engineer J. M. von Hassel arrived earlier. Maps show references to Machu Picchu as early as 1874. A 1904 atlas designated

5952-523: The tanety , which literally means "hill," is also growing upland rice, carried out on the grassy slopes that have been deforested for the production of charcoal (139,337 ha). Among the many varieties, rice of Madagascar includes: Vary lava - a translucent long and large grain rice, considered a luxury rice; Vary Makalioka - a translucent long and thin grain rice; Vary Rojofotsy - a half-long grain rice; and Vary mena , or red rice, exclusive to Madagascar. Paddy fields can be found in most states on

Back in Cusco again, Bingham asked planters about the places mentioned by Calancha, particularly along the Urubamba River. According to Bingham, "one old prospector said there were interesting ruins at Machu Picchu," though his statements "were given no importance by the leading citizens." Only later did Bingham learn that Charles Wiener had also heard of

6448-647: The Austronesian voyages into Micronesia and Polynesia ; however, wet-field agriculture was transferred to the cultivation of other crops, most notably for taro cultivation. The Austronesian Lapita culture also came into contact with the non-Austronesian ( Papuan ) early agriculturists of New Guinea and introduced wetland farming techniques to them. In turn, they assimilated their range of indigenous cultivated fruits and tubers before spreading further eastward to Island Melanesia and Polynesia . Rice and wet-field agriculture were also introduced to Madagascar ,

6572-811: The Batad Rice Terraces, the Bangaan Rice Terraces, the Mayoyao Rice Terraces and the Hapao Rice Terraces. Machu Picchu Machu Picchu is a 15th-century Inca citadel located in the Eastern Cordillera of southern Peru on a mountain ridge at 2,430 meters (7,970 ft). Often referred to as the "Lost City of the Incas", it is the most familiar icon of the Inca Empire . It

6696-415: The Bay of Naples. Intensive terrace farming is believed to have been practiced before the early 15th century AD in West Africa . Terraces were used by many groups, notably the Mafa , Ngas , Gwoza , and the Dogon . It was long held that steep mountain landscapes are not conducive to, or do not even permit, agricultural mechanization. In the 1970s in the European Alps , pasture farms began mechanizing

6820-437: The Early Neolithic populations of Lijiacun and Yunchanyan in China. Evidence of possible rice cultivation from ca. 11,500 BC has been found, however it is still questioned whether the rice was indeed being cultivated, or instead being gathered as wild rice. Bruce Smith, an archaeologist at the Smithsonian Institution in Washington, D.C., who has written on the origins of agriculture, says that evidence has been mounting that

6944-569: The Early Mumun pottery period (c. 1100–850 BC). KUM has conducted excavations, that have revealed similarly dated paddy field features, at Yaeum-dong and Okhyeon, in modern-day Ulsan . The earliest Mumun features were usually located in low-lying narrow gullies, that were naturally swampy and fed by the local stream system. Some Mumun paddy fields in flat areas were made of a series of squares and rectangles, separated by bunds approximately 10 cm in height, while terraced paddy fields consisted of long irregular shapes that followed natural contours of

7068-582: The Incas fled after the Spanish drove them from Vitcos. Bingham returned to Machu Picchu in 1912 under the sponsorship of Yale University and National Geographic and with the full support of Peruvian President Augusto Leguia . The expedition undertook a four-month clearing of the site with local labor, which was expedited with the support of the Prefect of Cusco. Excavation started in 1912 with further excavation undertaken in 1914 and 1915. Bingham focused on Machu Picchu because of its fine Inca stonework and well-preserved nature, which had lain undisturbed since

7192-461: The Incas, the location of the city was a military secret, and its deep precipices and steep mountains provided natural defenses. The Inca Bridge , an Inca grass rope bridge , across the Urubamba River in the Pongo de Mainique , provided a secret entrance for the Inca army. Another Inca bridge was built to the west of Machu Picchu, the tree-trunk bridge, at a location where a gap occurs in the cliff that measures 6 meters (20 ft). The city sits in

7316-406: The Middle Jeulmun pottery period (c. 3500–2000 BC) in the Korean Peninsula . Ancient paddy fields have been carefully unearthed in Korea by institutes such as Kyungnam University Museum (KUM) of Masan . They excavated paddy field features at the Geumcheon-ni Site near Miryang , South Gyeongsang Province . The paddy field feature was found next to a pit-house that is dated to the latter part of

7440-553: The Monsoon . The paddy cultivation plays a major role in socio-cultural life of rural India. Many regional festivals celebrate the harvest, such as Onam , Bihu , Thai Pongal , Makar Sankranti , and Nabanna . The Kaveri delta region of Thanjavur is historically known as the rice bowl of Tamil Nadu , and Kuttanadu is called the rice bowl of Kerala . Gangavathi is known as the rice bowl of Karnataka .

Seligman suggested that while some terraces were established in ancient times, the majority of them are more likely to have originated during the Roman and Byzantine periods. A 2014 research study on terraces near Ramat Rachel , using Optically Stimulated Luminescence (OSL), yielded dates ranging from

7812-452: The Three Windows . The Popular District, or Residential District, is the place where the lower-class people lived. It includes storage buildings and simple houses. The royalty area, a sector for the nobility , is a group of houses located in rows over a slope; the residence of the amautas (wise people) was characterized by its reddish walls, and the zone of the ñustas (princesses) had trapezoid -shaped rooms. The Monumental Mausoleum

However, it is unknown if they had centralized control. In the terminal Neolithic (2500 to 2000 BC), Shijiahe shrank in size, and Liangzhu disappeared altogether. This is largely believed to be the result of the southward expansion of

8184-461: The Yangtze was probably the site of the earliest rice cultivation. In 1998, Crawford & Shen reported that the earliest of 14 AMS or radiocarbon dates on rice from at least nine Early to Middle Neolithic sites is no older than 7000 BC, that rice from the Hemudu and Luojiajiao sites indicates that rice domestication likely began before 5000 BC, but that most sites in China from which rice remains have been recovered are younger than 5000 BC. During

Such large-scale internal migration was possible due to introduction of quick-ripening strains of rice from Vietnam suitable for multi-cropping. Famous rice paddies in China include the Longsheng Rice Terraces and the fields of Yuanyang County, Yunnan . India has the largest paddy output in the world and is also the largest exporter of rice in

8432-542: The accusations, claiming that the excavation harmed the site and deprived local archaeologists of knowledge about their own history. Landowners began to demand rent from the excavators. By the time Bingham and his team left Machu Picchu, locals had formed coalitions to defend their ownership of Machu Picchu and its cultural remains, while Bingham claimed the artifacts ought to be studied by experts in American institutions. In 1981, Peru declared an area of 325.92 square kilometers (125.84 sq mi) surrounding Machu Picchu

8556-469: The archaeological site of Matsutaka in Mie Prefecture that dates to the late 2nd century. Ta ( 田 ) is used as a part of many place names as well as in many family names. Most of these places are somehow related to the paddy field and, in many cases, are based on the history of a particular location. For example, where a river runs through a village, the place east of the river may be called Higashida ( 東田 ), literally "east paddy field." A place with

Terracing is also used for sloping terrain; the Hanging Gardens of Babylon may have been built on an artificial mountain with stepped terraces, such as those on a ziggurat . At the seaside Villa of the Papyri in Herculaneum , the villa gardens of Julius Caesar 's father-in-law were designed in terraces to give pleasant and varied views of

9052-475: The constellations Llamacnawin, Llama, Unallamacha, Machacuay, and the star Pachapacariq Chaska ( Canopus ). The Intihuatana stone is a ritual stone which was used by the Incas. The stone is designed to point directly at the Sun during the winter solstice . The name of the stone (perhaps coined by Bingham) derives from Quechua language: inti means "sun", and wata- , "to tie, hitch (up)". The suffix -na derives nouns for tools or places. Hence Intihuatana

9176-448: The construction of Machu Picchu. Still visible are places where the terraces were shifted by landslides and then stabilized by the Inca as they continued to build around the area. The terraces also enabled irrigation, increasing crop yields, with maize likely being the main crop due to its ceremonial importance, alongside possible cultivation of potatoes. However, terrace farming area makes up only about 4.9 ha (12 acres) of land, and

9300-411: The dead. Much of the farming done at Machu Picchu was done on its hundreds of andenes (man-made terraces). These terraces were a work of considerable engineering, built to ensure good drainage and soil fertility while also protecting the mountain itself from erosion and landslides. However, the terraces were not perfect, as studies of the land show that there were landslides that happened during

9424-699: 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 . The spread of japonica rice cultivation and paddy field agriculture to Southeast Asia started with

9548-707: The eastern coast of Brazil , the Artibonite Valley in Haiti , Sacramento Valley in California , and West Lothian in Scotland among other places. Paddy cultivation should not be confused with cultivation of deepwater rice , which is grown in flooded conditions with water more than 50 cm (20 in) deep for at least a month. Global paddies' emissions account for at least 10% of global methane emissions . Drip irrigation systems have been proposed as

9672-636: The ensuing Warring States period (403–221 BC), culminating in the enormous Du Jiang Yan Irrigation System engineered by Li Bing by 256 BC for the State of Qin in ancient Sichuan . During the Eastern Jin (317–420) and the Northern and Southern Dynasties (420–589), land-use became more intensive and efficient, rice was grown twice a year and cattle began to be used for plowing and fertilization . By about 750, 75% of China's population lived north of

9796-635: The farmer to buy or grow rice seedlings. They are transplanted (usually by rice transplanter ) from the indoors into freshly flooded paddy fields in May. Farmers tend and weed their paddy fields through the summer until around the time of Chuseok , a traditional holiday held on 15 August of the Lunar Calendar (circa mid-September on the Solar Calendar). The harvest begins in October. Coordinating

9920-399: The harvest can be challenging because many Korean farmers have small paddy fields in a number of locations around their villages, and modern harvesting machines are sometimes shared between extended family members. Farmers usually dry the harvested grains in the sun before bringing them to market. The Hanja character for 'field', jeon ( Korean :  전 ; Hanja :  田 ),

10044-636: The land at various levels. Mumun Period rice farmers used all of the elements that are present in today's paddy fields, such as terracing, bunds, canals, and small reservoirs. We can grasp some paddy-field farming techniques of the Middle Mumun (c. 850–550 BC), from the well-preserved wooden tools excavated from archaeological rice fields at the Majeon-ni Site. However, iron tools for paddy-field farming were not introduced until sometime after 200 BC. The spatial scale of paddy-fields increased, with

10168-511: The last-known short-term diet for these people was overall composed of less fish and more corn. This suggests that several of the immigrants were from more coastal areas and moved to Machu Picchu where corn was a larger portion of food intake. Most skeletal remains found at the site had lower levels of arthritis and bone fractures than those found in most sites of the Inca Empire . Incan individuals who had arthritis and bone fractures were typically those who performed heavy physical labor (such as

10292-446: The late 16th century, Spaniards who had recently gained control of the area documented that indigenous individuals mentioned returning to "Huayna Picchu", the name that is believed to be originally given to the site by locals. The Spanish conquistador Baltasar de Ocampo had notes of a visit during the end of the 16th century to a mountain fortress called Pitcos with sumptuous and majestic buildings, erected with great skill and art, all

10416-638: The management of alpine pastures and harvesting of forage grasses through use of single axle two-wheel tractors (2WTs) and very low center of gravity articulated steering 4-wheel tractors. Their designs by various European manufacturers were initially quite simple but effective, allowing them to cross slopes approaching 20%. In the 2000s new designs of wheels and tires, tracks, etc, and incorporation of electronics for better and safer control, allowed these machines to operate on slopes greater than 20% with various implements such as reaper-harvesters, rakes, balers, and transport trailers. In Asian sub-tropical countries,

10540-572: The migrations of the Austronesian Dapenkeng culture into Taiwan between 3500 and 2000 BC. The Nanguanli site in Taiwan, dated to ca. 2800 BC, has yielded numerous carbonized remains of both rice and millet in waterlogged conditions, indicating intensive wetland rice cultivation and dryland millet cultivation. From about 2000 to 1500 BC, the Austronesian expansion began, with settlers from Taiwan moving south to migrate to Luzon in

10664-661: The most important archaeological sites in South America, one of the most visited tourist attractions in Latin America and the most visited in Peru. Machu Picchu is situated above a bow of the Urubamba River , which surrounds the site on three sides, where cliffs drop vertically for 450 meters (1,480 ft) to the river at their base. The area is subject to morning mists rising from the river. When inhabited by

10788-492: The mountains back to Cusco, one through the Sun Gate , and the other across the Inca bridge. Both could have been blocked easily, should invaders have approached along them. Machu Picchu and other sites in the area are built over earthquake faults . According to research conducted in 2019, this may not be a coincidence: "[o]ne simple answer, researchers now suggest, is that that's [earthquake faults] where building materials for

10912-553: The north to Kagoshima in the south, are slowly disappearing, but volunteers are helping the farmers both to maintain their traditional methods and for sightseeing purposes. Terraced fields are common in islands with steep slopes. The Canary Islands present a complex system of terraces covering the landscape from the coastal irrigated plantations to the dry fields in the highlands. These terraces, which are named cadenas (chains), are built with stone walls of skillful design, which include attached stairs and channels. In Old English ,

11036-547: The open grounds in the area. Despite their prevalence, there is a lack of consensus among scholars regarding their construction date. Various theories have been proposed, with Zvi Ron suggesting that their origins date back to ancient times, Finkelstein proposing the Middle Bronze Age , and Feig, Stager, and Harel suggesting the Iron Age . Archaeologists Gibson and Edelstein conducted research on terrace systems in

11160-419: The paddy field the most productive farming method. Paddy fields are represented by the kanji 田 (commonly read as ta or as den ) that has had a strong influence on Japanese culture. In fact, the character 田 , which originally meant 'field' in general, is used in Japan exclusively to refer to paddy fields. One of the oldest samples of writing in Japan is widely credited to the kanji 田 found on pottery at

11284-696: The pre-Austronesians and possibly also the Kra-Dai , and associated with the Kuahuqiao , Hemudu , Majiabang , Songze , Liangzhu , and Maquiao cultures . 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

11408-458: The preservation, management, and study of Machu Picchu. During the 2022–2023 Peruvian protests , routes to Machu Picchu were blocked, trapping thousands of tourists and leading to a government airlift of the stranded visitors. Due to these disruptions, the Ministry of Culture closed the site indefinitely on January 22, 2023, and it was reopened on February 15, 2023. Machu Picchu lies in

11532-641: The production of rice. It was for that reason, that people usually built their houses next to paddy fields. The very spicy chili pepper that is often eaten in Malaysia, the bird's eye chili , is locally called cili padi , literally "paddy chili". Some research pertaining to Rainfed lowland rice in Sarawak has been reported. Rice is grown in Myanmar primarily in three areas – the Irrawaddy Delta ,

11656-749: The regular use of iron tools, in the Three Kingdoms of Korea Period (c. AD 300/400-668). The first paddy fields in Japan date to the Early Yayoi period (300 BC – 250 AD). The Early Yayoi has been re-dated, and based on studies of early Japanese paddy formations in Kyushu it appears that wet-field rice agriculture in Japan was directly adopted from the Lower Yangtze river basin in Eastern China. Although China's agricultural output

11780-717: The research, the association of the name Machu Picchu with the ruins likely began with American explorer Hiram Bingham 's 1911 publications, a conclusion supported by Bingham’s field notes, early maps, and historical documents. Machu Picchu was previously believed (by Richard L. Burger , professor of anthropology at Yale University ) to have been built in the 1450s. However, a 2021 study led by Burger used radiocarbon dating (specifically, AMS ) to reveal that Machu Picchu may have been occupied from around 1420 to 1530 AD. Construction appears to date from two great Inca rulers, Pachacutec Inca Yupanqui (1438–1471) and Túpac Inca Yupanqui (1472–1493). A consensus among archaeologists

11904-655: The rice bends with age". Most of the rice planting and harvesting is done by hand. The rice is then threshed and stored, ready for the mills. In Nepal, rice (Nepali: धान, Dhaan) is grown in the Terai and hilly regions. It is mainly grown during the summer monsoon in Nepal . Paddy fields are a common sight in the Philippines. Several vast paddy fields exist in the provinces of Ifugao , Nueva Ecija , Isabela , Cagayan , Bulacan , Quezon , and other provinces. Nueva Ecija

12028-406: The ridge to the main ruins. The ruins were mostly covered with vegetation except for the cleared agricultural terraces and clearings used by the farmers as vegetable gardens. Because of the vegetation, Bingham was not able to observe the full extent of the site. He took preliminary notes, measurements, and photographs, noting the fine quality of Inca stonework of several principal buildings. Bingham

12152-622: The rock platform points out the Solstice Window to within 2' of the 15th century June solstice rising Sun. For comparison, the angular diameter of the Sun is 32'. The Inca constellation Qullca, storehouse, can be viewed out the Qullqa Window at sunset during the 15th-century June Solstice, hence the window's name. At the same time, the Pleaides are at the opposite end of the sky. Also seen through this window on this night are

12276-441: The ruins at Huayna Picchu and Machu Picchu, but was unable to reach them. Armed with this information, Bingham's expedition went down the Urubamba River . En route, Bingham asked local people to show them Inca ruins, especially any place described as having a white rock over a spring. At Mandor Pampa, Bingham asked farmer and innkeeper Melchor Arteaga if he knew of any nearby ruins. Arteaga said he knew of excellent ruins on

12400-513: The ruins at the top of the adjacent Huayna Picchu mountain. The scan data is available online for research purposes. This semicircular temple is built on the same rock overlying Bingham's "Royal Mausoleum", and is similar to the Temple of the Sun found in Cusco and the one found in Pisac , in having what Bingham described as a " parabolic enclosure wall". The stonework is of ashlar quality. Within

12524-849: The ruler's well-being and enjoyment. During the harsher season , staffing was reduced to a few hundred servants and a few religious specialists focused on maintenance alone. Studies show that, according to their skeletal remains, most people who lived there were immigrants from diverse backgrounds. They lacked the chemical markers and osteological markers they would have if they had been living there their entire lives. Instead, research into skeletal remains has found bone damage from various species of water parasites indigenous to different areas of Peru. There were also varying osteological stressors and varying chemical densities suggesting varying long-term diets characteristic of specific regions that were spaced apart. These diets are composed of varying levels of maize , potatoes , grains , legumes , and fish , but

12648-540: The site as Huayna Picchu. In 1911 American historian and explorer Hiram Bingham traveled the region looking for the lost capital of the Neo-Inca state (later established to be Vilcabamba ), established by Manco Inca after the Spanish conquest, and was led to Machu Picchu by a villager, Melchor Arteaga. Bingham found the name of the Peruvian explorer Agustín Lizárraga and the date 1902 written in charcoal on one of

12772-400: The site each year, with numbers exceeding 1.5 million in 2019. As Peru's most visited tourist attraction, and a major revenue generator, it is continually exposed to economic and commercial forces. In the late 1990s, the Peruvian government granted concessions to allow the construction of a cable car and a luxury hotel, including a tourist complex with boutiques and restaurants and a bridge to

12896-427: The site from the late 16th century until the 19th century. As far as historical knowledge extends, there are no existing written records detailing the site during its period of active use. The leading theory is that Machu Picchu was a private city for Incan royalty. The names of the buildings, their supposed uses, and their inhabitants, are the product of modern archaeologists based on physical evidence, including tombs at

13020-473: The site was abandoned. None of Bingham's several hypotheses explaining the site have since held up. During his studies, he carried various artifacts back to Yale. One prominent artifact was a set of 15th-century, ceremonial Incan knives made from bismuth bronze ; they are the earliest known artifact containing this alloy. Although local institutions initially welcomed the exploration, they soon accused Bingham of legal and cultural malpractice. Rumors arose that

13144-695: The site's high safety risks. The trend of nude tourism in 2014 also led to increased surveillance by Peru's Ministry of Culture to end the practice. In recognition of efforts to manage and protect the site, Fernando Astete, who served as Chief of the National Archaeological Park of Machu Picchu from 1994 to 2019, was honored with the "Personalidad Meritoria de la Cultura" award by the Ministry of Culture of Peru in January 2020. This award acknowledged his extensive contributions to

13268-489: The site, but the license was soon rescinded. In January 2010, severe flooding caused by El Niño trapped over 4,000 people and disrupted access to Machu Picchu, leading to its temporary closure. The site reopened on April 1, 2010. To further address tourism's impact, stricter entrance regulations were introduced in July 2011, limiting the number of daily visitors to 2,500 per day to the citadel and 400 to Huayna Picchu. In 2018,

13392-496: The site. These plans faced widespread protests, with critics arguing that the government had failed to conduct a proper environmental impact survey, as requested by the National Institute of Natural Resources , which warned of potential harm to the ecosystem. In 2018, plans were restarted to again construct a cable car to encourage Peruvians to visit Machu Picchu and boost domestic tourism. A no-fly zone exists above

13516-595: The site. Machu Picchu was built in the classical Inca style, with polished dry-stone walls . Its three primary structures are the Temple of the Sun , the Temple of the Three Windows, and the Intihuatana . From 1929 to 1971, Machu Picchu underwent extensive restoration and conservation work, including structural stabilization and artifact excavation, driven by government initiatives and research expeditions. Most recent archaeologists believe that Machu Picchu

13640-464: The site. The eastern section of the city was probably residential. The western, separated by the square, was for religious and ceremonial purposes. This section contains the Torreón , the massive tower which may have been used as an observatory . Located in the urban sector are the primary archaeological treasures and tourist attractions: the Intihuatana , the Temple of the Sun and the Temple of

13764-431: The site—large amounts of already fractured rock—were readily available." Between the valley floor and the altitudinal zone of the Inca citadel, ranging from 2,200 metres (7,200 ft) to 2,500 metres (8,200 ft) meters above sea level, the climate is warm and humid, with an average annual precipitation of 2,010 millimetres (79 in) and an annual mean temperature of approximately 18 °C (64 °F). The site

13888-652: The smaller peak of the same name. Machu Picchu was declared a Peruvian Historic Sanctuary in 1982 and a UNESCO World Heritage Site in 1983. In 2007, Machu Picchu was voted one of the New Seven Wonders of the World in a worldwide internet poll. The site is on a narrow saddle between two mountain peaks, Machu Picchu and Huayna Picchu. In the Quechua language , machu means "old" or "old person" and wayna means "young", while pikchu refers to

14012-445: The story, Lost City of the Incas (1952), Bingham claimed to have found the site himself. Though Bingham was not the first to visit the ruins, he was considered the scientific discoverer who brought Machu Picchu to international attention. Bingham organized another expedition in 1912 to undertake major clearing and excavation. Bingham was a lecturer at Yale University , although not a trained archaeologist. In 1909, returning from

14136-501: The team was stealing artifacts and smuggling them out of Peru through Bolivia . In fact, Bingham removed many artifacts, but openly and legally; they were deposited in the Yale University Museum. Bingham was abiding by the 1852 Civil Code of Peru; the code stated that "archaeological finds generally belonged to the discoverer, except when they had been discovered on private land" (Batievsky 100). Local press perpetuated

14260-414: The temple is a 1.2 m by 2.7 m rock platform, smooth on top except for a small platform on its southwest quadrant. A "Serpent's Door" faces 340°, or just west of north, opening onto a series of 16 pools, and affording a view of Huayna Picchu. The temple also has two trapezoidal windows, one facing 65°, called the "Solstice Window", and the other facing 132°, called the " Qullqa Window". The northwest edge of

14384-406: The terraces for transplanted and broadcast rice. Farmers are also using the engines as stationary power sources for powering water pumps and threshers . Even more recently farmers are experimenting with use of small reaper -harvester attachments. In Nepal, the low costs of these mostly Chinese-made machines and the increased productivity they produce have meant that this scale-appropriate machinery

14508-443: The top of Huayna Picchu. The next day, 24 July, Arteaga led Bingham and Sergeant Carrasco across the river on a log bridge and up the Machu Picchu site. At the top of the mountain, they came across a small hut occupied by a couple of Quechua people, Richard and Alvarez, who were farming some of the original Machu Picchu agricultural terraces that they had cleared four years earlier. Alvarez's 11-year-old son, Pablito, led Bingham along

14632-481: The walls of the Temple of the Three Windows. Initially disappointed, he documented in his pocket field journal: "Agustín Lizárraga is discoverer of Machu Picchu and lives at San Miguel Bridge just before passing." However, while Bingham initially acknowledged Lizárraga as the discoverer in his early writings and speeches, including Inca Land (1922), he gradually downplayed Lizárraga's role until, in his final version of

14756-424: The warehouses in the lower. The architecture is adapted to the mountains. Approximately 200 buildings are arranged on wide parallel terraces around an east–west central square. The various compounds, called kanchas , are long and narrow in order to exploit the terrain. Sophisticated channeling systems provided irrigation for the fields. Stone stairways set in the walls allowed access to the different levels across

14880-640: The west, and early Kra-Dai speakers to the south, facilitating the spread of rice cultivation throughout southern China. The earliest paddy field found dates to 4330 BC, based on carbon dating of grains of rice and soil organic matter found at the Chaodun site in Kunshan . At Caoxieshan, a site of the Neolithic Majiabang culture , archaeologists excavated paddy fields. Some archaeologists claim that Caoxieshan may date to 4000–3000 BC. There

15004-420: The world as of 2020. In India, West Bengal is the largest rice producing state. Paddy fields are a common sight throughout India, both in the northern Gangetic Plains and the southern peninsular plateaus. Paddy is cultivated at least twice a year in most parts of India, the two seasons being known as Rabi and Kharif respectively. The former cultivation is dependent on irrigation, while the latter depends on

15128-412: Was constructed as an estate for the Inca emperor Pachacuti (1438–1472). The Inca built the estate around 1450 but abandoned it a century later, at the time of the Spanish conquest . According to the new AMS radiocarbon dating , it was occupied from c. 1420–1532. Historical research published in 2022 claims that the site was probably called Huayna Picchu by the Inca people themselves, as it exists on

15252-416: Was more than that needed to support crop growth. Because of the ample rainfall at Machu Picchu, it was found that irrigation was not usually needed for the terraces. The terraces received so much rain that they were built by Incan engineers specifically to allow for drainage of excess water. Excavation and soil analyses done by Kenneth Wright in the 1990s showed that the terraces were built in layers, with

15376-560: Was unsure about the original purpose of the ruins, but concluded there was no indication that it matched the description of Vitcos. The expedition continued down the Urubamba and up the Vilcabamba Rivers examining all the ruins they could find. Guided by locals, Bingham rediscovered and correctly identified the site of the old Inca capital, Vitcos (then called Rosaspata), and the nearby temple of Chuquipalta . He then crossed
