A 'paddy field' is a flooded parcel of arable land used for growing rice and other semiaquatic crops. Rice can also be grown in dry-fields, but from the twentieth century paddy field agriculture became the dominant form of growing rice. Paddy fields are a typical feature of rice-growing countries of east and southeast Asia, including Malaysia, Nepal, China, Sri Lanka, Myanmar, Thailand, Korea, Japan, Vietnam, Taiwan, Indonesia, India, and the Philippines. They are also found in other rice-growing regions such as Piedmont (Italy), the Camargue (France) and the Artibonite Valley (Haiti).
Paddy fields can be built adjacent to otherwise natural areas such as rivers or marshes. They can be constructed, often on steep hillsides with much labor and materials. The fields require large quantities of water for irrigation. Flooding provides water essential to the growth of the crop. Water also provides a favorable environment for the rice strains being grown as well as discouraging the growth of many species of weeds. The water buffalo is the only draft animal adapted for life in wetlands so they are extensively used in paddy fields.
Growing rice has an adverse environmental impact because of the large quantities of methane gas it generates. World methane production due to paddy fields has been estimated to be in the range of 50 to 100 million tonnes per annum.^[1] This level of greenhouse gas generation is a large component of the global warming threat produced from an expanding human population. However, recent studies have shown that methane can be significantly reduced while also boosting crop yield by draining the paddies.^[2]
The word "paddy" is derived from the Malay word ''padi'', rice.^[3]

History

Archaeologists generally accept that wet-field cultivation originated in China, but as of now the oldest excavated rice paddies are from Korea^[4]. There 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.^[5]
Korean paddy-field farming is ancient. 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 the Middle Jeulmun Pottery Period (c. 3500-2000 B.C.) in the Korean Peninsula^[6]. 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 the Early Mumun Pottery Period (c. 1100-850 B.C.). KUM has conducted excavations that have revealed similarly dated paddy field features at Yaeum-dong and Okhyeon in modern-day Greater Ulsan^[7].
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 the land at various levels^[8][9].
Mumun Period rice farmers used all of the elements that are present in today's paddy fields such terracing, bunds, canals, and small reservoirs. We can grasp some paddy-field farming techniques of the Middle Mumun (c. 850-550 B.C.) 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 B.C. The spatial scale of paddy-fields increased with the regular use of iron tools in the Three Kingdoms of Korea Period (c. A.D. 300/400-668).
The first paddy fields in Japan date to the Early Yayoi period^[10]. The Early Yayoi has been re-dated and thus it appears that wet-field agriculture developed at approximately the same time as in the Korean peninsula.
In the Philippines, the use of rice paddies can be traced to prehistoric times, as evidenced in the names of towns such as Pila, Laguna, whose name can be traced to the straight mounds of dirt that form the boundaries of the rice paddy, or "Pilapil."

Wet rice cultivation in Vietnam dates back to the Neolithic Hoa Binh culture and Bac Son culture ^[11]

Culture

Indonesia

Prime Javanese paddy yields roughly 6 metric tons of unmilled rice (2.5 metric tons of milled rice) per hectare. When irrigation 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 6-8inch stalks are picked and replanted at greater separation, in a backbreaking manual procedure.
Rice harvesting in Central Java is often performed not by owners or sharecroppers of paddy, but rather by itinerant middlemen, whose small firms specialize in harvesting, transport, milling, and distribution to markets.
The fertile volcanic soil of much of the Indonesian archipelago-- and particularly the islands of Java and Bali-- has made rice a central dietary staple. Steep terrain on Bali resulted in intricate cooperation systems to manage water storage and drainage for rice terraces.^[12]

Italy

Rice is grown in northern Italy, especially in the valley of the river Po.^[13] The paddy fields are irrigated by fast-flowing streams descending from the Alps. Risotto, a rice dish flavoured with saffron is a typical dish from the rice-growing area near Milan that has now travelled around the world.

Japan

The acidic soil conditions common in Japan due to volcanic eruptions have made the paddy field the most productive farming method. Paddy fields are represented by the kanji 田 (commonly read as ''ta'') that has had a strong influence on Japanese culture. In fact, the character 田 means 'field' in Korean, but in Japan the same character is exclusively used to convey the meaning 'rice paddy field'. One of the oldest samples of writing is widely credited to the kanji 田 found on pottery at the archaeological site of Matsusaka, Mie 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 river may be called ''Higashida'' (東田), literally "east paddy field." A place with a newly irrigated paddy field, especially those during or later than 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 requiring all Japanese people to have a family name. Many chose a name based on or near the place they lived or the job they had, and with nearly three fourths of population being farmers, many made family names using ''ta''. Some common examples are ''Tanaka'' (田中) and ''Nakata'' (中田), literally meaning "middle of paddy field," ''Kawada'' (川田), "paddy field by a river," and ''Furuta'' (古田), "old paddy field."

Korea

Arable land in small alluvial flats of most rural river valleys in South Korea are dedicated to paddy-field farming. Farmers assess paddy fields for any necessary repairs in February. Fields may be rebuilt, and bund breaches are repaired. This work is carried out until mid-March, when warmer spring weather allows the farmer to buy or grow rice seedlings. They are transplanted (usually by hand) 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 August 15th of the Lunar Calendar (circa mid-September by Solar Calendar). The harvest begins in October. Coordinating 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 Chinese (or Sino-Korean) character for 'field', ''jeon'' (Hangeul: 전; Hanja: 田), is found in some place names, especially small farming townships and villages. However, the specific Korean term for 'paddy' is derived from Sino-Korean and is literally 'water-field' or ''sujeon'' (Hangeul: 수전; Hanja: 水田).

Philippines

Banaue rice terraces

The Banaue Rice Terraces are located in Northern Luzon 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 the Batad Rice Terraces, the Bangaan Rice Terraces, the Mayoyao Rice Terraces and the Hapao Rice Terraces.''Ifugao is Famous for...'', Wow Philippines, Tourism.gov.ph (undated), retrieved on: July 21, 2007
Located at Barangay Batad in Banaue, the Batad Rice Terraces are shaped like an amphitheatre, and can be reached by a 12-kilometer ride from Banaue Hotel and a 2-hour hike uphill through mountain trails. The Bangaan Rice Terraces portray the typical Ifugao community, where the livelihood activities are within the village and its surroundings. The Bangaan Rice Terraces is accessible in a one-hour ride from Poblacion, Banaue, then a 20-minute trek down to the village. It can be viewed best from the road to Mayoyao. The Mayoyao Rice Terraces is located at Mayoyao, 44 kilometers away from Poblacion, Banaue. The town of Mayoyao lies in the midst of these rice terraces. All dikes are tiered with flat stones. The Hapao Rice Terraces can be reached within 55 kilometers from the capital town of Lagawe. Other Ifugao stone-walled rice terraces are located in the municipality of Hungduan.

Vietnam

A rice field in Vietnam.

Rice fields in Vietnam (''ruộng'', ''cánh đồng'' or ''điền'' in Vietnamese) usually locate along Red river and Cửu Long river (a section of Mekong river). In Red river delta, farmers must dam up (nowadays 3000km long) against annual flood and that's also the neccessary condition to form an alliance among Vietnamese ancient tribals to found Vietnamese people's first state. In Cửu Long river delta, there's an interlacing drainage and irrigation canal system that becomes the symbol of this area and impacts on lifestyle of local people. In Northwestern area, Thai people built their ''"valley culture"'' based on economic foundation that's glutinous rice upland field.
Festival related to rice field is ''"lễ hạ điền"'' (Vietnamese)/''"lồng tồng"'' (Tay language) in the first day of every crop wishing for yield more than usual. In the past, it's the official national ceremony that the King would make the first plough and people would worship Shen Nong (god of agriculture), ''thổ địa'' (god of the soil), ''thành hoàng làng'' (god of the village) and ''thần lúa'' (god of rice plant).
In Trần dynasty, there're three kinds of rice field: ruộng quốc khố (national budget rice field) with 3 level, ruộng thác điền with 3 level (the name origins from a story about Lê Phụng Hiểu. He refused the King's present for his feat of arms but required that how far he would throw his knife, how wide of the rice field he could possess. Since then, it's become the name of rice field for rewarding Vietnamese mandarins: thác đao- abbreviation: thác- throw the knife and điền- rice field) and ruộng ao of common people.
In Vietnamese literature, the immensity of rice field's imagined that's wide enough for flock of stork can span their wings long: "''đồng lúa thẳng cánh cò bay''" and the sway lightly in the wind of rice plants compared with sea wave and called "''sóng lúa''". These describing forms're very popular and remind tranquil memmory about Vietnamese homeland.
