Red Rice Paddy

RED RICE PADDY 

A paddy field is a flooded parcel of  arable land  used for growing  semiaquatic   rice . 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. Genetic evidence shows that all forms of paddy rice, both indica and japonica, spring from a domestication of the wild rice  Oryza rufipogon  that first occurred 8,200–13,500 years ago South of the Yangtze River in present-day China. ^[1]  However, the domesticated indica subspecies currently appears to be a product of the introgression of favorable alleles from japonica at a later date, so that there are possibly several events of cultivation and domestication. ^[2]  Paddy fields are the typical feature of rice farming in  east ,  south  and  southeast Asia . Fields can be built into steep hillsides as  terraces  and adjacent to depressed or steeply sloped features such as rivers or  marshes . They can require 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.

During the 20th century, paddy-field farming became the dominant form of growing rice.  Hill tribes of Thailand  still cultivate dry-soil varieties called  upland rice . ^[3]  Paddy field farming is practiced in  Asia , namely in  Cambodia ,  Bangladesh ,  China ,  Taiwan ,  India ,  Indonesia ,  Iran ,  Japan ,  North Korea ,  South Korea ,  Malaysia ,  Myanmar ,  Nepal ,  Pakistan ,  Philippines ,  Sri Lanka ,  Thailand ,  Vietnam , and  Laos , and in  Europe ,  Northern Italy , the  Camargue  in  France , ^[4]  and in  Spain , particularly in the  Albufera de València  wetlands in the  Valencian Community , the  Ebro Delta  in  Catalonia  and the  Guadalquivir  wetlands in  Andalusia , as well as along the eastern coast of  Brazil , the  Artibonite Valley  in  Haiti , and  Sacramento Valley  in  California , among other places. Paddy fields are a major source of atmospheric methane and have been estimated to contribute in the range of 50 to 100 million tonnes of the gas per annum. ^{[5] [6]}  Studies have shown that this can be significantly reduced while also boosting crop yield by draining the paddies to allow the soil to aerate to interrupt methane production. ^[7]  Studies have also shown the variability in assessment of methane emission using local, regional and global factors and calling for better inventorisation based on micro level data. ^[8]

The word "paddy" is derived from the  Malay  word padi, rice plant. ^[9]

Archaeologists generally accept that wet-field cultivation originated in 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 County. ^[10]  At Caoxieshan, a site of the Neolithic  Majiabang culture , archaeologists excavated paddy fields. ^[11]  Some archaeologists claim that Caoxieshan may date to 4000–3000 BC. ^{[12] [13]}  There is archaeological evidence, that un husked  rice was stored for the military and for burial with the deceased, from the  Neolithic  period to the  Han Dynasty  in China. ^[14]

Korea

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 . ^[15]

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 the Middle  Jeulmun pottery period  (c. 3500–2000 BC) in the  Korean Peninsula . ^[16]  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 BC). KUM has conducted excavations, that have revealed similarly dated paddy field features, at Yaeum-dong and Okhyeon, in modern-day  Ulsan . ^[17]

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. ^{[18] [19]}

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 the regular use of iron tools, in the  Three Kingdoms of Korea  Period (c. AD 300/400-668).

Japan

The first paddy fields in Japan date to the Early  Yayoi period  [300 BC – 250 AD]. ^[20]  The Early Yayoi has been re-dated, and it appears that wet-field agriculture developed at about the same time as in the Korean peninsula.^{[ citation needed ]}

Philippines

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." ^[21]

Vietnam

Wet rice cultivation in Vietnam dates back to the  Neolithic  Hoa Binh culture and Bac Son culture. ^[22]

Although China's agricultural output 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 the Early  Neolithic  populations of Lijiacun and Yunchanyan in China. ^[24]  Evidence of possible rice cultivation from ca. 11,500 BP has been found, however it is still questioned whether the rice was indeed being cultivated, or instead being  gathered  as wild rice. ^[25]  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 the Yangtze was probably the site of the earliest rice cultivation. ^[26]  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. ^[24]

During 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. ^[27]  These developments were widely spread during 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 .

In circa 750, 75% of China's population lived north of the river  Yangtze , but by 1250, 75% of China's population lived south of the river Yangtze. Such large-scale internal migration was possible due to introduction of quick-ripening strains of rice from Vietnam suitable for multi-cropping. ^[28]

Localities in China which are famous for their spectacular rice paddies are  Yuanyang County, Yunnan , and  Longsheng County ,  Guangxi .

India

 

Paddy fields prior to planting in  Andhra Pradesh , India

India has the largest paddy output in the world and is also the fourth largest exporter of rice in the world. In India,  West Bengal  is the largest rice producing state. ^[29]  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 Monsoon. The paddy cultivation plays a major role in socio-cultural life of rural India. Many festivals such as Onam in  Kerala , Bihu in  Assam , Makara Sankranthi in  Andhra Pradesh ,  Thai Pongal In  Tamil Nadu ,  Makar Sankranti  in  Karnataka , Nabanna in  West Bengal  celebrates harvest of Paddy.  Kaveri  delta region of  Thanjavur  is historically known as the rice bowl of Tamil Nadu and  Kuttanadu  is called the rice bowl of Kerala.

Indonesia

 

Water buffalos  were formerly used to plough muddy paddy fields in Indonesia although the use of mechanised methods, such as small powered ploughs, has become much more common in recent years.

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 15-20 centimetre (6–8 in) 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 an intricate cooperation systems, locally called  subak , to manage water storage and drainage for rice terraces. ^[30]

Italy

Rice is grown in northern Italy, especially in the valley of the river  Po . ^[31]  The paddy fields are irrigated by fast-flowing streams descending from the  Alps .

Japan

 

Paddy field  scarecrows  in 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, which originally meant 'field' in general, is used in Japan exclusively to convey the meaning 'rice paddy field'. One of the oldest samples of writing in Japan is widely credited to the kanji 田 found on pottery at 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 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  which required all citizens to have 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 the 1970s, and favors  protectionist  policies regarding cheaper imported rice. ^[32]

Korea

 

Paddy field near  Namwon , South Korea, early June

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  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 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 ( Hangul : 전;  Hanja : 田), 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" ( Hangul : 논).

Madagascar

 

Baobab  and rice field near  Morondava , Madagascar

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 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.

"Tanety" means hill. By extension, the "tanety" is also growing upland rice, carried out on the grassy slopes have been deforested for the operation of charcoal. (139,337 ha)

Among the many varieties, rice of Madagascar include: "Vary lava" is a translucent long and large grain rice. It is a luxury ricer. "Vary Makalioka, is translucent long and thin grain rice. "Vary Rojofotsy" is a -half long.grain rice "Vary mena" or red rice, is exclusive to Madagascar.

Malaysia

Paddy field are typically found on  Peninsular Malaysia , in most of its regions. The most scenic paddy fields are located in northern Malaysia, in  Kedah ,  Perlis  and  Penang ; almost covering these states. Paddy fields also can be found on Malaysia's eastern coast region, mainly in  Kelantan  and  Terengganu , and also in  Selangor , 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 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".

Myanmar

Rice is grown primarily in three areas – the  Irrawaddy Delta , the area along and the delta of the  Kaladan River , and the Central plains around  Mandalay , though there has been an increase in rice farming in Shan State and Kachin State in recent years. ^[33]  Up until the later 1960s, Myanmar was the main exporter of rice. Termed the rice basket of South East Asia, much of the rice grown in Myanmar does not rely on fertilizers and pesticides, thus, although "organic" in 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 rely heavily on the river water and sedimented minerals from the northern mountains, whilst the rice grown in the central regions require irrigation from 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 the rice bends with age". Most of the rice planting and harvesting are done by hand. The rice is then threshed and stored, ready for the mills.

Philippines

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  is considered the main rice growing province of the  Philippines  and the leading producer of onions in the Municipality of Bongabon in  Southeast Asia . It is currently the 9th richest  province  in the country.

The  Banaue Rice Terraces  is an example of paddy fields in the country, it is located in Northern  Luzon , Philippines and were built by the  Ifugaos  2,000 years ago. ^[35]  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. ^[36]

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. ^[36]

Sri Lanka

Agriculture in Sri Lanka  mainly depends on rice production. ^[37]  Sri Lanka sometimes exports rice to its neighboring countries. Around 1.5 million hectares of land is cultivated in Sri Lanka for paddy in 2008/2009 maha: 64% of which is cultivated during the dry season and 35% cultivated during the wet season. Around 879,000 farmer families are engaged in paddy cultivation in Sri Lanka. They make up 20% of the country's population and 32% of the employment.

Rice production in Thailand  represents a significant portion of the  Thai economy . It uses over half of the farmable land area and labor force in Thailand. ^[38]

Thailand has a strong tradition of rice production. It has the fifth-largest amount of land under rice  cultivation  in the world and is the world's largest exporter of rice. ^[39]  Thailand has plans to further increase its land available for rice production, with a goal of adding 500,000  hectares  to its already 9.2 million hectares of rice-growing areas. ^[40]  The  Thai Ministry of Agriculture  expected rice production to yield around 30 million tons of rice for 2008. ^[41]  The most produced strain of rice in Thailand is  jasmine rice , which has a significantly lower  yield rate  than other types of rice, but also normally fetches more than double the price of other  strains  in a global market. ^[40]

Vietnam

 

A rice field in Vietnam

Rice fields in Vietnam (ruộng or cánh đồng in Vietnamese) are the predominant land use in the valley of the  Red River  and the  Mekong Delta . In the  Red River Delta  of northern Vietnam, control of seasonal riverine floodings is achieved by an extensive network of  dykes  which over the centuries total some 3000 km. In the  Mekong Delta  of southern Vietnam, there is an interlacing drainage and irrigation canal system that has become the symbol of this area. It jointly serves as transportation routes, allowing farmers to bring their produce to market. In Northwestern Vietnam,  Thai people  built their " valley culture " based on the cultivation of  glutinous rice  planted in upland fields, requiring terracing of the slopes.

The primary festival related to the agrarian cycle is "lễ hạ điền" (literally "descent into the fields") held as the start of the planting season in hope of a bountiful harvest. Traditionally, the event was officiated with much pomp. The monarch carried out the ritual plowing the first furrow while local dignitaries and farmers followed suit. Thổ địa (deities of the earth), thành hoàng làng (the village patron spirit),  Thần Nông  (god of agriculture), and thần lúa (god of rice plants) were all venerated with prayers and offerings.

In colloquial Vietnamese, wealth is frequently associated with the vastness of the individual's land holdings. Paddy fields so large as for "storks to fly with their wings out-stretched" ("đồng lúa thẳng cánh cò bay") can be heard as a common metaphor. Wind-blown undulating rice plants across a paddy field in literary Vietnamese is termed figuratively "waves of rice plants" ("sóng lúa").^{[ citation needed ]}
