A '''paddy field''' is a flooded parcel of [[arable land]] used for growing [[rice]] and other [[Aquatic plant|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 Asia|east]], [[South Asia|south]] and [[southeast Asia]], including [[Cambodia]], [[Bangladesh]], [[People's Republic of China|China]], [[India]], [[Indonesiaඉන්දුනීසියාව]], [[Japan]], [[Korea]], [[Malaysia]], [[Myanmar]], [[Nepal]], [[Pakistan]], the [[Philippines]], [[Sri Lanka]], [[Taiwan]], [[Thailand]], and [[Vietnam]]. They are also found in other rice-growing regions such as [[Piedmont]] (Italy), the [[Camargue]] (France) and the [[Artibonite]] Valley (Haiti), and the remains of rice paddies still define much of landscape of the [[Carolina Lowcountry]].
 
Paddy fields can be built adjacent to otherwise natural areas such as [[river]]s or [[marshes]]. They can be constructed, often on steep hillsides with much [[manual labour|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 [[weed]]s. The [[Domestic buffalo|water buffalo]] is the only [[working animal]] adapted for life in [[wetlands]] so they are extensively used in paddy fields.

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 [[sharecropper]]s 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 [[Indonesiaඉන්දුනීසියාව]]n 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, locally called ''[[Subak (irrigation)|subak]]'', to manage water storage and drainage for rice terraces.<ref>[http://www.santafe.edu/research/publications/workingpapers/03-05-030.pdf Lansing and Miller]</ref>
