Rice-duck Farming
Rice-duck farming is the polycultural practice of raising ducks and rice on the same land. It has existed in different forms for centuries in Asian countries including China, Indonesia, and the Philippines, sometimes also involving fish. The practice is beneficial as it yields harvests of both rice and ducks. The two are in addition synergistic, as the rice benefits from being weeded and fertilized by the ducks, and having pests removed, while the ducks benefit from the food available in the rice paddy fields, including weeds and small animals. Systems In 2010, Asia produced around 90% of the world's rice, and in 2012 some 80% of all duck meat. Asian farmers had a tradition of fattening ducks on rice paddies, though this was achieved in different ways. Integrated rice-duck farming uses hybrid ducks such as Aigamo that avoid eating the leaves of rice plants. Such mutually-beneficial polycultural systems have been described as permacultures. In 2001, rice-duck farming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Duck is the common name for numerous species of waterfowl in the family (biology), family Anatidae. Ducks are generally smaller and shorter-necked than swans and goose, geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch language, Dutch and German language, German 'to dive'.
