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] |
Ducks (6337601928)
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'. This word replaced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permaculture
Permaculture is an approach to land management and settlement design that adopts arrangements observed in flourishing natural ecosystems. It includes a set of design principles derived using Systems theory, whole-systems thinking. It applies these principles in fields such as regenerative agriculture, town planning, rewilding (conservation biology), rewilding, and community resilience. The term was coined in 1978 by Bill Mollison and David Holmgren, who formulated the concept in opposition to modern industrialized methods, instead adopting a more traditional or "natural" approach to agriculture. Multiple thinkers in the early and mid-20th century explored no-dig gardening, no-till farming, and the concept of "permanent agriculture", which were early inspirations for the field of permaculture. Mollison and Holmgren's work from the 1970s and 1980s led to several books, starting with ''Permaculture One'' in 1978, and to the development of the "Permaculture Design Course" which has ...

Agriculture In Asia
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than . However, five of every six farms in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Takao Furuno
Takao Furuno (born 1950) is a Japanese farmer, social entrepreneur, philanthropist, private aid volunteer, and pioneer of the duck-rice farming, known as ''aigamo'' in Japanese. Biography Born in 1950, Takao Furuno lives in Fukuoka Prefecture, Kyushu, Japan, a rural region west of the Japanese archipelago. A small farmer, he was one of the first to begin using organic farming methods in Japan, starting in 1978. By his account, he found in Rachel Carson’s famous book, ''Silent Spring'', the motivation to take his farm in a new direction. He obtained a PhD in Kyushu University. Evolution of the aigamo method After ten years of using organic farming practices, Furuno learned of a traditional Japanese rice farming method that consisted of using ducks to eliminate the weeds in rice fields, the "Aigamo Method." His first experiment was a success, but not without problems. In this system, ducklings are introduced into rice paddies for the purpose of (1) providing natural fe ...

Eutrophication
Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of organisms that may deplete the oxygen in the water; ie. the process of too many plants growing on the surface of a river, lake, etc., often because chemicals that are used to help crops grow have been carried there by rain. Eutrophication may occur naturally or as a result of human actions. Manmade, or cultural, eutrophication occurs when sewage, Industrial wastewater treatment, industrial wastewater, fertilizer runoff, and other nutrient sources are released into the environment. Such nutrient pollution usually causes algal blooms and bacterial growth, resulting in the depletion of dissolved oxygen in water and causing substantial environmental degradation. Many policies have been introduced to combat eutrophication, including the United Nations Development Program (UNDP)'s sustainability development goals. Approaches for prevention and re ...

Azolla
''Azolla'' (common called mosquito fern, water fern, and fairy moss) is a genus of seven species of aquatic ferns in the family Salviniaceae. They are extremely reduced in form and specialized, having a significantly different appearance to other ferns and more resembling some mosses or even duckweeds. '' Azolla filiculoides'' is one of two fern species for which a reference genome has been published. It is believed that this genus grew so prolifically during the Eocene (and thus absorbed such a large amount of carbon) that it triggered a global cooling event that has lasted to the present. ''Azolla'' may establish as an invasive plant in areas where it is not native. In such a situation, it can alter aquatic ecosystems and biodiversity substantially. Phylogeny Phylogeny of ''Azolla'' Other species include: At least six extinct species are known from the fossil record: *'' Azolla intertrappea'' Sahni & H.S. Rao, 1934 (Eocene, India) *'' Azolla berryi'' Brown, 1934 (Eocen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Planthopper
The brown planthopper (BPH), ''Nilaparvata lugens'' (Stål) (Hemiptera: Delphacidae) is a planthopper species that feeds on rice plants (''Oryza sativa'' L.). These insects are among the most important pests of rice, which is the major staple crop for about half the world's population. They damage rice directly through feeding and also by transmitting two viruses, rice ragged stunt virus and rice grassy stunt virus. Up to 60% yield loss is common in susceptible rice cultivars attacked by the insect. The BPH is distributed throughout Australia, Bangladesh, Bhutan, Burma (Myanmar), Cambodia, China, Fiji, India, Indonesia, Japan, North and South Korea, Laos, Malaysia, India, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand, and Vietnam. Their alternative host plant other than rice is '' Leersia hexandra''. Biology The brown planthopper is dimorphic, with fully winged 'macropterous' and truncate-winged 'brachypterous' forms. The macropterous forms are pote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthworm
An earthworm is a soil-dwelling terrestrial invertebrate that belongs to the phylum Annelida. The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta. In classical systems, they were in the order of Opisthopora since the male pores opened posterior to the female pores, although the internal male segments are anterior to the female. Theoretical cladistic studies have placed them in the suborder Lumbricina of the order Haplotaxida, but this may change. Other slang names for earthworms include "dew-worm", "rainworm", "nightcrawler", and "angleworm" (from its use as angling hookbaits). Larger terrestrial earthworms are also called megadriles (which translates to "big worms") as opposed to the microdriles ("small worms") in the semiaquatic families Tubificidae, Lumbricidae and Enchytraeidae. The megadriles are characterized by a distinct clitellum (more extensive than that of microdriles) and a vascular system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harvest
Harvesting is the process of collecting plants, animals, or fish (as well as fungi) as food, especially the process of gathering mature crops, and "the harvest" also refers to the collected crops. Reaping is the cutting of grain or pulses for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season. On large mechanized farms, harvesting uses farm machinery, such as the combine harvester. Automation has increased the efficiency of both the seeding and harvesting processes. Specialized harvesting equipment, using conveyor belts for gentle gripping and mass transport, replaces the manual task of removing each seedling by hand. The term "harvesting" in general usage may include immediate postharvest handling, including cleaning, sorting, packing, and cooling. The completion of harvesting marks the end of the growing season, or the growing cycle for a particular c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyculture
In agriculture, polyculture is the practice of growing more than one crop species together in the same place at the same time, in contrast to monoculture, which had become the dominant approach in developed countries by 1950. Traditional examples include the intercropping of the Three Sisters (agriculture), Three Sisters, namely maize, beans, and Cucurbita, squashes, by indigenous peoples of Central and North America, the rice-fish systems of Asia, and the complex mixed cropping systems of Nigeria. Polyculture offers multiple advantages, including increasing total yield, as multiple crops can be harvested from the same land, along with reduced risk of crop failure. Resources are used more efficiently, requiring less inputs of fertilizers and pesticides, as interplanted crops suppress weeds, and legumes can Nitrogen fixation, fix nitrogen. The increased diversity tends to reduce losses from Pest control, pests and plant diseases, diseases. Polyculture can yield multiple harvests ...

Rice Polyculture
Rice polyculture is the cultivation of rice and another crop simultaneously on the same land. The practice exploits the mutual benefit between rice and organisms such as fish and ducks: the rice supports pests which serve as food for the fish and ducks, while the animals' excrement serves as fertilizer for the rice. The result is an additional crop, with reduced need for inputs of fertilizer and pesticides. In addition, the reduction of pests such as mosquito larvae and snails may reduce mosquito-borne diseases such as malaria and dengue fever, and snail-born parasites such as the trematodes which cause schistosomiasis. The reduction in chemical inputs may reduce environmental harms caused by their release into the environment. The increased biodiversity may reduce methane emissions from rice fields. Some rice-animal polycultures, including rice-fish systems in China and rice-duck farming in China and Southeast Asia, have been practised for centuries, while others have been dev ...
