Monoculture is the agricultural practice of producing or growing a single crop, plant, or livestock species, variety, or breed in a field or farming system at a time. Polyculture, where more than one crop is grown in the same space at the same time, is the alternative to monoculture.[1] Monoculture is widely used in both industrial farming and organic farming and has allowed increased efficiency in planting and harvest while simultaneously increasing the risk of exposure to diseases or pests.

Continuous monoculture, or monocropping, where the same species is grown year after year,[2] can lead to the quicker buildup of pests and diseases, and then rapid spread where a uniform crop is susceptible to a pathogen. Monocultures of African palm oil,[3] sugar cane,[4] pines,[5] and soybeans[6] can all be particularly aggressive to environment. The practice has been criticized for its environmental effects and for having possible long term effects on agriculture and food supplies. Diversity can be added both in time, as with a crop rotation or sequence, or in space, with a polyculture.

Oligoculture has been suggested to describe a crop rotation of just a few crops, as is practiced by several regions of the world.[7]

The term is used in agriculture and describes the practice of planting the same cultivar over an extended area. Examples of monoculture include lawns and most fields of wheat or corn. The term is also used where a single breed of farm animal is raised in large-scale concentrated animal feeding operations (CAFOs). In the United States, The Livestock Conservancy was formed to protect nearly 200 endangered livestock breeds from going extinct, largely due to the increased reliance on just a handful of highly specialized breeds.

Rotation of polycultures Sequence of polycultures


In crop monocultures, each cultivar has the same standardized planting, maintenance and harvesting requirements resulting in greater yields and lower costs. For example, researchers have discovered a native plant to Senegal, called Guiera senegalensis, grown next to millet increased millet production roughly 900 percent. When a crop is matched to its well-managed environment, a monoculture can produce higher yields than a polyculture.[9] In the last 40 years, modern practices such as monoculture planting and the use of synthesized fertilizers have reduced the amount of additional land needed to produce food.[10]


Annually planting the same crop in the same area depletes the nutrients from the earth that the plant relies on and leaves soil weak and unable to support healthy growth.[11][12] Because soil structure and quality is so poor, farmers are forced to use chemical fertilizers to encourage plant growth and fruit production. These fertilizers, in turn, disrupt the natural makeup of the soil and contribute further to nutrient depletion. Monocropping also creates the spread of pests and diseases, which have to be treated with yet more chemicals. The effects of monocropping on the environment are severe when pesticides and fertilizers make their way into ground water or become airborne, creating pollution.[11][12] Polyculture, the mixing of different crops, reduces the likelihood that one or more of the crops will be resistant to any particular pathogen. Studies have shown that planting a mixture of crop strains in the same field can combat disease effectively.[13] Switching to polyculture in areas with disease conditions can greatly increased yields. In one study in China, the planting of several varieties of rice in the same field increased yields of non-resistant strains by 89% compared to non-resistant strains grown in monoculture, largely because of a dramatic (94%) decrease in the incidence of disease, making pesticides less necessary.[14]

Humans rely heavily on a relatively small number of food crops and farm animals for food. If disease hits a major food crop - as happened during the 19th-century Irish potato famine - food supplies for large populations could come under threat. Maintaining and increasing biodiversity in agriculture could help safeguard world food-supplies.[15]


In forestry, monoculture refers to the planting of one species of tree.[16] Monoculture plantings provide greater yields and more efficient harvesting than natural stands of trees. Single-species stands of trees are often the natural way trees grow, but the stands show a diversity in tree sizes, with dead trees mixed with mature and young trees. In forestry, monoculture stands that are planted and harvested as a unit provide limited resources for wildlife that depend on dead trees and openings, since all the trees are the same size; they are most often harvested by clearcutting, which drastically alters the habitat. The mechanical harvesting of trees can compact soils, which can adversely affect understory growth.[17] Single-species planting also causes trees to be more vulnerable when they are infected with a pathogen, or attacked by insects,[18] or affected by adverse environmental conditions.[19]

Genetic Monocultures

While often referring to the mass production of the same species of crop, it can also refer to planting of a single cultivar which has same identical genetic makeups to the plants around them. When all plants in a monoculture are genetically similar, a disease, to which they have no resistance, can destroy entire populations of crops. As of 2009 the wheat leaf-rust fungus occasioned a great deal of worry internationally, having already decimated wheat crops in Uganda and Kenya, and having started to make inroads into Asia as well.[20] Given the very genetically similar strains of much of the world's wheat crops following the Green Revolution, the impacts of such diseases threaten agricultural production worldwide.

Historic Examples of Monocultures

Irish Potato Famine

In Ireland, exclusive use of one variety of potato, the "lumper", led to the Great Famine of 1845-1849. Lumpers provided inexpensive food to feed the Irish masses. Potatoes were propagated vegetatively with little to no genetic variation. When Phytophthora infestans arrived in Ireland from the Americas in 1845, the lumper had no resistance to the disease, leading to the nearly complete failure of the potato crop across Ireland.


Until the 1950's, the Gros Michel cultivar of banana represented almost all bananas consumed in the United States because of their taste, small seeds, and efficiency to produce. Their small seeds, while more appealing than the large ones in other Asian cultivars, were not suitable for planting.[21] This meant that all new banana plants had to be grown from the cut suckers of another plant. As a result of this asexual form of planting, all bananas grown had identical genetic makeups which gave them no traits for resistance to Fusarium wilt, a fungal disease that spread quickly throughout the Caribbean where they were being grown. By the beginning of the 1960's, growers had to switch to growing the Cavedish banana, a cultivar grown in a similar way. This cultivar is under similar disease stress since all the bananas are clones of each other and could easily succumb as the Gros Michel did.[22]


Many of today's livestock production systems rely on just a handful of highly specialized breeds. Focusing heavily on a single trait (output) may come at the expense of other desirable traits - such as fertility, resistance to disease, vigor, and mothering instincts. In the early 1990s a few Holstein calves were observed to grow poorly and died in the first 6 months of life. They were all found to be homozygous for a mutation in the gene that caused Bovine Leukocyte Adhesion Deficiency. This mutation was found at a high frequency in Holstein populations worldwide. (15% among bulls in the US, 10% in Germany, and 16% in Japan.) Researchers studying the pedigrees of affected and carrier animals tracked the source of the mutation to a single bull that was widely used in the industry. Note that in 1990 there were approximately 4 million Holstein cattle in the US, making the affected population around 600,000 animals.[23]

Benefits of Genetic Diversity

While having little to no variety in the genetics of an agricultural system can have drawbacks, increasing genetic diversity by introducing organisms with varying genes can divert them and make the system more sustainable. For example, by having crops with varying genetic traits for disease and pest resistance, there is a much lower chance of having those pests or diseases spread throughout the area. This is because if one crop becomes infected with a particular strain of disease or species of pest, there is a chance that the other plants around it will have genes that protect them from that strain/species.[24] This can help increase crop productivity while simultaneously lowering pesticide usage and risk of exposure.


The environmental movement seeks to change popular culture by redefining the "perfect lawn" to be something other than a turf monoculture, and seeks agricultural policy that provides greater encouragement for more diverse cropping systems. Local food systems may also encourage growing multiple species and a wide variety of crops at the same time and same place. Heirloom gardening and raising heritage livestock breeds have come about largely as a reaction against monocultures in agriculture.

Agroecological restoration

Agroecological restoration is the practice of re-integrating natural systems into agriculture in order to maximize sustainability, ecosystem services, and biodiversity. This is one example of a way to apply the principles of agroecology to an agricultural system.

Anti-globalization movement

The anti-globalization movement, or counter-globalization movement, is a social movement critical of economic globalization. The movement is also commonly referred to as the global justice movement, alter-globalization movement, anti-globalist movement, anti-corporate globalization movement, or movement against neoliberal globalization.

Participants base their criticisms on a number of related ideas. What is shared is that participants oppose large, multinational corporations having unregulated political power, exercised through trade agreements and deregulated financial markets. Specifically, corporations are accused of seeking to maximize profit at the expense of work safety conditions and standards, labour hiring and compensation standards, environmental conservation principles, and the integrity of national legislative authority, independence and sovereignty. As of January 2012, some commentators have characterized changes in the global economy as "turbo-capitalism" (Edward Luttwak), "market fundamentalism" (George Soros), "casino capitalism" (Susan Strange), and as "McWorld" (Benjamin Barber).

Many anti-globalization activists do not oppose globalization in general and call for forms of global integration that better provide democratic representation, advancement of human rights, fair trade and sustainable development and therefore feel the term "anti-globalization" is misleading.

Appiko movement

Appu and mamtha started this movement in Gubbi Gadde, a small village near Sirsi in the (north) Uttara Kannada district, has forced the forest department to change the forest policy on felling of trees. Besides affecting the forest policy, it also spread to other parts and saved forests. On Sep.8, 1983, Pandurang Hegde, the fiery activist, started the Appiko (to hug) movement. He derived inspiration from Sunderlal Bahuguna's Chipko movement in Uttar Pradesh

, in which villagers used to hug trees to save them from being felled by the State, which then had no laws against felling of timber inside protected areas. Appiko movement was started against monoculture (the agricultural practice of producing or growing one single crop over a wide area) in the western ghats. Today, it has become a part of the lives of people. Their non-violent protest movement has compelled the forest department to amend the policy against felling of forests in eco-sensitive region. There has been a silent revolution in the Western Ghats.

Panduranga Hegde, the founder of Appiko Movement says that this movement has become a part of the culture in the western ghats and has saved the very sensitive eco sphere. "This movement, started to protest against felling of trees, monoculture, forest policy and deforestation, has succeeded in changing the forest policy. This first ever people's green movement in south India to save our natural resources has become a model of sustainable development," said Panduranga Hedge, the founder of Appiko movement. "The activists used local folklore to reach out to the masses. Another activist and farmer Mahabaleshwara Hegde of Gubbi gadde village finds this movement a part of the lives of people in this area. The Gandhi of environmental movement, Sunderlal Bahuguna, not only inspired the movement but visits here regularly to guide the people," Hedge added. Mahabaleshwara Hegde, said: "The river Kali meanders through the valley linking the past and the present. The song of Apppiko reverberates in the hills. The 35-year-old movement, reminds the people of the need to conserve sensitive eco sphere. In 1983, the villagers in Sirsi taluka of North Kanara district launched an 'embrace the trees' campaign." In 1950, forests covered more than 81 percent of the geographical area in Uttara Kannada (or North Kanara) district. But being declared a 'backward' district, the area was selected for major industries—a pulp and paper mill, a plywood factory and a chain of hydroelectric dams constructed to harness the rivers. By 1980, forest in the district was believed to have shrunk to 25 per cent. Locals, especially the poor, were displaced by dams. Environmentalists blamed monoculture for drying up water sources, affecting forest-dwellers. Started in Sirsi, the Appiko movement spread across the western Ghats, including in places outside Karnataka. By linking up, campaigners managed to build awareness to conserve the sensitive environment in this region. Appiko is seen by some as a kind of echo of the more prominent Chipko movement of north India.

Cultural diversity

Cultural diversity is the quality of diverse or different cultures, as opposed to monoculture, the global monoculture, or a homogenization of cultures, akin to cultural decay. The phrase cultural diversity can also refer to having different cultures respect each other's differences. The phrase "cultural diversity" is also sometimes used to mean the variety of human societies or cultures in a specific region, or in the world as a whole. Globalization is often said to have a negative effect on the world's cultural diversity.

Cultural globalization

Cultural Globalization refers to the transmission of ideas,

meanings, and values around the world in such a way as to extend and intensify social relations. This process is marked by the common consumption of cultures that have been diffused by the Internet, popular culture media, and international travel. This has added to processes of commodity exchange and colonization which have a longer history of carrying cultural meaning around the globe. The circulation of cultures enables individuals to partake in extended social relations that cross national and regional borders. The creation and expansion of such social relations is not merely observed on a material level. Cultural globalization involves the formation of shared norms and knowledge with which people associate their individual and collective cultural identities. It brings increasing interconnectedness among different populations and cultures.

Elsick Mounth

The Elsick Mounth is an ancient trackway crossing the Grampian Mountains in the vicinity of Netherley, Scotland. This trackway was one of the few means of traversing the Grampian Mounth area in prehistoric and medieval times. The highest pass of the route is attained within the Durris Forest. Notable historical structures in the vicinity are Maryculter House, Lairhillock Inn and Muchalls Castle. Most of the lands through which the Elsick Mounth passes are within the Durris Forest; while this forest would have been a mixed deciduous forest in ancient times, currently it is managed as a coniferous monoculture with extensive amounts of clearfelling and subsequent replanting.


Hand pollination, also known as mechanical pollination is a technique that can be used to pollinate plants when natural or open pollination is either undesirable or insufficient. This method of pollination is done by manually transferring pollen from the stamen of one plant to the pistil of another. This is often done with a cotton swab or small brush, but can also be done by removing the petals from a male flower and brushing it against the stigmas of female flowers, or by simply shaking flowers in the case of bisexual flowers, such as tomatoes. Common reasons for choosing this method include the lack of pollinators, keeping control of cross-pollination between varieties grown together, and creating specific hybrids. Examples of this are vanilla plants, which are transported to areas where its natural pollinator doesn't exist, or plants grown in greenhouses, urban areas, or with a cover to control pests, where natural pollinators cannot reach them. Pollinator decline and the concentrated pollination needs of monoculture can also be a factor. However, these are not the only reasons, and variable techniques for hand-pollination have arisen for many specialty crops. For instance, hand-pollination is used with date palms to avoid wasting space and energy growing sufficient male plants for adequate natural pollination. Because of the level of labor involved, hand-pollination is only an option on a small scale, used chiefly by small market gardeners and owners of individual plants. On large-scale operations, such as field crops, orchards, or commercial seed production, honeybees or other pollinators are a more efficient approach to pollination management. Despite this, hand-pollination is a fairly widespread practice. Pears grown in Hanyuan County, China have been hand-pollinated since the 1980s, because they can't be pollinated with other varieties that have different flowering times; also, lice infestation requires the use of many insecticide sprays, which causes local beekeepers to refuse to lend beehives.

Karakum Canal

The Karakum Canal (Qaraqum Canal, Kara Kum Canal, Garagum Canal; Russian: Каракумский канал, Karakumskiy Kanal, Turkmen: Garagum kanaly, گَرَگوُم كَنَلیٛ‎, Гарагум каналы) in Turkmenistan is one of the largest irrigation and water supply canals in the world. Started in 1954, and completed in 1988, it is navigable over much of its 1,375-kilometre (854 mi) length, and carries 13 cubic kilometres (3.1 cu mi) of water annually from the Amu-Darya River across the Karakum Desert in Turkmenistan. The canal opened up huge new tracts of land to agriculture, especially to cotton monoculture heavily promoted by the Soviet Union, and supplying Ashgabat with a major source of water. The canal is also a major factor leading to the Aral Sea environmental disaster.


Lygodium (climbing fern) is a genus of about 40 species of ferns, native to tropical regions across the world, with a few temperate species in eastern Asia and eastern North America. It is the sole genus in the family Lygodiaceae, though included in the family Schizaeaceae by some botanists.

They are unusual in that the rachis, or midrib, of the frond is thin, flexible, and long, the frond unrolling with indeterminate growth and the rachis twining around supports, so that each frond forms a distinct vine. The fronds may be from 3–12 m (9.8–39.4 ft) long, depending on the species.Some Lygodium species are now considered very problematic invasive weeds in the southeastern United States. Populations of Lygodium have increased more than 12-fold over the past decade, as noted by Florida's Institute of Food and Agricultural Sciences.Japanese climbing fern (Lygodium japonicum) was added to the Florida Noxious Weed List in 1999. It is also a major problem in pine plantations, causing contamination and harvesting problems for the pine straw industry. Old World climbing fern (Lygodium microphyllum) infests cypress swamps and other hydric sites, forming a monoculture. This massive infestation displaces all native flora and fauna, completely changing the ecosystem of the area.Plants in this genus have basal chromosome counts of n=28, 29, 30.

Monoculture (album)

Monoculture is the debut studio album by American indie rock band Sainthood Reps. It was produced by Mike Sapone and released on August 9, 2011, by Tooth & Nail Records.

Monoculture (computer science)

In computer science, a monoculture is a community of computers that all run identical software. All the computer systems in the community thus have the same vulnerabilities, and, like agricultural monocultures, are subject to catastrophic failure in the event of a successful attack.

The concept is significant when discussing computer security and viruses. Clifford Stoll wrote in 1989 after dealing with the Morris worm:

A computer virus is specialized: a virus that works on an IBM PC cannot do anything to a Macintosh or a Unix computer. Similarly, the Arpanet virus could only strike at systems running Berkeley Unix. Computers running other operating systems—like AT&T Unix, VMS, or DOS—were totally immune.

Diversity, then, works against viruses. If all the systems on the Arpanet ran Berkeley Unix, the virus would have disabled all fifty thousand of them. Instead, it infected only a couple thousand. Biological viruses are just as specialized: we can't catch the flu from dogs.

Bureaucrats and managers will forever urge us to standardize on a single type of system: "Let's only use Sun workstations" or "Only buy IBM systems." Yet somehow our communities of computers are a diverse population—with Data General machines sitting next to Digital Vaxes; IBMs connected to Sonys. Like our neighborhoods, electronic communities thrive through diversity.

Dan Geer has argued that Microsoft is a monoculture, since a majority of the overall number of workstations connected to the Internet are running versions of the Microsoft Windows operating system, many of which are vulnerable to the same attacks.


Pascopyrum is a monotypic genus of grass containing the sole species Pascopyrum smithii, which is known by the common name western wheatgrass, though the common nickname is red-joint wheatgrass, from the red coloration of the nodes. This is a sod-forming rhizomatous perennial grass which is native and common throughout most of North America. It grows in grassland and prairie in the Great Plains, where it is sometimes the dominant grass species. It is the state grass of North Dakota, South Dakota, and Wyoming.

It is a valuable forage for animals such as bison and black-tailed prairie dogs, and it is good for grazing livestock. It is used for revegetation of disturbed and overgrazed habitat, and many cultivars have been developed to suit various conditions, including low-maintenance lawns. Wheatgrass generally tolerates mowing to four inches, but does not tolerate shade. Healthy stands may crowd out other species, making it more suitable for monoculture plantings.

Pilar, Sorsogon

Pilar, officially the Municipality of Pilar, is a 1st class municipality in the province of Sorsogon, Philippines. According to the 2015 census, it has a population of 74,564 people.Pilar's economy is mainly agricultural. Despite efforts on multiplicity, this town is still dependent on the monoculture of coconut.


Polyculture is a form of agriculture in which more than one species is grown at the same time and place in imitation of the diversity of natural ecosystems. Polyculture is the opposite of monoculture, in which only members of one plant or animal species are cultivated together. Polyculture has traditionally been the most prevalent form of agriculture in most parts of the world and is growing in popularity today due to its environmental and health benefits. There are many types of polyculture including annual polycultures such as intercropping and cover cropping, permaculture, and integrated aquaculture. Polyculture is advantageous because of its ability to control pests, weeds, and disease without major chemical inputs. As such, polyculture is considered a sustainable form of agriculture. However, issues with crop yield and biological competition have caused many modern major industrial food producers to continue to rely on monoculture instead.


Pulpwood refers to timber with the principal use of making wood pulp for paper production.

Rubber tapping

Rubber tapping is the process by which latex is collected from a rubber tree. The latex is harvested by slicing a groove into the bark of the tree at a depth of a quarter inch with a hooked knife and peeling back the bark. Trees must be approximately six years old and six inches in diameter in order to be tapped for latex. Rubber Tapping is not damaging to the forest, as it does not require the tree to be cut down in order for the latex to be extracted. Jungle rubber is essentially old secondary forest, strongly resembling the primary forest. Its species' richness is about half that of the primary forest. Michon and de Foresta (1994) found that sample jungle rubber sites contained 92 tree species, 97 lianas, and 28 epiphytes compared with 171, 89, and 63, respectively, in the primary forest, and compared with 1, 1, and 2 in monoculture estates. Thiollay (1995) estimated that jungle rubber supports about 137 bird species, against 241 in the primary forest itself. Jungle rubber is expected to resemble primary forest in its hydrological functions. Mono culture rubber tree plantations have far less of an environmental impact than other crops, such as coffee or especially oil palm.

Sainthood Reps

Sainthood Reps is an American indie rock band from Long Island, New York, formed in 2009. Their debut album, Monoculture, was released on Tooth & Nail Records in the summer of 2011 and was produced by Mike Sapone. The band released their second album, Headswell, in October 2013 through No Sleep Records.

Shade-grown coffee

Shade-grown coffee is a form of the beverage produced from coffee plants grown under a canopy of trees. A canopy of assorted types of shade trees is created to cultivate shade-grown coffee. Because it incorporates principles of natural ecology to promote natural ecological relationships, shade-grown coffee can be considered an offshoot of agricultural permaculture or agroforestry. The resulting coffee is usually sold as "shade-grown".

World government

World government or global government or cosmocracy is the notion of a common political authority for all of humanity, giving way to a global government and a single state that exercises authority over the entire world. Such a government could come into existence either through violent and compulsory world domination or through peaceful and voluntary supranational union.

There has never been a worldwide executive, legislature, judiciary, military, or constitution with global jurisdiction. The United Nations, beyond the United Nations Security Council (which has the ability to issue mandatory resolutions), is limited to a mostly advisory role, and its stated purpose is to foster cooperation between existing national governments rather than exert authority over them.
