The quinoa [[monoculture]] that arose from increased production, combined with [[climate change]] effects in the native Andean region, created challenges for production and yield, and led to [[environmental degradation]].

== Description ==
[[File:QuinoaGrains.jpg|thumb|Quinoa seeds]]''Chenopodium quinoa'' is a [[dicotyledon]]ous [[annual plant]], usually about {{cvt|1|–|2|m|ft|0}} high. It has broad, generally powdery, hairy, lobed leaves, normally arranged [[Alternate leaf|alternately]]. The woody central [[plant stem|stem]] is branched or unbranched depending on the variety and may be green, red or purple. The flowering [[panicle]]s arise from the top of the plant or from [[leaf axils]] along the stem. Each panicle has a central axis from which a secondary axis emerges either with flowers (amaranthiform) or bearing a tertiary axis carrying the flowers (glomeruliform).<ref name="Lost crops"/> These are small, incomplete, sessile flowers of the same colour as the sepals, and both pistillate and perfect forms occur. Pistillate flowers are generally located at the proximal end of the glomeruli and the perfect ones at the distal end of it. A perfect flower has five sepals, five anthers and a superior ovary, from which two to three stigmatic branches emerge.<ref>{{cite journal |last1=Bertero |first1=Daniel |last2=Medan |first2=Diego |last3=Hall |first3=A.

In regards to the "newly" developed salinity resistance of ''C.{{nbsp}}quinoa'', some studies have concluded that accumulation of organic osmolytes plays a dual role for the species. They provide osmotic adjustment, in addition to protection against oxidative stress of the photosynthetic structures in developing leaves. Studies also suggested that reduction in stomatal density in reaction to salinity levels represents an essential instrument of defence to optimize water use efficiency under the given conditions to which it may be exposed.<ref>{{cite journal |last1=Shabala |first1=Lana |last2=Mackay |first2=Alex |last3=Tian |first3=Yu |last4=Jacobsen |first4=Sven-Erik |last5=Zhou |first5=Daowei |last6=Shabala |first6=Sergey |date=September 2012 |title=Oxidative stress protection and stomatal patterning as components of salinity tolerance mechanism in quinoa (''Chenopodium quinoa'') |journal=Physiologia Plantarum |volume=146 |issue=1 |pages=26–38 |doi=10.1111/j.1399-3054.2012.01599.x |pmid=22324972|bibcode=2012PPlan.146...26S }}</ref>

== Taxonomy ==
The species ''Chenopodium quinoa'' was first described by [[Carl Ludwig Willdenow]] (1765–1812),{{sfn|Linné|Willdenow|1797|p=1301}} a German botanist who studied plants from South America, brought back by explorers [[Alexander von Humboldt]] and [[Aimé Bonpland]].

Quinoa is an [[allotetraploid]] plant, containing two full sets of [[chromosome]]s from two different species which hybridised with each other at one time. According to a 1979 study, its presumed ancestor is either ''[[Chenopodium berlandieri]]'', from North America, or the Andean species ''Ch. hircinum'', although more recent studies, in 2011, even suggest Old World relatives. On the other hand, morphological features relate ''Ch.{{nbsp}}quinoa'' of the Andes and [[Chenopodium nuttalliae|''Ch. nuttalliae'']] of Mexico. Some studies have suggested that both species may have been derived from the same wild type. A weedy quinoa, ''Ch.{{nbsp}}quinoa'' var. ''melanospermum'', is known from South America, but no equivalent closely related to ''Ch.{{nbsp}}nutalliae'' has been reported from Mexico so far.<ref name="Bazile2014" />

Studies regarding the genetic diversity of quinoa suggest that it may have passed through at least three bottleneck genetic events, with a possible fourth expected:
*The first occurred when the species was created, as its two [[diploid]] ancestors underwent a hybridization followed by chromosome doubling, this new species was genetically isolated from its parent species, and thus lost a great deal of genetic diversity. These ancestors are still not known, but are ''not'' the higher altitude crop species ''[[Chenopodium pallidicaule]]'' (cañahua), a diploid.<ref>{{cite journal |last1=Mangelson |first1=Hayley |last2=Jarvis |first2=David E. |last3=Mollinedo |first3=Patricia |last4=Rollano-Penaloza |first4=Oscar M. |last5=Palma-Encinas |first5=Valeria D. |last6=Gomez-Pando |first6=Luz Rayda |last7=Jellen |first7=Eric N. |last8=Maughan |first8=Peter J. |year=2019 |title=The genome of ''Chenopodium pallidicaule'': An emerging Andean super grain |journal=Applications in Plant Sciences |volume=7 |issue=11 |pages=e11300 |doi=10.1002/aps3.11300 |pmc=6858295 |pmid=31832282|bibcode=2019AppPS...7E1300M }}</ref>
*A second bottleneck may have occurred when quinoa was domesticated from its unknown but possible wild [[tetraploid]] form. It might have been domesticated twice: once in the high Andes and a second time in the Chilean and Argentinean lowlands.
*A third bottleneck can be considered "political", and has lasted more than 400&nbsp;years, from the Spanish conquest of the new continent until the present time. During this phase quinoa has been replaced with [[maize]], marginalized from production processes possibly due to its important medicinal, social and religious roles for the indigenous populations of South America, but also because it is very difficult to process (dehusk) compared with maize.
*In the 21st century, a fourth bottleneck event may occur, as traditional farmers migrate from rural zones to urban centers, which exposes quinoa to the risk of further [[genetic erosion]]. Better breeding may also result in loss of genetic diversity, as breeders would be expected to reduce unwanted alleles to produce uniform cultivars, but cross-breeding between local landraces has and will likely produce high-diversity cultivars.<ref name="Bazile2014" />

=== Etymology ===
The genus name ''Chenopodium'' is composed of two words coming from the Greek χήν,-νός, ''goose'' and πόδῖον, ''podion'' "little foot", or "goose foot", because of the resemblance of the leaves with the trace of a goose's foot.{{sfn|Bailly|1935|p=2136}}

The [[specific epithet (botany)|specific epithet]] ''quinoa'' is a borrowing from the Spanish ''quinua'' or ''quinoa'', itself derived from [[Quechuan languages|Quechua]] ''kinuwa''.

The [[Inca Empire|Incas]] nicknamed quinoa ''chisiya mama'', which in Quechua means "mother of all grains".{{sfn|Cumo|2013|p=859}}

== Distribution ==
''Chenopodium quinoa'' is believed to have been domesticated in the Peruvian Andes from wild or weed populations of the same species.<ref>{{cite journal |author=Pickersgill, Barbara |author-link=Barbara Pickersgill |date=31 August 2007 |title=Domestication of plants in the Americas: Insights from Mendelian and molecular genetics |url=http://aob.oxfordjournals.org/cgi/content/full/mcm193v1 |url-status=dead |journal=Annals of Botany |volume=100 |issue=5 |pages=925–940 |doi=10.1093/aob/mcm193 |pmc=2759216 |pmid=17766847 |archive-url=https://web.archive.org/web/20071021154818/http://aob.oxfordjournals.org/cgi/content/full/mcm193v1 |archive-date=21 October 2007}}</ref> There are non-cultivated quinoa plants (''Chenopodium quinoa'' var.

==Cultivation==
Over the last 5,000{{nbsp}}years the biogeography of ''Ch. quinoa'' has changed greatly, mainly by human influence, convenience and preference. It has changed not only in the area of distribution, but also in regards to the climate this plant was originally adapted to, in contrast to the climates on which it is able to successfully grow in now. In a process started by a number of pre-Inca South American indigenous cultures, people in Chile have been adapting quinoa to salinity and other forms of stress over the last 3,000{{nbsp}}years.<ref name="Bazile2014" /> Quinoa is also cultivated, since an early date, near the coast of [[Norte Grande|northern Chile]], where it was grown by the [[Chinchorro culture]].{{sfn|Pardo|Pizarro|2015|p=148}} ''Ch.&nbsp;quinoa'' was brought to the lowlands of south-central Chile at an early date from the Andean highlands.{{sfn|Pardo|Pizarro|2015|p=147}}{{sfn|Pardo|Pizarro|2015|p=148}} Varieties in the lowlands of south-central Chile derive directly from ancestral cultivars which then evolved in parallel to those of the highlands.{{sfn|Pardo|Pizarro|2015|p=147}} It has been suggested that the introduction of ''Ch.&nbsp;quinoa'' occurred before highland varieties with [[flour]]y [[perisperm]] emerged.{{sfn|Pardo|Pizarro|2015|p=147}}{{sfn|Pardo|Pizarro|2015|p=148}} There are wide discrepancies in the suggested dates of introduction, one study suggests c. 1000 BC as the introduction date while another suggests 600–1100 AD.{{sfn|Pardo|Pizarro|2015|p=148}} In colonial times the plant is known to have been cultivated as far south as the [[Chiloé Archipelago]] and the shores of [[Nahuel Huapi Lake]].{{sfn|Pardo|Pizarro|2015|p=147}} The [[cuisine of Chiloé]] included bread made of quinoa until at least the mid-19th century.{{sfn|Pardo|Pizarro|2015|p=150}}

In Chile it had almost disappeared by the early 1940s; as of 2015 the crop is mostly grown in three areas by only some 300 smallholder farmers. Each of these areas is different: indigenous small-scale growers near the border with Bolivia who grow many types of Bolivian forms, a few farmers in the central region who exclusively grow a white-seeded variety and generally market their crops through a well-known cooperative, and in the south by women in home gardens in [[Mapuche]] reserves.<ref name="Bazile2014" />

When Amaranthaceae became abundant in [[Lake Pacucha]], Peru, the lake was fresh, and the lack of Amaranthaceae taxa strongly indicates droughts which turned the lake into a [[Salt marsh|saltmarsh]]. Based on the pollen associated with soil manipulation, this is an area of the Andes where domestication of ''C.{{nbsp}}quinoa'' became popular, although it was not the only one. It was domesticated in various geographical zones. With this, morphological adaptations began to happen until having five [[ecotype]]s today. Quinoa's genetic diversity illustrates that it was and is a vital crop.{{sfn|Murphy|Matanguihan|2015|p=14}}[[File:Calca Peru- Quinoa seller at mercado II.jpg|thumb|Quinoa seller at market in [[Calca, Peru]]]]Andean agronomists and nutrition scientists began researching quinoa in the early twentieth century, and it became the subject of much interest among researchers involved in [[neglected and underutilized crop]] studies in the 1970s.<ref name="McDonell">{{cite book |last1=Wilk |first1=Richard |url=https://www.bloomsbury.com/uk/critical-approaches-to-superfoods-9781350123878/ |title=Critical Approaches to Superfoods |last2=McDonell |first2=Emma |publisher=Bloomsbury Publishing Plc |year=2020 |isbn=978-1-350-12387-8 |publication-place=London |page= |oclc=1204141540}}</ref>

In 2004, the international community became increasingly interested in quinoa and it entered a boom and bust economic cycle that would last for over ten years. Between 2004 and 2011, quinoa became a more interesting commodity and global excitement for it increased. At this point, Bolivia and Peru were the only major producers of quinoa. In 2013, there was an extreme increase in imports of quinoa by the United States, Canada and various European countries. In 2016, growth began to slow. Imports were still increasing but at a slower rate and quinoa prices declined as other countries began producing it.<ref name=":2" /> By 2015, over 75 countries were producing quinoa, as opposed to only eight countries in the 1980s.<ref>{{Cite journal |last1=Bazile |first1=Didier |last2=Jacobsen |first2=Sven-Erik |last3=Verniau |first3=Alexis |date=2016-05-09 |title=The Global Expansion of Quinoa: Trends and Limits |journal=Frontiers in Plant Science |language=English |volume=7 |page=622 |doi=10.3389/fpls.2016.00622 |issn=1664-462X |pmc=4860459 |pmid=27242826 |doi-access=free|bibcode=2016FrPS....7..622B }}</ref>

Particularly for the high variety of Chilean landraces, in addition to how the plant has adapted to different latitudes, this crop is now potentially cultivable almost anywhere in the world.<ref name="Bazile2014" />

===Climate requirements===
The plant's growth is highly variable due to the number of different subspecies, varieties and [[landrace]]s (domesticated plants or animals adapted to the environment in which they originated). However, it is generally undemanding and altitude-hardy; it is grown from coastal regions to over {{cvt|4000|m|ft}} in the Andes near the equator, with most of the cultivars being grown between {{cvt|2500|m|ft}} and {{cvt|4000|m|ft}}. Depending on the variety, optimal growing conditions are in cool climates with temperatures that vary between {{cvt|-4|C|F}} during the night to near {{cvt|35|C|F}} during the day. Some cultivars can withstand lower temperatures without damage. Light frosts normally do not affect the plants at any stage of development, except during flowering. Midsummer frosts during flowering, a frequent occurrence in the Andes, lead to sterilization of the pollen. Rainfall requirements are highly variable between the different cultivars, ranging from {{cvt|300|to|1000|mm|in}} during the [[growing season]]. Growth is optimal with well-distributed rainfall during early growth and no rain during seed maturation and harvesting.<ref name="Lost crops" />

=== Sowing ===
Quinoa requires a significant amount of precipitation in order to germinate, therefore the traditional sowing date in [[Peru]] was between September and November. To increase the chance that more crops survive it would be advantageous to split up the sowing date among the plants. Traditionally quinoa was sowed by broadcast, in rows or grooves, or by broadcast and then making rows.

===Harvesting===
Traditionally, quinoa grain is harvested by hand, and only rarely by machine, because the extreme variability of the maturity period of most quinoa cultivars complicates mechanization. Harvest needs to be precisely timed to avoid high seed losses from shattering, and different panicles on the same plant mature at different times.<ref>{{Cite web |url=https://homeguides.sfgate.com/harvest-quinoa-90172.html |title=How to Harvest Quinoa |website=homeguides.sfgate.com |date=29 October 2013 |access-date=2020-02-21}}</ref><ref>{{Cite web |url=https://www.huffpost.com/entry/how-does-quinoa-grow_n_592e1cf0e4b0e95ac194de75 |title=Bet You Had No Idea What Quinoa Looks Like When It Grows |date=2017-06-01 |website=HuffPost |access-date=2020-02-21}}</ref> The [[crop yield]] in the Andean region (often around 3 t/ha up to 5 t/ha) is comparable to wheat yields.

=== Processing ===
The plants are allowed to stand until the stalks and seeds have dried out and the grain has reached a moisture content below 10%.
Handling involves [[threshing]] the seedheads from the [[chaff]] and [[winnowing]] the seed to remove the [[husk]]. Before storage, the seeds need to be dried in order to avoid [[germination]].<ref name="Lost crops" /> This was traditionally done manually, which is labour-intensive.<ref name="Bazile2014">{{cite journal |last1=Bazile |first1=Didier |last2=Martínez |first2=Enrique A. |last3=Fuentes |first3=Francisco |date=2014-12-02 |title=Diversity of quinoa in a biogeographical island: A review of constraints and potential from arid to temperate regions of Chile |url=https://www.notulaebotanicae.ro/index.php/nbha/article/view/9733 |journal=Notulae Botanicae Horti Agrobotanici Cluj-Napoca |volume=42 |issue=2 |pages=289–298|doi=10.15835/nbha.42.2.9733 |bibcode=2014NBHAC..42.9733B }}</ref>

In terms of wider social consequences, research on traditional producers in Bolivia has emphasised a complex picture.

Raw, uncooked quinoa is 13% water, 64% [[carbohydrates]], 14% [[protein]], and 6% [[fat]]. Nutritional evaluations indicate that a {{cvt|100|g|oz|abbr=off|frac=2|adj=on}} serving of raw quinoa seeds has a [[food energy]] of {{cvt|1,539|kJ|kcal|abbr=off}} and is a rich source (20% or higher of the [[Daily Value]], DV) of protein, [[dietary fiber]], several [[B vitamins]], including 46%{{nbsp}}DV for [[folate]], and for several [[dietary minerals]] such as [[Magnesium in biological systems|magnesium]] (55%{{nbsp}}DV), [[manganese]] (95%{{nbsp}}DV), [[phosphorus]] (65%{{nbsp}}DV), and [[zinc]] (33%{{nbsp}}DV).

After boiling, which is the typical preparation for eating the seeds, many nutritional evaluations change. Although a {{cvt|100|g|oz|frac=2}} serving of cooked quinoa increases to 72% water, most nutritional evaluations are reduced, such as, 21% carbohydrates, 4% protein, and 2% fat,<ref name="johnson" /> and the food energy of cooked quinoa is reduced to {{cvt|503|kJ|kcal|abbr=off}}. Although similarly reduced, cooked quinoa remains a rich source of the dietary minerals manganese (30%{{nbsp}}DV) and phosphorus (22%{{nbsp}}DV). However, cooked quinoa is reduced to being just a moderate source (10–19%{{nbsp}}DV) of dietary fiber and folate (11%), as well as of the dietary minerals iron (11%), magnesium (18%), and zinc (11%).

Quinoa is [[gluten-free]].<ref name="FAOquinoaancientcrop" /> Because quinoa has a high concentration of [[protein (nutrient)|protein]] and is a good source of many [[micronutrient]]s, has versatility in preparation, and a potential for increased yields in controlled environments,<ref name="AbugochJames2009">{{cite journal |last=Abugoch |first=James L.
