Argania

Argania (Tashelhit: ⴰⵔⴳⴰⵏ Argan) is a genus of flowering plants containing the sole species Argania spinosa, known as argan, a tree endemic to the calcareous semidesert Sous valley of southwestern Morocco and to the region of Tindouf in southwestern Algeria Argan trees grow to 8–10 m (26–33 ft) high and live up to approximately 200 years. They are thorny, with gnarled trunks and wide spreading crown. The crown has a circumference of about 70 m (230 ft) and the branches lean towards the ground.

The leaves are small, 2–4 cm (0.79–1.57 in) long, and oval with a rounded apex. The flowers are small, with five pale yellow green petals; flowering in April. The fruit is 2–4 cm (0.79–1.57 in) long and 1.5–3 cm (0.59–1.18 in) broad, with a thick, bitter peel surrounding a sweet-smelling but unpleasantly flavored layer of pulpy pericarp. This surrounds the very hard nut, which contains one (occasionally two or three) small, oil-rich seeds. The fruit takes over a year to mature, ripening in June to July of the following year.

Name

The scientific name Argania is derived from argan, the name of the tree in Shilha, the Berber language which is spoken by the majority of the people living in the areas where the tree is endemic. Shilha Berber has a rich vocabulary for the various parts of the fruit, its stages of ripeness, and its harvesting and processing. The oil is also called argan. In medieval Arabic pharmacological sources, the tree is known as harjān, a distortion of the Berber word argan.

United Nations International Day

On the 3 March 2021, the United Nations General Assembly adopted a resolution to proclaim the 10 May the International Day of Argania, an observance to be celebrated annually.[6] Amongst the motivations for this proclamation were the importance of Argania to sustainable development where it is endemic. The UN resolution was submitted by Morocco, and was co-sponsored by 113 member states of the United Nations before being adopted by consensus

Cultivation

In Morocco, arganeraie forests now cover some 8,280 km2 (3,200 sq mi) and are designated as a UNESCO biosphere reserve. Their area has shrunk by about half during the last 100 years, due to charcoal making, grazing, and increasingly intensive cultivation. The best hope for the conservation of the trees may lie in the recent development of a thriving export market for argan oil as a high-value product. However, the wealth brought by argan oil export has also created threats to argan trees in the form of increased goat population. Locals use the newfound wealth to buy more goats and the goats stunt the growth of the argan trees by climbing up and eating their leaves and fruit.[8] It is reported that the display of the tree climbing goats is staged or faked.

The production of the oil is done by hand

Argan is also grown in the Arabah and Negev regions of Israel.

Uses

In some parts of Morocco, argan takes the place of the olive as a source of forage, oil, timber, and fuel in Berber society.

Especially near Essaouira, the argan tree is frequently climbed by goats.

 Fruit

Argan fruit falls in July, when they are black and dry. Until this happens, goats are kept out of the argan woodlands by wardens. Rights to collect the fruit are controlled by law and village traditions. The "nuts" are gathered after fruit consumption and spat out by ruminating goats. Seeds being spat out by the goats constitutes one mechanism of seed dispersal.

Argan oil

Argan oil is produced by several women's co-operatives in the southwestern parts of Morocco. The most labor-intensive part of oil-extraction is removal of the soft pulp (used to feed animals) and the cracking by hand, between two stones of the hard nut. The seeds are then removed and gently roasted. This roasting accounts for part of the oil's distinctive, nutty flavor.

The traditional technique for oil extraction is to grind the roasted seeds to paste, with a little water, in a stone rotary quern. The paste is then squeezed by hand to extract the oil. The extracted paste is still oil-rich and is used as animal feed. Oil produced this way can be stored and used for 3–6 months, and can be produced as needed from kernels, which can keep for 20 years unopened. Dry-pressing is becoming increasingly important for oil produced for sale, as this method allows for faster extraction, and the oil produced can be used for 12–18 months after extraction.

The oil contains 80% unsaturated fatty acids, is rich in essential fatty acids, and is more resistant to oxidation than olive oil. Argan oil is used for dipping bread, on couscous, salads, and similar uses. A dip for bread known as amlou is made from argan oil, almonds, and peanuts, sometimes sweetened by honey or sugar. The unroasted oil is traditionally used as a treatment for skin diseases and has become favoured by European cosmetics manufacturers.

Argan oil is sold in Morocco as a luxury item. Sales of the product have grown since being marketed by the cosmetics industry in the US and Europe in the early 21st century. Its price is notable compared to other oils.

Argan oil contains:

46% Oleic acid

32% Linoleic acid

12% Palmitic acid

6% Stearic acid

Animal feed

Argan trees are a major source of forage for sheep, goats, camels, and cattle. Fruits and leaves are readily consumed by livestock. The press cake resulting from oil extraction can also be sun dried and fed to ruminants. Bees can nest in argan trees, making them sites for wild honey harvesting.
