Favorite pictures on the wall
Tear them down and rip them all
Spread the pieces in a line
String the needle through with thread
Sew them all back up and then
Claim the pictures, now they're mine
I am a poet, I am a thief
Create by imitating what I see
Fooled again, by the muse inside my pen
To think that what was born had come from me
Hated pictures on the wall
Tear them down and rip them all
Feed the pieces to a flame
Grind the ashes to the ground
Snuff them out so they're not found
They never really held my name
I am lost, I am ashamed
The thoughts my body stole have reached my brain
Kill the plan, now I'm back where I began
But I still have the blood of others in my veins
In my veins!
I am a poet, I am a thief!
Create by imitating what I see
Fooled again, by the muse inside my pen
To think that what was born had come from me

Every waking moment
Tethered to our sweet machines
Wire life-support
Umbilical that saps and feeds
Comfort from the static sounds
Hours drained into the screen
Burned into my tired mind
Ones and zeroes fill my dreams
Separated from the world
Voluntary isolation
Luminescence is a god
It kills all sense of trepidation
Kills all sense of anything
Lobotomies and mutilation
Blinded to the march of time
We settle into our sedation
Drained! Of creativity
Slaves! To our inactivity
Safe! In captivity
Mired in our dereliciton
Doomed to service our addiction
We worship at the alter
Of our electric kings
Be sure to never falter
Don't miss the next big thing
Stave off your obsolescense
Pursue that modern dream
Fade out, submit your senses
To our sweet machines
Living deep within our heads
Trapped in dream and fantasy
A program-perfect picture of
The way the the world can never be
Look outside and were surprised
What did we expect to see?
Go running to our motherboards
To hide from harsh reality
Made! To see what we can spend
Played! Into a hopeless trend
Trained! The cycle never ends
Were afflicted with an illness
Agents to the death of stillness
We worship at the alter
Of our electric kings
Be sure to never falter
You'll miss the next big thing
Stave off your obsolescense
Pursue that modern dream
Fade out, submit your senses
To our sweet machines
Pander on the showroom floor
Push the product out the door
A meaningless reiteration
Passed off as a fresh creation
Tired lies for naive eyes
A coat of paint, a bottom line
A lonely day, a lack of sleep
Aquire, retire, rinse repeat!
We worship at the alter
Of our electric kings
Be sure to never falter
Don't miss the next big thing
Stave off your obsolescense
Pursue that modern dream
Fade out, submit your senses
To our sweet machines

Point of No Return

Is it as easy as that?
A momentary contact
Of eyes 'cross the room
Incendiary contract
Signed in the gloom
Shaking from the impact
You're not coming back
No you're not coming back from this
Is it as simple as this?
A fleeting little kiss
Stolen at first
Then returned with interest
Weak to the thirst
Becoming an accomplice
You're not coming back
No you're not coming back from this...
Time you've crossed the point of no return
You can't turn back the bridge is
Burning in your face, into your skin
An ugly scar displays your sins
She can't take anymore
She's heading for the door
Try to pursue
But you're glued to the floor
Payed what you're due
I think you knew the score
But it hurts when it hits
No you're not coming back from this...
Time you've crossed the point of no return
You can't turn back the bridge is
Burning in your face, into your skin
An ugly scar displays
Your sins
Once, so long ago, she called me king
Now I'm not anything
And so the life that I saw for myself
Gathers dust on the shelf
Late at night, wrapped up in feeling
Pictures dance on ceiling
I try to chase them with a broken wing
Once, she called me king

Please
Oh help me please
I need re-

From this disease
That eats my
Brain
And burns my veins
I turn a-
way
But she remains
Mocking me
Close
So very close
But can't be held
Cold
Just like a ghost
But I'm compelled
Less
Just like the
Rest
Who can't attain
Yes
I am obsessed
But can't explain
Why
She's stuck on my mind
She's stuck on my mind
Taste
A little taste
Is all it
Takes
To cut the brakes
And watch me
Slip
Into her grip
A hold so
Tight
It makes me sick
And I'm right
Back
Where I began
And though I
Lack
What she demands
I just can't
Seem
To let this be
If I just
Leave
I could be free
Believe me, I
Know
I should let her go
I can't let her go
I can't let her go!
You know she's unattainable (x12)
Why
Can't I let this die?
She's stained on my eyes
She's stuck on my mind

Wait
Won't you give me a minute
Wait
I'm afraid of the distance
Multiplied to miles wide
She's only inches from my side
I freeze
You can shatter me with ease
Watch me crumble the floor and beg for more
I am a glutton for the punishment in store
From you
You pretty little thing
You got me glued, subdued
I'm coiled like a spring
Just cut me loose, diffuse
The tension in my chest
End the abuse, and choose
To stay or let me rest
I need to know
I
Am as naive as they come
Vulnerable and dumb
You can change me with a word
I'll crash and burn or rise above
You've got me wrapped in chains
But I'll fight through the pain
That's breaking through my skull
'Cuz I am powerless to fight the pull
From you
You pretty little thing
You got me glued, subdued
I'm coiled like a spring
Just cut me loose, diffuse
The tension in my chest
End the abuse, and choose
To stay or let me rest
I need to know
You reside
Behind a wall
Inside my mind
A mile tall
Compelled to climb
But scared to fall
Compelled to climb
But scared to fall away
From you
You pretty little thing
You got me glued, subdued
I'm coiled like a spring
Just cut me loose, diffuse
The tension in my chest
End the abuse, and choose
To stay or let me rest
I need to know

I think it is magnetic
Interacting with the static in the streets
I'll take all of the dust into my skin and lungs
And leave it there for weeks
It makes a current of the concrete
I'll ride it like a wave
I'll absorb it's energy
And take it to my grave
Everybody's with me in a cavalcade cacophony display
Show the electricity
That's crackling beneath your feet a home
Dig your toes in deep and revel in the heat
It knows just where to go
It's going through your skeleton
It animates your limbs
It gathers in your stomach
And explodes you from within
It's bursting from your fingertips and when it hits it changes who you've been
Can't you feel it in the water?
Can't you smell it in the sky?
It's a chemical reaction
Born from passion and drive
It gathers us together
Changing weather as it flies
It's started countless fires
Can't you see it in our eyes?
Can't you feel it in the water?

Yams
02:33
|
|||
Yam is the common name for some plant species in the genus Dioscorea (family Dioscoreaceae) that form edible tubers.[1] Yams are perennial herbaceous vines cultivated for the consumption of their starchy tubers in many temperate and tropical world regions.[1] The tubers themselves are also called "yams", having numerous cultivars and related species.[1]
In parts of the United States and Canada, "yam" is sometimes used to refer to varieties of the unrelated sweet potato (Ipomoea batatas).
Etymology
The name, yam, appears to derive from Portuguese inhame or Canarian (Spain) ñame, which are probably derived from West African languages.[2] The main derivations borrow from verbs meaning "to eat".[2]
Other uses of the term yam
Several other unrelated root vegetables are sometimes referred to as "yams",[1] including:
Sweet potato (Ipomoea batatas), especially those with orange flesh, are often referred to as "yams" in the United States.[3] Today, the U.S. Department of Agriculture requires[4] sweet potatoes labeled with the term "yam" to be accompanied by the term "sweet potato".
Purple sweet potatoes in Okinawa.
Oca (Oxalis tuberosa) in New Zealand is typically referred to as "yam".[5][6]
Konjac corms - a Japanese vegetable with similar uses - is often colloquially referred to as a "yam",[7] although it is unrelated.
Taro in Malaysia and Singapore is referred to as "yam".[8]
Yam has various common names across multiple world regions.[1]
Description
A monocot related to lilies and grasses, yams are vigorous herbaceous vines, providing an edible tuber.[1] They are native to Africa, Asia, and the Americas. Some yams are also invasive plants, often considered a "noxious weed", outside cultivated areas.[1] Yam tubers vary in size from that of a small potato to over 60 kg (130 lb). Some 870 species of yams are known,[1] and 95% of these crops are grown in Africa.[9]
Yam tubers can grow up to 15 m (49 ft) in length and 7.6 to 15.2 cm (3.0 to 6.0 in) high.[1] The tuber may grow into the soil up to 1.5 metres (4.9 ft) deep.[1] The plant disperses by seed.[1]
The edible tuber has a rough skin difficult to peel, but softens after heating. The skins vary in color from dark brown to light pink. The majority of the vegetable is composed of a much softer substance known as the "meat". This substance ranges in color from white or yellow to purple or pink in mature yams.
Cultivation
Yam crop begins when whole seed tubers or tuber portions are planted into mounds or ridges, at the beginning of the rainy season. The crop yield depends on how and where the setts are planted, sizes of mounds, interplant spacing, provision of stakes for the resultant plants, yam species, and tuber sizes desired at harvest. Small-scale farmers in West and Central Africa often intercrop yams with cereals and vegetables. The seed yams are perishable and bulky to transport. Farmers who do not buy new seed yams usually set aside up to 30% of their harvest for planting the next year. Yam crops face pressure from a range of insect pests and fungal and viral diseases, as well as nematode. Their growth and dormant phases correspond respectively to the wet season and the dry season. For maximum yield, the yams require a humid tropical environment, with an annual rainfall over 1500 mm distributed uniformly throughout the growing season. White, yellow, and water yams typically produce a single large tuber per year, generally weighing 5 to 10 kg (11 to 22 lb).[10]
Despite the high labor requirements and production costs, consumer demand for yam is high in certain subregions of Africa,[1] making yam cultivation quite profitable to certain farmers.
Major cultivars

Many cultivars of yams are found throughout the humid tropics.[1] The most economically important are discussed below.[10]
D. rotundata and D. cayenensis
Dioscorea rotundata, the white yam, and D. cayenensis, the yellow yam, are native to Africa. They are the most important cultivated yams. In the past, they were considered as two separate species, but most taxonomists now regard them as the same species. Over 200 varieties between them are cultivated.
White yam tuber is roughly cylindrical in shape, the skin is smooth and brown, and the flesh is usually white and firm. Yellow yam has yellow flesh, caused by the presence of carotenoids. It looks similar to the white yam in outer appearance; its tuber skin is usually a bit firmer and less extensively grooved. The yellow yam has a longer period of vegetation and a shorter dormancy than white yam.
The 'Kokoro' variety is important in making dried yam chips.[11]
They are large plants; the vines can be as long as 10 to 12 m (33 to 39 ft). The tubers most often weigh about 2.5 to 5 kg (5.5 to 11.0 lb) each, but can weigh as much as 25 kg (55 lb). After 7 to 12 months' growth, the tubers are harvested. In Africa, most are pounded into a paste to make the traditional dish of "pounded yam," known as Fufu.[12]
D. alata
Water yam (D. alata)
D. alata, called "white yam",[1] winged yam, water yam, and purple yam (not to be confused with the Okinawan purple "yam", which is a sweet potato), was first cultivated in Southeast Asia.[1] Although not grown in the same quantities as the African yams, it has the largest distribution worldwide of any cultivated yam, being grown in Asia, the Pacific islands, Africa, and the West Indies.[1][13] Even in Africa, the popularity of water yam is second only to white yam. The tuber shape is generally cylindrical, but can vary. Tuber flesh is white and watery in texture.
Uhi was brought to Hawaii by the early Polynesian settlers and became a major crop in the 19th century when the tubers were sold to visiting ships as an easily stored food supply for their voyages.[14]
D. polystachya
Segment of a Chinese yam
D. polystachya, Chinese yam, is native to China. The Chinese yam plant is somewhat smaller than the African, with the vines about 3 m (9.8 ft) long. It is tolerant to frost and can be grown in much cooler conditions than other yams. It is also grown in Korea and Japan.
It was introduced to Europe in the 19th century, when the potato crop there was falling victim to disease, and is still grown in France for the Asian food market.
The tubers are harvested after about 6 months of growth. Some are eaten right after harvesting and some are used as ingredients for other dishes, including noodles, and for traditional medicines.[12]
D. bulbifera
Air potato
Wild yams
D. bulbifera, the air potato, is found in both Africa and Asia, with slight differences between those found in each place. It is a large vine, 6 m (20 ft) or more in length. It produces tubers, but the bulbils which grow at the base of its leaves are the more important food product. They are about the size of potatoes (hence the name "air potato"), weighing from 0.5 to 2.0 kg (1.1 to 4.4 lb).
Some varieties can be eaten raw, while some require soaking or boiling for detoxification before eating. It is not grown much commercially since the flavor of other yams is preferred by most people. However, it is popular in home vegetable gardens because it produces a crop after only four months of growth and continues producing for the life of the vine, as long as two years. Also, the bulbils are easy to harvest and cook.[12]
In 1905, the air potato was introduced to Florida and has since become an invasive species in much of the state. Its rapid growth crowds out native vegetation and is very difficult to remove since it can grow back from the tubers, and new vines can grow from the bulbils even after being cut down or burned.[15]
D. esculenta
Wild bitter yam vines
D. esculenta, the lesser yam, was one of the first yam species cultivated. It is native to Southeast Asia and is the third-most commonly cultivated species there, although it is cultivated very little in other parts of the world. Its vines seldom reach more than 3 m (9.8 ft) in length and the tubers are fairly small in most varieties.
The tubers are eaten baked, boiled, or fried much like potatoes. Because of the small size of the tubers, mechanical cultivation is possible, which along with its easy preparation and good flavor, could help the lesser yam to become more popular in the future.[12]
D. dumetorum
D. dumetorum, the bitter yam, is popular as a vegetable in parts of West Africa, in part because their cultivation requires less labor than other yams. The wild forms are very toxic and are sometimes used to poison animals when mixed with bait. It is said that they have also been used for criminal purposes.[12]
D. trifida
D. trifida, the cush-cush yam, is native to the Guyana region of South America and is the most important cultivated New World yam. Since they originated in tropical rainforest conditions, their growth cycle is less related to seasonal changes than other yams. Because of their relative ease of cultivation and their good flavor, they are considered to have a great potential for increased production.[12]
Harvesting
Yams in west Africa are typically harvested by hand using sticks, spades, or diggers.[16] Wood-based tools are preferred to metallic tools as they are less likely to damage the fragile tubers; however, wood tools need frequent replacement. Yam harvesting is labor-intensive and physically demanding. Tuber harvesting involves standing, bending, squatting, and sometimes sitting on the ground depending on the size of mound, size of tuber, or depth of tuber penetration. Care must be taken to avoid damage to the tuber, because damaged tubers do not store well and spoil rapidly. Some farmers use staking and mixed cropping, a practice that complicates harvesting in some cases.
In forested areas, tubers grow in areas where other tree roots are present. Harvesting the tuber then involves the additional step of freeing them from other roots. This often causes tuber damage.
Aerial tubers or bulbils are harvested by manual plucking from the vine.
Yields may improve and cost of yam production be lower if mechanization were to be developed and adopted. However, current crop production practices and species used pose considerable hurdles to successful mechanization of yam production, particularly for small-scale rural farmers. Extensive changes in traditional cultivation practices, such as mixed cropping, may be required. Modification of current tuber harvesting equipment is necessary given yam tuber architecture and its different physical properties.[16]

Worldwide yam production
In 2014, worldwide production of yams was 68.1 million tonnes, led by Nigeria with 66% of the global total (table). Nigeria farmed yams on 5.4 million hectares, 70% of the world land area of 7.8 million hectares devoted to yam farming.[17]
The world average annual yield of yams was 8.8 tonnes per hectare in 2014, with Ethiopia having the most productive farms of 29.7 tonnes per hectare.[17]
Storage
Roots and tubers such as yam are living organisms. When stored, they continue to respire, which results in the oxidation of the starch (a polymer of glucose) contained in the cells of the tuber, which converts it into water, carbon dioxide, and heat energy. During this transformation of the starch, the dry matter of the tuber is reduced.
Amongst the major roots and tubers, properly stored yam is considered to be the least perishable. Successful storage of yams requires:[18][19]
initial selection of sound and healthy yams
proper curing, if possible combined with fungicide treatment
adequate ventilation to remove the heat generated by respiration of the tubers
regular inspection during storage and removal of rotting tubers and any sprouts that develop
protection from direct sunlight and rain
Storing yam at low temperature reduces the respiration rates. However, temperatures below 12 °C (54 °F) cause damage through chilling, causing a breakdown of internal tissues, increasing water loss and yam's susceptibility to decay. The symptoms of chilling injury are not always obvious when the tubers are still in cold storage. The injury becomes noticeable as soon as the tubers are restored to ambient temperatures.
The best temperature to store yams is between 14 and 16 °C (57 and 61 °F), with high-technology-controlled humidity and climatic conditions, after a process of curing. Most countries that grow yam as food staple are too poor to afford high-technology storage systems.
Sprouting rapidly increases a tuber's respiration rates, and accelerates the rate at which its food value decreases.[18]
Certain cultivars of yams store better than others. The easier to store yams are those adapted to arid climate, where they tend to stay in a dormant low-respiration stage much longer than yam breeds adapted to humid tropical lands, where they do not need dormancy. Yellow yam and cush-cush yam, by nature, have much shorter dormancy periods than water yam, white yam, or lesser yam.
Storage losses for yams are very high in Africa, with insects alone causing over 25% harvest loss within 4 months.

Raw yam has only moderate nutrient density, with appreciable content (10% or more of the Daily Value, DV) limited to potassium, vitamin B6, manganese, thiamin, dietary fiber, and vitamin C (table).[20] Yam supplies 118 Calories per 100 grams. Yam generally has a lower glycemic index, about 54% of glucose per 150-gram serving, compared to potato products.[21]
The protein content and quality of roots and tubers is lower than other food staples, with the content of yam and potato being around 2% on a fresh-weight basis. Yams, with cassava, provide a much greater proportion of the protein intake in Africa, ranging from 6% in East and South Africa to about 16% in humid West Africa.[citation needed]
As a relatively low-protein food, yam is not a good source of essential amino acids. Experts emphasize the need to supplement a yam-dominant diet with more protein-rich foods to support healthy growth in children.[22][23]
Yam is an important dietary element for Nigerian and West African people. It contributes more than 200 calories per person per day for more than 150 million people in West Africa, and is an important source of income. Yam is an attractive crop in poor farms with limited resources. It is rich in starch, and can be prepared in many ways. It is available all year round, unlike other, unreliable, seasonal crops. These characteristics make yam a preferred food and a culturally important food security crop in some sub-Saharan African countries.[24]
Phytochemicals
The tubers of certain wild yam, a variant of kokoro yam and other species of Dioscorea, such as Dioscorea nipponica, are a source for the extraction of diosgenin, a steroid sapogenin.[25] The extracted diosgenin is used for the commercial synthesis of cortisone, pregnenolone, progesterone, and other steroid products.[26] Such preparations were used in early combined oral contraceptive pills.[27] The unmodified steroid has estrogenic activity.[28]
Comparison to other staple foods
The following table shows the nutrient content of yam and major staple foods in a raw harvested form. Raw forms, however, are not edible and cannot be digested. These must be sprouted, or prepared and cooked for human consumption. In sprouted or cooked form, the relative nutritional and antinutritional contents of each of these staples is remarkably different from that of raw form of these staples.[citation needed]

Yams are consumed in a variety of preparations, such as flour or whole vegetable pieces across their range of distribution in Asia, Africa, North America, Central America, the Caribbean, South America, and Oceania.[1]
Africa

Yams of African species must be cooked to be safely eaten, because various natural substances in yams can cause illness if consumed raw. The most common cooking methods in Western and Central Africa are by boiling, frying or roasting.[30]
Among the Akan of Ghana, boiled yam can be mashed with palm oil into eto in a similar manner to the plantain dish matoke, and is served with eggs. The boiled yam can also be pounded with a traditional mortar and pestle to create a thick, starchy paste known as iyan (pounded yam) or fufu which is eaten with traditional sauces such as egusi and palm nut soup.
Another method of consumption is to leave the raw yam pieces to dry in the sun. When dry, the pieces turn a dark brown color. These are then milled to create a brown powder known in Nigeria as elubo. The powder can be mixed with boiling water to create a thick starchy paste, a kind of pudding known as amala, which is then eaten with local soups and sauces.
Yams are a primary agricultural and culturally important commodity in West Africa,[30] where over 95% of the world's yam crop is harvested. Yams are still important for survival in these regions. Some varieties of these tubers can be stored up to six months without refrigeration, which makes them a valuable resource for the yearly period of food scarcity at the beginning of the wet season. Yam cultivars are also cultivated in other humid tropical countries.[1]
Yam is the main staple crop of the Igbos in south eastern Nigeria where for centuries it played a dominant role in both their agricultural and cultural life. It is celebrated with annual yam festivals
Philippines and Costa Rica

In the Philippines, the purple ube species of yam (Dioscorea alata), is eaten as a sweetened dessert called ube halaya, and is also used as an ingredient in another Filipino dessert, halo-halo. It is also used as a popular ingredient for ice cream.
Vietnam
In Vietnam, the same purple yam is used for preparing a special type of soup canh khoai mỡ or fatty yam soup. This involves mashing the yam and cooking it until very well done.
Indonesia
In Indonesia, the same purple yam is used for preparing desserts. This involves mashing the yam and mixing it with coconut milk and sugar. White- and off-white-fleshed yams are cut in cubes, cooked, lightly fermented, and eaten as afternoon snacks.
Japan
Yamakake is a yam-based Japanese dish prepared from tororo and maguro.
An exception to the cooking rule is the mountain yam (Dioscorea polystachya), known as nagaimo and can be further classified into ichōimo (lit. 'ginkgo-leaf yam'; kanji: 銀杏芋), or yamatoimo (lit. Yamato yam; kanji: 大和芋), depending on the root shape.
Nagaimo is eaten raw and grated, after only a relatively minimal preparation: the whole tubers are briefly soaked in a vinegar-water solution to neutralize irritant oxalate crystals found in their skin. The raw vegetable is starchy and bland, mucilaginous when grated, and may be eaten plain as a side dish, or added to noodles.
Another variety of yam, jinenjo, is used in Japan as an ingredient in soba noodles. In Okinawa, purple yams (Dioscorea alata) are grown. This is known locally as daijo or beniimo. This purple yam is popular as lightly deep-fried tempura, as well as being grilled or boiled. Additionally, the purple yam is a common ingredient of yam ice cream with the signature purple color. Purple yam is also used in other types of traditional wagashi sweets, cakes, and candy.
India
In central parts of India, the yam (khamalu, suran, or chupri alu) is prepared by being finely sliced, seasoned with spices, and deep fried. In southern parts of India, known as karunai kizhangu in Tamil, the vegetable is a popular accompaniment to rice dishes and fish curry. Also eaten in India, D. alata, a purple-pigmented species, is known as ratalu or violet yam.
In the southern part, especially in Kerala, both purple and white colored yams are locally known as kaachil or kavuttu.
In Karnataka, it is known as suvarna gadde in Kannada language. In central India, it is also called garadu". In Andhra Pradesh, it is known as ganisi gadda.
Nepal
Dioscorea root is traditionally eaten on Māgh Sankrānti (a midwinter festival) in Nepal. In Nepali, it is called tarul and in Newari hī. It is usually steamed and then cooked with spices.
Fiji Islands
Yam, known locally in Fiji as "uvi",[31] may replace cassava or taro as a staple, and is consumed boiled, roasted in a lovo, or steamed with fish or meat in curry sauce or coconut milk and served with rice. The cost of yam is higher due to the difficulty in farming and relatively low volume of production on Fiji.[31]
The West
Yam powder is available in the West from grocers specializing in African products, and may be used in a similar manner to instant mashed potato powder, although preparation is a little more difficult because of the tendency to form lumps. The yam powder is sprinkled onto a pan containing a small amount of boiling water, and stirred vigorously. The resulting mixture is served with a heated sauce, such as tomato and chili, poured onto it.
Because of their abundance and importance to survival, yams were highly regarded in Jamaican ceremonies and constitute part of many traditional West African ceremonies.[32]
Toxicity

Unlike cassava, most varieties of edible, mature, cultivated yam do not contain toxic compounds. However, there are exceptions. Bitter compounds tend to accumulate in immature tuber tissues of white and yellow yams. These may be polyphenols or tannin-like compounds.[citation needed]
Wild forms of bitter yams do contain some toxins that taste bitter, hence are referred to as bitter yam. Bitter yams are not normally eaten except at times of desperation in poor countries and in times of local food scarcity. They are usually detoxified by soaking in a vessel of salt water, in cold or hot fresh water or in a stream. The bitter compounds in these yams are water-soluble alkaloids which, on ingestion, produce severe and distressing symptoms. Severe cases of alkaloid intoxication may prove fatal.
Aerial or potato yams have antinutritional factors. In Asia, detoxification methods, involving water extraction, fermentation, and roasting of the grated tuber, are used for bitter cultivars of this yam. The bitter compounds in yams also known locally as air potato include diosbulbin and possibly saponins, such as diosgenin.[25] In Indonesia, an extract of air potato is used in the preparation of arrow poison.[18]
Ashanti yam ceremony in Ghana has been part of the local history, shown in this 1817 painting of a yam ceremony
Cultural aspects
Nigeria and Ghana
A yam festival is usually held in the beginning of August at the end of the rainy season. People offer yams to gods and ancestors first, before distributing them to the villagers. This is their way of giving thanks to the spirits above them.
New Yam Festival
The New Yam Festival celebrates the main agricultural crop of the Igbos, Idomas, and Tivs. The New Yam Festival, known as Orureshi in Owukpa in Idoma west and Ima-Ji, Iri-Ji or Iwa Ji in Igbo land, is a celebration depicting the prominence of yam in social and cultural life. The festival is prominent among southeastern states and major tribes in Benue State, mainly around August.
Other
Historical records in West Africa and of African yams in Europe date back to the 16th century. Yams were taken to the Americas through precolonial Portuguese and Spanish on the borders of Brazil and Guyana, followed by a dispersion through the Caribbean.[33]
Yams are used in Papua New Guinea, where they are called kaukau. Their cultivation and harvesting is accompanied by complex rituals and taboos. The coming of the yams (one of the numerous versions from Maré) is described in Pene Nengone (Loyalty Islands – New Caledonia).

Beneath the surface
I feel the creatures sitting, waiting, ready to break
Free from all the places
Deep inside where i had chased them
They'll wait for me to sleep and then they'll take me away
They'll sink their teeth in
Devoured by their avarice I'll never escape
I said this is the last day
I swear this is the last day
I just need once more taste
I said just one more little taste
I need my...

Vices
C'mon, give it to me
Beneath the surface
I know that I am drowning but I no longer care
I feel a completeness
When I'm swimming in this sweetness
Sinking to the bottom when I should fight for air
I am an animal, I've become their prey
This is not the last day
I know it's not the last day
But I don't want to change
Oh no, you'll never make me change
I need my...

Grab me by the gut now
And don't you dare let me go
I want to take a ride
But I don't want to be in control
I want to feel the room shake
Shake me down to my bones
And you're coming with me
You know I'm not going alone
Plunge me in deep, deep, deep
Until I cannot breathe
Drown me in bass frequency
Let it filter up now
Through your feet and out your eyes
Let it fill you up completely
Let it melt you down from the inside
Vibrations wash over you
Catch you up in the tide
Feel the waves take you there
Watch them all crash and collide
It's got us by the gut and
Now it's brought us to our knees
Drown me in bass frequency
Drown me in bass frequency!

Every time I look in his face
I can't stop thinking of horrible waste
Cause things aren't always how they appear
And he's not the same person as he was last year
He's got a good life, he's got a good home
He's his own victim, decisions are his own
And every time I look in his eyes
I'm seeing crisis and compromise
Cause things aren't always how they appear
And he's not the same person he was last year
He's got a good life, he's got a good home
He's his own victim, decisions are his own
