Bananas are
the world's fourth largest staple crop and they provide a livelihood for
half a billion people. Nearly 100 million tons are grown annually and half
a billion people depend on them.
Westerners eat only the 15% of the crop which are sweet dessert bananas
The
banana is, after all, an ideal food. At least one imaginative creationist
has seriously suggested that its near-perfect design is evidence of God's
existence.
It is ergonomically shaped to fit the human hand, with a non-slip
surface. It has an outward indicator of ripeness—green, yellow and
black. Its disposable wrapper has a tab at one end for removal and
perforated edges for easy peeling. Add the fact that the banana has a
pointed end and curved shape for easy entry into the mouth, and who could
argue that it was indeed an act of divine inspiration? Banana
is the only raw fruit permitted for people suffering from gastric ulcer,
and is also recommended for infantile diarrhea. Banana is also used as a
source of carbohydrate in coeliac disease and in the relief of colitis.

Going
Bananas
I strongly believe that bananas, along with coconuts, taro
and seafoods, gave the ancient peoples of my island, together with others
spread all along the coasts of South East Asia and the Indian Ocean,
where many settled after thousands of years strandloping along the
beaches, an absolutely ideal pre-agricultural diet. It was certainly a
great deal better than the rice-based food which pervades the region today.
Bananas almost certainly originated in South-East Asia, and
perhaps in the Southern Philippines/Borneo region.
Until I started this study (I have only been 'on-site' and
thinking about it for about a month now) all I knew about bananas was a
WWII song 'Yes, We Have No Bananas' and articles such as the one
below. Then, just a week ago, I had some boiled sweet local bananas
for breakfast, and nearly broke a tooth on their peppercorn seeds.
(Bananas don't have seeds, as anyone will tell you). I also remembered an
argument with my neighbour, who chopped down my own rampant
banana tree, that had mysteriously grown from nothing. I asked some of my research team how many varieties of local
bananas and plantains there were available on the island. They came up with an initial list of 12:
Estampilko
Lakatan
Litungdan
Sab-a*
Karnaba
Pelipita
Manila
Bungoyan*
Paguha
Tundanon
Tindok*
Tumbaga*
Having done the theory bit, I despatched the 'banana crew'
out to the wilds of the island to find as many varieties as were
available. So far, we have 8 of the 12.

Lack
of Sex Life Threatens Banana Crops !
! ! !
Steve
Conner - The Independent (London)
July 27, 2001
The banana's sex life—or lack of it—is cause for growing concern to
farmers and scientists.
The domestic banana that we know and love is an asexual clone, one
that results from the sedate, artificial act of vegetative propagation.
And no pollinated sex means no annoying seeds, which may be good news for
hungry consumers but also means that there's little or no genetic
variation—and hence little or no resistance to the banana's many natural
enemies
Devoid of sex, the poor cloned banana is a sitting target for any pest.
Finding a way of introducing a little spice—and therefore genetic
variety—into the reproductive life of the banana (and its cousin the
plantain) is therefore a pressing problem.
That's why a project to do just that has now begun. Announced recently, it
involves scientists from 11 countries forming a consortium to decode the
banana's genome within the next five years.
As with the human genome project, the information will reveal much about
the genes that make a banana what it is, and more importantly what it
might be with a little extra help. This information—and any resulting
advances in genetic modification—will be of profound importance, not
just to banana boffins, but to a large proportion of humanity.
The banana is the world's fourth largest staple crop, one on which the
livelihoods of half a billion people depend. But, recently, an
evil-sounding beast called the Black Sigatoka fungus has been
throwing those livelihoods into jeopardy.
Black Sigatoka, along with the weevils, worms and viruses that also
routinely attack bananas, is a particularly disturbing menace in the
tropics, where the cooking banana and starchy plantain provide up to a
quarter of the daily intake of essential calories.
Only the banana plantations supplying the lucrative export markets can
afford the expensive pesticides and fungicides to defend their crops. For
many subsistence farmers, an attack of Black Sigatoka means disaster, and
sometimes even starvation.
"Resistant strains are essential for small-holder farmers, who cannot
afford the expensive chemicals to begin with," says Emile Frison,
director of the International Network for the Improvement of Banana and
Plantain (Inibap), the French-based organization that is helping to run
the banana genome project. "When Black Sigatoka strikes, farmers can
do little more than watch their plants die. Increased hunger can swiftly
follow."
The sweet dessert bananas that all Westerners know are big business,
but they only account for about 15 percent of the 95 million tons of
bananas grown annually.
The
vast bulk of the banana family is made up of the starchy cooking bananas
and plantains grown as a staple.
But all the minor varieties of cultivated banana are essentially sterile,
genetically uniform clones. The banana varieties that do exist have come
about not through the normal process of genetic shuffling that occurs
during sexual reproduction, but by mutations within a clone that are
vegetatively propagated by taking cuttings or "suckers" growing
from the base of the plant.
How the banana has got away without sex for so many thousands of years
owes much to the hand of man. Although wild bananas do pollinate their
flowers—having the botanical equivalent of sex—their fruit is packed
full of peppercorn-hard seeds, making them inedible.
The soft, yellow flesh of the edible varieties is the result of a mutation
many thousands of years ago that rendered the fruits of these plants
sterile. Being sterile, of course, is a major handicap in the wild—which
is why the banana would not be where it is today without being propagated
and carried there by humans.
There is, in fact, nothing very natural about the banana, which would have
remained an obscure plant confined to somewhere in India or Malaysia had
it not been for the Stone Age farmer who took a fancy to the fruit of its
sterile mutant and propagated the first cutting from one of the suckers.
From Asia, prehistoric humans are thought to have taken suckers to Africa,
where it quickly spread by further vegetative propagation.
The Story
of the Banana
Just how important humans have been to the banana is best illustrated by
the story of the Cavendish variety, the one that accounts for about
nine out of every ten bananas sold in British shops.
The story starts in southern China, in 1826, when Charles Telfair, a plant
collector and resident of Mauritius, took a fancy to some banana plants he
had spied on his travels. Three years later, he sent a pair of them to a
friend in England. On this friend's death, they were sold to the Duke of
Devonshire, who grew them successfully in his glasshouses at Chatsworth
House. The variety was formally named in 1836 after the Duke of
Devonshire's family name, Cavendish.
From Chatsworth, horticulturalists spread the Cavendish variety far and
wide, always by vegetative propagation of the suckers. John Williams, a
missionary, took suckers from Chatsworth to Samoa, the Friendly Islands
and Fiji. It is supposed to have reached Hawaii via Tahiti in 1855, at
about the same time that it was brought to Australia and Papua New Guinea.
Spanish missionaries are also thought to have taken the other varieties
from the Canary Islands (where they may have been introduced by French
missionaries who had been to China), to the Caribbean, and to Central and
South America.
The banana is, after all, an ideal food. At least one imaginative
creationist has seriously suggested that its near-perfect design is
evidence of God's existence.
It is ergonomically shaped to fit the human hand, with a non-slip
surface. It has an outward indicator of ripeness—green, yellow and
black. Its disposable wrapper has a tab at one end for removal and
perforated edges for easy pealing. Add the fact that the banana has a
pointed end and curved shape for easy entry into the mouth, and who could
argue that it was indeed an act of divine inspiration?

More seriously, however, the banana represents the fine line between life,
misery and death for millions of people. "You have to understand how
fundamentally important the banana is to many parts of the world,"
says James Ferguson, a renowned historian of the Caribbean. "They are
an absolute lifeline for poor communities across the world. You can grow a
plant outside your house and it's a reliable source of carbohydrates. They
are especially good in hurrican-prone countries because they can be grown
from nothing to bear fruit in just nine months."
The advent of mass refrigeration in the early 20th century meant it became
economically viable to export the fruit from the "banana
republics" of the tropics to the United States and, later on, Europe.
The banana became a symbol of post-war prosperity, being a much
sought-after fruit during and after rationing. Bananas were also the first
thing East Germans wanted to buy after the Wall came down in 1989.
These days, European countries alone munch their way through about 2.5
million tons of bananas each year. About 7 percent of this trade comes
from the Caribbean, thanks to special trading relations that date back to
colonial times. The remaining trade is largely with Latin America, where
U.S. multinational interests are able to afford chemical fertilizers and
pesticides that help produce bigger, cheaper, but less environmentally
sound bananas.
Banana Wars
The dessert banana, which accounts for less than 15 percent of global
production, has recently been the focus of a bitter trade war between the
United States and Europe. American interests in Latin America wanted the
European Union to loosen its relationship with the Caribbean. An
all-out banana war was only averted this year (2001) when the E.U. promised to
change its quota system, which favored the Caribbean, by 2006.
But talk of banana wars mean little to the millions of people who see the
banana and plantain as an essential part of their everyday diet rather
than an after-dinner treat. "More than a popular snack, bananas are a
staple food that many African families eat for every meal," says Dr.
Frison of Inibap. Rich in vitamins A, C and B6, bananas also contain
high levels of calcium, potassium, and phosphorus.
For the past 30 years, however, Black Sigatoka, has been undermining this
rich source of sustenance. The fungus has now spread to almost every
banana-growing region in the world and typically reduces yield by between
30 and 50 percent.
Commercial varieties of bananas rely extensively on repeated spraying,
sometimes drenching the crop up to 50 times a year. This is about ten
times greater than the average amount of agrochemicals used on intensively
grown crops in industrialized countries.
Unraveling the genes on each of the banana's 11 chromosomes might reveal a
genetic solution to the problem of disease, Frison says: "If we can
devise resistant banana varieties, we could possibly do away with
fungicides and pesticides altogether."
Tapping the genetic variety of the wild, sexually active varieties of the
plant may help to maintain the "top banana" status of the fruit.
It is a long way from the time when Alexander the Great was said to have
been the first European to discover the banana, when he witnessed Indian
sages eat a yellow, crescent-shape fruit suspiciously resembling the
modern-day wonder. Improving on nature, however, is what the banana has
relied on for it phenomenal success and ubiquity.
Where would we be without the banana? And, equally, where would the banana
be without us?

What's
wrong with Nutrition Charts
You
can prove almost anything with statistics, and this kind of table is no
exception. You can grow a whole lot of camote in a small field (or even
more rice) – bananas need space, but they will grow almost anywhere on
the most marginal of lands. And they need virtually no ‘cultivation’,
no labour, no fertilisers, no irrigation, nor any of the other inputs needed for
‘staple’ crops. So the input for bananas should really be matched and
compared with the output - as a really 'economical'crop it would compare
very favourably indeed with, say rice or wheat.
You
can grow bananas as a monoculture, but you can’t harvest them
mechanically – you still need the Harry Belafontes of this world to pick
them and load them, so they cannot be a major
automated crop, like wheat or soy beans, easily put on the world commodities and futures markets,
and easily swamped by the West’s agro-industries.
This
table (and the others) compares staple carbohydrate foods as if they were
eaten in the same quantities, with the same amount of preparation and
farming input, and ignore the protein foods normally eaten with them.
Why
So Many Pacific Islanders Are Obese Alcoholics
Although
Pacific peoples seem to be genetically predisposed to obesity, diabetes,
cardiovascular disease, and gout (Baker 1979), the main cause of the
increase of these diseases today seems to be the shift to a diet of
imported, highly refined foods from a diet of fresh foods high in fibre,
vitamins, and minerals and low in sugar, salt, animal fats, and refined
carbohydrates. A diet based on imported, highly refined foods is the
reverse - as well as containing carcinogenic food additives. Table 3 is an
attempt to assess the degree of correlation between these dietary changes
and the major nutritional and nutritionrelated disorders. Cigarette
smoking, increasing alcohol consumption, and decreasing physical activity
are also contributing factors to the rising incidence of such diseases
(Coyne 1984; Thaman 1983a).
The fresh fruits, nuts, vitamin-rich green leaves, derived juices, and
complex-carbobydrate-rich and fibre-rich staple foods such as bananas,
breadfruit, and even coconut (which has no animal fat or cholesterol, and
the high Pacific-islander consumption of which does not seem to be
correlated with the increase in any of these diseases, except possibly
gout and hyperuricaemia) are exactly the types of foods needed to stem the
Pacific's dangerous nutritional transformation. These foods also
constitute the traditional snacks, drinks, and supplementary foods that
are now being replaced by soft drinks, candy, and other modern but
nutritionally-poor processed foods. Source

Comment: Most
of the above comments apply to pampered island natives from American,
French, or British colonies in the South Seas, where Coco-Colonisation has
been most successful, or, as in a few tragic cases, where bird-shit
(guano) has been found or somebody in Washington, London, or Paris has
decided to try out a few nuclear arms.
My island is quite different; so isolated that hardly any Spanish or
Americans ever came there, and the only direct foreign occupation was by
Japanese in WWII, who behaved themselves and were welcomed. There are no
obese natives here (except for Jade, who is ginormous, and probably has sumo
genes).

Don’t
Waste Anything !
Puso ng saging,
the banana flower, makes a delicious salad. Weighing about half a kilo,
each flower can easily provide a salad for quite a large family, and are
almost free; there are so many bananas around that anyone can take them
from ‘the wild’.
They're somewhat like an endive (chicory). You take
off the outer husk; then just slice them; they’re crisp and
delicious.

They’re also very sexy. It’s no coincidence that Georgia O’Keeffe,
the doyenne of flower painters, who could paint any flower into an erotic
dream, drew, in 1933, with charcoal only, the four sketches which
illustrate this section. (I have added a picture by her of a tobacco
flower; not because it has anything to do with bananas, but because it
perfectly shows her ability to turn a humble flower into a sex-bomb).

Then there’s the ubod
– the core of the banana tree stem. Each tree has about 10 kilos of
core, about the consistency of potato; again, you can eat it raw, or
cooked like potato. It is so common, though, that most people use it as a
basic pig food.
To grow a new banana tree, all you need is one of the
suckers that grow out from the base stem of the parent tree. Cut it off,
plant it in damp ground, and forget it until you are ready for harvest.
Some of our local bananas, like pelipita
or paguha, have seeds about the
size of a peppercorn that can be sown to produce a tree.
And, of course, the leaves make perfect dishes or
place mats; or even umbrellas in the rainy season. The background to this
web page is a banana leaf.
And there's more - I
make jewellery from this plant - wait and see some more pictures.
