Going
Bananas
A
The
world’s favourite fruit could disappear forever in 10 years time. The banana is
among the world’s oldest crops. Agricultural scientists believe that the first
edible banana was discovered around ten thousand years ago. It has been at an
evolutionary standstill ever since it was first propagated in the jungles of
South-East Asia at the end of the last ice age. Normally the wild banana, a
giant jungle herb called Musa acuminate, contains a mass of hard seeds that
make the fruit virtually inedible. But now and then, hunter-gatherers must have
discovered rare mutant plants that produced seed-less, edible fruits.
Geneticists now know that the vast majority of these soft-fruited plants
resulted from genetic accidents that gave their cells three copies of each chromosome
instead of the usual two. This imbalance prevents seeds and pollen from
developing normally, rendering the mutant plants sterile. And that is why some
scientists believe the world’s most popular fruit could be doomed. It lacks the
genetic diversity to fight off pests and diseases that are invading the banana
plantations of Central America and the small-holdings of Africa and Asia alike.
B
In
some ways, the banana today resembles the potato before blight brought famine
to Ireland a century and a half ago. But “it holds a lesson for other crops,
too”, says Emile Frison, top banana at the International Network for the
Improvement of Banana and Plantain in Montpellier, France. “The state of the
banana”, Frison warns, “can teach a broader lesson the increasing
standardisation of food crops around the world is threatening their ability to
adapt and survive.”
C
The
first Stone Age plant breeders cultivated these sterile freaks by replanting
cuttings from their stems. And the descendants of those original cuttings are
the bananas we still eat today. Each is a virtual clone, almost devoid of
genetic diversity. And that uniformity makes it ripe for a disease like no
other crop on Earth. Traditional varieties of sexually reproducing crops have
always had a much broader genetic base, and the genes will recombine in new
arrangements in each generation. This gives them much greater flexibility in
evolving responses to disease – and far more genetic resources to draw on in
the face of an attack. But that advantage is fading fast, as growers
increasingly plant the same few, high-yielding varieties. Plant breeders work
feverishly to maintain resistance in these standardized crops. Should these
efforts falter, yields of even the most productive crop could swiftly crash.
“When some pest or disease comes along, severe epidemics can occur,” says Geoff
Hawtin, director of the Rome-based International Plant Genetic Resources
Institute.
D
The
banana is an excellent case in point. Until the 1950s, one variety, the Gros
Michel, dominated the world’s commercial banana business. Found by French
botanists in Asian the 1820s, the Gros Michel was by all accounts a fine
banana, richer and sweeter than today’s standard banana and without the
latter’s bitter aftertaste when green. But it was vulnerable to a soil fungus
that produced wilt known as Panama disease. “Once the fungus gets into the soil
it remains there for many years. There is nothing farmers can do. Even chemical
spraying won’t get rid of it,” says Rodomiro Ortiz, director of the
International Institute for Tropical Agriculture in Ibadan, Nigeria. So
plantation owners played a running game, abandoning infested fields and moving
so “clean” land – until they ran out of clean land in the 1950s and Had to
abandon the Gros Michel. Its successor and still the reigning commercial king
is the Cavendish banana, a 19th-century British discovery from southern China.
The Cavendish is resistant to Panama disease and, as a result, it literally
saved the international banana industry. During the 1960s, it replaced the Gros
Michel on supermarket shelves. If you buy a banana today, it is almost
certainly a Cavendish. But even so, it is a minority in the world’s banana
crop.
E
Half
a billion people in Asia and Africa depend on bananas. Bananas provide the
largest source of calories and are eaten daily. Its name is synonymous with
food. But the day of reckoning may be coming for the Cavendish and its
indigenous kin. Another fungal disease, black Sigatoka, has become a global
epidemic since its first appearance in Fiji in 1963. Left to itself, black
Sigatoka – which causes brown wounds on leaves and premature fruit ripening –
cuts fruit yields by 50 to 70 per cent and reduces the productive lifetime of
banana plants from 30 years to as little as 2 or 3. Commercial growers keep
Sigatoka at bay by a massive chemical assault. Forty sprayings of fungicide a
year is typical. But despite the fungicides, diseases such as black Sigatoka
are getting more and more difficult to control. “As soon as you bring in a new
fungicide, they develop resistance,” says Frison. “One thing we can be sure of
is that the Sigatoka won’t lose in this battle.” Poor farmers, who cannot
afford chemicals, have it even worse. They can do little more than watch their
plants die. “Most of the banana fields in Amazonia have already been destroyed
by the disease,” says Luadir Gasparotto, Brazil’s leading banana pathologist
with the government research agency EMBRAPA. Production is likely to fall by 70
percent as the disease spreads, he predicts. The only option will be to find a
new variety.
F
But
how? Almost all edible varieties are susceptible to diseases, so growers cannot
simply change to a different banana. With most crops, such a threat would
unleash an army of breeders, scouring the world for resistant relatives whose
traits they can breed into commercial varieties. Not so with the banana.
Because all edible varieties are sterile, bringing in new genetic traits to
help cope with pests and diseases is nearly impossible. Nearly, but not
totally. Very rarely, a sterile banana will experience a genetic accident that
allows an almost normal seed to develop, giving breeders a tiny window for
improvement. Breeders at the Honduran Foundation of Agricultural Research have
tried to exploit this to create disease-resistant varieties. Further
backcrossing with wild bananas yielded a new seedless banana resistant to both
black Sigatoka and Panama disease.
G
Neither
Western supermarket consumers nor peasant growers like the new hybrid. Some
accuse it of tasting more like an apple than a banana. Not surprisingly, the
majority of plant breeders have till now turned their backs on the banana and
got to work on easier plants. And commercial banana companies are now washing
their hands of the whole breeding effort, preferring to fund a search for new
fungicides instead. “We supported a breeding programme for 40 years, but it
wasn’t able to develop an alternative to Cavendish. It was very expensive and
we got nothing back,” says Ronald Romero, head of research at Chiquita, one of
the Big Three companies that dominate the international banana trade.
H
Last
year, a global consortium of scientists led by Frison announced plans to
sequence the banana genome within five years. It would be the first edible
fruit to be sequenced. Well, almost edible. The group will actually be
sequencing inedible wild bananas from East Asia because many of these are
resistant to black Sigatoka. If they can pinpoint the genes that help these
wild varieties to resist black Sigatoka, the protective genes could be
introduced into laboratory tissue cultures of cells from edible varieties.
These could then be propagated into new, resistant plants and passed on to
farmers.
I
It
sounds promising, but the big banana companies have, until now, refused to get
involved in GM research for fear of alienating their customers. “Biotechnology
is extremely expensive and there are serious questions about consumer
acceptance,” says David McLaughlin, Chiquita’s senior director for
environmental affairs. With scant funding from the companies, the banana genome
researchers are focusing on the other end of the spectrum. Even if they can
identify the crucial genes, they will be a long way from developing new
varieties that smallholders will find suitable and affordable. But whatever
biotechnology’s academic interest, it is the only hope for the banana. Without
banana production worldwide will head into a tailspin. We may even see the
extinction of the banana as both a lifesaver for hungry and impoverished
Africans and as the most popular product on the world’s supermarket shelves.

Can
we call it “ART” (2)
Life-Casting
and Art
Julian
Bames explores the questions posed by Life-Casts, an exhibition of plaster
moulds of living people and objects which were originally used for scientific
purposes
A
Art
changes over time and our idea of what art is changing too. For example,
objects originally intended for devotional, ritualistic or recreational
purposes may be recategorized as art by members of other later civilisations,
such as our own, which no longer respond to these purposes.
B
What
also happens is that techniques and crafts which would have been judged
inartistic at the time they were used are reassessed. Life-casting is an
interesting example of this. It involved making a plaster mould of a living
person or thing. This was complex, technical work, as Benjamin Robert Haydon
discovered when he poured 250 litres of plaster over his human model and nearly
killed him. At the time, the casts were used for medical research and,
consequently, in the nineteenth-century life-casting was considered inferior to
sculpture in the same way that, more recently, photography was thought to be a
lesser art than painting. Both were viewed as unacceptable shortcuts by the
‘senior’ arts. Their virtues of speed and unwavering realism also implied their
limitations; they left little or no room for the imagination.
C
For
many, life-casting was an insult to the sculptor’s creative genius. In an
infamous lawsuit of 1834, a moulder whose mask of the dying French emperor
Napoleon had been reproduced and sold without his permission was judged to have
no rights to the image. In other words, he was specifically held not to be an
artist. This judgement reflects the view of established members of the
nineteenth-century art world such as Rodin, who commented that life-casting
‘happens fast but it doesn’t make Art’. Some even feared that ‘if too much
nature was allowed in, it would lead Art away from its proper course of the
Ideal.
D
The
painter Gauguin, at the end of the nineteenth century, worried about future
developments in photography. If ever the process went into colour, what painter
would labour away at a likeness with a brush made from squirrel-tail? But
painting has proved robust. Photography has changed it, of course, just as the
novel had to reassess narrative after the arrival of the cinema. But the gap
between the senior and junior arts was always narrower than the traditionalists
implied. Painters have always used technical back-up such as studio assistants
to do the boring bits, while apparently lesser crafts involve great skill,
thought, preparation and, depending on how we define it, imagination.
E
Time
changes our view in another way, too. Each new movement implies a reassessment
of what has gone before? What is done now alters what was done before. In some
cases, this is merely self-serving, with the new art using the old to justify
itself. It seems to be saying, look at how all of that points to this! Aren’t
we clever to be the culmination of all that has gone before? But usually, it is
a matter of re-alerting the sensibility, reminding us not to take things for
granted. Take, for example, the cast of the hand of a giant from a circus, made
by an anonymous artist around 1889, an item that would now sit happily in any
commercial or public gallery. The most significant impact of this piece is on
the eye, in the contradiction between unexpected size and verisimilitude. Next,
the human element kicks in, you note that the nails are dirt-encrusted, unless
this is the caster’s decorative addition, and the fingertips extend far beyond
them. Then you take in the element of choice, arrangement, art if you like, in
the neat, pleated, buttoned sleeve-end that gives the item balance and
variation of texture. This is just a moulded hand, yet the part stands utterly for
the whole. It reminds us slyly, poignantly, of the full-size original.
F
But
is it art? And, if so, why? These are old tediously repeated questions to which
artists have often responded, ‘It is art because I am an artist and therefore
what I do is art. However, what doesn’t work for literature works much better
for artworks of art do float free of their creators’ intentions. Over time the
“reader” does become more powerful. Few of us can look at a medieval altarpiece
as its painter intended. We believe too little and aesthetically know too much,
so we recreate and find new fields of pleasure in the work. Equally, the lack
of artistic intention of Paul Richer and other forgotten craftsmen who brushed
oil onto flesh, who moulded, cast and decorated in the nineteenth century is
now irrelevant. What counts is the surviving object and our response to it. The
tests are simple: does it interest the eye, excite the brain, move the mind to
reflection and involve the heart. It may, to use the old dichotomy, be beautiful
but it is rarely true to any significant depth. One of the constant pleasures
of art is its ability to come at us from an unexpected angle and stop us short
in wonder.

PASSAGE 3
You
should spend about 20 minutes on Questions 27-40 which are based on
Reading Passage 3 below.
Global
Warming in New Zealand
A
For
many environmentalists, the world seems to be getting warmer. As the nearest
country of the South Polar Region, New Zealand has maintained an upward trend
in its average temperature in the past few years. However, the temperature in
New Zealand will go up 4oC in the next century while the polar region will go
up more than 6oC. The different pictures of temperature stem from its
surrounding ocean which acts as the air conditioner. Thus New Zealand is
comparatively fortunate.
B
Scientifically
speaking, this temperature phenomenon in New Zealand originated from what
researchers call “SAM (Southern Annular Mode), which refers to the wind belt
that circles the Southern Oceans including New Zealand and Antarctica. Yet
recent work has revealed that changes in SAM in New Zealand have resulted in a
weakening of moisture during the summer, and more rainfall in other seasons. A
bigger problem may turn out to be heavier droughts for agricultural activities
because of more water loss from soil, resulting in the poorer harvest before
winter when the rainfall arrives too late to rescue.
C
Among
all the calamities posed by drought, moisture deficit ranks the first. Moisture
deficit is the gap between the water plants need during the growing season and
the water the earth can offer. Measures of moisture deficit were at their
highest since the 1970s in New Zealand. Meanwhile, ecological analyses clearly
show moisture deficit is imposed at the different growth stage of crops. If
moisture deficit occurs around a crucial growth stage, it will cause about 22%
reduction in grain yield as opposed to moisture deficit at the vegetative
phase.
D
Global
warming is not only affecting agriculture production. When scientists say the
country’s snowpack and glaciers are melting at an alarming rate due to global
warming, the climate is putting another strain on the local places. For
example, when the development of global warming is accompanied by the falling
snow line, the local skiing industry comes into a crisis. The snow line may
move up as the temperature goes up, and then the snow at the bottom will melt
earlier. Fortunately, it is going to be favourable for the local industry to
tide over tough periods since the quantities of snowfall in some areas are more
likely to increase.
E
What
is the reaction of the glacier region? The climate change can be reflected in
the glacier region in southern New Zealand or land covered by ice and snow. The
reaction of a glacier to a climatic change involves a complex chain of
processes. Overtime periods of years to several decades, cumulative changes in
mass balance cause volume and thickness changes, which will affect the flow of
ice via altered internal deformation and basal sliding. This dynamic reaction
finally leads to glacier length changes, the advance or retreat of glacier
tongues. Undoubtedly, glacier mass balance is a more direct signal of annual
atmospheric conditions.
F
The
latest research result of National Institute of Water and Atmospheric (NIWA)
Research shows that glaciers line keeps moving up because of the impacts of
global warming. Further losses of ice can be reflected in Mt. Cook Region. By
1996, a 14 km long sector of the glacier had melted down forming a melt lake
(Hooker Lake) with a volume. Melting of the glacier front at a rate of 40 m/yr
will cause the glacier to retreat at a rather uniform rate. Therefore, the lake
will continue to grow until it reaches the glacier bed.
G
A
direct result of the melting glaciers is the change of high tides that serves
the main factor for sea-level rise. The trend of sea-level rise will bring a
threat to the groundwater system for its hypersaline groundwater and then pose
a possibility to decrease agricultural production. Many experts believe that
the best way to counter this trend is to give a longer-term view of sea-level
change in New Zealand. Indeed, the coastal boundaries need to be upgraded and
redefined.
H
There
is no doubt that global warming has affected New Zealand in many aspects. The
emphasis on global warming should be based on the joints efforts of local
people and experts who conquer the tough period. For instance, farmers are
taking a long term, multi-generational approach to adjust the breeds and
species according to the temperature. Agriculturists also find ways to tackle
the problems that may bring to the soil. In broad terms, going forward, the
systemic resilience that’s been going on a long time in the ecosystem will
continue.
I
How
about animals’ reaction? Experts have surprisingly realised that animals have
an unconventional adaptation to global warming. A study has looked at sea
turtles on a few northern beaches in New Zealand and it is very interesting to
find that sea turtles can become male or female according to the temperature.
Further researches will try to find out how rising temperatures would affect
the ratio of sex reversal in their growth. Clearly, the temperature of the nest
plays a vital role in the sexes of the baby turtles.
J
Tackling
the problems of global warming is never easy in New Zealand because records show
the slow process of global warming may have a different impact on various
regions. For New Zealand, the emission of carbon dioxide only accounts for 0.5%
of the world’s total, which has met the governmental standard. However, New
Zealand’s effort counts only the tip of the iceberg. So far, global warming has
been a world issue that still hangs in an ambiguous future.
