articlehighlights GM crops are to some an
answer to world hunger. To others, these crops are
a health risk and an environmental threat because
some GM crops: |
- have proven to be
genetically unstable
- do not do what they were
designed to do
- are a risk to human
health, particularly children
- cause animals who eat
them to become immune to
antibiotics
- spread and destroy

Biotechnology in Crops:
Issues for
the Developing World Compiled by Laura Spinney for Oxfam
GB |
|
Many GM crops are not
field tested or regulated in the
U.S.
|
In 1997, 30 million acres worldwide
were planted with genetically modified (GM) crops.
Almost 15 percent of the 1997 US soya harvest was
grown from GM seed and China is thought to be
growing over four million acres of GM tobacco and
tomatoes. Twenty-three GM crop varieties have
reached the stage where strict regulations are no
longer required for field testing in the US. Until
last year, most commercial transgenic crops were
engineered for single gene traits, mostly
herbicide tolerance and pest resistance. But in
1997, for the first time, crops were marketed with
"stacked gene traits," i.e., more than one
engineered trait in a single variety.
|
| Most GM crops are
engineered to fight pests, improve nutrition, or
to prevent disease or pollution. |
Likely future developments
include:
- Continued development of
herbicide-tolerant, virus- and pest-resistant
crops.
- Methods to speed up traditional plant
breeding.
- Further development of fruit and
vegetables in which the production of ethylene
is suppressed so that they take longer to
ripen.
- Modification of oils, fats and starches
to improve processing or dietary
characteristics.
- Improvement of flavour, texture,
bio-absorbability, nutritional content and
elimination of genes for toxic substances and
allergens.
- Identification of genes controlling salt
tolerance, resistance to drought, flood, and
extreme temperatures, and response to day
length.
- GM crops that fix nitrogen with greater
efficiency, thereby reducing the need for
fertilizers.
- GM plants that produce vaccines or
therapeutic agents.
- GM biodegradable plastics grown in plants
such as oilseed rape could begin to replace
plastics from fossil fuels within a
decade.
- GM plants for bioremediation, i.e.
removing toxic chemicals and agrochemical
residues from the soil.
|
The top argument
used by GM proponents: GM crops will feed the
world's growing population.
|
The UN Food and Agriculture Organisation
(FAO) estimates that food output must increase by
60 percent over the next 25 years to keep up with
demand. In a report on the bioengineering of crops
written for the World Bank and the Consultative
Group on International Agricultural Research
(CGIAR) in October last year, a group led by Henry
Kendall, chair of the Washington DC-based Union of
Concerned Scientists, said that transgenic crops
could improve food yields by up to 25 percent in
developing countries and could help to feed an
estimated additional three billion people over the
next 30 years.
|
The U.S. is one of the
few nations that allow life forms to be
patented.
|
In terms of major food crops, maize and
soya have been the targets of most genetic
manipulation to date. Wheat and rice are a little
more complicated, but GM versions of these already
exist -- they are not far behind. It is possible,
therefore, that the maize- and soybean-growing
areas of the world will see the first effects of
the "biotech revolution."
|
|
Biopiracy and patents
on GM crops are providing new riches to biotech
firms. |
Socioeconomic impact
At a
meeting of the UK Food Group in April, … Indira
Jaising of the Supreme Court of India noted a
trend in TNCs (transnational companies) such as
pharmaceuticals moving from the developing world
to the US, with the contingent drain of capital,
because the US allows patenting of life forms.
Whether or not the rest of the world falls in line
with the US in accepting life patents, researchers
predict that with advances in biotechnology there
will be a switch in centers of production away
from the developing world, accompanied by loss of
export income. For example:
- Rapeseed engineered to produce lauric
acid, which is used in soap and cosmetics, is
already being grown commercially and the lauric
acid sold to Procter & Gamble, one of the
world's largest buyers of the substance. Lauric
acid is traditionally derived from coconut and
palm kernel oils produced in the tropics. The
Philippines, the world's largest exporter of
coconut oil, accounts for around two thirds of
global exports. The coconut industry also
provides employment for about 30 percent of the
county's population.
- Farmers in the US are expected to plant
twice as much GM soybean in 1998 as in 1997, and
with resistance to GM soya in Europe, there are
concerns that it will be dumped in countries
like India [which has a good harvest of its
own].
- In April, the Africa News Service
reported that tomato growers in Kenya will soon
have access to the longer-ripening FlavrSavr
tomato, provided it meets Kenya's safety
measures and guidelines on biotechnology
transfer.
|
|
Corporations that
patent crop plants often don't allow nations,
where these crops are indigenous, to
benefit.
|
Property rights -- control of
knowledge
There are various issues to
be considered here, but the central, over-arching
debate (or lack of debate) concerns ownership of
resources and how to reconcile the rigid,
individualistic patenting system of the developed
world with the community-held knowledge systems of
poorer countries.
1. Food security If foreign
researchers and TNCs can patent indigenous crop
plants without making recompense to the
communities who provided them, there are fears
that farmers will end up paying royalties on the
products of their own knowledge, products on which
they rely for survival. The following are examples
of such patents:
- In 1994, two researchers from the
University of Colorado received US patent number
5,304,718 on male sterile plants of the
traditional Bolivian 'Apelawa' quinoa variety.
They claim they were the first to identify and
use a reliable system of cytoplasmic male
sterility in quinoa for the production of
hybrids, although Andean farmers have long known
that the male flower of the Apelawa variety is
sterile. Quinoa is a high protein cereal and an
important dietary component in Andean countries.
The value of Bolivia's export market is
estimated at about US$1 million per annum. The
US patent claim covers any quinoa hybrid that is
derived from 'Apelawa' male sterile cytoplasm,
including, but not limited to, some 36
traditional varieties cited in the patent
application.
- In September 1997, the US company
Ricetec, Inc., was granted a patent on Basmati
rice. The patent is for a variety achieved by
the crossing of Indian Basmati with semi-dwarf
varieties, and it covers Basmati grown anywhere
in the Western hemisphere. Ricetec can also put
its brand on any breeding crosses involving 22
farmer-bred Basmati varieties from Pakistan and,
according to RAFI [Rural Advancement Foundation
International], on any blending of Pakistani or
Indian Basmati strains with the company's other
proprietary seeds. Ricetec also claims the right
to use the Basmati name. The Indian government
has challenged Ricetec's claim, arguing that the
patent jeopardizes India's annual Basmati export
market of around US$277 million, and threatens
the livelihood of thousands of Punjabi
farmers.
|
Monsanto, a biotech
firm, does not allow farmers to save seeds,
forcing them to continually buy more Monsanto
seed. |
The ability of farmers to save seed is seen
as crucial to food security. According to RAFI, up
to 1.4 billion poor farmers in the developing
world depend on saved seed and seeds exchanged
with farm neighbours, and up to 50 percent of
soybean in the developing world is planted with
farmer-saved seed.
- TNCs such as Monsanto require farmers who
buy their GM seeds to sign contracts agreeing
not to save seed. In March 1998 RAFI reported
that Monsanto had taken legal action against
more than 100 soybean growers in the US, and had
hired Pinkerton investigators (hired police) to
identify those saving seeds.
- In 1997, Farmers' Weekly reported that
the Biotechnology Working Party of the National
Farmers' Union (NFU) in the UK was seeking legal
advice on the status of contracts between
farmers and agrochemical firms under UK law.
British farmers were reported to be unhappy with
the US-style technology fees, licenses and
contracts for GM crops.
- In 1998 the US Department of Agriculture
and the Mississippi-based Delta and Pine Land
seed company were granted a patent on the
so-called "terminator technology", which
involves engineering seeds so that they do not
germinate if planted for a second time.
|
|
Corporations are guilty
of trying to patent plants that are an economic
staple to some nations. |
2. Bioprospecting -- biopiracy In
a report prepared by RAFI for the United Nations
Development Program in 1994, it estimated that
biopiracy of plant genetic resources and knowledge
cost developing countries $4.5 billion per annum.
Most bioprospecting to date has been carried out
for the pharmaceutical industry, but in the future
it is expected to play a greater role in research
for GM crop plants. The following are some
examples to date:
- In April 1997, two Australian government
agencies applied for patents on two strains of
chickpea, samples of which they had borrowed
from the International Crops Research Institute
for the Semi-Arid Tropics (ICRISAT) at
Hyderabad. ICRISAT subsequently told the
Australian agencies that it would be wrong to
patent plants that should be owned universally,
and on 13 January 1998 they withdrew their
applications.
- W.G. Grace & Co. [was granted] a
series of patents on extracts from the neem
tree, whose seeds and bark have been used for
centuries in India for natural pesticides. Grace
has estimated that the global market for the
pesticide could reach US$50 million a year by
2000, and while there are no hard statistics on
the impact on Indian farmers to date … [but]
farmers in the south of India, where neem is
harvested, are already losing out because the
processing and exporting of the seeds and oil is
no longer available to them.
- In 1995, two Mississippi doctors were
granted a patent for the traditional use of
turmeric as a healing powder. India's Council of
Scientific and Industrial Research (CSIR)
petitioned the US Patent and Trademark Office
(PTO) on the grounds that the 'discovery' was
not original, but had been chronicled in
traditional Indian texts. In August last year,
the PTO rejected the patent holders'
claims.
|
| Business is storing
seeds from around the world in
genebanks.
|
3. Conservation -- sustainable
agriculture International genebanks for
seed samples were originally set up in response to
concerns about the loss of genetic diversity.
Essentially they are vast refrigerators where seed
samples are stored under controlled humidity and
temperature conditions. But apart from issues of
biopiracy there are practical problems with these
genebanks:
- many of the seeds lose viability because
they are not grown out regularly,
- they are poorly catalogued and costly to
run,
- and their material may not be accessible
to farmers.
|
| Corporations claim
genebanks will help feed the worlds for several
hundred years. |
In recent years, there has been a push
towards on-farm conservation, and farmer-scientist
partnerships are being encouraged in countries
including Ethiopia, the Philippines and Chile.
Over the last few years research has brought to
light highly innovative, informal systems of
agricultural research being carried out by
indigenous farmers in developing countries. But
landraces [primitive cultivar of crops] are not
fixed. They shift with evolution to suit local
conditions, and although many TNCs claim that the
genebanks will provide them with all the basic
genetic material they need to feed the world for
the next 200 years, over a longer, evolutionary
timeframe they may need to draw on
landraces. |
|
Bt crops have proven to
be unstable and
ineffective.
|
Environmental health
impact
Examples of the impact [on the
environment] to date:
1. Bt [genetic
manipulation through biotechnology]
- Research at the University of Hawaii has
shown that insects which survive Bt transmit
genetic resistance to their immediate offspring.
If Bt becomes useless as an implanted pest
control strategy within one insect generation,
as this suggests, then organic farmers, who have
been using it effectively since the 1940s, will
be robbed of a valuable biopesticide. Regional
cases of Bt resistance have already been
reported.
- In April, Greenpeace International
demanded an urgent European ban on Novartis'
Bt-maize (which was approved by the EC in 1996)
after Swiss research showed it kills insects
other than the European corn borer, which it is
meant to target.
- George Stuber of Greenpeace in Sweden
reports that in June 1996 Monsanto planted
Bt-potatoes (containing a marker gene for the
antibiotic canamicin) in three regions of
Georgia, in the former Soviet Union. Georgia
lacks any proper legislation controlling the
release of Genetically Modified Organisms
(GMOs). The crops were devastated by fitoptora
disease because, says Stuber, the potatoes were
not adapted to the local climate.
- Similarly, GM FlavrSavr tomatoes were
grown in Guatemala, which has hundreds if not
thousands of indigenous varieties of tomato,
without the consent or knowledge of the
authorities. Although the tomatoes were grown in
greenhouses, Stuber says there is no way of
knowing how rigorously they were contained, and
there is no information as to whether the
transgenic tomatoes spread beyond those
sites.
|
Herbicide-tolerant GM
crops are proving a human and animal health
risk.
|
2. Chemical herbicides Glyphosate
is the world's best-selling "total" herbicide. It
was developed by Monsanto in the early 1970s and
its major formulation is Roundup. Largely due to
the introduction of Roundup Ready crops, human and
environmental exposure to the herbicide is
expected to increase.
- In health terms, say Friends of the
Earth, experiments have shown damaging and long
lasting reproductive effects of glyphosate on
laboratory animals. In 1995, a study in the
Journal of Environmental Science and Health
showed that exposure to glyphosate was
associated with reduced semen quality, volume
and concentration in rabbits.
- Herbicide-tolerant members of the bean
family produce higher levels of plant oestrogens
when grown in the presence of the herbicide, and
there is a risk that these could disrupt the
developing reproductive systems of children who
consume them.
- In 1994 a report by the World Health
Organisation's (WHO) International Program on
Chemical Safety found that glyphosate residues
in animal feeds arising from pre-harvest
glyphosate treatment of cereals may result in
low residues in meat, milk and eggs.
|
| It's impossible to tell
some GM crops apart from their natural
version. |
3. Antibiotic
resistance Novartis' Bt-maize contains a
marker gene which codes for antibiotic resistance
in E. coli. There is a risk that if animals or
humans consume Bt-maize-based products such as
cattle feed or starch, some antibiotics would be
rendered useless.
4. Nutritionally enhanced crops …
when crops such as rice and rapeseed with high
Vitamin A concentrations are planted, there will
be no way to distinguish them from normal rice,
with the contingent risk of liver damage if too
much Vitamin A is consumed.
5. Unpredictable crops Monsanto
is facing an increasing number of lawsuits as
their GM plants are not behaving as intended. In
1997 farmers who grew Monsanto's
herbicide-tolerant cotton saw the cotton balls
fall off their crops … In 1996, Monsanto's
pest-resistant Bt-cotton succumbed to a heat wave
in the southern US and was destroyed by bollworms
and other pests. |
|
Monoculture -- farming
only one crop -- has often eradicated other
varieties of the crop. |
6. Monocultures Most
researchers agree that biotechnology in crops will
exacerbate the trend towards monocropping set in
train by the Green Revolution, with all the
problems that that entails, e.g., higher risk of
disease and pest damage.
- Jonathan Rigg, a researcher in
agricultural development and rural change at
Durham University, cites one example from the
Green Revolution: in the late 1970s, vast areas
of Indonesia planted with a single variety of
rice were devastated by the brown plant hopper,
an event which has been linked to a subsequent
mini famine on Lombok.
- In 1996 the FAO reported that the world
depends on too few crops and that many thousands
of genetic varieties (landraces) have been lost,
mainly due to the spread of modern commercial
agriculture. The report lists the main causes of
plant genetic erosion in 154 countries, and in
over 80 of them, "replacement of local
varieties" came top. In maize, for instance,
Costa Rica, Chile, Malaysia, Philippines and
Thailand have documented widespread genetic
erosion due to monocropping.
- "What has been almost entirely overlooked
is that throughout that vast continent [of
Africa] can be found more than 2000 native
grains, roots, fruits and other food plants.
These have been feeding people for thousands of
years but most are being given no attention
whatever today." [US National Research Council,
1996]

Top biotech
players
Consolidation is taking place
throughout the global economy. 1996 saw a record
volume of mergers and acquisitions and that record
had already been shattered for 1997 before the end
of the year. According to GRAIN, "Virtually all of
the top specialist ag-biotech companies have been
absorbed, controlled or are have come under the
influence of one or more of the previously
controlling transnational (TNC) stock holders in
agriculture." The top ten agrochemical
corporations accounted for 82% of all agrochemical
sales in 1996. |
