Biotech
has bamboozled us all
Studies suggest that traditional farming
methods are still the best
Special report: what's wrong with
our food?

The advice could
scarcely have come from a more surprising source. "If
anyone tells you that GM is going to feed the world,"
Steve Smith, a director of the world's biggest biotechnology
company, Novartis, insisted, "tell them that it is not...
To feed the world takes political and financial will - it's
not about production and distribution."
Mr. Smith was voicing a truth which most of his colleagues
in biotechnology companies have gone to great lengths to deny.
On a planet wallowing in surfeit, people starve because they
have neither the land on which to grow food for themselves
nor the money with which to buy it. There is no question that,
as the population increases, the world will have to grow more,
but if this task is left to the rich and powerful - big farmers
and big business - then, irrespective of how much is grown,
people will become progressively hungrier. Only a redistribution
of land and wealth can save the world from mass starvation.
But in one respect Mr. Smith is wrong. It is, in part, about
production. A series of remarkable experiments has shown that
the growing techniques which his company and many others have
sought to impose upon the world are, in contradiction to everything
we have been brought up to believe, actually less productive
than some of the methods developed by traditional farmers
over the past 10,000 years.
Last week, Nature magazine reported the results of one of
the biggest agricultural experiments ever conducted. A team
of Chinese scientists had tested the key principle of modern
rice-growing (planting a single, hi-tech variety across hundreds
of hectares) against a much older technique (planting several
breeds in one field). They found, to the astonishment of the
farmers who had been drilled for years in the benefits of
"monoculture", that reverting to the old method
resulted in spectacular increases in yield. Rice blast - a
devastating fungus which normally requires repeated applications
of poison to control - decreased by 94%. The farmers planting
a mixture of strains were able to stop applying their poisons
altogether, while producing 18% more rice per acre than they
were growing before.
Another paper, published in Nature two years ago, showed that
yields of organic maize are identical to yields of maize grown
with fertilisers and pesticides, while soil quality in the
organic fields dramatically improves. In trials in Hertfordshire,
wheat grown with manure has produced higher yields for the
past 150 years than wheat grown with artificial nutrients.
Professor Jules Pretty of Essex University has shown how farmers
in India, Kenya, Brazil, Guatemala and Honduras have doubled
or tripled their yields by switching to organic or semi-organic
techniques. A study in the US reveals that small farms growing
a wide range of plants can produce 10 times as much money
per acre as big farms growing single crops. Cuba, forced into
organic farming by the economic blockade, has now adopted
this as policy, having discovered that it improves both the
productivity and the quality of its crops.
Hi-tech farming, by contrast, is sowing ever graver problems.
This year, food production in Punjab and Haryana, the Indian
states long celebrated as the great success stories of modern,
intensive cultivation, has all but collapsed. The new crops
the farmers there have been encouraged to grow demand far
more water and nutrients than the old ones, with the result
that, in many places, both the ground water and the soil have
been exhausted.
We have, in other words, been deceived. Traditional farming
has been stamped out all over the world not because it is
less productive than monoculture, but because it is, in some
respects, more productive. Organic cultivation has been characterised
as an enemy of progress for the simple reason that it cannot
be monopolised: it can be adopted by any farmer anywhere,
without the help of multinational companies. Though it is
more productive to grow several species or several varieties
of crops in one field, the biotech companies must reduce diversity
in order to make money, leaving farmers with no choice but
to purchase their most profitable seeds. This is why they
have spent the last 10 years buying up seed breeding institutes
and lobbying governments to do what ours has done: banning
the sale of any seed which has not been officially - and expensively
- registered and approved.
All this requires an unrelenting propaganda war against the
tried and tested techniques of traditional farming, as the
big companies and their scientists dismiss them as unproductive,
unsophisticated and unsafe. The truth, so effectively suppressed
that it is now almost impossible to believe, is that organic
farming is the key to feeding the world.
