Ecological and economic
concerns
GM crops are a topic for
which one cannot complain of lack of media attention! This arises,
however, from concerns of two kinds, ecological and economic.
Most of the opposition to GM biotechnology comes, it must be said,
from well-fed citizens of developed countries.
Ecological concerns include
risks to human an animal health, food safety, and unforseen consequences
of spreading of transmuted genes into the natural environment.
Both international and private organizations are highly aware
of these concerns, and actively researching into them. To date,
no risks to health of environment have been proven.
Economic concerns are primarily
that the technology will get into the hands of private companies,
who will make profits by selling their monopoly. In the case of
rice, indica was mapped by a public consortium, but japonica by
a private company. The international agricultural research community
are holding discussions to overcome such problems.
Gene biotechnology:
the next major hope for reducing hunger
A disastrous situation,
causing untold suffering, is emerging. With the crop production
area no longer expanding since 1995 (852-855 M ha), the raising
of yields is the main hope to meet needs of an expanding, but
already
undernourished, population. But FAO statistics show that average
cereal yields in developing countries have becoming static, at
2800 kg/ha, since 1998.
GM crops are urgently needed,
as the third major technique in crop breeding, following simple
selection and hybridization. Advances are directed not just at
yield increases, but at specialized adaptations, e.g. pest resistance,
salt and drought tolerance, nitrogen fixation.
It is fortunate that the
much-publicized opposition to GM crops in the West has not halted
progress where they are most needed, in the food crops of the
greater part of the world's poor. A cartoon in Tropical Agriculture
Association Newsletter showed neolithic protesters destroying
crops labelled 'Agriculture Trial #1': "They're right to trash
it" commented a bystander, "You don't know what dangers might
arise."
As with so many advances
in food and agriculture, we have to finish with the point repeatedly
emphasized on this site and in Land Resources. GM crop
research is certainly a current priority, although it should not
be at the expense of losing sight of soil management. But anything
more than a marginal and temporary reduction in hunger can only
come if still greater efforts are made to check population increase
in developing countries.

| A comment on protesters,
from "The Times" 5 June 2002: "lf rich Westerners
don't want GM crops frankly I don't give a stuff. But if in
the process we prevent people who really need this technology
in the Third World from tetting it, then that's immoral."
