Following the arguments of Nguyen Ngoc Hai (Monitor No. 34), organic agriculture in developing countries is in need of modern biotechnologies, such as genetic engineering. According to Vanaja Ramprasad, the justification emanates from the issue of overpopulation and, therefore, exclusively emphasizes the quantity of food production. A reductionist approach however, based on the modification of organisms on a molecular level is detrimental to ecologically and socially sustainable food production in developing countries.
One of the biggest myths perpetuated by the advocates of modern biotechnologies
is that these technologies, and especially genetic engineering, are likely
to provide a solution to world hunger. But will they really?
While technology per se is lauded as bringing relief to life’s
drudgery, it also carries social, economic and ecological costs. This side
effect of technological development has become obvious with the advent
of the Green Revolution which has led to a decrease in biodiversity and
an increase in pesticide use. As the miracle of stability in food production
is fading out, biotechnology and genetic engineering are heralded as chemical
free solutions to the problems created by the technology of the Green Revolution.
The long history of fermented foods in various parts of the world prove
that biotechnology is not a recent science. The same holds true for the
application of microorganisms such as symbiotic nitrogen fixing bacteria
and mycorrhizal fungi in biofertilizers. Farmers have been using compost,
waste material that is degraded by microorganisms, as fertilizers for centuries.
However, one has to distinguish clearly such age old methods that are now
classified under biotechnology and the new genetic engineering derived
from disciplines such as biology, biochemistry and genetics.
Yet another area in which biotechnology plays a major role is in the
selection and breeding of crops. But while the basic need is to conserve
and improve hardiness, nutritional value and yield of diverse crops used
by the poor, the dominant research focuses on, for instance, gene transfer
for pesticide resistance.
Herbicide resistance furthermore excludes the possibility of rotational
and mixed cropping that are the basis of sustainable and ecologically balanced
forms of agriculture and food security. These traditional cropping patterns
have also helped in pest control. Since many of the pests are specific
to particular plants, planting different crops in different seasons and
different years causes large reductions in pest populations. Such cropping
systems require less irrigation, which has been found to prevent the spread
of the pests.
Hai talks in his article about drought tolerant varieties which could
be developed through biotechnology. On the other hand farmers have contributed
to the genetic diversity and the dynamic conservation of land races. The
informal system has relied on the skills of farmers in maintaining, enriching
and utilizing crop diversity. The main selection criteria are yield and
yield stability, risk avoidance, low dependence on external inputs and
a range of factors associated with storage, cooking and taste.
There are several more arguments to give evidence to the fact that
organic agriculture should be free of genetic engineering. This technology
basically changes the genetic make up of plants and animals within the
confines of a laboratory. The transgenic experiments involve the transfer
of genes from one species to another, which is not the normal process in
their natural environment. If genetically engineered food is offered as
chemical free and therefore organic, it will pave the way to undermine
the very concept of organic agriculture.
One of the several arguments against genetic engineering clearly points
out that a gene is not an easily identifiable and tangible object (see
also Monitor No. 23). It is not only the DNA sequence which determines
its functions in the organism, but also its location in a specific chromosomal,
cellular, physiological and evolutionary context. It is therefore difficult
to predict the impact of genetic material transfer on the functioning of
the extremely tightly controlled, integrated and balanced functioning of
all the tens of thousands of structures and processes that make up the
body of any complex organism.
With this view one has to take stock of the basic difference in the
approach of the old biotechnologies versus the new genetic engineering
and the outcome thereof. Understanding the original and the new biotechnologies
gives rise to two different paradigms.
The first one is based on the broad and holistic approach to a specific
agronomic and socio-economic situation while the latter tends to search
for a universal solution down at the molecular level. The fact that the
new biotechnologies have taken off from the original is obvious. In trying
to answer how the new biotechnology could benefit rural poor, a lot of
work needs to be done. Research that is people oriented should strive to
enhance multiple cropping and rotation techniques, rationalization of the
use of wild plants in local diets and the upgrading of traditional crop
protection practices. Using science in general to enhance the sustainable
production systems is more important than offering miracle solutions with
a reductionist approach.
