GM Foods Can Benefit The Developing Countries
Part of the answer lies in using ecological approaches, such as integrated pest management, that underpin sustainable agriculture. Another key ingredient is the developement of participatory approaches that strenghten farmers' own experimentation and decision-making. But these alone will not be enough.
Biotechnology is going to be an essential partner, if yield ceilings are to be raised, if crops are to be grown without excessive reliance on pesticides, and if farmers on less favoured lands are to be provided with crops that are resistant to drought and salinity, and that can make more efficient use of nitrogen and other nutrients.
Over the past ten years, in addition to support for ecological approaches, the Rockefeller Foundation has funded the training of some 400 Asian, African and Latin American scientists in the techniques of biotechnology. They are now developing new crop varieties suited to local conditions.
Most of the new varieties are the result of tissue and marker-aided selection. One rice, called La Fan Rockefeller, and widely grown around Shanghaï, has boosted yields by up to 25 per cent.
Another, developed at the West African Rice Development Association, is a cross between Asian and African rice species. It combines the best features of both - tolerance of drought and weed suppression - with high yields.
But we are also supporting the production of genetically engineered rices. There are now varieties that can tolerate aluminium toxicity, and others that are capable of withstanding submergence.
Perhaps a greater potential benefit will come from a new rice engineered for beta carotene - the precursor of Vitamin A - in the grain. Two million children die indirectly from Vitamin A deficiency each year. Beta carotene is in the leaves of rice. Getting it into the grain of the rice is where genetic engineering has succeeded where traditional plant breeding has failed. We now need to assess fully these potential benefits and to explore the likely risks to the environment and to human health.
Let me recommend some specific steps that you at Monsanto could take today that would improve acceptance of plant biotechnology in both the developing and industrialised worlds.
First, consumers have a right to choose whether to eat GM foods or not. Monsanto should come out immediately and strongly in favour of labelling.
Third, phase out the use of antibiotic resistance markers. The likelihood of such genes generating antibioic resistance in livestock or humans is small; but alternatives exist and should be used.
Fourth, the big seed companies could agree to use the plant variety protection system in developing countries, rather than the use of patents. This will allow farmers to retain the seed and public plant breeders to continue to innovate.
Sixth, donate a number of useful technologie, for example the agrobacterium transformation system, to the developing countries.
Eighth and finally, we need a new way of talking and reaching decisions. You will not overcome public concern in Africa, Asia and Latin America simply by issuing statements reassuring poor people that you are committed to feeding them and caring for their environment. It would be better to treat them as equal partners in a dialogue.
This is not the time for a new offensive by a PR agency. It is time for a new relationship based on honesty, full disclosure and an uncertain shared future.
