Top cotton researchers ignore adverse impacts of genetic engineering
The World Cotton Research Conference in Athens attracted delegates from
more than 50 countries but papers demonstrated the lamentable lack of investment
in research for ecological farming.
Transgenic cotton is spreading at an
incredible pace. In the US, 45% of cotton planted is now transgenic.
Roundup-resistant cotton covers 1.3 million ha. and Bollgard Bt-cotton,
introduced in 1996, already makes up 1 million ha. In Australia, 20% of cotton
is transgenic this year, mostly Bt-cotton (Ingard). In China, 45,000 ha of
Bt-cotton were planted in 1998. Experimental cultivation is underway in Mexico,
Spain, Greece, Egypt, South Africa, and Argentina. India and Pakistan are also
engaging in transgenic research.
Although Bt cotton was claimed to reduce pesticide use by 60%
this does not necessarily lead to real economic benefits to the grower.
Furthermore, efficacy is reduced over the season and over years and is
geographically variable. It is also certain that insect resistance will build up
to Bt.
The research interests certainly showed a preoccupation with
transgenic cotton and the issues of large-scale irrigated cotton. Yet the papers
on transgenics, primarily on Bt cotton, paid almost no attention to the
ecological implications and failed to consider the dramatic transformation
taking place, with farmers becoming locked into contracts with seed firms.
Some countries are looking to reduce pesticide use through
integrated pest management (IPM) practices. Australian policy is to advocate
pesticide use as a last resort. IPM is the technology of choice, rather than as
pesticide resistance management. But they consider control through natural
enemies is some way off. By contrast, a US keynote speaker focused on management
of pesticide resistance, and ‘tremendous potential for transgenic
varieties’. The US approach still emphasises massive pest eradication
programmes.
Against this background, one of the three papers out of 379
on organic cotton could have been overlooked, and a project in Greece, for
example, showed that while yields dropped substantially in the first 2-3 years,
they surpassed conventional in the fourth year of production eventually giving a
9% higher gross margin to the farmer.
Researchers showed little interest in the problems of
small-scale rainfed cotton, although developing country presenters discussed
appropriate pest management for small scale farmers. In developing countries the
socio-economics and farming systems issues have greater importance. FAO
representative Barbosa stressed that: “Especially in developing countries,
most of the accumulated information developed by research has not been
translated into changes in the way cotton growers control pests and does not
benefit the society which invested in research.”
In an atmosphere notable for the lack of focus on ethical,
socio-economic and ecological effects of transgenic varieties, the President of
the Greek Cotton Board closed the conference with an encouraging request: “an
ethical code should be developed for transgenic research, and decided upon
during the next World Cotton Research Conference.”
World Cotton Research Conference, Athens,
Greece, September 6-12, 1998, abstracts of papers presented are available for
consultation at the Pesticides Trust [now PAN UK].
