Scientific rabble drowns out debate on GM crops

London’s Science Museum, with support from the Consultative Group on International Agricultural Research (CGIAR), has staged an exhibit to debate GM crops. Last night saw the actual debate. Our man in the hazchem suit reports:

“Future foods: join the GM debate.” The cry rang out from London’s Science Museum as it worked hard to assemble a public meeting (on 22 January 2009) to debate the issues raised in its temporary exhibition of the same name.

Despite fears from some observers that this debate and the accompanying exhibition were to be used to grace GM technology with phony public endorsement, in reality it all turned out rather different. Whether you were pro, anti or agnostic on the issue of GM farming and food, there was little appetite from the panel of speakers, let alone from most contributors from the floor, for the wholesale adoption of GM crops.

Defra (the UK’s Department for Environment, Food and Rural Affairs) chief scientific adviser Bob Watson stole the show with his blunt analysis of the real food and nutrition problems facing the world. The goal, he said, has to be how to feed 900 million hungry people in the developing world.

This is not a challenge for technology to solve alone; we need a pro-poor trade regime, we need real rural development; we must put farmers at the centre of the debate and pay them for global public goods as well as food production, said Bob Watson. ((This sounds faintly like a call to allow agrobiodiversity to do more than simply supply genes, but I could be biassed. Ed.))

“We may need GM in the future, but at present it is an oversold technique, which needs examination on a case by case basis,” he concluded.

Professor Tim Lang, Professor of Food Policy at City University, was equally lukewarm about the prospects for GM crops to solve what he termed the new fundamentals of farming and food production. Any solution has to operate under and — even better — help to solve the global pressures on energy supply, soil quality, water availability, the carbon cycle. To Professor Lang the key GM policy and political issue is ownership of the technology and its control.

As the debate opened up to comment and questions from the floor it soon became apparent that the organisers — who had feared hectoring, unruly behaviour from an anti-GM “rabble” — were in fact faced with irate researchers from such bodies as the John Innes Institute. Their degree of upset that society might wish to have a say on the direction that science is leading them was illuminating.

One such contributor asked why all the speakers were treating GM as a “generic science” with generic risk when each application was different and, in any case, merely mimicked “natural” processes. (All the speakers had carefully talked of “case by case” analysis.)

Bob Watson’s reasoned answer was lost in a cacophony of interruption from other researchers, forcing him to describe their approach as rude and uncivilised. An early retreat to drinks and an interval in debate was hurriedly called before the honour of the scientific establishment could be tarnished further.

Perhaps they do debate differently in Norwich?

Rice thrice

Our chums at the International Rice Research Institute have been busy, with no fewer than three press releases in two days.

First up, US$11 million over three years from the Bill and Melinda Gates Foundation to re-engineer rice’s photosynthetic pathway. For the record, there are two different pathways, known as C3 and C4. ((Read all about it in Eating the Sun.)) Rice is C3. C4 is more efficient. So, hey, let’s make rice C4. The release says that as a result of this grant “rice plants that can produce 50% more grain using less fertilizer and less water are a step closer to reality”. But it doesn’t say how many more steps there might be. And if C4 rice is such a good idea, you might wonder why Nature, consumate tinkerer that she is, hasn’t already made it. ((see Denison, Kiers and West for some clues.))

Then there’s another US$30 million over three years (from Bill and Melinda and USAID) to create The Cereal Systems Initiative for South Asia (CSISA).

Major objectives of CSISA include better crop management and postharvest technologies and practices; the development and dissemination of improved rice, wheat and maize varieties; and the creation of a new generation of agricultural scientists and professional agronomists. The initiative will focus initially on eight hubs in Bangladesh, India, Pakistan, and Nepal, which represent key intensive cereal production systems that play a major role in feeding close to a quarter of the world’s population. …

CSISA’s 10-year goal is for four million farmers to achieve a yield increase of at least 0.5 tons per hectare on five million hectares, and an additional two million farmers to achieve a yield increase of at least 1.0 ton per hectare on 2.5 million hectares.

That deserves to be a success, and I don’t think it depends on C4 rice.

And finally, to implement those two programmes, and STRASA (Stress-tolerant rice for poor farmers in Africa and South Asia), another one supported by the Bill and Melinda Gates Foundation, IRRI signed a new three-year agreement with the Indian Council of Agricultural Research (ICAR).
