Select Committee on Environmental Audit Minutes of Evidence


Examination of Witness (Questions 20-39)

29 OCTOBER 2003

RT HON MICHAEL MEACHER MP

  Q20  Gregory Barker: Am I right in thinking that the issue of accurate crop yield measurement was not incorporated into the design of Field Scale Evaluations?

  Mr Meacher: You are correct.

  Q21  Gregory Barker: Why was that?

  Mr Meacher: I do not actually know the answer to that because, as I have indicated, I was not responsible for the structuring of the trials but I can venture an answer, which is that I think SCIMAC were responsible for the design of the trials and that was not something which SCIMAC would have wished to include.

  Q22  Gregory Barker: So do you think, for example, that the failure to have an accurate measurement of sugar content in the GM sugar-beet could be obtained when the crop was harvested prematurely to avoid problems with British Sugar was a major flaw or, for example, how could the consultants assess the quality of the maize crop for making silage based only on height when dry matter and cob brightness are also important elements in the making of silage?

  Mr Meacher: Well, you are raising very significant technical questions which I cannot possibly answer but if you ask is that important, I think it is important. I think before we go down the track of commercialisation of GM crops we need to explore exhaustively the impacts, the potential impacts upon the environment in every aspect and on human health. So I agree that this kind of further research should be done. I am not saying that we should endlessly prepare and research PHDs for someone to carry through. In the end if you are going to take a decision we need to be sensible about this and decide how much information is necessary, but I do not think anyone can say that the range of information in these Farm Scale Evaluation trials, even though they were conducted well and even though the results are very interesting and actually quite surprising, is yet sufficient.

  Q23  Gregory Barker: With the benefit of hindsight are there any particular environmental impacts which you would have wished to put into the criteria in the trials?

  Mr Meacher: I did indicate this earlier and I certainly think that the most important issue which was excluded is this question of yields. You need somehow to devise a test where farmers are seeking to maximise what they would naturally do in a marketplace situation, in other words that they are seeking to maximise the yield, and on that basis we look at what are the environmental impacts because if we had a result where the environmental impacts were pretty minimal or nothing to worry about but the yield was only half of what the farmer thought he might be able to get or would need if he were going to make it a commercial proposition I think that trial is worthless. Until he is getting a commercially reliable result using techniques which he might reasonably adopt to maximise the yield I think the trial is not realistic.

  Q24  Gregory Barker: Were the biotech companies able to have any influence here, for example were they more concerned about the biodiversity implications than the yield at that stage?

  Mr Meacher: In so far as I believe to be the case, that SCIMAC had a major influence over the structuring of the trials, I think almost certainly it was not total or unique. I am sure they discussed it with my officials in the Department at that point and may well have discussed it with the independent research contractors. But I do think that the industry had a major role to play here. It was certainly they who found the farmers, of course, who provided the fields to grow and paid them, I believe, a certain sum to agree to participate. So the industry had a major influence and over the maize trials I do believe that Bayer crop science—and it was that company which was particularly concerned with maize—it had certainly been reported to me that they advised or instructed (whichever word you think appropriate) farmers who were sowing GM maize to have only one spraying by glufosinate ammonium, which we will no doubt talk a little more about later, and of course the effect of only having one spraying is that the weeds then do come up again. If the weeds do come up again that minimises the environmental impacts in terms of biodiversity because there is food for the invertebrates and the other creatures to eat.

  Gregory Barker: Thank you.

  Q25  David Wright: When the scientists and the panel came together to model the structure of the trial clearly they had a view about the number of sites that they were going to use across the UK, the farm sites. It is my understanding that the number of sites which eventually were used was less than those originally planned. Do you think that that has compromised the modelling work in any way, particularly when, as the Chairman said earlier, there were already some breaches in protocol throughout the process?

  Mr Meacher: I think what the Chairman was referring to were not Farm Scale Evaluation trials. I think I am right in saying that.

  Q26  David Wright: But do you think the modelling was breached by the fact that less sites were used than originally envisaged?

  Mr Meacher: Let me start off by saying the number of sites was, I think, 283 for the three crops, something between 90 and 100 for each crop. I do not believe that that has compromised the results. I do not think the number of trial sites is the reason why we should have any doubts about these results. I think they have a wider validity, for the other reasons that I have questioned. I think that is the relevant point. It is true that quite a large number of sites were vandalised, were partially or in some cases completely destroyed. I utterly repudiate that. I think that is absolutely the wrong way. I completely reject that kind of violent action. However, it did—and I can certainly remember discussions in the Department—get near to the point at which it could have affected the results but the argument which was put to me, which I accepted, was that there was still a sufficient number of fields not to interfere with the general validity of the trials and I think that is correct.

  Q27  David Wright: Just to push you on that, to be very clear what you are saying is that you had some advice from scientists in the Department to say that the trials were still valid, that there was not too much breach, if you like, of the original proposals?

  Mr Meacher: Correct. There was not a breach of the validity at all. There was a significant amount of damage done but that was not sufficient to breach the statistical validity of the trials. That was the advice given to me and I have no reason to doubt it.

  Q28  David Wright: Following on from that, during the period of the trials there was a lot of coverage about progress on separation of crops. There was quite a considerable amount of TV. coverage about revising the separation distance between GM and non-GM crops during the trials. Do you think that the distances which were used in the latter part of the exercise protected the interests effectively of organic and GM-free cultivation, particularly taking into account your comments when you were in Saskatchewan recently, I understand, where you said that if you cannot control flows across the Prairies how are you going to do it in small scale farm trials in the UK?

  Mr Meacher: That is my view and you have rightly quoted it. I think there was a very real problem about coexistence, which is the jargon word for what you are referring to, how you can create a framework to prevent cross-contamination mainly by pollen but actually contamination of seed is another source of this as well as contamination of farming equipment. So it is not just pollen but pollen is probably the main one. The problem, of course, is that pollen does have an unfortunate capacity to blow around and on a windy day it can blow a long way and there are plenty of trials and plenty of research which show that it can blow miles. We also know that bees, unfortunately, do not take account of Government diktat and have a tendency occasionally to fly three or five miles and on the way back to forage. So it is a very difficult issue, genuinely. All that I would say is that the separation distances used in the trials were again decided by SCIMAC. Government was really presented with these as being adequate. They varied between 50 and 200 metres and again it is true, as I understand, that something like around 99% of the pollen will probably fall within those separation distances. The problem is that 1% of pollen is still a large number, several thousands or even tens of thousands of pollen, and on a windy day that can still go considerable distances. Now, in Canada, where they introduced commercial GM in 1996, we have a laboratory which we can examine after seven years. I did speak to the members of the Canadian NFU, who were gung-ho for GM in 1996 because they had been told by Monsanto and others that this would increase their yields, it would reduce the use of herbicides and contamination containment could be reasonably easily dealt with. All of those, they told me—and do not take my word for it because you can get evidence from them—were now not believed by their farmers, that yields had actually gone down, that herbicide use was more than the companies had said it was going to be, at least twice spraying and sometimes three times, and that containment was a very real problem, as you have just said, in terms of the Prairies. My argument is that if you have got the Prairies with these colossal open spaces and you cannot protect organic canola or organic oilseed rape then how will you do it in these tiny islands where there are 60 million of us and farms jostling very close?

  Q29  Chairman: With the greatest possible respect, you actually signed off on those separation distances and you agreed to a 1% tolerance rate for cross-pollination and there are people who suggest that a 1% tolerance rate is like agreeing to being 1% pregnant; it is enough!

  Mr Meacher: Well, I do understand that argument. The problem is, if you do not wish to be pregnant that is fairly simple. We know what to do in order to secure that. It is rather more difficult in terms of getting down to 0 or whatever fraction of 1% you choose. My own preference would certainly be 0.1%. That I think is about the level of detectability and I think one part in a thousand would probably be accepted—although this has never been tested, despite my wish for it to be tested—by the British public. I was told, when I did question this, that this was SCIMAC's view, this was what SCIMAC had agreed and, "If, Minister, you wish to challenge that then you will have to introduce regulation." The opportunity of introducing regulation would probably have destroyed a voluntary moratorium and there would have been all the general difficulties of getting agreement across Government. So I agree with you, it is not ideal, it is not satisfactory but in the circumstances it was probably the best that could be secured.

  Chairman: Thank you.

  Q30  David Wright: Was there any other pressure upon you to take that decision or was that a decision you took solely on your own?

  Mr Meacher: There was not any pressure upon me. The arguments were put to me, as I have just explained, "If you don't like 1%, if you think it too high, if you think the separation distances should be greater," my officials will tell you I was constantly arguing for greater separation distances but, as I say, there were two problems. If you do not make it 200 metres what do you make it? If you make it 500 metres it is still the case that some will get beyond 500 metres. If you make it 10 miles that is absurd. Where do you draw the line in between? There is no absolutely authoritative definitive line which you can draw in the messy world out there in agriculture, that is the problem.

  David Wright: Thank you.

  Q31  Paul Flynn: Do you accept that some industry organisations have said that as a result of these demonstrations there is a case for saying that if GM is managed sensitively it could actually turn out to be beneficial for the environment?

  Mr Meacher: I think you may be referring to a quotation that I recall, possibly in the Western Morning News, is it? If that is a quotation, or wherever it comes from, I do find that absolutely extraordinary because the evidence given in the Farm Scale Evaluation trial results seems to me overwhelming and compelling and it is perfectly clear that the balance (at least in the case of oilseed rape and beet) is overwhelmingly that the biodiversity impact of GM is worse, that there is harm. In the case of maize, which we may come on to in a moment, it is arguable. But to suggest that there is benefit to the environment in the case of the other two crops I just think is absurd; it is risible.

  Q32  Paul Flynn: The figures which you quoted about the beet fields where there was 1,707 beetles discovered in the non-GM crop and 1,576, I believe you said, in the other crop, the difference between those two is about 7 or 8%, possibly not significant. The difference between those crops and the maize and rape of course were 50%, there was more than double in the one. Does it not suggest that the differences between the GM and non-GM are far less significant than the differences between the various types of crops?

  Mr Meacher: Yes.

  Q33  Paul Flynn: Is there not an unintended conclusion from this, a very valuable one, that what is important for wildlife and the diversity of wildlife is to vary the crops?

  Mr Meacher: What you have said is perfectly fair and indeed I myself have taken exactly your own point, that the differences between the crops is more significant. Contrary to what anyone had thought before, contrary to what the scientists or anyone expected, the differences between the crops is significantly greater than between GM and non-GM. However, whilst you are right that in the case of beetles, in the case of beet, the differences are relatively marginal, there were other differences between GM and non-GM which I think were in the extreme case 5 to  1, in many cases 1.5 to 2. So I think it is significant. I do not want to overdo it but I think it is significant. I was asked to comment on your quote that if sensitively handled it could actually be beneficial to the environment. That seems to me a perverse interpretation of the results as we have them.

  Q34  Paul Flynn: Were your views on GM a significant factor in your leaving the Government?

  Mr Meacher: That is a rather wider question.

  Q35  Chairman: That is a Newsnight question!

  Mr Meacher: Well, Mr Paxton always keeps the best until last! I think you would have to ask the Prime Minister that since, perhaps not surprisingly, he did not tell me and many people have surmised about that and I have thought about it. I do not know. It is certainly true that my views were outspoken. They were outspoken in Government. There was a period of four years when my views were perfectly clear and perfectly well known to the Prime Minister and everyone else. Why at this point I should have been dropped, as I say, I do not know. GM may well have had something to do with it but I really do not know.

  Q36  Paul Flynn: Could I ask finally, do you think the results of these trials, including the unintended consequences which came up, have wider lessons for us all in the way that we look at the biodiversity in agriculture and using break crops and so on? Do you think there is a valuable lesson to come out of these trials?

  Mr Meacher: I do and I think that if we are looking for a more sustainable agriculture it is not just a simple question of GM or not GM, I think it is a much more varied, diverse kind of agriculture, such as indeed was recommended by the excellent report from the Currie Commission, which Defra is now trying to implement. So I do think there are very much wider results and we should not get absolutely hung up on the question of GM. It is a very important issue but it is not the only issue.

  Q37  Mr Savidge: The GM herbicide tolerant crops in the farm scale trials were measured against crops under conventional herbicide management. Did I understand you to say in response to a question from Colin Challen that you felt that their performance should have been measured also against organic or low intensity herbicide regimes and if so how would you respond to the industry's argument that that would have been inappropriate since it was never the intention to replace organic crops with GM crops?

  Mr Meacher: First of all, you are correct in saying that I did believe there should have been a comparison with organic or low intensity farming, that part of the spectrum of conventional farming. It is the first time I have heard this, what you say is the industry argument, that there was no intention of replacing organic by GM. I agree, that never was the aim, but that is not the point. That is a singularly irrelevant point, it seems to me. One is talking about the introduction of GM on a commercialised basis where it could be grown anywhere and the possibility, which I think is a very strong likelihood, that it would cross-contaminate organic and in effect wipe it out like organic canola has been wiped out in Canada. That seems to me the issue.

  Q38  Sue Doughty: We come on to the issue of the trials of GM maize and the cultivation which included the use of atrazine, which of course as we know is about to be banned. What impact does the use of that herbicide have on that particular trial? Is the trial still valid? What are your views on it?

  Mr Meacher: Well, I think it is invalid. Atrazine was, as you say, used in the Farm Scale Evaluation trials in respect of non-GM maize even though it was already banned in the Netherlands and Germany and it was known that a ban was being considered in France and, as we now know, God moves in mysterious ways his wonders to perform and when the EU banned this throughout the EU a fortnight before these results came out I think that is a remarkable coincidence. But that is exactly what happened. So the fact is that atrazine will not be used in future. It is going to be phased out once the regulation has gone through, within the next eighteen months. It is going to take a bit of time but that is always the case, but it will not be used in this country or in any other country in the EU and therefore a comparison in terms of the biodiversity impacts with non-GM maize using a chemical which will not be used in future clearly, it seems to me, is invalid. If you want to have a valid comparison it must be using a chemical which will actually be used in future and my surmise—and it is no more than that because no one knows and we are all in for a lot of surprises here—is that if you used what presumably must be a less toxic chemical, one which is not going to be banned by the EU, then you would find very similar results in the case of maize to the other two. Glufosinate, which is the chemical weedkiller used in respect of GM maize, is itself a pretty toxic chemical. It is a neuro-toxin, it is a teratogen, which means it can harm embryos, and it is a very powerful chemical. I think if you had a less toxic chemical for non-GM maize than atrazine you would get, as I say, very similar results, namely that in respect of non-GM maize the biodiversity impacts were better. There is a further point which I could make, which I do not think has been made and which I think is important, that Liberty (the brand name given for glufosinate) was used on GM crops throughout the Farm Scale Evaluation trials when it was known, I think, to ACRE and to SCIMAC that Liberty would not be used on its own in any future commercial growing of Chardon LL or any other GM maize varieties because in order to be effective it has been used in the United States in a mix which is Liberty ATZ, ie it involves a significant proportion of atrazine, which I think the manufacturer recommends to be something of the order of 32% but which American research, and I quote Professor Mike Owen of the Iowa State University, who said that the atrazine percentage in the Liberty ATZ mix is probably nearer to 90%. So that also is going to change dramatically in future. So for both of those reasons I think we clearly either have to accept that in the case of maize, as with the other two, we should not proceed—I think there is a logical case for that—or that at the very least there have got to be further trials using chemicals which do not include atrazine. My last point is that it must be a commercial yield trial, not with the industry influencing the number of sprayings which take place. If we had new trials on that basis I think they would be worthwhile doing.

  Q39  Sue Doughty: This leads on to the fact that the Scientific Steering Committee argues that enough of the trials were comparing GM cultivation with traditional herbicide regimes which did not include atrazine so that the overall results are still valid. From what you are saying there are some queries altogether about the maize trials?

  Mr Meacher: As I understand, the large majority of the maize trials did involve the use of atrazine. I accept not all of them, but I equally make the point which I have just made that marketplace situations in the United States where farmers are concerned about yields also involve atrazine heavily involved in a Liberty ATZ mix. So for both sides of the equation I think we need new trials which do not on either side include atrazine.
