Select Committee on Environmental Audit Written Evidence


APPENDIX 10

Letter to the Clerk of the Committee from Swindon Friends of the Earth

  Members of Swindon Friends of the Earth have observed the following crops grown as part of the farmscale trials:

    three Spring oil seed rape trials, one in Wiltshire (subsequently destroyed by farmer) and two in Oxfordshire;

    three winter oil seed rape at Hinton Waldrist, Oxfordshire; and

    two forage maize trials at Hinton Waldrist, Oxfordshire.

  We draw the Environmental Audit Committee's attention to the Friends of the Earth critique of the farmscale trials that can be accessed at www.foe.co.uk/resource/reports/science_smokescreen.pdf[9] that covers many of the questions posed.

1.  THE ADEQUACY OF THE DESIGN ON THE FARM SCALE TRIALS AND THEIR ABILITY TO ANSWER THE QUESTIONS POSED AT THE OUTSET OF THE TRIALS

  The main failing in the design of the trial was a failure to measure the yield of the crops and to assess how this related to biodiversity.

  Whilst studies have shown that the "weediness" of a crop does not have a major impact on yield losses in the mid to late stages of crop growth, competition from weeds in the early stages of establishment of the crop can have a marked impact with major losses reported. This is particularly the case of crops like maize and beet where much bare tilled land is left between the rows of crop.

  Swindon Friends of the Earth has been criticising the design of the farmscale trials since the protocols were first discussed on the grounds that the crops might not be managed to commercial standards but managed to maximise weed growth in the GM half or minimising it in the conventional crop. In view of the fact that GM crops have not been grown commercially in the UK, it seemed only appropriate to measure comparative yields of the two halves in order to detect bias. In order to appease our concerns, we were lead to assume that a rough estimate of yield would be provided by the farmer. We were assured that National List (NL) trials looked closely at such matters as yield and quality of the relevant crop. However NL trials are performed in weed-free growing conditions whilst GMHT varieties are not grown with the linked herbicide. We were disappointed to learn (page 1816 of the report) that farmers' estimates of yield were gathered where available but in many cases these were not adequate for analysis. The scientists conclude that "it is unlikely that yields were reduced by the timings of GMHT herbicide application used in this study." Nonetheless, we recognise that weed control plays an important part in crop management and this applies to organically produced crops too. Whilst the timing of application of the post-emergence herbicide is one factor, the quantity of active ingredient in the spray is another. There is a balance to be met between an acceptable level of weeds in a crop that, for example, an organic farmer might find acceptable to one where the crop is grown to maximise yield but where wildlife suffers a decline (as in the NL trials).

  As such, if reasonable yields can be achieved in a GMHT crop and management of the cropped area also provides a reasonable habitat for farmland wildlife that reverses the decline in farmland biodiversity (as achieved in organic farming) then this might indicate a positive benefit of growing GMHT varieties. However without access to any data on yield, this important consideration cannot be factored into the equation. It would seem prudent to examine yield data where it has been collected in order to see whether, for example, only favourable yields have been recorded for GMHT maize but where biodiversity assessments were statistically lower than the average—Figure 2b page 1807 clearly indicates maize trials where weed control in the GMHT maize was greater or equal to that achieved in conventionally grown maize.

2.  THE CONDUCT AND OPERATION OF THE TRIALS

Doubts about GMHT maize and other research required

  With regard to GMHT "Liberty Link" maize, the results of the farmscale trials show that conventional maize management, that involved atrazine control of weeds on all but four of the trial sites, was more harmful to wildlife. 100% of commercial fodder maize (excluding organic varieties) fields are sprayed with atrazine but its use on fodder maize is soon to be phased out. It is unusual in farming to have one herbicide that so dominates market use. Whilst other herbicides used on crops may come and go, the role of atrazine in maize management is unprecedented and requires special consideration in this study. Whilst the results from the four maize trial sites (where atrazine alternatives were sprayed) would not be statistically significant, it would be useful to assess and compare the results in order to see if the impact on farmland ecology is the same, worse or better than those treated with atrazine before making any decisions.

  In addition, we assume that data has been collected that compares farmland biodiversity in organically managed maize crops compared to conventionally treated crops. This might give an indication of the potential to grow fodder maize with atrazine alternatives and to assess how this might compare with the results of the farmscale evaluations for maize.

3.  THE WAYS IN WHICH THE RESULTS OF THE FARM SCALE TRIALS WILL BE INTEGRATED WITH POLICY AND DECISION-MAKING

  DETR (now DEFRA) Biotechnology Safety Unit (and the Scottish Executive) produced a report dated August 2000 that was published on their web site on 20 February 2001. The paper was entitled "Farm-Scale Evaluations: Background Papers on the Evaluations—The Science of the Farm-Scale Evaluations". Paragraph 5 states:

    "if GMHT herbicide management does exacerbate the adverse effects of conventional agriculture, the FSE results will provide the evidence needed to modify or delay EU directives covering the commercialisation of GMHT crops until risk associated with the management of these crops has been fully assessed. The FSE are probably one of, if not, the largest ecological investigation of their type in the world and will provide invaluable information about the indirect effects of non-GM conventional farming as well as those of new GM technology."

  The adverse findings related to the management of glyphosate tolerant beet and glufosinate ammonium tolerant spring sown oil seed rape now provide the evidence needed to initiate a ban or restriction on cultivation should the GMOs receive an EU Part C marketing consent.

4.  THE IMPLICATIONS OF THE TRIAL RESULTS FOR GOVERNMENT AND OTHER DECISION-MAKERS; AND

  On a case-by-case basis, we suggest that there are now grounds to impose Article 23 of the deliberate release of GMOs DIRECTIVE 2001/18/EC on GMHT beet and spring-sown oil seed rape should a Part C consent be provided.

  This safeguard clause states: "Where a Member State, as a result of new or additional information made available since the date of the consent and affecting the environmental risk assessment or reassessment of existing information on the basis of new or additional scientific knowledge, has detailed grounds for considering that a GMO as or in a product which has been properly notified and has received written consent under this Directive constitutes a risk to human health or the environment, that Member State may provisionally restrict or prohibit the use and/or sale of that GMO as or in a product on its territory."

  Moreover the UK government should submit the results of the farmscale trials to inform EU Member States in the decision making process to market these GMOs.

5.  THE COSTS AND BENEFITS OF GM FOOD, BEARING IN MIND THE POTENTIAL MARKET, IN THE LIGHT OF THE FARM SCALE TRIALS AND THE RECENT STRATEGY UNIT REPORT

  We are informed (GM Nation? The Public Debate booklet on GM crops/food in section on Environmental Impact, Q.4 "What about UK science ?":  views "for") that biotechnology companies employ almost 20,000 people in the UK, and contribute approximately £2 billion to the British economy" We are told (same reference) that not allowing commercial growing of GM crops will force GM companies abroad. This is echoed in the Strategy Unit report ("There would be a significant opportunity cost if the UK lost its ability to research, develop and bring GM crops to market.")

  What we are not told is that there are only 1,145 people employed in the UK agricultural biotech sector (DTI figures*). This figure presumably includes people working outside transgenic biotechnology such as those working in marker assisted breeding or radiation induced mutation techniques. There may well be another 19,000 people working in biotechnology such as medical applications.
