Pollinators and Pesticides

David Heath Excerpts

Thursday 6th June 2013 Commons Chamber

[Joan Walley]

I welcome my hon. Friend’s intervention. Our report clearly states that there is no one solution and that we need, as he rightly says, a whole new systemic approach. The core of our report is that we need to get the balance right between scientific evidence and the precautionary principle, but there are very many issues that relate to all this.

We have had further support from many members of the general public and concerned interest groups, not least Bedfordshire Beekeepers Association, which said:

“Your work has been an inspirational example of democratic scrutiny in action…we hope that you will be able to hold government to account and influence policy making both at national and EU level.”

This is exactly what we are doing today and intend to continue doing. This debate is by no means our only follow-up to the report. We are raising the issue today to see how the many things that need to be done can get done, with the direction of the Government.

The Committee decided to conduct our inquiry because the available evidence indicated that insect pollinators have experienced serious population declines in the UK in recent years. For example, we heard—this is quite shocking—that two thirds to three quarters of insect pollinator species are declining in the UK. Indeed, the 2013 report “State of Nature” assessed 178 bee species in the UK and found that half were in decline. For the benefit of the House, I should explain that insect pollinators include not only honey bees and wild bees but other insects such as hoverflies, moths and butterflies. At the moment, the honey bee is the sentinel species for all insect pollinators, which means that most scientific studies involve bees, but given the biological differences between the various insect pollinators, it is vital that the Government monitor a wider range of species. I hope that this is an uncontroversial point on which the Government will agree with my Committee.

[The Minister of State, Department for Environment, Food and Rural Affairs (Mr David Heath)]

indicated assent.

[Joan Walley]

I am very pleased to see the Minister nodding. I refer him to our recommendation 13: “Defra must”—I stress “must”—

“introduce a national monitoring programme to generate and monitor population data on a broad range of wild insect pollinator species to inform policy making.”

We felt that that is the bottom line and the starting point of what now needs to be done. As we went through our deliberations and came to reach our decisions, we endeavoured to find as much common ground among members of the Committee as we could before we turned to the issue of neonicotinoids.

Let me move on to the question of why insect populations might be declining. I want to make it clear at the outset that the health of insect pollinators is defined by a range of factors, including not only pesticides but urbanisation, loss of habitat, agricultural intensification and climate change; obviously, weather patterns affect things as well.

I am grateful to the hon. Lady for raising that point about commercial confidentiality and the lack of transparency. We hear a lot at the moment about lobbying and related issues, but if the agri-chemical industry wishes to make claims about the value of its products, it must open up the evidence to full scrutiny. There is no case for hiding behind so-called “commercial confidentiality”. That prevents the open, transparent and informed policy making that is so badly needed. I agree with the hon. Lady and her point relates to one of the recommendations in our report.

When the weight of peer-reviewed evidence rendered untenable DEFRA’s position on the need for unequivocal evidence, it claimed that it would commission the Food and Environment Research Agency to conduct a realistic field study to resolve the matter. That study was not peer reviewed and it was, as one witness to our inquiry presciently pointed out, clearly too small to provide conclusive results. It was undermined by fundamental errors in its execution, such as placing the various hives that were used in the experiments outside on different days of the year.

Our view on the study, which was that we should not accept it, was confirmed by the European Food Safety Authority on Tuesday, when it identified the same weaknesses as we did.

[Mr Heath]

indicated assent.

[Joan Walley]

I am glad to see the Minister nodding his head. The conclusion was that there was no reason for EFSA to change its view.

DEFRA told us that its pesticides policy was underpinned by the precautionary principle. I fear that in this case, that statement of intent has not been matched by DEFRA’s actions. Interestingly, the private sector appears to be more willing than DEFRA to implement precautions. In the course of our inquiry, we heard that major do-it-yourself chains such as B&Q, Wickes and Homebase were withdrawing neonicotinoids from sale for domestic use, and supermarket chains such as the Co-operative have prohibited their suppliers from using neonicotinoids in anything other than exceptional circumstances. I also welcome the press release from Waitrose, which states that it is looking to do the same in respect of flowering crops.

As our report was taking shape and we were having involved discussions among ourselves, we had to extend the length of our inquiry to take account of developments elsewhere, because it was clear that we were being overtaken by events such as the European Commission’s regulatory action. Although the growing weight of published scientific research did not impress DEFRA, it led the EC to take action. The EC is responsible for licensing chemicals for use in European agriculture. It instructed EFSA to draw up new risk assessments for neonicotinoids in relation to bees. The revised risk assessments led the EC to propose measured regulatory action, with a two-year EU-wide moratorium on the use of three of the five neonicotinoids on crops that are attractive to bees.

The EC proposal was put to a qualified majority vote on 15 March. As we all know, the vote was inconclusive and the UK abstained. The hung outcome of the vote allowed the EC to implement the appeal procedure, which led to a second vote on 29 April. I understand that between 15 March and 29 April, there was intensive lobbying and negotiation in Europe. Indeed, I went out personally to present our report to the European Commissioner. Finally, the EC amended its initial proposal. It recognised the need to delay the introduction of a moratorium to allow the seed supply chain time to adjust, which was a recommendation of our report. That is an example of how my Committee focused on the practical outcomes for the agricultural sector. We did not want to make any knee-jerk recommendations and we wanted there to be time for the matter to be properly understood and acted on.

In the second vote, on 29 April, the UK shifted from abstention to active resistance by voting against the proposed moratorium, despite the concessions made by the European Commission. However, countries such as Germany, France, Spain and the Netherlands all voted for the moratorium, which will consequently be introduced across the EU on 1 December 2013.

What effects will the two-year moratorium have on UK agriculture? First, I want to highlight that when neonicotinoids were banned for use on maize in Italy, there was no negative effect on yield. Secondly, the moratorium will prevent farmers from using neonicotinoids on

“crops that are attractive to bees”,

which of course excludes sugar beet, crops grown in glass houses and winter wheat; it is quite a proportionate measure. Thirdly, neonicotinoids are a relatively recent innovation. Oilseed rape, for example, was a viable UK crop before the introduction of neonicotinoids in the mid-‘90s.

Some have argued that a moratorium on neonicotinoids will lead farmers to spray greater quantities of other more environmentally harmful pesticides, such as organophosphates and pyrethroids. However, it is open to DEFRA to ensure that that is not the case. It is clearly in the interests of the environment, food security, minimising resistance among pests and maximising agricultural incomes that the least possible amount of pesticides is used in agricultural production. Indeed, in talks I have had with different bodies they have said that such a moratorium will mean that there must be a focus on what to do and what alternative proposals to come up with, so that we incentivise a more healthy approach to crops.

To that end, integrated pest management is a broad approach to plant protection that minimises pesticide use and encourages natural pest control mechanisms. By 1 January 2014, all pesticide users will be required to adopt IPM under the European directive on the sustainable use of pesticides. If UK farmers practise IPM, the argument that a moratorium on neonicotinoids will lead to unfavourable environmental outcomes does not hold. I believe that was very much a deciding factor in the Committee’s reaching its unanimous decision.

DEFRA does not appear to have prioritised compliance with the directive on the sustainable use of pesticides. The directive states:

“Member states should adopt…quantitative objectives, targets, measures and timetables to reduce…the impact of pesticide use on the environment.”

However, a DEFRA official dismissed such targets as “meaningless”, which sits uneasily with the Department’s stated commitments to integrated pest management. Indeed, our report was halted or delayed because the Government were slow to make a full response to that European directive.

Other than the recommendations on the moratorium of certain neonicotinoids, the importance of monitoring the health of pollinators and the introduction of integrated pest management, many other detailed issues arise from the Committee’s report that relate to risk assessment and risk management. Those include reforms involving the European food safety authority, where our Government, should they wish to, could take the lead, CAP reform and recognising the importance of less secrecy and greater transparency in the risk assessment trials undertaken by the agrochemical industry—the point raised by the hon. Member for Totnes (Dr Wollaston). I am disappointed that the Government have chosen to delay their response to our report, which was due this week, but I look forward to their detailed response on the work we have carried out. For now, however, events have moved quickly and DEFRA did not take our advice when the issue was raised by the European Commission.

In conclusion, I have three questions for the Minister. First, I believe DEFRA has said it will commission further field research on neonicotinoids and bees. Will that research be published in a journal and be peer reviewed? Will the Minister consider commissioning the British scientists who participated in the Gill and Whitehorn studies, rather than FERA, whose previous report was discredited? Is it DEFRA policy to reject all laboratory studies—and, by extension, scientific method—as a basis for action? Secondly, how will DEFRA ensure the effective implementation of the sustainable use of pesticide directive? Thirdly, will the Minister explain what changed between the first EU vote on 15 March, when the UK abstained, to the second EU vote, on 29 April, when the UK voted against a moratorium?

The UK public are concerned about bees and pollinators. When I raised this at Prime Minister’s Question Time, he stressed the importance of the precautionary principle. As we look forward to the summer, people’s minds will be on gardening and planting, and farmers’ minds will be on planting and harvesting. It is critical that we hear from the Government on how they will respond to the EU moratorium.

[Mr Tom Harris (Glasgow South) (Lab)]

I begin by echoing other Members’ tributes to my hon. Friend the Member for Stoke-on-Trent North (Joan Walley) for initiating the debate. Her Committee has published an important and powerful report on the subject and I commend all members of the Environmental Audit Committee for producing it. I am sure the Minister has pored over the document in detail and will give us his thoughts on it later this afternoon.

Outstanding contributions have been made by my hon. Friend the Member for Gower (Martin Caton), the hon. Member for Stroud (Neil Carmichael) and my hon. Friends the Members for Southampton, Test (Dr Whitehead), for Bristol East (Kerry McCarthy) and for Llanelli (Nia Griffith). As usually happens when Front Benchers wind up these debates, we tend to be left with only the task of repeating many of the points that have already been made. It reminds me of the old saying that at any meeting everything that has to be said has already been said, but not everyone has said it yet. So I shall plough on regardless.

The debate around neonicotinoids has brought the decline of bee and pollinator populations into sharp focus. The profound effects this will have on the future of horticulture, agriculture and the wider environment cannot be overstated. Bees and other pollinating insects play a vital role in our food supply, providing essential pollination services estimated to be worth £440 million to UK agriculture each year, as well as enriching our natural environment and biodiversity.

Two months ago, in April, I convened what I ambitiously entitled a bee health summit, which was attended by leading academics, environmental groups, biotechnology companies, farming unions and representatives from leading apiary organisations. I apologise to the Minister for forgetting to invite him. I am sure his contributions would have been worth while. Predictably, there was a lack of agreement on the topical issue of a ban or moratorium on neonicotinoids, and the evidential base was hotly contested. It is clear that pesticides currently play an essential part in achieving high levels of crop production in the UK and elsewhere, providing affordable food for consumers and contributing to our food security. Getting the right balance between the benefits of natural pollination services and the benefits of pesticides to crop production is crucial.

At the summit, there were passionate calls to support the use of the precautionary principle, which have been echoed in the debate today, to protect against further decline while additional evidence is gathered and analysed. These calls were countered by some bee health experts, bee organisations and, yes, the companies that produce neonicotinoids, which took a more cautious line based on the lack of any assessment of the impact of a ban on farmers’ use of alternative pesticide products and the impact on UK food production and food security.

Such divides are not reserved to the UK, and a split in opinion was also observed at an EU level. However, now that the Commission has approved an EU-wide moratorium on the three types of neonicotinoids beginning in December 2013, it is vital that the Government work with all parties concerned to ensure that any negative, unintended consequences on bee health—for example, the hon. Member for Stroud referred to the wider use of spray insecticides—do not materialise.

What plans do the Government have in place to support farmers in the build-up to and during the moratorium? Does the Minister agree that the moratorium provides an excellent opportunity to help farmers and growers to adopt integrated pest management and reduce the use of pesticides in line with the Government’s own pesticides action plan? Does the Minister agree with the Society of Biology, which has pushed for adequate and stable investment in agricultural research and environmental monitoring, in order to avoid periodic crises where sufficient evidence has not been available for necessary policy decisions? Will he outline how the Government will take advantage of the breathing space afforded by the moratorium to bridge the current gaps in scientific knowledge on the effects that neonicotinoids have on bees and other pollinators?

It is crucial that a monitoring programme is put in place to assess the full impact of a moratorium and the effect that it will have on wild and managed bees and on farmers and their crops. Will the Minister assure the House that an effective monitoring programme will be put in place? I am sure that he, like me, is aware of significant concerns raised in the scientific community that two years will not be sufficient to monitor the effect on bee health of a moratorium on neonicotinoids, not least because of the multiple variables in the natural and farmed environments.

[Mr Heath]

indicated assent.

[The Minister of State, Department for Environment, Food and Rural Affairs (Mr David Heath)]

This has been an extremely good debate and I thank the hon. Member for Stoke-on-Trent North (Joan Walley) and her Committee for their report. She knows that we have had a short delay in responding to her, for the precise reasons that she had a short delay in producing the report. The circumstances have been changing quickly and we want to get it right, so I apologise to her and her Committee for that. My noble friend Lord de Mauley is responsible for this area, but the hon. Lady will appreciate that it falls to me to respond to the debate in this House.

I also thank the hon. Member for Glasgow South (Mr Harris) for his balanced remarks, which showed that this is a complex issue. I am interested in it, not least because as Minister for agriculture I know that bees and pollinators are crucial. I cannot underline sufficiently how important pollinators are to agriculture and horticulture, so of course I have that interest.

I also have an enormous personal interest in the issue. I spoke from the Opposition Benches about bees for a very long time. I spoke on the subject right back in June 1998, when I said:

“We need a step change in investment in the investigation of bee disease if we are to stem a worldwide phenomenon that is lapping at our doorstep and has the potential to become a crisis, both for the insect population and in economic terms”.—[Official Report, 17 June 2008; Vol. 477, c. 204WH.]

That is what I said in 1998, so people are now free to quote that back at me, but I meant it. We were arguing then in the context of very little work at Government level on bees. It took the best part of a decade before we pressed the previous Government to start taking the issue of bees and pollinators seriously, which they did: we now have the national bee unit and I think we now need to go one step further in our approach.

I welcome the opportunity to highlight what the Government have been doing in relation both to pollinators and pesticides and to our future plans. We take this issue extremely seriously. It is crucial. Contrary to what some have said, specifically in relation to neonicotinoid insecticides, we have kept the evidence under close and open-minded scrutiny and we continue to do so. We will restrict the use of insecticides. Obviously, neonicotinoids are now dealt with under the moratorium, but we will deal with others as well, if the evidence shows that there is a need to do so. I will come back to that point later.

The hon. Members for Stroud (Neil Carmichael) and for Glasgow South pointed out that pollinators face many other challenges. It is critical that one issue, such as the use of particular pesticides, does not dominate the debate, because so many other individual factors, when taken together, have a complex effect on our pollinator population.

[Joan Walley]

The Minister has said that the Government will take action if the evidence shows that they need to. Will he explain how that relates to the moratorium delivered by the European Commission?

[Mr Heath]

I will come back to the specific issue of neonicotinoids in a moment. The moratorium is in place, so we will, of course, fully comply with it. We do not not comply with decisions of that kind. I will return to the evidence, because it is a critical issue.

I repeat that bees are essential to the health of our natural environment and the prosperity of our farming industry. The “Biodiversity 2020” document has been mentioned. We have set ourselves the challenge of achieving an overall improvement in the status of our wildlife and preventing further human induced extinctions of known threatened species. We have put a landscape scale approach to biodiversity conservation at the heart of “Biodiversity 2020”. It is vital that that approach is effective in helping to conserve our most threatened species.

Nature improvement areas are beginning to make a difference for species on the ground. The 12 Government-funded NIAs are by no means the sum total of our ambitions. We want to see that approach rolled out more widely by enthusiasts across the country. The hon. Member for Bristol East (Kerry McCarthy) is seeing exactly that in her city. We want that to be extended and it is clearly already happening.

We want to make environmental stewardship more effective. As the House knows, we are in the process of negotiating CAP reform. It is not clear what the outcomes will be. We do not know the extent to which greening measures will be in pillar 1 or pillar 2, or the exact recipe that will emerge from our decisions on agri-environmental schemes that derive from pillar 2 or voluntary modulation. This matter is a key consideration in that context and I will certainly be pressing for it in the outcome.

[Nia Griffith]

The European Scrutiny Committee has requested a debate on CAP reform. Will the Minister say when that is likely to be scheduled?

[Mr Heath]

I am responsible for a large number of things in my Department, but the scheduling of House business is not one of them. In my previous post, I might have been able to give the hon. Lady an answer, but in my current post I cannot. To be honest, now would not be the best time to have that debate because we are just reaching what we hope will be a conclusive meeting of the Council of Ministers. After that, we will have a much clearer idea of the outcomes and how they will be effected in the UK.

We recognise that there is still a need for targeted conservation action for our most threatened species. Natural England’s species recovery programme is designed to help with projects to support priority species, such as the short-haired bumblebee. Many Members have made the point that we are talking not just about the honey bee, but about many other native bee species and other non-bee pollinators. My noble Friend Lord de Mauley has announced that he is considering the development of a more holistic health strategy to cover all pollinators. He has been meeting interested parties, such as Friends of the Earth, to explore what added value that approach could bring.

We will continue with our wider work to understand and counter the various factors that harm bees and other pollinators. DEFRA’s chief scientific adviser and Ministers have met a number of interested parties to discuss that work, including non-governmental organisations. We will seek to host discussions with other stakeholders over the summer.

As I have said, there are many things that we do not yet understand about the reductions in pollinator populations. There are many major factors, including the varroa mite, which was mentioned by the hon. Member for Stroud (Neil Carmichael), foulbrood and the undoubted effects of climate change and environmental and ecological changes in this country. That is why some experts are very unclear as to the quantifiable effect of pesticides. The British Beekeepers Association keeps an open mind on that, as do we. We want to know what the connections are and to see the evidence.

Let us return to the issue of pesticides. As we heard in the debate, the European Commission recently adopted a ban on the use of three neonicotinoids on crops that are “attractive to bees” and on some cereal crops. The ban also covers amateur use, so the Government do not need to bring in an extension.

It is documented that we did not support action, the reason being that we had urged the Commission to complete a full assessment of the available scientific evidence, taking into account new field research that we had carried out. Let us talk about that because it is a serious issue. The hon. Member for Stoke-on-Trent North asked whether we reject laboratory evidence, but of course we do not; it is extraordinarily important. However, we would like some coherence between what we see in the laboratory and what we see in field trials. That does not make field trials the only thing that matter, but such a correlation is not presently there.

From laboratory tests we are clear that neonicotinoids have a toxicity for bees. We do not know, however, what the exposure is in a natural environment, and the two things go together. Many things are toxic but do not create a deleterious effect in the field simply because the exposure is too low. That is where we must do a lot more work, and that is exactly where we are commissioning it. We were clear that the work done by FERA was by no means a satisfactory field trial. We never pretended that it was; it had to be done quickly to meet a timetable—set not by us, but by others—to give at least some indication of whether that correlation was there. Incidentally, I will not accept criticism of FERA scientists on that basis. They are extremely good and do their work in a totally dispassionate and independent way on the best scientific principles. They were asked to do a quick piece of work—which they did—and that is why it was not peer reviewed, as would be normal practice. We felt it was important to put the matter in the hands of the Commission, which was about to make a decision on a highly contentious subject.

I make no apologies for recognising that there is, of course, a strong imperative to look at evidence that suggests a toxic consequence and, where possible, to take a precautionary approach to these matters. However, a precautionary approach is not as two-dimensional as sometimes suggested and must take into account the consequences of the action in question. The hon. Member for Glasgow South mentioned the economic consequences, and of course that is a factor, although not an overriding one.

Of far more concern is a point also raised by hon. Members about alternative pesticides that are fully legal under EU law and that it would be perfectly proper for people to use, such as pyrethroids, organophosphates or carbamates, because the potential is that they would be even more damaging to the pollinator population. That concern does not mean that we should not take action against neonicotinoids if the evidence is clear that they are causing problems in field conditions, but it was not unreasonable to say that the paucity of field-trial evidence was astonishing.

I do not have portfolio responsibility for this matter, but when I looked at it with a view sympathetic to what the hon. Member for Stoke-on-Trent North was saying, I was amazed at how little evidence there was in field conditions, which I think exposes a failure of the scientific world to address the problem. I hope that we can play our part in persuading others across the European Union to take a more rational view of where we concentrate our research so that we get the evidence we need, and that is what we are trying to do. Although our assessment is that the risk to the bee population from neonicotinoids, as currently used, is low, we may be wrong and evidence may come forward from trials that shows otherwise. If such evidence is there, we shall, of course, accept it, but we need more complete evidence than we currently have.

The European Commission has committed itself to a review of evidence by 2015, which we want to be founded firmly on a strengthened scientific evidence base. We will play our part in that and are currently talking about the design of field trials that might be in place during the moratorium period, so that we can gather evidence, not just on the honey bee, but on other bee species as well. The FERA research was on the bumblebee rather than the honey bee. It is important that we understand how other species are affected.

[Andrew Stunell (Hazel Grove) (LD)]

I take a great deal of pleasure in knowing how much my hon. Friend knows about the subject and how sincerely he takes it to heart, but does he understand that some of my constituents see the careful words he has just spoken as indicating that the Government are ducking and weaving? May I ask him, in the nicest possible way, whether the Government will be in a position to take a decision when the further research is done or whether they will want still more research to be that little bit more certain?

[Mr Heath]

Let me be very clear—I am not the world’s greatest scientist, although I have a scientific degree—that we cannot have scientific certainty; we can have only a balance of probabilities based on evidence. We think that the evidential basis for the decision is weak because we do not have evidence from field trials. If the evidence suggests that laboratory results are replicated in field conditions, we will want to take a decision, because we want to protect our pollinator populations. That is important.

I have very little time left because the hon. Member for Stoke-on-Trent North needs to respond to the debate. She asked three questions, including one on the precautionary principle. I hope I have explained our approach on that. She asked about the research and the difference between laboratory and field studies, and about the EU directive on the sustainable use of pesticides, which I believe the Government will implement in full. More work needs to be done on pesticides across the board. It is a misrepresentation to say that the wicked seed companies are pulling the wool over the eyes of the rest of the world. We need transparency of evidence so we know exactly what is happening during the regulatory process and beyond. We are speaking to those companies to ensure that they provide the greatest possible transparency.

The hon. Lady asked what changed between the abstention and the decision to vote no. The answer is that we pressed and pressed again on the need to commission the evidence that we believe would have given a sound basis for the decision, but we did not secure agreement. That is why we are in the position we are in.

The Government are determined to do everything we can to protect our bees and pollinators. They are essential not only to our economy, but to our environment and our ecology. We will take all necessary steps to do so.
