Westminster HallWestminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.
Each debate is chaired by an MP from the Panel of Chairs, rather than the Speaker or Deputy Speaker. A Government Minister will give the final speech, and no votes may be called on the debate topic.

I congratulate the hon. Member for Bath (Ben Howlett) and the many petitioners on raising this important subject; I can report that many of my constituents are positively buzzing with excitement at the prospect of this debate.
We all agree that we need bees: they pollinate our food crops and wild flowers and play an essential role in supporting wider biodiversity. As we all know, however, their numbers have declined dramatically. DEFRA described the trend as “severe” and admitted that the sharp decline in England is greater than that experienced by any other country in Europe. We have lost more than 20 species of bees in just over a century, and 35 bee species are considered to be under threat of extinction. This is clearly a very serious issue.
The reasons for the problem are complex and many. They include habitat change, the spread of pests, diseases and invasive species, and climate change. The list goes on, and its breadth is intimidating to lay people. Those multiple pressures and stresses are sometimes linked and interrelated, so our responses must be sophisticated, but there is one contributory cause that could and should be tackled now: the use of pesticides, and in particular of neonicotinoid pesticides.
As we have heard, neonicotinoids have been used widely by farmers in the UK for pest control purposes on a range of agricultural and horticultural crops—in particular, as seed treatments on oilseed rape, cereals, sugar beet and maize. Neonicotinoids act on the brains and nervous systems of insects, including bees, and affect motor function, feeding, learning, homing, foraging and reproduction.
Two years ago, the European Union restricted the use of three types of neonicotinoid pesticide—a move supported by the majority of EU member states, but, ironically, not by the “greenest ever” coalition Government, who were one of just a handful of member states to oppose the measure. That decision flew in the face of hard, sound evidence. Indeed, the European Food Safety Authority concluded that the three commonly used neonicotinoids posed an unacceptable danger and
“A high acute risk to honey bees”.
It recommended a full ban on all neonicotinoids.
My hon. Friend is making a very good case. As he said, it was disappointing that the UK opposed the ban. Does he agree that the scientific evidence gathered since then has strengthened the case in favour of a ban?
I very much agree. Those of us who have ploughed through the detailed report find it overwhelming. It was disappointing that, after opposing the earlier advice, the coalition Government published a 10-year national pollinator strategy for bees and other pollinators that did not go nearly far enough. Specifically, it ignored the challenge that neonicotinoid use poses to pollinators.
This autumn, the Government, despite the growing evidence demonstrating the adverse impact of neonicotinoids on pollinator numbers, granted an emergency authorisation for their use. In my county of Cambridgeshire, it allowed farmers to plant oilseed rape with neonicotinoid-treated seeds, which sparked many protests across my constituency and contributed to half a million people across the country signing petitions.
Does my hon. Friend agree that that decision was made a little too soon, as not enough research had been done?
I thank my hon. Friend for that point. Many people felt that at the time. We all agree that the challenge is how best to take a science-led approach to the use of pesticides. We must balance the need to support farmers and protect food security with the need to protect wildlife and reverse the decline of pollinators.
As a former vice-chair of the all-party group on honey bees, I welcome this debate but I caution my hon. Friend that it is difficult for farmers and those of us who are not scientists. On 26 August, the European Food Safety Agency put out a press release stating that neonicotinoids should continue to be banned, even though it was still gathering evidence on a procedure that did not close until 30 September. It is now considering that evidence and looking at whether the ban should continue. That does not help, and makes the issue more confusing for people.
My hon. Friend makes a very good point. These issues are complex, and we are trying to balance the various risks. The Government said that they will listen to the scientific evidence to inform any changes to their position, but despite the strong evidence they still seem to be sticking their fingers in their ears. Since the EU restrictions were introduced two years ago, many peer-reviewed studies have been carried out in lab and real-world settings that underline how damaging such chemicals are for bees.
I just want to fly in on this debate with the observation that the Environmental Audit Committee published a powerful report in the previous Parliament on this very issue. The new Chair of the Environmental Audit Committee is here—or at least he was. That report is well worth reading.
I thank the hon. Gentleman for that intervention. Bees are the gift that keeps on giving to parliamentarians.
I understand farmers’ concerns. Local farmers have explained to me that they have lost crops when they have not been able to use such pesticides. But taking a wider view, there is no really compelling evidence showing widespread crop failure since restrictions on neonicotinoids were introduced. In fact, the 2014 DEFRA report found that in the immediate aftermath of the banning of neonicotinoid pesticides in 2013, the net yield for rapeseed actually increased by 16%. Furthermore, bees have a crucial role to play in improving crop yields and quality. A decline in pollinators as a consequence of neonicotinoids will paradoxically harm the very crops that farmers are trying to protect, and many farmers appreciate that fact.
Would the hon. Gentleman welcome the countryside stewardship scheme that, ultimately, the Government announced earlier this year? I understand that the scheme, which will amount to £900 million, will be open to people competing for projects, with particular emphasis on bees and pollinators. Extra points will be given to agreements that work to support bees, pollinators and other farm wildlife. Surely that is a really good opportunity for people in the countryside—farmers and others— to bid for projects under the scheme and, hopefully, to produce the evidence we need to keep our bee population healthy.
Stewardship schemes have always been important in rural areas. I strongly support them and, as someone who believes in intervention, I will continue to do so.
New research suggests that neonicotinoids might be damaging food production. There is some evidence that apples pollinated by bumblebees exposed to neonics are of a lower quality to those pollinated by neonic-free bumblebees. Although I sympathise with and understand the concerns of farmers who argue that they need such chemicals to grow their crops, it is worth bearing in mind that, given the rate at which bee colonies are collapsing, before long many existing crops will be at risk unless farmers take the very expensive action of pollinating their crops themselves—a service currently provided free of charge by bees across the country.
The hon. Gentleman is making an excellent speech. Members on both sides of the Chamber would agree that the decline in the bee population in this country is higher than in any other country in western Europe. The hon. Gentleman is contending that the reason for that decline is the use of such pesticides. If that is not correct—I do not know whether it is or not —can he suggest a possible alternative reason, or does every route that he has used to explore this issue lead him to conclude that such pesticides are the cause of the decline in the bee population in this country?
The hon. Gentleman comes to the sensible conclusion—the one that I am coming to—that the use of neonicotinoids is the prime problem that we should be acting against. When all is said and done, pollination services are critical for both ecosystem function and crop production and are estimated to be worth between £430 million and £603 million a year to UK agriculture.
In conclusion, bees have been the unhappy victims of neonicotinoid use. Their decline is not only devastating for wildlife, but damaging to food production and our agricultural economy. It is time that the Government ended what some of us fear might be a slight case of knee-jerk anti-Europeanism, listened to the public pleas and scientific sense and ensured that our bees and farmers can flourish.
