Insect Population

Anna McMorrin Excerpts

Wednesday 20th March 2019 Westminster Hall

[Alex Sobel]

It is always good to have an intervention about beasties. I absolutely agree with the hon. Gentleman. That harks back to my point about abundance and variety. We cannot protect only the bees, because they will not survive on their own without the abundance and variety of insects.

If we projected existing trends downwards, we would end up solving problems caused by the loss of natural systems one by one, which would be a much less efficient way to solve the problems of ecosystems than treating the root cause of the problems. If we look at the trends over the past 30 years, we see that that means not solving the problems but exacerbating them. The most shocking evidence that the Environmental Audit Committee heard came from Matt Shardlow, who said:

“In Germany, what they are looking at is nature reserves and a long-term decline, a 76% decline in the abundance of flying things on those nature reserves”.

Let that just sink in—a 76% decline in flying insects in nature reserves, not urban environments.

There is so much that English research does not yet know, but researchers looking at the swallowtail butterfly—again, this is the work of Professor Hill—found that as fenland habitats decreased in size, slowly the swallowtail became extinct, but before it became extinct it shrunk in size, because there was no point in it flying away from where it was as it would die anyway, because of urban encroachment. Our habitats are becoming fragile and we need to reverse that trend.

The UK does not have the sort of resilience that is needed to assist insects in weathering the storm of climate change. In a global assessment, the UK came 189th out of 218 countries for “biodiversity intactness”.

I thank my hon. Friend for securing this absolutely essential debate. As a fellow member of the Environmental Audit Committee, does he agree that the reduction of insect numbers is especially worrying for the economy, that the impact on the economy will lead to a lack of wild pollinators, and that there will be a knock-on effect from that?

[Alex Sobel]

If we need to intervene and if we have to replace the natural pollinators with artificial pollinators, there will be a huge cost to the economy.

Technology certainly has a place and we need more resilient crops, so we need to move away from the use of chemicals and actually breed that resilience into the crops, which is where technology and research come in. I think there would be a race to the bottom if we said that we could produce enough food only if we increased the chemicalisation of farming.

I will now move on to my recommendations for the Minister—I am sure that she is waiting with bated breath to hear my ideas on how to improve insect populations. I have to say that the Government have belatedly acknowledged the issue and taken some action. I commend the Minister for the following four actions—I am sure that she will be pleased to hear me say that. The Government are developing a national B-Lines pollinator network to reconnect wildlife and they have announced £60,000 of funding for England. They have also introduced a national pollinator monitoring scheme and are moving towards paying land managers for providing public goods, such as biodiversity and pollination services. They are also banning three bee-harming and water-polluting insecticides.

However, the forthcoming environment Bill and the remaining stages of the Agriculture Bill provide unparalleled opportunities to start taking action on preventing the insect Armageddon. Today, as the hon. Member for Richmond Park (Zac Goldsmith) mentioned, the Minister could commit to accepting new clause 11, tabled by the hon. Member for Brighton, Pavilion (Caroline Lucas), which would reduce pesticide use. The Agriculture Bill also provides an opportunity for farmers to be incentivised to deliver nature-friendly farming that will increase insect and wildlife populations, such as providing food for farmland birds and planting wildflower margins. These incentives should be delivered as part of the “public money for public goods” section of the Bill.

The Environmental Audit Committee is still undertaking pre-legislative scrutiny of the draft environment Bill, but it would be fair to say that the proposals for the new watchdog are weak. There must be a higher level of independence for the new watchdog and stronger powers, including the ability to impose heavy fines. We need to enshrine environmental principles in UK law, to make sure that when we make new laws we consider the impact they will have on nature. The Bill should set in stone ambitious and measurable targets for nature’s recovery, which are not just laid out in plans but enshrined in law.

[Anna McMorrin]

Does my hon. Friend agree that to stop this reduction in insect numbers and stop the loss of wild pollinators, which is so important, we need to make use of EU funding streams, and that a bad-deal or no-deal Brexit, which we are at risk of, could have a huge impact on this issue, affecting the future for insects?

[Alex Sobel]

My hon. Friend is absolutely right that there is no guarantee that the EU funding will be replaced, particularly as we have this current uncertainty, and the best deal with the EU is the one that we currently have, which is a point I know she agrees with.

[Alex Sobel]

As my hon. Friend knows, I am a great supporter of the new northern forest. We need to commend the work of the Woodland Trust, and the work of wildlife trusts and other organisations that are protecting our natural ecosystems.

I will talk briefly about climate more generally. As well as an insect Armageddon, we have a climate emergency, although the Government have not yet acknowledged that. Government decisions on spending and taxation would be exempted from environmental principles, while Ministers are required only to “have regard” to them elsewhere. Legally binding, time-bound targets are also missing from the draft legislation. Our future is tied to the future of the planet and economic policies are not independent of the future survival of life on the planet. The environment Bill must acknowledge and enshrine that, and I hope to see that happen in Committee.

There is also more detailed work that the Government could lead to support insect life. They could establish statutory nature recovery network maps with local authority sign-off, which would support the B-Lines network that they have already announced; introduce legally binding targets for biodiversity recovery, including, as separate measures, targets for pollinators and freshwater invertebrate life; design new agri-environment schemes that would deliver safe pollinator habitats and a national network of flower-rich habitats; legislate to reduce the pollution of water courses with insecticides, flea treatments and pharmaceuticals that are toxic for insects; improve the protection of rare and endangered species in the planning system; introduce measures to reduce light pollution; find ways of directing significant new funds, for instance through the environment Bill, to save biodiversity, such as reinstating the aggregates levy sustainability fund, or introducing payments for ecosystem services, which should be a central feature of thinking by the Treasury and the Department for Environment, Food and Rural Affairs; increase investment in the science and research that is needed to develop sustainable agriculture; reduce pesticide dependence; and halt and reverse the decline of species. I also believe that it is time to tweak the Natural Environment Research Council’s responsibilities, to ensure that research supports either the climate or biodiversity.

[Anna McMorrin]

My hon. Friend is making an absolutely excellent speech on this important matter. Does he agree that restoring peat bogs is another way to ensure that ecosystem services work and to restore biodiversity?

[Alex Sobel]

Absolutely, and that is something else we could include in the environment Bill.
