Soil Health

Mary Creagh Excerpts

Thursday 17th November 2016 Westminster Hall

[Mary Creagh (Wakefield) (Lab)]

I beg to move,

That this House has considered the First Report of the Environmental Audit Committee, Soil Health, HC 180, and the Government response, HC 650.

May I say what a pleasure it is to be here with you today, Mr Bone, to discuss the vital issue of the nation’s soil health? I believe this is the first time that the UK Parliament has ever discussed the health of our soil, which is a vital part of the nation’s ecosystems. I warmly welcome the Minister to her post—I know we will have a good discussion today—and my hon. Friend the Member for York Central (Rachael Maskell), who is the Labour Front-Bench spokesperson on this issue. I am grateful to Mr Speaker and to the House for this first ever debate, which is on the Environmental Audit Committee’s report into soil health.

I begin by thanking my Committee colleagues for their work and all the other hon. Members across the House who have a long-standing, informed interest in protecting the environment. One of the first findings of our report is that soil is a Cinderella environmental issue. It is an earthy subject; it is not clear like water, and it receives a lot less attention than air pollution, water quality and climate change. Yet whether we realise it or not, society relies on healthy soil for the food that we eat, for flood prevention and for storing carbon. The UK’s soils are only about 10,000 years old, which is one of the fascinating facts we learnt as we went through our inquiry. Soil supports 95% of the world’s food production —the other 5% is probably fish and perhaps stuff from trees, although trees grow in soil as well—so if soils start going down, human life will follow soon after.

The Government say they want our soil to be sustainably managed by 2030, but we found no evidence that they are putting in place the policies to make that happen. Although healthy soil is a vital tool in the fight against climate change, degraded soils harm the environment and can even contribute to climate change by emitting carbon into the atmosphere, so it is vital that robust mechanisms are put in place to promote soil health and reverse soil degradation. We welcome the Government’s aspiration for UK soils to be managed sustainably, but we need ambitious targets, effective policy and strong enforcement mechanisms to make sure that happens, and we did not see that action.

Let me turn first to the vexatious issue of contaminated land. This is absolutely vital if we are to have a resource-efficient country that uses everything well. That includes brownfield land, rather than taking more land from our beloved greenbelt, which, as we all know as constituency MPs, is a deeply controversial issue.

A key area of concern was the fact that 300,000 hectares of UK soil are contaminated with toxins, including lead, nickel, tar, asbestos and radioactive substances. Those contaminated sites can be a public health risk and can even pollute our water supplies. The contamination is the result of the UK’s proud industrial heritage in areas such as mine and that of the hon. Member for Rochdale (Simon Danczuk). That is not a problem in areas with very high land values, where sites are mostly dealt with through the planning system, so that developers can see what the cost of remediating and cleaning the soil—washing it, which is what actually happens—will be, and they are happy to do that. That happened, for example, at London’s Olympic park: the soil was actually lifted up and washed before the development began. I am sure we are exporting that amazing technology all round the world.

In areas where land values are low, where the local authority owns the land or where rogue developers have failed to clean up before construction, local councils have a statutory duty under part 2A of the Environmental Protection Act 1990 to clean up contaminated land. However, the Government have withdrawn capital grant funding, which enables councils to do that.

Let me give an example from Wakefield of a housing estate in Ossett. It was built in the 1970s on the site of an old paintworks, when environmental regulations were much less stringent than they are today. In 2012, the council discovered that people’s back gardens were contaminated with asbestos, lead, arsenic and a derivative of coal tar, which can cause cancer. Cleaning up that toxic legacy would have cost residents £20,000 to £30,000 each, leaving their homes blighted and unsellable. Thankfully, Wakefield Council secured more than £300,000 from the Department for Environment, Food and Rural Affairs in contaminated land grants to clean up the toxic mess.

However, our inquiry heard that the cut to the capital grant has severely undermined local councils’ ability to tackle the problem. It means that sites such as Sand Hill Park in Gunnislake in Cornwall, Upton Court Park in Slough and McCormack Avenue in St Helens will be left untreated. Many councils simply do not have the resources to investigate contaminated sites, and we heard that councils would be reluctant to investigate a site—rightly—knowing that they could not secure funding for remediation.

There is a real danger that contaminated sites are being left unidentified, with potential harm to public health. Ministers have been clear that relying on the planning regime alone does not solve the contaminated land problem and could exacerbate regional inequalities. There is a risk of no remediation being done, and in some cases the houses were built in Victorian times, so there is no developer to pursue. The Government have not produced an impact assessment that we have seen—I am happy if the Minister wants to correct me—on the cessation of the capital grant scheme, but it is wrong to state, as Ministers have, that contamination can be addressed through the revenue support grant. Correspondence published by my Committee from December 2013 shows the then DEFRA Minister, Lord de Mauley, saying that the Government never intended the revenue support grant to take the place of capital grant funding.

The Government have cut £17 million of funding since 2009-10, leaving just half a million pounds, with the funding essentially being phased out in 2016-17. Capital support grants, not revenue support grants, have financed 80% of the cost of cleaning up contaminated sites. Fewer than 2% of cases have been remediated through other public funding, suggesting that the revenue support grant has rarely been used to meet councils’ statutory responsibilities under part 2A.

Revenue support grant—the clue is in the name, is it not? It is there to help councils with their revenue needs, not these sorts of big capital needs. Some councils facing the biggest problems with contaminated sites are coping with the most severe budget cuts. Wakefield Council is cutting £27 million of spending this year. We believe it is essential that DEFRA provides a dedicated funding stream to decontaminate sites, to use brownfield properly and to have a resource-efficient approach to the planning system. It should be set at the level of the previous scheme—around £19.5 million in today’s prices.

I was concerned to learn that since the publication of our report both DEFRA and the Department for Communities and Local Government have proposed amendments to planning regulations in the Neighbourhood Planning Bill that will curtail the right of local planning authorities to attach pre-commencement planning conditions to brownfield development approvals. The requirement for these conditions to be agreed with developers in advance or be subject to appeal will prevent local authorities from ensuring that site investigation, risk assessment and clean-up works take place before development begins. Furthermore, the CL:AIRE national quality mark scheme, which aims to speed up approval for development on brownfield sites, risks negating or potentially replacing the independent, rigorous and accountable role of the local authority’s contaminated land officer. It is wrong for DEFRA to be relying on local authorities to remediate contaminated land while cutting their funding and introducing new legislative measures that reduce their ability to act effectively.

Let me turn to soil degradation, peat lands and climate change. I was unaware before this inquiry that soil is a massive natural carbon capture and storage system. We hear a lot about CCS, but we do not actually understand that the soil around us is capturing and storing carbon all the time. It stores three times as much carbon as the atmosphere, and we want it to stay there. The UK’s arable soils have seen a widespread and ongoing decline in peat soil carbon levels since the ’70s. Soil degradation increases carbon emissions and contributes to climate change. Each tonne of carbon retained in soil helps us to meet our carbon budgets and slows climate change.

At the Paris conference on climate change last year, the Government pledged to increase soil carbon levels by 0.4% a year. That is a great pledge, and we welcome the ratification today of the climate change treaty, but the Government need a plan to put that pledge into action. I would like to hear from the Minister where that plan is. Without a national soil monitoring scheme to establish a baseline for the nation’s soil, we will not know whether the target is met. The carbon content of soil is vital for growing food—95% of food, apart from fish. Soil degradation could mean that some of our most productive agricultural land, particularly in East Anglia, becomes unprofitable to farm within a generation.

The degradation and decline of peat bogs is particularly troubling, given that peat lands store about 40% of our soil carbon. The Government need to crack down on land use practices that degrade peat, such as the burning and draining of bogs. I welcome the Government’s commitment to publish their report on the carbon and greenhouse gas balance of low-lying peat lands in England and Wales before the end of the year. That research will fill an important knowledge gap, and the Government should use the report to accelerate and improve their peat land restoration programme.

The upcoming 25-year environment plan—we are keen to hear the latest timings for that from the Minister—should set out measurable and time-bound actions that will halt, then reverse, peat land degradation while minimising the impact on farmers. DEFRA’S single departmental plan contains £100 million for the natural environment. Will the Minister tell us how much of that money will be spent on improving soil health? I am concerned that a majority of the projects are based in upland peat land areas, whereas our report highlighted that the problem is in the lowland peat areas. They are the emissions hotspots, and that is where the Government should target their efforts.

I mentioned the need for a proper soil monitoring system. Again, because soil is earthy and dark, we do not tend to see it as something that is important to us as an ecosystem. DEFRA’s ad hoc approach to soil health surveys is inadequate. We would like the Government to introduce a rolling national monitoring scheme, very similar to the one in Wales that we heard about, to ensure that we get a rich picture of our nation’s soils. Data collection is a cornerstone of effective policy, because what gets measured gets done. Without a national soil monitoring scheme, we do not know whether our soils are getting healthier or sicker. Ad hoc studies are just not enough; one survey in eight years is not enough.

A proposal to undertake a repeat of the soil sampling carried out in 2007, which would cost just £156,000 a year, has been submitted to DEFRA since the release of our report. Is the Minister aware of that and does she have any comments about that proposal? Compared with the costs of monitoring air and water quality, this is very small beer, but it is a crucial platform for knowledge building. Soils receive nowhere near equal status with water, biodiversity and air.

The Government have suggested that we could use farmers’ own soil analysis to monitor soil health. That is fine. That approach may provide useful additional data, but it is not a solution because it would be an unrepresentative sample. I know the Minister has a degree in these—

[The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Dr Thérèse Coffey)]

In chemistry.

[Mary Creagh]

Yes, the Minister has a degree in chemistry, so she will know about the importance of representative sampling. Such an analysis would only deal with agricultural soil, but would neglect conservation land, urban and coastal land, forests and most peat lands.

Let me turn to the cross-compliance regime. The Government’s reliance on cross-compliance rules with farm payments to regulate agricultural soil health is not sufficient to meet their ambition to manage our soil sustainably by 2030. The regime is too weak. The rules are too loosely enforced and they rely only on preventing further damage to soil, rather than on promoting activity to encourage the restoration and improvement of our soils.

Crucial elements of soil health, such as soil structure and biology, are not assessed at all in the cross-compliance regime, and there is a minimal inspection regime. Two figures really illustrate the changes in the past couple of years. In 2014 there were 478 discovered breaches of the cross-compliance soil regime, but in 2015, under the new common agricultural policy rules, there were just two discovered breaches of the new conditions, both on the same farm. I am pretty certain that the only reason those breaches were discovered was because there was soil run-off, which probably went into a watercourse. It was not Government inspectors, but the Environment Agency, that saw a polluting incident in a river, allowing the breach to be discovered. In theory, an outcome-based approach is fine, but we need adequate inspection and monitoring. Rules with greater scope, force and ambition are required to meet the Government’s goal to manage soil sustainably by 2030.

I turn briefly to subsidies for maize production and anaerobic digestion. We heard that maize production, when managed incorrectly, also damages soil. This is not just a question for fans of “The Archers”, in which Adam is trying to restore the soil structure in the face of opposition from evil Rob Titchener, who is evil not just because of what he did to Helen, but because of his approach to soil monitoring and restoration. We send Adam every good wish in his low-till approach to improving the land.

Maize production can increase flood risk and contribute to soil erosion. My Committee heard evidence that up to three quarters of a field could be sealed to—or become impervious to—rainfall in maize stubble fields over the winter, which results in the soil run-off that, as I said earlier, damages rivers. There is a very simple method to avoid that, which is roughly ploughing back in the maize stubble. If the Government could think of ways to incentivise farmers to do that, we would be only too happy to hear about them. We need effective regulation of high-risk practices.

Maize produced for anaerobic digestion receives a double subsidy: first through the CAP and then from the UK’s own renewable energy incentives. That is counterproductive and has contributed to an increase in the land used for maize production. The Government’s plan to restrict the subsidy for energy generated using crop-based feedstock is a move in the right direction, but it fails to prevent maize from being grown on high-risk soils. I would be grateful if the Minister set out whether she has any specific plans on that issue.

Before I finish, Mr Bone, I would like to say a few words about the referendum result, a topic that I know is very close to your heart.

[Mr Peter Bone (in the Chair)]

Order. When I sit in this Chair, I have no views on anything.

[Mary Creagh]

Excellent; that is great. I shall carry on regardless, then.

Some 80% of our environmental regulations are shaped by Brussels, and soil is no exception. The European Environment Agency researches trends in European soil health and looks at how cross-cutting policy objectives impact on soil management. It is not glamourous work—getting our hands dirty never is—but it is important for member states, including the UK, working towards the European Union’s target to ensure that by 2020 soil erosion is reduced, soil organic matter is increased and remedial work is underway on contaminated sites. It is important that we are able to meet our 0.4% target to improve soil carbon capture, as we have agreed to do in the Paris agreement. As we leave the EU, it is vital that the Government maintain that target and ensure that UK agencies take over the European Environment Agency’s vital work in this area.

Other Members wish to speak, so I will conclude by saying that soil is crucial to life on Earth. Neglecting soil health will damage our food security, increase climate change and damage public health. DEFRA’s upcoming 25-year environment plan gives us a unique opportunity to place soil protection at the heart of our environmental policy. We must stop seeing soil just as a growth medium and treat it as a precious, fragile ecosystem in its own right—it is the Cinderella of all ecosystems.

We need a joined-up soil policy between DEFRA and the Department for Communities and Local Government in relation to planning. We are pleased that the Government have acknowledged those issues, but now we await action. We want to see specific, measurable and time-limited action to protect our soil. I commend our report to the House, and I look forward to the debate and to the Minister’s response.

[Rebecca Pow (Taunton Deane) (Con)]

I, too, am delighted to serve under your chairmanship, Mr Bone. I am also delighted to follow my Committee colleague, the hon. Member for Wakefield (Mary Creagh), who so ably chaired our inquiry on soil. I was one of the people who persuaded her to hold the inquiry. To many people it might seem a rather odd subject to consider, but I hope that we are demonstrating that we neglect soil at our peril. Soil may not be on your top-10 list of important issues, Mr Bone, but I hope you might change your mind after hearing what we have to say this afternoon and agree that we should all give soil a much higher profile.

The hon. Lady talked about soil and soil contamination, but I will talk about soil in the wider landscape. I hope that some of the ideas in our report will gradually filter into policy, and I am confident that the Minister is listening to some of those views. I am a gardener, I grow fruits and vegetables at home, I was brought up on a mixed farm—such farms treat soil the best—and I have reported on such subjects for many years as a journalist, so I am pleased to be involved in this debate.

Soil is the stuff of life. It is as important as the water we drink and the air we breathe—they are all inextricably linked. Without healthy soils, we cannot produce healthy, sustainable food. Soil is also an important sequester of carbon, as we have already heard, and it plays an important role in climate mitigation. Until we produced our report, many people, even on our Committee, were unaware of that. Soil stores three times as much carbon as is held in the atmosphere, with peat being especially significant. Soil has an important water-cleaning function, as it helps to filter and clean the water as it drains through. Soil also holds water and slows the flow, so it also provides flood resilience. We heard all those things in our inquiry.

I am also a member of the Select Committee on Environment, Food and Rural Affairs, which recently reported on flood resilience. Soil was highlighted in that report. Treating our soil well and increasing the amount of organic matter contained in it will help to hold water and slow the flow into our rivers, which will ultimately help the nation. Taking more care of the land around us would have a cost effect on the economy, because it would save us money if we did not have to react to massive flooding.

I said at the beginning that soil is the stuff of life. Soil is our lifeblood, and it is alive—many people think soil is inert, but it is not. There are more organisms in 1 gram of soil than there are human beings on the planet. Each gram of soil contains: 1 billion bacteria belonging to 10,000 different species; up to 100 invertebrates; and up to 1 km of fungal threads. A square metre of soil can contain between 30 and 300 earthworms.

[Mary Creagh]

The hon. Lady is showing what a brilliant member of the Environmental Audit Committee she has been. I slightly regret that we did not call her as a witness, instead of just as a member of the Committee, because I am learning new things, particularly about fungal threads and water filtration. This is a subject to which Parliament must return.

[Rebecca Pow]

I thank the hon. Lady so much for that intervention. I have talked to many organisations. I literally love soil. It is a fantastic subject in which we all need to get more involved. Darwin described earthworms as nature’s little ploughs. We would not survive without earthworms, because they create the passageways that aerate the soil and allow it to breathe and be healthy, and that allow all the other creatures to go to and fro doing their jobs.

All those creatures are working in the topsoil, directly influencing the food we grow—there is a direct link—yet we understand only 1% of those organisms, which is unbelievable. It is an untapped area. People are getting into it, but it is still so unknown. The hon. Lady mentioned fungi. Trees could not properly uptake nutrients or water without the fungi in the soil, and we would not survive without the trees because they have such an effect on the recycling of the air and all the gases, which is even more reason to look after our soil. That brings me neatly to something I must mention—ancient trees. I am chairman of the all-party parliamentary group on ancient woodland and veteran trees. Ancient woodland is our most biodiverse habitat, but only 2% remains. Ancient woodlands are like our rain forests, and they are a wonderful microcosm of biodiversity, but with the trees we have to include the soil underneath. We should treat it all as one holistic whole.

The soil and those trees should be protected as we protect our national monuments. They are that significant. I am sure that the Minister is listening, and her predecessor was terribly interested in ancient trees. All the diverse little connections are all the more reason to protect our soil.

--- Later in debate ---

[Mike Weir]

I thank the hon. Lady for that intervention. It is a very good point and what she has suggested should be done.

[Mary Creagh]

I wanted to ask the hon. Gentleman about hares, which are one of our most iconic native species. I have just seen that there is a close season on hunting hares in Scotland, but I am not aware that we have a close season for hares in England and Wales. That is problematic, because we had a target to restore the hare population to 1990 levels, and that target has consistently been missed. So will he join me in calling on the Minister to consider the need for a close season on hares in England and Wales?

[Mike Weir]

The hon. Lady has made her point. I think the Minister might object to a Scottish MP calling for a close season on hares in England when we have one in Scotland already. Nevertheless, I am sure the Minister has heard her point.

Much of this issue in Scotland is a devolved matter, but, as has been mentioned, the UK Government have signed up to a scheme, COP 21, to increase soil carbon levels by 0.4% per year. Obviously, there will have to be work with the devolved Administrations to achieve that, since all of them have their own separate schemes.

In Scotland, we recognise that soil is a valuable but vulnerable national asset that requires sustainable and effective management. Although we have talked a lot today about farming, this issues goes much further. In Scotland, as well as farming and food production we have forestry and tourism, which are important and rely on a good natural environment, including a good soil structure. So, throughout the economy, soil is important and we should not just look at it as a purely farming matter; we must expand the areas that we are considering.

I think that it was the hon. Member for Bristol East (Kerry McCarthy) who mentioned flooding, saying how soil management also plays an important role in sustainable flood management. Within the common agricultural policy schemes that are currently operating, at least in Scotland, there is an attempt to persuade farmers to take flooding into account in their farming methods, particularly by leaving flood plains in the areas immediately next to rivers and by not building on those flood plains. Often, when flood plains are built on, there is a problem as floodwater is pushed further down the river. In my area, we have probably expended millions of pounds on flood defences to deal with that problem, because when there are changes in farming practices, sometimes the floodwater is pushed further down the river, causing problems that then have to be dealt with by other methods.

Mention was also made of peatlands. Peatlands constitute a third of Scotland’s soil and they provide many economic, environmental and cultural ecosystems, as well as being important habitats for our wildlife. As far as carbon is concerned, it has been estimated that in Scotland’s peatlands the soil contains 3,000 megatonnes of carbon, which is equivalent to nearly 200 times the net annual greenhouse gas emissions. That shows the importance of soil for climate change and, in particular, the importance of peatlands.

The Scottish Government are seeking to maintain soil carbon in place, but we have to bear it in mind that there is always a conflict about some of these things. For example, renewable energy infrastructure—wind farms, for instance—is often built in areas that are less accessible, and often that is peatland or similar land. There is an offset if we have these renewable energies and clearly we are saving carbon, but at the same time there is a cost to them and we should not lose sight of that cost. The Committee’s report says:

“Current policy aims to minimise losses while facilitating development which delivers economic growth that does not entail disproportionate carbon costs.”

I reiterate that there is a cost and we must find ways of offsetting it.

Also, earlier I made the point about species. One of the things that is being done to support peatland restoration is to provide funding through the rural priorities scheme of the Scottish Rural Development Programme. Some landowners, such as the Royal Society for the Protection of Birds, have carried out restoration on their land, which, in the case of the RSPB, is mostly to do with wildlife but none the less has an important effect on greenhouse gas emissions and on ensuring that carbon is maintained in the soil. Restoration also has side effects. For example, it leads to other species growing. In many cases there is a regrowth of sphagnum moss and the resumption of carbon sequestration.

To sum up, this issue is not just about farming; there is an economic impact on all our rural areas. One thing that worries me—I am sure the Minister will not say too much about it—is farming payments. In Scotland at least, we have been trying to push much of the farming subsidy towards more environmental means to try to ensure the future. If it should come to pass that we leave the European Union, there will have to be a major realignment of farming payments. I urge the Minister and the devolved Administrations to look at the environmental benefits and how they will be maintained in a post-EU world, should that unfortunate calamity come to pass.
