Levelling-up and Regeneration Bill

Baroness Willis of Summertown Excerpts

Committee stage
Wednesday 3rd May 2023 Lords Chamber

[Baroness Taylor of Stevenage (Lab)]

My Lords, I will speak to the amendment submitted in the name of my noble friend Lady Hayman of Ullock, who does not yet have London-style transport in Cumbria and so unfortunately this evening has had to leave to get her last train. I hope she will get there eventually.

Green-belt land makes up nearly 13% of England’s land, as my noble friend Lady Young has said, yet there is no statutory basis or even guidance for the role of green belts in contributing to net zero and environmental targets. This is a major problem, and almost certainly contributes to public confusion about what is green belt, what is a green-field site and what is green space.

Contrary to public perception, the green belt is not protected for the environment. There is no green-belt policy with weight directing or requiring that green-belt land be green or valued for its environmental quality. The laudable fundamental aims and purposes of the green belt designation within the National Planning Policy Framework are focused on protection and separation to keep land open, preventing urban sprawl and regenerating cities, not on the quality of the land itself. With no standard of environmental quality expected, there are many parts of the green belt which are left to deteriorate and become threatened due to “scrappy bits of land” being targeted by developers.

This point was summarised squarely in the report of the House of Lords Land Use in England Committee, which noted that

“policies to improve its beneficial and multifunctional use are lacking. Central to this is the disconnect between planning policy which is responsible for green belt, and the range of emerging policies which seek to improve the benefits we get from nature”.

As my noble friend Lady Young said, there is disconnect between planning policy and all the environmental policies that we are thinking about.

Our green-belt land must work harder. We know that green belts, which make up 13% of our land, are potentially a spatially protected reservoir of natural capital assets and ecosystem services. The green belt’s multifunctional uses and benefits could be enhanced to increase the connectivity of woodlands and hedgerows; to restore wetlands and grasslands; to create new habitats and enhance biodiversity; to clean our air and water; to improve soil quality; to increase sustainable food production; to provide cooling to counter the urban heat island effect; to provide physical and mental health benefits for citizens; to protect our communities from floods and storm surges; to store excess water; to recharge our aquifers; and, crucially, to sequester carbon. In short, there is now a strong case for a more proactive and socially productive role for our green belts.

The existing aims and purposes of the green belt are as crucial as ever but, unless they are widened to include environmental quality—including biodiversity and climate change adaptation and mitigation—and recreational access for public health, green-belt land will have no anchor purpose to give material weight for greening. Nor will it provide an explicit link to the emerging nature policies such as local nature recovery strategies, biodiversity net gain delivery sites, local nature recovery networks and proposed wild-belt designations, which we discussed in our debate on a previous group of amendments.

The Government clearly recognise the importance of greening green-belt land, as referenced in the levelling up White Paper, the Bill before us, the Environment Act 2021, the 25-year environment plan and the Environmental Improvement Plan 2023. This was reinforced in, among other things, the Committee on Climate Change’s recommendations for mitigation and adaptation, the Dasgupta review and the post-2020 global biodiversity framework at COP 15. Public Health England has also identified the role that green spaces, including green belts, play in raising levels of health and well-being, reducing health inequalities and improving social cohesion.

In effect, almost 13% of England’s land could contribute to an integrated and holistic solution to the challenges posed by climate change, urbanisation, human health and biodiversity loss, while also strengthening urban and ecological resilience. Our amendment seeks to establish this. It sets out how, in order for green-belt land to play an integral role in meeting national environmental and health objectives and targets, there needs to be a clear, weighted policy with statutory backing and a new purpose that includes, but is not limited to, environmental quality and access to nature. The “not limited” part ensures that this is in addition to the existing fundamental aims and five purposes, and would not replace them.

The amendment would ensure the consideration and identification of further legislation and policy steps in relation to the green belt. It addresses the key barrier to the Government’s objective to green the green belt, and does so through direct consideration of widening its fundamental aims and purposes with regard to its role in contributing to the national environmental agenda.

To support the implementation of this Bill, my amendment asks a Minister of the Crown to publish a report on the possibility of further legislation to widen the purpose of green-belt land in relation to its environmental quality and access, in addition to strengthening related existing and proposed policy provisions. This can be achieved through secondary legislation. This amendment also seeks to ensure that green-belt land policy aligns with and contributes to the Government’s legislative agenda on net zero and biodiversity. In short, the policy needs teeth through recognition in legislation, national policy and the national development management policies. Ultimately, this will direct local authorities to consider green-belt land as an available and critical resource to use in response to climate change, biodiversity loss and demand for access to nature for recreational and health objectives, beyond the benefits of keeping land open.

This report is important as there are a number of parallel consultations and changes across legislation and policy that all relate to or impact green-belt land. The report would consider the recommendations holistically and avoid some of the contradictory outcomes that we have seen in the past. The Bill’s policy paper recognises the imperative

“to make the Green Belt even greener”.

A first step is recognising that statutory purposes for nature recovery, climate change and access to recreation need to be delivered through legislation, which will be considered and proposed through this report.

The amendment represents an opportunity to provide clarity on what this legislation should look like, such that it can align with and contribute to the Government’s environmental policies, targets and delivery mechanisms to address the climate and biodiversity emergencies. As such, we urge the Minister either to consider accepting it or to look at bringing forward a similar amendment on Report.

Amendment 295, moved by my noble friend Lady Young of Old Scone, would provide the statutory basis needed. As she said, it would transpose the existing purposes of green-belt land from guidance in the NPPF into statute, and would add new purposes with regard to climate change, biodiversity, natural capital and public access. This addition to the current fundamental aims and purposes of the green belt would update it to realise the Government’s agenda for greening green-belt land and enhancing its multifunctional uses and benefits to contribute to the Government meeting their targets and pledges, such as 30 by 30 and the 25-year environment plan. We strongly support my noble friend’s amendment.

[Baroness Willis of Summertown (CB)]

My Lords, I speak in total support of Amendment 295, moved by the noble Baroness, Lady Young of Old Scone, and Amendment 312E in the name of the noble Baroness, Lady Hayman of Ullock. I want to add a few brief points to theirs, focusing specifically on why these amendments giving protection to the green belt are so important for our nature in England and the UK and for meeting the targets that we have signed up to both nationally and internationally; those were alluded to in the previous two speeches.

Even though green belts were originally designated as a way to keep clear spaces between cities and stop urban sprawl, they have taken on another role. We cannot ignore that fact. They have become incredibly important refuges and corridors for England’s biodiversity and wildlife.

We have heard about the multiple other ecosystem services and natural capital services that green belts provide, so I will not repeat them, but there is one point that I want to make: we are often told that most people have no access to the green belt, so they do not get the physical and mental well-being benefits of it—but they do, because they can see it. Being able to see green and see nature has been shown in some cases to be as physiologically and psychologically important as being in nature. Therefore, being able to have a view of nature from the city is as important as having access. Access is also fantastic, but it is not a reason to do away with the green belt. So while green belts started as one thing, they have changed to provide something else. They have become much broader in this. They have become green spaces that are critical for nature and ecosystem services.

So what is the problem? Why are we all standing here speaking about green space and the green belt? As has been alluded to, green belts are under huge pressure right now. I tried to dig down to understand why they are being put forward for housebuilding; surely the protection we have in place already is enough. Well, it is not, because in the National Planning Policy Framework you are allowed to change the use of green-belt land under exceptional circumstances. Our housing crisis and local authorities’ need to meet housing targets are being used by many counties up and down the country as an exceptional circumstance. That is why there is now so much pressure on the green belt: it is the use of that phrase, “exceptional circumstances”. This is certainly the case in my own city, Oxford, where around 8% of the green belt on the edge of the city is in the local plan but most of our housing development will be on other counties’ green-belt land. We have sort of shifted the problem out from the city boundary.

In a recent report, the countryside charity CPRE beautifully illustrates the trend of increased pressure for housing on the green belt. Between 2015 and 2020, the number of housing units completed on greenfield land within the green belt was around 17,700, but there are currently 260,000 homes proposed in advanced local plans. So, in a matter of three years, we have this massive increase of people looking to the green belt to solve their housing problems.

My Lords, I add my thanks to those of the noble Earl, Lord Howe, to my noble friend Lady Young for her tireless commitment to the environment, very well demonstrated in these three groups of amendments that she has put before the Committee today.

According to the Woodland Trust, ancient woodland covers just 2.5% of the UK and is protected because it is an irreplaceable habitat. Such woodlands are rich in wildlife and a vital component of the British landscape. My noble friend outlined with great clarity the provisions she had been assured in October 2021 would be incorporated in forthcoming planning law. The Government’s own planning guidance on ancient woodland says:

“Ancient woodland takes hundreds of years to establish and is defined as an irreplaceable habitat. It is a valuable natural asset, important for … wildlife (which include rare and threatened species)—there is also standing advice for protected species … soils … carbon capture and storage … contributing to the seed bank and genetic diversity … recreation, health and wellbeing … cultural, historical and landscape value. It’s any area that’s been wooded continuously since at least 1600 AD. It includes … ancient semi-natural woodland mainly made up of trees and shrubs native to the site, usually arising from natural regeneration … plantations on ancient woodland sites—replanted with conifer or broadleaved trees that retain ancient woodland features, such as undisturbed soil, ground flora and fungi. They have equal protection in the National Planning Policy Framework. Other distinct forms of ancient woodland are … wood pastures identified as ancient … historic parkland, which is protected as a heritage asset in the NPPF”.


If all that is genuinely the Government’s position, why would they not want to support my noble friend Lady Young’s amendment? It is a very important issue, and we urge the Minister to accept the amendment.

[Baroness Willis of Summertown (CB)]

My Lords, I too fully support Amendment 300 proposed by the noble Baroness, Lady Young. A number of the points that I wanted to make have already been made, so I shall be brief.

One key thing we keep losing sight of in the discussion about ancient woodland is the many additional services that ancient woodland provides to our landscapes and to nature. The first one, which we did hear about, is carbon sequestration. I looked up the figures for carbon sequestration, and although ancient woodlands will not sequester as much carbon as something like Sitka spruce, for example, they are able to store huge amounts of carbon, both above and below ground. In particular, the fungal communities below ground can store up to 40% more carbon as a result of having these mycorrhizal assemblages. That is really important, because 36% of all woodland carbon is currently stored in these ancient woodlands.

There is a second role I want to flag up. Something that often gets forgotten about is the role of those woodlands in providing really important pollination services. So often, when we look at ancient woodland, it is a patch of trees surrounded by a sea of agricultural land. Some 80% of our crops in this country need pollination services, and pollinators need habitats and foraging places—that is what those ancient woodland patches provide. Without them, you then have to bring in lorries with pollinators in them. We do not want to go down that route. There is very good evidence—not from the UK but from other places in Europe—that if you remove a patch of ancient woodland the yield from the crops is significantly reduced. We need to bear that in mind
