Solar Farms and Food Production

Tuesday 26th November 2024 Lords Chamber

Question

15:09

Asked by

[Lord Fuller]

To ask His Majesty’s Government what steps they are taking to safeguard the overall quantity of agricultural land for food production in the light of recent proposals for solar farms.

[The Parliamentary Under-Secretary of State, Department for Environment, Food and Rural Affairs (Baroness Hayman of Ullock) (Lab)]

My Lords, the Government recognise that food security is national security. We will champion British farming and protect the environment, and we are committed to maintaining strong protections on agricultural land to ensure that our mission to deliver clean power will not come at a cost to food production or security. We are confident that the rollout of ground-mounted solar will not affect UK food security.

[Lord Fuller (Con)]

My Lords, you cannot eat a solar panel, yet very soon, a large proportion of our most productive and versatile farmland could be covered by them. Earlier this month, I tabled a Written Question asking the Government how much land was being considered for solar farms under the Nationally Significant Infrastructure Projects programme and the answer came back that just two farms of 1,400 hectares were being considered. In the last few days, the Eastern Daily Press has reported proposals for 7,000 hectares of farmland for solar panels in Norfolk alone, and I know that other Members have the same experience in other parts of the country. The Government have quite simply lost control of the numbers. Can the Minister say whether the upcoming land use strategy will explicitly stop the conversion of grades 1, 2 and 3 land, and does she agree that the NSIP programme is being abused by the aggregation of a large number of small proposals into one? Does she also agree that Britain will starve if all we have to eat are solar panels?

[Baroness Hayman of Ullock (Lab)]

First, I reassure the noble Lord that estimates suggest that ground-mounted solar used just over 0.1% of land in 2022, and we expect any future rollout to take up a very small amount of agricultural land. The large solar farms that I have information about are not on any grade 1 or grade 2 agricultural land, as far as I am aware. However, the noble Lord makes the very important point that the land use framework will be critical in how we manage what our land is used for. Is it used for energy, housing or farming, and so on? We expect the Green Paper to be published for consultation in the new year and I urge all noble Lords to read it and take part in the consultation.

[Lord Krebs (CB)]

My Lords, the Minister referred to the long-awaited land use framework, which she helpfully announced is due to be published in the new year. I would like to ask whether, at the same time, her department has considered what skills and data will be required to use the land use framework to inform decisions such as the one that is being debated in this Oral Question?

[Baroness Hayman of Ullock (Lab)]

As part of the consultation and the development of the land use framework, we are intending to engage with a very broad range of respondents in order to have meaningful co-design, and resources absolutely have to be part of that.

[Baroness Bakewell of Hardington Mandeville (LD)]

My Lords, creating energy through solar farms is vital to ensuring a mixed energy supply. It is also vital to use grade 1 agricultural land for producing food. In Canada, crops are grown under solar panels—agrivoltaic farming. Studies have shown that some crops thrive when grown in this way. This not only reduces carbon emissions but doubles up on the use of land. Are the Government looking at agrivoltaics as a way of producing food and sustainable energy?

[Baroness Hayman of Ullock (Lab)]

As the noble Baroness rightly points out, solar generation can be co-located with farmland. Many projects, for example, are designed so that livestock grazing can continue, and on the point she made on arable, there is some evidence that it can be better for growing and for nature if there is solar generation on the field.

[Baroness McIntosh of Pickering (Con)]

Is the noble Baroness following closely the test case of the tenant farms in Old Malton, bearing in mind that 48% of all farms in North Yorkshire are tenanted? They are about to be thrown off the land in favour of a solar farm, exactly as my noble friend has described. Will she watch this case very carefully and ensure that no land is taken out of productive farm use when solar panels could go on warehouse and other roofs, which are much more appropriate than farmland?

[Baroness Hayman of Ullock (Lab)]

Regarding tenant farming, the noble Baroness I am sure will be aware that we have announced that we are appointing the first ever commissioner for tenant farming. Clearly, part of their role will be ensuring that we have a fair, balanced, collaborative relationship between tenants and landowners. Part of that relationship will be to ensure that we do not have the kinds of scenarios that she refers to—so, absolutely, we will keep a close watching eye.

[Lord Trees (CB)]

My Lords, this is about a lot more than solo farms. Financial bodies are buying up estates and farms and planting trees, aided by large subsidies, then selling off the new woodlands to offset carbon emissions. We do need tree planting in the UK, but this irreversible change of land use is continuing unabated and we are losing food production capability. Can the Minister tell us, by letter if need be, the current rate of irreversible loss of agricultural land? If we do not know that, should not His Majesty’s Government be monitoring it?

[Baroness Hayman of Ullock (Lab)]

I am very happy to write to the noble Lord with the detail on this but, as I said earlier, we expect only a very small percentage of land to be taken up with solar farms, as raised in the Question. Also, it comes back to the central importance of developing a fit-for-purpose land use framework. The reason we need to do that has been shown by the kinds of questions that have come up today.

[Lord Roborough (Con)]

My Lords, I refer the House to my interests as set out in the register. Replying to my Written Question of 4 September, the Government stated that

“Ministers consider all the evidence and views on both positive and negative impacts … with reference to the relevant National Policy Statement”.

This was in relation to the Secretary of State’s decision to approve large new solar farms immediately post election in Lincolnshire, Suffolk and Cambridge. Can the Minister help the House to understand why the sacrifice of grade 2 and grade 3 land in this case was apparently given so little weight?

[Baroness Hayman of Ullock (Lab)]

The noble Lord has not said which solar farms he is referring to, but a number of large solar farms have been approved in East Anglia recently. With regard to the Sunnica energy farm, which he may be referring to, I am aware that the examining body considered the impact on farming to carry moderate negative weight. However, the Secretary of State concluded that it carried “slightly” negative weight, which is why it was overruled in favour of allowing permission. My understanding is that it was grade 3 and below land, not 1 and 2, but I am happy to check that.

[Lord Hain (Lab)]

My Lords, I commend my noble friend the Minister’s sensible response to this issue of balancing food with land use in general.

However, does she agree that these rants which we got from the opposite Benches against solar power, wind farms—onshore wind farms—when they were in government and refusing to strike a deal with offshore wind through a sensible strike price, are in defiance of the reality of the climate emergency which we have just seen with the terrible flooding across the country in recent days?

[Baroness Hayman of Ullock (Lab)]

My noble friend raises a really important point. In a nutshell, we have to recognise that climate change is a much bigger threat to farming and to our food security, and we have to take action to secure that. A move to renewable energy is a central part.

[Lord Stirrup (CB)]

My Lords, I get the sense from this Question that it is being viewed as a somewhat academic problem that will be solved by government fiat. However, if we are to have a robust and resilient food production capability in this country, does it not depend on agriculture becoming an economically attractive proposition for those who engage in it? Is that not much more to do with the prices that farmers receive for their produce than with things such as inheritance tax? What action will the Government take to look at those pricing structures to ensure that those who actually produce our food get a decent return for their efforts?

[Baroness Hayman of Ullock (Lab)]

The noble and gallant Lord makes an extremely important point. Farmers have had their prices pushed down for years. I was looking at milk prices today. They seem to be doing okay at the moment, but part of the problem is that there is no stability. We need to look at how we bring stability into farming. The Groceries Code Adjudicator does so much, but we need to do much more than that. It is certainly an area that my honourable friend the Farming Minister is keen to move forward on, and I work very closely with him.
