Climate Change and Biodiversity: Food Security

Baroness Young of Old Scone Excerpts

Thursday 8th September 2022 Lords Chamber

[Baroness Young of Old Scone (Lab)]

My Lords, I declare my interests as chair of the Woodland Trust, as a commissioner at the Food, Farming and Countryside Commission, and as vice-president of a range of environmental and conservation charities. I commend and welcome the maiden speech of the noble Baroness, Lady Willis; it is really great to have another biodiversity freak on board. I very much endorse the statements made about the powerful contributions that excellent scientists have made in this Chamber—it is great to have the noble Baroness here.

Climate change, biodiversity and food security are totally and deeply interdependent, both globally and nationally. The Armageddon in Pakistan described by the noble Baroness, Lady Mobarik, is absolutely an example of that, and we will increasingly see other examples. Climate change, biodiversity decline, and food and survival catastrophes for people across the world will become more and more frequent.

Right now in the UK, apart from any of the international actions that we can take, we need to ensure that policies are in place that focus on the environment and climate change impact not only of our food production but on our food production. Both are equally important. The current international tensions make it even more important that we address issues of food security in this country. The UK will never be self-sufficient in food production until we learn how to grow pineapples in Kent—that may yet come, of course—but there are some commodity groups where we could produce more of our own food. We are currently only 16% self-sufficient in fruit, 54% in fresh veg and 71% in potatoes, so we could do more. I raise this issue of self-sufficiency in these commodities simply to indicate how that in itself raises a challenge. Expanding potato production, for example, would need more land and water, and potatoes are notoriously hard on soils.

That takes me to the key point on which I want to focus. There are many in the Chamber today who will have guessed that I want to bang on about land use. There are many competing demands for land in this country: agriculture and food production; biodiversity; carbon sequestration; generation of energy; timber production; water protection; development; housing; infrastructure; and land that people can access close to where they live and gain the health and spiritual benefits that those services provide. There are more land needs and pressures than, at the moment, it would seem we have land for. The Cambridge Conservation Initiative has calculated that, if we were simply to use land in the way that we do currently, we would need a third more land than we have. The risk is that we consider all these land-use needs as being in competition and that we continue to make decisions about them in silos.

As I said, many noble Lords will have heard me banging on for years about the need for a land use framework for England, which would provide support for decision-makers at all levels in breaking down the silos of decisions about land use. I simply say that Scotland is on its third land-use strategy. I know that our new Prime Minister does not think a lot of the First Minister of Scotland, but she may have got it slightly more right on this occasion in having a third land-use strategy. It brings into one policy framework the land aspects of a whole range of issues: food production, biodiversity, climate, economic development and social justice. We are not making any more land. I thought it was really fascinating that we have lost sight of the theme of the post-war settlement in this country—of the three capitals: of labour, capital and land. We have lost sight of the fact that scarce land is as important a national asset as capital and labour. I commend that thought to the Treasury and the new Chancellor.

As has been said, the Government recently agreed, in their response to the Dimbleby food strategy, that England needs a land-use framework—hurrah—but we appear to have rather a different Government today, so I ask the Minister to reassure the House that the Government are still committed to developing and launching a land-use framework by 2023. I urge him to widen the perspective of the strategy to cover not just the narrow range of Defra issues of carbon biodiversity and food production, but also the whole range of land-use pressures, especially infrastructure, housing, the built environment and energy generation. In particular, the framework needs to be completely seamless with whatever changes to the planning system the Government are working on. I also press him to give us an indication of the Government’s current intentions on planning reforms, because at the moment they have kind of gone into a hole.

Some other wider government policy currently seems a bit confused as well. As the noble Baroness, Lady Boycott, said, the solar panels versus food security argument is unreal, although I do not think the new Prime Minister has yet twigged that. If the Government were to tackle, systematically and urgently, a major programme of energy efficiency and retrofitting in all domestic and commercial properties, and if they were to restore their own zero-carbon new homes policy that was cancelled in a rather cavalier fashion by George Osborne in 2015—if these two things were done—we would need less energy and we would not need solar panels on farmland, because solar power would be generated intrinsically on buildings.

The biodiversity versus food security and carbon action versus food security dichotomies are also unreal. Modelling commissioned by the Food, Farming and Countryside Commission shows that multifunctional land use, where the same land delivers for a range of purposes, means that we can have enough land for all our needs and one land use need not be at the expense of another. Many of the decisions about the best multifunctional land use are made, in reality, at local level by myriad land managers. Whatever framework the Government develop needs to be able to inform decision-making processes below national level, at regional and local level, involving land managers and landowners of all kinds.

Let the science speak: when the land is used effectively in a multifunctional way, we can see a wholly revitalised landscape that is rich in both food and nature and combats climate change. This is about being smarter with the finite land we have. At the risk of a pun, we need to be able to have our land and eat it. Perhaps the Minister will be able to tell me whether he is still committed to a land-use framework that will be broader than just the Defra issues and how the planning reforms are going.

Before I finish, at this tense time for the country in a whole variety of ways, I commend the Queen’s Green Canopy initiative, which Her Majesty has hugely supported and has very graciously allowed the Woodland Trust to be involved in. Her Majesty knows about these things.
