COP30: Food System Transformation

Ann Davies Excerpts

Tuesday 14th October 2025 Westminster Hall

[Pippa Heylings]

I thank my hon. Friend for that, and I applaud her constant advocacy in Parliament on behalf of farmers.

The second part of the debate is about the conference of the parties and how we can bring about legally binding obligations that translate into exactly the kind of measures my hon. Friend talked about. In just a few weeks, world leaders will come together at the global climate summit, COP30, which will be held in Belém, Brazil, in close proximity to the Amazon rainforest. It is being held there deliberately to symbolise the Amazon rainforest’s critical role in global climate stability.

In the lead-up to COP30, I hope this debate today will allow us to consider why this summit is expected to finally be billed as the nature, food and climate COP, putting food systems at the heart of the climate agenda for the first time, and rightly so, because the way we grow, produce and consume food is one of the biggest drivers of the climate and nature crises and one of the most powerful levers we have to solve them. At the same time, climate change is one of the most significant threats to our food production and national security.

Why does COP matter? We have come a long way since the Kyoto negotiations in 1997. That was the first time that countries around the world agreed global governance arrangements to address the shared challenge of global warming. At the time, we were hurtling towards a catastrophic 4°C or even 5°C world, so what a feat it was, unknown in any other sector or on any other issue, to create a framework agreement between 198 parties—197 countries or states and the European Union—to stabilise greenhouse gas concentrations at a level that could help to prevent dangerous human-induced disruption of the climate system. Through dialogue, negotiation and finance, the COP process has brought about legally binding agreements—the Kyoto protocol and then the Paris agreement in 2015—where we all agreed that we have a common and interdependent future, and that we need to do everything possible to keep global warming below 1.5°C.

The Amazon rainforest has been called the lungs of the planet for its ability to capture and store carbon. Yet, right now, the rainforest is gasping for breath as we perilously approach the tipping point where the Brazilian rainforest switches from being a huge sponge, store and carbon sink to being a source of carbon emissions, due to massive deforestation and degradation through land use change. That is why, now more than ever, we need to ratchet up our collective ambition.

I know that rainforest well, and I know what it means to the many indigenous and local communities that depend on it, having worked professionally on climate and nature negotiations for more than a decade in South America, in the countries that share the Amazon: Peru, Colombia, Ecuador, Bolivia and Brazil. I was part of the UK’s largest international climate policy programme in the region, and latterly I worked as the global team lead for the UK’s international £100 million climate and nature programme, the biodiverse landscapes fund. Since 2010, I have seen at first hand the internal workings, impacts, successes and failures of three relevant UN COP processes—the climate COP, the nature COP and the avoiding desertification COP—working alongside Governments and non-state actors such as businesses, scientists, local communities and local governments.

I know how long people have argued for food systems to be a central pillar of the climate framework. Our own independent Climate Change Committee, in its seventh carbon budget, highlighted the importance of agriculture and land use change in meeting our climate targets. I therefore want to make three points today. First, the transformation of food systems is essential for climate action, food security and nature restoration. Secondly, this transition must be just, supporting our farmers and animal welfare as we change how food is produced. Thirdly, the UK must show renewed leadership at COP30 by leading from the front, with the Prime Minister, and by committing to sign a new global declaration on food systems.

Why does food system transformation matter? The EAT-Lancet Commission announced that even if fossil fuels are phased out, the world will breach 1.5 °C because of emissions from food systems alone. Unsustainable food systems are driving deforestation, soil degradation, water pollution and marine biodiversity loss. Globally, agriculture and land use are responsible for almost 60% of biodiversity loss.

Exeter University research revealed this week that we have now reached the first catastrophic tipping point, with warm water coral reefs facing irreversible decline, threatening nature, food security and the livelihoods of hundreds of millions of people—a moment many of us hoped we would not reach. Closer to home, the Energy and Climate Intelligence Unit recently found that wheat lost to storms and drought over the past five years could have produced more than 4 billion loaves of bread—the equivalent of an entire year’s supply for the UK.

There has been a strong build-up to COP30 in Belém, which is expected to produce a declaration on food systems, building on discussions at the Bonn climate conference and the COP28 declaration on sustainable agriculture, resilient food systems and climate action, which the UK signed.

[Ann Davies (Caerfyrddin) (PC)]

COP30, as with past COPs, requires us to be more sustainable, and that includes food production, as the hon. Member said. In Caerfyrddin, we have a public farm producing vegetables for schools and residential homes, so public land is being used for public benefit. Why can all local authorities not follow suit, supported as we were by shared prosperity fund funding, and use public funds and public land for the public plate?

[Carolyn Harris (in the Chair)]

Order. I remind Members that interventions need to be short, not a speech.

[Ann Davies]

No, it is not a speech. Thank you, Mrs Harris; I appreciate your guidance. Does the hon. Member agree with that sustainable and seasonal way of reducing food miles by using public land?

[Pippa Heylings]

I will perhaps come back to that a little later, but I agree completely about the importance of the SPF, as well as the sustainable farming incentive. In my constituency of South Cambridgeshire, we have public land—council land—working on regenerative agriculture with farmers, to provide the food we need. We need the stability and certainty of the SFI for our farmers.

The priorities it is anticipated will be negotiated at COP30 include deforestation-free supply chains, nature-positive farming, support for family farms and sustainable fisheries. This transformation has to be just, and that is as important here at home as it is globally. Farmers have always been on the frontline of climate change, as stewards of our countryside and producers of our food, and because they are struggling with the unavoidable impacts we now face. They must be at the heart of our solution.

The Liberal Democrats have been clear that the transition to sustainable farming cannot be done to farmers; it must be done with them. However, progress has been slow, and the uncertainty surrounding the sustainable farming incentive risks undermining the confidence and stability that farmers need if they are to continue to invest in regenerative agriculture, local food networks and diversified protein crops, as proposed by the National Farmers Union. Improving soil health, supporting pollinators and keeping farm businesses viable makes business sense too. As Martin Lines—the chief executive of the Nature Friendly Farming Network, who farms in Cambridgeshire—says, nature-friendly farming plays a “vital role” in building resilience to weather extremes. He says:

“Practices like improving soil health, using cover crops, and integrating habitats into fields are helping farmers stay productive while cutting back on inputs.”

We also call for a just transition in food and farming, as does World Animal Protection. At home, we must match words with action. The Liberal Democrats would accelerate the delivery of the long-promised land use framework, aligning food, farming and biodiversity policy. We would protect and strengthen the sustainable farming incentive and deliver it now. We would support a just transition for farmers and animals, reduce food waste across the supply chain and champion local, sustainable food production to boost rural economies and resilience.
