Global Biodiversity and Ecosystems: National Security

Debate between Adrian Ramsay and Blake Stephenson

Thursday 3rd September 2026 Westminster Hall

[Adrian Ramsay]

Yes, of course I share that frustration. I am pleased to see many Members, from lots of parties, in the Chamber for this debate. We need to increase those numbers and rebuild the national consensus we had on climate. I hope we can have such a consensus on nature restoration and climate adaptation. We all need to tackle the myths and make this debate less fractious and more about bringing people together than driving culture-war wedges. We can do that with how we put forward the solutions that are needed.

Nowhere in this debate are the threats clearer than with regard to food security. This year, water scarcity and drought threaten food production. As all of us representing rural constituencies will be aware, the UK’s agricultural sector has suffered three of the five worst harvests in the past decade, and this year will almost certainly add to that record.

[Blake Stephenson (Mid Bedfordshire) (Con)]

Will the hon. Gentleman give way?

--- Later in debate ---

[Adrian Ramsay]

I will. I am being generous with interventions, which will mean we wait longer before we get to more speeches, but I trust that those intervening are conscious of that.

[Blake Stephenson]

The hon. Gentleman is being extremely generous, and I thank him for that. On food security, like many hon. Members with rural constituencies, I met farmers over the summer. Many told me that they want to build their own reservoirs and extract water dynamically from rivers so they can use that water when it is needed. Does he agree that that is a very simple regulatory change that the Government could make, which would support our farmers in adapting to climate change challenges?

[Adrian Ramsay]

I agree with the hon. Member; that is something that farmers in my constituency have raised with me frequently. There must be solutions to the growing problem of far too little water at some times of the year and far too much water at other times. The solution he outlines is part of how we seriously step up our water management work.

The UK imports around 40% of its food from overseas. Our over-reliance on global markets for food and fertiliser exposes the UK to supply shocks that could make the cost of living crisis much worse. Food security is not simply about producing more food; it is about the resilience of the entire system of agricultural production, including soils, water, fertiliser, feeds, distribution, international markets and the natural systems upon which they all depend. We also depend on international food markets, global supply chains and a stable international system, so protecting critical systems abroad is not simply an act of environmental justice; it is an investment in our own food security. [Interruption.] I hear you, Sir Desmond, but I have been very generous in the number of interventions I have taken. Had I not been so, there would be a much longer list of speeches for later, so I will persist for now.

There is still hope. The Joint Intelligence Committee assessment does not simply describe the threat; it identifies remedies, as it recognises that nature recovery strengthens resilience. Nature restoration and reducing human pressures on nature are both essential. We need to approach nature not as an environmental policy sitting outside national security policy, but as delivering national security benefits and integrated into all areas of policy.

The Government have levers to begin this wide-scale transformation, including fully funding the national tree plan; expanding the sustainable farming incentive; investing in natural flood management schemes such as river renaturalisation and wetland restoration; regenerating soil health to boost resilience for food production; restoring rivers and wetlands to rehabilitate freshwater habitat, flood protection and drought resilience; restoring peatlands for carbon storage and natural flood management; establishing more broadleaf woodland to enhance habitat for biodiversity and landscape-scale resilience; and converting to nature-friendly and climate-resilient farming. All those measures will contribute to maintaining the ecological functions on which we depend.

We need a stronger institutional approach to treating critical natural systems as national infrastructure and to establishing mechanisms to strengthen resilience and adaptation. That means recognising that healthy, natural systems are themselves a form of critical infrastructure.

On the question of transparency, Parliament should have full, unredacted access to the national security assessment as a matter of urgency, to scrutinise the evidence and ensure that our response as a nation is commensurate with the threats. If the Government want the public to become more resilient, the public must be trusted with the facts.

Historians will write about our decisions and future generations will judge us for them. They will recount how we knowingly gambled with global stability, the health of the natural world and the safety of human life and called it a growth agenda. As nature decline is a top-tier threat against the economy, weakening statutory protections and falling short of international obligations directly harms our economy and risks future prosperity. There is a temptation in politics to address environmental policy as an optional extra. The Government no longer have the luxury of time, and it would be a dereliction of duty by everyone in the House to disregard these warnings.

We need a Minister responsible for co-ordinating resilience to move from a managed decline approach to proactively investing in safeguarding for the future, because this is a cross-Government issue that needs to be addressed at scale. The Prime Minister has created a No. 10 for the north, but we need a No. 10 for the future, in the form of a dedicated climate protection unit in the Cabinet Office to drive the scale and pace of work required to restore nature and protect the public. Nature security is national security, and protecting the natural foundations of our country and our planet is ultimately protecting the security of life itself.
