06/03/2025 - What do Trump's tariffs mean for global agri-trade?, James Dyson's farm, sustainable potatoes

American farmers are being urged to produce more by their president. Mr Trump has imposed 25% tariffs on goods, including agricultural produce, from Canada and
Mexico, and both countries are imposing retaliatory tariffs on American goods. As is China, which is the biggest market for US agriculture products.
So what might this all this mean for them, for us and for global trade?

For This Natural Life on BBC Radio 4, Martha Kearney visits Sir James Dyson on his farm in Somerset to hear what the natural world means to him, and how that is being reflected in his approach to farming.

Continuing our topic this week: supply chains, the many hands food goes through on its way from farm to fork. Controlling what happens at every stage can be a challenge, but that's what one Welsh producer is trying to do so they can make the supply chain more sustainable.
