24/03/26 Middle East conflict and supply chains, processing shellfish, medieval farming.

Conflict in the Middle East will continue to have an impact on global supply chains even after hostilities cease, so say The Agricultural Economics Society who are marking their 100th birthday at their annual conference in Oxford. Will it impact food prices in the supermarket too?

Seafood processors say they're concerned that imports of shellfish won't meet new regulations which recognise crustaceans like lobsters as sentient beings which can feel pain. Under the Animal Welfare Strategy they must be dispatched before they're cooked, as painlessly as possible.

All week we're taking a step back in time, and looking at the history of farming over the last couple of centuries. Today we're rewinding to experience the country's last remaining example of the medieval three field crop rotation system, in the village of Laxton in Nottinghamshire.
