We hear about a robot which scans weeds then zaps them with electricity. It uses artificial intelligence and its creators say it'll allow farmers to target specific areas and tackle weeds that have become resistant to chemicals.
We discuss the benefits of smaller, greener and autonomous machines on farms, but ask whether this developing technology is all good news for the farmer.
And celebrating the people working to tackle the challenges facing food: Radio 4’s Food Programme presenter, Dan Saladino, describes what he's looking for in the BBC Food and Farming Awards' 'Food Innovation' category.
Presented by Caz Graham and produced by Beatrice Fenton.
