Can small farms feed the world?

What’s the best way to produce affordable food, that’s good for the planet, and can feed us all? Is it even possible to have all three? In this programme, Grace Livingstone visits small and large farms in England and Argentina. She hears the case made for organic farming, and asks if it’s feasible for organic farms to produce enough food to feed a country. At a larger farm, she hears about why farmers rely on fertilisers and herbicides to produce large volumes of affordable food. Is it possible to farm in a way that increases biodiversity and protects the environment, whilst also remaining competitive? And what can we do as consumers to encourage and support greener farming?
