BBC Radio 4 documentary on Vertical Farming

Presented by Ella McSweeney. By 2050 the population of the world is expected to grow to over 9 billion and proponents of "vertical farming" believe growing food in cities would use less land and resources than traditional outdoor methods, reduce transport costs and fossil-fuel emissions.

As vertical farms start to spring up in Sweden, Vancouver and the Netherlands, Ella McSweeney investigates whether they could provide a cost-effective solution that will increase yields or if it is just another example of head in the clouds utopian thinking.

Prod: Clare Walker.
