A sustainable global food system in the 21st Century needs to be built on a series of "new fundamentals", according to a leading food expert.

Tim Lang warned that the current system, designed in the 1940s, was showing "structural failures", such as "astronomic" environmental costs.

The new approach needed to address key fundamentals like biodiversity, energy, water and urbanisation, he added.

Professor Lang is a member of the UK government's newly formed Food Council.

"Essentially, what we are dealing with at the moment is a food system that was laid down in the 1940s," he told BBC News.
