Food needs ‘fundamental rethink’

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.
Professor Lang lists a series of “new fundamentals”, which he outlined during a speech he made as the president-elect of charity Garden Organic, which will shape future food production, including:

Oil and energy: “We have an entirely oil-based food economy, and yet oil is running out. The impact of that on agriculture is one of the drivers of the volatility in the world food commodity markets.”

Water scarcity: “One of the key things that I have been pushing is to get the UK government to start auditing food by water,” Professor Lang said, adding that 50% of the UK’s vegetables are imported, many from water-stressed nations.

Biodiversity: “Biodiversity must not just be protected, it must be replaced and enhanced; but that is going to require a very different way growing food and using the land.”

Urbanisation: “Probably the most important thing within the social sphere. More people now live in towns than in the countryside. In which case, where do they get their food?”

Professor Lang said that in order to feed a projected nine billion people by 2050, policymakers and scientists face a fundamental challenge: how can food systems work with the planet and biodiversity, rather than raiding and pillaging it?
