Buy local produce and save the world: why food costs £4bn more than we think

Professor Jules Pretty, of Essex University, and Professor Tim Lang, of City University, in London, said another way of looking at the problem was to assess the national savings that could be made if everything was done differently.
They reckoned more than £4bn a year could be saved if farmers grew organically, farming subsidies were abolished and if consumers shopped for local produce, preferably on their bikes. The issue centres on the concept of "food miles" which refers to the distance travelled by produce from farm to fork.
The scientists tried to assess the added expense of bringing food from around the UK and the wider world to the typical British dinner table. By analysing foodstuffs, farming methods and transport policies, professors Pretty and Lang found that if all of our food came from within 20km (12.4 miles) of where we live we could save £2.1bn a year in environmental and congestion costs.
They also found that if shopping by car was replaced by bus, bicycle or walking, these savings would amount to a further £1.1bn. And if all farms in Britain were to follow organic principles, the costs to the environment would fall from £1.5bn a year to less than £400m, a further saving of £1.1bn. "Food miles are more important than we thought and buying local is more important than buying green," Professor Pretty said at the Science Media Centre in London. "It's better to buy a local lettuce than an organic one from the other side of Europe."
