For fruit and vegetable crops – I’m talking the 7-a-day stuff that most of us need way more of in our diets – it’s a completely different story. Just a few acres, with polytunnels or glasshouses require constant tending, and can employ numerous people doing skilled, interesting, rewarding, socially useful jobs. Fruit and vegetables don’t necessarily need much processing before they reach our plates. We want to eat them fresh – the fresher the better! It would make sense, then, that the most labour intensive, perishable, unprocessed foods are grown in close proximity to urban areas.
