The future of food: inside the world's largest urban farm – built on a rooftop
Written by Jon Henley
In Paris, urban farmers are trying a soil-free approach to agriculture that uses less space and fewer resources. Could it help cities face the threats to our food supplies?
On top of a striking new exhibition hall in the southern 15th arrondissement of Paris, the world’s largest urban rooftop farm has started to bear fruit. Strawberries, to be precise: small, intensely flavoured and resplendently red.
They sprout abundantly from cream-coloured plastic columns. Pluck one out to peer inside and you see the columns are completely hollow, the roots of dozens of strawberry plants dangling into thin air.
Since you’re here …
… we have a small favour to ask. More people are reading the Guardian than ever but advertising revenues across the media are falling fast. And unlike many news organisations, we haven’t put up a paywall – we want to keep our journalism as open as we can. So you can see why we need to ask for your help. The Guardian’s independent, investigative journalism takes a lot of time, money and hard work to produce. But we do it because we believe our perspective matters – because it might well be your perspective, too.
If everyone who reads our reporting, who likes it, helps fund it, our future would be much more secure. Support the Guardian – it only takes a minute. Thank you.
