The world’s population is set to rise to 10 billion by 2050 and the large majority will live in cities. It means fewer resources to be shared among many. So how will we feed tomorrow’s cities? To overcome this new challenge, we need to change the way we produce food and create sustainable solutions: permaculture, communal farms, local food. We talk to French director Cyril Dion who tackled some of these questions in his award-winning documentary ‘Tomorrow’.
