This galloping urbanization involves many challenges that cities will have to respond to, first and foremost, that of food.

The rise in world food prices, the imbalances caused by the covid 19 pandemic, climate change, further increase the pressure on urban food systems.

Rooftop vegetable gardens, shared gardens, above-ground agriculture, etc. will they be enough to feed billions of city dwellers?
