The 21st century has seen rapid urbanisation and the global population is now expected to grow to more than 8.3 billion by 2050. Currently, 800m hectares – 38% of the earth's land surface – is farmed and we'll soon need to give over another 100m hectares if we continue to use current agricultural methods. That's not additional fertile land that actually exists though, so some are investigating the potential of vertical farming.
