Farming: Going Underground with Hydroponics
by Imogen Berryman
What's Going On Here?
Researchers at the University of Nottingham have patented a new system to tackle food supply security. Deep Farming, turning abandoned coal mines and tunnels into farms, has the potential to allow us to provide food in non-traditional ways.
What Does This Mean?
The name of the game is ‘hydroponics’ which simply means growing stuff without soil.
Crops are grown in nutrient-rich water or suspended in the air and sprayed with water and nutrients. Artificial light in the form of LEDs is used to mimic photosynthesis. The method is expected to be used for crops such as leafy greens, herbs, strawberries, mushrooms, carrots, aubergines and others. Here’s a curious.graphic to show what it can look like:
Why Should We Care?
The global population expected to hit 9 billion by 2050 with most strain being on urban areas that lack space to farm. One small deep farm can produce ten times more than on the same area above ground.
How’d ya like them apples?
Not only do local & seasonal veggies taste banging... but they don't have the air miles that Peruvian asparagus has!
