In an effort to provide passengers with amenities beyond transportation, Taiwan has chosen an unusual location for vertical farming, an underground metro station.

Located at capital city Taipei’s Nanjing-Fushing Station, the 40 square-metre ‘Metro Fresh’ hydroponic farm grows lettuce under LED lighting in a sterile environment to eliminate the use of pesticides and herbicides.

Smart farms are less labor intensive and use technology to increase yields and mitigate weather fluctuations.

"Right now our production yield is about 180 bags of lettuce, each bag is 200 grams. We can produce 180 bags of lettuce each week," says Winnie Chan, deputy manager at Unimicron Plant Technology.

The farming zone also serves educational reasons by enabling primary school kids to gain knowledge about environmental technologies and raise awareness, according to the Taipei Rapid Transit Corporation.
