The Green Potato

Tokyo, Japan

Picture 4 of 7

In The Green Potato Project launched by two subsidiaries of Japanese telecommunications giant NTT Corp., city farmers not only help cool down Tokyo but also harvest sweet potatoes in autumn. Sweet potatoes grow strongly in the tough roof- top environment of harsh sun and strong wind. The plants are particularly good for roof- tops because their wide leaves can cover the whole surface and are efficient at transpiration — evaporating water — which has a cooling effect The temperature of a roof area not covered by potato leaves was as much as 27 degrees Celsius hotter than an area covered by the leaves, according to a survey taken on top of the NTT Facilities building.
