8 story edible green wall + Shanghai's green roof incentive program

For years the talk has been that "vertical farming is ten years away at least". But we see perhaps a giant leap forward as an organization in Barcelona, Spain has created an 8 story vertical green wall garden.
It is indeed the first of its kind, featuring moveable planters which one can take care of by hand plus a neat little elevator to bring supplies up and down. Making the garden accessible via stairs is cost prohibitive and cannot be replicated on a wide scale, but I don't think anyone can argue that this project ushers in a new vertical gardening era.

-Shanghai, China has announced the second (after Singapore) green roof AND green wall incentive program. Truth be told, there won't be many 1,000 square meter (11,000 square feet) green walls, but there will be no complaints from folks who install big green roofs.
