In China, they have a national forest city scheme and they now certify cities as national forest cities.

The reason (China is) are doing that is really to attract business, to attract conferences, to attract tourists, to attract companies to come in.

I think a good case in point is Seoul, in South Korea -- they actually took out an entire motorway (in the city center) and put the river in there with trees and plants, in Manila, they are establishing miniature parks wherever they can -- crossroads, along the railway, old industrial areas -- there's a lot of urban space that is wasteland, so there are areas that can be converted.

Some is about managing existing tree stocks but some of it is about planning for the future. The green things shouldn't be what's just left over. It's a vital part of the city and it's at risk of being lost. for some cities, in a way, there's not enough space left, so going vertical might be a solution.
