| people create green infrastructure |
| Urban Ecosystem Services |
| cleaner water | |
| less stormwater & flooding | |
| cleaner air | |
| carbon exchange | |
| reduce heat island effect | |
| prevent soil erosion | |
| better human habitat | |
| Ecosystem Services |
| better wildlife habitat (including birds) |
| Urban Vegetation Challenges |
| bad air | |
| not enough water | |
| bad soils | |
| few nutrients | |
| not enough canopy space | |
| not enough root space | |
| insects & diseases | |
| people donŐt care |
| Good City Trees? gingko & ? |
| green infrastructure = natural systems |
| planned by people | |
| managed well & often | |
| over large spaces |

| Green Roof (ASLA, Washington D.C.) |
| Tokyo Metropolitan Assembly Hall |
| Ecos, Sept-Oct 2004 |
| Why? |
| problem! urban heat island effect | ||
| last 100 years - Tokyo warming 5 times faster than other places | ||
| 5.2 degrees since 1990 | ||
| 14% Tokyo covered by greenery | ||
| roof garden good solution | ||
| new regulation, mid-sized buildings, 20% of roof to be garden | ||

| Community Gardens |
| ecosystem services | |
| urban agriculture = food | |
| build community |
| Community Gardens as Parks |
| good food & good design |

| Arboriculture |
| art & science of tree care |
|
| trees provide many ecosystem services |
| Prevent Hazards & Damage |
| healthy trees are safer trees |
| Challenge: Compact Spaces |
| root & canopy zones |
| Challenge: Severe Pruning |
| weakens branches | |
| shortens life of tree | |
| reduced ecosystem services |
| City Trees Growth |
| U.S./ Europe cities |
|
| Japan cities? |
| if no topping or severe
pruning . . . alternatives for Japan cities? |
