To solve these difficult problems remaining for over 100 years, the neighbourhood should have sufficient public green spaces for humans and more than humans. Firstly the contaminated soil must be remediated. More trees and shrubs should be planted because the roots can absorb the pollutant elements and transform them into nutrition. The roots can also stabilize the soil and fertilize the soil. An urban forest can also effectively absorb carbon dioxide and nitrogen dioxide, improving the air condition.

 

Then we use urban agriculture as another proper strategy to activate the area. Usually, urban agriculture can be employed on vacant and derelict land. Residents can also be encouraged to participate in horticulture activities. Urban agriculture with ecological irrigation and cultivation can effectively transform vacant land into an active open green space. Urban agriculture can also activate economic activities with markets, bars and kitchens, providing more chances for people to do social activities. Besides, crops and fruits are also healthy food resource for urban wildlife.

​

After decades of development, the communities will be activated and connected by the two eco-agricultural parks. In the future, we expect that more trees and agricultural boxes will be planted in streets and private gardens. A cycling route, ecological network and food supplement network is expected to be formed in the next 50 years.
