The Title: Aquapolis 2020
NAME:Chao Wang CITY:South Tungchow City,China
As climate change,global warming of the ocean and the air will accelerate the melting of the ice sheets.The rise in sea level may well threaten our homeland,especially the cities close to the seaside.What these coastal cities will be?Will they just submerge and people who live in them leave thier home?Or will they accommodate the changes and utilize the new situation?Will we live above the sea instead of next to it?The project Aquapolis 2020 gives a vision of the city above the sea in the future.
In order to build resilience to the climate change, peak oil and also the increasing density,the Aquapolis establishes its urban systems around following principles:
Carbon Neutrality — To achieve carbon balance,on one hand,we reduce the carbon dependency of the city which most comes from buildings and transportation. On the other hand,we establish diverse urban green systems to impove the carbon absorbency.
Local Self-Sufficiency — We create more sustainable supplies of goods and services including food, power, freshwater and also R&D capacity both for the city and the region.
Systems Diversity — The diverse power generating systems which includes:
The Wind-power Generator
The Tidal-power Generator
The diverse water cycling systems which includes:
The Seawater Desalinization System
The Irrigation System
The Sewage Treatment System
The diverse food harvesting systems which includes:
The Urban Farmland System
The Vertical Farming System
System Hybrid — To increase the working efficiency of systems and reduce the energy lost during the operation,we intermix the interrelated systems together,combine them into a hybrid system.
High density&Mixed used — To accommodate the increasing population and to satisfy various demands whithin limited land,we plan the city in a extremely hign density and intensely mixed function.
WHERE WE (WILL) LIVE
The site locates in Lvsi,South Tungchow City,China which is in the west bank of Yellow Sea.Thousands years ago,the land was still beneath the wave.Today,the rise in sea level caused by global warming seems to push the city into ocean again .If we could not aviod all these happen, what could we do then?Do we have the only choice ,which is,we have to leave our homeland?
Besides,we still have to face the threats from peak oil.As a developing city.The consumption of petroleum is keeping growing.When the oil runs out,what else can we use to drive our machine in the near future?
In the meantime,the increasing density also troubles us.Due to rising seawater swallowing our land,we can not solve the overpopulated problem through the endless urban sprawl.And the food issue seems to be more urgent because of both the reducing farmland and increasing demands.
WHAT WE (WILL) HAVE
What do we have today?
Luckily,where we live is one of the best place to generate wind power.The average wind speed at the hight of 70 m comes up to 7 m/s.And as a result,we have the largest windmill plants in Asia.
Apart from this,we have rich resouces of tidal energy.The average tide range comes to 3.91m,and the extreme tide range comes to 5.95m.(The tide range higher than 3m could be used to generate electric power in theory)
Then what will we have tomorrow?
Plenty of seawater,of course.
The latest Urban Plan of South Tungchow City(2010-2030) represents a city in large scale,connected by extremely dense road network.But once the sea water sweeps,we'd have to build more and more dams and excavate more and more rivers so that the land is limited by the dams and the road network becomes river network.Will the plan still work in that time?
