Shanghai Mega City
Transcript of Shanghai Mega City
Recently the number of cars in Shanghai has shot up. In the 1980's there were only about
100,000 cars, by 2004 there were 2 million
In the last 2 years private car ownership has doubled
From the years 1996 to 2006 there was a 400% increase in car ownership
In the last 10 years there has been 1,500 miles of roads created in or right around the city
As the GDP in Shanghai rose the number of people who wanted and bought cars increased
The large increase in cars has lead to an astounding increase in oil consumption. China's
energy demand is growing at a rate of four times the global rate.
Every year there are about 250,000 being added to the city's car fleet.
One problem that is causing increased traffic is the lack of public parking spots. On any
average day in the city there are 1.2 million cars downtown. Right now there are only 780,000
public parking spots.
Mega City Shanghai
Information About Shanghai
Information About Shanghai
This is a picture of a pollution cloud covering Shanghai.
The smog is Shanghai has been a constant problem for the
past few years. Unlike the USA, Shanghai has quite a lot of days
every year that can't be classified as blue sky days due to the
Established 700 years ago
Located at tip of Changjiang River Delta
on the East China Sea, that is why it is
called "On the Sea"
Industry is based on machinery
manufacturing, textiles and steel.
City Flower= White Magnolia
It is a low coastal city in China.
It is in the east coast halfway between
Beijing and Hong Kong.
Population as of 2011 is 23.47 million
The Story of Jin
Jin moved into her house as a teen in 1937
Jin is now a 91 year old, and she still lives in the
same house. There has been a change though.
Instead of one family leaving in the two story house
there are now eight. Each family has one room to
live in. This is just one of many examples of the
overcrowding that is taking place in Shanghai.
Facts About Overcrowding
In the last 15 years the population has increased
from 13.5 million to 21.5 million
In Shanghai there are 4 times as many people living in
a square kilometer than in New York City
There has already been many communities built outside of the city to try to relieve the overcrowding, but it isn't enough.
From 2000 to 2004 the population almost increased
4 million people, that is about a population increase
of 1 million a year!
According to UN, a city must have at least 10 million people and at least 2,000 people per square kilometer to be considered a mega city
To put more people or things into an area than it is comfortably able to hold
The excessive movement of vehicles, persons, etc in an area, along, a street, through an air land or over a water route.
The harmful or poisonous substances introduced into an environment
In 2004 Shanghai reached 2 million cars.
There have been huge road expansions. "Just one year after some roads were completed, they reached vehicle flow volumes that were projected for 15 to 20 years from now," said Yang Dongyuan. Dongyuan who is a professor at the School of Transportation Engineering.
How will Shanghai deal with this blooming population? Can more people be squeezed into this city or is there a way to fix this problem?
Shanghai has a huge reliance on coal. Coal is used in
industries and homes
Waters are rising in Shanghai likely due to pollution. It is
expected for the water to rise 60 mm by 2050 which will leave
low lying coastal city at risk.
Shanghai has serious water problems. Everyday 4 million cubic
meters of untreated waste are poured into the Huangpo River.
The rising numbers of cars has caused the pollution problem
to get even worse.
Shanghai has a lot of smog and sometimes pollution
clouds form above the city.
Shanghai's air quality rates from last year reached the fair rate
which is the middle tier for air quality rates. Fair is not good
enough and it is far off from the goal
The average coal plant produce 3,700,000 tons of carbon dioxide.
Coal also releases sulfur dioxide, which causes acid rain, and
nitrogen oxide, which causes smog.
Yu also lives in Shanghai. He lives 7 miles from his work place. In the morning he drops his son and wife, a teacher, off at school before going to work. The commute takes an entire hour, but that doesn't stop Yu. ""A new subway line will be completed to my neighborhood later this year, and I'm hoping many other people will ride it so that the traffic will get better," Yu said. "I'll keep driving my car, though. It's more comfortable because I can listen to music, use the air conditioner, and it's not crowded." "In China, everybody wants to have a car, and I'm just one of them," he said. Yu is right everyone in China wants the freedom and luxury of owning a car. Yu like many others would rather deal with the heavy traffic and huge expenses then to take a
convient train or subway. The city needs a way to get people to see that the subway and other
public transportations are neccessary for the city and will help with both the pollution and
the traffic problems.
The population of Shanghai
is almost the same as Australia.
The huge difference is the amount of
space the people live in.
There needs to be an increase in public transportation: More bus routes and more subways. Right now there is only 12 subway routes. With more routes, there will be less cars on the street, resulting in less traffic.
Bus prices should be lowered. Right now there are not regulated by the government, so companies can charge as much as they would like. With lower prices, more people will be able to afford the bus
Everyone in China Wants the Freedom of a Car
Shanghai already has about 4,000
sky rises. Even with all these
buildings there is still overcrowding.
The question is...has Shanghai
reached it's limit or is there a way
to relieve the overcrowding?
This chart shows how serious pollution has become in China. It is the worst in the big cities. However, all parts of China struggle with pollution.
This is an image of the population of
the world's mega cities in the past
and in the future.
Solar panels for electricity
Wind turbines will cut down the amount of carbon used
Place wind turbines in surrounding waters that are unused
Fuel cells to make heat, electricity, and hot water. All of the energy is recycled
The straddle bus is being created. It is a bus that travels above ground to transport people from one destination to another. There are 2 levels for people to sit and/or stand and it can carry 1200-1400 people. It is powered by electricity and solar energy, making it safe for the environment. It is said to reduce traffic jams by 20-30%
There is no where left for Shanghai to develop
They can use smart growth to build up, but eventually there will be no more room
Companies can move outside the city to areas with less of a population
Neighboring cities can try to develop faster with the help of Shanghai so people can spread out into familiar territory
People can begin to work from home
Use video conferences to communicate with business associates
People can live and work in the same building
With less business buildings, people can spread out
All of this can lead to less people having to use transportation to move around
China has a lot of different geographical areas. Many of these areas like the desert aren't nice to live in. Much of the Chinese population is on the east, especially the East coast where there is a great access to water. The below shows how the east coast is very populated. Along the coast there are tons of red and dark orange dots signaling a large population. The farther you get from the coast the lighter the colors get.
What more can China and Shanghai do
to slow down the population growth? Is there
anything more serious than limiting the number of
kids you can have?
If supermarkets, pharmacies, and other necessary stores are built in a close proximity to areas with large families, less people will need to travel far
Tougher immigration laws need to be put into place
This will make it harder for people to come and live in Shanghai
With less people coming into the city, the population and overcrowding might decrease
Shanghai has become a hazardous place to live
Second biggest greenhouse gas emitter
Poor air and water quality due to car pollution and coal combustion
So much CO2 and fossil fuel that a dark, polluted cloud have covered Shanghai
To clean coal a company could use pre-combustion and post-combustion
Pre-combustion: Crush coal and the impurities would be removed, about 30% of pollutants. Used before coal is emitted.
Post-combustion: removes over 90% of sulfer dioxide emissions from coal combustion. Used while coal is emitted.
To increase the amount of clean water, Shanghai can use the reed-bed system
This system is cost-effective and environmentally friendly
Treating sewage through small treatment works
Ways everyone can reduce the carbon output
