Origin of compact city
The term compact city was 1st coined in 1973 by George Dantzig and Thomas L. satty
Two mathematician whose vision was largely driven by a desire to see more efficient use of resources.
Compact cities were created by the idea of sustainable urban planning in the European countries in late 1990,s.
The concept of compact city is based on sustainability, a term used by a club of Rome in 1972.
CHARACTERISTICS OF SUSTAINABLE CITY
Urban justice Urban beauty Creativity Ecology Easy to move and access Compact and polycentric diversity
THE TERM: COMPACT CITY
The compact city or city of short distance is and urban planning and urban design concept, which promotes relatively high residential density with mix land use.
Based on,
I. Efficient transport system and
II. Urban layout Encourages walking and cycling, low energy
consumption and reduce pollution. Social interaction and eye on the street
NEED OF COMPACT CITY
COMPACT CITY MODEL
General characteristics of compact city
Form of space High dense settlements Less dependence of
automobile Clear boundary from
surroundings Clear identity
Form of Function Social fairness Self-sufficiency of daily life
Other characteristics Urban infrastructure especially sewerage and water
mains. Multi nodal transportation High degree of accessibility local/regional. High degree of street connectivity including side
walk and bicycle lanes. Overlapping
POSITIVE IMPACTS OF COMPACT CITES
Environment
Less energy consumption Less GHG (green house gases)
consumption.
Preservation of land for agriculture and water resources.
Efficient use of energy.
Low electricity demand.
Economy Low travel cost Less congestion Higher mobility and higher
productivity More cost effective public
services provision e.g. road and water.
Maximize impact of public investment.
More frequent exchange of ideas which leads towards the innovation and wealth creation.
NEGITIVE IMPACTS OF COMPACT CITES
Lack of affordable housing’ Poor access to green spaces’ increased crime level Higher death rate due to respiratory
problems
CITIES FOLLOWING THE COMPACT CITY MODEL
Melbourne (AUSTRALIA) 31 municipalities 4 million population
Toyama (JAPAN) City of Toyama 0.4 million population
Vancouver (CANADA) Metro Vancouver 2.2 million
Curitiba (BRAZIL) Southern Brazil 2.3 million people 7th largest city in Brazil The smiling city
URBAN SPRAWL Urban sprawl means the spread of urban
areas into rural areas such as farmland, forests and coastal lands that lie on the outer edges of cities.
Urban sprawl is the unchecked spreading of a city or its suburbs.
It often involves the construction of residential and commercial buildings in rural areas or otherwise undeveloped land at the outskirts of a city.

Urban sprawl characteristics
Low residential density
(1 house= 1 family) Lack of public transportation Unlimited outward extension of
urban development Leapfrog development All transportation dominate by
privately owned motor vehicles
Impacts of urban sprawl
Economic Impacts of Urban Sprawl Urban Sprawl is not always checked
and systematic. This isn’t very helpful for the economy.
The auto dependent development causes a lot of disadvantages including inefficient street layouts, car dependency
Increased Infrastructure costs Living in larger, more spread out
spaces generally makes public services more expensive.
Taxes are risen (bad for the people good for the government).
Environmental impacts
Urban sprawl can cause automobile dependency.
Increased Pollution and reliance on fossil fuel
More carbon emission adds up in the atmosphere.
Urban sprawl may be partly responsible for the decline in social capital in the United States
Solutions and suggestion
Limit the sprawl
By doing this, the city can manage its expenses easily can also be more efficient during keeping track of
taxes. There will be good population control and more
room for open space and agriculture, which every
city requires.
Otherwise,
Limit the sprawl
Counter Solution
Not every city has to limit its urban sprawl. Natural will do it by own.
