Conurbations and metropolitan regions are urban agglomeration.
Metropolis and Mega city
Metropolis is essentially a large city. But the criteria of population to define a city as large varies from country to country.
|India||Greater than 1 million population is called Metropolis |
Greater than 10 million population is called as Mega city
|Canada||Greater than 5 million population is Mega city|
A related concept is that of megalopolis. It was used for the first time by Lewis Mundford while trying to classify cities on the basis of level of development and quality of life.
Megalopolis is an unusually large city that is almost bursting at it seams. It will have a problem of congestion, pollution, and consistent decline in the quality of life and erosion of economic base of the city.
The term was again used by Jean Gottman in his book Megalopolis. He was trying to describe the growth and expansion of modern urban city in the US as a consequence of expansion of motorway transport.
Unlike Mundford, who used the term in negative concept as a city in decline Gottman used the term more in a positive context referring to the growth and expansion of the city with better communication and economy. Gottman used the term Megalopping to refer to the process of rapid expansion of cities in America after the 1950s.
Eopolis --> Polis --> Metropolis ---(Congestion problem)---> Megalopolis ---(Failure in administration)---> Tyranopolis ---(Dead city)---> Necropolis
It is a continuous urbanization. It was used for the first time by Patrick Geddes in his book "Cities in evolution". Conurbations are extensive urbanized regions where many towns and many large cities have merged together along one major connectivity link.
Unlike a megalopolis or metropolis, which is centred around one large city, a conurbation has many cities with their extension and suburban expansions that have fused together. The merger is not physical merger alone. But it's more economic and social with the Conurbation having one single labour market.
With the development of connectivity, better roads, rapid mass transport systems, the economy of cities in Conurbation acts as one single economic entity.
Examples of Conurbation
- BosWash conurbation
- In USA
- It links Boston in the North with Washington DC along the Atlantic seaboard. It includes cities like New York, Philadelphia, Baltimore, etc.
- Golden horseshoe conurbation
- In Canada
- It includes the cities along the Southwestern edge of Ontario. it includes cities like Montreal, Toronto, Hamilton, Windsor, etc.
- This conurbation has 1/4th of the Canadas population
- Midland conurbation
- It includes all major cities in South Pennines
- Midland conurbation includes Birmingham, Coventry, Dudley, Derby, Wolverhampton, Sheffield, South-Hampton, etc.
- Taiheiyo conurbation
- Along the eastern coast of Honshu Island
- Tokyo, Yokohama, Osaka, Nagoya, Kyoto, Kobe.
- This conurbation has an 85 million population.
- One of the largest in the world
- The Yangtze and Pearl River Delta conurbation
- Along pacific coast
- Beijing, Tianjin, Shanghai, Guangzhou, Hong Kong, Macau.
- All the cities are Special Economic Zones. Shanghai is the largest.
Conurbations in India
India doesn't have any conurbation but I'm any highway corridor which have the potential to become conurbation
- Delhi Kolkata
- Delhi Agra Mathura Bhopal
- Delhi Jaipur Ahmedabad Mumbai
- Bangalore Mysore
- Mumbai Pune
- Vadodara Surat Mumbai Panjim Mangalore
It is a type of urban agglomeration. But unlike a metropolis, a megacity, a megalopolis, or a conurbation, it is not a continuous extensive area of urbanization. The Metropolitan region includes one major city along with its suburban extensions and also smaller towns, satellite city interspersed with rural areas, along with their agriculture-based land uses.
Unlike a conurbation, which is multi-centered with many cities fusing together and the cities maybe all of the same heirarchical level. In metropolitan regions there are many towns and cities but none compared to the main metropolis that holds the region together. The best example of such a city is Delhi NCR which includes suburbs like Gurgaon and Noida, satellite towns like Bulandshahar, Alwar, Bahadurgarh, Ballabgarh, Agra, and Mathura along with numerous villages and their agricultural land.
