The growth and suburbanisation of London was influenced by the development and expansion of the underground and over gound rail network.
In contrast suburbanisation in LEDW cities has been influenced by both migration and transport infrastructure.
The population of Greater Mumbai today is estimated to be around 23 million. This numerical growth has been, generated by in-migration from the districts of Maharashtra on one hand, and from neighbouring states on the other. Job opportunities in the expanding industries, financial institutions and administration have made the city attractive. Natural growth of the resident population is also accounting for an increasing proportion.
Insularity and the north-south linear configuration have necessitated a northward urban sprawl of the city from the south end, first into northern sections and later into Salsette and Trombay. The northward growth is still continuing unabated along the traffic corridors and in recent years augmented by an eastward march across the Thane Creek. Mumbai today is more a conurbation than a sharply defined `million' city.
The 1930s and 40s saw the rise of Shivaji Park area, Matunga and Mahim as the outlying suburbs.By the 1960s, the inner suburbs in southern Salsette and Chembur-Trombay had emerged. The 70s and 80s saw the assimilation of the `extended suburbs' beyond Vile-Parle and Ghatkopar.
The northern fringes of Salsette beyond the municipal limits have been sucked into the suburbanisation process in the last decade. Conceived as a counter-magnet to Mumbai, Thane, Vashi and Belapur have emerged merely as extended suburbs.
In this process of suburbanisation, a spatial order of succession (step by step growth) is evident. The northward creep along the rail-cum-road corridors, crystallising into dormitories around the rail head is the first phase. The west side in each case is invariably developed first. The building of the Express Highways has brought a subsequent east side development. Built up areas extending outwards, away from the rail head is the next phase. Such extensions progressively spread over new reclamations on the creekside, and an upward creep on the hill slopes and levelled sites towards the central hill complex of Salsette. With the rail head as the focal point of commuter convergence, roads leading to the rail head have become shopping fronts. While the reclamation grounds house middle and upper class society, inevitably accompanied by hutments in the niches, the lower hill slopes of the central hill zone shelter innumerable shanties.
The dormitory character of early suburban development has undergone vast transformation following family in-migration. The cosmopolitan character of early Mumbai that was an urban mixture of groups of in-migrants living in closed communities has itself changed as the suburbs have matured into an urban amalgam of people of varied linguistic, religious, caste groups that are stratified more on economic grounds.
Today, less than a third of the population of Mumbai lives in the `island' city. Nearly half lives beyond Vile Parle in the west and Old Kurla in the east. The centre of density of population has shifted from the island city well into suburban Salsette. With the `suburban' Mumbai growing faster than the island city, especially in its northern parts, the centre of density is bound to move further north in the immediate future.
The commuter traffic is no more one way into the Central Business District (CBD) in the south of the city in the mornings. Though it is still the main movement, movement in opposite direction is substantial and is gaining in strength, thanks to industrial jobs in the suburbs. East-west cross flows within the suburbs and beyond, into and out of Vashi and further outwards are also increasing. It is therefore not surprising that two-thirds of the BEST bus service is now focussed on the suburbs of Salsette, Trombay and beyond.Real estate is more active in the distant suburbs than in the city. Urban renewal is no more confined to the city. South Mumbai colleges and schools are concerned about falling numbers of students. Few of the residents of the suburbs today seek the markets and shopping arcades of South Mumbai or Dadar. The suburbs have become increasingly self-supporting, in terms of their needs of shopping, education and medical amenities and entertainment. Only civic amenities and infrastructure lag behind. The suburbs are no more suburbs. They have come of age, and have distinct identities as organs of the larger urban mosaic.
