Too dependent on mega cities, we need fresh perspectives to urban growth! May 17, 2012
That the world is urbanizing rapidly is by now something we all understand. The implications of this massive shift in how humans live is still a subject of intense scrutiny and research among urban professionals, sociologists, geographers, demographers, economists and experts from a growing number of fields hitherto unrelated to spatial planning.
Delhi at No 4! An intriguing phenomenon of urbanization has been the formation of urban agglomerations, large urban areas that grow around a nuclear urban core and create a dense economic powerhouse that in turn attracts more businesses and people to it. In the latest edition of the Demographia World Urban Areas finds our own Delhi (along with its urban extensions in Haryana and UP) as the world’s 4th largest urban area, behind Tokya, Jakarta and Seoul. The cities considered big when we were growing up feature further down the list. New York comes in 7th. London, which ranked 3rd till the 1960s is not even in the largest 25 urban areas! Asian cities take center stage, followed by cities in South America and Africa. Within India, Mumbai (13th) and Kolkata (18th), usually considered larger urban concentrations that Delhi lag behind. Those in the real estate industry, who have been tracking closely the growing economic power of the Delhi National Capital Region, would perhaps not be so surprised as the rest of us.
The subcontinent is exploding! From a density perspective though, Mumbai, Surat, Ahmedabad and Jaipur are Indian cities that feature in the list of the ten densest cities in the world! Seven of these ten are in the South Asian subcontinent (add Dhaka, which tops the list, Chittagong and Karachi)! To me, these statistics have driven home the need for much more urgent responses to our urban issues. And since the problems are going to stay, we need long-term, sustainable solutions, not stop gap ones.
Fresh ideas please! To me, it also makes me worry that we are overdependent on urban agglomerations and mega cities. It shows a terrible lack of imagination on the part of policy makers and planners to be unable to give impetus to smaller towns and create new urban areas that offer economic opportunities and offer quality of life to residents at the same time. These might stand a better chance at building a sustainable foundation (environmentally and socially) than the mega cities, where interventions are expensive and hard to implement!
