The city of Bangalore grew from about 5.7 million people in 2001 to 8.7 million in 2011. Earlier, the official city area was 226 square kilometres under the erstwhile Bangalore Mahanagara Palike (BMP) which expanded to 716 square kilometres in 2007 with the creation of Bruhat Bangalore Mahanagara Palike.
However, these area numbers only reflect the official administrative boundaries, and are not always reflective of the organic growth of cities in various directions. Below are two land use images from ISRO’s Bhuvan portal of Bangalore from 2005-06 and 2011-12. Built-up area in the region is marked in red.
In the period of five years, Bangalore has grown in area mostly only on the southeastern side. It has grown considerably along Hosur road, forming a continuum between the city, spanning Electronics City until the edge of the state boundary. The bulk of the rest of the growth has happened along the southeastern section of the outer ring road.
We can rail against ‘unplanned’ growth all we want, but this misses the point that people and companies are essentially free agents who move to places conducive to their requirements. Urban planning in India often centers around rigid control in things like land use, where the state has little capacity to enforce anything, and gets subverted. If instead urban planning favours nudges and incentives (the setting up of electronic city in Bangalore in the late ’70s is a great examples of the latter) then it might have a better chance of working. Official actions are largely unresponsive to the housing needs of incoming migrants and increasing wealth of our cities’ residents. “Irregular” colonies and housing but spring to meet the legitimate need.
Besides, as Karthik Shashidhar finds, Bangalore’s fastest population growth rates were actually in the 1940s and 1970s.
