The Centre is all set to commit Rs 50,000 crore over the next five years for improving and modernising the urban infrastructure all over the country. A total of 60 cities have been identified for upgradation, comprising seven mega cities of Delhi, Greater Mumbai, Ahmedabad, Bangalore, Chennai, Kolkata and Hyderabad, 29 cities with million plus population and 24 other cities with less than one million population. The major initiative at urban renewal has emanated from the Prime Minister's Office in view of the fact that while the population has grown three times since Independence, urban population has grown five times.
