Smart move? India building 100 high-tech 'smart cities' to rival Dubai and Singapore
Ambitious proposal for 100 new urban centres to deal with population boom requires infrastructure overhaul and major private investment

India's push to accommodate a booming urban population and attract investment rests in large part with dozens of "smart" cities like the one being built on the dusty banks of the Sabarmati river in western India.
So far, the city boasts modern underground infrastructure, two office blocks and not much else.
The plan, however, is for a meticulously planned metropolis complete with gleaming towers, drinking water on tap, automated waste collection and a dedicated power supply - luxuries to many Indians.
With an urban population set to rise by more than 400 million people to 814 million by 2050, India faces the kind of mass urbanisation only seen before in China, and many of its biggest cities are already bursting at the seams.

Ahead of his election last May, Prime Minister Narendra Modi promised 100 so-called smart cities by 2022 to help meet the rush.
