The future of India's urbanization

In 2050, urban India will be home to fourteen per cent of the world's urban population. In less than thirty years, half of India's population will have to cope with urban life and there will be tremendous transformation of landscape, economic structure and social life. In order to forecast India's urban future, we assumed that secular and contemporary growth trajectories of all individual urban agglomerations are key drivers of future urbanization trends. We demonstrate that India's city-system conforms to the distributed growth model and that its hierarchical distribution is evolving regularly. India's plurisecular city-system fits well with the canonical model that describes universally the system dynamics. It shares common characteristics with several mature urban structures around the world. We show also that the location of the town has little influence on its growth trajectory. Nevertheless, individual trajectories can be classified, either by the secular trend of towns (1901-2011) or on the basis of the more recent genesis of the contemporary urban agglomerations landscape (1961-2011). These classifications are structured over time and space according to subsystems and regional specificities.
