NEW DELHI: Prime Minister Narendra Modi today kickstarted three urban rejuvenation missions--smart cities mission, housing for all by 2022 and the Atal Mission for Rejuvenation and Urban Transformation."40% of our population stays in cities. How can they get better quality of life at a time when everyone is looking at India," asked Modi at a gathering of mayors and heads of urban local bodies from around 500 Indian cities."We cannot leave our poor to their fate. It is our responsibility," he said.Modi pointed out the it would have been good if we have recognised urbanisation as an opportunity 25 years back. "But better late than never."On the Housing for All scheme, he said that every person has a dream to own a house and that gives him further opportunity to dream.The scheme envisages to build 2 crore homes for the urban poor.He said that while private developers know which direction a city will grow and accordingly build homes, what is usually missing is the infrastructure that is key for living."Unless the city leadership does not know how the city will grow, it will not work. Through AMRUT , we will plan," he said.Development, he said, cannot be such that it becomes a tussle between cities and villages.On smart cities, he said that the decisions will be tsken by the leadership of the city, its people and by the urban local bodies. "It will be a ground up approach."The country will now look for innovative ways for financing these schemes and also public private partnership to implement them, he said.The Union Cabinet had approved spending of Rs 1 lakh crore for the Smart Cities Mission and the Atal Mission for Rejuvenation and Urban Transformation of 500 cities (AMRUT)The smart cities will be selected through a ‘City Challenge Competition’, and each city will get Central funding of Rs 100 crore a year for five years.
