So far, it 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.

At a cost of about USD 1 trillion, according to estimates from consultants KPMG, the plan is also crucial to Modi`s ambition of attracting investment while providing jobs for the million or more Indians who join the workforce every month.

His grand scheme, still a nebulous concept involving quality communications and infrastructure, is beginning to take shape outside Gandhinagar, capital of Gujarat, with the first "smart" city the government hopes will provide a model for India`s urban future.

Among the challenges to getting new cities built or existing cities transformed is the lack of experts who can make such huge projects work and attracting private finance.

To build smart cities, the NDA Government allocated 60 billion rupees (USD962 million) in its annual federal budget for the financial year starting April 1, even as it spent just a fraction of last year`s allocation of 70.6 billion rupees.

Gujarat International Finance Tec-City (GIFT), as the smart city is called, will double up as a financial hub, with tax and other breaks to lure banks, brokerages and other businesses.

Developed in partnership with IL&FS Engineering and Construction , it aims to compete with India`s own financial capital of Mumbai as well as overseas rivals like Dubai and Singapore.

Pressure on India`s existing urban centres is already intense, with cities like Mumbai gridlocked by traffic and hampered by poor infrastructure and a lack of amenities like parks and effective public transport.

India has built planned cities in the past, including Chandigarh, designed by French architect Le Corbusier, and Gandhinagar itself. But the scale of its current push is unprecedented.

A bird`s eye view from atop one of the two office buildings on the 886-acre GIFT site, a venture which began when Modi was chief minister of Gujarat, shows little sign yet of the 9 billion rupees spent on the first phase.

But the sandy plain hides infrastructure including an underground tunnel for utilities, a first in India.

The government has yet to decide what exactly will make a city "smart", but the programme is expected to include building new centres as well as adapting existing ones.

Existing cities like Dholera and Surat in Gujarat, and Visakhapatnam in the east, have already begun work to transform into smart cities with help from companies such as Microsoft Corp , IBM Corp and Cisco Systems .

Beyond GIFT, greenfield projects are likely to face hurdles including land acquisition rights and lengthy approval processes, as well as finding the right location.

GIFT has the advantage of being flanked by a river on one side and a national highway on the other, and also sits between Gujarat`s political capital of Gandhinagar and its business hub of Ahmedabad, with a large international airport.
