Earlier this year, Juniper Research crowned Singapore as the world’s smartest city, using a range of factors including adoption of smart grid technologies, intelligent lighting, use of information technology to improve traffic flow, wi-fi access points, smartphone penetration and app availability. Barcelona, London, San Francisco and Oslo took the other top-five spots.
“Traditional smart city initiatives require lots of expensive sensors and a lot of data from different sources to create automation,” says Priya Prakash, founder of Design for Social Change, a London-based company that provides smart city technology solutions.
But the concept is being applied across the world, with many of the most ambitious smart city initiatives taking place in Asia.
For example, India’s prime minister Narendra Modi has launched a Smart Cities Mission to develop 100 smart cities over the next five years. India faces one of the biggest urbanisation challenges in the world, with only 30 per cent of the population currently living in cities, but some 300 million people – almost equivalent to the population of the United States – expected to arrive over the next 15 years.
“India is a great greenfield site to try out smart city initiatives,” says Ms Prakash. “It’s very interesting to see how countries are almost leapfrogging the developed world in terms of how they gather data. There is a big onus on using low-cost technologies that can be scaled up more quickly.”
The Smart Cities Mission is offering the successful cities a share of a £5-billion pot of government money, but they will have to raise further funds from the private sector. “Overall, £24 billion worth of investment is expected across 100 cities over the next five to seven years,” says Niraj Saraf, connected cities mission lead for Innovate UK, which has just taken a group of smart city entrepreneurs to India to coincide with prime minister Theresa May’s visit.
The purpose of the Smart Cities Mission is to drive economic growth and improve the quality of life of people by enabling local area development and harnessing technology, especially technology that leads to smart outcomes. According to the Indian government: “The objective is to promote cities that provide core infrastructure and give a decent quality of life to its citizens, a clean and sustainable environment and application of smart solutions.”
Shruti Chandra, manager of Invest India, adds: “The core elements of the programme are the provision of adequate water, electricity, sanitation, health, education and urban transport.” Other priorities include cutting air pollution, creating safer cities and improving governance.
Putting citizens first
However, because the bidding cities were in competition with each other, each one took a slightly different approach. “Because they were competing for funds, they really tried to create a unique identity that played to their strengths,” says Ms Prakash.
Even if Indian cities are setting out from a different starting point, Mr Saraf says, there is a very similar view on what a smart city is. “In a city with only two hours of mains water a day, an open data store isn’t really a priority. But, just as in the UK, there is a recognition that there must be a citizen-oriented approach. You have to engage people, not just push technological solutions,” he says. The most successful smart city initiatives focus on finding out residents’ priorities before anything else.
Richard Howells, chief executive of Bronze Labs, another company that accompanied Mrs May to India, says: “You need to take a bottom-up approach to create a smart city.” Bronze Labs focuses on increasing city resilience by sharing data and “connecting people to people, people to things and things to things” in emergency situations such as floods and other natural disasters. But this also has more prosaic applications such as telling people if their bus or train is going to be late, or reporting potholes to the local authority.
“It’s about accountability,” Mr Howells says. “If you can see something is being done, it makes you feel that you are involved in how your city is being run.”
The digital divide
One challenge for India’s cities is to overcome the digital divide. While in the West this issue is often seen in terms of the elderly missing out on the benefits of digital technology, “in India and China there are a lot of people at different levels of digital access”, Ms Prakash points out.
India is now the second-biggest market for smartphones in absolute terms, with more than 220 million subscribers, but as a proportion of the population this is still less than 30 per cent.
