Across the world, the accelerating wave of urbanisation is contributing to greater, more complex challenges for cities that require an urgent response.

Air pollution, to take one example, is choking cities and citizens, a growing problem across the developing world and in burgeoning cities in developed nations. The World Health Organization warns pollution is causing millions of premature deaths, urging action including more green spaces in cities.

One innovative startup in Berlin, GreenCity Solutions, has built a revolutionary urban air filter – The City Tree – combining air purifying, specialized-moss cultures and the latest in Internet of Things (IoT) technology. The storey-high, free standing and largely self-sustaining CityTree packs the air filtration power of 275 trees into a tiny fraction of the space and maintenance cost.

In cities around the globe, startups and social enterprises are developing inventive, technology-driven solutions to tackling urban challenges. GreenCity Solutions is one of these game-changing companies, and has been recognized as a Global Urban Innovator by the NewCities Foundation, an international nonprofit dedicated to making cities connected, inclusive, healthy and vibrant.

The Global Urban Innovators program is designed to recognse innovative young companies that are reimagining new solutions from the ground up – and in effect, shaping the cities of tomorrow.

The 2017 Class of Global Urban Innovators, announced on 2 May, is global in scope and features technological solutions and products that are leveraging IoT, artificial intelligence, and cutting-edge data production and analysis to improve everyday life for residents of cities and enhance the life of the city itself.

The innovations that enhance the human experience range from Green City Solutions’ clean air creating technology to Safetipin, a mobile app created in the Indian city of Gurgaon,  that crowdsources and relays public security information. Safetipin recently completed a street safety audit for New Delhi, including data from over 60,000 users, while at the same time offering digital tools for ensuring a safe trip home for women across the city.

Others improve our experience traveling in cities, such as Songdo-based Alt-A, a sensor technology and data-crunching effort to make the streets safer through alert systems, and 3D-mapping analytics of vehicle-human traffic flows. In San Francisco, Spin is reimagining bikesharing with a fleet of GPS-equipped smart bikes that are unlocked using a mobile app and can be dropped off at any bike parking spot.

Cape Town-based WhereIsMyTransport, an open platform providing a detailed look at formal and informal public transport options in African cities, both improves experience for users and provide emerging cities with crucial transportation data for better planning.

“We believe in the potential of reliable and openly available public transport data to empower and transform emerging cities,” says Devin de Vries, co-founder of WhereIsMyTransport. “Our technological solutions make this possible.”


Meanwhile, innovators are also leveraging technology to tackle problems that affect the life of the city itself, at operations level, street level and delivery of services. Where cities everywhere continue to struggle with effective public consultation, ZenCity, in Tel Aviv, is showing how Artificial Intelligence can unlock new opportunities for digital engagement, capturing residents’ perceptions of the city across social media, the web and traditional channels such as 311 calls. 

And Small Change is creating large changes in the way Pittsburgh connects much needed finance for high-impact neighborhood urban development projects through equity crowdfunding.

IoT technology is also creating opportunities to reimagine how cities deliver their most essential services. Paris-based CityTaps partners with city utility companies and, through smart water meters and mobile money, is making the case for equitably delivering urban utilities. 

“Our vision is to bring running water to every urban home in the developing world,” says Grégoire Landel, CEO of CityTaps. “With access to water, public health is greatly improved while saving time and money for the urban poor.” 

In cities around the world, urban innovators are seizing the potential of emerging technologies, as well as the need to collaborate with those driving innovation. The Global Urban Innovators count among the most promising and most advanced projects anywhere. 

These forward-thinking entrepreneurs will take the stage at the NewCities Summit – the NewCities flagship event – in Incheon Songdo, South Korea from 7-9 June, where a global community of experts will delve into the new realities facing today’s cities with a focus on the theme Thriving Cities: The Building Blocks of Urban Wellbeing

The wider implications of the disruptive use of technology bring to the forefront this urban era’s most important questions and, possibly, some innovative answers. Exploring these questions and their impact on the city through the eyes of today’s innovators themselves will be crucial for building urban well-being in the years and decades to come.

Budget 2017: Philip Hammond just showed that rejecting metro mayors was a terrible, terrible error

Sorry, Leeds, nothing here for you: Philip Hammond and his big red box. Image: Getty.

There were some in England’s cities, one sensed, who breathed a sigh of relief when George Osborne left the Treasury. Not only was he the architect of austerity, a policy which had seen council budgets slashed as never before: he’d also refused to countenance any serious devolution to city regions that refused to have a mayor, an innovation that several remained dead-set against.

So his political demise after the Brexit referendum was seen, in some quarters, as A Good Thing for devolution. The new regime, it was hoped, would be amenable to a variety of governance structures more sensitive to particular local needs.

Well, that theory just went out of the window. In his Budget statement today, in between producing some of the worst growth forecasts that anyone can remember and failing to solve the housing crisis, chancellor Philip Hammond outlined some of the things he was planning for Britain’s cities.

And, intentionally or otherwise, he made it very clear that it was those areas which had accepted Osborne’s terms which were going to win out. 

The big new announcement was a £1.7bn “Transforming Cities Fund”, which will

“target projects which drive productivity by improving connectivity, reducing congestion and utilising new mobility services and technology”.

To translate this into English, this is cash for better public transport.

And half of this money will go straight to the six city regions which last May elected their first metro mayor elections. The money is being allocated on a per capita basis which, in descending order of generosity, means:

  • £250m to West Midlands
  • £243 to Greater Manchester
  • £134 to Liverpool City Region
  • £80m to West of England
  • £74m to Cambridgeshire &d Peterborough
  • £59m to Tees Valley

That’s £840m accounted for. The rest will be available to other cities – but the difference is, they’ll have to bid for it.

So the Tees Valley, which accepted Osborne’s terms, will automatically get a chunk of cash to improve their transport system. Leeds, which didn’t, still has to go begging.

One city which doesn’t have to go begging is Newcastle. Hammond promised to replace the 40 year old trains on the Tyne & Wear metro at a cost of £337m. In what may or may not be a coincidence, he also confirmed a new devolution deal with the “North of Tyne” region (Newcastle, North Tyne, Northumberland). This is a faintly ridiculous geography for such a deal, since it excludes Sunderland and, worse, Gateshead, which is, to most intents and purposes, simply the southern bit of Newcastle. But it’s a start, and will bring £600m more investment to the region. A new mayor will be elected in 2018.

Hammond’s speech contained other goodies for cites too, of course. Here’s a quick rundown:

  • £123m for the regeneration of the Redcar Steelworks site: that looks like a sop to Ben Houchen, the Tory who unexpectedly won the Tees Valley mayoral election last May;
  • A second devolution deal for the West Midlands: tat includes more money for skills and housing (though the sums are dwarfed by the aforementioned transport money);
  • A new local industrial strategy for Greater Manchester, as well as exploring “options for the future beyond the Fund, including land value capture”;
  • £300m for rail improvements tied into HS2, which “will enable faster services between Liverpool and Manchester, Sheffeld, Leeds and York, as well as to Leicester and other places in the East Midlands and London”.

Hammond also made a few promises to cities beyond England: opening negotiations for a Belfast City Deal, and pointing to progress on city deals in Dundee and Stirling.


A city that doesn’t get any big promises out of this budget is – atypically – London. Hammond promised to “continue to work with TfL on the funding and financing of Crossrail 2”, but that’s a long way from promising to pay for it. He did mention plans to pilot 100 per cent business rate retention in the capital next year, however – which, given the value of property in London, is potentially quite a big deal.

So at least that’s something. And London, as has often been noted, has done very well for itself in most budgets down the year.

Many of the other big regional cities haven’t. Yet Leeds, Sheffield, Nottingham and Derby were all notable for their absence, both from Hammond’s speech and from the Treasury documents accompanying it.

And not one of them has a devolution deal or a metro mayor.

(If you came here looking for my thoughts on the housing element of the budget speech, then you can find them over at the New Statesman. Short version: oh, god.)
