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.

Thomas Ledwell is director of communications, and Adam Cutts research coordinator, at NewCities.

A voice for the city: how should mayors respond to terror attacks?

When Andy Burnham, a former British government minister, won the election to be Greater Manchester’s Metro Mayor recently he was probably focused on plans for the region’s transport, policing and housing – and, of course, all the behind the scenes political work that goes on when a new role is created. The Conversation

And yet just a few weeks after taking on the role, terrorism has proved to be his first major challenge. Following the horrific bomb attack following a concert at one of Manchester’s most popular venues, he quickly has had to rise to the challenge.

It is a sad fact of life that as a senior politician, you will soon have to face – and deal with – a shocking incident of this kind.

These incidents arrive regardless of your long term plans and whatever you are doing. Gordon Brown’s early tenure as UK prime minister, for example, saw the Glasgow terror incident – which involved an attempted car bombing of the city’s airport in June 2007. Just four days into his premiership, Brown was dealing with the worst terrorist incident in Britain since the attacks on London in July 2005. Andy Burnham now finds himself in a similar situation.


Giving Manchester a voice

For Burnham, as the mayor and messenger of Manchester, an attack of this scale needs a response at several levels.

There is the immediately practical – dealing with casualties. There is the short term logistical – dealing with things like transport and closures. And there is the investigation and (hopefully) prevention of any follow ups.

But he will also need a “voice”. People look to particular figures to give a voice to their outrage, to talk about the need for calm, to provide reassurance, and to offer unity and express the sadness overwhelming many.

Part of the thinking behind the UK government’s enthusiasm for elected mayors was a perceived need to provide strong, local leaders. And a strong, local leader’s voice is exactly what is needed in Manchester now.

There is a certain choreography to the response to these events. It tends to go: a brief initial reaction, a visit to the scene, then a longer statement or speech. This is then usually followed by a press conference and interviews, along with visits to those affected. I say this not to be callous, but to highlight the huge demand the news media places on leading political figures when tragedy strikes.

‘We are strong’

As expected, Burnham made a speech on the morning after the attack. It is probably better described as a statement, in that it was short and to the point. But despite its brevity, in nine paragraphs, he summed up just about every possible line of thought.

The speech covered evil, the shared grieving and the need for the city to carry on. He also praised the work of the emergency services, and highlighted the need for unity and the very human reaction of the local people who provided help to those affected.

Burnham now has the task of bringing people together while there is still doubt about many aspects of what happened. A vigil in the centre of Manchester was rapidly planned for Tuesday evening, and there will be many other potential initiatives to follow.

Incidents like this tend to leave a large and long-lasting footprint. The effects of the bomb will last for years, whether in concrete reality or in people’s awareness and memories. And Burnham must now lead the effort to ensure Manchester emerges from this shocking incident with cohesion and strength.
