Who needs time travel when you have enterprise?

The economy is back to where it was in 2006 - where do we go from here?

It’s strange to be waking up in summer 2012 to find ourselves in an economy that is no bigger than it was in 2006. So how can we travel "back to the future" and get the economy back on track? In the absence of a plutonium-powered car, the vehicle to get us back to economic growth is enterprise.

Centre for Cities’ new report, "Open for Business", shows how important enterprise is to a city economy. The research, sponsored by ICAEW, takes a detailed look at the make-up of city economies to establish what makes a city economically successful.

It finds there are two prongs to private sector economic growth in our cities – the ability to attract businesses from elsewhere (other UK cities and abroad) and the ability to "grow your own’. Our strongest cities are those that have been able to do both.

A detailed breakdown of the business bases of UK cities reinforces this point. The majority of the UK’s strongest cities are those that have a large proportion of branch businesses and high levels of enterprise:

Of course, being open to external business also means that in the short term some cities may be even more exposed to turbulence in the global economy. The Eurozone crisis may impact upon businesses headquartered in the Eurozone, potentially leading to consolidation of businesses and knock-on job losses. Cities like Coventry and Swindon, with a higher proportion of Eurozone-owned businesses, will need to focus on policies that can support domestic enterprise to help offset any potential fallout from troubles across the Channel.

Overall it is clear from the research that cities with a mix of home grown businesses and branches are best placed to weather any storms heading our way. But what does this mean for policy?

There has been no shortage of enterprise initiatives from previous Governments, ranging from Thatcher's Enterprise Allowance Scheme to New Labour's Local Enterprise Growth Initiative. The recently launched Start-up Loans are the latest addition to the list. But the impact that these schemes have had upon levels of enterprise is difficult to quantify based on existing evidence. So what can the government and cities do to hit the accelerate button on enterprise at a time of economic instability?

One thing that can make an important difference is for national government and cities to continue investing in the core themes that make a big difference to business. This means improving transport and skills and making the planning process more responsive to business needs.

Cities also need to respond to the specific challenges facing their local economies. Our work shows that open, entrepreneurial cities are best placed to grow, and cities should aim for this mix of home-grown business and receptive to new ideas and people.

Depending on the city’s specialisms and where it needs to improve, this could mean implementing policies from support for start-ups or existing companies to ensuring the city is working with UKTI and others to showcase where there are opportunities for external investment.

It will take time to get back to where our economy should be. But by getting enterprise policy right today, cities can help to steer the wider UK out of economic underperformance and into growth.

The deafening killer - why noise will be the next great pollution scandal

A growing body of evidence shows that noise can have serious health impacts too. 

Our cities are being poisoned by a toxin that surrounds us day and night. It eats away at our brains, hurts our hearts, clutches at our sleep, and gnaws at the quality of our daily lives.

Hardly a silent killer, it gets short shrift compared to the well-publicised terrors of air pollution and sugars food. It is the dull, thumping, stultifying drum-beat of perpetual noise.

The score that accompanies city life is brutal and constant. It disrupts the everyday: The coffee break ruined by the screech of a line of double decker buses braking at the lights. The lawyer’s conference call broken by drilling as she makes her way to the office. The writer’s struggle to find a quiet corner to pen his latest article.

For city-dwellers, it’s all-consuming and impossible to avoid. Construction, traffic, the whirring of machinery, the neighbour’s stereo. Even at home, the beeps and buzzes made by washing machines, fridges, and phones all serve to distract and unsettle.

But the never-ending noisiness of city life is far more than a problem of aesthetics. A growing body of evidence shows that noise can have serious health impacts too. Recent studies have linked noise pollution to hearing loss, sleep deprivation, hypertension, heart disease, brain development, and even increased risk of dementia.

One research team compared families living on different stories of the same building in Manhattan to isolate the impact of noise on health and education. They found children in lower, noisier floors were worse at reading than their higher-up peers, an effect that was most pronounced for children who had lived in the building for longest.

Those studies have been replicated for the impact of aircraft noise with similar results. Not only does noise cause higher blood pressure and worsens quality of sleep, it also stymies pupils trying to concentrate in class.

As with many forms of pollution, the poorest are typically the hardest hit. The worst-off in any city often live by busy roads in poorly-insulated houses or flats, cheek by jowl with packed-in neighbours.

The US Department of Transport recently mapped road and aircraft noise across the United States. Predictably, the loudest areas overlapped with some of the country’s most deprived. Those included the south side of Atlanta and the lowest-income areas of LA and Seattle.

Yet as noise pollution grows in line with road and air traffic and rising urban density, public policy has turned a blind eye.

Council noise response services, formally a 24-hour defence against neighbourly disputes, have fallen victim to local government cuts. Decisions on airport expansion and road development pay scant regard to their audible impact. Political platforms remain silent on the loudest poison.

This is odd at a time when we have never had more tools at our disposal to deal with the issue. Electric Vehicles are practically noise-less, yet noise rarely features in the arguments for their adoption. Just replacing today’s bus fleet would transform city centres; doing the same for taxis and trucks would amount to a revolution.

Vehicles are just the start. Millions were spent on a programme of “Warm Homes”; what about “Quiet Homes”? How did we value the noise impact in the decision to build a third runway at Heathrow, and how do we compensate people now that it’s going ahead?

Construction is a major driver of decibels. Should builders compensate “noise victims” for over-drilling? Or could regulation push equipment manufacturers to find new ways to dampen the sound of their kit?

Of course, none of this addresses the noise pollution we impose on ourselves. The bars and clubs we choose to visit or the music we stick in our ears. Whether pumping dance tracks in spin classes or indie rock in trendy coffee shops, people’s desire to compensate for bad noise out there by playing louder noise in here is hard to control for.

The Clean Air Act of 1956 heralded a new era of city life, one where smog and grime gave way to clear skies and clearer lungs. That fight still goes on today.

But some day, we will turn our attention to our clogged-up airwaves. The decibels will fall. #Twitter will give way to twitter. And every now and again, as we step from our homes into city life, we may just hear the sweetest sound of all. Silence.
