Volcano shows we rely too much on air transport

Matthew Lynn

FOR a generation or more, no one ever gave a second thought to Iceland. Now it has shaken up the world twice in a couple of years.

First its banks collapsed in the most dramatic illustration of the fragility of our financial system. Now an Icelandic volcano is spewing ash into the sky, prompting a shutdown of European airspace. The continent is paralysed. Planes are grounded.

Travellers are stuck thousands of miles from their families and workplaces. Business is grinding to a halt.

Both happenings are strangely similar. They are, to borrow a phrase from financial theory, "black swan" events: unexpected developments, coming out of nowhere, for which no one has any kind of contingency plan. And they are a warning about the fragility of the modern economy.

The lesson, surely, is to be aware of how easily whole industries can be blown apart. And to make sure we build systems robust enough to survive the worst that can be thrown at them.

The Eyjafjallajökull volcano has caused chaos on a massive scale. Since the April 14 eruption, more than 80,000 flights have been cancelled. Its last major eruption in 1821 lasted more than a year.

It can teach us useful lessons, if we want to learn them.

First, we are dependent on air travel. Our economy is kept in motion by fleets of jetliners and a network of airports. Business revolves around meetings in hotels next to the runways. Documents are ferried around by air. But air networks are very delicate.

They are constantly at the mercy of the weather, mechanical failure, strikes and terrorist plots. Perhaps the chaos of the last few days will teach us that our economy needs to be more grounded, both metaphorically and literally.

Second, we forget that distance counts. Globalisation has made the world seem a very small place. Emails ping from continent to continent in the blink of an eye.

Social networks allow us to be friends with people thousands of miles away as easily as if they lived on the next street. Money flashes from country to country, and ideas and trends zip around the world.

And yet, when the technology breaks down, it is a long way from Helsinki to Madrid, or from New York to Berlin. Try doing that journey the old-fashioned way -- by car, by boat, or on foot -- and you suddenly realise the distance between places still counts for a lot.

Third, we need to prepare for the unexpected. A couple of years ago, it was the financial system that fell to pieces.

Right now, it is the transport system. In both cases, the cause was something we didn't expect, or make any plans for.

We thought hedge funds might blow up the banks -- instead some rather dull-looking mortgages did. We thought terrorists might spread chaos through the airline system -- it turned out that ash from an Icelandic volcano did that job.

Air travel is useful. But we shouldn't depend on it as much as we do. We shouldn't rely so completely on any single network, whether it is financial or technological.

That should be obvious to everyone.

But sometimes it takes something as powerful as a volcanic eruption to make a simple point. (Bloomberg)
