Is aerotropolis Songdo really the city of the future?

The ‘aerotropolis’ has been described by U.S. business consultant John Kasarda, the pioneer of the concept, as the “city of the future”. The notion of building a city around an airport, not the other way round, has been deemed to be crucial for economic development. Just as urban areas sprawled around railroads in the 1800s, and highways in the 1900s, the thinking is that business and commerce will jump at the opportunity to be based near a world-class, international hub.

Amsterdam Schiphol and Seoul Incheon have been widely seen as the two poster children for the concept of the aerotropolis. But are airport cities really that glamorous in reality?

Fast forward eleven hours from Heathrow, and one lands in the stylish Terminal 1 of Seoul Incheon (IATA code: ICN), a routine prize-winner in the "World’s Best Airport’ awards. Every time I have landed there, there is some new addition to the hi-tech gizmos on show in the arrivals lounge, whether high-tech sanitation in the restrooms, a high-speed railway linking Incheon with the rest of Seoul, or, on my recent arrival, automated robots making sure the floors of Arrivals were polished to perfection.

Yet much of the attention has focused not on ICN, but its aerotropolis of Songdo, officially the Songdo International Business District. A ‘smart city’ built from scratch on reclaimed land, Songdo was destined to be the prototype cosmopolitan aerotropolis, the city of the future: home to international university campuses, globe-trotting businessmen, multinational financial firms, as well as a place for high-end tourism. The 2012 Presidents Cup golf tournament was played at the Jack Nicklaus-designed golf course in Songdo. What better way to attract an international clientele?

Yet have a look around Songdo, and it feels like a ghost town. The students are there, businessmen come and go, restaurants and department stores open their doors, yet something is missing.

The lack of footfall and sporadic numbers of ‘cosmopolitan clientele’ were crystal clear as I walked down the deserted streets. Songdo is no exception to South Korea’s obsession with high-rise life, but more apartments are being built than tenants moving in. In what looks like a half-hearted attempt to emulate the epitome of global urban cosmopolitanism, New York, the high-rise apartments encircle a designated park named Central Park.

Songdo also promised environmental and technological progress. Amongst the city’s many accolades, it has claimed the title of the world’s first ‘smart’ city: sensors have been placed throughout the area to gather information on traffic flows, and apartments are fitted with the latest technological accouterments. The frequent-flying businessman can make video calls from the televisions in the apartments, and the global student can attend university classes remotely. Trash is collected and separated automatically, sucked out of apartments by a vacuum chute, and, within the blink of an eye, arrives at the sorting facility.

These are hallmarks of an efficient city – but only if there are car users for whom tracking pollution levels and traffic flows may be useful, if there are businessmen who actually make use of the LED television screens to conference call, and if there is enough trash to be recycled and sorted, come to that.


Speaking to those who live in Songdo and its vicinity, the hype all seems a bit much. With South Korea increasing in its technological innovation day-by-day, the ability to host a conference call from one’s LED television screen is no big deal. Similar waste collection has been tried tested in Singapore, amongst other cities: again, nothing to get excited about.

And most of all, when I asked where the cosmopolitan citizens are, the reply was simple: “They are all in Seoul, and will stay in Seoul.” Something has clearly gone wrong for Songdo, not least the fact that the city’s construction on reclaimed land has attracted its fair share of criticism from environmental groups – but a big problem is that it has failed to attract the globetrotting, frequent-flying, citizen-of-the-world.

There are plenty of airports around which commerce, retail, and residence are becoming ever more numerous, which raises the question of whether the aerotropolis is actually something new. Just as it is nothing out of the ordinary that businesses sprawled along the railroads in the 19th century, maybe the airport is just the railroad of today: it is only natural for urban life to blossom around it.

Maybe we should pay less attention to the new ‘cities’ springing up around airports, and more on the airports themselves. They may seem like mere waiting rooms to some – but they can be rich sources of architecture, technology, big data, and fascinating places in their own right. Incheon’s Terminal 2 opened in January of this year. It promises to be just as glamorous, efficient, and technologically-embedded, if not more, than Terminal 1.

So next time you see someone checking-in to a flight with an ‘ICN’ tag on their luggage, you may know one thing. They may be flying to Incheon, but chances are they will not set foot in Songdo.

 
 
 
 

Here are three ways your smartphone is screwing up the planet

Nearly five billion people worldwide will use a smartphone by 2020. Each device is made up of numerous precious metals and many of the key technological features wouldn’t be possible without them. Some, like gold, will be familiar. Others, such as terbium, are less well-known.

Mining these metals is a vital activity that underpins the modern global economy. But the environmental cost can be enormous and is probably far greater than you realise. Let’s walk through some of the key metals in smartphones, what they do, and the environmental cost of getting them out of the ground.

Catastrophic mine waste spills

Iron (20 per cent), aluminium (14 per cent) and copper (7 per cent) are the three most common metals by weight in your average smartphone. Iron is used in speakers and microphones and in stainless steel frames. Aluminium is used as a lightweight alternative to stainless steel and also in the manufacture of the strong glass used in smartphone screens. Copper is used in electric wiring.

However, enormous volumes of solid and liquid waste (termed mine “tailings”) are produced when extracting these metals from the earth. Typically, mine tailings are stored in vast impoundment structures that can be several square kilometres in area. Recent catastrophic mine tailings spills highlight the danger of improper construction methods and lax safety monitoring.

The largest spill on record occurred in November 2015 when a dam collapsed at an iron ore mine in Minas Gerais, Brazil, releasing approximately 33m cubic metres (enough to fill 23,000 Olympic swimming pools) of iron-rich waste into the River Doce. The waste inundated local villages killing 19 people and travelled 650km until it reached the Atlantic Ocean 17 days later.

This was just one of 40 mine tailings spills that have occurred in the past decade and the long-term ecological and human health impacts remain largely unknown. One thing is clear though – as our thirst for technology increases, mine tailings dams are increasing in number and size, and so is their risk of failure.

Ecosystem destruction

Gold and tin are common in smartphones. But mining of these metals is responsible for ecological devastation from the Peruvian Amazon to the tropical islands of Indonesia.

Gold in smartphones is used primarily to make connectors and wires but gold mining is a major cause of deforestation in the Amazon. Furthermore, extraction of gold from the earth generates waste rich in cyanide and mercury – two highly toxic substances that can contaminate drinking water and fish, with serious implications for human health.

Tin is used for soldering in electronics. Indium-tin oxide is applied to smartphone screens as a thin, transparent and conductive coating that gives touchscreen functionality. The seas surrounding Indonesia’s Bangka and Belitung Islands supplies about a third of the world’s supply. However, large-scale dredging of the seabed for the tin-rich sand has destroyed the precious coral ecosystem while the decline of the fishing industry has led to economic and social problems.


The most polluted place on the planet?

What makes your smartphone smart? That’ll be the rare earth elements – a group of 17 metals with weird names like praseodymium that are mined mostly in China, Russia and Australia.

Often dubbed “technology metals”, rare earths are fundamental to smartphone design and function. Crystal clear smartphone speakers, microphones and phone vibration are possible due to small yet powerful motors and magnets manufactured using neodymium, dysprosium and praseodymium. Terbium and dysprosium are also used to produce the vibrant colours of a smartphone screen.

Extracting rare earths is a difficult and dirty business, typically involving the use of sulphuric and hydrofluoric acids and the production of vast amounts of highly toxic waste. Perhaps the most disturbing and thought provoking example of the environmental cost of our smartphone thirst is the “world’s tech waste lake” in Baotou, China. Created in 1958, this artificial lake collects the toxic sludge from rare earth processing operations.

The valuable metals used to manufacture smartphones are a finite resource. Recent estimates indicate we will run out of some rare earths in the next 20 to 50 years, which makes you wonder if smartphones will still be around then. Reducing the environmental impact of smartphone use requires manufacturers to increase product lifetimes, make recycling more straightforward and be open about where they source their metals and the environmental impact. Around the world mining companies have made huge strides in practising more sustainable mining. But we as consumers also need to consider smartphones as less of a throwaway item and more of a precious resource that carries an enormous environmental burden.
