URBAN EARTH

URBAN ADVENTURE

SALISBURY

For the past six years I have been fascinated by the idea of ecological footprints. So, in advance of the three URBAN EARTH walks this summer I decided to walk the radius of one city’s ecofootprint.

Why you might ask? The sphere of influence of any settlement goes beyond the sign the sign that welcomes you to it. When experiencing any place the temptation is to think that its boundaries are fixed, but they are not. The flows of ideas, goods, resources, passions, people, memories, capital, fact and fiction mean that places spread and pulse across through space with optical, tarmac and copper tentacles reaching out in networks across the land. Like satellites first observing the calderas of super-volcanoes which were too big to be seen from the ground, ecological footprinting provides a vision of our impact on the Earth

Salisbury is a relatively small imprint on the English landscape wedged between mixed farmlands the military firing ranges. Covering around 11sqkm and with a population of around 44,000 people this city, like all other cities, has a hidden geography. The area of land and water needed to sustain the lifestyles of its people (its ecological footprint) is 2,186sqkm, 600sqkm larger than London’s urban footprint.

Last weekend I photographed a walk to the centre of Salisbury from the conceptual boundary of this ecological footprint. With the help of the WWF One Planet campaign we worked out that I would need to travel 26km from the city centre, of which only 2km would be made up of the city’s urban footprint. Out of all cities in England, Salisbury has the third best, yet if everyone in the world shared the lifestyle of people in Salisbury we would need nearly two additional planets.

Over the course of a day I took nearly 5,000 photographs, one for every eight paces I walked. By animating the images at 24 frames per second URBAN EARTH: SALISBURY (re)presents the city, not by the physical geography that is experienced by its people and visitors, but by our ability to imagine and understand the relationship this city has on the rest of the planet. This walk is not a real walk through a real footprint. In reality Salisbury is dependent on not just its rural surroundings but the rest of the world. For this film to be a true representation it would be necessary to walk through fields of cocoa, bananas, iron and the other resources that the city imports.

In a world which is continually distorted by our means of travel, channels of media and lack of understanding walking to the limits of the city’s footprint puts the impacts of humanity into perspective. By intentionally bending and representing space our minds can better make sense of the true size of cities and the issues that they present us with and that is exactly what I am doing with URBAN EARTH

Nice work! This has not only made me think about the impact of cities in a different way but I can see applications in the classroom. I wonder how far I would have to walk from Portsmouth? Well worth looking into I think….

Were the shots taken looking at Salisbury or away?

I started the walk just east of Winchester (which has the worst footprint for a city in England) and walked into the centre of Salisbury from there. This film is actually a reversed version of the walk. I think it is good to see the start of the urban area first, but I’ll be uploading the forward version later too.

According to a recent WWF report Portsmouth has the 10th largest ecological footprint compared to the number of people who live in it. The average person has a footprint of 5.79 global hectares (3.21 planets would be needed if everyone in the world lived like that).. It would be a big walk, let me know if you plan to do it.

You can see the WWF report here:

Here are some stats on Portsmouth from the last census:
http://www.statistics.gov.uk/census2001/portsmouth_urban_area.asp

Based on some quick calculations I think (need to double check) you would have to walk 56km to get from the centre of Portsmouth to the edge of its ecological footprint.. but this is only based on its population at the last census and only the people who live there and not all the business and government activities.

56km! I’ve done that in a day before but didn’t feel so good! Thanks for the stats and the links though I’ll look into this as I usually do my walking in rural locations so it would a be an intersting contrast.

I like moving towards the city as it also gives an aiming point!

Will do some thinking!

I was lucky enough to see your presentation at Interesting2008; and I happen to live in the city with the largest ecological footprint in the UK. I also recognise exactly the spot where you started this walk, and this is a route that I’ve walked and cycled many times. The fact that this marks the boundary of Salisbury’s ecological footprint is a real eye opener to me; and it raise in my mind exactly where I’d have to walk to in order to reach the boundary of my own city’s resource consumption.

Great stuff!

Sorry – should be ‘raises in my mind…’.

Dear Daniel,
Good one. Easy for common people to to know their surrounding and the rural urban fringe of a city. But I have my doubt whether It will be possible for Mumbai. India. Will have to give a thought.
