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?
