What happens if you lock two creative people and three geographers in a pub, pour some statistics about their city over them and let their mind work out the rest? You could find out the result at this year’s Festival of the Mind of the University of Sheffield that went on for 10 days throughout Sheffield. Nick Bax and Daniel Fleetwood of Humanstudio were the two creative minds that teamed up with Carl Lee of Sheffield College and Danny Dorling & myself from the University of Sheffield to take a look at the impact of higher education on the city in a slightly unusual way. The result of this collaboration is the short film ‘A City in Context‘ viewed during the festival and now available online. Continue reading
People are dying all the time. Wars are just one of the many causes of death, but certainly one of the more avoidable ones. WHO’s Global Burden of Disease (GBD) study is the key publication containing global health statistics which can help to understand the relevance of geography in relation to the mortality patterns and the prevalence of certain diseases.

499 years after Mercator’s birth we may feel that the age of discovery is long gone. We seem to have explored almost every patch of our planet, considerably supported by Mercator’s famous world map that allowed sailors for the first time to reliably navigate across the world’s oceans. His innovation was a significant contribution to the early days of globalisation. Globalisation has turned our planet into a human planet, where people have become a substantial component of the processes that influence our livelihoods – some go as far as calling this a new geological era, the anthropocene. But while we have maps and images of every spot of the earth, we do not fully understand the human environments and interrelations to the natural environment. Normal maps show where sheep and other lovely creatures of nature live but hide much of the so important populous spaces of humanity.
The maps that I created as part of my PhD research are based on a novel cartogram mapping technique, deploying Gastner/Newman’s diffusion-based cartogram algorithm in a new way. The maps give every person living on this planet the same amount of space, while reducing the least populated places to a minimum. The map projection is calculated from an equally distributed population grid so that, unlike in other cartograms, the transformed grid cells preserve an accurate geographical reference. This allows us to map a diverse range of geographical layers on top of the population projection. The new maps show the social and physical environment in relation to population and provide a fresh perspective on the complex geography of the 21st century world. The following animation shows a series of maps that demonstrate the visual capabilities of the technique (the video can be switched to HD resolution by clicking the 360p note in the bottom panel):
