Blog reader Panalion sent me a photo taken in Amsterdam’s Botanical Garden. It is of a map showing coffee and tea flows from producing countries to mainly Europe and North America. Panalion writes “I thought you might like this Sankey map I found attached to a cable between two palm trees. There were chairs set up to accomodate school classes”.

This map is for didactic purposes and features no absolute figures and no year. In addition to the export flows of coffee and tea shown as arrows the map also has circles of three different sizes representing percentage of world production of coffee, tea and cocoa in the originating country.

Infographers might have better ways of showing this information. But in this case I think it is sufficient to get the message across to the target audience, the school kids.

After all these Sankey diagrams for energy flows, flows of carbon, phosphorus, and the like here is a special one for all those of you, who are coffee addicts – like me. Saman Zomorodi on his blog ‘Saman’s System, Sites and Buildings’ features a coffee flow Sankey diagram in this post.

This is an infographic for global coffee production. Producers are on the left side, coffee consumers are on the right. The dark brown flows are for developing nations, while the milk coffee color ones are for developed nations. No quantities given in the diagram, so we don’t learn the actual absolute figures.

However, “this allows the reader to actually see where coffee is being made and how far it actually travels to another world region. As evident in the diagram, almost all coffee is produced in the developing nations, while the majority of it is consumed in the developed nations. This relationship underscores the unproportional amount the developed world consumes, while the developing nations have to pay many hidden costs.”

The original image is >2MB and I had to resize it with a loss in quality. Visit Saman’s blog to download a highres version of the diagram.
