In the year 2000 there were approximately 15 million square km of cropland and 28 million square km of pasture which are represented in the two main maps. These are equal to 12% respectively 22% of the ice-free land surface. This is according to estimates of a study on the geographic distribution of global agricultural lands by Ramankutty et al (published in Global Biogeochemical Cycles, 2008) who used a methodology of combining agricultural inventory data and satellite-derived land cover data to come to these figures (data can be accessed via Columbia University’s SEDAC).

This April has been the wettest April on record in the UK, while parts of the country are also in official drought – leading to headlines of the wettest drought on record.
The miserable weather was (is) a good opportunity to finally produce a high-resolution version of the map series that I created during my PhD research and which I presented at last year’s conference of the Society of Cartographers in Plymouth. Continue reading
The 5th of March 2012 marks the 500th birthday of Gerardus Mercator, the creator of the world map that profoundly changed our views of the world. He was not the only one who worked on a conformal map projection in the 16th century, which was still an age of exploration and discovery. But he was the first to do the maths right and complete a world map that allowed ships to navigate around the planet by its ability to represent lines of constant course. That makes the Mercator projection a milestone in the history of cartography and remains one of the central map projections up to the present day. Continue reading
‘How to Land a Jumbo Jet’ is the catchy title of a little book published by Lonely Planet a couple of month ago. The book is a “visual exploration of travel facts, figures and ephemera” and a “visual guide to the way we live, travel and inhabit the globe”. Edited by the British graphic designer Nigel Holmes, the book follows the increased interest in information graphics that started to flourish yet again with the increasing availability of ever growing amounts of data.

Starting today the world gathers in Durban for the COP17 climate change summit. In times where economic growth is more anticipated than a decline in carbon emissions, the prospects for a successful successor to the Kyoto protocol (coming to an end in 2012) is quite unlikely, and it will be interesting to see, what ‘success’ the delegates have to announce for saving the world from mad and often also tragic consequences of changing climate patterns.
