The Ecological Footprint Network has some interesting maps and animations of “Footprint Intensity” between 1961 and 2001. The maps also show how the human Footprint has increased 2.5 X between 1961-2001.
Ecological footprint intensity is the footprint per 1/2 degree grid cell. These maps are made by combining population distribution maps and national level ecological footprint data.
The maps were created by Chad Monfreda at SAGE University of Wisconsin – Madison.
I previously posted on SAGE maps of disease burden and mapping humanity’s footprint.
Also, Marc Imoff et al (Nature 2004) have another map of human ecological appropriation.
