The World: humans and wilderness

filed under: @ 09:10:34 by 7colors

Analysis of the human footprint map indicates that 83% of the land's surface is influenced by one or more of the following factors: human population density greater than 1 person per square kilometer, within 15 km of a road or major river, occupied by urban or agricultural land uses, within 2 km of a settlement or a railway, and/or producing enough light to be visible regularly to a satellite at night. 98% of the areas where it is possible to grow rice, wheat or maize (according to FAO estimates) are similarly influenced.

The last of the wild represent the largest, least influenced areas (defined as above) in all the biomes of the world in all the world's regions. They represent a practical starting place for long-term conservation, places where the full range of nature may still exist with a minimum of conflict with existing human structures.
