Presentation transcript:

Ecological Footprints

Measures human demand on nature Tracks demand through an ecological accounting system contrasts the biologically productive area that people use for their consumption to the biologically productive area available within a region or the world (biocapacity) it is a measure of human impact on Earth's ecosystem reveals the dependence of the human economy on natural capital

The ecological footprint = the biologically productive area needed to provide for everything people use: fruits and vegetables, fish, wood, fibers, absorption of carbon dioxide from fossil fuel use, and space for buildings and roads. Biocapacity = the productive area that can regenerate what people demand from nature. Measured in Hectares or Acres 2.47 Acres per Hectare

Ecological footprints are used in sustainability assessment studies footprint assessments show how big humanity's demand is compared to what planet Earth can renew Global Footprint Network calculates the ecological footprint from UN and other data for the world as a whole and for over 200 nations. As of 2013, humanity has been using natural capital 1.6 times as fast as nature can renew it Ecological footprints are used in sustainability assessment studies
