Footprint (ecological) (WWF)

he Ecological Footprint (EP) developed by the WWF indicates is a measure of the consumption of renewable natural resources by a human population. A population’s EF is the total area of productive land or sea required to produce all the crops, meat, seafood, wood and fibre it consumes, to sustain its energy consumption and to give space for its infrastructure. The EF can be compared with the biologically productive capacity of the land and sea available to that population. The Earth has about 11.4 billion hectares of productive land and sea space, after all unproductive areas of icecaps, desert and open ocean are discounted, or about a quarter of its surface area. Divided between the global population of six billion people, this total equates to just 1.9 hectares per person. This definition differs from Bill Rees’ who includes the area needed to assimilate human wastes
