If a population’s Ecological Footprint © exceeds the region’s biocapacity, that region runs a biocapacity deficit. These areas, especially if left unharvested, can also serve to absorb the waste we generate, especially our carbon emissions from burning fossil fuel.īoth the Ecological Footprint and biocapacity are expressed in global hectares-globally comparable hectares with world average productivity.Įach city, state or nation’s Ecological Footprint © can be compared to its biocapacity, or that of the world. On the supply side, a city, state or nation’s biocapacity represents the productivity of its ecological assets (including cropland, grazing land, forest land, fishing grounds, and built-up land). Typically these areas are: cropland, grazing land, fishing grounds, built-up land, forest area, and carbon demand on land. The Ecological Footprint © tracks the use of productive surface areas. It measures the ecological assets that a given population or product requires to produce the natural resources it consumes (including plant-based food and fiber products, livestock and fish products, timber and other forest products, space for urban infrastructure) and to absorb its waste, especially carbon emissions. On the demand side, the Ecological Footprint © adds up all the biologically productive areas for which a population, a person or a product competes. Ecological Footprint © accounting measures the demand on and supply of nature.
