Globally, the available ecologically productive land area included in the Ecological. footprint analysis is 1.89 hectares for each person. The footprint takes into account fossil. fuel use, cropland, forests, nuclear and hydroelectric power, fisheries and buildings.
From 1961 to 2008, the Mediterraneanâs per capita Ecological Footprint increased by 52 percent, while per capita biocapacity in the region decreased 16 percent. The average Mediterranean resident now has an Ecological Footprint of 3.1 global hectares (gha), but only 1.3 gha per person are available in the region.rom 1961 to 2008, the Mediterraneanâs per capita Ecological Footprint increased by 52 percent, while per capita biocapacity in the region decreased 16 percent.
