Global hectare is a unit of measurement used to calculate the ecological footprint, which represents the amount of natural resources a person consumes based on their lifestyle. The global hectare measures the average productivity of all Earth's natural surfaces in one year, expressed in hectares.
This unit is used to calculate the ecological footprint, i.e., how many hectares of land and water a person uses to produce food, clothing, energy, and other necessities. The concept of ecological footprint and the global hectare was developed to better understand how humans utilize natural resources and how this impacts the environment.
The global hectare can be used to assess the ecological footprint of an individual, community, region, or even an entire country. It serves as a tool for managing natural resources and promoting sustainable environmental management, as well as for comparing the ecological footprints of different countries or regions.
