What is an ecological footprint?

The ecological footprint measures how much land and water a population would need to supply its resources and absorb its wastes. It converts everything a society uses—energy, food, housing, transportation, goods, and waste management—into an equivalent amount of productive land and sea, usually shown in global hectares. This lets us compare how demanding different lifestyles are on Earth’s ecosystems and see if a population is living within the planet’s means or exceeding them (overshoot). It’s not about population growth rate, GDP adjusted for environmental costs, or a map of protected areas; those other ideas describe different concepts altogether.
