Biocapacity Deficits and Reserves
Biological capacity, or biocapacity, is a way to measure an area’s ability to produce biological materials necessary for life, such as food, and to absorb its carbon dioxide emissions. Deficits and reserves are determined by measuring an area’s capacity against its ecological footprint—the area required to support an ecosystem’s population.
