Ecological Deficit/Reserve
The difference between the biocapacity and ecological footprint of a region or country. An ecological deficit occurs when the footprint of a population exceeds the biocapacity of the area available to that population.


footprint: The footprint is a measure of human demand on the Earth'secosystems. It is a standardized measure of demand fornatural capital that may be contrasted with the planet'secological capacity to regenerate.

Indicator: A characteristic of the environment that, when measured, quantifies magnitude of stress, habitat characteristics, degree of exposure to a stressor, or response to exposure.

Ecological Efficiency: the percentage (usually around 10%) of useful energy that passes from one trophic level in a food chain to another. Shorter food chains tend to lose less energy.

stress: See stressors.

Ecological rucksack is the total weight of material flow 'carried by' an item of consumption in the course of its life cycle.

Indicator: A characteristic of an ecosystem that is related to, or derived from, a measure of biotic or abiotic variable, that can provide quantitative information on structure and function.
