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.

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.
