Conservation conversations often rely on technical vocabulary. Colcom Foundation‘s educational materials define several terms that help clarify how the foundation thinks about environmental protection and why it funds the projects it does. Each term connects to a different part of the foundation’s thinking.

Measuring Human Demand

The first is the ecological footprint. The Global Footprint Network offers this definition: “A measure of how much area of biologically productive land and water an individual, population or activity requires to produce all the resources it consumes and to absorb the waste it generates, using prevailing technology and resource management practices.”

When that footprint grows too large, a second concept applies. The Global Footprint Network describes biocapacity overshoot as follows: “An ecological deficit that occurs when a population’s ecological footprint exceeds the biocapacity of the area available to that population, requiring the liquidation of natural assets or the emission of carbon waste into the atmosphere.”

Put simply, overshoot means drawing down savings. The Dasgupta Review (2021) estimated that humanity uses natural capital 1.6 times faster than Earth can regenerate it.

Economics and Land Law

The Jevons paradox, also called the rebound effect, comes from economics. William Stanley Jevons first described it in 1865. The principle holds that efficiency improvements tend to increase total consumption of a resource, because they reduce its effective cost and expand demand. Colcom Foundation relies on this idea to argue that efficiency gains alone cannot reverse environmental degradation when population continues to grow.

The final term is legal. A conservation easement is a voluntary agreement between a landowner and a land trust or government agency that permanently limits specified land uses. Its purpose is to protect a property’s conservation, scenic, or agricultural values. Because the limits are permanent, the protection lasts beyond any single owner.

Easements matter to Colcom Foundation because permanent land protection is one of its core approaches. Together with reducing the overall ecological footprint, it forms the practical side of the foundation’s mission to foster a sustainable environment and ensure quality of life for all Americans.
