The systematic allocation of the cost of a natural resource from the balance sheet to the income statement.

One of the primary constraints of the environment on sociocultural systems.  Refers to the limited supplies of natural resources (although the limits are unknowable, that there are limits can be inferred). These limits can often be stretched through the use of technology (see also Pollution, and Intensification).

An accounting device, used primarily in tax computations. It recognizes the consumption of an ore deposit, a mine's principal asset. Depreciation

The concept of depletion is that counterpart of depreciation which is normally applied in extractive industries. The need for a different concept may ...

Method of computing a deduction to account for a reduction in value of extractable natural resources.

The loss of water from surface water reservoirs or ground water aquifers at a rate greater than that of recharge.

The value of a naturally occurring mineral deposit is a function of (1) the market value of the mineral, and (2) the concentration of the mineral in the mineral deposit.

The reduction in value of mineral deposits as it is produced.

A decline in reservoir pressure that can be detected during a formation test or as a result of the production of oil and/or gas of the reservoir of an oil field.
