Sustainable yield

The definition of sustainable yield has changed throughout history and the term itself has been described as anthropocentric due to limitations in applying ecological complexity.

In the forestry context it is the largest amount of harvest activity that can occur without degrading the productivity of the stock.

The Act helped maintain a viable, sustainable yield, by ensuring land management, reforestation, watershed protection, a permanent timber source, and revenue distributed to local counties.

Sweden's market economy strives for maximum yield forestry which is obtained through intense forest management.

This results in a changed natural landscape with a loss in biodiversity of that ecosystem as well as key ecological processes.

[15] It may be very difficult to quantify sustainable yield, because every dynamic ecological conditions and other factors not related to harvesting induce changes and fluctuations in both, the natural capital and its productivity.

[16] Groundwater is essential for ecosystems and humans to sustain themselves as it is the largest store of distributed fresh water.

[17] In the case of groundwater there is a safe yield of water extraction per unit time, beyond which the aquifer risks the state of over drafting or even depletion.
