Sustainable Yield

Definition

Sustainable yield refers to the maximum amount of natural resources that can be harvested or used without depleting or damaging the resource base over the long term.

Analogy

Imagine sustainable yield as fishing in a lake. If you catch fish at a rate that allows them enough time to reproduce and grow, you'll have a steady supply of fish for years to come. But if you overfish and take more than what can be naturally replenished, eventually there won't be enough fish left in the lake.

Related terms

Carrying Capacity: Carrying capacity is the maximum number of individuals an environment can sustainably support without causing long-term damage or depletion of resources. It is related to sustainable yield because both concepts involve determining limits for resource use.

Overexploitation: Overexploitation occurs when a resource is harvested or used at an unsustainable rate, leading to depletion or irreversible damage. It is the opposite of sustainable yield and highlights the importance of managing resources responsibly.

Ecosystem Services: Ecosystem services are the benefits that humans receive from ecosystems, such as clean water, air purification, and pollination. Sustainable yield ensures that these services can be maintained for future generations by avoiding excessive resource extraction.
