Background
Sustained yield is a concept in resource management and economics that balances the use of a natural resource with its ability to regenerate and maintain its productivity indefinitely. The goal is to ensure long-term sustainability without damaging the resource’s future productivity.
Historical Context
The concept of sustained yield arose in the early 20th century within the realm of forestry. It has since expanded to encompass various fields including agriculture and fisheries, as awareness of environmental impacts and sustainability has grown.
Definitions and Concepts
Sustained Yield: A level of output that can be continued indefinitely without impairing the future productivity of the natural resources used.
This involves practices that do not deplete the resource permanently but allow for regeneration and long-term viability.
Major Analytical Frameworks
Classical Economics
Classical economics often focused more on the immediate productivity and less on sustainability. However, some classical economists did recognize limits to resource extraction.
Neoclassical Economics
Neoclassical economics includes considerations of resource depletion and incorporates the concept of sustainable management within the broader scope of efficient resource allocation.
Keynesian Economics
Keynesian economics concentrates more on aggregate demand and economic cycles but can incorporate sustained yield principles into broader economic policies focusing on long-term economic sustainability.
Marxian Economics
Marxian economics addresses the exploitation of labor and resources, advocating for sustainable use of resources as a resistance against capitalist nature of overexploitation for profit.
Institutional Economics
Institutional economics examines the role of policies, regulations, and organizations in promoting sustained yield and managing common resources.
Behavioral Economics
Behavioral economics may investigate how human psychology impacts resource usage and how promotion of sustained yield practices can be framed to influence sustainable behaviors.
Post-Keynesian Economics
Post-Keynesian economics emphasizes market imperfections and therefore could strongly support regulatory policies aimed at sustained yield to correct potential market failures in resource management.
Austrian Economics
Austrian economists might argue for private property solutions and market mechanisms as a means to achieve sustained yield through individual responsibility and long-term planning incentstd by ownership.
Development Economics
Development economics examines sustained yield from the perspective of marginalized and developing communities, ensuring that development efforts do not deplete their resource base.
Monetarism
Monetarists may indirectly support sustained yield through policies that stabilize long-term economic conditions, which can foster an environment conducive to sustainable practices.
Comparative Analysis
Different economic schools of thought place varying degrees of emphasis on sustained yield, implementing diverse methods for incorporating sustainability into economic activities.
Case Studies
- Forestry: Successful cases where a regular cycle of felling and replanting has maintained forest productivity.
- Agriculture: Practices like crop rotation and organic farming that keep the soil fertile without overexploitation.
- Fisheries: Example of regulated fisheries where limited harvesting prevents the collapse of fish stocks.

Related Terms with Definitions
- Depletable Resources: Natural resources that can be completely used up or made unusable over time.
- Renewable Resources: Resources that can be replenished naturally over time, given proper management practices.
By understanding and implementing sustained yield practices, we can ensure that natural resource use does not compromise future productivity and long-term environmental health.
