Sustainable yield is the amount of a resource that humans can harvest without over-harvesting or damaging a potentially renewable resource. [1]In more formal terms, the sustainable yield of natural capital is the ecological yield that can be extracted without reducing the base of capital itself, i.e. the surplus required to maintain ecosystem services at the same or increasing level over time.

The concept of maximum sustainable yield is not always easy to apply in practice. Estimation problems arise due to poor assumptions in some models and lack of reliability of the data. [8] [25] Biologists, for example, do not always have enough data to make a clear determination of the population's size and growth rate. Calculating the point at ...
This common practice damages the overall credibility of corporate sustainability claims and leads to mistrust of the consumers. This general inconsistency between a company's messages and it actions could finally explain the value-action gap between consumers strongly expressed concerns about socio-ecological issues and their nevertheless ...
Ecological yield is the harvestable population growth of an ecosystem. It is most commonly measured in forestry : sustainable forestry is defined as that which does not harvest more wood in a year than has grown in that year, within a given patch of forest .
Scientists say 7,500 tons annually is the sustainable limit, yet the fishing industry continue to harvest 60,000 tons. In wild fisheries, overexploitation or overfishing occurs when a fish stock has been fished down "below the size that, on average, would support the long-term maximum sustainable yield of the fishery". [22]
In environmental science, optimum sustainable yield is the largest economical yield of a renewable resource achievable over a long time period without decreasing the ability of the population or its environment to support the continuation of this level of yield, and enables an ecosystem to have a high aesthetic value.
Overall, the influence of experts on sustainable consumer choices can be instrumental in driving positive change towards a more sustainable global marketplace and society. However, as expert knowledge tends to rely on technical, scientific data and an urban-dominant perspective, it thus issues solutions that are also technical and suited for ...
The concept of maximum sustainable yield (MSY) has been used in fisheries science and fisheries management for more than a century. Originally developed and popularized by Fedor Baranov early in the 1900s as the "theory of fishing," it is often credited with laying the foundation for the modern understanding of the population dynamics of fisheries.
