What is sustainable yield?

What is sustainable yield?

The sustainable yield of renewable natural resources is traditionally defined as the extraction level of the resource which does not exceed the growth. Context: The sustainable yield refers to total fellings and not only to timber removed for own consumption and use. …

What is an example of sustainable yield?

The term sustainable yield refers to the harvest of a specific (self-renewing) natural resource—for example, timber or fish. Such a yield is one that can in principle be maintained indefinitely because it can be supported by the regenerative capacities of the underlying natural system.

What is sustainable yield and why is it important?

The term sustainable yield is most commonly used in forestry, fisheries, and groundwater applications. Sustainable yield is an important component of sustainable forest management. In the forestry context it is the largest amount of harvest activity that can occur without degrading the productivity of the stock.

What is sustainable yield forestry?

Sustained yield ensures the feasibility of continuous, long-term exploitation of available resources to obtain regular harvests. Sustained yield use is most commonly actively applied in forestry.

What is sustainable yield quizlet?

Sustainable yield is the highest rate at which we can use a renewable resource indefinitely without reducing its available supply. Humans are using resources at an unsustainable rate.

What is sustainability and the maximum sustainable yield?

The maximum sustainable yield (MSY) for a given fish stock means the highest possible annual catch that can be sustained over time, by keeping the stock at the level producing maximum growth. The MSY refers to a hypothetical equilibrium state between the exploited population and the fishing activity.

What happens if a fishery is overexploited?

It can change the size of fish remaining, as well as how they reproduce and the speed at which they mature. When too many fish are taken out of the ocean it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals.

What does yield mean in terms of stocks?

Yield is the income returned on an investment, such as the interest received from holding a security. The yield is usually expressed as an annual percentage rate based on the investment’s cost, current market value, or face value.

What is overfishing and sustainable yield?

The European Commission considers a fish stock to be overfished when its biomass is below BMSY. In that situation, it is unable to produce the maximum sustainable yield. Overfishing occurs when more than the sustainable share is taken out of a given fish stock, i.e. when the fishing rate is above FMSY.

Can sustainable yield apply to fossil fuels?

The maximum rate it which people can use a renewable resource without reducing the ability of the resource to renew itself is called a sustainable yield. All fossil fuels such as oil, coal, natural gas and minerals and metals are nonrenewable resources.

What does sustainable yield refer to?

In sustainability: Forms of sustainability The term sustainable yield refers to the harvest of a specific (self-renewing) natural resource—for example, timber or fish.

What does sustained yield mean?

Definition of sustained yield. : production of a biological resource (such as timber or fish) under management procedures which ensure replacement of the part harvested by regrowth or reproduction before another harvest occurs.

What is optimum sustainable yield?

In population ecology and economics, optimum sustainable yield is the level of effort (LOE) that maximizes the difference between total revenue and total cost. Or, where marginal revenue equals marginal cost.

What is initial yield?

initial yield. noun. the estimated yield of an investment fund at the time when it is launched.
