Groundwater supply sustainable yield is herein defined as how much water can be withdrawn from an aquifer system, where and for how long, with acceptable physical, economical, environmental, social, cultural, institutional, and legal consequences.
What is meant by 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 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 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 the difference between yield and sustainable yield?
Safe yield has functional relation with water withdrawal and its temporal pattern while the sustainable yield caters long term availability of water resource through replenishment in dry season and withdraw in wet season. Sustainability is a very complex concept.
What are differences between sustainable yield and safe yield of ground water?
Hello, To me the “sustainable yield” of an aquifer refers to its recharge whereas the “safe yield” refers to a lower value than recharge and the is determined on parameters (economical and ecological) that define what would be a “healthy aquifer”.
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 are sustainably managed fisheries?
Managing fisheries sustainably is an adaptive process that relies on sound science, innovative management approaches, effective enforcement, meaningful partnerships, and robust public participation. Effective fishery management starts with accurate scientific information about fish and fisheries.
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 is specific yield in groundwater?
Specific yield is part of the total porosity of a porous rock or sediment. Specific yield is the amount of water that is actually available for groundwater pumping, when sediments or rocks are drained due to lowering of the water table. Specific yield depends on the distribution of pores, their shape, and grain size.
What is yield in water supply?
Yield is used to characterize the capacity of a water resource to serve as a long-term water supply. Safe yield or firm yield in the context of water reservoirs is defined as the maximum quantity of water which can be guaranteed during a critical dry period (Linsley and Franzini, 1979).
What is sustainable yield ESS?
STUDY. Only $47.88/year. What is sustainable yield? SY is calculated as the rate of increase in natural capital that can be exploited without depleting the original stock or its potential for replenishment.
What is sustainable groundwater yield?
A sustainable groundwater yield for an aquifer is considered here to fall within the range of natural groundwater discharge during the baseflow season and the higher discharge that occurs during the spring freshet and later season precipitation events. How is it applied?
What is “sustainable groundwater management?
SGMA defines “sustainable groundwater management” as the “management and use of groundwater in a manner that can be maintained during the planning and implementation horizon without causing undesirable results.”
Is there a safe yield for groundwater pumping?
Attempts to limit groundwater pumping have been commonly based on the concept of safe yield, defined as the attainment and maintenance of a long term balance between the annual amount of ground water withdrawn by pumping and the annual amount of recharge.
What is “safe yield”?
A considerable amount of groundwater resides beneath the province, and a significant amount of water recharges the system annually. However, in keeping with the concept of “safe yield”, only a fraction of that water can be safely used in support of human activities, while maintaining ecological and environmental integrity of our basins.
