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. [2]
The maximum sustainable yield is the largest yield that can be taken from a population at equilibrium. In figure 3, if H {\displaystyle H} is higher than H 2 {\displaystyle H_{2}} , the harvesting would exceed the population's capacity to replace itself at any population size ( H 3 {\displaystyle H_{3}} in figure 3).
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. [1]
Three ways of defining a sustainable fishery exist: Long term constant yield is the idea that undisturbed nature establishes a steady state that changes little over time. Properly done, fishing at up to maximum sustainable yield allows nature to adjust to a new steady state, without compromising future harvests. However, this view is naive ...
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 .
The suit accuses the lender of violating its own mission of promoting sustainable development while doing no harm. The IFC failed “to prevent and mitigate harms to the property, health, livelihoods, and way of life of many of the people who live near the Tata Mundra Plant,” says the complaint.
Consistent and sizable dividend raises paired with a languishing stock price have boosted Starbucks' yield to 2.7% -- which is considerably higher than the S&P 500's dividend yield of 1.2%.
For example, if Apple pays $0.63 per share in dividends every quarter, its annual dividend rate is $2.52, or four times $0.63. But when it comes to dividend yield, the dividend rate is only half ...
