 Yield (economics) - Encyclopedia, History, Geography and Biography   (Site not responding. Last check: 2007-11-06)
The yield of a financial instrument, usually a debt or other fixed income instrument, is the amount the holder is paid each year for leaving his or her money invested in that instrument.
Unlike a corporate dividend, a yield is fairly certain, unless there is a bankruptcy.
While yields vary with inflation, they tend to fit in a fixed order: the least risky instruments, such as Treasury bonds, yield the least, then safe and "guaranteed" instruments like long-term deposits, then overnight deposits, and so on to the various municipal bond and corporate bonds.

 Yield - Simple English Wikipedia
A key issue is the contrast with ecological yield: some people advocate a monetary reform to ensure that the requirement to repay global debt does not reduce the Earth's carrying capacity or carbon sink capacity.
If the payments of economic yield to holders of global debt exceed that which can be borne by the natural renewal of the Earth, (for instance, its current solar income) that is an energy subsidy.
In practice, this is an issue with money supply and monetary policy and does not affect each individual holder of a bond or other debt, except insofar as it may lead from time to time to odious debt writeoffs or a major credit crisis.

Some consider it is a basic unit in ecology, only a structured functional unit in equilibrium, caracterized by energy and matter flows between the different elements that compose it.
The abstract notion of ecological health, and the more specific biodiversity metric, attempts to measure the robustness and capacity for recovery of a natural ecosystem.
Ecosystem valuation (of which the most extreme is the attempt to assign the value of Earth) and environmental health measures are usually thought to be part of economics rather than being within the science of ecology.

Yield Potential The gap between average yields presently achieved by farmers and yield potential is determined by the yielding ability of available crop varieties or hybrids and the degree to which crop and soil management practices allow expression of this genetic potential.
Evans (11) defines crop yield potential as the yield of a cultivar when grown in environments to which it is adapted, with nutrients and water nonlimiting and with pests, diseases, weeds, lodging, and other stresses effectively controlled.
Precision Agriculture The gap between average farm yields and the yield potential ceiling must shrink during the next 30 years because the yield potential of tropical rice and maize appears to be stagnant and wheat yield potential is increasing more slowly than the expected increase in demand (Tables 1 and 2~.

 Eco-capitalist - Wikipedia, the free encyclopedia
Its central idea is that capital exists in nature as "natural capital" (self-renewing productive ecosystems that have a measurable ecological yield or tangible benefit to humans) on which all wealth depends.
Other forms of capital that are created by humans (like infrastructural capital and financial capital) simply extend and optimize this natural capital with creativity, training and trust.
The Kyoto Protocol, for instance, assigns a de facto value to human life in developing nations of about 1/15 the value of a life in developed nations, based on the ability of the latter to pay to prevent deaths due to climate change.

Because ecological effects vary with the environmental manipulation or insult, the location, the biological com- munities present, the scale, and other factors, a major question concerning the usefulness of generic (and analog) studies is the extent to which their results can be applied to a particular site and problem.
The most useful generic studies identify, characterize, and explain the major ecological effects of a particular environmental insult or manipulation and provide a framework for understanding the effects of variations in location and other factors.

Ecological uncertainty is incorporated into a dynamic source-sink model of a marine reserve and a fishery to solve for the economically optimal reserve size.
The model shows that reserves create a resilience effect that generates a positive payoff to fishers, whether or not the fishery is initially overexploited, and even if harvesting is optimal and the population is persistent.
