Everything about Ecological Yield totally explained
Ecological yield is the harvestable
population growth of an
ecosystem. It is most commonly measured in
forestry - in fact
sustainable forestry is defined as that which doesn't harvest more wood in a year than has grown in that year, within a given patch of forest.
However, the concept is also applicable to
water, and
soil, and any other aspect of an ecosystem which can be both harvested and renewed - the so-called
renewable resources. The
carrying capacity of an ecosystem is reduced over time if more than the amount which is "renewed" (refreshed or regrown or rebuilt) is consummed.
Nature's services analysis calculates the global
yield of the
Earth's
biosphere to humans as a whole. This is said to be greater in size than the entire human economy. However, it's more than just yield, but also the natural processes that increase biodiversity and
conserve habitat which result in the total value of these services. "Yield" of
ecological commodities like wood or water, useful to humans, is only a part of it.
Very often an ecological yield in one place offsets an
ecological load in another.
Greenhouse gas released in one place, for instance, is fairly evenly distributed in the
atmosphere, and so
greenhouse gas control can be achieved by creating a
carbon sink literally anywhere else.
Ecocide is thought by some
green economists to be accelerated by
debt instruments which demand a
yield (economics) greater than the ecological capacity to renew. This is a major question in
monetary reform.
