Posted: Sun Jul 16, 2006 10:07 pm    Post subject: single math formual to describe the condition of the environment?

In economics there is a simple math formual to measure the condition of
an economy (GDP)

Just wondering if anyone has thought about a formula to describe the
condition of the environment?

It's not a trivial task, since condition of the environment depends
upon so many terms, to give ya an idea of some of the variables I've
been looking at:

http://www.maweb.org//en/products.global.condition.aspx

I was thinking of some kind of weighted averages, but since I'm not a
biologist didn't know what scaler multiples to use...

anyone have a suggest or kind of a paper they could direct me to?

the reason I ask was because I'm kind of curious to plot GDP vs
(condition of the environment), I've been pondering this idea off and
on for awhile and sort of blogged the reasons why on my site...

That is incorrect; there are many metrics in economics.

Probably; if so, it would be just as simplistic as relying on the GDP
as the sole metric of interest for the economy.

It seems rather ridiculous to sum up the condition of the environment in
a single number. But this sort of thing has been tried. Google for
"Green GDP".

This has been attempted for different ecosystems. For example, RIVPACS and
BMWP scores have been used in the UK to assess the ecological condition of
rivers, based mostly on ecological indicators but RIVPACS also takes into
account geology, altitude, latitude etc.

However, I think you are possibly oversimplifying things by just saying 'the
environment'. The environment encompasses all of the biotic and abiotic
variables of whatever area you are interested in. It would make things
easier if you could more rigorously define what aspect of the environment
you are considering. At a guess, I think you are interested in the
ecological aspect of the environment. Whatever aspect it is, its not an easy
task. One area I have had some exposure to is the raft of recent European
Directives produced in response to several international summits such as Rio
and Ramsar. One particular directive that may help you is the Water
Framework Directive. This has the aim of assigning one of several ecological
conditions to aquatic environments, e.g. good, poor, based on various
indicators. That may show you how simple numbers or labels can be produced.
These labels however, are based on huge ecological datasets with mulitple
variates.

Hope that is of some use.
