[Taxacom] The Barometer of Life

Let me add other observations to decision making. That does not work in one person in a sensible way. Just think of smoking. So obviously we make 'wrong' decision though we have all the knowledge to make the right one. Well the wrong might be the right on some other level...

Further the guys doing the modeling and know everything about fish stocks, is not the customer, who things he is doing something good for himself eating fish... While depleting fish stocks... So good and bad a difficult concepts to grasp.

So 'absolute' knowledge does not make decisions better, actually to much knowledge might even prevent you taking decisions at all. Not quite the out come intended.

We had a CBD meeting recently here in Nairobi, and indeed they know that they cannot monitor everything, would not be useful, and feasible and again monitoring does not automatically trigger the biodiversity conserving decisions. Another matter is if the CBD is functional at all, or trying to do things it cannot do, since all the drivers of biodiversity loss, are by the structure of governments outside the Environment Ministries, such as traffic and agriculture and population growth. MoEs have little influence on other ministries and little legal leverage on customers...

Well it seems, one knows something, and the other does something else....

All the best nice start into the week!

Decisions are a different matter. But at least in the fisheres there are
fleets out there to study the fish populations. We do not have these tools
and instruments in place, such as the Biodiversity Monitoring System in
Switzerland (BDM-CH) that within 5 years surveys something like 2,500 plots
and thus can compare the data.

In this system there is a link from the observational data to the
conclusions. And no data has been collected randomly as almost all the data
is that goes into such tools as the Red Lists. This means, that there is no
definition of what the data means, nor does it allow running monitoring
program as is happening in the fisheries.

Even the Convention on Biological Diversity was specific that not all
biodiversity ought be monitored but those bits that are relevant.

What happened in the last twenty years was not the development of strategies
to monitor diversity beyond tiger and elephant, but always tools summarizing
data that in my view are not suitable from a scientific point of view to
make the bold statement being made with it. For a while, these statements
have been fine, but their value diminished as it does not provide the
necessary bases for land use and management.

Biodiversity is just one element that finally leads to policy decisions, and
thus better data is no guarantee for decisions in "our sense". But for me as
a scientist I do have the pretension that I want to have a system that lives
up to basic scientific principles, that is reproducibility and at least
openness to critique, and to use the best technology available.

Hi, guys.

Happy to continue this off-list while 'Objective Synonyms' rages.

A great example I can give you of the disconnect between knowledge and
decision-making is wild fishery management. Decades of research, millions of
research vessel hours, good hard catch data, sophisticated modelling, global
discussions on total allowable catch. With what result? Fishery after
fishery collapsing from overfishing. We *know* we're stuffing the wild
fisheries, we're doing it anyway because fish are food and there are more
and more people wanting them and willing to pay for them.

*Do* read Glovbal Biodiversity Outlook 3. It's scary as hell.
