Requests for paper on "economic value of corals - 10 years on"

Dear Listers
Many apologies for having to respond via the coral list, but I am currently
working in Kazakhstan (developing a GIS based water resources optimisation
model), and sending emails takes forever.

I will send the pdf to all those requesting it when I return to the UK in 2
weeks.  For those who asked, it cannot be downloaded from a web site, and I
don't know the size of the file.

For those interested, the Kazak approach for increasing the carrying
capacity for swimming in rivers at the moment (eg last weekend when it was
-26C), is to simply make the holes in the ice bigger.  There is little need
to restrict how long people stay in the water!

Best wishes
James

I am interested in a pdf copy of Spurgeon J. (2001) "Economic Value of
Coral Reefs: The Next Ten Years"

Thanks in advance.

Dear Pedro and listers

The visitor "carrying capacity" of a coral reef is a function of the
following factors:

·Number of people entering the water
·*Means of accessing the water (anchoring, shoreline, boardwalks etc)
·*Activity they undertake (diving, snorkelling, with gloves etc)
·*Visitor experience, training and education
·*Management tools (fines, visitor facilities, restricting access etc)
·Natural physical conditions (depth, topography, currents, waves, etc)
·Type of corals (form and fragility)
·*Extent of other stresses (wastewater, sea temperature etc)
·*Levels of acceptable change (extent of acceptable coral cover etc)

Consequently, reef carrying capacities will differ enormously (and
Duncan's
point is certainly valid).  However, for management purposes,
generalizations could be made for several different categories of reef.

Furthermore, because several factors* can be modified, carrying capacity
at
any site can be changed significantly. Note that in the Galapagos
Islands, a
maximum carrying capacity of 20,000 visitors per year was set in 1985.
Currently, over 65,000 people visit each year.  Through various
management
measures, associated visitor damage is minor, especially compared to
other
stresses (e.g. introduction of domestic animals).

I've not seen Jamie Oliver's paper, but "limits of acceptable change" is
a
great concept if you are confident of the cause-effect relationships.
This
is more the case for terrestrial systems than marine.  LAC also requires
legislation and management controls strong and flexible enough to allow
effective and timely changes in management.

Controlling visitor numbers also does significantly affect potential
economic, financial and social benefits. For many asscociated reasons it
will be better to build up capacity cautiously over time!

All these issues are being explored in some current/proposed research:
Spurgeon, J. (in prep) "Maximizing benefits and revenues from coral reef
management", hopefully culminating in a paper to be presented in Japan.
In
the near future I'll be looking for partial funding and additional
materials
to draw upon.  Offers for either would be greatly appreciated!

In addition to those who requested it a while ago, anyone wanting a pdf
copy
of Spurgeon J. (2001) "Economic Value of Coral Reefs: The Next Ten
Years",
let me know.
