models of forests and forest economies

["Bob Cavana"]

hi Andrew

sorry i havent replied to this earlier but i have been out of town
a lot lately

i did my PhD research at the University of Bradford Management Centre
with Prof Geoff Coyle in the early 80s and the following were produced :

Cavana, R.Y. 1983. Managing the Plantation Forests in New Zealand: a
system dynamics study in the design of robust policies...
Unpublished Ph.D. Thesis. University of Bradford, England. 400pp

Cavana, R.Y. and R.G. Coyle. 1984. A Policy Analysis Model for New
Zealands Plantation Forestry System. N.Z. Journal of Forestry. 29(1).
pp24-50

Geoff Coyle refers to this work in his recent book (in Chapter 10, pp
309-314). Also a full listing of the model is provided on the
computer disk with his book:

R.G.Coyle (1996). System Dynamics Modelling: a practical approach.
Chapman Hall, London

Our work at Bradford developed from my earlier collaborative work between
the NZ Forest Service & the NZ Ministry of Works, which was a initial
attempt to look at the regional economic impacts of forestry. the
following working paper was produced:

Grant, H.E., A.W. Smith, A.M. Bartlett, R.Y. Cavana and K.D. Lowen.
1979. A Users Guide to the MWD Forestry Model. Development and
Programming Branch, Ministry of Works and Development, Wellington.
33pp

however our Bradford work was more concerned with forestry policy &
management rather than the linkages between forestry & the economy

we found the earlier work by Jorgen Randers et al (1979) and Steven
Boyce (1977, 1979, 1980) very helpful for our research:

Randers, J., L.Stenberg & K.Kalgraf (1979) The forest sector in
transition, Resource Policy Group, Oslo, Norway (GRS 93E3)

Boyce, S.G (1977) Management of Eastern Hardwood forests for multiple
benefits (DYNAST - MB). USDA Forest Service, Southeast, For.Exp.Stn,
Asheville, NC, USA (USDA For serv res papers, SE - 168 (in 1977) ,
SE-184 (in 1978), SE - 204 (in 1980)

i hope these sources are useful. please contact me if i can be of
further assistance.

we also hope you will prepare a paper on your work and present it at
the next International System Dynamics Conference to be held in
Wellington, New Zealand on 2--24 July 1999 !

i would be delighted to meet you and your colleagues and discuss
forestry SD modelling in depth with you

Dear System Dynamicists:

Don Seville and I are working with Dana Meadows on the Commodity Systems
modeling project of the newly-formed Sustainability Institute. We are
seeking system dynamics models that investigate:

1. the dynamics of forests, and/or
2. the interactions between forest ecosystems and regional economies

The models could focus either at the detailed/policy-analysis level or more
demonstration/teaching level.

We are following leads from the SD Bibliography, but now seek guidance from
the SD network. Do you have any suggestions for us?

Thank you very much for your help.

Sincerely,

Drew Jones

You might wish to check the CIFOR Web Page (Center for International
Forestry Research) at http://www.cgiar.org/cifor/index.html.

I believe that they are doing some work along these lines under a
programme called "flores".

This is a reply to Drew Jones posting, and is only offered because Drew
is such a terrific SDer and should be setting the pace for the rest of
us!

Drew: Shouldnt you have specified the reference mode(s) of interest to
the project?
