hello out there!
first Switzerland & Germany, now Scotland! Where next will swarm go I wonder?
Here, in the land use & environmental modelling group at MLURI, we're trying to
model (& understand) the complex processes underlying rural land use change.
How do environmental, social and economic factors interact to affect this
change? How can employment, community and local ecosystems be conserved
harmoniously? (feel free to email me back on that one, if there are any
answers out there...)
Anyway, the project we're currently working on revolves around the alarming
decline in numbers of red grouse in this country. The management of these wild
birds has a large economic, environmental and social impact on rural areas over
here, something that their obstinate dive towards extinction is threatening.
So, we've been tasked with finding out more about how their population dynamics
are affected by enivironment and management changes. Unfortunately, the grouse
domain is very knowledge and data- poor (are all complex systems?). Also,
alot of the knowledge we have about it is diverse and conflicting. One of the
reasons for the conflicts, we believe, is that the knowledge gained from
different experts and empirical analysis is valid only in its own
particular ecological and management contexts.
For example, one of the many unsolved puzzles in this domain is what causes
grouse populations to cycle. There are two competing theories - parasites or
intrinsic factors based on kinship selection - both studied in isolation, both
claiming a degree of mutual exclusivity. Many research years have gone into
proving one or other invalid. But both of these can be effected by a whole
gamut of other factors (management options, predation, climate, etc.) as well
as each other.
What we want to try is integrating the A-Life simulation component of swarm
with a range of individual 'expert' knowledge bases to create a test bed for
investigating the conditions that may favour one particular theory or heuristic
over another. Different knowledge sources (e.g. expert 'Bob's encoded beliefs)
can have turns at defining how the simulation runs and results can be compared
against assumptions and hypotheses from other knowledge sources.
Hopefully swarm will give us the simulation flexibilty to investigate the
applicability of such ecological theories and heuristics not just in isolation
but also in the context of one or more interacting and possibly confounding
factors,including socio-economic considerations: How might the ecosystem and
management system feedback on each other?
Finally, the long term aim is to build a methodology for testing and augmenting
knowledge bases in a wide range of socio-economic/ecological domains.
Well, we're glad to be a part of it all and can't wait to get it up and running
to really understand all those problem reports people have been mailing in!
good luck everyone,
Matt Hare
