Following on from the
UVA Bay Game post I thought it was about time to blog about
Cormas and the
ComMod (Companion Modeling Approach) which focus on participatory agent-based modeling for resource management.
Why the interest? Take ecosystem management as an example, there are often many actors (stakeholders) who influence and control ecosystem management. For example, in the
Chesapeake Bay there are farmers, local policy-makers, watermen, and developers. Such stakeholders have many different goals, associated feedbacks, negotiations etc... The question is how does one build models of such interactions?
Often when we build models of such interactions we do not always engage with stakeholders directly. Participatory modeling approaches such as companion modeling offers one way for such engagement. It uses various techniques, including role playing games in the sense that models are built with the direct involvement of stakeholders. Where modelers develop and validate model rules in conjunction with those one is modeling. Such a direct involvement of stakeholders focuses our attention on how decisions are made and what are the problems rather than just simulating the effects (e.g. Gimblett et al., 2002).
This brings me back to the
ComMod approach and
Cormas (an agent-based simulation framework, often used in conjunction with the ComMod approach). In the sense that ComMod is a iterative modeling process from the “bottom up.” ComMod provides an endless cycle of "field work and data analysis -> role playing games -> agent-based model development and implementation -> simulation -> field work again (Barreteau, 2003) as depicted below:
