Systems framework for regional-scale integrated modelling and assessment

Computer-based methods of integrated modelling and assessment provide an important means for reviewing policy choices in natural resource management (NRM). Research in support of NRM needs to address a wide range of issues involved, from point-scale biophysical, to business-scale human, to regional-scale planning issues. Research covering the full scope of such issues is by default multi-disciplinary and integrative and therefore analytically, methodologically and operationally challenging. The recently initiated Ord-Bonaparte Program is an example of a research and development program attempting to achieve both levels of integration in an applied NRM context. One key requirement for the success of the program lies in developing a systems framework that: (i) enables the integration of the various disciplinary research activities; and (ii) facilitates the implementation of research outputs by making integrated science relevant to decision-makers and translating new knowledge into outcomes for sustainable regional development. This paper proposes an approaches for such a systems framework. (C) 2003 IMACS. Published by Elsevier B.V. All rights reserved.
