Auckland Regional Dynamic Ecological-Economic Model (ARDEEM)


ARDEEM is a dynamic simulation model of economic–environment futures for the Auckland Region.


ARDEEM is a system dynamics model designed to simulate the combined environmental and economic implications of change in the Auckland Region between 1998 and 2051. ARDEEM builds on the static monetary and physical flow models developed by McDonald and Patterson (1999), McDonald, Le Heron and Patterson (1999) and McDonald (2004a, 2004b, 2005). The model is characterised by positive and negative non-linear feed backs between its component modules. The purpose of the model is not to predict Auckland Region‘s economic future, but instead to highlight possible physical and economic consequences under various scenarios. A key reason for the adoption of a system dynamics modelling framework is that it allows a great deal of flexibility in setting the scenarios that may be investigated. The scenarios themselves are designed to capture not only the 'business as usual‘ situation, but also the dynamic physical and economic consequences resulting from more extreme change.
