Environmental foresight and structural change. Environmental Modelling
Abstract: Policy-makers and the public, it has famously been said [Brooks, 1986], are more interested in the possibility of non-linear dislocations and surprises in the behavior of the environment than in smooth extrapolations of current trends. How indeed should we design our models to generate env...

Abstract: Policy-makers and the public, it has famously been said [Brooks, 1986], are more interested in the possibility of non-linear dislocations and surprises in the behavior of the environment than in smooth extrapolations of current trends. How indeed should we design our models to generate environmental foresight, to detect, in particular, threats to our environment lying “just beyond the horizon”? In facing this prospect of potentially profound dislocations in behavior, the problem is that the number of state variables in the model, whether they interact, how they interact, and the form of their interactions, may be evolving over time. What may have appeared to have been an insignificant mode of behavior in the past — buried within the uncertainty of the model and the historical data — may come to dominate behavior in the future. Technically, we may call this a change of structure.
