ABSTRACT
The final section of this text will pull together the story line that has been introduced in the previous four chapters and will consider how computer based models can be used to represent that story in a way that is policy relevant. Methodologically this section will also highlight the need to integrate different types of model which represent data at varying levels of resolution. The data used for the models reported in the following chapters refers to the research phase ending in 1994. Whilst this means that more recent events such as the increase in rainfall and aquifer replenishment will not be represented, the techniques employed remain relevant
This chapter will present a model of crop choice and chapter eleven will describe the background to modelling the water/salt system. Ongoing attempts to develop an integrated strategic representation of the system will then be presented and a concluding discussion will consider the policy and methodological implications of the work. More specifically the tasks in this chapter are:
I. to contribute to an improved understanding of the linkages between policy instruments and the receptivity of farmers to these.
