Abstract

Interactions between biophysical constraints and land use in the rainfed cropping systems of southwest Australia were investigated by two methods. First, literature review provides a brief historical outline of the development of rainfed crop and pasture systems of southwest Australia, establishing instances of causality between biophysical constraints and land use. Secondly farm survey data from southwest Australia were used within the research chapters to examine dynamics of constraints; including weeds, nutrients and soilborne plant pathogens in the context of current rotations, and identify which constraints were limiting water use efficiency of wheat over the period 2010–2015.
