An integrated modelling approach to balancing trade-off issues in natural resource management

Abstract

The south-west region of the Goulburn-Broken catchment (SWG) in northern Victoria is facing a range of natural resource challenges. High salt load export from the region affects water quality and contributes to stream degradation in the Murray River system. Traditionally, salinity management strategies have focused on increasing plant water use (e.g. tree planting). In recent years, however, there has been growing concern that the prevailing dry climatic conditions and revegetation are threatening the water supply and health of ecosystem. In this context, it will require a flexible and carefully balanced strategy to achieve the contrasting objectives of remediating land salinisation and redu..
