Efficiency Policies for Salinity Management: Preliminary Research from a Spatial and Dynamic Metamodel

Dryland salinity, as an externality, has an impact on various public assets, including roads,biodiversity and public water supplies. This has been seen as an important justification forgovernment to take action and internalise the pollution. Economic policy instruments have beenidentified as a potential solution to the problem, as they may achieve environmental goals at leastcost to society. This paper presents a spatial and dynamic model which aims to compareeconomic instruments for land use change to abate the off-site impacts of salinity on publicassets. Preliminary research is presented, along with a discussion of the model’s structure.
