The main drivers of change to natural resources identified in the Northern Murray Mallee subregion are:
- access to export and domestic markets
- markets and commodity prices
- climate change and seasonality of rainfall
- corporatisation of farms and increasing economies of scale.
Potential natural resource impacts of climate change projections in the Northern Murray Mallee subregion include:
