Dataset: Australian Dryland Salinity Assessment Spatial Data (1:2,500,000) – NLWRA 2001


The maps represent a compilation of dryland salinity risk and hazard mapping
for 2000, 2020 and 2050. The map shows the broad distribution of areas
considered as having either a high salinity risk or a high salinity hazard. In
southern Australia where groundwater level and trend data are available,
assessments that are more confident have been possible. However, in northern
Australia groundwater data for trend analysis are very sparse or non-existent.
In these regions, salinity assessments have been based on the presence of
geological, landscape, regolith, land use and climate attributes which are the
prime drivers of salinity. This national map provides a basis for identifying
those regions where more detailed assessments are warranted, and where land
use changes should be targeted if the risks are to be managed.The bulk of non-
agricultural areas in Western Australia, South Australia and western New South
Wales were considered to have a very low salinity risk and were not
assessed.Please note that the Commonwealth and all suppliers of source data
