Increasing salinity is one of the most crucial environmental problems facing Australia. Dryland salinity isn’t only a rural and environmental problem; it is increasingly an urban problem. Millions of hectares of land across Australia are becoming more and more difficult to use because of the salt that has been brought to the surface. ... If nothing is done then Australia will only get saltier.
While salt is naturally present in many of our landscapes, European farming practices which replaced native vegetation with shallow-rooted crops and pastures have caused an increase in the appearance of salinity in our land and water resources. ... The rising water tables are also affecting our rural infrastructure including buildings, roads, pipes and underground cables. Salinity and rising water tables incur significant and costly impacts. ...
(See “The Effect of Vegetation Clearance on Watertables” in appendix)
The impacts of salinity are separated both in time and space from its causes. This means that while Australia’s salinity problem is already significant, it is expected to increase as a result of past and present practices. ...
Dryland salinity can lead to lower agricultural production, lower profitability due to costs of mitigation, reduced yield, changed land use, and in extreme cases to the total removal of land from agricultural production.
