Abstract
This paper explores some possible economic impacts of worsening salinity severity and extent in the grains industry across Australia. It also looks at the potential to increase agricultural profits through remediation. The analysis is based on a spatial model of agricultural profits and salinity related crop/pasture yield losses. It is estimated that grains industry farming profits across Australia would rise by an upper limit 138millionperyearweresalinitycostlesslyremovedfromthelandscape.Itisalsoestimatedthatthepresentvalueofgrainsindustryprofitlossesfromworseningsalinityextentandseverityoverthenext20yearsis237 million.
