Derived map of salinity hazard, with mapped salinity (Furby et al., 2009) overlaid, for the southwest agricultural region and (insert) for an approximately 16 km2 subregion showing the mapping detail (near Lake Magenta). Areas mapped as salt affected in 1988 are shown in orange. Areas that became salt affected by 1998 are shown in red. The salinity hazard areas are shown in blue. The greyscale background is a January 1994 Landsat TM mosaic image. The green square in the main display shows the location of the insert region.
