In the Murray River valley irrigation has caused salinity problems. Land surrounding the town of Werrimull in the northwest of Victoria have been affected by salinity due to land clearing.he Eastern Mallee and the Western Mallee of Western Australia are areas that are prone to salinity with little remedial action being undertaken to rectify the problem. Lands surrounding Lake Bryde-East Lake Bryde and Dumbleyung Lake have also been affected.
More than half of the dry areas worldwide are. affected by land degradation (Dregne and Chou, 1994). Although water erosion is the. dominant human-induced soil degradation process, an extent of 0.8 million km2 suffers from. secondary salinization caused by land mismanagement, with 58% of these in irrigated areas. alone, and nearly 20% of all irrigated land is salt affected (Ghassemi et al ., 1995).
