could be a problem still happening.
Quote:.............Impacts by state[edit]
New South Wales[edit]
Currently 5% of New South Wales is affected by dry land salinity, and around 50% is under threat.[9] 15% of current irrigated land is impacted, and up to 70% is currently under threat.[9] The main regions currently affected, and at high risk, are The Murrumbidgee River catchment near Griffith, and Jemalong River Catchment near Forbes, as well as the Murray River irrigation area near Deniliquin.[9]
Victoria[edit]
The current levels of salinity in Victoria are relatively small, with the main impact expected to occur in high risk areas in the coming years. These high risk areas include the Campaspe, Loddon, Corangamite, Glenelg-Hopkins, Goulburn-Broken catchments, and Wimmera and Mallee regions.[10] The current cost to Victoria is estimated at $50million per year. This is expected to rise significantly with the impacts on agricultural land, wetlands and infrastructure in high risk areas to increase, mainly in part to an anticipated 10 fold increase in salt levels by 2050.[9]
Western Australia[edit]
Western Australia contains the majority of land affected by salinity in Australia, with around 70%. Over 2 million hectares are currently affected, and around 4 million hectares of land are currently listed as high risk, and 50% of divertible water is already considered overly saline.[9] Around 450 plant species are endemic to areas that are at high risk of salinisation[11] 75% of water bird species in decline, a 75% reduction in sealed road life, and $400million in lost profits.[9]
South Australia[edit]
Salinity in South Australia is a problem in all principal agricultural areas, with 370000 hectares of land and wetlands impacted. At current rates, this is expected to increase by 60% by 2050.[12] It is expected to cost the state around $47million per year in lost agricultural profit, and is expected to taint more than 20% of ground water to levels above those safe for human consumption.[9]
Tasmania[edit]
Tasmania is relatively unaffected by salinity, with around 1% of agricultural land, and 8% of farm land adversely affected by salt, resulting in a current cost to the state of around $5million per year, rising to around $13million by 2050. The majority of this salinity is irrigation based.[9]
Queensland[edit]
Queensland is the least affected state of Australia, due to its unique seasonal rainfall. Around 15000 hectares are currently affected, with 3.1million hectares considered highrisk.[9] At current rates however, salinity is predicted to have moderate scale impacts on land and infrastructure by 2050, with 12,000 km of roads, 1500 km of rail lines, and around 2.8million hectares of agricultural land, remnant vegetation, and wetlands and streams negatively affected[13]............
............. The final report for the NAPSWQ states that ‘With few exceptions the massive efforts involved in delivering NAPSWQ and NHT programs have at best halted the degradation of these resources. This has reinforced the view of the State of Environment (SoE) Report that concluded that the condition of these resources continues to decline despite the best efforts of the community and government'.[18].............
