The most vulnerable Australian landscapes to global warming driven sea-level rise are our low-lying coastal floodplains. Seawater inundation dramatically affects soil chemistry and water quality. Over 74,000 km2 of the low-lying coastal floodplains of Australia contain acid sulfate soils. For these soils, seawater inundation has the potential to greatly enhance the release of acidity, with a high capacity to severely degrade wetlands, estuaries and farmland. This project will directly contribute to our national capacity to assess and manage impacts from climate change, providing greater protection of our coastal floodplains resources.

最容易受到全球变暖驱动的海平面上升的澳大利亚景观是我们低洼的沿海洪泛平原。海水泛滥严重影响土壤化学和水质。澳大利亚74，000平方公里的低洼沿海洪泛平原含有酸性硫酸盐土壤。对于这些土壤，海水泛滥有可能大大增加酸度的释放，并有很大的能力严重退化湿地，河口和农田。该项目将直接促进我国评估和管理气候变化影响的能力，为我国沿海洪泛区资源提供更大的保护。
