Use of Distichlis spicata for sustainable forage production on saline land to manage dryland salinity. Sustainable and productive use of salt-affected lands is a priority for many farmers. This project aims to develop management strategies that optimise yield, water use and nutritive value of Distichlis spicata (a salt-tolerant grass) forage on salinised lands, and to understand how this forage species affects the salt cycle, water use and fertility improvement of saline soils.
Environmental risk assessment of acid sulfate soil formation and pollutant generation in Swan Coastal Plain. The urgency and importance of securing water sources for human use in a sustainable manner is dictated by drying climate and rapid population expansion in Australia. Dropping groundwater levels (less recharge, increased abstraction, enhanced drainage) result in formation of acid sulfate soils in oxidised layers that contain acid-bearing minerals. This project will produce an environmental ....Environmental risk assessment of acid sulfate soil formation and pollutant generation in Swan Coastal Plain. The urgency and importance of securing water sources for human use in a sustainable manner is dictated by drying climate and rapid population expansion in Australia. Dropping groundwater levels (less recharge, increased abstraction, enhanced drainage) result in formation of acid sulfate soils in oxidised layers that contain acid-bearing minerals. This project will produce an environmental risk assessment framework as a basis for (i) educated decisions regarding land development and soil disturbance vs conservation as well as (ii) identifying areas suitable for water abstraction from groundwater resources. This will ensure sustainable use of precious groundwater resources in this drying continent of ours.Read moreRead less
