Impacts of deforestation and afforestation on greenhouse gas emissions, and carbon and water resources in the Daly River catchment, north Australia. Over the last decade, north Australia have been viewed as a potentially exploitable resource, given issues of salinisation, soil acidification, over-allocation of water resources and rainfall declines in south Australian agricultural regions. Improved pastures and plantation forestry are two land uses that may expand in the NT.

Over the last decade, north Australia have been viewed as a potentially exploitable resource, given issues of salinisation, soil acidification, over-allocation of water resources and rainfall declines in south Australian agricultural regions. Improved pastures and plantation forestry are two land uses that may expand in the NT. Clearing of savanna vegetation would be required, with implications for greenhouse gas emissions, soil health, water resources and dry season environmental flows. This project will track greenhouse emissions and water use from uncleared and cleared savanna that has been converted to pasture and timber plantations, providing critical understanding of the environmental implication of such land use change in savanna.Read moreRead less
Non-CO2 greenhouse gas emissions in afforested ecosystems in southeastern Australia - fluxes, processes and regional budget. There are no data available about the extent of emissions of the non-CO2 greenhouse gases nitrous oxide and methane from soils of forest ecosystems in Australia and the current methodolgy to quantify these emissions contains high uncertainties. Using the latest technology available we propose to i) measure emission rates of afforested ecosystems for non-CO2 greenhouse gase ....Non-CO2 greenhouse gas emissions in afforested ecosystems in southeastern Australia - fluxes, processes and regional budget. There are no data available about the extent of emissions of the non-CO2 greenhouse gases nitrous oxide and methane from soils of forest ecosystems in Australia and the current methodolgy to quantify these emissions contains high uncertainties. Using the latest technology available we propose to i) measure emission rates of afforested ecosystems for non-CO2 greenhouse gases in relation to previous land-use in southeastern Australia, ii) identify the processes controlling the emissions, iii) use the obtained data to calibrate a biogeochemical model, and iv) use the model to estimate regional inventories for non-CO2 greenhouse gas emissions in southeastern Australia.Read moreRead less
