Explaining forest responses to rising carbon-dioxide concentrations at stand scale using a new, simple model of plant carbon economy. Australia is undergoing large changes in [CO2] and rainfall patterns, with 20% decreases in annual rainfall across southern Australia over the past 30 years, and large increases in north-western Australia. The impacts of rising [CO2] and altered rainfall must be factored into Australia's environmental and water-catchment management strategies. The outcome of this ....Explaining forest responses to rising carbon-dioxide concentrations at stand scale using a new, simple model of plant carbon economy. Australia is undergoing large changes in [CO2] and rainfall patterns, with 20% decreases in annual rainfall across southern Australia over the past 30 years, and large increases in north-western Australia. The impacts of rising [CO2] and altered rainfall must be factored into Australia's environmental and water-catchment management strategies. The outcome of this project will be a new simplified forest model that has been validated for Australia's leading climate-change experiment on forests, the Hawkesbury Forest Experiment, which includes both CO2 and watering treatments. The model will be readily transferable to new sites and at regional scale, so it can be applied as a tool for future management of Australia's forests.Read moreRead less
Reducing uncertainties in greenhouse gas emissions from sub-tropical land use systems. The principle outcome of the research is the identification of sustainable land use management strategies that will ensure the continued productivity and profitability of food and fibre in the Australian sub-tropics and tropics in response to climate change whilst reducing greenhouse gas emissions. Regional communities will benefit through a greater awareness of emission sources and sinks and exposure to viabl ....Reducing uncertainties in greenhouse gas emissions from sub-tropical land use systems. The principle outcome of the research is the identification of sustainable land use management strategies that will ensure the continued productivity and profitability of food and fibre in the Australian sub-tropics and tropics in response to climate change whilst reducing greenhouse gas emissions. Regional communities will benefit through a greater awareness of emission sources and sinks and exposure to viable and practical strategies that promote productivity through regional diversity in land use. Improved data on greenhouse gas accounts will also ensure the Australia community is provided with full and accurate representation in international climate change fora and policy development.Read moreRead less
