Greenhouse gases threaten the global climate. Many estimates of vegetation as sinks and sources for greenhouse gases have a high degree of uncertainty. This project will generate important information about greenhouse gas emissions from Queensland coastal vegetation. Characterised by moist and nutrient rich conditions, sugarcane fields and mangrove ecosystems represent significant sources/sinks of potent greenhouse gases nitrous oxide and methane. Sugarcane and mangroves exposed to different nutrient inputs will allow to (i) identify mechanisms of N2O and CH4 emission, (ii) model N2O and CH4 emissions under different nutrient and climate conditions, and (iii) control/reduce emissions by improving coastal ecosystem management.Read moreRead less

The project demonstrates how evaluation can lead to improved management of protected areas. Effectively managed protected areas are essential for biodiversity conservation. Improved management, and hence improved conservation outcomes will flow from enhanced use of monitoring and evaluation data in decision-making. Identifying strengths and weaknesses in management will allow managers to better allocate resource for more effective conservation outcomes. The project establishes connections with all protected area management agencies in Australia, and will contribute to the development of national policy and practice in protected area evaluation and reporting, thus helping to meet national and international reporting obligations.

Maximising the conservation of biodiversity and the delivery of ecosystem services: What to do, where and when. The economic wealth of Australia is underpinned by its remarkable biological diversity. However, land and water degradation are eroding Australia's natural asset base damaging industries such as tourism, fisheries, and forestry. Given limited funds for biodiversity conservation, we need to minimise the misallocation of resources by making wise investments. This research will result in ....Maximising the conservation of biodiversity and the delivery of ecosystem services: What to do, where and when. The economic wealth of Australia is underpinned by its remarkable biological diversity. However, land and water degradation are eroding Australia's natural asset base damaging industries such as tourism, fisheries, and forestry. Given limited funds for biodiversity conservation, we need to minimise the misallocation of resources by making wise investments. This research will result in frameworks and tools to ensure that we maximise the protection of biological diversity and the delivery of ecosystem services (such as clean water) that are important for human well-being. We will share the results of our research with decision makers, scientists, and the general public.Read moreRead less
Transformations of catchment nutrients in southeast Queensland. Human activity in catchments throughout southeast Queensland has increased nutrient loads in receiving waters. However, until recently there has been a lack of accurate quantification of these loads, and little understanding of their role in stimulating algal blooms. This proposal will examine the links between catchment nutrient inputs to waterways, their transformations and effects on stimulating algal growth in freshwater systems ....Transformations of catchment nutrients in southeast Queensland. Human activity in catchments throughout southeast Queensland has increased nutrient loads in receiving waters. However, until recently there has been a lack of accurate quantification of these loads, and little understanding of their role in stimulating algal blooms. This proposal will examine the links between catchment nutrient inputs to waterways, their transformations and effects on stimulating algal growth in freshwater systems. The outcomes from this research will be information on how catchment nutrients are affecting water quality, thus providing a vehicle for targeting management strategies designed to reduce nutrient loads.Read moreRead less
Farmer Adoption of Sustainable Land Management Practices in the Fitzroy Basin, Central Queensland. The research project will identify the barriers to, and facilitators of, the adoption of sustainable land management practices in the grazing industry in the Fitzroy Basin, Central Queensland.

The research project will identify the barriers to, and facilitators of, the adoption of sustainable land management practices in the grazing industry in the Fitzroy Basin, Central Queensland. Current agricultural extension approaches to environmental innovations in grazing have been criticised for their inability to facilitate rapid implementation of necessary on-ground changes. This research is significant in identifying key socio-economic and environmental factors that need to be considered in developing regional policy approaches to sustainable agricultural development. Outcomes will include better uptake of environmental measures by graziers and policy advice to government and industry on sustainable development options.Read moreRead less
A Fundamental Understanding of Methane Driven Denitrification. Eutrophication in waterways due to the presence of nutrients including nitrogen is a well-recognised environmental problem. Moreton Bay, for example, used to receive 3,300 tons of nitrogen each year from point sources. Stringent nitrogen discharge limits have therefore been imposed on most wastewater treatment systems across Australia. Nitrogen removal from wastewater is commonly accomplished in a biological way involving the use of ....A Fundamental Understanding of Methane Driven Denitrification. Eutrophication in waterways due to the presence of nutrients including nitrogen is a well-recognised environmental problem. Moreton Bay, for example, used to receive 3,300 tons of nitrogen each year from point sources. Stringent nitrogen discharge limits have therefore been imposed on most wastewater treatment systems across Australia. Nitrogen removal from wastewater is commonly accomplished in a biological way involving the use of bacteria. The project aims to investigate a particular bacterial community, which is able to perform nitrogen removal from wastewater with methane as a renewable carbon source. The project will therefore lead to more sustainable wastewater treatment systems.Read moreRead less

Nitrogen removal from wastewater is essential to protect our unique aquatic environment. This removal is typically achieved via two steps: Nitrification converts ammonium via nitrite to nitrate; denitrification converts nitrate via nitrite again to harmless nitrogen gas. This project will develop a biofilm reactor system, which enables this process to run via nitrite only, instead of nitrate. Savings of 40% carbon and 25% oxygen requirements are possible this way. This process has not yet been demonstrated under controlled conditions, but recent progress in the research groups in Australia and Korea now offer novel ways to accomplish this promising process.Read moreRead less
