Seeing the good from the trees: remotely sensing the urban forest. Urban forests provide a range of ecosystem services including temperature regulation and rainfall capture, but measuring these benefits is currently prohibitively costly and inaccurate. This project aims to develop a new model of urban forest ecosystem services that uses remotely sensed three dimensional data to map canopy cover. A model using this data, which is being collected by an increasing number of governments, represents ....Seeing the good from the trees: remotely sensing the urban forest. Urban forests provide a range of ecosystem services including temperature regulation and rainfall capture, but measuring these benefits is currently prohibitively costly and inaccurate. This project aims to develop a new model of urban forest ecosystem services that uses remotely sensed three dimensional data to map canopy cover. A model using this data, which is being collected by an increasing number of governments, represents a novel advance on the established methodology that requires expensive and time-consuming fieldwork. The advancements expected to be made in this project will mean that environmental planners will be able to better plan the urban forest so that cities are more liveable and resilient in the face of climate change.Read moreRead less
Assessing soil formation and erosion balances in the Top End with an expanded toolkit. This work is timely as it will provide the tools and the data to assess the sustainability with regard to soil loss of potential agricultural development in the Top End of Australia.

This work is timely as it will provide the tools and the data to assess the sustainability with regard to soil loss of potential agricultural development in the Top End of Australia. With food-growing areas in southern Australia under stress from a prolonged drought, the Federal Government has established a Northern Australia Land and Water Taskforce to explore the potential of the Top End for agricultural and other development. A key component of its brief is that development must be sustainable. The economic consequences of increased agriculture in the North are likely to be profound, and the findings of this research will be crucial to success.Read moreRead less
Developing new techniques for mapping soil loss and movement in Australia. Soil erosion is a major problem for Australia. This project will develop and test a new and sensitive method to quantify soil loss and measure soil erosion and transport, using cutting-edge technologies conceived and developed in Australia.
Production and transport of soil and sediments, determined by cosmogenic radionuclides and noble gases. Basic questions concerning Australia's soil and regolith resources are addressed through measurement of nuclides produced by cosmic rays in near-surface minerals. Cosmogenic Be-10, Ne-21 and Al-26 are used to (i) quantify the sustainable levels of soil loss, (ii) assess long-term mixing rates, (iii) quantify dispersion and flux of regolith materials from hill-slopes to rivers, and (iv) determi ....Production and transport of soil and sediments, determined by cosmogenic radionuclides and noble gases.

The research has strong implications for the usage and conservation of soil, sediments and weathered deposits for agriculture, mineral resources, and sedimentary waste disposal.Read moreRead less
Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity a ....Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity around the Bay. While dredging and on-land treatment of sediments is being adopted at the most severely contaminated sites, the cost of this approach is exorbitant. For sites where removal of contaminated sediments cannot be justified, the approach proposed in this study of a technology that entraps contaminants and enhances their in situ biodegradation is potentially a way forward.Read moreRead less

Soil Acidification, the Environment and Production. Soil acidification affects 50% of Australia's agricultural land and is the most important economic constraint to agricultural. In addition, major external offsite impacts include greenhouse gas emissions, reduced stream and ground water health, reduced biodiversity, increased salinity and waterlogging and infrastructure damage. The aim of this network is to quantify the acidification processes and the connection of these processes to the offsit ....Soil Acidification, the Environment and Production.

In addition, major external offsite impacts include greenhouse gas emissions, reduced stream and ground water health, reduced biodiversity, increased salinity and waterlogging and infrastructure damage. The aim of this network is to quantify the acidification processes and the connection of these processes to the offsite impacts. This will lead to development of strategic plans for acidified and potential acid soils and associate offsite impacts, as well as identifying knowledge gaps and building research and policy synergies.

Focussed on the 40,000 years of human presence, the research is an integrated approach to changes of earth systems in the Australian region.The equipment is a single-stage accelerator mass spectrometer (SSAMS) with an innovative gas-fed ion source and automated gas-handling system, with simpler processing and smaller samples than present AMS facilities. Future developments include automated multi-sample handling and coupling to microprobe and chromatographic analysers for microscale radiocarbon analysis of complex substances.Read moreRead less
