Forecasting soil conditions. Not knowing where and how soil responds to climate change and human intervention compromises food, water, climate and energy security. Currently there is a lack of soil process knowledge and data infrastructure collectively causing significant uncertainty and risk in the assessments of key threats to soil.

Not knowing where and how soil responds to climate change and human intervention compromises food, water, climate and energy security. Currently there is a lack of soil process knowledge and data infrastructure collectively causing significant uncertainty and risk in the assessments of key threats to soil. The project devises a transformational digital soil model to forecast where and how soil pH and carbon will change in New South Wales. Tested on sites within Australia, the model will give insight on the drivers of change and will provide a unique analysis of the effect of climate change and land management on the dynamics of soil.Read moreRead less
Dynamic soil landscape carbon modelling. Soil is the largest terrestrial store of carbon. This project will enhance our understanding of the causes and controls of spatial and temporal variations of soil carbon which is crucial for managing climate change, food water and energy security and for maintenance of biodiversity.

Synergising pedodiversity and biodiversity to secure soil functionality. This project aims to understand the coupling between soil physical, chemical and biological diversity at a range of scales and land uses across New South Wales and its relationship with soil functioning.

This project aims to understand the coupling between soil physical, chemical and biological diversity at a range of scales and land uses across New South Wales and its relationship with soil functioning. Soil diversity with its coupled biodiversity is crucial for conservation of sustainable ecosystems. Soil diversity varies on a continuum from microbial habitats to elds, catchments and regions. This project will enhance our ability to understand the drivers of soil change through time, critical for minimising loss of biodiversity, achieving food and soil security and inferring effects of climate change.Read moreRead less
Carbon in - carbon out: can carbon inputs keep up with losses in peatland? This project aims to quantify the current and predict the future carbon balance of a high altitude, carbon-dense ecosystem, namely sub-alpine grassy peatland, by measuring how environmental variables including experimental warming control the fluxes of carbon and water into and out of the system. In this way, this project will produce new knowledge on the susceptibility of high-altitude peaty soils to climate change. Expe ....Carbon in - carbon out: can carbon inputs keep up with losses in peatland? This project aims to quantify the current and predict the future carbon balance of a high altitude, carbon-dense ecosystem, namely sub-alpine grassy peatland, by measuring how environmental variables including experimental warming control the fluxes of carbon and water into and out of the system. In this way, this project will produce new knowledge on the susceptibility of high-altitude peaty soils to climate change. Expected outcomes include an enhanced ability to predict future carbon accumulation rates and the resilience of the vital water-storage and filtration services provided by these systems. This project will enhance outputs from new infrastructure and assist planning for future flood and drought management across SE Australia.Read moreRead less
Carbon conundrum: Functional characterisation of organic matter-clay mineral interactions in relation to carbon sequestration. Carbon sequestration in soil has been recognised as one of the possible measures through which greenhouse gas emissions can be mitigated. The major processes involved in carbon sequestration in soil include chemical immobilisation of carbon with soil particles and physical protection in the pores of soil microaggregates. These two processes are mediated through the funct ....Carbon conundrum: Functional characterisation of organic matter-clay mineral interactions in relation to carbon sequestration. Carbon sequestration in soil has been recognised as one of the possible measures through which greenhouse gas emissions can be mitigated. The major processes involved in carbon sequestration in soil include chemical immobilisation of carbon with soil particles and physical protection in the pores of soil microaggregates. These two processes are mediated through the functional relationships of soil organic matter and clay mineral interactions in soils. This project investigates nanoscale organomineral association underlying microaggregate formation and stability, as well as the distribution and microbial decomposition of carbon within microaggregates using a suite of advanced spectroscopic, molecular and isotopic techniques.Read moreRead less
Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An ....Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An aim of management is to identify fire regimes that will optimise the carbon outcome as well as provide protection to life and property. This project will help managers meet that aim by developing a quantitative understanding of how much stable, black carbon (charcoal) is produced and how it affects other soil processes.Read moreRead less
Unlocking the anchors of soil organic carbon to manage climate change. Soil is the largest reservoir of terrestrial organic carbon. Most of the organic carbon in soils is preserved by association with minerals, however, the composition and stability of mineral-associated organic carbon remain poorly understood. The project will use novel and emerging techniques to discover the composition of organic carbon and stability of organic carbon present in mineral-organic associations in representative ....Unlocking the anchors of soil organic carbon to manage climate change.

Unravelling soil carbon response to warming in fire-affected ecosystems. This project aims to reveal the continental pattern of soil carbon (C) response to warming in fire-affected ecosystems across Australia and to unravel the biogeochemical mechanisms underlying fire’s role in shaping the temperature sensitivity of soil respiration. Fire has modified over 40% of the Earth’s land surface and wildfire frequency is predicted to increase under global warming. This project expects to generate new k ....Unravelling soil carbon response to warming in fire-affected ecosystems. This project aims to reveal the continental pattern of soil carbon (C) response to warming in fire-affected ecosystems across Australia and to unravel the biogeochemical mechanisms underlying fire’s role in shaping the temperature sensitivity of soil respiration. Fire has modified over 40% of the Earth’s land surface and wildfire frequency is predicted to increase under global warming. This project expects to generate new knowledge on how fire influences soil-to-atmosphere C fluxes in a warmer climate using a multi-disciplinary approach. Expected outcomes include an enhanced capacity to predict the terrestrial ecosystem-to-atmosphere C fluxes and their feedbacks to climate under increasing frequency of fire using Earth-system models.

The aim of this project is to investigate carbon burial in mangroves during current and historical climatic conditions through in depth dating methods and paleoclimate reconstructions. The project intends to use state-of-the-art radionuclide tracer technologies to determine system scale aspects of the mangrove carbon budget, i.e. burial, tidal export and respiration. This project is significant because it aims to delineate how climatic conditions are directly related to the mangrove carbon budget. Further, the site specific data on historical mangrove carbon burial could allow adaptation strategies for use of coastal wetland habitats that sequester CO2, a natural means to help ameliorate greenhouse gas, as support for mangrove forest protection and restoration.Read moreRead less
