This project aims to investigate how plant litter breakdown in wetlands controls soil carbon preservation by identifying the climatic, environmental and microbial drivers of decomposition on a global scale. This project will generate new knowledge in the area of freshwater and coastal wetland ecology using interdisciplinary approaches in biogeochemistry and microbial ecology. Outcomes of this project include novel global datasets that will identify why some wetlands preserve carbon better than others and what management practices can enhance sequestration capacity. This should provide significant benefits, including advancing carbon-cycling models and predictions, and improving capacity to manage and restore wetland function.Read moreRead less

Optimal management of coastal ecosystems for blue carbon sequestration. This project aims to develop decision tools to predict how different management plans could affect the persistence of coastal ecosystems and their capacity to sequester carbon. Coastal ‘blue carbon’ ecosystems (seagrasses, saltmarshes, mangroves) are among Earth’s most efficient carbon sinks, but coastal development and climate change threaten their capacity to sequester carbon. Resource managers urgently need guidance to manage coasts to minimise carbon losses and maximise gains. This project is expected to develop knowledge of how to manage blue carbon ecosystems to achieve maximum carbon sequestration capacity, and to put Australia at the forefront of international efforts to incorporate coastal carbon within carbon dioxide mitigation strategies.Read moreRead less

Some lakes, such as the Coorong lakes in South Australia, naturally sequester carbon dioxide in magnesium carbonate minerals. These minerals, which form in association with microorganisms in lake water, represent the safest possible long-term traps for carbon dioxide pollution. This project aims to determine the essential geochemical constraints on formation of magnesium carbonate minerals in the Coorong lakes, which are unique natural laboratories for studying carbon dioxide sequestration. By delivering fundamental understanding of how microbial populations alter water chemistry for carbonate production, this project aims to inform the design of efficient and sustainable technologies for carbon dioxide sequestration that emulate natural processes in lakes.Read moreRead less
