Up in smoke and out to sea? Carbon, water and land use change in savanna. This project aims to improve our understanding of carbon cycling in natural and transformed savannas. It seeks to resolve a large discrepancy in savanna carbon sink size as measured by flux towers compared to long-term direct measures of carbon stock change. This would improve our fundamental understanding of carbon balances (gains/losses) and residence times in these dynamic ecosystems. The long-term impacts of these land ....Up in smoke and out to sea? Carbon, water and land use change in savanna. This project aims to improve our understanding of carbon cycling in natural and transformed savannas. It seeks to resolve a large discrepancy in savanna carbon sink size as measured by flux towers compared to long-term direct measures of carbon stock change. This would improve our fundamental understanding of carbon balances (gains/losses) and residence times in these dynamic ecosystems. The long-term impacts of these land use changes on carbon storage are poorly understood, therefore this new knowledge is vital in determining the viability of 'carbon farming' in these landscapes. More accurate information would guide improved land management given the intensification of land use, weed invasion and fire regime change in northern Australia.Read moreRead less
What is 'natural'?: Locating and deciphering pre-human records of vegetation from northern Australian savannahs. The nature and magnitude of the environmental impact of human colonisation of Australia are fundamental issues in Australian prehistory and ecology. The project will locate and develop archives of environmental change from sinkholes in the Northern Territory that date back to the Last interglacial - a period which had a similar climate to the present day, but was before humans arrived ....What is 'natural'?: Locating and deciphering pre-human records of vegetation from northern Australian savannahs.
