Integrative Assessment of Disturbance and Land-Use Change on the Total Greenhouse Gas Balance and Nutrient Cycling in Savanna Ecosystems

Grant number: LP0774812 | Funding period: 2007 - 2009

Abstract

Climate change and variability is expected to have an impact on the NT environment and economy. This project will enable NT specific calibrations of climate variability-land use models, such as the National Carbon Accounting System. The NT Government will have access to a high quality database and calibrated models relating to greenhouse gas emissions as a function of land use change. The project will improve estimates and management of GHG and provide a basis for the NT to potentially exploit future carbon-trading initiatives or GHG abatement schemes as fundamental data describing emissions as a function of land use will be available. This is of national significance given the size of the s..
