Up in smoke and out to sea? Carbon, water and land use change in savanna

这个项目旨在提高我们对自然和改造的热带稀树草原的碳循环的理解。它试图解决通量塔测量的稀树草原碳汇大小与碳储量变化的长期直接测量的巨大差异。这将提高我们对这些动态生态系统中碳平衡（收益/损失）和停留时间的基本理解。人们对这些土地利用变化对碳储存的长期影响知之甚少，因此这些新知识对于确定这些景观中“碳农业”的可行性至关重要。考虑到澳大利亚北部土地利用的集约化、杂草入侵和火灾制度的变化，更准确的信息将指导改善土地管理。

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.
