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

该项目旨在提高我们对自然和改造稀树草原中碳循环的理解。它试图解决一个大的差异，在热带稀树草原碳汇的大小相比，长期直接措施的碳储量变化的通量塔测量。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。这些土地利用变化对碳储存的长期影响知之甚少，因此，这一新知识对于确定这些景观中“碳农业”的可行性至关重要。鉴于澳大利亚北方土地利用的加剧、杂草入侵和火灾状况的变化，更准确的信息将指导改进土地管理。

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.
