Tropical savanna burning represents an important but poorly understood component of the global carbon cycle. This project will quantify the dynamics of pyrogenic carbon (charcoal, soot, biochar) production and dispersal during savanna fires. Pyrogenic carbon is important because it can persist in the environment for thousands of years. Hence it represents both a 'sink' for carbon and a source of information about past environments. The project will also assist in validating 'biochar' as a new tool for carbon sequestration, an enable a deeper understanding of the interactions between fire, humans, vegetation and climate.

热带稀树草原燃烧是全球碳循环中一个重要但鲜为人知的组成部分。该项目将量化热带草原火灾期间热原碳（木炭、煤烟、生物炭）产生和扩散的动态。热原碳很重要，因为它可以在环境中存在数千年。因此，它既是碳的“汇”，也是过去环境信息的来源。该项目还将协助验证“生物炭”作为碳封存的新工具，从而加深对火灾、人类、植被和气候之间相互作用的理解。
