Greenhouse gases threaten the global climate. Many estimates of vegetation as sinks and sources for greenhouse gases have a high degree of uncertainty. This project will generate important information about greenhouse gas emissions from Queensland coastal vegetation. Characterised by moist and nutrient rich conditions, sugarcane fields and mangrove ecosystems represent significant sources/sinks of potent greenhouse gases nitrous oxide and methane. Sugarcane and mangroves exposed to different nutrient inputs will allow to (i) identify mechanisms of N2O and CH4 emission, (ii) model N2O and CH4 emissions under different nutrient and climate conditions, and (iii) control/reduce emissions by improving coastal ecosystem management.

温室气体威胁着全球气候。许多关于植被作为温室气体汇和源的估计具有高度的不确定性。该项目将产生有关昆士兰州沿海植被温室气体排放的重要信息。甘蔗田和红树林生态系统的特点是潮湿和营养丰富，是强温室气体一氧化二氮和甲烷的重要来源/汇。甘蔗和红树林暴露于不同的养分输入将允许（i）确定N2 O和CH 4排放的机制，（ii）在不同的养分和气候条件下模拟N2 O和CH 4排放，以及（iii）通过改善沿海生态系统管理来控制/减少排放。
