Increasingly extreme heat waves, droughts and floods contribute major uncertainties in predicting natural land-based climate change mitigation. This project will quantify current and future greenhouse gas absorption in a managed grassland ecosystem, and the new knowledge will contribute to carbon emissions offsets in climate change accounting schemes. We will conduct this research using a manipulative field experiment, controlled laboratory incubations, microbial gene analysis and mechanistic modelling to provide new insights into future potential climate change mitigation by soils.

日益极端的热浪、干旱和洪水给预测自然陆地气候变化减缓带来了重大不确定性。该项目将量化管理草地生态系统当前和未来的温室气体吸收量，新知识将有助于气候变化核算方案中的碳排放抵消。我们将利用操作性现场实验、受控实验室孵化、微生物基因分析和机械建模来进行这项研究，为未来土壤减缓气候变化的潜力提供新的见解。
