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.

越来越极端的热浪、干旱和洪水在预测自然陆地气候变化减缓方面造成了很大的不确定性。该项目将量化管理草原生态系统当前和未来的温室气体吸收，新知识将有助于气候变化核算方案中的碳排放抵消。我们将使用操纵性田间实验，受控实验室孵育，微生物基因分析和机械建模进行这项研究，以提供对未来潜在的土壤减缓气候变化的新见解。
