Peatlands represent a globally significant stock of soil carbon and exchange greenhouse gases (GHGs) with the atmosphere, including methane. Destabilization of peatland carbon stocks, in response to warming or other human-induced disturbance, contributes to climate change. The research program will improve our understanding of the interactions between peatlands and climate by: 1) evaluating the effect of climate change on peatland GHG fluxes, 2) determining how industrial disturbance affects plant-soil interactions linked to carbon cycling, and 3) developing improved GHG emission factors for managed peatlands. Results will inform improved peatland management, enabling the use of peatlands as natural climate solutions.

泥炭地代表着全球重要的土壤碳储量，并与大气交换温室气体（ghg），包括甲烷。由于气候变暖或其他人为干扰，泥炭地碳储量的不稳定加剧了气候变化。该研究项目将通过评估气候变化对泥炭地温室气体通量的影响，确定工业干扰如何影响与碳循环相关的植物-土壤相互作用，以及开发改进的管理泥炭地温室气体排放因子，提高我们对泥炭地与气候之间相互作用的理解。研究结果将为改善泥炭地管理提供信息，使泥炭地成为自然气候解决方案。
