The integrated assessment of global and regional reactive Nitrogen mitigation potential

The safe planetary boundary for the Nitrogen (N) cycle has been considerably exceeded by excessive reactive Nitrogen (Nr) emissions, leading to significant environmental and health issues. Reducing N pollution has become an important goal on the international policy agenda. By developing and applying a multi-model (CHANS, GAINS, GEO-Chem) framework that integrates N cycling, cost-benefit analysis, and scenario analysis, key questions are explored on the cost-effective mitigation pathways and strategies of achieving ambitious Nr mitigation targets and their co-benefits on improvements in air pollution, human health, ecosystem service and resource efficiency.

Xiuming is currently a PhD candidate supervised by Prof Deli Chen at the University of Melbourne. She is skilled in data analysis and visualization with different statistical software, ArcGIS, uncertainty analysis, and meta-analysis. Xiuming received a Master of Science in Ecology from Zhejiang University. During her master’s, her research focused on identifying the role and contribution of NH3 emissions in the formation of PM2.5 and compiling the high-resolution NH3 emission inventory in China with CHANS model, satellite observation, and N deposition monitoring. She is now dealing with the health impact, costs, and benefits of collaborative N and GHG reduction scenarios globally. Xiuming works closely with scientists in Australia, China, the US and Europe and maintains an active research agenda in several international and interdisciplinary science projects. She has authored and co-authored more than 15 publications in top scientific journals, including Nature, Science, Nature communications, Nature food, and EST.
