First Presentation: Samantha Quinn, University of Edinburgh, Institute for Energy Systems
PIGS – what does it stand for?
The ever-expanding Policy and Innovation Group within IES looks at the relationship between policy, economics and innovation, and how we put those together to make a working strategy. In this talk, you’ll find out more about who we are and the variety of projects we’re currently working on.
Samantha is an RA within the PIGs group in IES. She holds a BSc in Business Administration and Marketing from Regis University in Denver, Colorado and an MSc in Ecologic Economics from the University of Edinburgh. She is currently focused on co-coordinating the DTOcean Project and writing roadmaps and proposals. Prior to moving to Edinburgh, she worked at the US Department of Energy’s Wind and Water Power Program as a project manager.
Second Presentation: Dr YUE Yao, Wuhan University, China
Erosion-induced CO2 flux of China
Soil erosion by water impacts soil organic carbon (SOC) stocks and alters CO2 fluxes exchanged with the atmosphere at landscape and regional scale. The role of erosion as a net sink or source of atmospheric CO2 remains highly debated, and little information is available at scales larger than points for a few small catchments. This study is a first attempt to quantify the lateral transport of soil carbon and consequent land-atmosphere CO2 fluxes at the scale of China where severe erosion has been experienced for several decades. Based on the distribution of soil erosion rates derived from detailed national surveys and soil carbon inventories, here we show that water erosion in China displaced 180 ± 80 Mt C yr-1 of SOC during the last 20 years. Consequently, the net land-atmosphere CO2 flux is estimated to be a net CO2 sink of 45 ± 25 Mt C yr-1, which is equivalent to 8–37 % of the terrestrial carbon sink previously assessed in China.
Dr YUE Yao is a lecturer from School of Water Resources and Hydropower Engineering, Wuhan University, China, and now working with Prof. Alistair Borthwick as an Academic Visitor. She received her PhD in the Department of Environmental Engineering, Peking University, China. I am now involved in the project of “All Material River Fluxes of China” co-organized by Chinese Academy of Sciences and the Ministry of Water Resources, P.R. China.
