Description

The potential carbon storage in soil organic matter depends on both biophysical properties of an ecosystem as well as the challenges arising from implementation. My presentation will address how the management of disturbances such as fire, grazing, and agriculture change net-greenhouse gas emissions. First, using a large experimental network, I present evidence for the scope of fire management in determining soil carbon storage across ecosystems. Second, I illustrate how managed grazing in rangelands can sequester soil carbon, but the net-emissions from implementation are contingent on changes in plant productivity, emissions from feed production and global trade. Finally, I will discuss how soil CO2 removal in croplands create trade-offs with other on-farm emission pathways. In summary, while some climate solutions are promising, soils deserve a critical re-evaluation through a lens that contextualizes ecosystems within the complexities of how humans both disturb and manage systems.

Bio

I received my PhD in 2016 from Princeton University in Ecology and went on to do a postdoctoral fellowship at Stanford University as a NOAA Climate and Global Change fellow and a USDA National Institute of Food and Agriculture fellow. I moved to Cambridge to take up an Assistant Professor position in 2020 where I have developed a research program centered around answering key global change questions. Specifically, my research leverages basic science to create a forward-looking research program that works with industry and government to identify the research advances needed for successful implementation of sustainability solutions. My research blends basic science in ecology and carbon cycling with applied science that evaluates how global change will affect ecosystem functioning, and solution-oriented science developing ways to implement solutions in policy and business settings to help abate climate change.
