| Description | Welcome to our webinar on "Balancing Soil Carbon Gains and Nitrous Oxide Emissions: Evaluating the Net Impact of Natural Climate Solutions in Croplands" Soil-based natural climate solutions (NCS) can contribute to net carbon dioxide removal in croplands. However, concerns exist that increasing soil organic carbon through NCS might also elevate soil nitrous oxide emissions, potentially offsetting the benefits of carbon sequestration. This underscores the importance of adopting a net GHG approach when assessing the impact of these interventions. Dr Shelby McClelland and Dr Mark Farrell will discuss findings from field experiments and simulations to determine whether management practices like reduced tillage and cover crops could lead to increased nitrous oxide emissions, potentially negating the global benefits of soil organic carbon. Additionally, it will explore management solutions based on scientific understanding to enhance productivity while minimizing the impact on soil and the environment. | |

| Speakers | | Shelby C. McClelland, New York University Shelby C. McClelland (Ph.D. Colorado State University) is an ecosystem ecologist and soil biogeochemist with broad research interests in climate change and food systems in the Department of Environmental Studies at New York University. Her most recent work is at the intersection of global change and agriculture, specifically climate change mitigation in crop and livestock systems. Shelby is particularly interested in trade-offs, like yield, land-use, and biodiversity, associated with various mitigation pathways towards limiting global temperatures well-below 2°C. As part of her work through the Center for Environmental and Animal Protection (CEAP), she is also quantifying the impacts of GHG mitigation pathways on farmed animals. Shelby was previously a Postdoctoral Researcher at Cornell University, a consultant at the United Nations Food and Agriculture Organization, and a researcher at Environmental Defense Fund. She was also an Adjunct Professor in the Department of Environmental Studies.

 | Mark Farrell, CSIRO Australia Dr Mark Farrell leads research into carbon and nitrogen cycling in soils and the wider environment at CSIRO Australia. Mark's current research includes national projects to quantify soil carbon stocks and its drivers of change, improved process understanding of soil nitrogen dynamics and integration of this new knowledge into agricultural system models. He has a particular research interest in the interplay between C and N, and the implications of these interactions for management of soils. Having over 15 years of experience in a range of agricultural and natural systems, Mark's work seeks to find management solutions underpinned by sound mechanistic understanding to improve productivity whilst limiting and reducing impact on the soil and wider environment.
