Organizers invite abstracts for the 2024 European Geosciences Union (EGU) General Assembly. This hybrid conference will convene 14-19 April 2024 in Vienna, Austria and online.
Conveners of the following sessions invite abstracts:
SESSION BG1.6: Nitrogen Cycling in the Anthropocene: Microbiological Processes, Land-atmosphere- Interactions, and Global Change Feedbacks
Convener: Sami Ullah, Li Li, Dianming Wu, Peter Dörsch, and Tuula Larmola
Session Abstract:
Anthropogenic disturbance of the global nitrogen (N) cycle has more than doubled the amount of reactive N circulating in the terrestrial biosphere alone. Exchange of reactive/non-reactive nitrogen gases between land and atmosphere are strongly affecting Earth’s atmospheric composition, air quality, global warming, climate change, and human health. This session seeks to improve our understanding of a) how intensification of reactive N use, land management, and climate change affects the pools and fluxes of nitrogen in terrestrial and aquatic ecosystems; b) and how reactive N enrichment of land and water will affect the future carbon sink of natural ecosystems as well as atmospheric exchanges of reactive (NO, N2O, NH3, HONO, NO2, and non-reactive N (N2) gases with implications for global warming, climate change, and air quality. Conveners welcome contributions covering a wide range of experimental and modelling studies, which covers microbes-mediated and physico-chemical transformations and transport of nitrogen across the land-water-air continuum in natural ecosystems from local to regional and global scales. Furthermore, the interactions of nitrogen with other elemental cycles (e.g. phosphorus, carbon) and the impacts of these interactive feedbacks for soil health, biodiversity, and water and air quality will be explored in this session. Latest developments in methodological innovations and observational and experimental approaches for unravelling the complexities of nitrogen transformations and transport will also be of interest.

SSS9.11: The Role of Forest Management and Soils in Meeting Climate Change Mitigation Goals
Conveners: Tuula Larmola, Eduardo Martínez-García, Bertrand Guenet, and Marjo Palviainen
Session Abstract:
Forests play a pivotal role in the global carbon cycle by storing about half of the world's organic carbon. In most climatic regions, the organic carbon stocks in soil exceed those in plant biomass. In this context, forest management contributes to climate change mitigation by affecting soil processes and functioning, and consequently, carbon sequestration.
Comprehensive understanding how forest management affects soil processes is urgently needed. Significant knowledge gaps still remain concerning the effect of forest management on soil carbon balances and greenhouse gas exchanges. Furthermore, the effectiveness of climate-smart forestry practices relies on both management characteristics such as the level of management intensity and the recovery time after management as well as site-specific conditions as for example the soil type, soil physical, chemical, and biological characteristics and conditions, topography, vegetation composition, and climatic factors. In addition, there is a lack of consistency in the way that different forest management practices can prevent the soil carbon loss after natural disturbances. Finally, the effects of forest management on soil are not yet comprehensively integrated into modelling tools for decision-making, which could potentially lead to neglecting these effects when formulating policies to achieve carbon neutrality objectives.
This session invites experimental and modelling contributions from forests around the world on exploring the current understanding of the effects of forest management on soil carbon sequestration and other processes to develop effective forest-based climate change mitigation strategies.
Specific topics include, but are not limited to:
- Advance knowledge concerning the effects of forest management on soil carbon sequestration, greenhouse gas balances, biodiversity, nutrient stocks, organic matter quality, water resources, and stabilization processes;
- Enhancing comprehension of the impacts of natural disturbances and preventing forest management on soil functioning and resilience; and
- Improve understanding of modelling on the potential of forest management to mitigate climate change.
