| Inhalt | The functioning of soils in the global carbon cycle and effects induced by changes in climate, land-use, and land management are introduced. Priority will be given to global pools and fluxes of soil carbon and how they are altered as well as to biological, chemical, physical and anthropogenic factors which drive input and turnover rates and stabilization of organic matter in soils. Selected analytical methods to assess pools, fluxes, and composition of soil organic matter will be presented as well as an introduction to basic conceptual models that are used to describe soil C-dynamics. Finally, the question of the most important human-induced environmental changes in organic matter cycling in soil (e.g., fertilization, fire, drainage, tillage) and major unknowns of soil C storage will be discussed, also in view of the 4 permil initiative, the Paris agreement, and the potential of soils to sequester more carbon. |
| Lernziele | You comprehend major drivers and processes related to soil as a carbon reservoir and understand basic experimental and analytical tools used to describe carbon cycling and structure in soil. You are qualified to analyse scientific reports and put them into context, present them in a nutshell, and discuss them critically. You are able to assess the role of soils as carbon sinks as part of a global GHG mitigation effort. |

Modul: Environmental Geosciences and Biogeochemistry (Masterstudium: Geowissenschaften) Modul: Fields: Environment and Development (Master Studiengang: African Studies) |
| Leistungsüberprüfung | Lehrveranst.-begleitend |
| Hinweise zur Leistungsüberprüfung | At selected dates of the class students present and discuss research topics based on published scientific papers, preferably supported by a PowerPoint presentation. The report must be summarized and distributed as a handout. To gain credit points requires (1) regular presence at the sessions (attendance list!), (2) active participation during the discussion and (3) pass of the oral presentation and the handout. Details are given in the first session. The seminar is designed for students in Environmental (Geo)sciences at MSc level. |
