751-5000-00L | Sustainable Agroecosystems I | 2 KP | 2G | J. Six, K. Benabderrazik, M. Hartmann | |
Kurzbeschreibung | Welche Faktoren, Prozesse und Interaktionen beeinflussen die Funktionsfähigkeit von Agrarökosystemen? In dieser Lehrveranstaltung mit integrierter Übung und Exkursion werden landwirtschaftliche Verfahren im Hinblick auf eine Förderung der Ressourceneffizienz analysiert, wobei die Verringerung negativer Umweltwirkungen und die Sicherung der sozio-ökonomischen Tragfähigkeit berücksichtigt wird. | ||||
Lernziel | Studierende setzen sich kritisch mit den Konzepten der nachhaltigen Landwirtschaft auseinander. | ||||
Inhalt | The course will address a wide range of agricultural and food systems topics in both temperate and tropical contexts, from the diversity of farming system, to climate smart agriculture to sustainable assessment. A wide variety of case studies will be presented, and complemented with a farm visit during the semester. Along the semester, the class is integrating practical exercises within a greenhouse. | ||||

Voraussetzungen / Besonderes | Die integrierten Übungen ermöglichen es den Studierenden das erworbene Wissen in einem mehrmonatigen Gewächshausexperiment zu erproben. | ||||
751-5102-00L | Biogeochemical Modeling of Agroecosystems | 3 KP | 2G | M. Van de Broek, J. Six | |
Kurzbeschreibung | This class provides an introduction to biogeochemical modeling in the context of agricultural systems. It covers the general background and principles of modeling agricultural biogeochemistry in a theoretical part (e.g., plant growth, soil C and N dynamics and soil greenhouse gas emissions), while the focus is on learning how to code biogeochemical models in the R software environment. | ||||
Lernziel | The aim of the course is to (i) introduce students to a range of concepts applied in biogeochemical modelling of agroecosystems, with an emphasis on soil biogeochemistry (carbon and nitrogen cycling) and (ii) teach students the basics of coding biogeochemical models in a free and open-source software environment (R). The focus of the course will be on hands-on coding. At the end of the course, students will: - Be able to critically evaluate different concepts applied in widely used biogeochemical models in an agricultural context - Be Familiar with the basic concepts of programming that are specifically applicable to modelling biogeochemical cycles (carbon and nitrogen) in an agricultural context - Be able to come up with basic conceptual models to evaluate how carbon and nitrogen cycle in agricultural soils, given certain constraints and - Be able to write computer codes to convert their conceptual models to numerical models and evaluate model outcomes. | ||||
Inhalt | The class consists of (i) a limited theoretical part, in which students learn the basics of biogeochemical models in an agricultural context and (ii) a more extensive part, in which students learn to program simple biogeochemical models in the R software environment. | ||||
Literatur | The following handbooks serve as the basis for the concepts and skills the students will learn in the course: - Soetaert and Herman, 2009, A Practical Guide to Ecological Modelling, Springer Netherlands. - Wallach et al., 2018, Working with Dynamic Crop Models, 3rd Edition, Academic Press. | ||||
Voraussetzungen / Besonderes | Students signing up for this course should have a strong interest in modeling of agroecosystem processes. Prior knowledge of the R programming language (or similar) is a plus but is not required, as all basic programming concepts will be explained. |
