| Kurzbeschreibung | In diesem Kurs wird der Einfluss von Umweltfaktoren (z. B. Licht, Temperatur, Feuchte, CO2-Konzentrationen, etc.) auf die Physiologie der Pflanzen behandelt: Wasseraufnahme und -Transport, Transpiration, CO2-Gaswechsel von Pflanzen (Photosynthese, Atmung), Wachstum und C-Allokation, Ertrag und Produktion, Stressphysiologie. Praktische Übungen im Labor und im Freiland runden dieses Programm ab. | |||||||||||||||||||||||||||||
| Lernziel | Die Studierenden werden verstehen, wie pflanzenphysiologische Prozesse auf Umweltfaktoren reagieren. Sie lernen damit die theoretischen Grundlagen und Fachbegriffe der Ökophysiologie kennen, die zur Analyse von Ertragspotentialen einsetzen werden. Klassische und aktuelle ökophysiologische Forschung wird vorgestellt, und moderne Analysegeräte zur Bestimmung ökophysiologischer Parameter benutzt. | |||||||||||||||||||||||||||||
| Inhalt | Das Ziel vieler landwirtschaftlicher Managemententscheidungen, d. h., das Erhöhen der Produktivität und des Ertrages, basiert häufig auf Reaktionen der Pflanzen auf Umweltfaktoren, z. B. Nährstoff- und Wasserangebot, Licht, etc. Daher werden in diesem Kurs der Einfluss von Umweltfaktoren auf die pflanzliche Physiologie behandelt, z. B. auf den Gaswechsel von Pflanzen (Photosynthese, Atmung, Transpiration), auf die Nährstoff- und Wasseraufnahme und den -Transport in Pflanzen, auf das Wachstum, den Ertrag und die C-Allokation, auf die Produktion und Qualität der produzierten Biomasse. Anhand der wichtigsten Pflanzenarten in Schweizer Graslandökosystemen werden diese theoretischen Kenntnisse vertieft und Aspekte der Bewirtschaftung (Schnitt, Düngung, etc.) angesprochen. | |||||||||||||||||||||||||||||

| 751-4003-01L | Current Topics in Grassland Sciences (HS) | W | 2 KP | 2S | A. K. Gilgen | |||||||||||||||||||||||||
| Kurzbeschreibung | Research results in agro- and forest ecosystem sciences will be presented by experienced researchers as well as Ph.D. and graduate students. Citation classics as well as recent research results will be discussed. Topics will range from plant ecophysiology, biodiversity and biogeochemistry to management aspects in agro- and forest ecosystems. | |||||||||||||||||||||||||||||
| Lernziel | Students will be able to understand and evaluate experimental design and data interpretation of on-going studies, be able to critically analyze published research results, practice to present and discuss results in the public, and gain a broad knowledge of recent research and current topics in agro- and forest ecosystem sciences. | |||||||||||||||||||||||||||||

| 751-4104-00L | Alternative Crops | W | 2 KP | 2V | A. Walter, K. Berger Büter | |||||||||||||||||||||||||
| Kurzbeschreibung | Few crops dominate the crop rotations worldwide. Following the goal of an increased agricultural biodiversity, species such as buckwheat but also medicinal plants might become more important in future. The biology, physiology, stress tolerance and central aspects of the value-added chain of the above-mentioned and of other alternative crops will be depicted. | |||||||||||||||||||||||||||||
| Lernziel | Im Verlauf des Kurses lernen die Studierenden, das Potential verschiedenster Kulturpflanzenarten im Vergleich zu den Hauptkulturarten auf der Basis ihrer biologischen und agronomischen Eigenschaften zu beurteilen. Jeder Studierende nimmt die Beurteilung einer von ihm oder ihr selbst ausgewählten alternativen Kulturart vor und stellt diese den anderen Kursteilnehmern dar. Dabei werden Fachartikel sowie Einträge in Wikipedia zu Hilfe gezogen und selbst bearbeitet. | |||||||||||||||||||||||||||||

| Kurzbeschreibung | Im Rahmen eines modernen Unkrautbekämpfungs-Systems werden Kenntnisse zur Unkrautbiologie, -ökologie, die Populationsdynamik, zu Saaten-Unkraut Interaktionen und zu unterschiedlichen Unkrautbekämpfungsmassnamen vermittelt. Unkraut wird als Teil eines Habitats verstanden und nicht bloss als unerwünschte Pflanzen innerhalb einer Saat. | |||||||||||||||||||||||||||||
| Lernziel | At the end of the course the students are qualified to develop sustainable solutions for weed problems in agricultural and natural habitats. | |||||||||||||||||||||||||||||
| Inhalt | Modern weed management comprises competent knowledge of weed biology, weed ecology, population dynamics, crop-weed-interactions and different measures to control weeds. Weeds are understood to be rather part of a habitat or a cropping system than just unwanted plants in crops. Accordingly, this knowledge will be imparted during the course and will be required to understand the mechanisms of integrated weed control strategies. | |||||||||||||||||||||||||||||

| Lernziel | (1) Systematically analyse and discuss case studies from ongoing agroecological and food system research. (2) Learn and experiment on methods for field and laboratory investigations in agroecology. (3) Engage with positive and empowering frameworks that motivate critical reflection and action on the types of transformative responses needed to adapt and thrive within agricultural and food systems. (4) Reflect critically on agricultural and food system transformation tools and methods from the perspective a food system stakeholder. (5) Identify and describe institutions in the context of sustainable agricultural development (for Bachelor and Master thesis and internships). | |||||||||||||||||||||||||||||
| Inhalt | The course will address a wide range of agricultural and food system challenges (e.g. food security, climate change, soil degradation, etc.) in both temperate and tropical contexts, from building food system resilience through innovative measures, to addressing soil fertility and GHG emissions. A wide variety of case studies will be presented, covering different scales (e.g. value-chains, farm and soil management). The class is complemented by a role-playing exercise on food system transformation. Students will gain an overview on institutions and actors’ roles in the field of sustainable agricultural development. Throughout the exercise, students will learn to cooperate through a teamwork exercise and understand what is the role of each stakeholders in the food system in order to support a sustainable transformation. | |||||||||||||||||||||||||||||
