They will understand how the traits of grassland species determine their response to management, and how this knowledge is applied in practice.
Learning objectiveStudents will be able to:
- Identify a plant's functional type, growth form and reproductive strategy and derive expectations regarding its response to management and its role in a plant community;
- Recognize grassland types from their structure and species composition, and explain how they depend on soil conditions, microclimate and management;
- Describe and explain changes in grassland composition after establishment and implications for grassland use;
- Survey plant species composition and vegetation structure with established methods; measure soil properties and microclimate;
- Carry out a field survey or a field experiment with a correct design; analyse the resulting data.
ContentWir führen Untersuchungen an der ETH Hönggerberg und in der Umgebung durch, um die Funktionsweise und Nutzung von Wiesen (Grünland) zu verstehen.
Wir beginnen mit Populationen einzelner Pflanzenarten. Wie wachsen, überleben und vermehren sich die Pflanzen? Wieviel investieren sie in verschiedene Möglichkeiten der Vermehrung? Wie flexibel sind sie, und welche Strategien sind wann günstig?
Wir vergleichen dann verschieden genutze Gründlandtypen miteinander: wie können wir sie schnell erkennen und ökologisch einordnen?
Für das Praktikum haben wir Feldeperimente mit unterschiedlichen Wiesenmischungen angelegt. Die Versuchsflächen werden unterschiedlich geschnitten und gedüngt. Wir untersuchen, welche Pflanzentypen durch welche Nutzung gefördert werden, wie sich die Bestände mit der Zeit ändern, und ob artenreiche Wiesen stabiler sind als artenarme. Dazu führen wir Vegetationsaufnahmen durch, analysieren Bodenproben und messen Temperatur und Strahlung. Die Daten werden ausgewertet und mit Postern präsentiert und diskutiert. Wir vergleichen die Ergebnisse mit den Nutzungsempfehlungen für die Praxis.
Schliesslich besuchen wir Feldexperimente, die von Praktikern angelegt und unterhalten werden. Die Projektleiter werden die Versuche vorstellen und über ihre Arbeit in der ökologischen Praxis berichten.
Lecture notesHandouts will be supplied in class.
LiteratureSpecialized literature will be available during classes
Prerequisites / NoticeBei den Felduntersuchungen sind gute Kleidung und Schuhe, Sonnen- und Regenschutz, sowie Massnahmen gegen Zeckenkrankheiten notwendig; die TeilnehmerInnen sind hierfür selbst verantwortlich.

701-0034-14LIntegrated Practical: Analysis of Urban Food Systems Information Restricted registration - show details W1.5 credits3PH. Moschitz
AbstractThe course deals with the analysis of Urban Food Systems (UFS). UFS include all processes that food runs through in a particular space (here: the city of Zurich): production, processing, distribution, consumption, waste disposal. We will analyse those processes with selected examples and particularly consider the role of the different actors of administration, market, and civil society.
Learning objective- Knowledge of the relevant actors and processes in the urban food system
- Critical reflection of framework conditions of the food system
- Factors influencing food in a city
- Understanding the relationships between administration/policy, civil society, and the market; that influence the food system
- Dealing with different sources and qualities of data (statistics, expert interviews)
- Testing possibilities of processing and presentation of data from different sources
ContentWie ernährt sich eine Stadt? Wie gelangen täglich ausreichend Lebensmittel in guter Qualität in Lebensmittelgeschäfte, und zu den Konsumentinnen und Konsumenten? Wo und wann werden Lebensmittel eingekauft? Welche Rolle spielt die Ausser-Haus-Verpflegung? Was passiert mit den Lebensmittelresten, dem Food Waste? Wo und wie werden die Nahrungsmittel produziert, wo verarbeitet und verpackt, für den Transport bereit gemacht? Welche Faktoren bestimmen, wie dieses komplexe Ernährungssystem funktioniert?

Mit diesen Fragen beschäftigt sich der Kurs, auch wenn in der Kürze nicht alle beantwortet werden können. Das Thema Essen und Ernährung wird für einmal nicht aus Sicht der Produktion, der Landwirtschaft, diskutiert, sondern aus Sicht des Konsums. Angesichts der Tatsache, dass 75% aller Einwohner der Schweiz in Städten leben, nehmen wir die Stadtregion als relevanten Raum des Konsums an. Aus dieser Perspektive wird im Kurs analysiert, wie Essen und Ernährung in einer Stadt (beispielhaft: Zürich) eingebettet ist in ein System verschiedener Akteure entlang der Wertschöpfungskette, von Produktion über Verarbeitung, Handel, Konsum und Entsorgung, aber auch in die unterschiedlichsten Bereiche unserer Gesellschaft und des Zusammenlebens: u.a. Soziales, Umwelt, Lebensqualität, Wirtschaft.

Die Studierenden setzen sich mit aktuellen Konzepten, wie food strategies, urban-rural relationships, alternative food networks, food sovereignty auseinander, diskutieren sie und wenden die Konzepte auf das Food System der Stadt Zürich an. Ein Bezug zum 'Milan Urban Food Policy Pact', den die Stadt Zürich unterzeichnet hat, wird hergestellt. Erkenntnisse aus folgenden aktuellen Europäischen und Nationalen Forschungsprojekten fliessen in das Praktikum ein: SUPURBFOOD (supurbfood.eu), FOODLINKS (foodlinkscommunity.net), Ernährungssystem Basel, Regionaler Konsum Freiburg.

Nach einem theoretischen Einstieg lernen die Studierenden in einer Exkursion (geplant: ein Lebensmittel-Verteilzentrum oder Gemüse-Waschanlage) einen Teil des Food Systems von Zürich kennen. Vor diesem Hintergrund wählen sie dann in Gruppen von 2-3 eine Fragestellung aus, die den Einfluss verschiedener Akteursgruppen (Verwaltung, Markt, Zivilgesellschaft) und ihre Beziehungen in der Wertschöpfungskette beispielhaft untersucht (wobei dies nicht abschliessend möglich sein wird). Die konkrete Fragestellung wird in Absprache mit den Akteuren in der Stadt bis zum Kurs entwickelt, um einen Bezug zu aktuellen Themen sicherzustellen.

Die Daten dazu sollen von den Studierenden eigenständig recherchiert werden; Datenquellen sind hierbei Statistiken, Websites und Jahresberichte von Unternehmen, Expertenbefragungen, sowie ggf. Kurzumfragen bei Konsumenten.

Am Ende wird jede Gruppe ihre Ergebnisse in einem Factsheet zusammenfassen und sie darüber hinaus kreativ aufbereiten: anhand einer Kurzgeschichte (story telling), eines Comics, einer Collage, o.ä. Diese werden den anderen Teilnehmerinnen und Teilnehmern im IP vorgestellt.

701-0034-18LIntegrated Practical: Nutrient Flows in Agroecosystems Restricted registration - show details W1.5 credits3PE. K. Bünemann König
AbstractNutrient flows (from the global scale to the farm level) play an important role in the area of conflict between agricultural production and environmental protection. The students get to know nutrient balances, establish a "SuisseBilanz", and compute conversion scenarios (e.g. to a stockless farm). Finally, we will discuss possibilities to close nutrient cycles and minimize nutrient losses.
Learning objectiveThe students can:
- explain N and P flows on a farm, national and global level
- critically judge the Swiss fertilization planning with respect to potential nutrient losses
- distinguish different types of nutrient balances
- use the "SuisseBilanz" to analyse a farm, and as a planning tool
- compare options to close nutrient cycles
- discuss consequences of animal production on nutrient flows and environmental impact.
ContentIm Spannungsfeld zwischen landwirtschaftlicher Produktion, Nachhaltigkeit und Einfluss auf natürliche Ökosysteme spielen Nährstoffflüsse auf verschiedenen Skalenebenen eine wichtige Rolle. Dabei können Nährstoffbilanzen einerseits für ein besseres Verständnis von Nährstoffkreisläufen und -effizienz und andererseits als Regulierungsinstrument für ein umweltschonendes Nährstoffmanagement genutzt werden. In diesem Praktikum lernen die Studierenden verschiedene Typen von Nährstoffbilanzen kennen. Unter Benutzung der Düngungsempfehlungen der Schweiz erarbeiten die Studierenden eine Suisse-Bilanz für einen Beispielsbetrieb und rechnen verschiedene Umstellungsszenarien (z.B. auf einen viehlosen oder auf einen biologisch wirtschaftenden Betrieb). Im letzten Teil des Praktikums werden Möglichkeiten thematisiert, Nährstoffkreisläufe auf Betriebs- und Gesellschaftsebene zu schliessen und Nährstoffverluste zu minimieren.
Prerequisites / NoticeDas Praktikum beinhaltet eine Exkursion zu einem N-Düngungsversuch in Eschikon, eine Besichtigung eines landwirtschaftlichen Betriebes, und eine Exkursion zum Thema Nährstoffrecycling.
Die Studierenden benötigen einen Laptop für die verschiedenen Übungen und Rechenaufgaben.
