363-0588-00LComplex Networks Information W4 KP2V + 1UF. Schweitzer, I. Scholtes
KurzbeschreibungThe course provides an overview of the methods and abstractions used in (i) the quantitative study of complex networks, (ii) empirical network analysis, (iii) the study of dynamical processes in networked systems, (iv) the analysis of systemic risk in networked systems, (v) the study of network evolution, and (vi) data mining techniques for networked data sets.
Lernziel* the network approach to complex systems, where actors are represented as nodes and interactions are represented as links
* learn about structural properties of classes of networks
* learn about feedback mechanism in the formation of networks
* understand systemic risk as emergent property in networked systems
* learn about statistical inference techniques for data on networked systems
* learn methods and abstractions used in the growing literature on complex networks
InhaltNetworks matter! This holds for social and economic systems, for technical infrastructures as well as for information systems. Increasingly, these networked systems are outside the control of a centralized authority but rather evolve in a distributed and self-organized way. How can we understand their evolution and what are the local processes that shape their global features? How does their topology influence dynamical processes like diffusion? And how can we characterize the importance and/or role of specific nodes? This course provides a systematic answer to such questions, by developing methods and tools which can be applied to networks in diverse areas like infrastructure, communication, information systems or (online) social networks. In a network approach, agents in such systems (like e.g. humans, computers, documents, power plants, biological or financial entities) are represented as nodes, whereas their interactions are represented as links.

The first part of the course, "Introduction to networks: basic and advanced metrics", describes how networks can be represented mathematically and how the properties of their link structures can be quantified empirically.

In a second part "Stochastic Models of Complex Networks" we address how analytical statements about crucial properties like connectedness or robustness can be made based on simple macroscopic stochastic models without knowing the details of a topology.

In the third part we address "Dynamical processes on complex networks". We show how a simple model for a random walk in networks can give insights into the authority of nodes, the efficiency of diffusion processes as well as the existence of community structures.

A fourth part "Statistical Physics of Networks: Optimisation and Inference" introduces models for the emergence of complex topological features which are due to stochastic optimization processes, as well as algorithmic approaches to automatically infer knowledge about structures and patterns from network data sets.

In a fifth part, we address "Network Dynamics", introducing models for the emergence of complex features that are due to (i) feedback phenomena in simple network growth processes or (iii) order correlations in systems with highly dynamic links.

A final part studies "Multiple roles of nodes and links", introducing recent research on automated role discovery in networks, as well as models for networks with multiple layers.

Maximale Teilnehmerzahl: 20
W2 KP2GM. Sonnevelt, D. Barjolle
KurzbeschreibungBased on the complex nature and interactions of various driving forces such as e.g. poverty, resource scarcity, globalization and climate change, global food security depends on manifold aspects. To study food security, one must understand aspects such as the availability of, the access to and the adequate use of food as well as the stability of the economic, ecologic and political system.
LernzielThis year, the course focus on the role of Agroecology as a concept to support food security. Agroecology, once the exclusive domain of food sovereignty and ecology movements, it has begun to be promoted enthusiastically in both developed and developing countries by non-government organizations, international development organizations and others seeking more sustainable food production and consumption systems. The course will elaborate potential and bottlenecks of the concept for global food security.

A more detailed program will be uploaded in early 2015.
InhaltThe main block of the course is a three-days workshop/seminar at the FAO headquarter in Rome during the week of 06.04.-10.04.2015 (exact dates will be announced in early 2015).
In February and March 2015, two preparatory events (each lasting +/- two hours) will be held at ETH Zurich. Exact date and time will be announced in early 2015.
SkriptBooks and Articles.

We will compose a document of the material presented and elaborated during the workshop for distribution after the event.
Voraussetzungen / BesonderesThe Lecture is held in English and is limited to 20 MSc-students preferably from agriculture, environment and food sciences.
751-2102-00LHistory of Food and AgricultureW3 KP2VP. Aerni
KurzbeschreibungKnowledge about the history of food and agriculture is crucial to understanding the emergence of modern agriculture and public resistance to industrial farming. The lecture discusses the evolution of agriculture and its impact on social structures, human health and the environment from an anthropological, a cultural, a political and a technological point of view.
Lernziel- to become familiar with the milestones of the history of food and agriculture
- to understand innovation in agriculture as one of the major forces of change in the history of mankind
- to learn how perceptions, politics and policies in food and agriculture are shaped by social, technological and environmental change
- to be able to embed the current debate on the food crisis and climate change into a historical context
InhaltThis lecture starts with the Neolithic revolution and its cultural and environmental impact on humankind. In this context, it will discuss the transition from hunter-and-gatherer societies to societies that rely more upon the domestication of nature (agriculture and pastoralism) (Keeley 1996, Diamond 1999).
The various forms of domestication of plants and animals and their economic, political and environmental implications for society will be discussed using examples from different parts of the world (Stone et al.2007).
The emergence of civilization based on agrarian law will be discussed by using the example of the Roman Republic and later the Roman Empire (Weber 1891, Love, 1996).
Subsequent innovations such as the three-field system in medieval times, the introduction of new plants and animals during the colonial period, and scientific and technological breakthroughs in plant breeding, agricultural practices and food preservation in the 19th century gave a major boost to agricultural productivity, food availability and agro-biodiversity. These prior developments also laid the foundation for industrial agriculture at the beginning of the 20th century (Kingsbury 2009). The global implications resulting from change in food preferences and agricultural innovation will be illustrated by using selected examples of innovations in food and agriculture (Braudel 2002, Pendergast 2010).
Public resistance to industrial agriculture manifested itself in the early 1920s with counter-movements such as biodynamic farming (Kingsbury 2009) but also with organized lobbying groups that fought against change caused by refrigeration and cheap food (Freidberg 2009). Applying science to plant and animal breeding also caused a cultural divide in biology departments at universities between those who changed nature (plant breeders) and those who wanted to preserve it (botanists, ecologists) (Anker 2001).
The period during and after the two World Wars changed the business of agriculture entirely. Food security became a matter of national security and thus justified state intervention on all levels in the production of food from farm to fork. This also helps explain why the Green Revolution was largely a public sector initiative that cared more for productivity increases on the supply side than for consumer preferences on the demand side (Aerni 2007). After the end of the Cold War, attention shifted from the supply side to the demand side and thus from food security to food safety.
Food safety concerns were largely due to distrust of industrial agriculture and this led to major policy shifts in the way agricultural subsidies and resources were allocated and how food safety was managed and monitored. While the public sector largely withdrew from investing in productivity-related agricultural research, the private sector started to invest more. This led to the growing need to engage again in public-private partnership, as had been the case in the 19th century. Despite the Agreement on Agriculture of the World Trade Organization, agricultural trade remains highly restricted and the growing vertical integration of the food supply chain tends to concentrate market power with global retailers. They have designed private standards that are meant to protect consumers from unsafe food and promote good agricultural practices abroad, as well as ethical trade. Yet, the increasing importance of south-south trade in agriculture and the global food crisis might again shift more power back to producers (Aerni 2009).

751-5110-00LInsects in AgroecosystemsW2 KP2VS. Halloran, K. Mauck
KurzbeschreibungThis class will focus on insect-plant interactions in Central European agroecosystems, and on regulators of insect pest populations. Lectures will cover important crop systems in central European agriculture. Within each system, major pests and their interactions will be described in an ecological context, focusing on key concepts in pest prediction and management.
LernzielAt the end of this course, students will have gained in-depth knowledge of the ecology of major pest species and their impacts within specific crop systems in Central Europe. Our approach will allow students to transfer this knowledge to related questions in other systems. Additionally, students will learn about current research goals in agroecology and how these goals are being addressed by scientists engaged in agricultural research.
InhaltInsect-plant interactions in middle European agroecosystems are the focus of this course. Always starting from an important perennial or annual crop, specific insect species of economic significance are presented along with the life cycles, population dynamics, and the insect-plant interactions relevant to economic impacts on the crop. Natural factors which limit such damage are introduced, e.g. parasitoids and predators. Each section of the course is complemented by a basic ecological, biological or engineering theme or approach such as host shift, physiological time, or sampling techniques. Recent advances in research will also be addressed throughout the course and reinforced with periodic readings of recent primary literature.

751-3404-00LNutrient Fluxes in Soil-Plant SystemsW4 KP4GA. Oberson Dräyer, E. K. Bünemann König
KurzbeschreibungDer Kurs vermittelt Fachwissen und experimentelle Techniken um Nährstoffflüsse in Boden-Pflanzen-Systemen zu untersuchen. Es werden Methoden erlernt um i) die Nährstoffdynamik, ii) die Ausnutzungseffizienz von Nährstoffen durch Pflanzen iii) das Schicksal von Düngernährstoffen die nicht durch Pflanzen aufgenommen werden und iv) symbiotische N2-Fixierung von Leguminosen zu untersuchen.
LernzielAm Beispiel des Elementes Stickstoff (N) werden die Studierenden mit Techniken vertraut, welche der Untersuchung der Dynamik und der Verfügbarkeit von Elementen im Boden-Pflanzensystem dienen. Die Studierenden erlernen die Anwendung von stabilen Isotopen zwecks Erfassung von Nährstoffflüssen in Boden-Pflanzensystemen. Sie lernen biochemische Methoden kennen, welche Indikatoren zu Nährstoffflüssen liefern. Die Studierenden werden befähigt, die Ansätze, Ergebnisse und die Interpretation von agronomischen und umweltwissenschaftlichen Studien kritisch zu überprüfen. Das Fachwissen über Prozesse und Kompartimente, welche Nährstoffkreisläufen in Boden-Pflanzensystemen zu Grunde liegen, wird vertieft.
Die Studierenden lernen im Labor in einem kleinen Team zu arbeiten, Arbeit in Gruppen zu organisieren, Informationen auszutauschen, Information ausserhalb des Kurses zu beschaffen (z.B. in der Bibliothek, im Internet), diese Informationen kritisch zu lesen und zu analysieren, und die Ergebnisse ihrer Experimente mit den Informationen anderer Quellen zu verbinden. Die mündliche und schriftliche Präsentation von Ergebnissen wird geübt.
InhaltThis course teaches knowledge and methods to analyze the dynamics of elements in soil-plant systems and to determine the use efficiency by crops of nutrients added with mineral and organic fertilizers. It provides knowledge about various techniques (isotopic, chemical, biochemical) that can be used to evaluate
i) content of elements in fertilizers, soils and plants;
ii) availability of elements in soils and fertilizers for plants;
iii) transfer of elements from a fertilizer to a crop;
iv) symbiotic N2 fixation by legumes.
Nitrogen will be used as model case.
The course will start with the discussion of analytical results on elemental contents in an organic fertilizer (e.g. animal manure, plant material) that has previously been labeled with the isotope 15N. To test the N efficiency of this fertilizer, a pot experiment (glasshouse study) will be designed. It will include soils with different characteristics, two test plants and fertilization treatments including the 15N labeled organic fertilizer and appropriate reference treatments.
Soils will be characterized for basic chemical properties and for biochemical characteristics that are related to the N dynamics. Plants will be harvested and analyzed for their dry matter production, their N isotope composition and for elemental contents. From the direct (15N) labeling approach, the proportion of N in the plant derived from the added fertilizers and the percentage of added fertilizer recovered in plant material will be calculated. The 15N analyses in the soil and in the plant material after the crop cycle will allow drawing a balance of the added fertilizer and discussing N losses. The comparison of 15N excess in legume and non-legume test plants will demonstrate the use of the enriched dilution method to estimate symbiotic N2 fixation by the legume.

The experiments are discussed and carried out by the students supervised by group members (two senior scientists, PhDs, laboratory staff). The students carry out the data analysis and report their findings in a written report and in an oral presentation.

You will have basic knowledge on phenotyping and genotyping technologies, and know how to connect this information for quantitative trait loci (QTL) mapping and association analysis. Furthermore, you will be able to assess relationships among genotypes by means of multivariate statistics (e.g. cluster analysis) using genetic and phenotypic information.
InhaltThe course is organized in the following three modules:
Module 1: Phenotyping of plant breeding experiments in the field phenotyping platform (FIP) at Eschikon Field Station.
Module 2: Statistical evaluation of the assessed data in R
Module 3: Molecular breeding
The course will be held at Eschikon Field Station, where 12 computers will be available for exercises with R.
We will observe the development of crops planted in the unique filed phenotyping platform. The field part includes two full days (July 02/03) during the summer semester break. The dates are chosen to allow you assessing buckwheat and wheat plants at stages of development, when meaningful measurements can be taken. In case somebody can't attend the course at these two days for justified reasons, we will seek for an alternative exercise.
During the course, we will have a closer look at wheat and buckwheat.
In wheat, we aim to teach the basic skills of phenotyping of plant development. You will assess the development using the simple scoring method, to train your breeder's eyes. Furtheremore, you will use sensors and indices used in the novel Field Phenotyping Platform (FIP), such as normalized difference vegetation index (NDVI), thermography and multispectral sensing. At the end of the course you will be able to judge the advantages of the "NDV-eye" vs. your Breeder's eye.
With Buckwheat we aim to establish a breeding program at ETH which is mainly operated by students. Here we need your enthusiasm, experience and input in order to succeed. You will score different traits of agronomic importance during the field day in summer. At the end of the course you should be able to pick the best varieties to make crosses for a planned breeding program organized by you and your fellow students of subsequent semesters.
In the statistical part of the course (module 2), you will learn how to process your data using the statistic package R and ASREML-R. For example, you will use the data assessed in module 1 to calculate heritabilities by means of analysis of variance. This part requires a basic understanding of R as taught in "Experimental Design and Applied Statistics in Agroecosystem Science" as well as of quantitative genetics as taught in "Pflanzengenetik". However these courses are not mandatory to enroll in plant breeding.
In the third module, you will learn about the genetic toolbox that is available for molecular breeding. Starting with the latest developments in DNA marker and genotyping technologies, the basic principles of genetic linkage mapping and QTL analysis will be illustrated. Novel breeding concepts such as genomic selection or breeding by design will be explained, discussed and evaluated for their potential to accelerate breeding progress in different crop species.
Voraussetzungen / BesonderesYou need a Basic understanding of R as taught in "Experimental Design and Applied Statistics in Agroecosystem Science" as well as quantitative genetics as taught in "Pflanzengenetik". However these courses are not mandatory to enroll in plant breeding.

KurzbeschreibungIm 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
InhaltModern 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.
751-5118-00LGlobal Change Biology Information W2 KP2GH. Bugmann, N. Buchmann, C. Emmel, L. Hörtnagl
KurzbeschreibungThis course focuses on the effects of anthropogenic climate change as well as land use and land cover change on terrestrial systems. Our current understanding of the coupled human-environmental systems will be discussed, based on observations, experiments and modeling studies. Different management options for sustainable resource use, climate mitigation and adaptation will be studied.
LernzielStudents will understand consequences of global change at various spatial and temporal scales, be able to synthesize their knowledge in various disciplines in view of global change issues, know international and national treaties and negotiations concerning management and climate and land use/land cover change, and be able to evaluate different management options, including sustainable resource use and climate mitigation as well as adaptation options.

Students will learn to present scientific information to an audience of educated laymen by preparing an executive summary and an oral presentation to answer a specific scientific question. Students will get extensive feedback from teachers and peers. Thereby, students will also learn how to give constructive feedback to peers.
InhaltChanges in climate and land use are major issues that students will be faced with during their working life, independently of where they will work. Thus, an advanced understanding on how global change, biogeochemistry, land use practices, politics, and society interact is critical to act responsibly and work as agricultural or environmental scientists in the future.

Thus, during this course, the effects of global change (i.e., changes in climate, atmospheric chemistry as well as land use and land cover) on forest and agro-ecosystems will be presented and discussed. Effects on ecosystem structure, composition, productivity and biogeochemical cycling, but also on stability of production systems against disturbances will be addressed. Current scenarios and models for coupled human-environmental systems will be discussed. The advantages and disadvantages of different management options will be studied, including the sustainable resource use and climate mitigation as well as adaptation.
Voraussetzungen / BesonderesThis course is based on fundamental knowledge about plant ecophysiology, soil science, and ecology in general.
