Dimensionierung und Gestaltung von Laufställen für behornte Milchkühe unter Berücksichtigung des Herdenmanagements
(2011-11-23)
Die Haltung von Milchkühen in einem Laufstall hat sich aus arbeitswirtschaftlichen und Kostengründen stark verbreitet. Im Biolandbau wird diese Entwicklung vor allem aufgrund der höheren Tiergerechtheit dieser Haltungsform forciert. Gleichzeitig werden die allermeisten Kühe für die Laufstallhaltung jedoch enthornt, unter anderem weil sich in den üblichen Ställen mit Normmassen und –konzepten Probleme mit Verletzungen unter den Tieren ergaben. Dabei sprechen die Richtlinien und Verordnungen für biologisch wirtschaftende ...

Human and Raptor Interactions in the Context of a Nomadic Society
(kassel university press, 2015)
This research project focuses on contemporary eagle-taming falconry practice of the Altaic Kazakhs animal herding society in Bayan Ulgii Province in Western Mongolia. It aims to contributing both theoretical and empirical criteria for cultural preservation of Asian falconry. This cultural as well as environmental discourse is illustrated with concentrated field research framed by ecological anthropology and ethno-ornithology from the viewpoint of “Human-Animal Interaction (HAI)” and “Human-Animal Behavior (HAB)”.

De la désorganisation à l’organisation apprenante en milieu rural
(2015-11-13)
ZUSAMMENFASSUNG
Von der „Chaosgruppe“ zur lernenden Organisation.
Fallstudien zur Induzierung und Verbreitung von Innovation in ländlichen Kleinorganisationen im Buruli (Zentral-Uganda).
Die oft fehlende Nachhaltigkeit landwirtschaftlicher Projekte in Afrika allgemein und in Buruli (Zentral-Uganda) insbesondere gab den Anstoß zu der Forschung, die der vorliegenden Dissertation zugrunde liegt. Ein häufiger Grund für das Scheitern von Projekten ist, dass die lokale Bevölkerung die landwirtschaftliche Innovation ...

Analyse von unerwünschten Arzneimittelwirkungen antibiotikahaltiger Euterinjektoren von Mastitiden bei Kühen der Rasse Holstein- Friesian unter Berücksichtigung von Leistungsniveau, Genetik und Produktionsbedingungen
(2015-08-04)
Das Ziel der vorliegenden Arbeit bestand darin, detailliert Wechselwirkungen zwischen dem binären Gesundheitsmerkmal klinischer Mastitis auf der einen und Produktionsmerkmalen (z. B. Milch-kg) und funktionalen Merkmalen (z.B. somatischer Zellgehalt) auf der anderen Seite unter simultaner Berücksichtigung von Umwelt und genetisch bedingten Einflussgrößen auf phänotypischer und genetischer Ebene abzubilden. Die Studie fokussierte auf innovative Aspekte der genetisch-statistischen Modellierung bzgl. der Anwendung von ...

Factors influencing the purchase behaviour of consumers for organic wine: An analysis of household panel data
(2018-07-19)
Consumer studies based on surveys and purchase experiments show positive attitudes towards organic wine in large consumer segments. However, the market share of organic wine is still small. Apparently, there is a gap between consumer attitudes and real purchase behaviour but no study so far analysed this attitude-behaviour relation in a real market context. Therefore, the present dissertation is based on real market data – household panel data of the GfK (Gesellschaft für Konsumforschung).
The study revealed low ...

Potentials and limits of sustainability communication - The cases of climate-friendly food and farmed fish
(2018-02-15)
The present thesis focuses on the potentials and limits of sustainability communication via media, labels and claims to foster the consumption of climate-friendly food and sustainably farmed fish. A mixed methods approach combining an online survey containing choice experiments with qualitative face-to-face interviews was applied to explore consumers’ perceptions of climate-friendly food as well as the limits and merits of a carbon footprint label for fostering climate-friendly consumption. The qualitative approach ...

Heat stress response for physiological traits in dairy and dual purpose cattle populations on phenotypic and genetic scales
(2016-02-23)
The main objective of this thesis was to determine the potential impact of heat stress (HS) on physiological traits of lactating cows and semen quality of bulls kept in a temperate climate. The thesis is comprised of three studies. An innovative statistical modeling aspect common to all three studies was the application of random regression methodology (RRM) to study the phenotypic and genetic trajectory of traits in dependency of a continuous temperature humidity index (THI).
In the first study, semen quality and ...

Linking sustainable diets to the concept of food system sustainability
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Based on insights from an ongoing research project on food sustainability, we argue that discussing sustainable diets in isolation from food systems poses risks. Among these risks are making healthy diets exclusive, or ignoring externalities like biodiversity loss, land concentration, and encroachment on commons. Case studies from Bolivia and Kenya show how marked shifts from traditional to more uniform diets rich in sugar, salt, and fatty acids come with a radical transformation of food systems. Systems formerly ...

Seaweed farming as a sustainable livelihood option for northern coastal communities in Sri Lanka
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-10-09)
Sri Lanka has recently contributed to the growing significance of seaweed farming in the globe. This study attempted to assess the financial feasibility, employment generation, perceived importance, social acceptability and major constraints associated with seaweed farming in the Northern part of Sri Lanka. The study sample included 160 seaweed farmers from the area. A questionnaire survey, in-depth interviews and focus group discussions were conducted to collect data and information. Descriptive analytical, investment ...
Dissertation
The prediction of seasonal and inter-annual climate variations and their impacts on the water resources in the eastern seaboard of Thailand
(2015-04-27)
The research of this thesis dissertation covers developments and applications of short-and long-term climate predictions. The short-term prediction emphasizes monthly and seasonal climate, i.e. forecasting from up to the next month over a season to up to a year or so. The long-term predictions pertain to the analysis of inter-annual- and decadal climate variations over the whole 21st century. These two climate prediction methods are validated and applied in the study area, namely, Khlong Yai (KY) water basin located ...
