Entwicklung und Erprobung einer kognitiv-sensorischen Methodik für die Erhöhung der Reliabilität von erhobenen Daten in Bezug auf Nachhaltigkeit und Konsumentenverhalten in Deutschland und in der Ukraine
(2023)
Die menschlichen Sinne werden als Brücke zwischen der Mitwelt und dem menschlichen Körper sowie als entscheidender Faktor bei der Bildung von Ernährungserfahrungen beginnend schon im Mutterleib betrachtet. Diese Studie zielt darauf ab, wissenschaftlich zu untersuchen, wie der Wandel hin zu einer nachhaltigen Ernährung unterstützt werden kann, indem das Konsumentenverhalten sowie deren Flexibilität und Änderungsbereitschaft mithilfe einer neuen kognitiv-sensorischen Methode bewertet und bemessen wird.

Lignocellulosic biorefinery with a thermo-biological pretreatment concept
(2023)
There is great interest, not only in technologically advanced societies, in developing innovative sources of raw materials, especially lignocellulosic biomasses such as cereal straw, which do not interfere with food production. In Germany, 4 – 9 million tons of cereal straw, mainly wheat, are utilized annually, corresponding to an energy potential of 57 – 129 PJ/a. Lignocellulose, found in plant cell walls, consists of hemicellulose, cellulose, and lignin, and it requires complex fractionation to enable its polymers ...

Yield performance and weed control efficiency of organically managed silage maize double cropping systems
(2023)
Maize is among the three most important crops worldwide, while its multifunctional nature allows a diversified use. However, the traditional (silage) maize production often has negative side-effects related to the unprotected soil surface — e.g., erosion, weed pressure and related mechanical weed control. There are several alternative management systems to enhance the sustainability of (silage) maize production. However, the means and strength of influence are still unclear in some cases. Therefore, the current thesis ...

Management effects on soil microbial functions at a South-Indian rural-urban interface
(2023-06)
Urbanization leads to effects on many aspects of ecosystems and societies. Among the affected are agricultural systems and, specifically, soils. One of the most evident pathways of urbanization effects on agricultural soils is through an increased demand for agricultural commodities requiring agricultural intensification, hence, changes in management practices that alter soils.
In this context, the purpose of this study was to understand how the main agricultural management practices taking place in urbanizing ...

Implementation of targettarget-orientated approaches in antibiotic and homeopathic treatment of acute bovine clinical mastitis in dairy practice
(2022-07)
Diese kumulative Dissertation hatte das übergeordnete Ziel Rahmenbedingungen (Voraussetzungen) für einen hohen Behandlungserfolg bei der antibiotischen und homöopathischen Mastitistherapie auf Milchviehbetrieben zu identifizieren sowie mögliche Optionen zur Erhöhung der Heilungsraten zu ermitteln. Darüber hinaus wurde die Steigerung des Behandlungserfolges unter der Maßgabe eines reduzierten Antibiotikaverbrauchs untersucht.

Entwicklung eines innovativen Produktionsverfahrens für die Herstellung von Wurstwaren ohne Verwendung von Zusatzstoffen
(2023)
Das Ziel der vorliegenden wissenschaftlichen Untersuchungen ist die Entwicklung von Produktionsverfahren für Brüh- und Frischwurst ohne die Verwendung von Nitritpökelsalz und anderen Zusatzstoffen, die mittels Angaben von E-Nummern deklariert werden müssen. Am Beispiel von Bio-Lyoner in Dosen und Bio-Edelsalami wurden im Rahmen eines F&E-Vorhabens, welches unter Praxisbedingungen bei der Bäuerlichen Erzeugergemeinschaft Schwäbisch Hall (BESH) durchgeführt wurde, innovative Produktionsverfahren entwickelt und auf ihre ...
Dissertation
Using Optical Satellite Imagery to Monitor and Understand Agricultural Land-cover Change
(2020-06)
The activities of humans have transformed the earth over the last decades. The transformation is estimated to increase further in response to the growing world population. This has caused many countries to devise means to utilize resources sustainably. Bio-economy is seen as a means to reduce the high reliance on fossil materials and ensure the provision of raw materials, energy and food to the increasing world population in a sustainable manner. However, the rising demands for biomass to produce bioenergy have relied ...

Robustness of portable and laboratory-based visible/near- and mid-infrared spectroscopy for optimized determination of temporally and spatially variable soil properties
(2021)
Application of visible/near- (VISNIRS) and mid-infrared (MIRS) spectroscopy to the field of soil science is promising, as it allows information about a range of properties to be collected simultaneously and rapidly, thereby providing high spatial and temporal resolution data for use in, e.g., soil mapping, precision agriculture, and long-term monitoring. However, investigation of the conditions under which visNIRS and MIRS can replace traditional lab methods is required, as the accuracy, robustness, and efficiency ...

Food commercialization, hidden hunger and malnutrition: A study of food and nutrition security, focusing on the marginalized society in Sri Lanka
(2020-09)
From 2016 to 2019, a collaborative research project between the Rajarata University of Sri Lanka and the Department of Organic Food Quality and Food Culture, University of Kassel, Germany, was carried out to investigate the food commercialization, hidden hunger, and malnutrition in marginalized societies in Sri Lanka.
Consuming a healthy diet, maintaining good health, and chronic diseases is a challenge for those struggling with poverty and food insecurity for various reasons in Sri Lanka, including limited financial ...

Sustainable diets: Studies on German consumers’ intention-behavior gap
(2020-01)
Globally our practiced food systems are causing great harm to our environment including contributions to biodiversity loss, soil degradation, water pollution, and climate change, as well as to human health. Sustainable diets are crucial for solving those global diet-related problems because they are credited with a key role in the transformation of our currently practiced food systems into more sustainable ones. Increasing the practice of sustainable diets can be a starting point for initiating the needed change. ...
