The relation of food business with nature – an investigation of ecological accounts of the food industry
(2021)
Unternehmen sind angehalten, freiwillig oder gesetzlich, für ihre Handlungen Rechenschaft abzulegen. Nachhaltigkeitsberichte (Engl. sustainability reports oder ecological accounts) sind ein Weg aufzuzeigen, inwiefern sich unternehmerische Entscheidungen auf die soziale und ökologische Umwelt auswirken. Der Grund für die Untersuchung solcher ecological accounts im Rahmen dieser Dissertationsschrift ist der Einfluss von Lebensmittelunternehmen auf die soziale und natürliche Umwelt. Das Forschungsziel dieser Arbeit ist ...

Was steht dem Wissenstransfer zur Tiergesundheit in der landwirtschaftlichen Nutztierhaltung entgegen?
(2021-09)
Produktionskrankheiten sind (auch in der ökologischen) Nutztierhaltung weit verbreitet und werden in der Gesellschaft zunehmend als negativer externer Effekt wahrgenommen. Sie führen zum Einsatz von Antibiotika, sind Ausdruck eines beeinträchtigten Tierwohls und verursachen den landwirtschaftlichen Betrieben Ausfallkosten. Obwohl zu den Ursachen und der Vorbeugung viel geforscht wurde sind Produktionskrankheiten weit verbreitet. Ziel der vorliegenden Arbeit war es, den mit dem Begriff Wissenstransfer beschriebenen ...

Untersuchung von Farbspektren und deren Zusammenhang mit anderen Produkteigenschaften bei unterschiedlichen Trocknungsprozessen von Lebensmitteln
(2021)
Zur Erfassung von Veränderungen der Produkteigenschaften während der Trocknung von Lebensmitteln werden zerstörungsfreie Qualitätsmesstechniken gefordert, mit denen Veränderungen im Inneren des Produkts bestimmt werden können. Gerade im industriellen Einsatz sind schnelle, präzise, und gleichzeitig robuste Verfahren besonders wichtig, um qualitativ hochwertige Produkte zu erhalten.
In dieser Arbeit wurde zur optischen Qualitätsmessung ein neuartiges multispektrales Kamerasystem eingesetzt, um von Veränderungen der ...

Optimisation of the seedball technology for sorghum production under nutrient limitations
(2021-04-13)
The seedball technology is a simple and affordable seed-pelleting technique that uses locally available materials such as sand, loam, wood ash and seeds to enhance early crop establishment. It has been shown to be effective for pearl millet (Pennisetum glaucum) subsistence production in Sahelian environments. The objective of this study was to optimise the seedball technology for sorghum (Sorghum bicolor (L.) Moench) under greenhouse conditions. Series of pot experiments were conducted in order to identify optimal ...

Determinants of protected tomato production technologies among smallholder peri-urban producers in Kiambu, Kenya
(2021-03-05)
Climate variability and the rise in incidences of pests and diseases continue to undermine production of high value vegetables among smallholder farmers in sub-Saharan Africa. In order to respond to these challenges, protected farming technologies (PFT) (such as greenhouses) which modify the plant environment and therefore aid in avoiding the harmful eects of climatic factors have been promoted. Greenhouses protect the crops against high solar radiation and heavy rainfall that have the potential of destroying vulnerable ...

Governance for Decent Work in Agricultural Globalisation
(2021)
In the past decades, the agricultural world has become smaller as international food businesses have become organised around a global production network. One of the main factors for the introduction of a more decentralised and flexible food and agricultural system was the wage difference between Global North and Global South actors. In addition, Global South countries have facilitated the spread of Global Agricultural Value Chain/Global Agricultural Production Networks (GAVC/GAPNs) through promoting export processing ...

Diversification of maize-based intercropping systems in tropical rainforest agroecosystem of Nigeria: productivity, profitability and soil fertility
(2021-02-07)
Monocropping of maize is becoming unsustainable in the rainforest agroecosystem of Nigeria. This is due to the adverse impact of climate change such as increasing pests and disease infestations and erratic rainfall patterns coupled with underutilization of resources. Smallholder farmers in this tropical agroecosystems are in dire need of adaptive and resilient cropping systems to ensure food, nutrition, and livelihood security. Thus, this study aims to identify adaptive maize-based systems for the rainforest agroecology ...
