Land tenure in a changing climate
(2023)
Climate change and extreme weather have far-reaching impacts on agriculture. They do not only affect agricultural production, but also fundamental assets that shape agricultural livelihoods. In this dissertation, I study the relation of weather and climate with agricultural land tenure in low- and middle-income countries. Secure access to land is of vital importance for farmers, but insecure tenure is a reality for millions of farmers around the globe. They are unsure whether they will be able to continue farming ...

Industry 4.0-driven additive manufacturing for operations in the circular economy
(2023-06)
This dissertation focuses on exploring how key elements of Industry 4.0 (I4.0), such as additive manufacturing (AM) and quantitative techniques/simulation, instigate the operations of an organisation towards the circular economy (CE). AM represents the technological foundation of future manufacturing which efficiently utilises materials avoiding unnecessary waste. Further, it could positively impact the transition towards CE by addressing issues related to the operations and supply chains while positively influencing ...

Managing Collaboration in Circular Supply Chains
(2023-05)
The dissertation focuses on understanding the application of the circular economy (CE) concept to the supply chain management (SCM) domain as ‘circular supply chains’ (CSCs) and the role of collaboration in this application. While CE is an emerging approach for sustainable production and consumption, its application in the SCM domain as CSCs could assist in improving the overall sustainable performance. Collaboration with internal and external partners is crucial to achieve this improvement. Hence, with the aim to ...

Herausforderungen bei der Analyse von Unterrichtsqualität und deren Wirkungen auf Lernende
(2023-07)
Die empirische Unterrichtsforschung stellt Forschende vor zahlreiche Herausforderungen. Eine besondere Herausforderung besteht darin, dass wissenschaftliche Ergebnisse in hohem Maße von den Entscheidungen der Forschenden im Forschungsprozess abhängen – ein informiertes Vorgehen ist für jeden Schritt guter wissenschaftlicher Forschung fundamental. Ziel der kumulativen Dissertation ist es daher, aus einer Metaperspektive theoretisch-konzeptionelle Grundlagen und forschungsmethodische Fragen der Unterrichtsforschung zu ...

Analysis of agricultural landscape transformation and cropping system diversification in southern Myanmar
(2023)
Myanmar's forests are rich in biodiversity and have significant potential for carbon reduction. Kyunsu Township in southern Myanmar is still covered by biodiverse tropical evergreen rainforests on the highlands and mangroves on the coastline, conserving carbon stocks. However, the expansion of croplands into these forests to meet the growing demand for food and crop income is a major driver of deforestation and loss of carbon sinks. Thus, balancing agricultural land use and natural resource conservation is vital for ...

Management factors influencing cow milk quality and safety in the Indian megacity of Bengaluru
(2023)
Ensuring animal welfare is a critical priority for livestock farmers in the face of urbanization. Rapid urban growth increases the demand for animal products but decreases availability of arable land around cities with negative implications for animal feed production. In urbanizing regions, livestock keepers resort to common pool resources for animal nutrition. Yet, the repercussions of urbanization on the quality of common pool feed resources, animal health, production and product safety, remain unstudied. Additionally, ...

Transforming towards a sustainable circular economy: exploring the social dimension, actor contribution and emerging paradoxes
(2023)
Pressing global societal challenges highlight organisational vulnerability and the need to transform towards more sustainable production and consumption measures. The circular economy concept is considered an alternative to the prevalent linear economic system. It aims to contribute to sustainable development by slowing and closing resource cycles and facilitating cross-sectoral collaboration of multiple stakeholders. Yet, the desired transformation is lagging behind and the current debate focuses primarily on the ...

The role of sustainability in capital markets
(2023)
This doctoral thesis explores capital market sustainability, focusing on the European capital market.
The work takes two different angles, either from the investors perspective while subsequently examining if reported ESG activities and an ESG rating's sustainability performance affect a company's valuation or risk.

Denaturation mechanism of whey protein by using the hot extrusion technology
(2022-02)
Milk proteins are one of the heat-sensitive nutritional components, especially whey proteins changing their structure through thermal treatment, consequently denaturizing and aggregating. The transformation of native whey proteins structure in presence of shear stress resulted in the microparticulation, which affected the functional properties. Many authors investigated these parameters with different conditions; however, understanding the combination of relevant parameters of the microparticulation process of whey ...
