Though the loss of biological diversity is an ecological phenomenon, it also has a social dimension. This makes the study of the social landscape, encompassing the multitude of perspectives and aspirations by different stakeholders, highly relevant for better navigating trade-offs between biodiversity conservation and other land use objectives. Engaging with and addressing contextual understandings of biodiversity is vital to develop socially palatable solutions for biodiversity loss. This dissertation, therefore, takes a place-based approach to studying biodiversity conservation trade-offs and seeks to understand how the perspectives and aspirations of different stakeholders shape them. First, it aims to identify shared viewpoints as ensembles of perceptions and meanings about human-nature relations and biodiversity. Second, it aims to understand how biodiversity is valued and constructed in stakeholders’ aspirations towards their landscape. To this end, a convergent mixed methods approach and case study design are used. Two cases were selected that face different underlying drivers of land-use change, resulting in loss of biodiversity. The Muttama Creek Catchment area is a farming landscape in south-eastern Australia where the ongoing intensification of agricultural production threatens native biodiversity. In the Spreewald Biosphere Reserve in north-eastern Germany, land abandonment and the resulting loss of the biodiversity-rich wet meadows presents a key challenge for biodiversity conservation. Narratives and discourses provide conceptual lenses through which the author studies biodiversity conservation trade-offs. Drawing on Q-methodology, this dissertation identifies biodiversity-production discourses for the first case study and cultural landscape narratives for the second case study. Moreover, based on a participatory futures approach, the Three Horizons Framework, it elicits narratives of change that highlight opportunities for biodiversity conservation in farming landscapes. The findings highlight that despite some overlap in how stakeholders perceive biodiversity, contrasting problem framings and different biodiversity priorities present hindrances to concerted action to protect biodiversity and for collaboration. The findings also identify shared values among stakeholders. However, there is polarity and contestation around the role and importance of biodiversity in rural development.
The food and land use system is one of the most important global economic sectors. At the same time, today's resource-intensive agricultural practices and the profit orientation in the food value chain lead to a loss of biological diversity and ecosystem services, high emissions, and social inequality - so-called negative externalities. From a scientific perspective, there is a broad consensus on the need to transform the current food system. This paper investigates the suitability of True Cost Accounting (TCA) as an approach to inte-grating positive and negative externalities into business decisions in the food and land use system, focusing on the retail sector due to its high market power and resulting influence on externalities along the entire food value chain. For this purpose, a qualitative study was con-ducted with sustainability managers of leading European food retail companies in terms of their annual turnover, sustainable finance experts, and political actors related to environmental and social policy. A sample of N=11 participants was interviewed about the emergence and meas-urement of externalities along the food value chain, the current and future relevance of knowing about externalities for food retail companies, and the market and policy framework necessary for the application of TCA. The data collected was evaluated using the method of qualitative content analysis according to Mayring. Findings show that TCA is a suitable method for capturing positive and negative external ef-fects along the food value chain and thus also for meeting the growing social, political, and financial demands for its sustainable orientation. At the same time, there are still some chal-lenges in the application of TCA, both from a theoretical and a practical point of view. The main challenges at present are the lack of a standardised methodology, data availability, and key performance indicators. Due to the focus on prices, margins and competitors, food retail groups, in particular, emphasise the risk of revenue and profit losses as well as customer churn when applying TCA. Hence, the introduction of TCA in the food and land use system requires the development of measures that are socially acceptable, backed by legal frameworks and promote the scientific development of the methodology. This offers the opportunity to create a level playing field, apply the polluter-pays principle to the entire value chain and support science in developing appropriate indicators as well as a TCA database. Food retail companies can benefit from addressing TCA at an early stage by analysing their value chain to initiate change processes early, identify risk raw materials and products, reduce negative externalities through targeted measures, sensitise customers to the issue and thus differentiate themselves from competitors.
Die negativen Auswirkungen des modernen Konsumverhaltens sind heute weithin bekannt. Dennoch ist insbesondere die Modebranche weiterhin durch sehr niedrige Preise, kurze Produktlebensdauer und Massenkonsum gekennzeichnet. Eine Veränderung des Konsumverhaltens in der breiten Bevölkerung hin zu einer Reduktion von Neukäufen, einer langen Nutzungsdauer der vorhandenen Kleidung und zum Kauf ökologisch und sozial verträglich hergestellter Produkte ist aber dringend notwendig. Ein wichtiger Erfolgsfaktor für die effektive Ansprache der Konsumierenden ist die Berücksichtigung handlungsrelevanter Persönlichkeitsmerkmale auf Seiten der Zielgruppe. Die wissenschaftliche Literatur zu Prädikatoren nachhaltiger Verhaltensweisen weist darauf hin, dass persönliche Werte eine wichtige Rolle für dessen Umsetzung spielen. Gleichzeitig wirkt sich insbesondere im Kleidungskonsum auch das Geschlecht bzw. Gender der Konsumierenden auf das Verhalten aus. Ausgehend von dieser Datenlage werden in dieser Arbeit drei Themen mit Relevanz für die Nachhaltigkeitsforschung - persönliche Werte, Geschlecht/Gender und nachhaltiger Kleidungskonsum - zusammengeführt und auf ihre komplexe Wirkungsbeziehung hin untersucht. Auf Grundlage von Fokusgruppeninterviews wird erforscht, welche individuellen Wertorientierungen sich in welcher Weise und welcher Konstellation positiv auf ein nachhaltiges Kleidungskonsumverhalten auswirken und welche geschlechterspezifischen Unterschiede hierbei erkennbar werden. Durch die Berücksichtigung persönlicher konsumrelevanter Motivatoren und deren individueller Ausprägung werden Potenziale für eine zielgerichtete Verstärkung nachhaltigen Konsumverhaltens in der breiten Bevölkerung aufgedeckt. Dazu werden (1) vier Wertorientierungen mit Einfluss auf nachhaltigen Kleidungskonsum identifiziert, (2) ihre kausale Beziehung zu nachhaltigem Kleidungkonsum analysiert, (3) die geschlechtlichen Unterschiede berücksichtigt und (4) mit Gender ein Ansatzpunkt für die Erklärung der gefundenen Unterschiede angeführt. Zur Aufarbeitung der Daten wird die fsQCA zur Untersuchung des Themas nachhaltiger Kleidungskonsum angewandt. Die Natur dieser Auswertungsmethode, welche statt kausaler unidirektionaler Zusammenhänge zwischen zwei Variablen Schnittmengen zwischen zwei oder mehr Phänomenen untersucht, trägt zu einer neuen Perspektive auf die Beziehung zwischen Werten und nachhaltigem Kleidungskonsum bei. Eine Forschungsleistung dieser Arbeit besteht darin, gerade das Zusammenspiel der verschiedenen Werte zu betrachten und damit ein tieferes Verständnis von wichtigen Einflussfaktoren für nachhaltigen Kleidungskonsum zu ermöglichen - ein Ansatz, der über die bisher existierenden Forschungserkenntnisse hinausgeht. Aus den gewonnenen Resultaten werden Handlungsempfehlungen für die Kommunikation von NGOs und Unternehmen mit nachhaltiger Ausrichtung abgeleitet, wie eine zielgerichtete Ansprache zur Intensitätssteigerung dieser bereits vorhandenen Bedingungen gestaltet werden kann.
Collaborative governance is a promising approach to address the difficult challenges of sustainability through global public and private partnerships between diverse actors of state, market and civil society. The textile and clothing industry is an excellent example where a variety of such initiatives have evolved to address the wicked sustainability challenges. However, the question arises whether collaborative governance actually leads to transformation. In this dissertation, the author therefore questions whether and how collaborative governance in the textile sector provides space for, or pathways to, sustainability transformation. In three scientific articles and this framework paper, the author uses a mixed-methods research approach and follows scholars of sustainability science towards transformation research. First, he conducts a systematic literature review on inter-organizational and governance partnerships before diving into a critical case study on an interactive collaborative governance initiative, the German Partnership for Sustainable Textiles (Textiles Partnership). The multi-stakeholder initiative (MSIs) was initiated by the German government in 2015 and brings together more than 130 organizations and companies from seven stakeholder groups. It aims at improving working conditions and reducing environmental impacts in global textile and clothing supply chains. In two empirical articles, the author then explores learning spaces in the partnership and the ways in which governance actors navigate the complex governance landscape. For the former, he uses a quantitative and qualitative social network analysis based on annual reports and qualitative interviews with diverse actors from the partnership. Then, he uses qualitative content analysis of the interviews, policy documents and conducts a focus group discussion to validate assumptions about the broader empirical governance landscape and the social interactions within. Finally, in this framework paper, he uses theories of transformation to distinguish forms of change and personal, political and practical spheres of transformation, and reflects on the findings of the three articles in this cumulative dissertation.
The dissertation consists of three scientific papers and a synopsis. The synopsis addresses the relevance of the dissertation and lists the key factors for the sustainability transition in the electricity system as a common denominator of the three papers. The relevance of the dissertation results, on the one hand, from the urgency of the sustainability transition in the electricity system and an insufficient transition willingness of the eastern European Member States. On the other hand, the Multi-Level-Perspective as one of the most important scientific frameworks to grasp transitions does not provide a sufficient explanation of its mechanisms. Moreover, Demand Response aggregators as new enterprises on the European electricity market and potential reform initiators are still under researched. The following key factors for the sustainability transition of the electricity system have been identified: supply security concerns, Europeanisation, policy making and the dominance of short-term oriented economic evaluation. Paper#1 sheds light on the roots of this problem in the context of Poland. It suggests that unfavorable regulation is symptomatic of the real, underlying barriers. In Poland, these barriers are coal dependence and political influence on energy enterprises. As main drivers, supply security concerns, EU regulatory pressure, and a positive cost-benefit profile of DR in comparison to alternatives, are revealed. A conceptual model of DR uptake in electricity systems is proposed. Applying a social mechanisms approach to the Multi-Level Perspective, paper#2 conceptualizes mechanisms of socio-technical transitions and of gaining legitimacy for transitions as co-evolutionary drivers and outcomes. Situational, action-formational, and transformational mechanisms that operate as drivers of change in a socio-technical transition require corresponding framing and framing contests to achieve legitimacy for that transition. The study illustrates the conceptual insight with the case of the coal dependent Polish electricity system. Paper #3, a qualitative study reveals Demand Response (DR) aggregators as institutional entrepreneurs that struggle to reform the still largely supply-oriented European electricity market. Unfavourable regulation, low value of flexibility, resource constraints, complexity, and customer acquisition are the key challenges DR aggregators face. To overcome them they apply a combination of strategies: lobbying, market education, technological proficiency, and upscaling the business. The study highlights DR aggregation as an architectural innovation that alters the interplay between key actors of the electricity system and provides policy recommendations including the necessity to assess the real value of DR in comparison to other flexibility sources by taking all externalities into account, a technology-neutral approach to market design and the need for simplification of DR programmes, and common standards to reduce complexity and uncertainty for DR providers.
The aim of this paper is to determine how a carbon footprint label for grocery products can be designed to facilitate a sustainable consumption behaviour. Therefore, a mixed-method approach was used consisting out of a review of relevant literature and an explorative quantitative survey with n=158 participants. It was found that consumers generally have a positive attitude towards carbon labelling, but they lack understanding of the term, its underlying concepts and the emissions caused by grocery products. In regard to the design criteria of a carbon label, labels with a coloured scale are preferred most by consumers. Also, the mechanisms of consumer behaviour imply that not all parts of the behaviour are visible and controllable for individuals themselves. The concluding concept proposal summarises important criteria of a carbon labelling system that has the goal to educate consumers and facilitate a lower carbon consumption behaviour, such as a simple visual design, the use of a colour scale, a design enabling a comparison, the provision of a link to further information, the public enforcement of the system and overall uniformity.
Despite growing research on sustainability transformations, our understanding of how transformative transdisciplinary research can support local actors who foster change towards sustainability is still somewhat limited. To contribute to this research question, the investigator conducted research in a transdisciplinary case study in Southern Transylvania, where non-governmental organizations (NGO) drive sustainability initiatives to foster desired changes (e.g., supporting small-scale farmers or conserving natural and cultural heritage). Interactions with these local actors and reflections on the research question shaped the research of this dissertation. In paper 1, the author conducted a literature review on amplification processes that describe actions, which local actors can apply to increase the impact of their sustainability initiatives. In paper 2, he conducted a literature review on the application of indigenous and local knowledge (ILK) in sustainability transformations research to understand whether this research engages with the conceptualization of transformations from local actors. The results show that ILK is generally applied to confirm and complement scientific knowledge in contexts of environmental, climate, social-ecological, and species change. In paper 3, the author derived principles that provide guidance for how to integrate sustainability initiatives from local actors in transformative transdisciplinary research. Based on his transdisciplinary research with the NGOs in Southern Transylvania and by using systems and futures thinking as an approach for analysis, he derived three principles that provide guidance for the co-design of sustainability intervention strategies that build on, strengthen, and complement existing initiatives from local actors. In paper 4, the author explored empirically how to identify relevant local actors for collaborations that seek to intervene in specific characteristics of a system (e.g., parameters or design of a system). He applied a leverage points' perspective to analyse the social networks of the NGOs in Southern Transylvania that amplify the impact of their initiatives. This dissertation as a whole contributes insights to three recommendations of how transformative transdisciplinary research can support local actors fostering change towards sustainability: First, by conducting research that studies and supports local actors who increase the impact of their sustainability initiatives via amplification processes (Paper 1 and 4); Second, by engaging specifically with the initiatives, networks, and knowledge from local actors, who foster bottom-up, place-based transformations (Paper 1-4); Third, by identifying and collaborating with local actors that are relevant for strategic systems interventions that build on, strengthen, and complement existing initiatives (Paper 3-4).
Gentechnische Anwendungen werden in den USA über einen vertikalen Verfahrensansatz geregelt, der meist zu einer Gleichbehandlung konventioneller und genetisch veränderter Lebens- und Futtermittel führt. Im Gegensatz dazu resultiert die strengere europäische Regulierung mit ihrem horizontalen Verfahrensansatz in einer grundsätzlichen Unterscheidung konventioneller und genetisch veränderter Lebens- und Futtermittel. Diese Unterschiede bergen im Kontext bilateraler Handelsabkommen ein erhebliches Konfliktpotential, das sich durch die derzeit in Verhandlung stehende Transatlantische Handels- und Investitionspartnerschaft noch verschärfen könnte. Trotz starker Geheimhaltung zeichnet sich ab, dass in dem Abkommen der vertikale Verfahrensansatz bevorzugt wird. In Verbindung mit den ebenfalls diskutierten Investor-Staat-Schiedsgerichten könnte dies langfristig die europäischen Gentechnikregulierungen aufweichen oder mit hohen Klagen auf Schadenersatz von US-amerikanischen Investoren einhergehen.
It is understood among research and policy makers that addressing unsustainable individual consumption patterns is key for the vision of sustainable development. Education for Sustainable Consumption (ESC) is attributed a pivotal role for this purpose, aiming to improve the capacity of individuals to connect to and act upon knowledge, values and skills in order to respond successfully and purposefully to the demands of sustainable consumption. Yet despite political, scientific, and educational efforts and increasing awareness in the general population, little has been achieved to substantially change behavioral patterns so far. As part of the explanation for this shortcoming, it has been argued that current ESC practices have neglected the personal dimension of sustainable consumption, especially the affective-motivational processes underlying unsustainable consumption patterns. Against this background, this cumulative thesis is guided by the question how personal competencies for sustainable consumption can be defined, observed, and developed within educational settings. Special attention is given to mindfulness practices, describing the practice of cultivating a deliberate, unbiased and openhearted awareness of perceptible experience in the present moment. Drawing upon an explorative, qualitative research methodology, the thesis looks at three different mindfulness-based interventions aiming to stimulate competencies for sustainable consumption, reaching out to a total number of 321 participants (employees and university students). In this thesis, the author suggests to define personal competencies for sustainable consumption as abilities, proficiencies, or skills related to inner states and processes that can be considered necessary or sufficient to engage with sustainable consumption (SC). These include ethics, self-awareness, emotional resilience, selfcare, access to and cultivation of personal resources, access to and cultivation of ethical qualities, and mindsets for sustainability. The thesis holds that the observation of personal competencies benefits from a combination of different methodological and methodical angles. When working with self-reports as empirical data, a pluralistic qualitative methods approach can help overcoming shortcomings that are specifically related to individual methods while increasing the self-reflexivity of the research. Moreover, it is suggested to let learners analyze their own personal statements in groups, applying scientific methods. The products of the group analyses represent data based on an inter-subjectively shared perspective of learners that goes beyond self-estimation of personal competencies. In terms of developing personal competencies for SC, it can be concluded that mindfulness practice alone is not sufficient to build personal competencies for SC. While it can stimulate generic personal competencies, individuals do not necessarily apply these competencies within the domain of their consumption. Nevertheless, mindfulness practice can play an important role in ESC, insofar as it lays the inner foundation to engage with sustainability-related issues. More precisely, it allows learners to experience the relevance of their inner states and processes and the influence they have on actual behaviors, leading to a level of selfawareness that would not be accessible solely through discursive-intellectual means. Furthermore, participants experience mindfulness practice as a way to develop ethical qualities and access psychological resources, entailing stronger emotional resilience and improved well-being. In order to unleash its full potential for stimulating personal competencies for SC, however, the findings of the thesis suggest that mindfulness practice should be (a) complemented with methodically controlled self-inquiry and (b) related to a specific behavioral change. In this vein, self-inquiry-based and self-experience-based learning – two pedagogical approaches developed during the period of research for this thesis – turned out to be promising pedagogies for educational settings striving to stimulate the development of personal competencies for SC.
In dieser Arbeit wird das Thema der Überfischung vor der Küste Westafrikas behandelt. Der Schwerpunkt liegt auf der industriellen und auf der illegalen Fischerei, welche hauptsächlich von den Industrienationen ausgehen. Hierbei werden die Rechtslage und die Auswirkungen auf die Ökonomie und die Soziologie in Westafrika behandelt. Im Hinblick
auf die intensive Fischerei lautet die zentrale Frage, ob die industrielle und die illegale Fischerei zu einem Zusammenbruch des Fischereisektors in Westafrika führen. Fazit der Arbeit ist, dass die lokalen Fischer und die Arbeiter aus den Weiterverarbeitungsbetrieben massiven Existenzproblemen ausgesetzt sind. Des Weiteren führt der Mangel an Fischereiprodukten zu einer Vielzahl von Problemen in der Bevölkerung, als Beispiel ist hier die Mangelernährung zu nennen. Den Abschluss dieser Arbeit bilden umfassende Lösungsvorschläge aus den Bereichen Recht, Politik und
Sozialwissenschaften.
