The industrial food system is by far the largest greenhouse gas emitting sector. It causes significant damage to terrestrial, aerial and aquatic ecosystems, negative health impacts and an unfair distribution of economic benefits. The call for sustainability transformations is growing, entailing and promoting radical shifts in industrial food systems that lead to new patterns of interactions and balanced social, economic and ecological outcomes. While traditional research has focused on sustainability problems in the food system, it lacks evidence on solutions and desired future states; and more so, on how to practically move from the current to the desired state. Food forests present a promising solution to address multiple sustainability challenges adaptable to local contexts. As biodiverse multi-strata agroforestry systems, they can provide several ecological, socio-cultural and economic services. They sequester carbon, limit soil erosion and regulate the micro-climate; they offer the opportunity for education on healthy diets and ecology, and they produce food and can create livelihood opportunities. However, despite their obvious benefits and a trend in uptake, food forests are still a niche concept rarely known in mainstream culture. To date, research has focused on their ecological and social services; we lack an understanding of food forests as a comprehensive sustainability solution, including their economic dimension, and knowledge on how to develop them. Addressing these gaps, this qualitative research used a solution- and process-oriented methodology guided by transformational sustainability research. In a comparative case study approach, it created an inventory of 209 food forests, followed by interviews and site visits of 14 sites to understand their characteristics and assess their sustainability (Article 1). More indepth, it analyzed the implementation path of seven food forest for success factors, barriers and coping strategies (Article 2). Based on these insights, two experimental case studies were initiated to develop sustainable food forests with practice partners, one based in Phoenix, Arizona, U.S. and one in Lüneburg, Germany. Two studies analyzed the cases’outputs and processes highlighting success factors and challenges, including the role of a sustainable entrepreneurial ecosystem (Article 3, Phoenix case) and key features of productive partnerships to understand why one case succeeded and the other failed (Article 4). Findings include key features of existing and sustainable food forests as well as success factors on how to develop them; namely acquiring a complementary skill set that includes specialty farming and entrepreneurial know-how, securing sufficient start-up funds and long-term land access as well as overcoming regulatory restrictions. Supporting institutions are especially needed to integrate and professionalize the planning stage and provide know-how on alternative business practices. Key features of productive partnerships include an entrepreneurial attitude, access to support functions, long-term orientation and commitment to food system sustainability. The synthesis provides a detailed, ideal-typical implementation pathway to develop sustainable food forests and relevant supportive actors. This study provides researchers, food entrepreneurs, public officials, and activists with insights on how to develop and advance food forests as a sustainability solution.
Viable communication systems
(2020)
Since the middle of the 20th century, human society experiences a “Great Acceleration” manifesting in historically remarkable growth rates that create severe sustainability problems. The globally exploding potentials of information and knowledge exchange have been and are vital drivers for this acceleration. Society has now come to the point that it requires a “Great Transformation” towards sustainability to ensure the viability of the planet for a vital society. The energy transition plays a central role for this transformation. In this context, human society has developed a comparably good understanding of the necessary infrastructural changes of this transition. For transforming the patterns of energy production and use in an energy transition as part of the “Great Transformation”, this process of change now needs to strengthen its focus on information, communication, and knowledge systems. Human society needs to establish a knowledge system that has the potential to create usable knowledge for sustainability solutions. This requires organizing a communication system that is sufficiently complex, interconnected, and, at the same time, efficient for integrating reflexive, open-ended, inter- and transdisciplinary learning, evaluation, and knowledge co-production processes across multiple levels. This challenge opens a wide field of research.
This cumulative dissertation contributes to research in this direction by applying a systemic sustainability perspective on the content and organization of communication in the field of research on sustainable energy and the operational level of municipal climate action as part of the energy transition. Regarding sustainability, this thesis uses strong sustainability and its principles as a frame for evaluating the content of communication. Regarding the systemic perspective, the thesis particularly relies on the following theories: (i) the human-environment system model by R. Scholz as an overarching framework regarding interactions between humans and nature, (ii) social systems theory by N. Luhmann to reflect the complexity of society, (iii) knowledge management to consider the human character of knowledge and a practice-oriented perspective, and (iv) management cybernetics, in particular, the Viable System Model by S. Beer as a framework to analyze and assess organizational structures. Furthermore, the thesis leverages the potential of text mining as a method to identify and visualize patterns in texts that reflect prevalent paradigms in communication.
The thesis applies the above conceptual and methodological basis in three case studies. Case Study 1 investigates the measures proposed in 16 municipal climate action plans of regional centers in Lower Saxony, Germany. It uses a text mining approach in the form of an Summary interpretation network analysis. It analyzes how different societal subsystems are connected at the semantic level and to what extent sustainability principles can be recognized. Case Study 2 analyzes and reflects paradigms and discursive network structures in international scientific publications on sustainable energy. The study investigates 26533 abstracts published from 1990 to 2016 using a text mining approach, in particular topic modeling via latent Dirichlet allocation. Case Study 3 turns again to the cases of municipal climate action in Lower Saxony examined in Case Study 1. It examines the involvement of climate action managers of these cities in multilevel knowledge processes. Using design principles for knowledge systems, it evaluates to what extent knowledge is managed in this field across levels for supporting the energy transition and to what extent local innovation potential is leveraged or supported.
The three case studies show that international research on sustainable energy and municipal climate action in Germany provide promising contributions to achieve a transformation towards sustainability but do not fully reflect the complexity of society and still support a growth paradigm, in contrast to a holistic sustainability paradigm. Further, the case studies show that research and local action are actively engaging with the diversity of energy technologies but are lagging in dealing with the socio-epistemic (communication) system, especially with regard to achieving cohesion. Using the example of German municipalities, Case Studies 1 and 3 highlight the challenges of achieving coherent local action for sustainability and bottom-up organizational learning due to incomplete or uncoordinated multilevel knowledge exchange. At the same time, the studies also point out opportunities for supporting the required coherent multilevel learning processes based on local knowledge. This can be achieved, for instance, by strengthening the coordinating role of intermediary organizational units or establishing closer interactions between the local operational units and the national level.
The thesis interprets and synthesizes the results of the three case studies from its systemic sustainability perspective. On this basis, it provides several generalized recommendations that should be followed for establishing viable communication systems, especially but not exclusively in policy-making:
Systemic holism: Consider matter, energy, and information flows as an integrated triplet in the context of scales, structures, and time in the various subsystems. Knowledge society: Focus on the socio-epistemic (communication) system, e.g., using the perspective of knowledge systems and associated design principles considering, for instance, working environments across horizontal and vertical levels, knowledge forms and types, and knowledge processes. Sufficiency communication: Emphasize sufficiency approaches, make it attractive, and find differentiated ways for communicating them. Multilevel cohesion and innovation: Achieve cohesion between the local and higher levels and leverage local innovations while avoiding isolated local action. Organizational interface design: Define the role of organizational units by the interactions they create at the interfaces with and between societal subsystems. Local transdisciplinarity: Support local transdisciplinary approaches integrating various subsystems, especially industry, while coordinating these approaches from a higher level for leveraging local innovation. Digital public system: Exploit existing digital technologies or infrastructures in the public system and recognize the value of data in the public sphere for achieving cohesion. Beyond the above recommendations, this thesis suggests that potential for further research lies in: Advancing nature-inspired systemic frameworks. Understanding the structure and creation of human knowledge. Developing text mining methodologies towards solution-oriented approaches.
Als Fallstudie wird im ersten Paper der Einsatz der Szenarioanalyse als ein zentrales Element des Forschungsdesigns im Projekt „Sustainable University“ beleuchtet. Mit einem formalen Ansatz wurden Szenarien zum zukünftigen Umfeld der Hochschullandschaft entwickelt. Dieses Paper zeigt detailliert die notwendigen Denkschritte bei der Szenarioentwicklung auf und hilft zu verstehen, an welchen Punkten Integrationsschritte in Bezug auf Wissensarten und Perspektiven unterstützt und geleistet werden und somit auch (soziale) Lernprozesse gefördert werden können. Ferner werden die konkreten Ergebnisse der Szenarioanalyse vorgestellt und diskutiert. Zur Untersuchung von Lerneffekten wird die Methode der Szenarioanalyse in einen formalen Bildungskontext transferiert. Das zweite Paper leistet einen konzeptionellen Beitrag. Einleitend werden spezifische individuelle Kompetenzen diskutiert, die aus der Perspektive der Bildung für eine nachhaltige Entwicklung zum Umgang mit dem Klimawandel als komplexes Nachhaltigkeitsproblem und zu einer aktiven Teilnahme an Transformationsprozessen der Gesellschaft wichtig sind. Die Kompetenzen, wie proaktives Denken, der Umgang mit Unsicherheiten und unterschiedlichen Wissensbeständen sowie das vernetze Denken konnten hier beschrieben werden. Anschließend werden zwei Forschungsmethoden, der Syndromansatz und die Szenarioanalyse, für den Kontext der formalen Bildung nutzbar gemacht, und es wird theoretisch abgeleitet, wie in diesen Lernsettings die eingangs identifizierten Kompetenzen gefördert werden können. Die Szenarioanalyse bietet beispielsweise beim Denkschritt der Entwicklung von Zukunftsprojektionen großes Potential für Reflexionsprozesse oder die Integration von Wissen und Perspektiven zur Förderung der Kompetenz des proaktiven Denkens in Alternativen. Die diskursive Bewertung von Konsistenzen während der Szenarioerstellung birgt ähnliches Potential zur Förderung des vernetzten Denkens. Im dritten Paper wird ein Messinstrument für die Kompetenz des vernetzen Denkens (systems thinking) entwickelt. Es leistet einen empirischen Beitrag zur Lehr-Lernforschung, respektive zur Kompetenzmessung im Bereich der BNE. Dieses Instrument erfasst mit Hilfe eines Similarity Judgment Tests (SJT) den Grad der Vernetzung von Konzepten eines bestimmten Kontextes, in dem konkreten Fall von Aspekten des Klimawandels. In einer prä-post-Studie wurden zwei Kontroll und zwei Versuchsgruppen, die an dem zuvor genannten Lernsetting im Rahmen von Seminaren an der Leuphana Universität Lüneburg teilgenommen haben, empirisch begleitet. Auch wenn keine statistisch signifikanten Veränderungen des vernetzten Denkens der Teilnehmenden nachgewiesen werden konnten, bedeutet das nicht, dass die zuvor abgeleiteten Einflüsse der Szenarioanalyse widerlegt sind. Hier sind weitere Studien und die Weiterentwicklung des Messinstruments nötig. Zudem wurde nur ein Teil möglicher Einflüsse auf die Kompetenzentwicklung untersucht. Für die Szenarioanalyse als Lernsetting lässt sich schlussfolgern, dass zum einen der Moderation von Reflexions- und Diskussionsprozessen während unterschiedlicher Phasen eine sehr wichtige Rolle zukommt und sie einen wesentlichen Einfluss auf Lernprozesse hat. Zum anderen ist den Phasen, in denen Lernen stattfinden kann, genügend Zeit einzuräumen, so dass transdisziplinäre oder interdisziplinäre Forschungsprozesse mit der Methode Szenarioanalyse auch das Potential für Lernprozesse entfalten können. So kann mit Hilfe der Szenarioanalyse ein Setting geschaffen werden, in dem individuelle mentale Modelle und Handlungsmuster hinterfragt und Kompetenzen im Umgang mit komplexen Problemen gefördert werden, und somit individuelles und soziales Lernen für eine nachhaltige Entwicklung stattfinden kann.
To respond to the challenges of the Anthropocene, scholars from various disciplines increasingly emphasize that a mere outer transformation is insufficient and that we also need an inner transformation that addresses deep leverage points. Yet, the open questions are how the inner and outer dimensions relate to each other
and how inner transformation might lead to outer transformation. How we attempt to answer these questions is determined by our dominant paradigm. Paradigms define how we understand and shape the world, and thus, they define how we conceptualize challenges, such as inner and outer transformation. Various authors argue that the dominant paradigm, which is characterized by reductionism, empiricism, dualism, and determinism, might be a root cause for insufficiently addressing sustainability challenges. As an alternative, many argue for a relational paradigm, which understands complex phenomena in terms of constitutive processes and relations. A relational paradigm might offer possibilities to reconceptualize inner and outer transformation in the Anthropocene and might shed new light on how to integrate both in sustainability science. Yet, it is still being determined how a relational paradigm can contribute to the understanding of inner and outer transformations towards sustainability in the Anthropocene. Therefore, this dissertation's overarching scope is to contribute to systems change towards a more social-ecological future by generating insights into and exploring possibilities of a relational paradigm for inner and outer transformation in the Anthropocene. This thesis is divided into three sub-questions. The first research question aims to contribute to transformation research by increasing the theoretical understanding of a relational paradigm. The second research question aims to contribute to transformative research by developing a transformative educational case study grounded in a relational, justice-oriented approach. The third research question aims to contribute to transformation research by analyzing how a relational paradigm might contribute to policies and practices for sustainable lifestyles. The results indicate that inner and outer transformation in the Anthropocene can be reconceptualized as paradigm-ing relationality in the Ecocene. "Paradigm-ing" as an active verb, reconceptualizes inner and outer transformation into ontologies, epistemologies, ethics, and socialecological realities that are ongoing, nonhierarchical, nonlinear, dynamic, co-creative processes of intra-action. The Ecocene decenters the human and attends to what we might be able to intra-actand become-with. These insights can offer unexplored perspectives to address sustainability challenges and increase our capacities to respond in novel ways.
Seit den frühen 1990er Jahren wird transdisziplinäre Nachhaltigkeitsforschung in Form von problemorientierten Forschungs- und Lernprojekten konzeptioniert und praktisch umgesetzt, an denen außeruniversitäre Akteur_innen beteiligt sind. Diese Forschungsarbeit verfolgt drei Ziele: Erstens, die Konzeptualisierung der Begriffe Kultur, Multi-, Inter- und Transkulturalität in der Literatur zur transdisziplinären Nachhaltigkeitsforschung zu untersuchen. Zweitens, die Konzeptionierung und Umsetzung von transdisziplinären Forschungs- und Lernprojekten in Hinblick auf kulturelles Differenzieren zu analysieren. Drittens, konzeptionelle Beiträge zur Gestaltung von transdisziplinären Forschungs- und Lernprojekten zu entwickeln. Methodisch wird auf Literaturanalysen und eine qualitative Untersuchung zweier transdisziplinärer Lernforschungsprojekte zurückgegriffen. Unter dem Begriff Forschungs- und Lernprojekt werden in dieser Forschungsarbeit sowohl Forschungsprojekte als auch Lehr-Lernforschungsprojekte gefasst. Zentrale Ergebnisse der Forschungsarbeit sind die Folgenden: Erstens wird der Kulturbegriff in der transdisziplinären Nachhaltigkeitsforschung zwar vielfältig verwendet, als Forschungsthema, Hintergrund von Beteiligten, Kooperationsweise, Projektkontext, in Hinblick auf Interkulturalität oder als Wissenskultur, allerdings kaum ausdifferenziert und konkretisiert. Zweitens besteht auf der Ebene der Konzeptionierung von transdisziplinären Forschungs- und Lernprojekten: 1) ein starkes Übergewicht von Integration und Konsens gegenüber einer Auseinandersetzung mit Differenz, 2) eine implizite Vorauswahl von Beteiligten durch bestimmte Begrifflichkeiten und methodologische Ansätze und 3) eine Reproduktion von Machtverhältnissen durch (dichotome) Symmetrie- und Ausgleichsvorstellungen. Drittens zeigt sich auf der Ebene der Umsetzung von Lernforschungsprojekten: 1) eine starke Prozessorientierung der Projekte, 2) ein Spannungsfeld zwischen einer Öffnung und Steuerung in Hinblick auf den Projektverlauf und 3) vielfältige Differenzaushandlungen in Interaktionen (wie Zeitlichkeit, Verantwortung, Erfahrung, Relevanz). Die Ergebnisse zeigen, dass politische Implikationen der Forschung und zentrale Ungleichheitskategorien der Kultur- und Sozialwissenschaften (u.a. race, class, gender, body) kaum thematisiert werden. Vorschläge zur Gestaltung transdisziplinärer Forschungs- und Lernprojekte werden in Hinblick auf ein Verständnis von Forschungsdesigns als Prozesse, einem Erkunden von Differenzierungen und Forscher_innen-Positionen und der Bedeutung eines Verlernens entwickelt. Die folgenden Vorschläge zur Gestaltung von transdisziplinären Forschungs- und Lernprojekten werden aus den Ergebnissen entwickelt: Kulturkonzepte sollten nicht als voneinander getrennt, sondern als miteinander verschränkt betrachtet werden. Generell sollten Kulturkonzepte stärker definiert werden. So können durch offene Kulturkonzepte problematische Implikationen (Stereotypen, Rassismus, Kulturalisierung) vorgebeugt werden, die Zielen transdisziplinärer Forschung entgegenstehen. In Hinblick auf die Arten und Weisen kulturellen Differenzierens sollte bewusster mit Differenzierungen umgegangen werden (Wer differenziert wen wie?). Dies schließt ein, eine Sensibilität gegenüber kulturellem Differenzieren zu entwickeln und Differenzierungen in Forschungsprozessen zu erkunden. Kulturelles Differenzieren entfaltet ein wichtiges epistemologisches und transformatives Potential in der transdisziplinären Forschung, um Selbstverständlichkeiten zu reflektieren und Gemeinsamkeiten zu entdecken.
The image of the solitary scientist is receding. Increasingly, researchers are expected to work in collaborative interdisciplinary teams to tackle more complex and interrelated problems. However, the prospect of collaborating with others, from different disciplines, exerts countervailing forces on researchers. There is the lure of transcending the limitations of one’s own knowledge, methods and conventions, belonging to diverse intellectual communities and tackling, together, ambitious research topics. On the other hand, there is the risk that collaborating across disciplinary boundaries will be taxing, confounding at times, with no guarantee of success. In short, interdisciplinary collaboration is both a desirable and difficult way to conduct research. This thesis is about collaborative interdisciplinary research from the perspective of a formative accompanying researcher. I accompanied an interdisciplinary research team in the field of sustainability over three years for the duration of a collaborative project. Formative accompanying research (FAR) is an approach to ‘research into research’ that learns about, with and for a collaborative interdisciplinary team. I found – through immersion in the literature, my own daily experiences of collaborating, and my observations – that interdisciplinary collaboration is very difficult. It requires a basic understanding and appreciation of other disciplines and methods, as well as the skills to integrate research inquiries and findings across diverse epistemologies. It also requires awareness that collaborative interdisciplinary research is more than an intellectual task of knowledge creation. Other factors matter, such as interpersonal relationships, power differentials, different research tempos and a sense of belonging. And these factors have an impact on processes and outcomes of collaborative knowledge creation. Knowing this implies a willingness to keep learning and to tolerate discomfort so as to cultivate deeper levels of collaborative capacity. I discovered that in these deeper levels lie skills for staying with inevitable tensions, for talking and listening to generate new understanding together, and for applying a researcher’s frank curiosity to oneself too. A formative accompanying researcher, who is part of the team she is researching, has to navigate delicate terrain. In this thesis, I develop a FAR methodology that takes seriously the questions of positionality and relationality, and reflect on the experiences of putting these into practice. A FAR practice involves remaining in dynamic movement between observing and participating, between exercising curiosity and care, and between the researchers’ own sense of impartiality and investment in relation to the issues at hand. There is merit in furthering the methodology and practice of FAR on its own terms. This includes attending to the skills required by a formative accompanying researcher to remain oriented within the concentric circles of research, relationship and loyalty that make up a collaborative team. There is also the question of how FAR, and other forms of research into research, can help to advance collaborative interdisciplinary research. I argue for creating the conditions in research teams that would enable treating collaboration as a capacity to develop, and that would facilitate team members’ receptivity to learning with FAR. Furthermore, I explore dilemmas of intervening as a formative accompanying researcher and of sustaining dynamic positionality over the long-term. In the field of sustainability research, and in multiple other research fields, the future is a collaborative one. This thesis is concerned with how to collaborate so that the experience and the outcomes lend themselves to what Rabinow terms a “flourishing existence”.
Given the complex, dynamic, and urgent problems that sustainability science addresses, research approaches are required that not only improve the understanding of sustainability challenges, but also to support action for sustainable development. In this context, transdisciplinary research has established as an approach that aims not only to generate new knowledge, but also to promote the societal relevance and application of research findings through direct collaboration of scientists and societal stakeholders from different fields in integrative research processes. Despite its increasing prevalence in the field, there remains a gap between theoretical ideal-typical models of transdisciplinary research and its actual application within sustainability science. While scholars generally agree that transdisciplinary research is societally effective, there is scattered and partly conflicting evidence on which aspects of transdisciplinary research foster societal impact. Moreover, the extent to which transdisciplinary research contributes to scientific progress is largely unexplored.
This thesis aims to contribute to a better understanding of the actual implementation of transdisciplinary research in sustainability science. Following three aims, this work likes to (1.) contribute to the measurability of transdisciplinary research processes as well as their societal and academic outputs and impacts, to (2.) demarcate transdisciplinary research from other modes of research in sustainability science and to (3.) identify and examine the determinants that shape the contribution of transdisciplinary research to societal action for sustainable development and to scientific knowledge production.
To serve these aims a mixed methods approach is applied that combines strong quantitative elements with in-depth qualitative analyses that integrate the perspectives of practitioners. This thesis provides a broad set of indicators to describe and assess transdisciplinary research that translate theoretical concepts form transdisciplinarity theory into observable variables. The indicators offer a holistic perspective on transdisciplinary research by representing research mode characteristics, societal as well as scientific outcomes of research projects and their specific context.
To theoretically demarcate transdisciplinary research from other forms of research, a narrative literature review first elaborates the differences between ‘normal science’, political use of scientific knowledge and transdisciplinarity in their underlying logics of problem definition, knowledge production and research utilization. Subsequently, these concepts were compared with perspectives and expectations of practitioners in the forest sector on integrative research settings, showing that practitioner perspectives align the most with conceptualizations of political use of scientific knowledge.
Moreover, a cluster analysis of data from 59 research projects identified five research modes that empirically demarcate ideal-typical transdisciplinary research from other research modes within sustainability science: (1) purely academic research, (2.) practice consultation, (3.) selective practitioner involvement, (4.) ideal-typical transdisciplinary research and (5.) practice-oriented research. Based on this finding, transdisciplinary research can be characterized as an intensive, but balanced involvement of practitioners. It incorporates not only the needs and goals of the practitioners but also their norms and values. Ideal-typical transdisciplinary research goes beyond mere consultatory research approaches and must be distinguished from what is conceptualized as applied research.
Regression analysis of 81 research projects and statistical group comparisons of the five research mode clusters show that societal and academic outputs and impacts vary with specific project characteristics and combinations of project characteristics defined as research modes. The findings indicate that more interactive research modes reach more societal impacts. In particular, the involvement of practitioners in early project phases and the targeted dissemination of the research results positively affect societal impacts. This finding also aligns with practitioner expectations on integrative research and research utilization, provided by qualitative analysis. Moreover, the quantitative results show that scientific outputs and impacts decrease with the intensity of interactions, indicating a trade-off between societal and scientific outcomes and impacts.
Overall, the empirical results of this thesis support the claimed effectiveness of transdisciplinary research in providing societally relevant, applicable knowledge and encourage further funding of transdisciplinary research by funding agencies. The relationships discovered in this study between research mode characteristics and societal as well as academic outputs and impacts can help researchers design and reflect on their research and can inform funding agencies in the design of project calls and research programs. However, the observed lower academic outputs and impacts of more integrative research modes raise the question of how to further strengthen the systematic documentation and accessibility of the results of transdisciplinary sustainability research. Additionally, the observed trade-off between societal and academic impacts of transdisciplinary research highlights the need for strategies to mediate between the dual aim of transdisciplinary research to contribute to societal problem solving and scientific knowledge production.

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).
