Der Rückgang der Wildtiere kann Ökosysteme tiefgreifend verändern und das Risiko von Ernährungsunsicherheit und neu auftretenden Krankheiten erhöhen, die wiederum die globale Gesundheit, Gesellschaft und Wirtschaft bedrohen. Aufbauend auf dem theoretischen Überbau des Konzepts komplexer sozial-ökologischer Systeme untersuche ich in dieser Dissertation die Jagd und den Wildtierhandel in einem ganzheitlichen, differenzierten und skalensensitiven Ansatz. Dabei untersuche ich die Ursachen der Wildtiernutzung auf verschiedenen Ebenen (z.B. Nutzergruppen) und Skalen (lokal, global). Ich untersuchte ein lokales Umfeld durch eine Fallstudie um den Taï-Nationalpark in der Elfenbeinküste, indem ich 348 Jäger, 202 Buschfleischhändler, 190 Restaurantbesitzer und 985 Verbraucher in 47 städtischen und ländlichen Siedlungen befragte. Darüber hinaus untersuchte ich mithilfe von 114 persönlichen Interviews mit Nationalparkdirektoren in 25 afrikanischen und europäischen Ländern die Ausprägung der Jagd über den sozioökonomisch und ökologisch kontrastreichen globalen Süd-Nord-Gradienten. Die lokale Fallstudie zeigte die Heterogenität der Wildfleisch-Warenkette, in der mehrere Akteure Wildfleisch und verschiedene Taxa aus unterschiedlichen wirtschaftlichen, kulturellen oder ernährungsbedingten Beweggründen nutzen. Die globale Perspektive zeigte die sich verändernden Erscheinungsformen und Gründe für die Jagd entlang des globalen Süd-Nord-Gradienten. Im Süden überwog die illegale und kommerzielle Jagd auf Pflanzenfresser, während im Norden die legale, kulturell und sozial motivierte Jagd auf Huftiere und die illegale Jagd auf Raubtiere außerhalb von Parkgrenzen dominierte. Die Einbindung lokaler Gemeinschaften und die Berücksichtigung universeller Mechanismen menschlicher Kooperation könnte dem Naturschutz und der sozialen Gerechtigkeit zugutekommen. Nichtsdestotrotz verdeutlichen die Auswirkungen großräumiger Faktoren auf lokale Systeme die Notwendigkeit, gut umgesetzte lokale Maßnahmen mit einer angemessenen globalen Governance zu kombinieren, um den Raubbau an der Natur einzudämmen. / Declining wildlife can profoundly alter ecosystems and increase the risks of food insecurity and emerging diseases that threaten global health, societies, and economies. Building on the theoretical superstructure of complex social-ecological systems, I examine wildlife trade in a holistic, differentiated, and scale-sensitive approach, exploring the causes of wildlife use at different levels (e.g. user groups) and scales (local, global). I examined a local setting through a case study around Taï National Park in Côte d'Ivoire by interviewing 348 hunters, 202 bushmeat traders, 190 restaurant owners, and 985 consumers in 47 urban and rural settlements. Furthermore, I investigated the manifestation of hunting across the Global South-North gradient through 114 face-to-face interviews with national park directors in 25 African and European countries. The local case study revealed the heterogeneity of the wild meat commodity chain, in which multiple actors use wild meat and different taxa for varying economic, cultural, or nutritional motivations. The global perspective revealed the shifting manifestations and reasons for hunting along the Global South-North gradient. Illegal, commercial hunting of herbivores prevailed in the South, while legal, culturally-, and socially-motivated hunting of ungulates and the illegal pursuit of predators outside park boundaries were common in the North. Engaging local communities and incorporating universal mechanisms of human cooperation into conservation could benefit conservation and social justice. The impacts of large-scale drivers on local systems highlight the need for combining well-implemented local action and appropriate global governance to curb wildlife overexploitation

In this study, we examined the extent to which global warming management is currently integrated into the European Water Framework Directive (WFD), the central legal framework for water management in the EU. We focused on the Elbe River Basin District and how global warming is addressed in its water management. We used the social–ecological systems (SES) approach as our theoretical framework, representing an eminent analytical frame of biosphere-based sustainability science. In our study, we analysed core characteristics of SES in the context of global warming to evaluate the effectiveness of current water management in the Elbe River basin concerning long-term changing climate conditions. To determine to what extent each SES feature is considered in the Elbe water management, we applied a scale of 1 to 5. Our results show that the SES feature “scale and openness” is best addressed (score 4.0) by the Elbe River basin management, followed by “context dependency” (score 3.9); however, “non-linearity, uncertainty, unpredictability” (score 3.2), “self-organisation and adaptability” (score 3.1), and “dynamics” (score 3.0) have only moderate impacts. SES features can only be considered comprehensively if global warming is accounted for in an integrated way at a European level. In order to ensure effective implementation, explicit regulations and legally binding obligations are most likely required.

La gouvernance pour le développement durable comporte de nombreux défis. L'un de ces défis consiste à mieux comprendre les systèmes socio-écologiques gouvernés. Dans de tels systèmes, l'apprentissage par essais et erreurs implique le risque de conséquences inattendues, irréversibles et néfastes. De plus, en raison de la complexité des systèmes socio-écologiques, les leçons tirées d'expériences à petite échelle ne peuvent pas toujours être applicables à des problèmes à grande échelle. Un autre aspect difficile des problèmes de développement durable est que ces problèmes sont souvent multidisciplinaires et composés de composants qui sont chacun étudiés individuellement dans une discipline différente, mais il existe peu d'informations sur leur comportement ensemble. Un troisième défi de la gouvernance pour le développement durable est qu'il est souvent nécessaire d'impliquer les parties prenantes dans des actions de gestion et des mesures d'intervention coûteuses pour les individus qui y participent. De plus, dans de nombreuses situations de ce type, les incitations financières et l'application des réglementations se soldent par un échec et ne constituent donc pas des options de gouvernance. Dans cette thèse, les défis ci-dessus sont abordés dans un exemple de contrôle des perturbations forestières avec une approche intégrée. Pour éviter le problème des effets indésirables irréversibles et pour permettre des expériences répétées, une approche de simulation est utilisée. Pour relever le défi de la multidisciplinarité des problèmes des systèmes socio-écologiques, deux modèles sont développés indépendamment - portant sur les aspects sociaux et écologiques du système de l'étude - et ils sont ensuite couplés de telle sorte que la sortie de chaque modèle est utilisée comme entrée pour l'autre modèle. Pour résoudre le problème de l'engagement des parties prenantes, un plan est proposé pour la promotion d'un comportement respectueux de l'environnement. Ce plan est basé sur l'offre de reconnaissance à ceux qui adoptent volontairement le comportement responsable. Le modèle écologique de cette étude, qui simule la propagation d'une perturbation forestière, est construit à l'aide de l’apprentissage automatique supervisé. Le modèle social de cette étude, qui simule l'émergence d'une nouvelle norme de comportement, est construit à l'aide de l'apprentissage par renforcement. Les deux modèles sont testés et validés avant couplage. Le modèle couplé est ensuite utilisé comme un laboratoire virtuel, où plusieurs expériences sont réalisées dans un cadre hypothétique et selon différents scénarios. Chacune de ces expériences est une simulation. A travers ces simulations, cette étude montre qu'avec un algorithme de prise de décision approprié et avec suffisamment de temps pour l'interaction entre une entité gouvernante et la société, il est possible de créer une motivation pour un comportement responsable dans la société. En d'autres termes, il est possible d'encourager la participation volontaire des acteurs à l'action pour le développement durable, sans que l'entité gouvernante ait besoin d'utiliser des incitations financières ou d'imposer son autorité. Ces résultats peuvent être applicables à d'autres contextes où un comportement responsable des individus ou des entreprises est recherché afin d'atténuer l'impact d'une perturbation, de protéger une ressource écologique, ou de faciliter une transition sectorielle vers la durabilité. / Governance for sustainable development involves many challenges. One of those challenges is to gain insight about the social-ecological systems being governned. In such systems, learning by trial and error involve the risk of unexpected, irreversible and adverse consequences. Moreover, due to complexity of social-ecological systems, lessons learned from small scale experiments may not be applicable in large-scale problems. Another challenging aspect of problems of sustainable development is that these problems are often multidisciplinary and comprised of components that are each studied individually in a different discipline, but little information exists about their behavior together as a whole. A third challenge in governance for sustainable development is that often it is necessary to involve stakeholders in management actions and intervention measures that are costly for individuals who participate in them. Moreover, in many of these situations financial incentives or enforcement of regulations result in failure, and are thus not options for governance. In this thesis, the above challenges are addressed in an example case of forest disturbance control with an integrated approach. To avoid the problem of irreversible adverse effects and to allow repeated experiments, a simulation approach is used. To tackle the challenge of multidisciplinarity of problems of social-ecological systems, two models are independently developed – pertaining to social and ecological aspects of the system of the study – and they are subsequently coupled in such a way that the output of each model served as an input for the other. To address the problem of engagement of stakeholders, a scheme is proposed for promotion of environmentally responsible behavior. This scheme is based on offering recognition to those who voluntarily perform the responsible behavior. The ecological model of this study, which simulates the spread of a forest disturbance, is built using Supervised Machine Learning. The social model of this study, which simulates the emergence of a new norm of behavior, is built using Reinforcement Learning. Both models are tested and validated before coupling. The coupled model is then used as a virtual laboratory, where several experiments are performed in a hypothetical setting and under various scenarios. Each such experiment is a simulation. Through these simulations, this study shows that with an appropriate decision-making algorithm and with sufficient time for interaction between a governing entity and the society, it is possible to create motivation for responsible behavior in the society. In other words, it is possible to encourage voluntary participation of stakeholders in action for sustainable development, without the need for the governing entity to use financial incentives or impose its authority. These results may be applicable to other contexts where responsible behavior by individuals or enterprises is sought in order to mitigate the impact of a disturbance, protect an ecological resource, or facilitate a sectoral transition towards sustainability.

Temporary closures of octopus fishing areas constitute a promising co-management measure that aims to improve local governance, food security and incomes in coastal small-scale fishing communities. Although positive social and economic outcomes of temporary closures are increasingly reported, the underlying social-ecological and ecological interactions, and their impact on closure benefits are rarely studied. This lack of systemic understanding may lead to undesired outcomes. Here, I extend an existing agent-based model of temporary closures to explore the influence of individual octopus movements on ecological outcomes and fishers’ benefits in Zanzibar. First, I conceptualized the octopus closure system by analyzing empirical qualitative data and literature. Next, I iteratively developed and tested an individual-based model extension. This extension simulates between-den movements across a hypothetical seascape and formalizes intrinsic attributes of Octopus cyanea such as movement patterns and maturity stages. I analyzed the effects of varying closure size of fishing grounds temporarily closed to illustrate potential implications for outcomes of octopus closures. Simulation results show that individual octopus movements triggered by fishing activities have noticeable impacts on octopus sizes, their spatial and temporal distribution, and fishers’ catches, particularly when considering different social groups that depend on the fishery. Scenarios with closures in place show higher mean octopus weight in closed areas in contrast to open-access areas. Mean catches for women foot-fishers are lower compared to freedivers’ catches and even slightly lower when allowing octopuses to move in response to disturbance in all scenarios. Catch rates and distribution of mature octopuses are highly sensitive to closure size revealing a social-ecological trade-off when implementing larger closures. This study demonstrates an approach to integrating individual octopus movements and interactions between fishers and octopuses in a fishery management context, and suggests that reactive movement of octopus contributes to unequal distribution of the closure benefits between different social groups. / Octopus and People In Novel Transdisciplinary Simulations (OctoPINTS project)

The Rights of Nature is a relatively new approach to sustainable development, promoting that current environmental legislation is insufficient to protect Nature from human harm. The Rights of Nature movements emphases the importance of recognizing other living entities in our legal system. Ecuador was the first country in the world to incorporate the Rights of Nature into its Constitution in 2008. Based on semi-structured interviews, this study aims to investigate the awareness of the Rights of Nature among the inhabitants of the Equatorian small-town of Esperie and how they perceive and relate to the Rights of Nature in practice and whether the implementation has brought about any changes in their lives and community. The central findings of the study demonstrate that the majority of the respondents are aware of the Rights of Nature, also led to changes in society but also in respondents' lives and environment. The results also revealed various challenges that have arisen in the implementation of the Rights of Nature in practice and Due to stricter environmental laws and pressure from the people, the authorities have started to take measures to protect and respect Nature.

Angesichts der weltweit zunehmenden Zerstörung von Ökosystemen spielen ökologisch wirksame und sozial gerechte Umweltschutzinstrumente eine wichtige Rolle. Zahlungen für Ökosystemleistungen (Payments for Ecosystem Services, PES) finden zunehmend Anwendung. Sie dienen als freiwillige und konditionale Anreize für die Bereitstellung von Ökosystemleistungen. Einige dieser PES-Verträge werden mit lokalen Gemeinschaften abgeschlossen, die die Vertragsbedingungen gemeinsam erfüllen (Collective PES, C-PES). Während diese Programme einerseits als Chance für einen erfolgreichen Umweltschutz gesehen werden, wird zum anderen befürchtet, dass sich die Einführung von Marktprinzipien negativ auf lokale Gemeinschaften auswirkt. Vor diesem Hintergrund widmet sich die Dissertation der Frage, inwieweit C-PES-Programme die sozial-ökologische Transformation in Richtung Nachhaltigkeit fördern oder erschweren. Paper I gibt einen literaturgestützten Überblick über Definitionen und Systematisierungen von Kommodifizierungsprozessen und deren sozial-ökologische Auswirkungen. Basierend auf einem im ersten Paper entwickelten Framework werden in Paper II 29 C-PES-Programme weltweit hinsichtlich ihres ökosystemleistungsbezogenen Kommodifizierungsgrades untersucht. Paper III fokussiert auf Mensch-Wildtier-Konflikte im Zusammenhang mit einem Schutzprogramm für Vielfraße und Luchse im Kontext indigener Samen-Gemeinschaften in Schweden. Insgesamt zeigt sich, dass C-PES nicht per se eine Transformation in Richtung sozial-ökologischer Nachhaltigkeit unterstützen, sondern nur dann einen erfolgreichen Beitrag leisten können, wenn bei der Umsetzung die lokalen Gegebenheiten berücksichtigt und Entscheidungen über die Programmgestaltung inklusiv getroffen werden. Darüber hinaus ist es wichtig, dass C-PES Programme engere Mensch-Natur-Beziehungen ermöglichen und in einen umfassenden institutionellen Wandel eingebettet sind, der sich über verschiedene räumliche und politische Ebenen erstreckt. / As ecosystems around the world continue to degrade, the implementation of ecologically effective and socially just conservation instruments is critical. Payments for ecosystem services (PES) are an increasingly popular tool. PES are voluntary and conditional incentives for the provision of ecosystem services, rewarding landowners for their conservation efforts. Some PES programs target local communities that collectively meet contractual obligations (collective PES, C-PES). Proponents see C-PES as a promising tool for successful nature conservation, while critics argue that the introduction of market principles into areas not previously characterized by them can have negative effects, such as the erosion and replacement of well-functioning local community institutions and the crowding out of intrinsic conservation motivations. Against the background of these controversies, this dissertation aims to contribute to answering the question of how paying local communities for their conservation efforts supports or hinders the social-ecological transformation towards sustainability. Paper I reviews definitions and systematizations of program-related commodification processes and local land tenure structures, and their links to social-ecological program outcomes. Based on a framework developed in the first paper, Paper II examines 29 C-PES programs worldwide regarding their ES-related degree of commodification. Paper III focuses on human-environment conflicts in the context of conservation performance payments for wolverines and lynxes in Sweden, which are made to indigenous Sámi communities. Overall, the findings of the three papers suggest that C-PES programs do not in themselves address leverage points for a sustainability transformation, but can only be fully effective when implemented in a careful and inclusive manner, ensuring that they contribute to a larger institutional change across scales and when they support closer connections between people and nature.

Amsterdam and Dhaka are two cities that represent the global north and the global south respectively. Both cities are, because of climate change, prone to heavy rain that can lead to flooding. Due to the fact that global north and global south are facing different challenges when it comes to implementing urban resilience, in combination with lack understanding of how policy of urban resilience is created, it leads to question if the global north and global south differ regarding their understanding of urban resilience. The purpose of this study was therefore to compare narratives of urban resilience in Amsterdam and Dhaka to explore if the understanding of urban resilience in various documents differ between the global north and global south. Therefore, the study aimed to provide an understanding of whether who describes urban resilience is important for how urban resilience is presented. This study applied socio-ecological theory to explain whether the strategies implemented can be characterized as transformative or adaptive approach to urban resilience. Further, the study was conducted using qualitative narrative analysis. Finally, this study shows that narrative of urban resilience differs between Amsterdam and Dhaka, which indicates that the narrator has an impact on the presentation of urban resilience. The study also shows that narrative of urban resilience has an impact on which strategies are employed. Finally, power also plays an important role in crisis management.

Plastics pollution is a global planetary threat to both humans and the environment, leading to injustice throughout its lifecycle and disproportionately affecting the most vulnerable. The United Nations Environmental Assembly adopted Resolution 5/14 to create a legally binding instrument to end plastics pollution, known colloquially as the Plastics Treaty. The treaty is currently under negotiation, and the implicit understandings of justice that will be incorporated will significantly impact the outcome of the treaty. This thesis employs critical discourse analysis and key stakeholder interviews to examine the various justice narratives and framings of actors in the treaty through an environmental justice lens. Additionally, the role of power in shaping these narratives is examined from a critical and decolonial perspective. My research demonstrates the value of a critical approach in addressing power dynamics and normative concepts such as justice in social-ecological and sustainability research. This study identifies three distinct discourses, each offering different problematizations of plastics and justice framings. The analysis reveals competing definitions of just transition, a disconnect between the recognition of Indigenous Knowledge and the rights of Indigenous People, and underdeveloped gender and intersectional considerations. Furthermore, this thesis highlights the enduring influence of colonial dynamics on plastics pollution, potentially reinforcing waste colonial relations in the Plastics Treaty. Finally, this thesis contends that problematizing plastics as a human rights issue offers a valuable approach to address these shortcomings, thereby enhancing the treaty's potential for promoting justice by ensuring that the voices of those most affected are heard.

While adaptation to climate change is important, resilience thinking is the next step toward development of the adaptive capacity and transformability of structures in society in the face of ongoing climate related problems. Municipalities in Sweden have been struggling with adaptation in various degrees since this term has been used in practice since 2010. But there is more happening underneath the formal structures than we can imagine. Surprising developments have been detected through this project which was aimed at following up how municipalities are working with climate adaptation and resilience. Even though climate adaptation per se, is not implemented as such, as a program, plan or strategy. The internal bottom-up actions taken through terrific communication between departments, and through ambitious and well-educated staff and above that, informal transdisciplinary coordination of information. Are all components which indeed go above and beyond the term of climate adaptation. Thus, moving into the spheres of resilience thinking in social-ecological systems.

Spinal cord injury (SCI) is an acquired physical disability through traumatic injuries such as car accidents and shooting incidents, and non-traumatic injury such as a tumour on the spinal cord, amongst others. Unlike other parts of the body, the spinal cord does not have the ability to repair itself if it is damaged. Consequently, a person who has acquired an SCI will have a physical disability and will be either a paraplegic – paralysis of the lower part of the body, including the legs, or a quadriplegic, which is paralysis of all four limbs. Acquiring a spinal cord injury (SCI) has devastating long-term negative outcomes for the injured person as well as his/her cohabiting partner on a physical, psychological, psychosocial and socio-economical level. Exposure to such prolonged adversity and resulting negative outcomes calls for resilience, namely the ability to positively adapt despite the adversity being exposed to. Not all individuals have the natural ability to “bounce back”, and consequently resilience promotion is imperative. In South Africa, the focus of service delivery in rehabilitation centres is mainly centred on the injured person and consequently the well-being of the spinal cord injured person’s partner (SCIPP) is neglected. Little information is available on resilience-promoting programmes for SCIPPs; thus the main aim of this study was to design and develop a group resilience-promoting programme (GRPP) for SCIPPs. The researcher mainly followed a qualitative research approach and included a small quantitative component. In the context of applied research, an intervention research model comprising six phases was employed. Phase 1, Problem analysis and project planning, was reported on in section A. Manuscript 1 reports on phase 2 (information gathering and synthesis), and consists of a qualitative research synthesis, and mainly aimed at organizing and synthesizing previous research on resilience-promoting processes in order to inform the design and development of a group resilience-promoting programme (GRPP) for SCIPPs. After a systematic review and quality appraisal a total of 74 papers were selected to be quality appraised after abstracts and titles were assessed for relevance. Twenty-one studies were included and synthesized where after an outline for the content of a GRPP for SCIPPs was formulated. Conclusions and recommendations highlight that the formulated GRPP for SCIPPs needs to be further developed into an intervention that could be implemented with SCIPPs. As such, the researcher therefore proceeded with the study (see manuscript 2), aiming in developing small-group programme content and activities (using knowledge gathered from pre-existing interventions; resilience literature; consultations with experts; people living with spinal cord injury (SCI) and personal experience) to promote resilience in SCIPPs. By means of purposive sampling six advisory panel members from a diverse background were interviewed before and after the pilot study with two SCIPPs and one observer to contribute towards the further development of the GRPP for SCIPPs. A six-session GRPP for SCIPPs was formulated, including the following: (1) Information on SCI and resilience; (2) Help SCIPPs understand that their reactions to/emotions regarding these huge changes are normal; (3) Caretaking and support; (4) My dual role; (5) Own caretaking by SCIPPs; and (6) Termination and way forward. The newly developed GRPP for SCIPPs however had to be formally evaluated. Recommendations were made by professionals in the field that the GRPP for SCIPPs should first be subjected to peer review prior to implementing it with the target population. Therefore in manuscript 3 (reporting on phase 5 – evaluation ) the evaluation purpose was to subject the GRPP for SCIPPs to peer review by means of an empirical study with professional role-players (social workers and psychologists) in the field of spinal cord injury, prior to exhibiting it to the target population. The six group sessions were presented to professional role-players (n=12) working within the field of SCI during two 2-day workshops, whereby they were requested to evaluate the content and procedural elements of the GRPP for SCIPPs mainly by means of qualitative research, with a small numerical (quantitative) component. Thematic content analysis and basic descriptive statistics were employed. Overall positive feedback regarding the newly developed intervention was received, with suggested adjustments that needed to be made to the GRPP for SCIPPs prior to formal evaluation with the target group. The GRPP for SCIPPs will further be subjected to expert review in other provinces in South Africa, as the current participants were all from Gauteng. Furthermore, postgraduate students will be recruited to test the programme with the target-population in South Africa for possible further improvement and suggestions, as well as possible expansion to adjust this intervention to meet the needs of male SCIPPs; SCIPs themselves; children of a parent/s living with SCI; and also for post-injury cohabiting relationships, as this intervention might be a starting point for above-mentioned research-opportunities.
