Im Rahmen einer Masterarbeit untersuchten wir mögliche Herausforderungen partizipativer Prozesse. Hierzu führten wir Interviews mit Expertinnen und Experten aus der Praxis und der Wissenschaft. Durch die Analyse der Interviews identifizierten wir zehn Herausforderungen, die sich wie folgt in den drei Phasen eines partizipativen Prozesses verorten lassen: 1) Anwerben von Partizipierenden, die Unterschiede zwischen Wissenschaft und Praxis, Transparenz und die Konnotationen des Wortes «Partizipation»; 2) Partizipationskompetenzen, Gruppendynamik und Vertrauen; 3) Zeitmangel, gemeinsame Sprache und fehlende finanzielle Mittel. Zudem haben wir für diese zehn Herausforderungen in der Literatur Lösungsansätze identifiziert.

ABSTRACT Modern industrial agriculture is predicated largely on the production and utilization of chemical fertilizers. Although this approach has played an integral role in increasing food security in many parts of the world, the long‐term sustainability of this resource‐intensive approach is questionable. Efforts to quantify the sustainability implications of various fertilizer sources typically focus on individual elements within the larger issue of sustainability. We argue that a more comprehensive framework, one that accounts for the biophysical, socio‐economic, and political implications of fertilizer production and consumption, is necessary to direct agricultural production towards a more environmentally sustainable and socially equitable trajectory. By incorporating criteria associated with equitable access, environmental production impacts, closed loop fulfilment, and agroecosystem performance into a single framework, we hope to stimulate renewed discussion regarding how to comprehensively assess sustainable fertilizer production and use.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries. The data were collected between November 2022 and August 2023 as part of the global Many Labs study “Trust in Science and Science-Related Populism” (TISP). The questionnaire contained comprehensive measures for individuals’ trust in scientists, science-related populist attitudes, perceptions of the role of science in society, science media use and communication behaviour, attitudes to climate change and support for environmental policies, personality traits, political and religious views and demographic characteristics. Here, we describe the dataset, survey materials and psychometric properties of key variables. We encourage researchers to use this unique dataset for global comparative analyses on public perceptions of science and its role in society and policy-making.

The coffee value chain (VC) faces several social-ecological challenges. Material resources and value creation are unequally distributed with a higher concentration at the end of the VC, mostly among multinational companies located in the global North. Companies and organizations of the global North dominate discourses and design and apply sustainability initiatives in origin countries, raising questions of legitimacy and impact. For sustainability initiatives to be successful, it may be necessary to involve different actors of the VC in decision-making processes and to better understand their views, needs, and priorities. In this study, we included different standpoints represented in 10 case studies of different coffee VCs to explore what matters for different actors in Brazil, the Democratic Republic of Congo (DRC), and Switzerland. We adopted a mixed methods approach and conducted (1) focus group discussions with rural workers, metayers, (a type of sharecropper), farmers, and management/office staff of cooperatives and plantations in Brazil and DRC, (2) interviews with plantation owners and cooperative/company managers in Brazil and DRC, and (3) online surveys with roasters and consumers in Brazil, DRC, and Switzerland. We found a strong mismatch of the different perceptions of the different actors. Farmers strive for a dignified quality of life, plantation owners and cooperative/company managers for better economic conditions, rural workers for better working conditions, roasters for a great drinking experience, and consumers for pleasure and a hedonistic lifestyle. Our findings underline the importance of including diverse standpoints in coffee sustainability efforts, particularly those of rural workers and smallholders.

This 68-country survey (n = 71,922) examines science information diets and communication behavior, identifies cross-country differences, and tests how such differences are associated with sociopolitical and economic conditions. We find that social media are the most used sources of science information in most countries, except those with democratic-corporatist media systems where news media tend to be used more widely. People in collectivist societies are less outspoken about science in daily life, whereas lower education is associated with higher outspokenness. Limited access to digital media is correlated with participation in public protests on science matters. We discuss implications for future research, policy, and practice.

Science is crucial for evidence-based decision-making. Public trust in scientists can help decision makers act on the basis of the best available evidence, especially during crises. However, in recent years the epistemic authority of science has been challenged, causing concerns about low public trust in scientists. We interrogated these concerns with a preregistered 68-country survey of 71,922 respondents and found that in most countries, most people trust scientists and agree that scientists should engage more in society and policymaking. We found variations between and within countries, which we explain with individual- and country-level variables, including political orientation. While there is no widespread lack of trust in scientists, we cannot discount the concern that lack of trust in scientists by even a small minority may affect considerations of scientific evidence in policymaking. These findings have implications for scientists and policymakers seeking to maintain and increase trust in scientists.

Extreme weather events have severe impacts on food systems, especially for smallholders in global food value chains (GFVCs). There is an urgent need to understand (a) how climate shocks manifest in food systems, and (b) what strategies can enhance food system resilience. Integrating satellite, household and trade data, we investigate the cascading impacts after two consecutive hurricanes on smallholder banana farmers in Dominican Republic, and determinants of their recovery. We found that farmers experienced an ‘all-or-nothing’ pattern of damage, where 75% of flooded farmers lost > 90% of production. Recovery of regional production indicators took ca. 450 days. However, farm-level recovery times were highly variable, with both topographic and human capital factors determining recovery. Utilising this case study, we show that engaging in a GFVC impeded recovery via ‘double exposure’ of production loss and losing market access. Our results suggest that strategies to enhance resilience, with a particular focus on recovery, in GFVCs should promote trader loyalty, facilitate basin-scale collaboration and expand risk-targeted training.

Achieving the United Nation’s 2030 agenda which aims, among other goals, to ensure sustainable consumption and production patterns, requires a sustainable resource use model deployed at scale across global food systems. A circular bioeconomy (CBE) model of resource use has been proposed to reuse of organic waste in agricultural production to enhance food security. However, despite several initiatives recently introduced towards establishing a CBE in sub-Saharan Africa (SSA), minimal scientific efforts have been dedicated to understanding the association of CBE practices and food security. This study use data from 777 smallholder farm households from DRC, Ethiopia, Rwanda, and South Africa, to examine associations between three CBE practices (use of organic waste as compost, as livestock feed, and sorting waste) and household food security. Using different regression and propensity score matching models (PSM). Result reveal that using CBE practices more likely adds a 0.203 score of food insecurity access prevalence (HFIAP), 1.283 food insecurity access scale (HFIAS-score) and 0.277 for household dietary diversity score (HDDS) among households using CBE practiced groups. Associations regarding using organic waste as compost are generally positive but insignificant, while those with sorting waste are significantly and consistently negative. Thus, CBE innovations aiming to enhance household food security could prioritize organic waste valorization into livestock feed consider socio economic aspects such as access to land, access to market, education level, using mobile phone, income and city regions where interventions took place. However, prior sorting of waste is necessary to enable effective waste valorization.

Transitioning toward more sustainable livelihoods requires tackling complex challenges in innovative ways. Positioned at the intersection of innovation and transition studies, transdisciplinary research (TD) has surfaced as a method to confront sustainability challenges by integrating various scientific disciplines and engaging non-academic stakeholders. Currently, there is a growing call from both policy makers and research funders to assess the effects of TD research, especially its societal impacts. However, TD research typically involves local projects where the context may substantially shape the effects of the research conducted. In this paper we explore how understanding the context factors of a TD project contributes to the understanding of its effects. We built a working model, based on different established concepts from policy studies to conceptualize context and effects of TD project. We applied the model to a comparative case study of two regional sub-projects of one large TD project on circular bioeconomy for sustainable agriculture in Sub Saharan Africa. The core concept and design were the same for both subprojects, but they achieved different effects. We studied the differences in context factors to explain this variation. We found that a strongly developed public and private sector and access to a variety of action resources such as political support or laws, supported the implementation of innovations as well as dialogue with policy. Nevertheless, a strong public sector can also hinder a project's success, if the interest of the government is not in line with the interests of the project. Further, we found that TD projects may achieve learning and social effects by tackling certain gaps in action resources. Our findings highlight that taking the context of a project into account is key to understanding the scope of action and possibilities of a project. Thus, the context should be considered not only when planning but also - and especially - when evaluating a TD project.

This 68-country survey (n = 71,922) examines how people encounter information about science and communicate about it with others, identifies cross-country differences, and tests the extent to which economic and sociopolitical conditions predict such differences. We find that social media are the most used sources of science information in most countries, except those with democratic-corporatist media systems where news media tend to be used more widely. People in collectivist societies are less outspoken about science in daily life, whereas low education is associated with higher outspokenness. Limited access to digital media is correlated with participation in public protests on science matters.

Within the circular economy framework in Africa, sustainable waste management can contribute to improving the environment and creating green jobs. However, recycling activities are mostly carried out by informal workers, who are often forgotten in discussions about the circular economy. To ensure the development of a socially just circular economy, their voices must be heard and their needs accounted for. This study took place in Rwanda, a circular economy leader in Africa, and explored the experiences of workers engaged in biowaste recycling, with a particular focus on the distinctions between the experiences of female and male workers. We used photovoice as a methodology, allowing waste workers to visually report on the benefits and drawbacks of being involved in biowaste recycling. Seventeen waste recyclers took pictures representing different working experiences, which was followed by individual in-depth interviews to elicit the meaning behind each picture. Data analysis consisted of a reflexive thematic content analysis of interview transcripts and a participatory data analysis with the workers. The results show that the workers valued their jobs for their social relations at work, being responsible for a task, being productive, and generating savings. Workers negatively highlighted the health risks associated with waste sorting, difficult working conditions, and low salaries. We found gendered differences in workers' marital status and access to paid work opportunities. Although working in waste recycling encompasses occupational risks, this photovoice study highlights that access to work improves workers' relative well-being and that this type of circular economy can help create meaningful jobs.

Addressing socio-environmental challenges requires a multifaceted approach and a comprehensive understanding, which is precisely what transdisciplinary research can provide. The transdisciplinary approach, however, brings new challenges to early career researchers, who have to acquire the necessary methods and skills while conducting their ongoing research. Along with increasing access to resources and training, guidance from supervisors and informal exchange with other transdisciplinary early career researchers play key roles in effectively supporting them.

•By applying multivariate probit combination, sorting organic from inorganic waste and using organic waste as compost had contributed to success in engagement in circular bio economy (CBE) practices in Democratic Republic of Congo (DRC), Ethiopia, Rwanda, and South Africa.•Sorting waste and using organic waste as livestock feeds contributed to engagement in CBE practices.•Using organic waste as compost and livestock, feed had the lowest likelihood of success in engagement in CBE practices.•CBE innovations intending to achieve circular food systems through promoting combinations of CBE practices among smallholders, stand higher chances to succeed, more so if engaged in sorting waste and using organic waste as compost.•Categorical analysis also gives distinct predictions of what could naturally happen concerning combinations of CBE practices being discretely possible for smallholder households.

Increasing global food insecurity amidst a growing population and diminishing production resources renders the currently dominant linear production model insufficient to combat such challenges. Hence, a circular bioeconomy (CBE) model that ensures more conservative use of resources has become essential. Specifically, a CBE model that focuses on recycling and reusing organic waste is essential to close nutrient loops and establish more resilient rural-urban nexus food systems. However, the CBE status quo in many African food systems is not established. Moreover, scientific evidence on CBE in Africa is almost inexistent, thus limiting policy guidance to achieving circular food systems. Using a sample of about 2,100 farmers and consumers from key food value chains (cassava in Rwanda, coffee in DRC, and bananas in Ethiopia), we explored existing CBE practices; awareness, knowledge, and support for CBE practices; consumers’ opinions on eating foods grown on processed organic waste (CBE fertilizers), and determinants of such opinions. We analysed data in Stata, first descriptively, and then econometrically using the ordered logistic regression, whose proportional odds assumption was violated, thus resorting to the generalized ordered logistic regression. Results show that communities practice aspects of CBE, mainly composting, and are broadly aware, knowledgeable, supportive of CBE practices, and would broadly accept eating foods grown CBE fertilizers. Households with heads that used mobile phones, or whose heads were older, or married, or had a better education and agricultural incomes were more likely to strongly agree that they were knowledgeable and supportive of CBE practices and would eat CBE foods (foods grown on processed organic waste). However, the reverse was true for households that were severely food insecure or lived farther from towns. Rwandan and Ethiopian households compared to DRC were less likely to eat CB foods. Policies to stimulate CBE investments in all three countries were largely absent, and quality scientific evidence to guide their development and implementation is currently insufficient.

The larvae of the black soldier fly (BSFL, Hermetia illucens) efficiently close resource cycles. Next to the nutrient-rich insect biomass used as animal feed, the residues from the process are promising plant fertilizers. Besides a high nutrient content, the residues contain a diverse microbial community and application to soil can potentially promote soil fertility and agricultural production through the introduction of beneficial microbes. This research assessed the application of the residues on plant-associated bacterial and fungal communities in the rhizosphere of a grass-clover mix in a 42-day greenhouse pot study. Potted soil was amended with BSFL residues (BR+) or conventional compost (CC+) produced by Rwandan waste management companies in parallel to residues and compost sterilized (BR-, CC-) by high-energy electron beam (HEEB) as abiotic controls. The fertilizers were applied at a rate of 150 kg N ha(-1). Soil bacterial and fungal communities in both fertilizer and soil were assessed by high-throughput sequencing of ribosomal markers at different times after fertilizer application. Additionally, indicators for soil fertility such as basal respiration, plant yield and soil physicochemical properties were analyzed. Results showed that the application of BSFL residues influenced the soil microbial communities, and especially fungi, stronger than CC fertilizers. These effects on the microbial community structure could partly be attributed to a potential introduction of microbes to the soil by BSFL residues (e.g., members of genus Bacillus) since untreated and sterilized BSFL residues promoted different microbial communities. With respect to the abiotic effects, we emphasize a potential driving role of particular classes of organic matter like fiber and chitin. Indeed, especially taxa associated with decomposition of organic matter (e.g., members of the fungal genus Mortierella) were promoted by the application of BSFL residues. Soil fertility with respect to plant yield (+17% increase compared to unamended control) and basal respiration (+16% increase compared to unamended control) tended to be improved with the addition of BSFL residues. Findings underline the versatile opportunities for soil fertility arising from the application of BSFL residues in plant production and point to further research on quantification of the described effects.

Transdisciplinary research (TDR) projects integrate several disciplines as well as non-academic actors. Researchers claim that TDR projects are key for tackling complex sustainability issues. We study the effects and the factors influencing the effects of TDR projects in transnational research for development between the global North and the global South (North-South), as well as TDR projects conducted within the global North. This article explains our conceptual approach and presents selected findings.

The European Union's 2030 climate and energy package introduced fundamental changes compared to its 2020 predecessor. These changes included a stronger focus on the internal market and an increased emphasis on technology-neutral decarbonization while simultaneously de-emphasizing the renewables target. This article investigates whether changes in domestic policy strategies of leading member states in European climate policy preceded the observed changes in EU policy. Disaggregating strategic change into changes in different elements (goals, objectives, instrumental logic), allows us to go beyond analyzing the relative prioritization of different goals, and to analyze how policy requirements for reaching those goals were dynamically redefined over time. To this end, we introduce a new method, which based on insights from social network analysis, enables us to systematically trace those strategic chances. We find that shifts in national strategies of the investigated member states preceded the shift in EU policy. In particular, countries reframed their understanding of supply security, and pushed for the internal electricity market also as a security measure to balance fluctuating renewables. Hence, the increasing focus on markets and market integration in the European 2030 package echoed the increasingly central role of the internal market for electricity supply security in national strategies. These findings also highlight that countries dynamically redefined their goals relative to the different phases of the energy transition.

We investigate whether political ideology has an observable effect on decarbonization ambition, renewable power aims, and preferences for power system balancing technologies in four European countries. Based on the Energy Logics framework, we identify ideologically different transition strategies (state-centered, market-centered, grassroots-centered) contained in government policies and opposition party programs valid in 2019. We compare these policies and programs with citizen poll data. We find that ideology has a small effect: governments and political parties across the spectrum have similar, and relatively ambitious, decarbonization and renewables targets. This mirrors citizens' strong support for ambitious action regardless of their ideological self-description. However, whereas political positions on phasing out fossil fuel power are clear across the policy space, positions on phasing in new flexibility options to balance intermittent renewables are vague or non-existent. As parties and citizens agree on strong climate and renewable power aims, the policy ambition is likely to remain high, even if governments change.

The need to reduce greenhouse gas emissions in the electricity sector requires an increase in renewable generation capacity. However, the necessary space for power generation infrastructure can be in conflict with other uses of available land and different perspectives on how the development of renewable electricity should occur can lead to stakeholder oppositions. In an explorative study, I used Q methodology to inquire how affected stakeholders perceived the development of a photovoltaic solar park in Switzerland. This allowed me to identify possible ways to alleviate conflicts between designating land for agricultural use and renewable electricity development. The results show that while most identified worldviews among stakeholders agreed large roof surfaces should be prioritized for solar panels, remaining divergences explain tensions that threatened the realization of the solar park. Two perspectives were in conflict: on one side, actors defending a strict protection of agricultural land; on the other, actors who considered it appropriate to build solar panels on fields. The results also suggest that renewable energy expansion should preserve a balance between large-scale and small-scale photovoltaic power development to be socially acceptable amongst a broad spectrum of stakeholders.
