(1) The amount of plastic discharges in the environment has drastically increased in the last decades negatively affecting aquatic ecosystems, societies, and the world economy. The policies initiated to deal with this problem are insufficient and there is an urgency to initiate local actions based on a deep understanding of the factors involved. (2) This paper investigates the potential of massive open online courses (MOOCs) to spread environmental education. Therefore, the conclusions drawn from the implementation of a MOOC to combat the problem of marine litter in the world are presented. (3) This work describes the activity of 3632 participants from 64 countries taking an active role presenting useful tools, connecting them with the main world associations, and defining applied action plans in their local area. Pre- and post-questionnaires explore behavioral changes regarding the actions of participants to combat marine litter. The role of MOOCs is contrasted with social media, formal education, and informal education. (4) Findings suggest that MOOCs are useful instruments to promote environmental activism, and to develop local solutions to global problems, for example, clean beaches, supplanting plastic bottles, educational initiatives, and prohibition of single-use plastic.

Payments for ecosystem services (PES) are currently being discussed as one of the most promising tools in environmental and sustainability governance. However, much criticism has been voiced against overly optimistic assumptions of PES’ management potential towards sustainability. Several contributions to the debate show that PES fail both in reducing poverty and strengthening social justice. Additionally, they neglect problems of deliberation in decision-making, as well as the legitimacy of the applied environmental practices. Our empirical investigation on participatory and deliberative structures in already existing PES initiated by non-state actors contributes to the latter body of research. Based on the assumption that playing an active part in scheme design facilitates the consideration of justice and fairness, our case studies from Germany and the UK. present interesting results on the involvement of conflicting interests and their argumentation in the design process. Summing up these findings, we conclude that paying for ES rarely contributes to sustainable development in and of itself, but deliberatively designed schemes provide a formal setting to take aspects of justice into account.

Anthropogenic influences and the excessive input of reactive nitrogen compounds into the environment have already severely destabilized the natural nitrogen cycle. Especially in northwestern Germany, many water bodies are polluted by nitrate, inducing negative effects on the ecosystem and drinking water as well as possible risks to human health. In cooperation with almost 600 citizens and 200 students, this issue was addressed in a citizen science project carried out by the Universities of Osnabrück and Oldenburg, gathering 8754 nitrate measurements at 545 monitoring sites from September 2019 to March 2021. The data were used to evaluate the potential of citizen science for research on nitrogen pollution of water bodies. In a pre-investigation, we proved that nitrate test strips are suitable as a measurement method for the citizen science approach to provide an overview of nitrate pollution. We then analyzed whether the citizen science approach can be used to establish an area-wide representative measurement network, to what extent the data can be used for spatial and temporal analyses, and whether the data are consistent with the results of other monitoring initiatives. For this purpose, geoprocessing tools, such as spatial joins and heatmaps, were combined with descriptive statistics and nonparametric statistical tests. Although it was not possible to establish a representative monitoring network due to the uneven spatial distribution of monitoring sites, a large part of the intended area was covered by monitoring sites. Thus, the data provide a good overview of the nitrate pollution in the region and shed light on influencing factors. Spatial impacts, such as land cover and use and hydrogeological conditions, as well as seasonal impacts were statistically evidenced with the citizen science data. Furthermore, the consistency of the data with the measurement results of established measurement initiatives confirm the quality of the citizen science dataset. Accordingly, citizen science can be used to investigate spatial and temporal factors influencing nitrogen pollution, and thus contributes to water conservation research as an innovative approach.

The complexity of sustainable development and societal transitions require both analytical understandings of how coupled human-environment systems function and transdisciplinary science-to-practice approaches. The academic discourse has advanced in developing a framework for defining success in transdisciplinary research (TDR). Further empirical evidence is needed to validate the proposed concepts with TDR case studies. This paper applies a widely used TDR framework to test and critically evaluate its design principles and criteria of success with five TDR case studies the author is intimately familiar with. Overall, the design principles of the framework are validated for the five cases. Additional design principles are derived from the case analysis and proposed to complement the applied framework: (1) A project origin from society as opposed to with and for society; (2) Quickly available initiation funding; (3) Flexibility in time, objectives and methods throughout the research process; (4) Acceptance of process vs. project results; (5) Inclusion of public science communication; and (6) A demand-driven transition to a prolonged or new project partnership. The complementing principles are proposed for integration in the applied framework and are subject to further empirical testing. The reflexive empirical approach I have taken in this paper offers a key step towards removing institutional barriers for successful TDR, demonstrating how conceptual frameworks can be applied.

A new brewery is founded in Brazil every two days. Yet with climate change, drinking water is increasingly scarce. Previous studies have begun exploring the brewing industry, but an examination of circular economy initiatives in Latin America is lacking, particularly during the COVID era. This study analyzes strategic implications of circular economy initiatives, together with their role in the coevolution of the craft beer sociotechnical system in Brazil from a resource perspective during the COVID pandemic. Using a qualitative methodology based on analytic induction, 11 in-depth semi-structured interviews were carried out with key actors from the craft beer sociotechnical system in Guarapuava. For the content analysis, we triangulated the interviews with an analysis of 74 related documents. We found evidence of circular economy practices and sociotechnical transitions with the simultaneous coevolution of the system actors. Increasing rejection of the linear take–make–waste economy was observed as subject organizations largely adopted a regenerative model reducing operational waste. Hence, entrepreneurial innovation was apparently crucial for resource allocation during the COVID era. This work contributes to further understanding resource configurations in the circular economy, with practical implications for integrating sustainability into strategy, business models, and production.

This article discusses the strategies that sustainable entrepreneurs use to interact with their environment in the Dutch construction industry. The Dutch construction industry is under great pressure to move towards sustainability, and entrepreneurs are believed to be able to play a large role in this transition by introducing new products and new business practices. But how can entrepreneurs prosper in an environment that is not geared up towards such a change? And which strategies do they use to bend conditions in their favor? In this article we make use of the Market and System Failure Framework to analyze the pressures that entrepreneurs are confronted with when introducing sustainable innovations. We recognize that these pressures can be seen as bottlenecks, but that market and system failures can also create entrepreneurial opportunities. We interviewed 16 entrepreneurs in the Dutch construction industry to determine the influences they experienced from their environment and the strategies they use to deal with these. We conclude that we can distinguish between system building and following entrepreneurs, where the former aims to build a new system to challenge the old one, whereas the latter rather makes use of existing structures to build a business. We find that both strategies can be successful and that overall, the entrepreneurs confirm the belief that sustainability on people, planet and transparency aspects, can contribute very well to the long term profitability of the businesses the entrepreneurs are running. These in-depth insights into the influences from the context on the one hand, and the entrepreneurs’ strategic reactions on the other hand, contribute to our understanding of the interactions between entrepreneurs and the system context. This can help us to more effectively stimulate and support innovating entrepreneurs to contribute to the transition towards sustainability.

In the past three decades, there has been increasing research carried out on the role of heritage and its processes in achieving broader sustainable development objectives beyond heritage conservation. As part of this movement, people-centered approaches and participation have been widely integrated into international regulations and guidelines on heritage management, stimulating the implementation of case studies-based research worldwide. Despite the wide advocacy of participatory heritage practices’ contributions to more inclusive and culturally sensitive local development in a great variety of projects, there is limited research into the roles these practices can have in addressing sustainability objectives. How are these roles addressed in international heritage regulatory frameworks, and what forms of participation are promoted for their fulfillment? This paper seeks to answer this research question through a content analysis of international declarations, conventions, guidelines, and policy documents focused on the roles and forms of participation that are promoted. A crossed-matched analysis of results reveals that active forms of participation are those most used to promote all roles and subcategories of participation, as a right, as a driver, and as an enabler of sustainable development. However, fewer active forms are presented as complementary at different stages of sustainability-oriented heritage practices. Moreover, a higher incidence of generic forms of participation can be observed in documents addressing international stakeholders, while partnership and intervention are to be found in those targeting regional and local actors. Nevertheless, the low incidence of decisional forms of participation confirms the challenges of power-sharing at all scales. Trends and influences are highlighted, informing heritage research, governance, and policymaking, but also revealing gaps and ambiguities in current regulations that further research encompassing a larger number of documents might confirm.
