The 2030 Agenda includes 17 overarching Sustainable Development Goals (SDGs). These are integrated in nature, and a principle of indivisibility should guide their implementation. Yet, the 2030 Agenda itself does not provide guidance on what indivisibility means in practice, how the SDGs interact, or on how to assess these interactions. The fast-emerging field of what could be referred to as SDG interaction studies seeks to provide such guidance, but as of yet there is no general agreement on what it means to take an integrated approach to the SDGs. Hence, navigating the diverse research landscape on SDG interactions might prove challenging. This paper aims to decipher the literature on SDG interactions by providing an overview of the current research, based on a sample of 70 peer-reviewed articles. The review explores four themes in SDG interaction research by mapping: (i) policy challenges typically addressed, (ii) ways in which SDG 'interactions' have been conceptualized, (iii) data sources used, and (iv) methods of analysis frequently employed. Research gaps are identified, where perspectives largely missing include policy innovation, and integrated monitoring and evaluation. Further, few studies consider actor interactions, account for geographic spill-overs, analyze SDG indicator interactions, employ participatory methods, or take a whole-systems approach to the 2030 Agenda. Failing to address these gaps could lead to inefficient SDG implementation and delay goal attainment. Another contribution of the paper is a reading guide, proposing a way to decipher the literature along the themes emerging from the review, and offering a structure to code future papers.

The bio-based economy has been increasingly recognized in the sustainability debate over the last two decades, presented as a solution to a number of ecological and social challenges. Its premises include climate change mitigation, cleaner production processes, economic growth, and new employment opportunities. Yet, a transition to a bio-based economy is hampered by risk factors and uncertainties. In this paper, we explore the concept of a bio-based economy, focusing on opportunities of achieving sustainability, as well as challenges of a transition. Departing from an understanding of sustainability provided by the weak and strong sustainability paradigms, we first outline the definition and development of the bio-based economy from a theoretical perspective. Second, we use Sweden as an example of how a transition towards a bio-based economy has been evolving in practice. The review indicates that the proposed direction and strategies of the bio-based economy are promising, but sometimes contradictory, resulting in different views on the actions needed for its premises to be realized. Additionally, current developments adhere largely to the principles of the weak sustainability paradigm. In order for the bio-based economy to develop in accordance with the notion of strong sustainability, important steps to facilitate a transition would include acknowledging and addressing the trade-offs caused by biophysical and social limits to growth.

A transition to a bio-based economy would entail change in coupled social–ecological systems. These systems are characterised by complexity, giving rise to potential unintended consequences and trade-offs caused by actions aiming to facilitate a transition process. Yet, many of the analyses to date have been focusing on single and predominantly technological aspects of the bio-based economy. The main contribution of our work is to the development of an integrated understanding of potential future transition pathways, with the present paper focusing specifically on terrestrial biological resources derived from the forestry sector in Sweden. Desired change processes identified include a transition to diversified forest management, a structural change in the forestry industry to enable high-value added production, and increased political support for the bio-based economy concept. Hindrances identified include the ability to demonstrate added values for end consumers of novel biomass applications, and uncertainty linked to a perceived high level of polarisation in the forestry debate. The results outline how these different processes are interrelated, allowing for the identification of high order leverage points and interventions to facilitate a transition to a bio-based economy.

In response to the interconnected character of societal challenges, there is a growing interest in transdisciplinary sustainability research. However, for transdisciplinary research to be able to support the generation of new knowledge in a participatory and reflexive manner, a number of challenges have been identified in each stage of the transdisciplinary research process. In this paper, we respond specifically to the challenge of initiating transdisciplinary research projects, by proposing a process for performing transdisciplinary project scoping. Our group of early‐career researchers share experiences from scoping for transdisciplinary research potential, bridging local stakeholder needs with researchers’ interests across departments and national contexts. We present our methodological approach,which includes tools for stakeholder identification, systems thinking, and gap‐mapping. The approach was applied in the local context of the Navarino Environmental Observatory, Messinia, Greece. The findings identify regional sustainability concerns related to, for example, tourism, agriculture, and environmental management issues. The gap‐map highlights overlaps (e.g., in terms of existing research on the effects of agriculture on water resources), but also how previous research has been conducted on spatial and temporal scales not directly relevant to local actors. We believe that the approach can be used beyond this case study to identify the potential for problem‐oriented inter‐and transdisciplinary research.

There is a growing interest in the bio-based economy, evident in the policy domain as well as in the academic literature. Its proponents consider it an opportunity to address multiple societal challenges, and the concept has broad reach across different sectors of society. However, a potential transition process is also linked to areas of risk and uncertainty, and the need for interdisciplinary research and for the identification of potential trade-offs and synergies between parallel visions of the bio-based economy have been emphasized. The aim of this paper is to contribute to addressing this gap by using an approach combining tools for systems analysis with expert interviews. Focusing specifically on dynamics in the agricultural sector in Sweden, an integrated understanding of the social and ecological processes contributing to or hindering a transition in this area is developed, high order leverage points are identified, and potential impacts of proposed interventions explored. The paper also considers cross-sectoral linkages between the forestry and agricultural sectors.
