The future role of reverse logistics as a tool for sustainability in food supply chains: a Delphi-based scenario study

Purpose The importance of integrating sustainability into business activities rises continuously. In addition to an established focus on forward logistics, there is a growing awareness of reverse logistics. Reverse logistics ensures sustainable practices and increases competitiveness for companies, but it also comes with challenges. Therefore, the implementation of reverse logistics is associated with uncertainties. This paper aims to fill this gap by analyzing the development and comprehensive potential of reverse logistics as a sustainability tool. Design/methodology/approach To bridge the research gap, a real-time Delphi study was conducted. Through an extensive desk research, semi-structured interviews and an expert workshop, 14 projections for the German food sector of 2040 were created. A total of 49 experts in the field of logistics, reverse logistics and food logistics assessed the future projections concerning estimated probability, impact and desirability of occurrence. Findings The findings derived lead to three possible future scenarios as well as potential drivers and barriers that food companies, the government and society need to consider to enable a successful transition toward implementing reverse logistics in food supply chains. Originality/value The study examined the future role of reverse logistics as a sustainability tool in food supply chains. The results serve as a framework for decision-making on the sustainable orientation of business practices, leading to increased competitiveness and resilient business strategy. Several implications are derived for practitioners, policymakers and society to promote reverse logistics. Methodologically, this study extends existing Delphi methods by conducting a quantitative dissent and sentiment analysis, considering various surface-level and deep-level diversity characteristics.

Trends and Perspectives in Education for Sustainable Development in the Teaching of Geography in Spain

The UN’s Sustainable Development Goals (SDGs) should be known and assumed by the community of geography teachers in all levels of education as a key part of their educational work. In order for well-grounded SDGs-related geographic didactic proposals to be presented, and for researchers in didactics to find a way to incorporate and promote SDG-related contents in daily teaching, a thorough knowledge of the relevant geographical literature is mandatory. The aim of this work is to present the results of a review comprising 1183 papers submitted to the 22 congresses on the didactics of Geography organised by the Spanish Association of Geography working group in didactics from 1988 to 2019, as well as 186 works published in the only Spanish journal on the Didactics of Geography, Didáctica Geográfica. This analysis focuses on the contents addressed in these studies, as well as on the skills and didactic strategies related to the teaching of SDGs. It was found that most SDGs-related contributions in Spain deal with landscape and the environment. Regarding skills, it was concluded that much remains to be done concerning Education for Sustainable Development (ESD). Finally, the current and future role of ESD in geographical teaching in Spain is assessed.

Gut Microbiota Parameters Potentially Useful in Clinical Perspective

Interest in gut microbiota analyses is at an all-time high. Gut microbiota is thought to relate to an increasing range of diseases of interest to physicians and nutritionists. Overweight, obesity, response to diet, metabolic syndrome, low grade inflammation, diabetes and colon neoplasms could maybe be observed in microbiota if affordable markers were available. Possible biomarkers like the Firmicutes/Bacteroidetes ratio, the Gram-positive/Gram-negative ratio, the Prevotella/Bacteroides ratio, and the Fusobacterium nucleatum/Faecalibacterium prausnitzii ratio are here reviewed in a narrative way in the attempt to highlight their possible future role in routine practice and clinically relevant diagnostics.

A Critical Review of the Role of Repair Cafés in a Sustainable Circular Transition

Extending the useful life of consumer products is a critical element in the circular economy. Although commercial repair is an established part of the global economy, the repair is often conducted informally. This means that non-commercial repair ecosystems exist, including the international network of repair cafés, spreading worldwide to over 2000 repair cafés in 37 countries (April 2021). As the first review on this topic, this article investigates and gains more knowledge about repair cafés, and critically assesses their role as a sustainability initiative, i.e., how the concept may translate into a broader sustainability context. A systematic literature review (2010–2020) was conducted, including 44 articles in descriptive and content analyses. The bibliometric data revealed an increase in the number of publications on repair cafés, particularly over the last four years, indicating that repair cafés as a research topic have started to gain attention, and this is likely to grow in numbers. However, the significant number of different places of publication indicates that this is not (yet) a well-established field with defined research channels. The content analysis revealed that the concept has spread to a range of different contexts, beyond the original scope, influencing the mindset and acts of a broad field of practitioners. This indicates a wide range of possibilities for the expansion of the concept of repair cafés, bringing different expectations on calling into question the future role of repair cafés. However, the aims of the people involved in repair cafés span from the altruistic and strategic, over personal gains, to critical consumer, financial and educational aims. This may challenge repair cafés’ future role(s), i.e., ambitions set by the international organisation of repair cafés. Notably, the ambition for actors at the micro-level is to feed in data on repair and achieve ‘collaborative repair’, as the aims of the people involved are complex, and their expectations lack alignment, both vertically and horizontally.
