- The United Nations identifies the food crisis as one of the primary overarching challenges facing the international community. Different stakeholders in the food system have widely different perspectives and interests, and challenging structural issues, such as the power differentials among them, remain largely unexamined. These challenges make rational discourse among food system actors from different disciplines, sectors and levels difficult. These challenges can often prevent them from working together effectively to find innovative ways to respond to food security challenges. This means that finding solutions to intractable and stuck issues, such as the food crisis often stall, not at implementation, but at the point of problem identification. Food system sustainability means very different things to different food system actors. These differences in no way undermine or discount the work carried out by these players. However, making these differences explicit is an essential activity that would serve to deepen theoretical and normative project outcomes. Would the impact and reach of different food projects differ if these differences were made explicit? The purpose of this initial part of a wider food system research project is not to search for difference or divergence, with the aim of critique, but rather to argue that by making these differences explicit, the overall food system project engagement will be made more robust, more inclusive and more encompassing. This paper starts with some discussion on the different food system perspectives, across scales, regions and sectors but focuses primarily on the design of processes used to understand these divergent and at times contradictory views of what a sustainable food system may be. This paper draws on ongoing work within the Mistra Urban Futures project, using the food system projects in cities as diverse as Cape Town, Manchester, Gothenburg and Kisumu as sites for this enquiry.

- Several strains from the genus Trichoderma (Ascomycetes, Hypocreales) are commercially used as biocontrol agents, e.g. in formulations containing the two Trichoderma strains IMI206039 (Hypocrea parapilulifera B.S. Lu, Druzhinina & Samuels) and IMI206040 (T. atroviride P. Karst). To quantify the presence of the two isolates after application, we developed primers for SCAR markers (Sequence-Characterised Amplified Region). In order to quantify both fungal strains simultaneously, we also designed fluorophore-labelled probes distinguishing the two strains, to be used in combination with the SCAR primers. In incubations of two different soils, artificially inoculated and maintained under controlled conditions, the quantification through amplification with the SCAR markers in qPCR and through colony-forming units from plate counting correlated well. Further tests of the markers on samples taken from a golf green treated with a product containing both strains indicated that the two biocontrol strains did not establish, either on the golf green or in the surrounding area.

- There is a considerable amount of literature dealing with inference about the parameters in a heteroscedastic one-way random-effects ANOVA model. In this paper, we primarily address the problem of improved quadratic estimation of the random-effect variance component. It turns out that such estimators with a smaller mean squared error compared with some standard unbiased quadratic estimators exist under quite general conditions. Improved estimators of the error variance components are also established.

Diagnostic, regenerative or fossil-free - exploring stakeholder perceptions of Swedish food system sustainability
- 2023

Ingår i: Ecological Economics. - : Elsevier B.V.. - 0921-8009 .- 1873-6106. ; 203

Tidskriftsartikel (refereegranskat)abstract
- In an analysis of food system sustainability challenges and solutions among Swedish food system actors using Q-methodology, five perspectives were identified. One of the main three perspectives placed the highest priority on reduced meat consumption, food waste, and climate impact in agriculture, but downplayed strategies highlighted in the national food strategy and social aspects, and can be interpreted as a diagnostic climate mitigation-oriented perspective that does not reflect current negotiated policy processes or ‘softer’ values of food. In an alternative regenerative perspective, industrialized large-scale farming and lack of internalization of external costs were regarded as the main problems, and diversity, soil health, and organic farming as the main solutions. Proponents of a third perspective regarded phasing out fossil fuels, increased profitability of companies, increased meat production, and self-sufficiency as high priorities. These contrasting views can be a major barrier to transforming the Swedish food system. However, a number of entry points for change (i.e. aspects highly important for some and neutral for others) were identified, including focusing on healthy diets and increased production of fruit and vegetables. Focusing on these can build trust among stakeholders before moving to discussions about the larger and more sensitive systemic changes needed. © 2022 The Authors

- This 40th anniversary issue of BGSS highlights some of the tenets of the complexity that make sustainability a ‘wicked problem’ through a number of different perspectives, many of which have to date been pushed into the background amidst an otherwise exceptionally rich geographical literature on sustainability. The editorial task included procurement, administration and scientific processing of 12 articles from 25 authors as follows: (1) Mirek Dymitrow, Keith Halfacree – “Sustainability–differently”; (2) Slobodan Arsovski, Michał Kwiatkowski, Aleksandra Lewandowska, Dimitrinka Jordanova Peshevska, Emilija Sofeska, Mirek Dymitrow – “Can urban environmental problems be overcome? The case of Skopje—world’s most polluted city”; (3) Janis Birkeland – “Challenging policy barriers in sustainable urban design”; (4) Elizabeth Dessie – “Applying resilience thinking to ‘ordinary’ cities: A theoretical inquiry”; (5) Madeleine Eriksson, Aina Tollefsen – “The production of the rural landscape and its labour: The development of supply chain capitalism in the Swedish berry industry”; (6) Stina Hansson – “The role of trust in shaping urban planning in local communities: The case of Hammarkullen, Sweden”; (7) Shelley Kotze – “The place of community values within community-based conservation: The case of Driftsands Nature Reserve, Cape Town”; (8) Davide Marino, Luigi Mastronardi, Agostino Giannelli, Vincenzo Giaccio, Giampiero Mazzocchi – “Territorialisation dynamics for Italian farms adhering to Alternative Food Networks”; (9) E. Gunilla Almered Olsson – “Urban food systems as vehicles for sustainability transitions”; (10) George Mark Onyango – “Urban public transport in informal settlements: Experiences from Kisumu City, Kenya”; (11) Christian M. Rogerson – “Informality and migrant entrepreneurs in Cape Town’s inner city”; (12) Marcin Wójcik, Karolina Dmochowska-Dudek, Pamela Jeziorska-Biel, Paulina Tobiasz-Lis – “Understanding strategies for overcoming peripherality: A Polish experience of transition”. The articles have been reviewed by a cadre of 40 reviewers from 34 academic institutions across 14 countries.

Tidskriftsartikel (refereegranskat)abstract
- International studies have noted shortcomings in food safety knowledge and behaviour among university students. In general students do not constitute a pronounced risk group but there are wider implications. In a foreseeable future some of them will become pregnant and a majority will be responsible for vulnerable groups in their near environment. A crucial question exists, therefore, about their food safety knowledge and safe food handling practices. The aim of this study is to investigate food safety knowledge, sources thereof and self-reported food safety behavior among university students in Sweden. A quantitative study design using a web-based questionnaire was chosen as the data collection method. The questionnaire was distributed through social media and e-mail. Among the 606 respondents from 24 Swedish universities 80% were 18-30 years and 78% were women. The average number of correct answers on the knowledge questions was 7.61 out of 12 (63.4%). The foremost source of food safety knowledge was "Family and friends" (45%). Just 21.1% reported Food safety education as a source, although 35.6% had experience of a course in food hygiene/safety and/or microbiology. Respondents who reported "Family and friends" to be the foremost food safety source of knowledge also got a significantly lower rate of correct answers. Students who estimated their food safety knowledge to be good also had more correct answers. Experience of food safety education at secondary school/university/working place/polytechnic school significantly correlated with more correct answers on the knowledge questions and indicated a safer self-reported behaviour. Those with fewer correct answers also reported more unfavourable behaviours. The present study indicates that education promotes more optimal behaviors. The authors would suggest a more systematic food safety education at younger ages.

- Food and meals are central elements in our lives: a source of pleasure, a social activity and a bearer of culture. Our eating habits are also very important to health, which implies that the organization and content of meals is a prerequisite for well-being and learning. Schools, in particular, have unique opportunities to promote healthy lifestyles, help develop good eating habits and raise environmental and climate awareness among children and youths by embedding food in a wider context. Unsurprisingly, there is also an increasing interest in school meals and food-related education among researchers, many of whom agree that the quality of school meals can be seen as one of the most accurate indicators of the cities’ sustainability potential. Systematic quality work, however, requires shared targets and ambitions, regular quality checks and discussions on development and improvement. In that vein, the City of Gothenburg has launched the project Urban Rural Gothenburg, which assembles, develops, tests and implements new solutions for the city’s public kitchens. This involves climate-smart and environmentally sound perspectives and programs regarding meal planning, food procurement, food preparation and food-related teaching and learning. One important approach deals with the normalization of increased vegetarian consumption and greater awareness of food’s origins and travel from farm to table. Another approach deals with conscious choices of raw materials that are beneficial for both the environment and health. A third notable approach focuses on new ways of handling food waste to reduce climate impact. In line with the third Sustainable Development Goal, this presentation captures and reaffirms the fundamental assumptions and methods involved in Gothenburg’s work with food sustainability in public kitchens, with an emphasis on health and climate as cross-cutting issues that matter to us all.
