    Materials & design (Elsevier, 2026)
    Polyphenol-rich Norway spruce bark extract, a side-stream from the forest industry, is used to create antimicrobial fiber materials for biomedical applications. Lyocell, viscose, and blend non-wovens are coated with the bark extract and commercial tannic acid (TA), which serves as a reference, using three different methods: impregnation, spray coating, and draw-down coating. The antimicrobial efficacy of the coated materials is assessed against a Gram-negative (Escherichia coli) and a Gram-positive (Staphylococcus aureus) including methicillin-resistant (MRSA) bacteria. Antiviral activity is tested against an enveloped coronavirus (HCoV-OC43) and a non-enveloped Coxsackievirus B3 (CVB3). The bark extract demonstrates strong antimicrobial activity, with the best results achieved on viscose and blended materials using draw-down or impregnation methods. Overall, draw-down coating provides the best performance regarding both antimicrobial and surface properties. Compared to tannic acid, the bark extract is markedly more effective against viruses, an effect attributed to its complex polyphenolic structure. The results indicate that Norway spruce bark extract is a promising bio-based agent for developing antimicrobial materials for healthcare

    Frontiers in sustainable food systems (Frontiers Media S.A., 2026)
    This perspective paper draws on insights from a 2024 symposium entitled ‘Exploring methods for researching shifts in knowledge production for agroecology transition’. The symposium critically examined emerging conceptual and methodological challenges arising from combining agroecology with living labs and research infrastructures as key instruments promoted within EU policy to strengthen Agricultural Knowledge and Innovation Systems (AKIS). Through presentations, group discussions, and iterative reflections, we identified four key tensions: structural constraints limiting farmers’ agency within living lab approaches, the problematic nature of AKIS as supposedly neutral frameworks, the oversimplification of transition frameworks as linear rather than overlapping categories, and risks of definitional dilution or cooptation. We then demonstrate that these tensions are not unique to agroecology, bridging the concepts and methods within agroecology research with those used in other fields of sustainable food system transition research, such as transdisciplinary research and sustainable transitions. This conceptual mapping of shared tensions reveals opportunities for mutual learning. Bridging these fields would help create clarity at the conceptual and methodological levels, ultimately strengthening the theoretical foundations and enabling more nuanced approaches to food system transition research.
  • Challenges and limitations of introducing pigeonpea as a new crop into smallholder farming systems through farmer‐to‐farmer education in Zambia

    Plants, people, planet (John Wiley & Sons, 2026)
    Societal Impact Statement Legume plants offer generous benefits for both the planet and people by supporting sustainable farming, food and feed systems through their ability to symbiotically fix atmospheric nitrogen. While grain legumes are cultivated and consumed globally, their adoption, market development, and integration into cropping systems vary. In Zambia, pigeonpea remains an underutilised legume crop despite its suitability for semiarid conditions and potential to diversify food and income sources. We implemented farmer field schools in the Eastern province of Zambia to introduce pigeonpea, strengthen farmer knowledge, and explore how participatory learning can support its adoption and early-stage value chain development. Summary Farmer field schools (FFSs) are transformative, participatory approaches to adult agricultural education that effectively promote farmers' learning and capacity building and empower farming communities with practical knowledge. Here, we present a case study of FFSs in the Katete district, Eastern province of Zambia, focused on good pigeonpea agronomic practices and the value chain. Three FFSs were established, focusing on pigeonpea variety trials, biological pesticides, and a pigeonpea-specific rhizobial inoculant development and testing. Farmers received hands-on training and resources and were guided through community-led trials. Extreme weather conditions, free-grazing livestock, an underdeveloped pigeonpea seed value chain, and a poor seed system hindered the implementation of the FFSs. Despite the challenges encountered, we successfully designed and tested pigeonpea-specific rhizobial inoculants, trained farmers in good agronomic practices such as biological pest control, and provided access to seed of improved pigeonpea varieties. To strengthen the pigeonpea seed value chain, a seed dehuller is now available to farmers. Pigeonpea FFSs will support crop and food diversification, improve soil fertility and sustainable agriculture, and may increase household income.
