Purpose: The paper identifies, outlines, and categorises establishment and operational factors that contribute to successful agricultural on-farm demonstration. Design/Methodology/approach: The paper is based on a literature review on demonstration activities and meta-analysis of 24 original case study reports from 12 European countries. Findings: Based on a combination of deductive and inductive analysis, the success determinants are classified into nine critical success factors deemed important in designing an on-farm demonstration event (the ‘Nine Ps'): Purpose, Problem, Place, Personnel, Positioning, Programme, Process, Practicalities, Post-event engagement. Each factor (‘what') is framed in terms of success principles to provide a guide to its enactment (‘how'). Practical implications: The results of the analysis can serve as a practical decision-support tool for organisers and evaluators of on-farm demonstration events. Theoretical implications: The paper broadens the perspective on the character, interlinkages, and relative importance of the factors underlying demonstration and their successful application within the agricultural knowledge and innovation system. Originality/Value: The paper addresses the deficit of comprehensive empirical studies investigating on-farm demonstrations by offering a rich research-based analysis of the factors and principles underlying their successful implementation.

Purpose: To assess the inclusivity of on-farm demonstration across Europe, in relation to age, gender, and geographical location of participants. Methodology: The paper is based on a survey of 1162 on-farm demonstrators (farmers and organisations) and three supra-regional workshops. Findings: Overall, on farm-demonstrations were found to be engaging young(er) farmers who are at a career stage of being able to implement long-term innovations. However, across Europe demonstrations were primarily attended by men. On-farm demonstrations were most common in Northern Europe, where advisory services brought together multiple AKIS actors. There were fewer on-farm demonstrations in Southern Europe, where demonstrations were more likely to be led by research institutes or individual farmers. Eastern Europe is notable for greater diversity in terms of gender and age of demonstration participants. Within countries, on-farm demonstrations occurred more frequently in regions of high agricultural profitability; more remotely located farmers had fewer opportunities to participate. Practical implications: Demonstrations led by public and privately funded advisory services appear to attract primarily male farmers, thus reinforcing gendered patterns of participation in European agriculture. The location of advisory services and research institutes in high profitability locales disproportionately privileges farmers located there. More targeted efforts are required to ensure the participation of farmers who are female, older and located in less productive regions. Theoretical implications: The paper draws attention to the lack of inclusivity of on-farm demonstration, developing a conceptual framework based on Lukes’ three faces of power. Originality: The paper utilises the first European-wide inventory of on-farm demonstration to assess inclusivity.

Nature-based solutions (NBSs) involving tree-based interventions deliver multiple community benefits, yet evidence linking these benefits to underlying socio-ecological vulnerabilities remains limited. This study synthesised metadata from 131 European treescape NBS case studies spanning eight biogeographical regions using reverse-logic, thematic qualitative analysis. Case studies were identified via adapted PRISMA guidelines from open-access repositories, with community benefit themes categorised and mapped spatially across bioregions. The analysis revealed eleven principal community benefit categories and distinct region-specific patterns: Mediterranean interventions primarily mitigated extreme heat and drought vulnerabilities, whilst Alpine projects addressed slope stability and hazard reduction. The Continental and Atlantic regions emphasised social cohesion, recreational access, and the preservation of cultural heritage. The reverse-logic methodology successfully identified underlying socio-ecological vulnerabilities through systematic analysis of observed benefit profiles across diverse European contexts. This approach provides evidence-based guidance for designing location-sensitive treescape NBS that advance environmental research and public health objectives. The findings establish a methodological foundation for future assessments of NBS effectiveness and for refining location-specific treescape interventions that address community vulnerabilities and enhance adaptive capacity.
