Tracking developmental progress is crucial to understanding how big data applications in smart farming are rapidly evolving with ongoing technological advancements. We conducted a bibliometric analysis of academic publications and documents published in Scopus-indexed peer-reviewed journals. A total of 2,154 publications, including journal articles (45 %), conference proceedings (30 %), book series (16 %), and books (9 %), were retrieved, with 96 % of the documents in the English language and two-thirds of the documents published within the last four years of this research study. The reviewed publications were predominantly focused on the disciplines of computer science (64 %), engineering (36 %), and agriculture and biological science (22 %). The contributions of authors from India, China, and the United States were the highest, accounting for half of the publications when combined. As an outcome of the bibliometric analysis, five research domains of big data, i.e., data-driven decision-making, sustainability and supply chain management, technology and innovation, data management and governance, and digital transformation were identified, suggesting positive development in this field. As an implication of this work, we have identified a need for greater global collaboration to achieve big data advancement and technology adaptation. We also discussed the implications of this work for research, practice, and policy. Despite the opportunities that big data brings for smart farming, economics, data governance, and data sharing and reliability remain prevalent issues.

Norway has a long tradition of using wood as the main construction material in residential houses and cabins; however, recycled wood is not easily available. This study aims to gauge consumers’ willingness to use recycled wood as construction material in houses and cabins, by applying the Diffusion of Innovations theory. Online surveys were distributed to 446 cabin-owners and 467 houseowners in Norway. The analyses revealed that more than half of the consumers are willing to use recycled wood in construction. Structural equation modeling results exhibited Relative Advantage over primary material and Compatibility with existing building materials as the strongest drivers of Adoption; however, Perceived Risk associated with recycled wood had limited effects. Consumers’ Green Values did not directly affect Adoption. Compatibility and Green Values had indirect effects on Adoption via Relative Advantage as a mediator. Our findings imply high readiness from end-consumers to use recycled wood in construction and renovation in private housing, exhibiting potential market avenues.

We conducted a multi-dimensional sustainability assessment of the status of <em>IR</em> of Uganda's banana fibre sector and identified strategic requirements to sustainably upscale production and processing. Systematically, we collected and analysed data obtained through resource mapping, interviews and FGDs to: (i) map biomass flows; (ii) map relations among actors; (iii) assess readiness of farmers to supply raw material; and (iv) describe, from a stakeholders’ perspective, the factors relevant in advancing the industry towards readiness. Results indicate that banana fibre biomass flows followed a complex pathway from pseudo-stem production to marketing and waste disposal, in which fibre processors were the most influential actors. Out of 102 farmers assessed, 40 % were ready (with <em>ability</em>) to sell pseudo-stems. Yet, over 70 % expressed interest to sell on condition of substantial price-increase. To achieve <em>IR,</em> various aspects were at nascent status of readiness but require attention: markets; actor partnerships; public awareness; human, technical and infrastructural capacity; and sustainability issues.
