Purpose: The aim of the paper is to analyse the use of Communities of Practice and Information and Communication Technology (ICT) to enhance knowledge sharing between researchers and advisors. The associated research question is to what extent ICT supported a virtual Community of Practice and has been effective in counteracting fragmentation between research and advisory systems in terms of knowledge sharing between these two pillars of the Italian Agricultural Knowledge System (AKS). Design/Methodology/approach: The paper uses a mixed methods approach: a questionnaire submitted to the Community of Practice participants on their experiences, observation of interaction between Community of Practice participants and data on the use of the ICT platform. Findings: The ICT supported Community of Practice approach appears to improve knowledge sharing between researchers and advisors, and also draws in other actors of the broader Agricultural Knowledge and Innovation System in which the AKS is embedded. However, ICT based tools alone are not sufficient and need to be complemented with face-to-face (non-virtual) interactions. A clear theoretical implication of this study is that this is an iterative process in which virtual and non-virtual interaction mutually reinforce each other: ICT interaction spurs real life and face-to-face interaction, and ICT supports follow-up on real life face-to-face interaction. Practical Implications: Communities of Practice can be a useful tool for knowledge sharing between research and advisory systems, but should have a degree of flexibility in terms of the topics they address and should accommodate new members when appropriate. ICT is supportive, but should be complemented by real life meetings. Originality/Value: The paper connects recent frameworks of the use of Communities of Practice with literature on ICT in agriculture and adds insights on the contribution of combining virtual and non-virtual interaction in Communities of Practice aimed at knowledge sharing.

This study investigates how the relationship between farmers and buyers affects the adoption of sustainable agricultural practices (SAPs) in the vegetable sector in Chile. Specifically, we focus on the dyadic relationships between farmers and different types of buyers, including besides lead firms, intermediaries, and wholesalers, which have received little attention in the scientific literature. Our analysis focuses on formal and informal contracts as governance forms between farmers and buyers, and explores the correlation between contract provisions (e.g., quality, quantity, and the provision of services), relationship attributes (i.e., satisfaction, trust, and opportunism) and adoption of SAPs. We gathered survey data from 352 vegetable farmers in Chile and employed analysis of variance and logit modeling for our analysis. Our findings indicate that small‐scale farmers primarily engage with intermediaries using informal contracts, while medium‐scale farmers trade with wholesalers through spot markets, and large‐scale farmers with lead firms using formal contracts. We also found that farmers who traded through informal contracts, mainly with intermediaries, reported greater satisfaction in the farmer‐buyer relationship than farmers trading through formal contracts. However, farmers engaging in informal contracts were less likely to adopt SAPs than farmers trading through formal contracts. Our results suggest that the governance form (contracts or spot market) adopted for the relationship between farmers and buyers influences the adoption of SAPs, while the impact of relationship attributes on SAP adoption is less clear. A deeper understanding of buyers and their relationship with farmers is essential to enhance policies encouraging SAP adoption in regional and local fresh food supply chains.

The paper focuses on Agro-food waste valorization conceived as a long-term, complex socio-technical process involving several different actors belonging to multiple levels. Although this process is typically affected by a series of uncertainties, the convergence of stakeholders’ expectations proves to be a means to overcoming barriers, as it acts as the foundation of a shared agenda setting which formalizes the coordination efforts among the actors involved in an innovation process. Applying the strategic niche management (SNM) framework to the case of the Apulia Agro-Food Technology District (DARe), whose mission is to promote a bio-based industry for food-waste valorization, the paper proposes an operational tool capable of designing the strategy based on the entrepreneurs’ knowledge. The DARe aims to promote the technological innovation of agro-food firms located in the South of Italy. The results of a SWOT-SOR analysis led to the establishment of a twofold strategy aimed at (a) promoting the innovation of more active and dynamic firms, and (b) reducing the gap between “pioneer” and “laggard” firms, with the result of promoting integrated innovation throughout the entire district.
