Abstract	La comunicación del conocimiento científico es parte fundamental del progreso de la ciencia y vital para la sociedad moderna. Así, las conferencias y congresos científicos son espacios cruciales para estos procesos de comunicación. Esta investigación tiene como objetivo analizar la comunicación de trabajos científicos en un congreso agrícola; de tal forma que se añade conocimiento a la literatura en tres vertientes: uso de datos, aplicación metodológica y evidencia empírica. Para hacer esto, analizamos 316 títulos de ponencias presentadas a lo largo de cinco años. Usamos dos enfoques metodológicos: data-mining y análisis de redes sociales (ARS). Los resultados muestran que en los 316 títulos se han utilizado 1,093 términos diferentes, siguiendo una distribución power-law. A través de una red de bi-gramas, se encontró que estos términos están unidos por 1,847 relaciones dirigidas. Además, con el ARS se identificaron las palabras más importantes según distintos indicadores. Se concluye que la información existente en los archivos de congresos científicos es rica en contenido y puede ser útil para encontrar brechas de conocimiento. Además, los enfoques utilizados se complementan entre sí. Este artículo proporciona evidencia técnica y empírica sobre el campo del network mining.

Abstract	Purpose – This paper aims to contribute to deepening insights on social media in agricultural research by presenting a case study on how a research and education centre in Mexico connected, communicated, and interacted in a research and education community on Twitter. Design/methodology/approach – By using a Social Network Analysis (SNA) approach, 1585 tweets were analysed. The data was gathered using NodeXL. Afterwards, SNA was performed through the igraph R package. Findings – The dynamic of virtual interaction around an agricultural research and education centre shows that different roles are needed to connect and foster the interaction on Twitter, as well as to spread information broader. While some accounts are functioning as creators of information, others act as consumers and diffusers of it, and a few more accounts play both roles. Practical Implications – To increase the size and strengthen the interaction of a network on Twitter, it is advisable to have the support of other accounts and to promote its use among potential users. This requires capabilities to develop a social media strategy and pro-actively engage new followers. Theoretical Implications – Through a SNA approach, it is possible to understand better the functions of weak and strong ties in virtual settings, i.e. the former to extend the network, and the latter to strengthen it. These ties can enhance information dissemination and enable exchanges on social media. Originality/value – This paper applies SNA as a theoretical and methodological framework to demonstrate that the interactions among users are different when a whole network is analysed, and when it is divided into the mentions and retweets networks. By doing this, hidden patterns are revealed.

Abstract	The objective of this study was to examine social networks in dairy value chains (DVCs) in Kenya and understand how DVC actors’ power relationships and trust influence their behaviour regarding milk quality. We conducted a stakeholder analysis using the Net-Map tool in Laikipia, Nakuru and Nyandarua counties in Kenya. VisuaLyzer software was used to analyse the social networks. Thematic content analysis of the discussions, recorded during the mapping exercise, was undertaken using ATLAS.ti. Formal DVC had more actors and dense social networks characterised by vertical and horizontal integration, high levels of power asymmetries between actors, limited trust and short-term contractual arrangements. Informal DVC was characterised by fewer actors and less dense social networks, low levels of power asymmetries between actors and a high level of trust due to the existence of reciprocal personal relationships. Milk was perceived to be of higher quality in the formal value chain reflecting top-down enforcement of milk standards, bottom-up collective action, power asymmetries and contractual relationships. Poor milk quality management in the informal DVC underscores the need for powerful actors, e.g. regulatory agencies, and buyers such as processors, to influence other DVC actors’ behavioural change. Understanding and leveraging DVC social networks and actors’ power and addressing power asymmetries and enhancing trust between actors will increase compliance with milk quality standards. There is an urgent imperative to design policies and interventions which empower DVC actors, by providing economic incentives, enhancing their skills and knowledge and their access to infrastructure which facilitates milk quality improvement.

Abstract	El objetivo de esta investigación fue analizar cómo está estructurada la red de actores que hablan de productos orgánicos en Twitter y, a través de la identificación de actores clave, conocer la influencia que ejercen dentro de las redes; al hacerlo, desarrollamos ideas significativas que permitan a los usuarios de medios sociales mejorar su interacción y posición dentro de la red. Se buscaron y descargaron los datos de los términos #organico(a) y #organicos(as) por un periodo de seis meses. Para su procesamiento y estudio, se utilizó el enfoque teórico y metodológico del análisis de redes sociales (ARS). La red general se formó por 14,329 tweets únicos, publicados por 6,667 usuarios, configurando una red de 6,521 vínculos directos. Para entender con mayor detalle las interacciones, se segmentó la red con base en dos tipos de relaciones: (1) retweets y (2) menciones o respuestas, ambas redes mostraron estructuras diferentes. Se encontró que el conjunto de relaciones que estructuran la red social está asociado a productos, países y temas, así como a diversos actores clave. Además, la expresión de los orgánicos en Twitter sigue de cerca la visión general de considerarse benéficos para la salud y el medio ambiente.

Abstract	Scaling up innovations has emerged as an important requirement to address the challenges faced by the agricultural sector. However, current interpretations of scaling up are often too simplistic, and there is a need to integrate perspectives that capture the complexity involved in scaling up an innovation. In this context, we believe that the structural-functional approach of the innovation system can contribute to the understanding of the underlying factors that enable the successful introduction and scaling up of an innovation. Our objective is to improve the understanding of how system functions and their interactions influence the introduction and scaling up of an innovation. We provide a case study that illustrates the development and scaling up of MD-2 pineapple in the world and in Mexico. For the integration and analysis of the information, the event history technique, applied in various studies on innovation systems, was used. This technique consists of the identification, classification, and analysis of events according to the system functions. The success of the expansion of MD-2 pineapple in the international market can be explained, to a large extent, by the fulfilment of all the system functions, which interacted positively and reinforced each other, resulting in great dynamism in the demand for this fruit. This functional pattern created entry points for other countries, once the MD-2 genotype was in the public domain and the market had appreciated its commercial potential. With these conditions in place, Mexico was also incorporated into this varietal innovation. Thus, market formation was the initial push for Mexican pineapple farmers to begin producing the MD-2 pineapple. Its exploitation involved the development of various technical changes and market-oriented activities. These changes were made possible by the fulfilment and interaction of system functions. The findings of this study contribute greatly to our understanding of how an innovation develops in the context of a developing country. With the mapping of the system functions, it was possible to: (i) reconstructing innovation processes from their origin to their scaling up; (ii) understanding innovation as a process, path-dependent and influenced by multiple dimensions. Understanding each of the functions of innovation system provides information on those processes occurring within the system that require special attention. This information can be used by the scientific community together with decision and policy makers to develop more appropriate intervention strategies based on the functions that have a ripple effect on innovation.

Abstract	Understanding how to improve the accessibility and timely dissemination of weather and market information can help farmers adapt their management to climate change impacts. Our objective is to use Social Network Analysis (SNA) as a tool to identify potential opportunities for improving weather and market advisory dissemination to rural communities and to explore the relationship between farmers’ access to information and yield and selling price. As a case study, we applied SNA to 313 farmers in Bangladesh to analyze weather and market information networks and farmers' friendship networks as a potential proxy for information exchange. Farmer access to information, dominant sources of information and potential speed of information transfer were key criteria for our analysis. Our results indicate that weather and market information networks in coastal Bangladesh depended on certain key sources of information, while the friendship network was decentralized and interconnected, with few isolated farmers. We showed that farmers networks are significantly correlated with several socio-agro-economic variables; however, there was little indication of a relationship between information access and yield and selling price. We conclude that a mixed approach of targeting central actors and broadcasting information to farmers may be a suitable strategy to reach a maximum number of farmers as well as the most isolated farmers. Our study highlights that SNA can be a promising tool to reveal hidden structures of information flows in farmer communities and provide valuable insights for developing information dissemination strategies that reach even the most remote and underserved farmers.

Abstract	In this data article, we provide a dataset of 8,982,694 Twitter posts around the coronavirus health global crisis. The data were collected through the Twitter REST API search. We used the rtweet R package to download raw data. The term searched was "Coronavirus" which included the word itself and its hashtag version. We collected the data over 23 days, from January 21 to February 12, 2020. The dataset is multilingual, prevailing English, Spanish, and Portuguese. We include a new variable created from other four variables; it is called "type" of tweets, which is useful for showing the diversity of tweets and the dynamics of users on Twitter. The dataset comprises seven databases which can be analysed separately. On the other hand, they can be crossed to set other researches, among them, trends and relevance of different topics, types of tweets, the embeddedness of users and their profiles, the retweets dynamics, hashtag analysis, as well as to perform social network analysis. This dataset can attract the attention of researchers related to different fields on knowledge, such as data science, social science, network science, health informatics, tourism, infodemiology, and others.

Abstract	There is promising evidence that public food procurement from family farming (PFPF) can serve as a powerful policy instrument in transitions towards more sustainable food systems. Despite the evidence around PFPF, there is lack of systemic and actor-oriented approaches analysing the relational and interactional dynamics among the multiple and diverse sets of actors in PFPF programs. In this paper, we address this gap by presenting an integrative framework that brings together food systems research, innovation studies and social network analysis, to assess the role of actor networks in PFPF. To illustrate the usefulness of the framework, we present the case of public procurement from family farming in Uruguay. We show how the framework has potential to: highlight the composition and diversity of networks of actors in PFPF; unravel individual and network barriers faced by actors in food systems; and, identify how interactions and (intermediary and brokerage) roles of network actors stimulate innovation or block the changes that are needed for PFPF to catalyse the transition towards sustainable food systems.

Abstract	Home gardens are often conceived as a panacea to contribute to the problem of food insecurity in poor rural and urban households. However, systematic reviews indicate weak evidence of significant impacts on families. This way, there has been an intense discussion about their effectiveness. This research aims to generate knowledge about the relevance of assuming food production in home gardens as an alternative to the home consumption. Two questions drive this paper: what number of home gardens, supported by three different government programs, persists? Moreover, what factors explain their permanence? Our sample constituted 261 beneficiaries, and the collection of data was through face-to-face field surveys and in situ visits to the vegetable garden granted. We show that less than 7.5% of gardens remain in right conditions after two years of establishment. The pleasure and need to produce, family involvement, urban/rural location, and the technology provided are determining factors for permanence. The results support the argument that the high rate of home gardens that fail is related to the primacy of politics in considering the problem of food security as a “lack of assets” to produce. Thus, this suggests that there is a weak link between the problem, policies, and the politics.
