    Mexico has optimal conditions for the cultivation of natural rubber but imports more than 80 % of its consumption. The model of development suppliers through Innovation Management Agencies (agi, for their acronym in Spanish) was implemented to improve this situation. This work analyzed the achievements of technical assistance services provided by two agi to two rubber agro-industries (ai) and their suppliers located in the Papaloapan River Basin, Mexico. From 2011 to the beginning of 2014, the Agencies generated reports and databases about technical, productive, organizational and commercial parameters of both rubber producers and agro-industries. With this information, global databases were constructed to analyze changes in production, supply, and innovation adoption. The results show that the intervention of the Agencies was relevant and effective in improving production and post-harvest parameters. The production of coagulated rubber also increased as well as the availability of raw material to the agro-industries. Moreover, production costs were able to be reduced, and the quality of the rubber was improved. However, the fall in rubber prices at the end of 2013 caused setbacks in the adoption of innovations and the agriculture-industry integration, showing the fragility of supplier development, as well as of the ai involved serving as lead and trailblazer companies in their suppliers' networks.

    Análisis de redes en twitter para la inserción en comunidades : El caso de un producto agroindustrial
    Aguilar-Gallegos, Norman ; Valdés-López, Armando ; Muñoz-Rodríguez, Manrrubio ; Martínez-González, Enrique Genaro ; Santoyo-Cortés, Horacio ; Aguilar-Ávila, Jorge - \ 2019
    Interciencia 44 (2019)2. - ISSN 0378-1844 - p. 75 - 81.

    The hashtags and relevant content in Twitter, related to the agroindustrial product mezcal were analysed, and the so-called ‘influencers’ were also identified. For doing this, 57.362 tweets were extracted and stored; three networks were built: users-hashtags, retweets, and mentions, which were studied by using social network analysis (SNA). The application of the SNA allowed revealing certain kind of hidden patterns within the social media complex relationships, which can be useful for designing strategies aimed at positioning actors and spread information. The results allow stating that in order to get inserted in the social network, the following should be considered: the use of combined hashtags, the message content kind, including pictures attached, and mentioning the most influential accounts who are embedded in already formed communities.

    Information networks that generate economic value: A study on clusters of adopters of new or improved technologies and practices among oil palm growers in Mexico

    The area under cultivation of oil palm has undergone considerable growth in Mexico, but yields are far below their potential. This is related to the low rate of adoption of new or improved technologies and practices in areas such as plantation management and farm administration. This study determines the factors that have an influence on adoption of new or improved technologies and practices and their relationship with the generation of economic value of oil palm. A cluster analysis of 33 key new or improved technologies and practices adopted by 104 growers was performed, and the main adoption categories and the variables influencing adoption are described. The results indicate that three clusters of growers can be discerned that differ in terms of their levels of adoption. The highest level of adoption of new or improved technologies and practices is related to higher yields and vice versa. The new or improved technologies and practices that differentiate the cluster of the advanced adopters from the cluster of the basic adopters are those related to plantation health, grower associations and production unit management. The cluster of the intermediate adopters is outstanding for their levels of adoption of new or improved technologies and practices in the aspects of plant nutrition, harvest, and genetics and reproduction. The advanced adopters set up better links for getting information, generally fromtheir extensionists. The three clusters each exhibit a great degree of homophily, indicating little information flow between the different clusters of growers, while these can learn from each other. These results make it evident that better articulation among different clusters of growers and other actors should be encouraged, and that diversified and tailor-made extension strategies should be designed to optimally support different clusters of growers.
