Social Networks like Facebook, Twitter, YouTube and WhatsApp are now becoming very popular tools that are used for sharing the latest and important farming based information in different part of India. These tools are now widely used by Agricultural Extension and Advisory services to interact with the farmers for exchanging agricultural related information in India. The most influential farmers in a network can disseminate the information to the less central farmers of the network. The extension functionaries that promote the agricultural innovation will share the information with the most central members which in turn will share it with maximum number of the members of a social network. Social Network Analysis (SNA) acts as an efficient analytical tool that helps us to understand the relationship between farmer stakeholders and the importance of a farmer's position in the entire network. In this paper, a structural analysis of the Social Network is performed over two datasets, namely, Facebook-like dataset and Twitter Lists dataset. Here, we have studied the importance of individual nodes in the network through various centrality measures. SNA properties like centralities are used to represent the most central nodes that can act as a good influence spreader in the network. In this paper, initially the k-core decomposition method is used to find a set of influential nodes among all the nodes in the network. It is done to reduce the computational time. Our simulation shows that the nodes with higher Page Rank centrality can activate more members in a network as compared to other centrality measures. For Information diffusion, we have used Linear Threshold (LT) Model to understand the influence spread of the central farmers in the network.

Notes:
8 pages., IAALD XIIIth World Congress., via IAALD website., Governments have been largely responsible for research and the provision of extension services in Nigeria. The emphasis has been on the transfer of technology, paying little attention to farmer development and communication needs. Recently, the high output of agricultural research has led to a large pool of new agricultural technologies, which are yet to be disseminated to farmers, particularly those in the core rural areas. Therefore this study examined development and information need of the resource poor and the strategy adopted to meet these needs, using „town crier‟ as a case study. The study identified 2 states in south west, Nigeria, based on literature/past studies, where this concept has been adopted. A focused group discussion technique and interview schedule was adopted for data collection. The study identified 141 „town criers‟ across the study areas through the help of key informants. Results shown all Town Criers are male, average age of 55.54 years and all have postsecondary education. Town Crier primarily source of information is from the traditional-head. Main information disseminated by the Town Crier bothers on security of the town and community development and projects. The study concluded that this channel rarely meets the information need of the people, as the study revealed that only 20% of such information meets these needs. Past studies have documented that information/communication channels in Nigeria such as extension institution has collapse, there is no effective communication channels in the country again. The small number of extension officers that exists, only congregate at the urban towns, leaving behind those at the rural areas. Thus, the use of town criers in this regards can be used effectively to fill this gap and can also be trained on basic extension work.

8 pages., Fifth IEEE International Conference on Wireless, Mobile, and Ubiquitous Technology in Education., via online journal., This paper presents an innovative application of wireless, mobile and ubiquitous technologies to support informal and collaborative learning in Kenyan rural farming communities. Such an approach is achieved by the development of a knowledge management system (KMS) integrated with existing local community communication channels, together with experimental knowledge management (KM) initiatives employing the VeSeL (Village e-Science for Life) distributed resource kits (DRKs). The initiatives support illiterate and semi-literate farming community groups, in learning new agriculture practices, and also enable the use of advanced digital technology to improve their agricultural practices and literacy levels. Results of a recent field trip to Kenya are presented and an application sketch is developed. The process of applying wireless and Internet technologies for the education of local farming communities, using irrigation and water management as the application, concludes the paper.
