9 pages, This study investigates how communication channels to exchange agricultural information were chosen. Specifically, it identifies the communication channels used by farmers in Tanzania and determines the factors influencing the choice of communication channels for exchanging agricultural information. The study employs a meta-analysis review methodology in identifying, evaluating and interpreting studies relevant to the topic of interest. The results indicate that radio, mobile phones, television, fellow farmers, agricultural extension agents and newspapers were the commonly used communication channels for transferring agricultural information. Moreover, the channels’ influence, availability, affordability, communication network coverage, and the resources and facilities needed to use a particular communication channel were found to influence the choice of channels. It is concluded that understanding the audience, the characteristics surrounding messages and choosing appropriate communication channels are important for enhancing access to agricultural information. It is recommended that agricultural information providers should understand the factors surrounding communication channels before disseminating agricultural information
11 pages., In 2016, a study was conducted in Tanzania to assess the impact of radio and SMS in scaling-up smallholder participation in legume-based sustainable agricultural intensification (SAI) practices and technologies. The study aimed to answer the following research questions: (i) does participation in the campaign enhance farmers’ knowledge of legume-based sustainable agricultural intensification practices and technologies? (ii) what is the impact of the campaign on the adoption of legume-based sustainable agricultural intensification practices and technologies?; (iii) does exposure to multiple ICT-enabled channels result in larger gains (in terms of knowledge and adoption) than exposure to only one channel? (iv) is it more cost-effective to use radio or SMS alone or use them in combination? The results show that both awareness and adoption are boosted if SMS supports radio campaigns. However, radio alone is the most cost-effective approach. Each dollar spent on the radio campaign results in 2.1 farmers that have adopted at least one new practice, compared with 0.5 farmers for SMS and 0.4 farmers for radio and SMS combined. Other factors were also important in facilitating uptake of legume-based SAI practices, such as gender, age, education and land size, but were not statistically significant when rated against the communication channels used.
