Rapid climatic and socio-economic changes challenge current agricultural R&D capacity. The necessary quantum leap in knowledge generation should build on the innovation capacity of farmers themselves. A novel citizen science methodology, triadic comparisons of technologies or tricot, was implemented in pilot studies in India, East Africa, and Central America. The methodology involves distributing a pool of agricultural technologies in different combinations of three to individual farmers who observe these technologies under farm conditions and compare their performance.
Smallholder farmers across the Global South increasingly need to adapt their farming activities to fast-paced changes, for example, in climate, policy and markets. In many places, public and private agricultural extension services support technological change through trainings and the dissemination of information. The effectiveness of extant ex-tension (advisory) methodologies is, however, challenged by the difficulty of reaching a large and growing clientele with highly diverse information needs.
Agricultural extension in the Global South can benefit greatly from the use of modern information and communication technologies (ICT). Yet, despite two decades of promising experiences, this potential is not fully realized. Here, it is reviewed the relevant research literature to inform future investments into agricultural information services that harness the full potential of digital media.The study describes a recently emerging innovation agenda that is, in part, a response to the eventualfailure of many new agro-advisory initiatives.
