The document analyzes 60 farmer advisory services in Africa that use ICT. It divides the projects into 4 categories based on the technology used: voice, radio, mobile phones, and e-learning. The most common technologies were internet, radio, and mobile phones. The projects varied in duration, scale, and type of organization implementing them. SMS services were popular but had limitations. Voice and video solutions provided benefits but also had costs. The most successful SMS service was Esoko, while Infonet-Biovision used pictures to overcome constraints of text. Barriers to scaling up the services included attracting private investment and developing appropriate technologies for local contexts.
