With its rapid proliferation in the developing world, information and communication technology (ICT) has been accepted as an opportunity to assist disadvantaged people. Many projects have piloted ICT supporting rural communities in developing countries. Such rural communities are socially complex and infrastructurally weak environments that demand clear understanding of the social, economical, cultural and political preconditions when implementing ICT innovations. To provide a comprehensive overview of what kinds of ICT intervention and research contributions have been achieved, a systematic mapping study (SMS) was carried out. This work presents the state-of-the-art based on related journal and conference papers published between 2006-2014. The review indicates that ICT supporting farmers has gained attention over the past few years with a growing number of contributions. However, the field is still in a consolidating phase. Theoretical concepts are sparse, so it is difficult to generalize and transfer the findings. Specifically, there is limited research in IT design and development process; user-interface design for illiterate people; and user and community involvement in the design process.
