Book chapter 15The major purpose of this chapter is to explore the options of Information and Communication Technologies (ICTs) to complement conventional agricultural extension services in Tanzania. Group discussions and meetings were conducted to investigate the role of ICTs in extension services delivery using CATWOE framework of Soft Systems Methodology. The findings of the study reveal that the use of SSM helped the researchers to understand easily the problematic areas of the current situation of agricultural extension services. In addition, it was easy to plan feasible actions to be taken to improve the situation. The framework for the conceptual model towards improving the agricultural extension services in Kilosa District of Tanzania was developed. These results have been used in the development of an ICT-based system (Web- and Mobile-Based Farmers’ Advisory Information Systems) to supplement the conventional agricultural extension system. The roadmap developed as the implementation plan for this research can be used in any e-Government project. The need to improve the way agricultural extension is done in Tanzania through integration of relevant and affordable ICTs is well researched. This book chapter presents how this can be done using SSM approach in an action and participatory research. This is the first presentation of SSM intervention in agricultural informatics in Tanzania. The approach used in this study can be adopted by researchers doing any e-Government research.
