- Abstract via online journal. 2 pages., Technological innovation is vital to economic growth and food security in sub-Saharan Africa where agricultural productivity has been stagnant for a long time. Extension services and learning from peer farmers are two common approaches to facilitate the diffusion of new technologies, but little is known about their relative effectiveness. Selection bias, whereby well-motivated training participants would perform better even without extension services, as well as knowledge spillovers, where non-participants can indirectly benefit from extension services, are among the major threats to causal inference. Using a unique sequential randomized experiment on agricultural training, this study attempts to meet the dual objectives of executing rigorous impact evaluation of extension services and subsequent spillovers on rice production in Cote d’Ivoire. Specifically, to reduce selection bias, we randomly assigned eligibility for training participation; and to satisfy the stable unit treatment value assumption, control-group farmers were initially restricted from exchanging information with treated-group farmers who had received rice management training. Once some positive impacts were confirmed, information exchange between the treated and control farmers was encouraged. We found that the initial performance gaps created by the randomized assignment disappeared over time, due presumably to social learning from peer farmers. A detailed analysis concerning the information network and peer effects provided suggestive evidence that there were information and technology spillovers from treated to control farmers after removing the information exchange restriction. Overall, our study demonstrates that information dissemination by farmers can be as effective in improving practices as the initial training provided by extension services.

- 22 pages, via online journal article, Purpose: Soil fertility is decreasing in many parts of Sub-Saharan Africa. To mitigate this trend, various agricultural technologies are available, but their uptake by farmers has been low. Perception of the problem, information exposure, and knowledge play a major role in adoption of technologies. This study assessed empirically the levels of perception, knowledge and information exposure among African farmers as an indicator for potential adoption of soil fertility technologies. Design/Methodology/approach: The study used survey data of more than 2,400 small-scale farmers selected through random sampling from Ghana, Kenya, Mali and Zambia. The survey investigated socio-economic factors, exposure to media, perception and knowledge of soil fertility and other information. Findings: Many farmers did not perceive soil fertility as a major challenge, except in Mali; farmers were hardly receiving information on soil fertility from professional agricultural sources, and they often lacked accurate knowledge about soil fertility technologies. Radio was by far the most used information source for farmers. Practical implications: The study has exposed the need for interventions to increase awareness, information exposure, and knowledge about soil fertility among farmers to strengthen the adoption of soil fertility technologies. It also calls for innovative ways of strengthening extension services through links with radio. Theoretical implications: The role of communication in the uptake of agricultural innovations is still under-researched, and hence this study exposes the need to investigate in-depth knowledge, perception levels, and quality and frequency of information exposure on various channels of soil fertility management. Originality: This is one of the few studies empirically measuring perception, information frequency on various channels, and knowledge of soil fertility among small-scale farmers in African countries.
