From our perspective: developing printed extension materials with cocoa farmers in Ghana

Farmers' lack of access to technical information constitutes a major obstacle to improving cocoa productivity in West and Central Africa. Recent debates on cocoa extension pay little attention to the potentially important role of printed extension materials for promoting cocoa integrated crop and pest management (ICPM) and encouraging farmer experimentation. A key issue concerns how to design such materials to meet farmers' needs. Typically, printed agricultural extension materials are developed by technical experts with little input from farmers, the end users. Materials developed in this way are often incomprehensible or confusing to farmers as they tend to contain too much information and use culturally inappropriate symbols and complex language. This paper describes a process involving Ghanaian cocoa farmers, communications and extension specialists to develop an illustrated booklet on cocoa integrated crop and pest management. The case study shows that farmers can make significant contributions to designing printed extension materials by bringing their own perspectives to the sequencing and design of the materials, highlighting details and showing illustrators the most effective ways to convey messages in a non-written way (using body language, colour etc.). As a result of farmers' involvement, the illustrations in the booklet are presented in a story context and sequence, and use a cause and effect approach to communicating ideas. Farmers' input also ensured that the illustrations provide a holistic presentation of cocoa farming by highlighting the linkage between application of technologies and improved household welfare. The paper concludes by offering guidelines on best practices for involving farmers in extension material development.

Volunteer farmer-trainer motivations in East Africa: practical implications for enhancing farmer-to-farmer extension

Farmer-to-farmer extension (FFE) has received considerable interest in developing countries due to a decline in government extension services. There are, however, questions as to how FFE can be improved to enhance effectiveness and sustainability of the approach. One area that may hold the key is to understand volunteer farmer-trainer (VFT) motivations. Informal and formal interviews were held with VFTs in a smallholder dairy development project in Kenya, Uganda and Rwanda. Data were collected on the reasons why VFTs became trainers and why they continue to train. Findings of the study showed that VFTs were motivated by a combination of intrinsic and extrinsic factors. These factors are not static; they change over time. Gaining knowledge and skills as well as altruism were found to be the most important motivating factors for becoming trainers in the three countries. However, a few years after becoming trainers, income earned from selling inputs and specialized services associated with training was an important motivating factor to VFTs in Kenya. In Uganda gaining knowledge and skills remained the most important whereas in Rwanda, a new motivation, increased demand for training, was the most important reason for continuing to train. These findings point to the fact that the general reasons that motivate VFTs irrespective of context are similar; however, the importance attached to motivations is context specific. These motivations can provide insights into which incentives can be enhanced to improve effectiveness and sustainability of FFE.
