12 pages., Purpose
Pervasive use of poor quality seed remains an important reason for low yields throughout the developing world. We explore ways to increase the quality of the local stock of seed tubers among a sample of Ugandan potato farmers.
Design/methodology/approach: Using videos, we provide agricultural extension information on (i) how to select the best seed tubers and (ii) how to properly handle and store seed tubers until the next planting season. The relative effectiveness of the information interventions is tested using an individually randomized controlled trial where we model spillovers using a randomization-based framework for estimating causal effects under interference between units.
Findings: Especially the video on seed selection translated into increased awareness and adoption of recommended practices, increased probability of using improved inputs, as well as higher consumption.
Practical implications: Interventions aimed at improving seed quality are important in the absence of access to high-quality seed. Video messages are becoming increasingly useful as a complementary tool in agricultural extension.
Theoretical implications: Randomization-based inference can be used to take into account spillover effects in the analysis rather than the design phase of an experiment.
Originality/value: This is the first study to address seed quality of potato tubers in a real-world setting using videos.
Suggests that market oriented arrangements (i.e., privatized extension and research, output-financing) are probably less suitable than other institutional arrangements when the aim is to support experiential learning and interactive design towards sustainable agriculture.
21 Pages, Purpose: The article examines the implementation and effects of the model farmer-based approach of farmer-to-farmer extension delivery that is in use in Ethiopia.
Methodology: The study used mixed methods, combining focus group discussions, key informant interviews, and a household survey.
Findings: The model farmer approach has increased extension coverage, improved the possibility for information and technology dissemination, and enabled the inclusion of virtually all farming households in extension and advisory networks. Simultaneously, the approach has become a mechanism for the top-down control of farmers, for the identification and favouritism of better-off farmers, and those with political commitments.
Practical implications: The findings show that there is a need to critically reflect on who model farmers are, how they are selected, what their historical and current roles and impact have been, as well as follower farmers’ feedback on the approach in order to avoid perpetuating the misuse of the approach.
Theoretical implications: The article argues that the Ethiopian context that rewards rapid increase in production and productivity, modernisation of agriculture, competitive commercialisation, and a context that allows the continued entanglement of extension delivery with politics have enabled such misuse of the approach to proliferate. The article questions the extent of applicability of the core farmer-to-farmer extension principles that relate to social ties, reciprocity, collaboration, and minimal social hierarchies in such a context.
Originality/value: The study generates important insights about the effects of model farmer-based extension approach, its political dimensions, and the importance of context for successful farmer-to-farmer extension.
