Design and evaluate a peer-led agricultural extension program for smallholder farmers

Thesis Abstract

Smallholder farmers in developing regions often face significant barriers to accessing timely, relevant, and effective agricultural advice, which hampers productivity and sustainable development. Traditional extension approaches, typically delivered by government agencies or NGOs, have shown limitations in reach and community acceptance, necessitating innovative strategies that leverage local social structures and peer influence. This study aims to design, implement, and evaluate a peer-led agricultural extension program tailored for smallholder farmers to enhance their adoption of improved farming practices and increase productivity. Specific objectives include identifying key peer role models within smallholder communities, developing a participatory extension curriculum, training peer extension agents, and assessing the program’s impact on farmers’ knowledge, practices, and yields. Employing a mixed-methods research design, the study integrated qualitative and quantitative approaches to provide a comprehensive evaluation. The quantitative component involved a quasi-experimental design with a sample of 200 smallholder farmers, randomly assigned to treatment and control groups, selected through stratified random sampling from two comparable districts. Data collection instruments comprised structured questionnaires, focus group discussion guides, and field observation checklists. The questionnaires measured farmers’ knowledge, attitude, and practices (KAP), while yield data were obtained through direct measurement of crop outputs. To ensure instrument validity and reliability, pre-testing was conducted with a subset of 30 farmers, and Cronbach’s alpha coefficients exceeded 0.8 for all scales. Qualitative data from focus groups and interviews were analyzed thematically to contextualize quantitative findings. Quantitative data were analyzed using descriptive statistics, paired t-tests, and regression analysis, specifically multiple linear regression, to determine the effect of the program on key outcome variables. The anticipated findings suggest that the peer-led extension program will significantly improve farmers’ knowledge and adoption of recommended practices, resulting in increased crop yields—expected to rise by an average of 15-20% among participating farmers. Regression analysis is projected to reveal that participation in the peer-led program is a strong predictor of positive behavioral change and yield improvement, controlling for socio-economic and demographic factors. Qualitative insights are expected to highlight the importance of peer trust, social cohesion, and community participation in sustaining behavioral change, aligning with social learning theory and diffusion of innovations theory, which underpin the program’s conceptual framework. This research contributes novel empirical evidence on the effectiveness of peer-led extension models in smallholder contexts, addressing limitations of traditional top-down approaches. It advances theoretical understanding by integrating social learning and diffusion theories within an agricultural extension framework and demonstrates the potential of community-based participatory methods in fostering sustainable agricultural development. The findings provide practical insights for policymakers and extension agencies seeking cost-effective, participatory approaches that leverage local social networks. The study concludes that peer-led extension models hold significant promise for improving smallholder farmer productivity and resilience. Recommendations include scaling up peer-led training initiatives, fostering continuous peer mentorship, integrating local knowledge systems, and strengthening institutional support for peer agents. Future research should explore long-term impacts, adaptation to diverse crop systems, and the integration of digital communication tools to enhance peer learning networks. Overall, this study underscores the value of community-driven, participatory extension strategies as a sustainable pathway to agricultural development.
