Assessing Mobile App Effectiveness in Enhancing Smallholder Farmers' Adoption of Sustainable Practices

Thesis Abstract

This study investigates the effectiveness of a mobile application designed to promote the adoption of sustainable agricultural practices among smallholder farmers in the region, addressing the persistent challenge of limited access to agricultural extension services and information that hinders sustainable farming transitions. The research aims to evaluate whether the use of the mobile app significantly influences farmers’ knowledge, attitudes, and practices related to sustainability, and to identify the factors mediating or moderating this relationship. Specific objectives include assessing the extent of app usage among smallholders, measuring changes in sustainable practice adoption attributable to the app, and exploring farmers’ perceptions of its usability and benefits. Employing a mixed-methods research design, the study combines quantitative survey methods with qualitative interviews to provide comprehensive insights. The quantitative component involves a stratified random sample of 450 smallholder farmers from three districts, selected based on demography, farm size, and prior mobile phone usage. Data collection instruments include a structured questionnaire measuring variables such as awareness of sustainable practices, app usage frequency, and behavioral change, alongside app usage logs for objective tracking. Qualitative data are gathered through semi-structured interviews with 30 farmers and key informants, to contextualize the quantitative findings and explore perceptions of the mobile application’s usability, relevance, and impact. Data analysis employs descriptive statistics to outline demographic and usage patterns, while inferential techniques such as multiple regression analysis test the relationship between app usage and adoption levels of sustainable practices. The Technology Acceptance Model (TAM) and Diffusion of Innovations theory underpin the theoretical framework guiding the study, providing lenses for understanding technology adoption behavior among smallholders. Thematic analysis of qualitative data highlights farmers’ perceptions and barriers to utilization, enriching the interpretation of quantitative results. Expected findings indicate a positive correlation between mobile app usage and increased adoption of sustainable practices, with factors like app usability, perceived usefulness, and extension support significantly mediating this relationship. The study anticipates discovering that farmers with higher literacy levels and prior mobile experience demonstrate more significant behavioral change, highlighting digital divide concerns. It is also expected that perceived barriers such as network connectivity and digital literacy may impede full engagement with the app. The research contributes to knowledge by empirically validating the role of ICT interventions in agricultural extension, specifically elucidating the mechanisms through which mobile apps influence sustainable farming behaviors among smallholders. It advances theoretical understanding by integrating TAM and Diffusion of Innovations theories within agricultural extension contexts, offering a model for scalable digital interventions. Concluding, the study emphasizes the potential of mobile applications as cost-effective, scalable tools for enhancing sustainable agriculture adoption, provided contextual barriers are addressed. Recommendations include strengthening digital literacy programs, improving app content relevance, and fostering institutional support to ensure sustained engagement. The study advocates for policymakers, extension service providers, and developers to prioritize user-centered design and contextual adaptation in future digital agricultural interventions. Suggestions for further research include longitudinal studies to evaluate long-term impacts and comparative studies across different agricultural regions to assess transferability.
