Open source software (OSS) has gained traction in various sectors globally, including agriculture. In Zambia’s Copperbelt, small-scale agricultural entrepreneurs are increasingly adopting OSS to enhance productivity and efficiency. The study employed a mixed-methods approach combining quantitative surveys with qualitative interviews to assess user satisfaction and technological integration among selected farmers. A notable trend identified was the significant improvement in data management systems (DMS) functionality, with over 70% of respondents reporting enhanced accuracy in crop yield records. Farmers also noted reduced costs associated with software maintenance and upgrades. OSS adoption has positively impacted the operational efficiency and financial sustainability of small-scale agricultural enterprises on the Copperbelt. Policy makers should encourage further OSS adoption through subsidies, training programmes, and partnerships with tech companies to support sustainable agriculture development.
