Improved storage technology and post-harvest loss reduction among smallholder farmers: the role of Sasakawa Africa Association in Kano, Jigawa and Katsina States, Nigeria

Abstract

Post-harvest losses pose a significant threat to food security among smallholder farmers in northern Nigeria. This study assessed the impact of improved storage technologies introduced by the Sasakawa Africa Association (SAA) on post-harvest loss reduction in Kano, Jigawa, and Katsina States. A mixed-methods approach was employed, combining structured questionnaires administered to 360 farmers with key informant interviews and focus group discussions. Descriptive and inferential statistics, including adoption rates and paired t-tests, were used to analyse quantitative data, while qualitative data were thematically analysed. Findings reveal that hermetic bags, metal silos, and improved cribs were the primary technologies promoted, with adoption levels highest for hermetic bags (35.84%). Post-harvest losses decreased substantially after adoption, with average losses dropping from 23.4% to 9.2%, and pest-related losses reduced by 68%. Farmers reported positive perceptions regarding effectiveness, ease of use, and grain quality improvement. However, high cost, limited credit access, and low awareness were identified as major constraints to adoption. The study concludes that SAA interventions significantly enhance food security and household resilience, but sustainability depends on addressing financial, institutional, and awareness-related barriers. Recommendations include subsidizing storage technologies, improving access to credit, strengthening extension services, promoting community storage systems, and increasing farmer awareness of mycotoxin risks.
