Assessing the impact of localized cold-chain systems on post-harvest loss reduction: a case study of Rubavu district, Rwanda

This study assessed the impact of localized cold-chain systems on post-harvest loss reduction among horticultural farmers in Rubavu District, Rwanda. A mixed-methods approach was employed, combining quantitative data from 120 respondents with qualitative insights from key stakeholders. Descriptive statistics and correlation analysis were used to examine the magnitude and determinants of post-harvest losses, as well as the relationship between cold-chain access and household income. The findings revealed that post-harvest losses were significantly high, averaging 49.5%, largely due to limited access to cold-chain facilities, poor transport conditions, and long market distances. Only 14.2% of farmers had access to cold storage, highlighting a critical infrastructure gap. The results further showed that cold-chain access significantly reduced losses and improved household income, while poor logistics and infrastructure increased spoilage and reduced earnings. Despite these benefits, adoption of cold-chain technologies was constrained by high costs, unreliable energy supply, inadequate infrastructure, and limited technical knowledge. The study concluded that localized cold-chain systems were essential for improving supply chain efficiency, reducing losses, and enhancing farmer livelihoods. It recommended increased investment in cold-chain infrastructure, improved rural transport and energy systems, financial support mechanisms, and capacity-building initiatives.
