Assessing Barriers to Supply Chain Resilience: A Case Study of Perishable Foods Among Lusaka Traders

Despite increasing global attention to supply chain disruptions, limited research has focused specifically on the barriers to resilience in perishable food supply chains (PFSCs) in Sub-Saharan Africa. In Zambia, where informal markets play a central role in food distribution, the lack of systematic studies on PFSC resilience presents a significant gap. This study aims to assess the key barriers undermining PFSC resilience in Lusaka, the country’s capital, and propose actionable strategies for improvement. Using a mixed-methods approach, data were collected through structured questionnaires administered to 410 perishable food traders and in-depth interviews with 10 stakeholders across key points in the food supply chain. Findings revealed that unpredictable market demand, cited by 31.2% of respondents, was the most significant barrier, followed by lack of financial resources (16.6%) and poor transportation infrastructure (15.9%). Climate change and weather variability, alongside inadequate storage facilities, further exacerbated challenges. Traders implemented strategies such as collaboration, investment in improved storage, and adoption of monitoring tools; however, their effectiveness was constrained by limited financial capacity and technical expertise. The study proposes a multi-faceted resilience framework grounded in the Supply Chain Resilience Framework (SCRF), emphasizing infrastructure development, technology adoption, and stakeholder capacity building. Key policy recommendations include targeted government investment, digital tool promotion, and the formation of public-private partnerships to facilitate sustainable PFSC operations. Addressing these barriers is critical to reducing food loss, enhancing food security, and supporting Zambia’s broader economic development goals.
