Logistics and Distribution Management in the Yam Value Chain in Taraba State

Yam is one of Nigeria's most important staple crops, and Taraba State, in the North East geopolitical zone, is a significant producing area that supplies yam to markets across the country. Despite strong production volumes, logistics and distribution inefficiencies along the yam value chain in Taraba State result in high post-harvest losses, elevated transaction costs, and reduced producer income. This study examines logistics and distribution management practices in the yam value chain in Taraba State and identifies priority areas for operational improvement. A sample comprising 50 yam farmers, 25 assemblers, and 20 long-distance wholesalers was selected from three local government areas using purposive and snowball sampling methods. Supply chain mapping, time-motion studies of distribution operations, and cost structure analysis were conducted using structured interviews and observational data. Results reveal that handling and loading operations cause physical damage to 18 to 24 percent of tubers before transport, primarily due to absence of packaging standards. Transportation from production areas to Jalingo and inter-state markets adds an average of 35 percent to farm gate prices, with road quality being the primary cost driver. Cold storage is virtually nonexistent in the value chain, contributing to a post-transport loss rate of 12 percent. The study recommends standardisation of yam packaging using padded crates, investment in feeder road upgrades between major producing communities and trunk roads, and the establishment of yam aggregation centres as logistics hubs in Taraba State.
