An integrated analysis of tomato supply networks in Nigeria to improve efficiency and quality
The fragmented nature of production, transport, marketing and sales, causes inefficiencies, high costs and low quality in the Nigerian tomato supply network. This study aimed to understand the functioning of fresh tomato supply networks in Nigeria, identify existing gaps in technical capacity and determine effective strategies for interventions to improve quality management. This study involved initial scoping activities to understand the status quo of the tomato supply chain from the leading tomato producing regions in the north and south-west. after scoping, validation workshops were conducted applying a living lab participatory research method. Stakeholders mapped out perceptions of their value chain, identifying loss hotspots, monetary and information flows as well as bottlenecks in the chain. The stakeholders proposed potential solutions that were implemented in 2 pilot projects: transportation of tomatoes in returnable plastic crates; and use of raised platform solar drying for tomatoes. The pilot projects revealed a 32% increase in the loss of Grade A quality tomatoes when using raffia baskets compared to crates. Raised platform solar drying produced better visual quality tomatoes, with no contamination by dust and sand, and an average price increase of $0.54-$0.86 kg-1 compared to on-ground drying.
