An agricultural value chain traces a product from input supply and production, through aggregation, processing, distribution, and finally retail or export, and at each stage, value is added that the farmer can potentially capture a share of. Simple processing, such as turning cassava into garri or flour, or tomatoes into paste, extends shelf life and can multiply the sale price several times over compared to selling the raw crop at the farm gate. Farmers can sell through multiple channels: local markets, aggregators who buy in bulk, cooperatives that negotiate better prices collectively, or increasingly, direct-to-consumer sales via WhatsApp and social media, and comparing channels before committing a harvest can significantly change the final income earned.
