Njansang -Ricinodendron heudelotii (Baill.) Pierre ex Pax.- is a commonly traded non-timber forest product from Central African humid forests, used as a spice. South West Cameroon was selected as major production area and market where little data exist on the contribution of njansang to stakeholders livelihoods in the value chain. Interviews were used to gather information from 261 harvesters, traders and processing enterprises. From 2013 to 2015, 65.8 tons were harvested, with 13.17 tons traded in markets in the South West Region and in Nigeria for a value of €33,511. The ease of accessing markets makes a significant difference to the quantity harvested and contribution to harvesters’ household income. Average profit for harvesters is higher in regional markets than in local ones. Harvester’s profits were higher than buy’amsell’ams, retailers and exporters. Processors add the most value and earn the highest unit profits. Livelihood dependence upon njansang decreases along the chain, with harvesters more dependent than traders. Seasonality, corruption, storage and processing, influence price. Long-term value chain sustainability could be improved by increasing collaboration between stakeholders, collective action, disseminating knowledge about processing and storage techniques, and promoting domestication and cultivation to enable trade in this largely wild harvested NTFP to continue sustainably.
