“…A study in Benin (Boko-Haya et al, 2017) reported a significant decline in the number of plants of this species in recent years (Boko-Haya et al, 2021). Several countries, including Cameroon (Shidiki et al, 2021), Ivory Coast (Yapo et al, 2020, Benin Agre et al, 2023Hounsou-Dindin et al, Hounsode et al, 2023;Hounsou-Dindin et al, 2022;Hounsou-Dindin et al, 2021), andNigeria (Ogbuagu et al, 2019), have advocated the integration of R. heudelotii into agroforestry systems, as a means of mitigating this problem. The edaphic (well-drained soil rich in trace elements) and climatic (favorable temperature and rainfall levels) conditions in the intertropical zone of Africa are favorable for the cultivation of this plant.…”

Ricinodendron heudelotii (Baill.) Pierre ex Heckel is a plant species present in the high-biodiversity areas of Central, West and East Africa. It has a considerable potential for development as a non-timber forest product (NTFP). The crushed seeds of this species have traditionally been used by local populations and those of certain large African cities as a spice or thickening agent for foods. In the face of strong and potentially growing demand, not only for nutritional purposes but also for new outlets, efforts are being made in Ivory Coast to domesticate this species with a view to increasing production. A number of actions are underway for the development of R. heudelotii: improvement of its availability; development of seed and kernel production; creation of markets for the seeds and their proteins and oil; development of industrial uses of this oil. This study carried out an inventory of R. heudelotii cultivation in Ivory Coast, and highlighted the levers available for promoting its integration into the economy of the country. The development of outlets for the kernels, oil and proteins of R. heudelotii, the improvement and control of product quality, and the modernization of seed crushing and oil extraction methods are essential conditions for increasing production and for the structuring and expansion of the market. This contributes to both the economic development of this crop and those involved in its cultivation — local communities, and women in particular — and the preservation of the environment through the development of an activity favoring regeneration and sustainable forest protection.

Understanding environmental drivers of fruit and seed production in wild edible fruit species is essential for their valorisation. Ricinodendron heudelotii is an oilseed plant whose kernels are particularly treasured in cosmetic and medical industries. This study assessed fruits and seeds production patterns of R. heudelotii. Data were collected for three consecutive years on 30 trees in the phytodistricts of Plateau, Pobè and South Borgou where it naturally occurs. Tree dbh, total height, crown diameter, number of fruits and seed mass were measured. Climatic data were obtained from NASA Power Database. Data were analysed using linear (seed mass) and generalised linear (number of fruits) mixed models and structural equation modelling. Fruit and seed production were significantly higher in the South‐Borgou phytodistrict (1433 ± 1144 fruits, 4.26 ± 3.39 kg of Dry matter per tree) and Plateau phytodistrict (1.66 ± 0.35 g DM/seed). Tree dbh further significantly mediated the effect of minimum temperature, and relative humidity on seed mass. Tree dbh, irradiance and dry season rainfall were identified as the best‐predictors of seed mass production (kg DM). These results improved current knowledge of the fruit and seed production of R. heudelotii and are of significant importance for the exploitation of the species.
