Overview of the establishment and uses of Ricinodendron heudelotii (Euphorbiaceae): focus on the central and southern regions of Ivory Coast☆

Abstract

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.
