“…The fruits are harvested around May until September, coinciding with the rainy season [5]. The genetic variability of shea is noted to be high [7,8,[11][12][13][14] and there is no tradition of planting trees, as shea is highly effective in propagating itself in this environment. Recent work, however, with micro-propagation, rooting cuttings and grafting may allow opportunities to formally domesticate and enrich parklands through selection and planting of more productive shea trees [15][16][17][18].…”

Shea trees grow across 4 million km 2 of sub-Saharan Africa. Shea parklands provide a sustainable source of edible fat (shea butter) that, in terms of volume, is currently second only to cocoa butter as a vegetal source of stearic acid in the multi-billion dollar chocolate and cosmetic sectors. However, in terms of international trade, shea has been opaque to consumers of edible products (where the majority of shea exports end their global journey) and actually only well-known in western markets as a cosmetic ingredient. The millions of women collectors have been disconnected from global supply chains, as the majority of their sheanuts are factory processed, supplied by traders who, in many cases, do not understand quality issues nor share knowledge with their village-based collectors-this is the "Paradox of paradoxa". This review provides the background to this issue by contextualizing the industry and describing how weak post-harvest quality control impacts the shea supply chain. The paper then explains how this knowledge was incorporated into a 3D animation available for free transmission to rural African audiences and viewing on portable devices like video capable mobile phones. This tool offers the OPEN ACCESSSustainability 2015, 7 5753 potential of low-cost multiple benefits to users, which we term here a win-cubed [win 3 ] opportunity, where women collectors can receive free knowledge of using less resources to produce higher quality shea kernels which in turn offer higher extraction yields, lowering production costs, of a better and more marketable product.

“…The high utilization pressure on the species combined with the low regeneration ability cause a steady depletion of natural populations, while no clear and straightforward conservation strategies have been developed neither at community level nor at national level. As the living conditions of populations in underdeveloped and developed countries are becoming increasingly precarious, local fruits could play an important role in improving nutritional conditions and livelihoods of these populations (Tchiegang-Megueni et al, 2001;Kristensen and Lykke, 2003;Mapongmetsem et al, 2008;Oladele, 2011;N'danikou et al, 2011;Dadjo et al, 2012;Sanoussi et al, 2012). Yet, farmers attempted regeneration of V. doniana but faced constraints related to seed dormancy and long growing period, which resulted overall in very poor results (Thies, 1995;Sanoussi et al, 2012).…”

B o i s e t f o r ê t s d e s t r o p i q u e s , 2 0 1 6 , n° 3 2 7 ( PROPAGATION VÉGÉTATIVE DE VITEX DONIANA SWEET À PARTIR DE SECTIONS DE RACINEVitex doniana Sweet est une espèce à usages multiples d'une grande importance socio-économique et commune en Afrique tropicale. Malgré sa forte utilisation en milieu rural, elle est encore présente à l'état sauvage. Il existe peu de données sur sa domestication. La propagation de cet arbre par bouturage de segments de racine constitue une alternative à sa difficile régénéra-tion sexuée. L'objectif de notre travail était d'évaluer deux des facteurs clés (substrat d'enracinement, diamètre des boutures) qui influencent l'aptitude des boutures de segments de racine (BSR) à néoformer des pousses feuillées et des racines. Le système racinaire de 23 arbres a été partiellement excavé sur une profondeur de 20 cm. Des BSR de 15 cm de long ont été disposées horizontalement dans des polypropagateurs sur cinq substrats différents, arrosés matin et soir. Le dispositif était un split-plot à trois ré-pétitions. Le traitement principal recouvrait cinq substrats : terre noire (Tn), sable fin (S), sciure de bois (Sc), 50 % Tn/50 % Sc (TnSc) et 50 % Tn/50 % S (Tn-S). Le traitement secondaire distinguait deux classes de diamètre (0,5-1cm ; 1,1-2,5 cm). Après la mise en culture des BSR, le temps de latence d'émer-gence était de 8 semaines pour les pousses aériennes et 12 pour les racines. Après 28 semaines, le pourcentage de pousses feuillées formées variait de 28 % (Tn) à 55 % (S). Les pousses aériennes se sont développées majoritairement (82 %) sur le pôle distal. Le diamètre des BSR a déterminé le déve-loppement des pousses feuillées (P < 0,01). Le taux de bourgeonnement des BSR oscillait entre 21,0 ± 1,8 % pour les BSR de 0,5-1 cm et 86,0 ± 7,8 % pour la classe 1,1-2,5 cm. Le diamètre a également impacté l'enracinement des BSR (P < 0,001). Le taux d'enracinement des BSR variait de 12,0 ± 2,3 % pour les petits diamètres à 59,3 ± 4,7 % pour les plus gros. La multiplication végétative par BSR peut améliorer la filière économique de V. doniana dans les hautes savanes guinéennes du Cameroun.

ABSTrACT VEGETATIVE PROPAGATION Of VITEX DONIANA SWEET fROM ROOT SEGMENT CuTTINGSVitex doniana Sweet is a common multipurpose species in tropical Africa, which has considerable socio-economic importance. Unfortunately, it is extracted from the wild and there has been little or no focused effort to domesticate and cultivate the species. Mastering its propagation through root segment cuttings (RSC) is a real alternative to the difficult process of regeneration from seeds. The aim of our study was to assess two of the key factors (rooting medium and root diameter) that influence its rooting ability. The root system of 23 trees was partially excavated to a depth of 20 cm. Root segment cuttings 15 cm in length were carefully cut and arranged horizontally in a polypropagato...

“…The remaining nine personal characteristics (Table 2) were not important in explaining people's uses and preferences. Other studies have also found differences in use between villages to be more significant than, for example, between age and gender groups (Kristensen & Lykke 2003). The similarity in answers from the structured questionnaire between, for example, men and women, young and old, different ethnic groups, and religions can be understood by the fact that people eat and live together in large, mixed households.…”

Ethnobotanical interviews on the use of food plants were conducted with 90 informants from two villages in eastern Burkina Faso. A total of 25 plant species and one type of stock cube were included in a structured questionnaire regarding use, importance, reasons behind use, changes in use, and preferences, followed by a supplementary semi-structured questionnaire about reasons behind use, changes, and preferences. Most species were highly used and considered important. Adansonia digitata L., Bombax costatum Pellegr. & Vuillet, Parkia biglobosa (Jacq.) R.Br. ex G.Don, and Vitellaria paradoxa C.F.Gaertn. were particularly important and useful species. Tradition, taste, health, and the lack of other possibilities were main reasons for people using the plants. A decline in traditional food products and an emergence of new products were observed. Answers were strongly related to informants' home-village and project-contact. There seems to be an extensive interest in health aspects and, consequently, a potential for an increased use of healthy traditional products if people are better informed about their nutritive qualities.
